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 ...
Machine-vision systems use very short flashes of intense light to produce high-speed images employed in a wide variety of data-processing applications. For instance, fast-moving conveyor belts are run ...
The growing demand for color displays in cell phones, digital cameras and PDAs has created a huge market for white LEDs as backlights in these applications. Because white LEDs require low dc voltage ...
[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" ...
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 ...
Ok, i have 8 3.6v (20mA) LEDs on a single 12v line with a 50 ohm resistor. My problem is that the amperage of all the LEDs exceeds 1W and my resistor is only a 1W. Could i make two sets of 50 ohm ...
