I just replaced a friends laptop LCD screen and it has an LED backlight instead of the neon tube type backlight. I decided to disassemble the screen to pull out the LEDs to see what size they are and if I could probably use them in something else. They are the flat bright kind, and I'm thinking about rearranging them into a square pattern and putting them behind my dome light. I can't seem to find the voltage online, and I don't want to risk blowing them by guessing. I thought about wiring them into a radioshack universal power adapter that I cut the tip of a long time ago, that way I can slowly increase the voltage until they come on. But I still won't know the exact voltage they were made for.
Does anyone know what voltage they are supposed to be? Or at least approximately. -------------------- -Jay

Ah I see, the trackpad and wrist rest of your Asus look just like the newer Satellite Pro series.
Yes, you can just cut the tracks and peel them off and then solder them onto something. There are no pins on the underside of these LEDs, they are SMDs. That stands for Surface Mount Devices. What "dome light" are you hoping to solder them into? [edit] Just googled that, apparently it's an uncommon term (in the UK, anyway) for the interior cabin light in a vehicle... well for that there are other options apart from opening up more screens or bothering with desoldering and resoldering all those LEDs from the backlight strips - how about an LED conversion kit for it from ebay? They're not that expensive and come in a range of sizes: http://www.ebay.co.uk/itm/Car-Interior-Lig...4-/230465463415 This post has been edited by Unicorn: Sep 20, 2011 - 9:50 AM |
