About led optics .
Six months later, I'm back. Have something to say, have something to show. April moved from Toyota to Lexus (I think in the next building, the firm is the same). More expensive cars, more electronics, more interesting to work.
Why conventional collimators are not suitable as a low beam headlight.
I explain on fingers. For starters, look at how all Shine, let's say, a conventional flashlight. Here we have a lantern, it shines a cone with some there is a different angle. Divide this angle into equal intervals, say 5 degrees and get such a picture.
Left imaginary light source, the total angle is divided into equal sectors.
In each sector the amount of light the same. Here we aim a flashlight at a wall, what happens? Round, brighter in the center, to the periphery dims, schematically it will look like this.
The farther from the center, the large area accounts for the same amount of light, hence the decrease of the illumination to the periphery. What happens if you try to portray Faro and direct the flashlight at an angle?
As you can see, there's still more running, more and more sharply increases the area per the same amount of light. It would seem the obvious thing, the farther away, the less light, it's logical. But that's not the explanation, the light is almost not absorbed by air, so what's the difference, what is the distance from the light source to the illuminated surface? It's not the distance, focused beam will hit for miles, even with modest lumens. All the explanation in the figure. Oh, by the way, what we get from the top view? That's right, the parabola.
Not the best solution for the headlight.
Goes to light something even, the light source must not Shine uniformly, and on some tricky law. Clever in the literature there is a term, as curves of equal brightness, which describe the desired light distribution. For example, you can make the street lamp that will draw on the pavement fading round and evenly illuminated rectangle that implement modern street lights.
A sample of dataset led "glass" of street lighting.
Same with car headlights, the main power light goes into the distance and the closer to the bumper, so it is less in order to obtain the same illuminance. Now you understand why it is pointless sounding questions, with what angle to take the homemade collimator for the beam? Yes to any. And not being blind thing, what basically and obsess people. By the way, it is not difficult to overcome, you can put the visor and the problem will be solved, the benefit of led collimators compact. Look again at the third picture, in principle, with LEDs with uniform there will be a little better, since the light distribution from them is not uniform, forward they Shine brighter than the sides, so the figure in the center of the axis of our cone of light will be larger (just over a larger area) and then the brightness will drop dramatically. But from this picture you can see that part of the world just goes above the road, in the air. This net loss. I experimented with the flashlight, collimator at 45 degrees gives a nice fill, provided that it shines almost horizontally, i.e. at least half of the light goes up. Although car headlights, to some extent, decide the question in the forehead. For example, caps on the light bulbs, which cut off the light beam in unwanted directions. Blinds in xenon lenses, etc. And what will happen if you develop an advanced led optical system, without blinds, which will all the light be directed to the road? And I'll show you now what will happen...
Optics decides.
I got the stuffing from led headlamps Lexus. Three led modules, each of which consists of a radiator with led, reflector and lens. One of them I designed in the form of a flashlight, gave him 5W and went out into the yard. I will say that the lumens in the flashlight I've been think, since last year. Rolled with 270Лм 45 degrees (three odnoletniki), in the dark not very bad. Tried the flashlight on 210Лм with tunable optics. With the headlamp on 270Лм light, almost staged. Ie I could safely go in the dark with any desired speed, even 30km/h So I'm wondering, I guess 500...800 lumens with a good light distribution can give an uncompromising light. So, a piece of LED headlight Lexus 5W the led, how many lumens do not know, I think a 550...600. Are you ready to see it?
This is my velofara. It looks amazing...
But as Shine mentioned 270Лм 45 degrees (3W).
But so Shine the headlights of my car, the engine running, clean, with normal lamps. And the lights themselves are normal (multi-focus reflector, smooth glass), the light is not complaining.
Then what photoshop yesterday for Facebook.
net/45e4362s-960.jpg width=960 height=720 itemprop=contentUrl>
No cheating and forgery, was shot all with the same exposure, which, in fact, seen through the clouds. Light, of course, less than that of the headlight, as it should be. But the head does not fit, how can I cover this area with five watts, effective range of about 40 meters. The scale of the bike, by the way, it's more than 3 seconds of movement at a speed of 40km/h, i.e. by the light of the limitations just no. Imagine that you have on the car so light that you go 200. Here's what it is. By the way, measured consumption of led headlamps Lexus NX, 24W on one dipped beam (ie a total of 48W to the middle).
Yes, there is video. Exposure is also locked.
So it looks on the wall.
Quite the circle doesn't seem right? Look carefully at what I wrote in the first post: the higher, the brighter the spot, i.e., the farther the more light. The result of the photo is visible, shading is very uniform.
Photos lenses.
4 of the crystal series. Considering that high power LEDs max. voltage on the crystal is about 3.5 V, maximum power approximately 8W as at 14 volts (4 x 3.5) to obtain the current in 0.6 A
Fitting after manufacture of the attachment. Here yet without sealing, in the future, covered all the holes with sealant. In the future, will be refined.
Hard to be a God. Ofigevayu from such all. I ofigevayu, following me, facing pedestrians when I catch up with this light facing counter and passing cyclists. When I drive, the light hypnotizes and enslaves me, I look only at him and the reaction of others. Don't know when to calm down and I'll just skate.
UPD 27.05.2015 Used to just ride.
UPD 29.06.2015 This post is very alarmed the public, many have wondered where to get a similar. Who searches — that will find. Comrade ntrofim found here is the Chinese Seem to have started to receive the LED modules for retrofit! Hurrah!
UPD 02.07.2015 the lens, which is the largest, it appears, from the Prado. That friend was apart, I had exactly the same (was in a poor state of reflector, gave it). www.drive2.ru/communities...76151742351/forum/8338756

Creepy perhaps, when the back is catching up.Even with half capacity of the ride would be afraid)
Found something similar, are they?

Cool modules! Only the price tag of a horse! Someone is taking? How they Shine?

Well, Yes, in all of this, somewhere else the light bulbs remain.
Clear. I tried to dig into the theme through the book, is considered mandatory tutorial on illumination. The author I do not remember, is called "Light devices", volume tutorial. The point is that even with their education in the field of optics there I nifiga not understand. There with formulas, graphs, and really without explanation, based on the fact that you're not weak understand all this :-D Then I realized how serious this is. If it is to master, then the next stage is to deal with the programs of the calculation of lighting, and then have the little things to make the optical system according to the simulation results. Yes, definitely interesting. Good results are obtained with the optics drawing on the wall of a narrow strip. I have one such lens purchased e-neon.ru on the way from it turns out very decent shading. But the problem is that in the lens of a monstrous loss, percent commercials 60...70. And, as far as I know, they're all the same. Even a simple riflenie on the collimator gives a strong loss.
look in the Luggage compartment and razocarana, two side light floating C8w lamps. ))
on the crossovers and vehicles without 3rd row seats
Goal. personal experience. + led PTF, its. with a good STG. I liked STG 570-M. and Bicycle lights.
And what purpose? Make your led spotlight? Modules for retrofit would be interesting to do. Still interested to release the flashlight so the right light. Tellingly, now they do not exist at all. The coolest thing is a pair of collimators with different angle and with a small rifleniem the top to the upper part of the beam went down, not up in the sky, are the lights in retail under 8000R.
About illuminated visor need to look, not paying attention. But overall, the Lexus I looked hard enough for the LEDs bother. Tricky optics for the lighting of the rooms, led daytime driving almost the entire lineup (and decorated it, as a rule, as usual xenon — single, circular lens). The interior lighting is usually well done, mate always light such that the light source is almost invisible, it does not blind. Basic lampshades with a good lens, the light is very soft. Well, the total number of highlights is like a man who did not know where sveiki squeeze in ))) only Recently noticed that NX already handles on the outside are highlighted. I want also to tell about all that, but I don't know what format to describe it. For now just take pictures of what seems interesting.
If you have a craving for knowledge, if the brain isn't full of cobwebs, you can always try. especially if there is at hand a machine capable of cutting aluminum, and programs for calculation of optics. it remains to find the time or intelligent associate that can help.
In the cabin light. I crossed some Lexus. I realized this when I crawled in detail and measurements of 570 minutes. they are less my care about the comfort of the consumer in this area.
To verify my words. can. sit on the passenger seat, open the visor, smile in the mirror and open the shutter fully.
and then with intricate spells and complaints on the blind eyes closed the curtain back.
This is one example. about the Lexus.
Please. To understand something there is not difficult, a few Svetikov, downward, multi-focus reflector. Only to sense from this understanding, it is not to reproduce itself. NX have the same tomance.
for so long I licked around PTF 570-M. tried to provethat to understand that there is and all the secrets inside )) thank you. have everything in trunk is pulled ))
Cudzo
Beauty! And you can detail what kind of headlamp (s) from Lexus? Too such want!
Prado, Highlander, Qashqai, x-trail, patrol — the latter have the same mono led module Koito.
Well then you need to look for led modules beam out of the car. Which, I think, not very important.
Led modules beam (by cut-off boundary). Details I do not know. Don't even know what this machine and from one machine whether it is at all. If you are in the car, it is easier to put xenon in relation to cars is nothing particularly cosmic about them.
Yeah, shining cool))
With this light all cyclists f shock))
Thanks for the report)
tin of course, the lights on the bike to have) pedestrians can burn in the light! like vampires in daylight)
but the light, m@t it just gorgeous!)))
I even do not understand, You in the laboratory of the Lexus secret technology stolen into Les? :)
I thought about it )) am Inclined to think that we should try to make a simple mechanical system to tilt the spotlight with helm. I've seriously thought, and as the same motorcycle to solve this problem?! P/s and nothing! :-D Now, with 50 seconds is seen 
lllPrizraKlll
system tilt, gyro needed, and generally easier to do additional lighting on the sides that some led luminaries and not to hammer head with all sorts of systems tilt
There's more annoying is that you have to redo the mount. And I've been thinking that in the end everything turned out just as pictured.
Yes, just the mechanics. To make cravings, which will tilt the headlamp and all. Although additional light is also normal.
system tilt, gyro needed, and generally easier to do additional lighting on the sides that some led luminaries and not to hammer head with all sorts of systems tilt
Not much help, the roll will stay. Need to do system tilting spotlight along with the bike, or extra light.
well, bike Yes, that is a problem that can be solved only by installing lights on the frame, not the wheel
Yeah. It would be desirable, of course, is to see those lights on the car the original Shine at their full 40...two 60W lights or whatever they have, I don't know exactly (with the time required to measure the consumption on the car). About clear distinction can not yet say anything, besides, it can be seen only "in the tunnel", when the sides got something, and it's not visible. There is more inconvenience in the corners, the horizontal collapses, with the outer turn side light goes up and the inside of the turn in the ground, in the end, the twists are not highlighted.
Yes, everything is up to the reflector, specially designed for led reflector, everything else is nonsense (SD in halogen lights, tomance etc). And the light is just gorgeous, xenon resting. One drawback is the sharp cut off of light, there is not much, supposed to be a little stray light, a light flare above the main border.
No, no, we have already closed everything. While in a hurry, over time will improve.
And on top of the lens and plan to leave the gap? after all, dust and drops to get will.
Maybe not rest, but a bike space! Especially before eyes there is no glass, no glare, so the need for brightness is much lower.
That's what I understand the dim light, a xenon modules play compared to this led.
Yeah. Himself in shock. Not, the aggressor. My brother pressed, he was not riding and he got a gift :-)
To get and not to get up, the light is gorgeous, thanks for the article, very interesting, great Avalanche 2.0 ?
Yes. In principle, such things are already on sale. Apparently, with split headlights from the analysis.
:-) Not an expert and do not understand that this led lamp :-) I'm in the Lexus with experienced been cut on account of the fact, xenon or LEDs on a given machine. Although enough just to look at off spotlight at a certain angle, there is bound to led to be yellow.
Thank you good people. And then summaries of MSK stole the headlight and bumper picked))
They are all three different. Measure, if not forget. The smallest, the one I used are about 6mm in diameter.
Yes, free give. She's the only one without led. Of the three lenses with led only one was. But the installation location of the Shine is clearly marked, you can be anything when you adapt.

Work there is not a lot, the module is ready got. Certainly possible, a lot of cars with led head light.
Can I pakazanuju? I'd buy if cheap

Barnumber in the Studio, we look at the disassembly, you really want the right light for led
just wanted to prove to myself and others to show that such))) and many believe that led can't be beat xenon)))) I think now, as if to collect his fare)) the light is frankly not impressive, but the xenon is not the soul)) of the modules are certainly not find, so let's reinvent the wheel again)))
Work there is not a lot, the module is ready got. Certainly possible, a lot of cars with led head light.
always thought that the led to collect headlight replaces halogen, and xenon is possible, but the work is not allowed to work on it in earnest, now there is no need, everything is proved!)))) well done, good job)
Yes! At least, by the fact that everything else you can buy, and Faro this can not be bought :-)
Yes, the led module Assembly (heat sink with mounted LEDs and it screwed the lens with the reflector). From alterations the manufacture of fastening, sealing and fabrication of the driver. The driver found in the bins, doing it just for a test boost, put only the desired current. Nourish, usually of 7.4 volt of the battery, and the led needs about 13V.
and on led did you fully (lens and led) headlight of the Lexus? That is, without modifications, right? Or is it doing something? If you do, then what?
Thank you. Yes, as a rule, are the same they are. Lexus Toyota led light in General is not particularly ofishiruyut design and decorate ordinary size lenses.
On account of the 50% don't know, but "reflenye glass" on the amount of light on the road exactly to compete. And the flatness of the fill probably 90% of cars will surpass :-)
Yeah) that awkward feeling when the light on the bike is better than 50% of cars)))
No, no. Yourself accidentally in trouble. If anything else would benefit from it, so have all of your friends lined up behind them :-)
No, no. Yourself accidentally in trouble. If anything else would benefit from it, so have all of your friends lined up behind them :-)
Excellent light and outputs you have on such optics have? Even broken lights, very interesting-would have been set.
Fuck... Dude you have a bike light is better than I have in the car...(can't commentary, no swearing, do not convey a lot of emotions)
Given the fact that she is on the bike, yeah, it's incredible. So, as planned, in the light of no limitations illuminates so that you can go at any speed in the dark. Recently a couple with another cyclist at night in some garages flew downhill, without any problems, you can see everything. And if you get off the led, take him behind the wheel, you can just as the flashlight to use in order to look around.
Damn, again after "recommend" chain reaction went ))) Yes, normally all you have xenon. I have the brightness on the road is still not the same as a normal headlight. Not far away is still okay, but from 20 metres and then quite dim. Here on 5W led and in the original there is about 50W (two headlights). Halogen is a little brighter, and the normal xenon my bike headlamp in smithereens shares.

Hi. Thank you :-) Let's drank his already :-) and You feed it will be easier, from two Li-ion can be a simple driver to do, not necessarily impulse.
And where I have Lion? I lead looked))) 3 A/h 6v.
And the driver took on 3 watts. On trial. And maybe it will suffice.
He's at recess 12V. So I think the bridge desoldering a that loss excess to avoid...
Hi. Thank you :-) Let's drank his already :-) and You feed it will be easier, from two Li-ion can be a simple driver to do, not necessarily impulse.
Finally, my friend gathered a bunch of ideas)
You're great!
The word "great" of course... and voobshe)))
Thank you. Yeah. I first saw, was very surprised that the reflector is continuous, that is to say, not multifocal as a conventional halogen headlight. As for recoil, it's not definitely all. As it turned out, a powerful matrix the impact is less than the total output of the individual crystals due to the interference that occurs between light of individual crystals (when a lot of them). For example, some Cree-XML this is not a problem, because there is one large crystal, but technically, led is considered as a matrix. These Svetikov, it looks like 4 separate crystal at 2W, but they somehow look apart, I think around the world they work independently and with the output everything is fine. But it's just thoughts, probably don't know. You can try to learn new directories Osram, then you can navigate.
class
that's what it means, properly designed optics.
hardly there >100Лм/W, powerful crystals is still exotic. More real ~80-90Лм/W. But optics - it is a real high-tech.
Yes, led directly to send makes no sense.
I have now is xenon in the PTF, I tried to make the curtain, wrapped the lamp paligoy in the right places, but never managed to make a clear STG.
therefore, to put an led like a light bulb that makes no sense.
And here I thought that the lens works basically as a lens and as a lens to try to use the lens standard.
well, thank you, will do and share the result))
Hi. Thank you. I'm afraid the reflector so you don't do. In a few words to explain, so you better do as you are doing. The only probably the most optimum arrangement of LEDs, here is how i00.i.aliimg.com/wsphoto/...-Led-Headlight-1200lm.jpg Two LEDs back-to-back to each other. Well, or one will light up only a part of the reflector. As it will Shine — it is unclear. But certainly better than if the led is just a forward to send.
Hi. turned out pretty cool))
Please tell me, I ordered LEDs 10W 900Lm around, should arrive soon. I want one led to put in the PTF, and to obtain from them the maximum light efficiency, ie that you have in the lens all of the light directed to the road and not anywhere.
Tell me if I will do the same reflector, but instead the lens itself will stand glass PTF 2110 usual relief, if I can get hold of STG and light dispersion to the sides as it makes the lens?
PS, I know that you just need to take and to do, but I think whether the sense, the fact that I do not know where to find the lens separately at a reasonable price.
thanks in advance!)
Hi. No, I have not seen the light now too. Well, I have there lights and more! The brightness of the flashlight is not so high. And Lexus, I think it's OK :-) In runoff and the capacity is almost 10 times higher and headlights two (and this is also a special pit highlights), and in each lamp, two modules, and one figure they are a little different.
The question suddenly arose! And Lechusa head led light works have you seen ?
Just, again comparing photo flashlight photo of your car, suddenly thought of a car despite the lack of availability of such a chic STG visibility still more comfortable
Oh yeah! Thank you! Kick there Valerie, let her finish. The second lens he got, if not aware :-)
Put another signal the guns zoom like a chimney

Oh! The chinks seem labored! Yeah, similar. Only here and near and far. The price is not very clear, each individual put up, it seems. How do you count? The request did not? P/s will put me this reference in the text of the post.
But the quality is questionable. Even though the curtain as the xenon, and reflector compared to the Lexus has a very simple form.
If Alibaba give search DOHON LED Projector lens you can still something interesting to find. There is a car. Specifically for motorcycles is. You can apply for a big )))
Oh! The chinks seem labored! Yeah, similar. Only here and near and far. The price is not very clear, each individual put up, it seems. How do you count? The request did not? P/s will put me this reference in the text of the post.
Eh, not such toys to give away :-) Well that sounds about right. Now remember, the led light I was shooting with this lens and rearranged in a little. So it is necessary to try to give watts 15 — 20. Out voltage to the crystal they have much more 3.5
About how! One of the lenses that I got it. Just DRL across from predica, apparently, and the middle with the same spotlight. And there is the opportunity to take a picture of the led next to the ruler? If it is just the same (well), he did not 8W as I thought, and all 20.
Dismantled the diode block from the Prado

See even little by little they will begin to appear on the secondary market. If for a Bicycle, it is possible to alter them under LEDs. The losses will be bigger, of course than mine and the shading is not so smooth, but is likely to be much better than any factory flashlight.
hmm, need to sort out the remains of the lens in the garage)))) from VAGов and Toyotas of the lens but under the xenon and halogen...so the LEDs are not seen even once...
Nothing much interesting there will not see a smooth reflector cunning shape, small nodules for the formation of a Daw. Almost all of the light from the led directly into the reflector. The link, too, all wanted to try. Now it is not relevant.
I want this in my hands at least for an hour or so to play with...
see what show: www.drive2.ru/b/2106516/
Actually, I was thinking the WHOLE car light for LEDs to translate. Some put with the regular caps, and then entirely replaced. When a single costs in the future will be saving lamps, improved reliability, and savings on gasoline (of course not large, but the generator will also be safer with less stress).
PS. GT taxis, yeah :)
Thank you. With the machine easier, it's just a good xenon lenses to put :-) This 35W not feed, I was even thinking about 25W xenon (D5S I think), bulbs compatible with D2S lens, Yes just one light bulb with integrated ignition 5000+ rubles worth.
Perfectly written! Loved it :)
One frustrating, now I have to go for examination and to cram the optics from Lexus in the spotlight :))))
Alternatives are actually a lot, just need something to pick up, buy and power, respectively, all of this farm!, and for this just buy a 18650 battery, solder them, and wrap tightly to power the driver, and both Ali like very much. I myself use such a lamp, but not on the bike as at work, on the bike will also be gorgeous, that's the lamp I have — zebra h602w. Here's a look at slalom: 
Thank you. Well, I do not 50. Now set LED tomanak within 10000r you can buy two led will be enough light in about the same. Really healthy they are.
Yes, You have a headlight on the bike for 50,000 rubles worth. Super, super light and light!
ISVLabs
well, just a great review, thanks!
regarding the specifics of velocita will add a few words. about that headlight with the bike leans in the opposite direction from the rotation previously discussed. never thought I would such an effect.
notice that the bike is very important to light up and generally side illumination. light up will protect from branches in the woods, trying to snatch the eye. and side illumination in General removes the "tunnel effect" and makes the ride more comfortable. for this reason, I usually advise against very bright light, because it completely kills visibility in peripheral vision and General eye when riding at night. the light should be in moderation! adequate speed and driving conditions.
I little experimented with lenses and lenses on the bike — didn't have time and possibilities. but well a few years went from "finished" (in the literal sense of the word) flashlight with extended focus and wide beam. beam, at the same time, I lowered so that the far edge of the hotspot was at the limit of the required visibility of the road (total braking distance with the stock).
now over at handmade and ride with the Chinese headlamp for 3*XML in the diffuse variant (the latest version of the same lights friends came very focused). minimum mode is enough for leisurely driving in town, in the forest average. well, the maximum in the extreme case, have in stock :)
Normal flashlight too saves, I agree. If the oval diagram, so all is well. I experimented a lot. I have one lisochka, which is generally a flat rectangle draws, with her excellent shading work. The only problem is that it is the loss of 70-90 percent of the commercials (2W 10W Shine worse than an ordinary LED flashlight). Yes, and the brightness all the powerful lights of other cyclists Shine much brighter due to the fact that stain less. And this really affects the visibility in the periphery. That is, when they have their lights off and only my headlight to be seen, and farther and dark spots more visible.
Thank you for the detailed review. About the light up he already knew how the ride with this miracle. One really happy little head blown off when driving through an unfamiliar yard pipe for drying clothes late notice.Light sideways, in principle, enough, she shines greatly. The effect of the tunnel there is, in fact, only in a tunnel (narrow spaces), the vast STG no on earth is no longer visible, the upper border is far away. I have another fork straps made. pp.vk.me/c623426/v623426704/381db/qj7RH-5S14c.jpg Made two brightness modes, dimensions and DRL (daytime go with them), in the regime of maximum brightness (about 2W) is quite good rescues in the forest. In General, Yes, wild places need more overhead light, I think, more then anything will do. Need a separate post to gash, I have since then much has changed, came back size, made of human control all of that stuff on the stem, there the same drivers and hid everything.
For brightness, I fully agree, I understand that. It is not big. 1000lm less evenly distributed over this area, it is not bright. A little brighter street lights and much dimmer than, say, a bright light near shopping centers or in Parking lots, illuminated by searchlights.
well, just a great review, thanks!

Yes, not even comparative. Just a photo on the road, though the fill view. These smooth ticks on the wall to watch them in lisovani optics is not difficult to obtain.
The fact of the matter is that no one gives comparative pictures with the xenon) And only signs)
Cool, of course. And very cheap, if you think the price of cheap xenon. But how they Shine, something impressive if you watch it on the road. The near boundary of the far and some strange shapes, but it's okay. In the center, I think they Shine much brighter than the sides.
They are sold in Russia already galogenu.net/catalog/svet...odnyy_modul_koito_bi_led/, probably just about six months. Only reviews I never found them. Understand that it's a copy, even with a similar diode as the original.
then strangely, Orlowski the ice was clearly designed as a relative replacement of the halogen. By the way the light shines on the lens, but the lower hemisphere userno cut off by a curtain, so shta in this regard
Perpendicular. Here is another photo, not mine, lens is different, but similar (Prado) yadi.sk/d/TSPKVNqnjzAip Optics from scratch was developed that is almost certain. Because the led hemisphere light, with bulbs the light need to gather in a circle. By the same light in all directions with the same brightness Shine, and the led — no. So here it's different, though the reflector can something similar. And that breadth is due to the fact that in the longitudinal direction focus needs rather than transverse. How many have seen the reports durbano LED headlight, it has become a well-established design. On the drive such reports now often began to appear.
it's cool, of course. By the way, judging by orlovskomu the led emitting surface which very closely follows the projection of the filament 1x4.1 mm, hike and change nothing, especially in optics was not necessary. the led module is parallel to the optical axis, or perpendicular?
Yes, you can just through a small resistance. I hitched directly to a 12V acid battery (from battery backup) current of 0.3 A was. Here is the biggest doubt I have is what max current can give. But if such svetice are on the Prado (one per side), 20W to digest, they should at least (1.5 amps). And the engine off, the size will be ))
At Moto network as elsewhere +/-13.8. So it is necessary to limit the current, you have to read more.
If the led is exactly this, the 13...14V and the current "taste" of 0.5 and probably up to 1 — 1.5 amps. At Mota on-Board power supply how many volt? Just under 12V neither here nor there, it turns out, we need the so-called buck-buck Converter (it, depending on the situation and lower the voltage and increase), and they are quite rare and exotic.
which driver it is necessary for them?
not hack them at all, and so there are a couple, wanted in vehicles to insert so lights I high, afraid of passing in traffic will disturb. I think Moto stick
Linear regulator 0.7 A.
Yeah, not too much brightness, but in and bask will not be much.
let me remind you that the regular comp boost buck! and this current step-down, i.e. at start-up, and a dead battery, the brightness will fall.

I looked today. Consistently.
Found the measurements above. Read. Do not understand. On the GX it turns out 2 LEDs are connected in series. Power 28 V, supply current of 1.15 A. Okay. It turns out the output power is equal to 28 V * 1.15 A = who's got a calculator, multiply. I got 32.2 per watt. It's what current limiting resistor should be put O_o ? 50 watts or something ? Of course you can hang parallel to the 2 W-wide resistors quantity 16 PCs. That's just the nominal value of help.
The power of one LED equals 28 divided in half, like 14 (we assume the crystals are identical).
Current consumption will be also equal to 1.15 A. the power consumption is equal to 16.1 watts. There are probably easier — can 2 W th dial (pieces 9).
IF we plug these beauties in parallel on the power supply Board, then we need a driver (I do not like is not a Russian word), capable of delivering A 1.15 * 2 = 2.3 A. But the power of such a driver is haunted.
Guys please help me. I even do not understand anything x)
PS: it is possible to conclude that Toyota ' s Lexus until 2016 with LED headlights and PTF have the same crystals. Computers control differ only in the magnitude of the output current. Probably they all have different numbers.
ZYZY: very interesting look inside the headlights of the new LX, NX, RX with six LEDs.

The problem:
have battered from Faro GX 460 2015. Paired lens is intact and judging from the appearance claims to be the best lens of the year.
you do not have — there is no electronic control unit LED, so-called HED LIGHT ECU costing hundreds of thousands of wooden.
Question — how to power the twin LEDs, provided that the LEDs are separate, not connected in parallel and apparently ate from the regular unit with two independent pairs of wires.
I understand that they are 14.5 is like death without a COMPUTER LIGHT CONTROL LED. By the way a strange thing, to be honest. Later the pictures will upload. The tablet is dead as always at the most inopportune moment. Charged — do photos.
I was tormented by the question of the choice of driver to replace the original. I would not want to buy the original.
Great. I skimmed through the comments below. In my case, it's just one led of the 4 consecutive crystals. As with all unfamiliar svatecni — connected adjustable PSU and raised the voltage until it glows begin, at the same time the current controlled. Well, on the bike powered through the boost Converter. Input 6...10 volts, at the output 12 (do not remember exactly). If that, specifically, these crystals can be directly powered from the 12V lead of the battery, the current would be about 250 300mA, not only from the vehicle with the engine running.

Driver any. The only reservation we have to ship it to two series-connected module, i.e., 28 volts, because on one module is too small the difference between output and input voltage, it may not like it. The price is not humane, of course, but particularly the mad not called to be.
Dima, Hello. Please tell me. How you powered your velofaru from the regular optics, not having the standard ECU ? Just 12 To put ?
Yes, there is a lot of bad. And the difference between the input and output of 2-4 volts. I.e. And increase in 2 times it will not survive.

Thanks for the measurements. Can I have them in the main text will include a link to you? Interestingly it turns out, the Highlander and the power IS twice lower. Most likely they have a bunch of lights already, that the brightness was the same. The driver I will check that.

Google "buck boost led driver"
It is not clear what he is, which increases or decreases, in any case, neither one nor the other type will not work. Similar to buck, in this case it is just voltage is not enough, it will not display the led at the desired current. Or home unit use, or simply through a resistor. Well or to look for a driver that will work with any voltage. If you have knowledgeable engineers on hand, just pick up a resistor at the desired current at the got engine and everything.

Ah, well then no questions. Use together with the native unit. Light should be enough. Unable to go outside, to Shine. I ohrenel when I first saw it as the beam walks in a neighboring yard across the street, it was 300mA,
Stunning !
The scoring turned out.
Actually I'm waiting when my tinsmith throw me scraps led lights )) Application to be found.
PS: spotlight on the New LX570 2016 is worth more than 500.000 R. )
People! It's just AWESOME! =)) I'm also mesmerizing with its light =))
If I had a bike — polyubasu equipped it would be a cool light and would ride only at night so that all ofigevali =))))
z.s. If no one has advised, here's superlight: same module on the frame ;) And such maddest slopes is not ;) And a twist beam with such a width is simply not needed, so he place on the frame ;)
probably the 10th time I re-read this article. Every time I find something new ))
Now the bike has undergone a sea change. All the light removed. Faro this slowly undone. Be quick, will stand in front of the fork crown mount to stock fork bottom (bottom in the stock drove another anchor, it will be screwed. But the frame is still not convenient. And strengthen uncomfortable and interfere with cables
