The term LED is an acronym for Light Emitting Diode, a light source that generates photons from the movement of electrons that recombine with electron holes when an electrical current is passed through through a semiconductor material that contains a specific type of p-n junction.
In this article, we have summarized and characterized the suppliers of LED lighting technology in two distinct sets of companies. The first group represents manufacturers of LED chips, the semiconductor devices themselves. The second group represents manufacturers of packaging, which is defined here to be the housings or other assemblies which hold the semiconductor LEDs, provide associated electrical input wiring or harnesses, and include any needed mounting connections. Lastly, the article includes summaries of LED Lighting manufacturers who sell finished lighting units either wholesale or retails to businesses or consumers.
LED Chip Manufacturers, USA and Global
These global companies manufacture LED chips that enable control of LED lighting. Current flows through the chip, emitting light. The chips can be bonded directly to the substrate within the LED bulb so that the bulb is referred to as a chip-on-board (COB) LED. LED chips enable the management of luminosity, brightness, color, and lifetime for applications on roadways, parking areas, and indoors.
