DRL in the high beam lights IVECO
this time the headlights do running lights.

materials:
aluminium foil
the samsung 3535 LEDs 1 watt power. 7x2 14 pieces
linear drivers from ON-semi 2 Grand
NSI50350AST3G in the case of SMC. it dvuhfasadnye chip.
in this arrangement convenient is that upon heating the chip cuts power by reducing capacity. this prevents thermal runaway of the LEDs.
file signets for those who will want to repeat
Through a search engine look for. They have a lot of sells. just copy the name mikruhi.

sveicam it won't be hot ? Yes, and NSI are heated normally is.
Checked glued in the reflector lights, heat, now about 35 degrees)))
With this chip with the power supply of passenger cars, consistently can 3 led. Well, or a good and powerful four. It all depends on the voltage drop...

All will be well. Mykruha when heated, cuts power by reducing capacity. Board is glued in the metal reflector on the table for an hour of work the Board is warmed up to 65 degrees
Sorry for the stupid question, but for 12V you need twice the LEDs?
These boards were designed so that the secondary optics could deliver. It still would be interesting
At exactly. someone fighting for the light and someone (in the next topic) toned rear lights :-)
What kind of diodes are?
Of course useful. A remake is never too late. And the extra 100 lumens is better than the extra 3-4 degrees cooler.
Such thoughts came to mind, but I decided to see how long they'll last, I'm done waiting. And decided for themselves that this thing is certainly good and useful.
had not 6, but 7 to do. Then it would be another watt of heat turned into light flow, not heat ))
Know it. Just when they did, did not expect that they have so much warm heart. Though like nourish Shine 6 watt 24 volt. But I commend the system works for a year every day for 12 hours and up to.
It is a linear driver. He will warm up, dissipating the excess voltage in heat, just need to pick up customers so that as little tension was too much )))
well if so.
I'm just the mother did lights for colors with the same microgame, so they are even with the radiator heated

welcome Radik. time left 2 days. got to hand to the manufacture of circuit boards. soldering just a couple of days. (I was waiting for ICS NSI) about the tracks I know, but thanks anyway =) did so because the Board is painted, and tin I didn't like this volume. alloy rose after cooling still after a while it becomes a bit dull. I don't like it. especially because the glass on the headlight is completely transparent. specifically, this charge I was lutil POS61 because it has a higher melting point. and headlight initially expected hot. so I decided not to risk it. about collimating lenses agree with them would be interesting. I offered and even showed the owner how it will look in the spotlight. but. alas. he didn't want to. truck IVECO, specifically what I do not know. as the headlights are assembled and installed on the car(waiting for one glass of the headlamp) I will take pictures and videos during the day . solution blue is neccersarily ammonium(ammonium persulfate) as copper played off a lot on the second card began to fall out of crystals to speed up the process, I acidified it slightly. used citric acid. it gave the green color of the solution =)
Alexey, good afternoon. You have tried on glory. Tell me honestly how it took man-hours? ))) I have a couple of tips:
1. If the Board leave not only tracks but also the remaining area of copper, which is not used, the first Board is etched faster, second after tinning Board looks worse than a Board covered with a mask (when I'm tinning the excess alloy rose off a rough cloth — remains a thin layer like a mirror), and thirdly the copper to remove heat, especially if with the copper jumpers to connect the thermal-pads. (usually they are electrically neutral.)
2. So the machine is really noticeable still need to put the collimator at 5 degrees. These collimators (those 5 degrees) allow other parties to see the car with DRL for 500-600 meters. (At the present rate 500m — a few seconds). I know from my own experience: Thugs on the opposite lane do not go on overtaking. Pedestrians and especially cyclists no desire to suddenly pop up on the road. This narrow light does not cause discomfort to oncoming traffic at close distance of 10 meters — because it shines with a diameter of only 1 m and usually the driver's eyes are above the oncoming lane. DRL will only be visible in the distance, and from a distance they are not blind.
Now the questions: what case? On Ayveko such PTF? and what is the solution for etching the blue color?
All right, the chain of successive and that the led is burned out in such a configuration, it is necessary to apply more than 50 volts
I noticed what I thought? chain consistent. Burn out one diode and the whole headlight will go out. and look for candles how to solder.
short circuit
so, hint, curious zhezh :=)
I used aluminium foil. LEDs and a chip to the overall thermal circuit. Read the Datasheet on mikruhu. More precisely a graph of the temperature-current stabilization. I think it will be clear. Board and glued to a metal reflector. He is also a radiator.
It is good that it is not visible. So there is something to think about, to understand my whole plan
saw cooling of LEDs
2-lead driver is a current regulator. Him "below the belt" on the led temperature.

You eat on the highway 100km/h and to meet you too going at the speed of 100km/h. total convergence at a speed of 200 km/h, that is 55 meters per second. At what distance he needs to see you to have time to complete the overtaking in the opposite direction? Of 300-400 meters ?
on the track in the SDA is not required middle?
Truth is one: what would the pedestrian could see the car...and at night you can turn them off.
We're all going to knowledge grow. )) let him write it his right. Moreover, some knowledge of the DRL's he has. Any text an invaluable and necessary, and in a dispute born truth. Thanks for your post

I don't eat on the road. Especially with such speed) I will take pictures and everything will be clear. By the way, the lenses I suggested to the owner. It gave this option.
Don't answer him anymore. Good job. A lot of talk and write, those who a little that a hands are doing.I think that he is a typical Troll...
Besides ezdakov on the road enough to go more than 100 kmh/h. Brightness of 460 Lumens not only OSRAM, a colleague indulges in dimensions www.drive2.ru/b/2083763/
Lamp is 21 watts and has brightness of 469 Lumens, just cap the other. It's a warning light, they have the same brightness regardless of the manufacturer.

Bulb 21 watts of power and 500 lumens? I very much doubt

I know how to measure the angle. I recommend to perform the same actions with VAZ DRL. Well or for example with DRL Solaris. There is no angle of 30 degrees. And do not close.
Shine a light on the wall from a distance of 1 meter, measure the spot diameter. So how do you the distance to the wall is known, you can calculate the angle.
In my version of glass has the shape of a lens. The light is going. The LEDs are not too small set. Angle them though 115 degrees, but they work as it should.
On the Vase OSRAM? Angle of 30 degrees in normal DRL strongly doubt. My option luminous flux higher by almost 2 times
Watch catalog OSRAM, specifications, 460 Lumens standard
www.osram.ru/osram_ru/pro..._ru&productId=ZMP_1285824
From Grants this right, lamp 450-500 Lumens. The angle not more than 30 degrees.
Try to apply your rule for lamps with base p21w they are used in normal DRL for LADA family which are certified.

I was saying that in addition to the angles, there are other Requirements for DRLs. And my craft with 100% certainty can claim that title.
500 Lumens at an angle of 30 degrees will give 400 Candela. You have 120 degree, minimum standards need 2000 Lumens each.
From a distance of 50 meters all will be clear on any photo. You Just need to turn the dim lights on for comparison
When photographing it all depends on the sensitivity matrix and camera settings, that is, the photograph is useless. Trust only the numbers of the devices.
I understand you perfectly. The car will be back from the flight and I will take pictures from a distance. To dot the "And"
There are requirements on luminous intensity 400 to 800 Candela. If 900 Lumens at 30 degrees give 800 Candela. then at 60 degrees, you will need 1800 Lumens. If nearby, your home will be similar to the distant light that shines in all directions. I am constantly working on this and have seen a lot of homemade products.

Planned and about the grant to write, the neighbors recently bought Grant and Datsun. Left to negotiate, to give light to play and compete.
Thank you for your comment. Try something. Write about the regular DRL LADA Granta for example, what are they ? Yeah. I hope I was clear with my analogy.
At the angle of the LEDs is 120 degrees, it's not the DRL. Have running lights, the angle of 30 degrees is shining, like a flashlight. About the imbalance between the diys had to write a whole article to Select DRL on rules
