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 ...

LEDs are finding their way into more products than ever before. Automotive lighting, TV backlights and tablets are just a few applications that require multiple LEDs. Driving a large number of LEDs ...

iWatt has launched the industry's first dc/dc led backlight driver to power up to 32 parallel strings of leds for direct and segment edge led tv backlighting. The mixed signal iW7032 IC features iWatt ...

National Semiconductor has introduced a chip for balancing current in parallel strings of lighting LEDs. Applications are expected in street lights and other high power luminairs. “Without balancing, ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

Cree LED has added higher efficiency high colour rendering index versions to its XHP35.2 leds, and introduced leds optimised to dim evenly when used in parallel The company has used its latest ...

[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 ...

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 ...
