Drivers for light lighters: what should you pay attention to

In order to choose the right autonomous life source, you need to know the main characteristics of the lighter, and yourself:

Voltage in;

The value of the maximum struma mA;

For the light of which the life of the light is born: battery or batteries;

Control mechanism: magnetic buzzer, variable power, tact button without fixation and in .;

And also the diameter and height of the driver.

Presented in the range of ballasts can be mothers of modes in brightness, information about the discharge of the battery, as well as the memory of modes. Thus, the drivers are more functional and handy for victories. Like standard modes (not expanded), you can see a few different ones: strobe, medium and maximum. In the online store ForLed leather hunter, you can learn more about the assortment and buy drivers for light bulbs in Ukraine for a bargain price. At the time of vindication, ask for the necessary professional advice, and the senior managers are ready to provide additional qualifications for help: a report on the characteristics of that driver, and also to propagate the correct model of the dzherel life. In addition, the catalog of products presents all the necessary components for lighters.

Impulse driver for the life of light diodes: the victories of the victorious

You can buy a driver for a light bulb of any type: linear, which drives or pulses, you can in the ForLed online store. The remaining variety of boots is larger than the wide width of the zavdyak to the high level of the KKD (about 95%), as well as its compactness. Attachments of this type of building at the exit create high-frequency impulses of the strum, which pleasantly wafts on the light bulbs. Such a modern and functional driver for a lighter can be bought in Ukraine from us at a democratic and reasonable price.

”looked, zokrema, change of the light matrix into the taken lighter. By the method of supplementing the increase in the reliability of the dzherel of the light for the rahunok, change the scheme for connecting the light diodes from the parallel connection on the combivane.

Svіtlodіodi richly vimoglivіshі up to the zherel of life, lower іnshі dzherel svіtla. For example, the redistribution of the strum by 20% to speed up the term of the current service for a few times.

The main characteristic of svіtlodіodіv, scho signify the brilliance of their svіtinnya, є not napruga, but strum. To ensure that the light is guaranteed to meet the stated number of years, the necessary driver, which stabilizes the stream of light that flows through the lansyug, and for a long time to save the stay of the light.

For low-power light-emitting diodes, it is possible to use them without a driver, but in this case, intermediate resistors play a role. Such a connection was a vikoristane at the suggestion of a greater self-restraint. The simpler solution is to protect the light from the peresshennia of the allowable struma in the boundaries of the rozrachunk's dzherel of life, but the stabilization during this day.

In this article, we can look at the possibility of improving the construction of a higher structure and increasing the operational power of the lighter with the liveliness of the sound battery.

To stabilize the struma through the light diode, a simple linear driver is added to the design of the lighter - a struma stabilizer with a turning sound. Here the strum is a passing parameter, and the voltage of the life of the light fold can be automatically changed at the singing boundaries. The driver ensures the stabilization of the output stream in case of unstable input voltage or fluctuations in the voltage in the system, and the adjustment of the stream moves smoothly, without creating high-frequency shifts of power to their pulse stabilizers. The scheme of such a driver is even simpler to prepare and install, but a smaller KKD (about 80%) is for a fee.

To turn off the critical discharge of the battery (lower than 12 V), which is especially unsafe for lithium batteries, an additional indication of the boundary discharge or the battery shutdown for low voltage is introduced into the circuit.

Driver preparation

1. To complete the assignment of propositions, I will prepare a scheme for the living of the light matrix.

The stream of life of the light matrix passes through the regulating transistor VT2 and the intermediate support R5. The strum through the power transistor VT1 is set by selecting the support R4 and can be changed in the fall due to the change in the voltage drop on the resistor R5, which also works like a resistor of the strum loop. When increasing the struma into a lance, light, VT2, R5, as a result, the voltage drop on R5 increases. Vіdpovіdne zbіlshennya zbіlshennya zbіlshennya z rakhuvannyam transistor VT1, vіdkrivaє yogo, zmenshuyuchi tsim vpruga z urakhuvannyam VT2. And tse curve the transistor VT2, changing and stabilizing the cim stream through the light diode. With a change in the struma on light-emitting diodes and VT2, the processes proceed in a reverse order. In this way, for a turnaround zv'azku, when changing the voltage on the lifeline (from 17 to 12 volts) or possible changes in the parameters of the circuit (temperature, out of the fret of the light) strum through the light with a constant stretch of the entire period of the discharge of the battery.

On the voltage detector, specialized microcircuit DA1, it was selected to control the voltage. The microcircuit works in this way. At rated voltage, the DA1 microcircuit is closed and is located in the black box. When the voltage is changed on output 1, connected to a controlled lancet (in this case - a life-threatening one), to the singing value, visnovka 3 (in the middle of the microcircuit) connects to output 2, connected to the main door.

A larger scheme has been shown for the number of different options for inclusion.

Option 1. As far as connection 3 (point A) connect an indicator light (LED1 - R3) with a positive signal (divided by the principle of the scheme), it is possible to indicate the boundary discharge of the battery. When the voltage drops to a normal value (our voltage is 12 V), the LED1 light turns on, signaling the need to charge the battery.

Option 2. If point A is connected to point B, then when a low voltage (12 V) is reached on the battery, the light matrix will automatically turn on. The voltage detector, microcircuit DA1, when the control voltage is available, connects the base of the transistor VT2 with a glowing rod and closes the transistor, turning on the light matrix. When the light is turned on again at low voltage (less than 12 V), the light diode matrix will shut down for a couple of seconds (per charge / discharge C1) and go out again, signaling about the battery discharge.

Option 3. When options 2 and 3 are combined, when the light matrix is ​​turned on, the indicator light LED1 will turn on.
The main advantages of the circuits on the voltage detectors, the simplicity of the circuit connection (practically no additional strapping details are required) and the extremely low energy supply (parts of a microampere) at the barn station (in the cleaning mode).

2. We select the driver circuit on the mounting board.
We can install VT1, VT2, R4. Let's connect, like a vanity, a light matrix, looked at the cob of the article. The lancers have a lively svetlodiodіv vmikaemo miliammeter. With the method of re-verification and adjustment of the scheme for a stable and constant voltage value, it is connected to a regulated dzherel of life. It is necessary to select the resistor R5, which allows stabilizing the strum through the light diode in the entire range of the planned regulation (from 12 to 17 V). With the method of moving the KKD, the lower part of the insertion of the resistor R5 with a nominal value of 3.9 ohms (div. photo), and the stabilization of the struma in the entire range (with the parts actually installed) waited for the installation to a nominal value of 20 ohms, so there was no voltage for regulating VT1 s- for a small struma, the light matrix is ​​fixed.

Transistor VT1 Bazhano pіdіbrati z bolshim koefіtsієnt transfer strumu basi. Transistor VT2 is responsible for ensuring the acceptable collector streak, which shifts the streak of the light matrix and works the voltage.

3. We add an indicator circuit to the circuit board - a boundary line. Voltage detector chips are available for different voltage control values. In our case, at the connection with the input of a microcircuit for 12 V, vikoristovuvav nayavno, 4.5 V (often zustrichayutsya at the butovіy tekhnіtsі, scho dpratsyuvala - televisions, video recorders). For reasons for controlling the voltage at 12 V, it is possible to add voltage to the circuit on the constant resistor R1 and change R2, which is necessary for accurate adjustment to the required value. In our mode, regulation R2, we have a voltage of 4.5 on the output of 1 DA1 with a voltage of 12.1 ... 12.3 on the tire of life. Similarly, when choosing a voltage dilator, it is possible to select other similar microcircuits - voltage detectors, different companies, name control voltages.

At the same time, we reviewed and adjusted the scheme for spratsovuvannya, for a light indicator. Let's re-verify the robot of the scheme, connecting points A and B, to the inclusion of a light matrix. Zupinyaєmos on the chosen option (1, 2, 3).

Let's take a look at light products, starting from the old 5-mm ones, up to the overdiaspora tight lights, the intensity of which reaches 10 watts.

To choose the "correct" lighter for your needs, it is necessary to sort out in what kind of light for lighters those characteristics are.

What kind of diodes are vicorous at the lighters?

Exhausted light fixtures were installed with an attachment from a 5-mm matrix.

LED lights in absolutely different sizes, from kishenkovyh to camping, became the widest in the mid-2000s. The price has been significantly reduced, and the cost and long term of service on a single charge of batteries have played their role.

A 5-millimeter white nadyaskra light-emitting diode supports a 20 to 50 mA struma with a voltage drop of 3.2-3.4 volts. The strength of the light is 800 mcd.

It’s even better to show yourself with miniature lighters-trinkets. A small rose allows you to carry such a lighter with you. The stink is either in the form of "mini-finger" batteries, or in the form of a few round "pills". Often vikoristovuyutsya in litterboxes from lighter.

The axis of light in Chinese lighthouses is being installed already richly rokiv, ale їkhnє stolіtya progressively merges.

With the help of lighters, with a great expansion of light, it is possible to install dozens of such diodes, and even so, decisions step by step go to another plane, and the choice of buyers falls on the cost of lighters on strained light diodes of the Cree type.

Poshukovy lighter on 5mm light diodes.

Such lighters work with batteries type AA, AAA or rechargeable batteries. Cost inexpensively and play like a bright light, and like a modern light on more hard crystals, but about a lower price.

Nadali likhtarіv vyrobniki sorted out impersonal options, but the market of acidic products is occupied by likhtarі with hard matrices or discrete light diodes.

How do light-hearted vicorist grow in tight lighthouses?

Under straining lighters, they toil on the vase of modern lighters of different types, resting quietly, as wide as a finger, ending with majestic lighter lighters.

For such products, the Cree brand is relevant in 2017. The name of the American company. Її production is considered one of the most advanced light technology in the gallery. An alternative is LED type of Luminus picker.

Such speeches signifi- cantly change the light of the Chinese likhtariki.

How light-emitting Cree are most often restored in lighters?

The models are named after three or more characters separated by a hyphen. So diode Cree XR-E, XR-G, XM-L, XP-E. Models XP-E2, G2 are most often used for small lighters, and XM-L and L2 are even more versatile.

Їx vikoristovuyut, pochinayuchi z sov. EDC lighters (for everyday wear) – these small lighters are less than the size of the serious lighter lighters of the great size.

Let's take a look at the parameters of hard light for lighters.

The main characteristic of light sources for lighters is light flow. In it, lay down the lightness of your light, that amount of light that you can give a dzherelo. Different light, keeping the same amount of energy, can be seriously challenged for lightness.

Let's take a look at the characteristics of light sources in great lights, searchlight type :

Sellers often indicate not the exact name of the diode, its type and characteristics, but shorter, otherwise alphanumeric marking:

• For XM-L: T5; T6; U2;
• XP-G: R4; R5; S2;
• XP-E: Q5; R2; R;
• for XR-E: P4; Q3; Q5; R.

Likhtar can be called like this, “Likhtar EDC T6”, information in this style is more or less sufficient.

Likhtariki repair

It's a pity, the price of such likhtariki is great, like the diodes themselves. І do not start є mozhlivіst pribaty new lіhtar in case of breakage. Let's figure out how to change the light in the lighter.

For the repair of a lighter, a minimum set of tools is required:

• soldering iron;
• flux;
• solder;
• twist;
• multimeter.

In order to reach the dzherela of light, it is necessary to twist the head part of the lighter, it is fixed on the threaded z'ednanny.

In the mode of re-verification of diodes, or we need a support for re-verification of the correctness of the light od. For whom, touch the probes with black and black until the visnovkіv of light, the back in one position, and then remember the red and black with the brushes.

As a reference diode, one will have a low position, and the other will have a high one. In this way, you signify that the diode is correct and conduct streams only in one straight line. Under the hour of rechecking the diode can vibrate a weak light.

And if not, then in both positions there will be a short chime, or a high opir (shaving). It is also necessary to replace the diode at the lighter.

Now you need to solder the light from the lighter and, adjusting the polarity, solder the new one. Be respectful when choosing a light source, pay for your savings and strain, for the sake of insurance.

If you don’t have the right parameters, the shorter one will have a lighter seat, while the higher one will see the driver out of harm’s way.

Driver - ce attachment zhivlennya svіtlodioda stabilizovannym strum in vіd dzherel. Drivers are produced on a commercial basis for 220 volts, for car electrics - 12-14.7 volts, for Li-ion batteries, for example, type 18650. The driver has more hard lights.

Better likhtar pressure

If you don’t have the power of your lighter, otherwise you decided to replace the light in the lighter and wanted to modernize it, first bathe the over-powered models, learn the basic principles of LED operation and exchange in their operation.

Diode matrices do not like overheating - the main postulate! And the replacement of light in a lighter for a worse one can lead to such a situation. Give respect to the model, in which the darker diodes are installed and equalize your own, as if the stench is similar to the dimensions and constructive - change.

If your light is less - you need additional cooling. We wrote reports about the preparation of radiators with our own hands.

If you try to install such a giant, like a Cree MK-R, into a miniature light-keychain, you will see how it looks like overheating and it will be free of charge. A slight increase in tension (by a couple of watts) is acceptable without modernizing the lighter itself.

In the next process, change the brand of light in the lighter more hard - there are more descriptions.

Likhtari Police

LED light Police with a shocker

Such lighters shine brightly and can be self-defense. However, they also have problems with light-emitting diodes.

How to replace the light at the lighter Police

A wide range of models is very important to consider within the framework of one article, and you can also give general recommendations about repairs.

1. When repairing a lighter with a stun gun, be careful, put on gum mittens, so that you can escape the blow of the strum.
2. Lіkhtarі z pilovologozakhisty zіbranі on greіy kіlkostі gvintіv. The stench is waking up for a long time, to work signs, the stars have played that chi nsh screw.
3. Optical lighting system Police allows you to adjust the diameter of the light beam. When sorting out the signs on the case, the details were in the same position in front of the signs, otherwise it would be important to put the block with the lens back.

Replacement of the light source, block of the voltage changer, driver, battery can be done from the standard soldering kit.

What kind of light to stand at the Chinese lighters?

A lot of goods are bought at once on aliexpress, where you can know how the original product is, so the Chinese copy, as it does not match the declared description. The price for such accessories can be equal to the price for the original.

For a lighter, de statements of light Cree, it may not be true, for the shortest time there is a diode in the door of a different type, for a higher one such a name, it will be important to look at the original.

What can you do? Cheap light-bearers wink in low-tech minds and do not see the declared tightness. There is a low KKD, so the stench of the heating of the body and the crystal. As it has already been said, overheating is the biggest enemy for LED devices.

So it seems that when heated through the heater, the strum rises, after which the heating becomes stronger, the tension is seen even more, it is avalanche-like to cause before the breakdown or the urve of light.

If you try and spend an hour searching for information, you can determine the originality of the product.

Upgrade the original and copy cree

LatticeBright is a Chinese light source, which makes it possible to produce products similar to Cree, without a designer's mind (sarcasm).

Correspondence of the Chinese copy and the Cree original

On linings, the clones look like this. You can remember the variability of the forms of linings for light diodes, which are widely used in China.

Designation of lining for LED

Pіdrobki vygotovlyayutsya to dosit right, a lot of sellers do not say about the “brand” in the description of the product and about those, de viroblenі svіtlodіodi for lіhtarіv. The brightness of such diodes is not among the Chinese junk, but far from the original.

Installed light-emitting diode instead of heating lamp

In ancient speeches, fall down with a saw of horse-racing or likhtar on a lamp of roasting and you can easily work it with light. For whom, either prepare a solution, or self-sufficient.

For the help of a broken light bulb and light-emitting diode, if you add a little bit of sharpness and solder, you can make a change.

The air bariled in this weather is needed to reduce the heat input from the LED. Next, you need to solder all the details one to one and fix them with glue.

When folded, be careful - uniquely zamikannya visnovkіv, which has hot-melt glue or a thermo-tubing tube. The central contact of the lamp needs to be soldered - it is opened. Put it through the new winding resistor.

Then it was necessary to solder the light-emitting diode to the base, and the resistor to the central contact. For a voltage of 12 volts, a resistor of 500 ohms is required, and for a voltage of 5 V - 50-100 ohms, for living with a Li-ion 3.7V battery - 10-25 ohms.

How to sprout from the lamp of the roasting of the light.

Pіdіbrati svіtlodіod for likhtarika richly folded, lower yogo replace. It is necessary to protect the mass of parameters: in terms of brightness and kuta rose before heating the body.

Besides, you can't forget about life for diodes. If you master everything described above - yours will make it shine for a long time!

Svіtlodіodi for svogo zhivlennya vymagayut zastosuvannya pristroїv, yakі stabilіzuvatimut strum, scho to pass through them. At times of indicator and other low-power light-emitting diodes, resistors can be used. You can forgive these clumsy rozrahunoks by speeding up with the "Light Calculator".

For vikoristannya pouzhnye svіtlodiodіv not do without vikoristannya strumostabilizuyushchih pristroїv drivers. The correct drivers may have a very high KKD - up to 90-95%. In addition, the stench ensures a stable strum when changing the voltage of the life. And tse can be relevant, like light to live, for example, from batteries. The simplest intermediate struma - resistors - cannot be safe because of their nature.

You can learn more about the theory of linear and impulse stabilizers of the strum at the article "Drivers for light diodes".

A ready-made driver, of course, you can buy. Ale richly tsіkavіshe zrobiti yogo vlasnoruch. For whom you will need basic knowledge of reading electrical circuits and using a soldering iron. Let's take a look at some simple schemes of self-contained drivers for tight light diodes.

Simple driver. Elections on the layout, the mighty Cree MT-G2 can live

The scheme of a linear driver for a light-emitting diode is even simpler. Q1 - N-channel polovy transistor of sufficient intensity. Pidide, for example, IRFZ48 or IRF530. Q2 is a bipolar npn transistor. I'm a vicarist for 2N3004, you can take one that's similar. Resistor R2 is a resistor with an intensity of 0.5-2W, which determines the strength of the driver stream. Opir R2 2.2 Ohm safe strum 200-300mA. The input voltage is not to blame but the great one - it’s better not to overshoot 12-15V. The driver is linear, so the CCD of the driver is assigned to the settings V LED / V IN , where V LED is the voltage drop on the light, and V IN is the input voltage. The greater the difference between the input voltage and the falls on the light diode and the greater the driver stream, the stronger the transistor Q1 and the resistor R2 will heat up. Tim is not smaller, V IN can be larger than V LED on the smallest 1-2V.

For tests, I selected the circuit on the breadboard and powered the CREE MT-G2 power LED. The power supply voltage is 9V, the voltage drop on the light diode is 6V. The driver has been ordered once. І to wind with such a small strum (240mA) mosfet rose 0.24 * 3 = 0.72 W of heat, which is not enough.

The scheme is even simpler and can be installed at the ready-made extension.

The scheme of the offensive self-contained driver is also quite simple. It transfers the microcircuit of the LM317 voltage reduction switch. Tsya microcircuit can be vikoristan as a stabilizer for strum.

Another simple driver on the LM317 microcircuit

The input voltage can be up to 37V, it is to blame but at least 3V higher for the voltage drop on the light diode. Opir resistor R1 is developed according to the formula R1 = 1.2 / I, where I is the required force of the stream. Strum is not guilty of overshooting 1.5A. But with such a stream, the resistor R1 is to blame but the building rose 1.5 * 1.5 * 0.8 \u003d 1.8 W of heat. The LM317 microcircuit is also very hot and cannot be done without a radiator. The driver is also linear, so in order for the KKD to be maximum, the difference between V IN and V LED may be smaller. Oskіlki the scheme is rather simple, it can be chosen by overhanging installation.

On the same breadboard, a circuit was chosen with two one-watt resistors supported by 2.2 ohms. The strength of the struma was less than that of Rosrakhunkov, the shards of contact in the layout are not ideal and give support.

The next driver is an impulsive decrease. Selection of wines on the microcircuit QX5241.

The scheme is also simple, but it is made up of more details, and here you can’t do it without preparing another payment. In addition, the QX5241 microcircuit itself is placed in the SOT23-6 case and takes care of the soldering.

The input voltage is not responsible for overshooting 36V, the maximum stabilization stream is 3A. The input capacitor C1 can be like an electric, ceramic-like tantalum. The capacity is up to 100 microfarads, the maximum operating voltage is not less than 2 times lower, and the input is lower. Capacitor C2 is ceramic Capacitor C3 is ceramic, capacitance is 10 μF, voltage is not less than 2 times lower and more, lower input. Resistor R1 is to blame for the mother's intensity of less than 1W. One opir is covered by the formula R1 = 0.2/I, where I is the necessary driver stream. Resistor R2 - be it a support of 20-100kOhm. The Schottky diode D1 is to blame for the reserve of vitrimuvat the reverse voltage - not less than 2 times lower and more for the input value. І repayment can be strum no less than the required strum driver. One of the most important elements of the circuit is the half transistor Q1. Tse can buti N-channel field worker with the minimum possible support at the open camp, insanely, guilt is guilty of the reserve of vitrimuvat input voltage and will require the power of the struma. A good option is polovі transistors SI4178, IRF7201 and in. Throttle L1 is responsible for the mother inductance of 20-40 μH and the maximum working strum is not less than the required strum of the driver.

The number of parts of this driver is small, the stench can be compact. As a result, you may be able to complete a miniature and sometimes hard driver. The price of the impulse driver, the yogo KKD is significantly higher than that of the linear drivers. Tim is not less, it is recommended to increase the input voltage by 2-3V more, lower the voltage drop on the light diodes. The driver of the cicavia y y tim, scho output 2 (DIM) of the QX5241 microcircuit, can be vikoristany for dimming - regulation of the power of the strum of the driver and, apparently, the brightness of the light of the light. For this purpose, it is necessary to apply impulses (SHIM) with a frequency of up to 20 kHz for this output. It is possible to get into it if you are a viable microcontroller. The result may have a driver with decalcom modes of operation.

(13 ratings, average 4.58 out of 5)

The first part about tuning and the repair of light, is introductory. Here we will look at the main designations of the average statistical light, the parameters of hard light diodes and a little bit of tedious mathematics associated with them.

Otzhe, you have a bright light, ale vin burn, or you don’t rule for the power, otherwise you want to turn yoga into a zbroyovy. What are your options? Let's take a look.

Construction of a spherical lighter in a vacuum.

The most important light is composed of the following parts:

1. case - a typical tube with cuts on the tips;
2. battery - live in the middle of the case;
3. end button - screwed into the case on a thread to serve as a switch on the lighter. Other lights can be completed with another backdrop from a wine button;
4. the lighter's head is screwed into the body, it can be closed in front. Sometimes the detail is random (like in the photo, two parts), sometimes it is not;
5. light-producing element - combining into one block a light-emitting diode, a light beam shaper, a heat-insulating light-emitting diode and a light-emitting diode driver. Sometimes it is released from the head of the lighter.

Light-promining element.

Tsya the collection itself can be a different vikonannya. Even wider heads for the Ultrafire WF-502B lighter, stinks are sold in different types, different tightness, with a couple of functions, etc.
For example, on fasttech.com. Lights with this type of element are good because you can buy some modules for different jobs and just change them.

Svіtlodiod is still a lady calm, vin merits on the edge of view below, the driver is basically the same, and the axis of the details, which are left out, we can see at once.

The light beam shaper is available in three types:

1. lens- The simplest and least effective option, because not all crystal modifications are taken from the light beam. Even more often the lens can be moved, changing the focusing of the beam of light, which is the only plus of this solution.

2. collimator- a part made of translucent plastic, vikonan for picking up a beam with specified parameters. For whom the collimator should work in such a way that it confirms the main design of the lens on the light diode, then put the collimator in the form of one light diode on the light diode if it is not visible - the parameters of the light beam will be different.

3. vidbivach- the design, which came from the heating lamps, was adapted to the light source. Simple, nadіyna that perevіrena hour design. Vzagali, vіdbivach yak і kolіmаtor is optimієєєєєєєєє pіd svіtleny svіtlodiod, аlе s less criticality. On the right photo, you can see that the crystal of the light is shining through the whole area of ​​the light.

Indeed, the replacement of light is as full as possible, like the replacement of a vidbivacha. Buvayut as if with a smooth surface, which gives a hard promin, so with humpbacked ones, the less remaining ones were more worthy of the occupants.

Thermal insulation, in the same case, to which the light driver is often screwed and into which the light driver is mounted. As a rule, the insurance on the installation of a light-emitting diode on the lining is an aluminum plate, to which the light-emitting diode is soldered. The photo shows the mechanical components of the module. Zlіva to the right: vіdbivach, teplovіdvennya, spring for negative vivendennia (contact with the lighter's body) and spring for positive vivendennia (contact with the plus of the battery). The remaining spring is soldered to the light driver board.

Parameters of light diodes.

The main parameter for looking at the brightness of illumination is the spectrum of vibrance and brightness. , structurally it is determined by the tricks of the phosphor. Unfortunately, this parameter may need to be changed for different series of one generatrix. And Liao himself does not know what to smear uncle Liao at his basement. Cheap lights for a hundred and a few lumens are charged for the brightness of illumination (because You can clearly see the details of the illuminated object, and the small details of the lighted object can be seen with an eye that is no more than hard lights with halogen lamps.

Serious guys in the Cree individual are setting up an upcoming schedule for the development of their XM-L light series. It’s a pity that the average values, the naskolki wines are equal, which are failures, we don’t even know. On the horizontal line, there is a slight sagging, on the vertical line, there is a tension in the veil.

Three curves are drawn on the graph - for different color temperatures. It can be seen that light with a lower temperature (chervony) climb into the infrared region (douzhina whvili more than 740 nm), but even a little and not far - there alone a hundred of tightness vibrate. This is the reason why it is impossible to take away a decent white lighter from a decent infrared lighter by adding an infrared filter (as it is easy to fight with a lighter with a heating lamp) is impossible. Svititi vin will formally be, but KKD - none.
The color temperature is a companion parameter, without interfering with the spectrum. The color temperature is shown as the temperature of an absolutely black body (such a cunning fetish of physicists), with a certain vibrance of the same color tone, which is a vibrancy that is seen. For day light 6500K, for heating lamps 2700-4000K. The less color temperature, the more yellow light near the light.

Behind the special warnings, with light diodes with a lower color temperature, the details of the objects that are illuminated are more clearly visible. Accept for me. Not a lot of light of the warm white light, and there is less light in the air - the stench is less bright, the lower "spekotnish" brothers.

Friend, what to squawk us is the lightness of light. It appears in the documentation as a bright sound with a singing stream through a light-emitting diode. For example, for the chosen XM-L, the color of different strums is assigned. For example, XM-L T6 at 700mA (2W) may be 280 lumens (400 lm/A), at 1A may be 388 lm (388 lm/A), at 1.5A - 551 lm (367 lm/A), at 2A - 682 lm (341 lm / A). At the temples there is a pet yaskravіst fallow in the struma. Vaughn falls by 17% when the struma rises from 700mA to 2A. Tobto greater strum, then less pet yaskravist, then lower than KKD. Behind the schedule, before the speech, you can honestly see.

Another important parameter of light is light intensity. Tse is maximally tight, as it is possible to “breathe” in a new one. Zrozumilo, at the maximum, life is less, lower, at less tightness, it’s better than yogo troch “not indignant”. At its heart, the tension indicates the maximum strum through the light. As a rule, the intensity of that strum through the light diode leads to a non-linear fallow, shards to fall further in the presence of a voltage drop on the diode. Axis for XM-L: horizontally direct voltage drop, vertically strum through a diode.

The voltage drop on the light diode is typically close to 3 volts for a white light diode and to lie in the stream through the light diode. Looking at the graph: at 200mA, there may be a drop at 2.7V, at 700mA - 2.9V, at 1A - 2.97V, at 1.5A - 3.1V, at 2A - 3.18V.

For example, take a tricky light type MC-E with a choice of crystals, 350mA - 3.1V, 700mA - 3.5V. Even more dim the crystals by 10-20 W, the voltage drop is close to 10V, and even more dim ... well, maybe even more.

Before the speech, if you want to translate the lightness of the fallow into the stream of XM-L to the lightness of the fallow into the tension, then we take it that we have at the stream I = 700mA and the voltage drop U = 2.9V, the tension is reduced to 2.03 W, and the light is 280 sweat , then 138 lm / W. Prodovzhuєmo far and half for 1, 1.5 and 2 A struma is apparently 130, 118.5 and 107 lm / W. Retail at 29%. Axis and break your head, what mode to choose.

What are we to know? If you want to understand that, like eating the same food, you can use that chi of the lighter, which you can take away, for some other light you can replace the light of the lighter that you burn. Ale, the picture will not be the same without knowing about the life of the light.

Life of the lighter.

As a rule, vicorous lights have either lithium batteries (nominal voltage 3V, zbіgaєtsya with the maximum and when discharging it drops), or lithium batteries (nominal voltage 3.7, and the minimum and maximum - approximately 3.2 V). , you can read about batteries, there є about types and їх vіdminnostі).

Before speech, batteries, like in the photo, I would be unique if possible. The quality is not high and the capacity is highly dependent (from the statements of 2500mA / year there is good, like 1800 will be). It is better to take Samsung firm middleware and others. Bad battery cores can be used from these batteries for laptops - they will be better than the Chinese ones, tortured by narzan. If you want to navit the Chinese people have "in the middle" normal middles.

Sometimes the light bulbs have finger batteries, but the stench is rotten with the flow of strums, the necessary resuscitation of the strained lights. If the lighter still has finger batteries, then you won’t be able to fix the problem with low power.

Drivers

It is important to have more light on board, one light is about 3 watts. Tobto vіn mає pаіnnya vаdіnnya prugi close 3 Ві strum close 1 А. Such lighters may have some kind of driver circuits, even if they have a power cord to extinguish the voltage. When installing lithium batteries, you need as many as two pieces, and the CCD is catastrophic. Good, that the normal impulse drivers of the light sources may have been more likely to get a cheap strum dzherel. In lighters, like vicorist, there are a few elements or batteries, and there is a pulse driver.

You can choose a driver in front of you for the presence of the cat. Yakshcho won є - chanting tse pulse driver. How good are the veins and what are the ranges of input voltages to endure? Here you can find documentation on the installation of a new microcircuit. For example, for the middle driver in the photo (Skoda, rotten) you can use a magnifying glass to mark the 2541B microcircuit and for it it was possible to know the documentation (Chinese), it has an input voltage of 5 to 40 volts, but CCD is not indicated. Also, if you take a top light with a CCD of 30-40% and a good impulse driver (CCD will be close to 90% in an ideal situation), you can take a lighter CCD of 27-36%. Not so bad already.

A butt line driver on the same photo at the lower right kutka. All the electronic filling is brought up to a power diode and a few linear wires of the struma, which work in parallel. You can estimate yoga KKD as changing the voltage at the output to the voltage at the input. If you power the circuit from the battery, then the maximum voltage is 4.2v, nominal 3.7v. To the minimum speed for everything on the right did not work - the driver needs a minimum voltage drop on the voltage supply, so that it works. Otzhe, rahuєmo 3/4.2 = 70%. However, if you want to shut up and not beat the battery, then you need to plug it in with a pair of lithium batteries (2 to 3V). Todi KKD will be 3/6 = 50%. Not much more curly, looking at the CCD of the crystal at 20-30% and, as a result, the CCD of the whole lighter at 10-15%. I guess, I realized that line drivers need to be unique?

Often, drivers are installed at the lighter, which they support sprat of work modes- Povna poguzhnіst, srednya, zanizhena that all sorts of blinkers. In the photo, such a driver is left-handed at the bottom. Moreover, in cheap models, the qi modes and short-hour rosemaries of the lansyg are mimicking. Tobto trochs pressed on the button - the light was extinguished and, upon admission, it worked in the new mode. I can’t stand them, it’s better for me than any change of regimes, lower like that.

Don’t worry, but in some models, you can let the lighter in such behavior and override the robot with the wine button (at the sight of a broken lighter). Ale tse already okrema topic.
