In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

Adaptive brightness control has become a common feature in modern smartphones, HDTVs, PDAs, tablets, and computer screens. The goal of this feature is to conserve power as well as to make the display ...

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" ...

CCFL backlights are the most common backlight technology and are used in displays ranging from 5.7 to 23 in. or more diagonal. They can have from one to 24 or more lamps mounted along the edge of the ...

LEDs combine design flexibility with practical, robust circuitry, enabling automotive designers to produce striking headlight designs matched by exceptionally long life and performance. Automobile ...
