Solid-state lighting (SSL) differs from conventional lighting in that it uses light-emitting diodes (LEDs) instead of filaments, plasma, or gases. Although still relatively early in its development, ...

Just think, you could be in your bathroom at midnight and there could be an unexpected blackout. If the bathroom lamp relies only on grid power, think about what a scene that would be! A recent guest ...

Here is an economical way to experiment with light, color, and optics. You get one Red LED light source, one Green LED light source, and one Blue LED light source. The three LEDs can be controlled ...

Up until 1990, the standard headlight assembly contained only incandescent sources, mostly separate, to create all desired functions. Whether the functions were created by sealed beam lamps or bulb, ...

Light emitting diode (LED) lighting is becoming more and more popular, as incandescent lamps are being phased out globally. LEDs have several advantages over incandescent lamps, including energy ...

It's no secret that Light Emitting Diodes (LEDs) have taken over such segments of the lighting market as electronic displays and traffic signals. Now, LEDs are moving into general illumination. In the ...
