What is Solid State Lighting?
Solid state lighting (SSL) is lighting which relies on semiconductors to turn electricity into light. Some examples of solid state lighting include light emitting diodes (LEDs), along with polymer light emitting diodes and organic light emitting diodes. This type of lighting is much more energy efficient than other lighting systems, and it has a number of advantages, ranging from the quality of the light to safety. Several manufacturers specialize in producing solid state lighting and components. Prior to the development of solid state lighting, people use things like filaments, plasma, and gas to create light. When solid state components were initially introduced, there was minimal interest, but as the technology developed in the late 20th century, the implications and potentials of solid state lighting were realized, and the industry exploded. From being used as indicator lights and in other menial positions, LEDs started to be employed in a wide variety of applications, supplanting
Todays lamps are predominantly incandescent light bulbs and fluorescent tubes. For radios and TVs semiconductor electronics has long ago replaced vacuum tubes – for lighting the replacement of glas tubes by semiconductors has not been possible until recent breakthroughs in semiconductor technology in the 1990s. Solid state lighting uses GaN based light emitting diodes (LEDs) or organic light emitting diodes (OLEDs) as lamps.
