Used in industrial, architectural, and automotive applications, as well as for warning lamps and emergency lights, high-brightness power LEDs (HBLEDs) are becoming more and more popular, due in part ...

LED output is a function of the current through it. So to drive the device, it would seem simple enough to set the LED current with a series power resistor. But there’s a problem with this idea. First ...

There is much interest in LED-based lighting due to the availability of high-power, high-efficiency white—and other-color—LEDs (Reference 1). Because an LED is a current-controlled device, typical ...

Scarcely a lighting application exists that designers have not considered converting to solid-state lighting, especially as LEDs by leaps and bounds improve both the quantity and the quality of their ...

As their production costs fall, LEDs are being used more often in applications ranging from handheld devices to automotive and architectural lighting. Their high reliability (operational lifetimes of ...
