So, what does the little indicator light on your cell phone, a street light, an exit sign, and the common household light bulb have in common? If your answer is that light emitting diode (LED) technology can power all these things, then you're pretty bright.
LEDs are a form of
solid state lighting. Once the
new kid on the block, LEDs have emerged as one of today's most energy-efficient and rapidly growing technologies. There are a wide variety of
LED products available in the market, with the technology found in automobiles, computers, televisions,
recessed downlights in the kitchen, flashlights, and holiday lights.
LEDs are different than other types of lighting in that they last longer, are more durable, and save more energy and money. They also emit almost no heat. By comparison, inefficient incandescent lighting gives off 90% of their energy as heat.
