White LEDs used in backlighting provide illumination for the pixels in liquid crystal displays. The LEDs are typically routed on one or two sides of the displays light diffuser, and biased with 20 mA ...
[Tim] recently found himself tinkering with a cheap string of LEDs. Far from an advanced, IC-controlled addressable set, these were merely a string with LEDs of four colors that could be switched on ...
High-power industrial Light Emitting Diode (LED) fixtures use series-parallel strings of High Brightness (HB) LEDs to produce superior lighting fixtures compared to traditional, "ballast-based" ...

I thought I had this all figured out, but I need some urgent help. I need to power 52 LEDs for a project I'm working on, and I thought I could use a 12V, 7A lead-acid RC car battery. So, I soldered 3 ...
I picked up six new triple red LED fans from Xoxide and they arrived today. My plan is to revamp all of the cooling in my case with these new fans, but I want to modify the fans to be able to switch ...
The traditional way to control the output of multiple LEDs is to dedicate a pulse width modulation (PWM) controller to each LED and use the controller to transform the input voltage to a current that ...
The shift from 2G to 3G has turned cell phones into multimedia devices with built-in cameras, Web browsers, games and personal digital assistants (PDAs). This, in turn, has introduced color displays ...
