NeoFuture Posted April 20, 2009 Share Posted April 20, 2009 http://www.internetwork.org.uk/ledrear/side.jpg you cant do that with LED bulbs im not really keen on that look anyway so ill stick to LED replacements in the stock lights. Quote Link to comment Share on other sites More sharing options...

SteveR Posted April 20, 2009 Share Posted April 20, 2009 makes it quite difficult when cutting them out... Far play, I thought there would be a reason. Quote Link to comment Share on other sites More sharing options...
NeoFuture Posted April 20, 2009 Share Posted April 20, 2009 oh not knocking them, they are to many peoples tastes im sure, just not really mine, ill take a dash kit tho if you have one lol, they just seem like a lot of work to me Quote Link to comment Share on other sites More sharing options...

NeoFuture Posted April 20, 2009 Share Posted April 20, 2009 oh im not knocking you heckler i do think they look ok, not to my taste as i say, i just consider it a lot of work to design and build that kinda light, i just wish i had the time to do something like that myself i respect your tallent to pull it off and make them work and look that good, as i say, i only asked the question.

Digsy Posted April 21, 2009 Share Posted April 21, 2009 Hi Heckler I may have asked you his in the past, but I can't remember the answer. What output LEDs are you using? I made some LED lights for my house a couple of years back. Each lamp uses 15 LEDs in the 20,000mcd range, each drawing about 35mA with between 2 and 3Vf. When I powered them up I was surprised that I could feel a small amount of heat coming off them if I put my hand about 1 inch above the lamps. Until that point I had assmed that LEDs ran virtually cold. I have since learned that if you put many LEDs together, or use the really high brightness ones then heatsinking can become an issue. I guess you are using pretty high brightness ones yourself. Have you experienced any problems with heat mangement? Drilling all those holes in the PCB must be fun Quote Link to comment Share on other sites More sharing options...

Drilling all those holes in the PCB must be fun Hey chap, The reverse LEDs are 30000mcd, brake/fog/side light are 18000mcd and the indicators are 6000mcd. I've had no heat issues as of yet with the LEDs, but then again I don't think there on long enough to generate alot of heat. I think if they did produce heat, it wouldn't be as much as a 21w bulb! The only thing that does get hot, is the load resistor for the indicators. I really hate drilling the holes! But needs to be done Quote Link to comment Share on other sites More sharing options...
Digsy Posted April 21, 2009 Share Posted April 21, 2009 I was thinking less of the actual heat output by the whole unit (which you're right will be negligible compared to be 21W bulb), and more of the heat that can be tolerated by the LEDs themselves. I've been thinking about swapping out the less bright LEDs (purchased from eBay) in my lounge for these ones from Rapid Electronics. They have similar voltage / current requirements but are about 50% brighter. Looking at the design, they have an enlarged cathode which acts as a heatsink. I'd like to see the datasheet for these to see if they need to be solered to an extra large track on the circuitboard to helkp channel the heat away. http://www.rapidonline.com/Electronic-Components/Optoelectronics/5mm-LEDs/5mm-Ultra-high-brightness-15-deg-LEDs/73421 Quote Link to comment Share on other sites More sharing options...

tony tt Posted April 21, 2009 Share Posted April 21, 2009 Ive seen the work heckler puts into these things first hand days on end doing one light literaly!. He has the true patience of a saint and they will look very individual. I got my dash done by him in the blue l.e.d,s and its very cool.

heckler Posted April 22, 2009 Author Share Posted April 22, 2009 Well, no major updates today, only thing I've had time to do is mark out on the PCB's where to cut as if anyone else has ever noticed that the lenses are not circular! The should be cut to shape tommorow, and possibly start etching aswell. - who knows may be able to start soldering at the weekend! Quote Link to comment Share on other sites More sharing options...

heckler Posted April 24, 2009 Author Share Posted April 24, 2009 (edited) Right, update 1 for today, PCB all cut out, just put in the etching bath.. not much to look at I know... http://www.internetwork.org.uk/lights/cut.jpg Edited April 28, 2009 by heckler (see edit history) Quote Link to comment Share on other sites More sharing options...

heckler Posted April 24, 2009 Author Share Posted April 24, 2009 (edited) right, next updates Just been in the etching bath, which gives this: http://www.internetwork.org.uk/lights/etch1.jpg now, this leaves the mask still on the copper, so using brillo pads.. http://www.internetwork.org.uk/lights/etch2.jpg Next step is painting - but that for tommorow Edited April 28, 2009 by heckler (see edit history) Quote Link to comment Share on other sites More sharing options...
