The most essential component of any LED light bulb is its LED chip. Think of it as a computer chip that holds all the data and knowledge of the computer, it is the place where all the action happens. If you didn't know already, LED stands for light-emitting diode. A diode is a two-way electronic component that emits light by allowing an electrical current to flow throughout the light bulb. The heart of an LED chip is a semiconductor chip, one end of the chip is attached to the negative side of the holder, and the other end is connected to the positive side of the power supply, and the whole chip is encapsulated by epoxy resin. With that being said, let us find out which brands belong to the top global LED chip manufacturers!
 
1. CREE:
A very famous LED chip manufacturer, a United States corporation, their products are often based on silicon carbide, gallium nitride, silicon and related compounds, capable of manufacturing blue, green, ultraviolet light-emitting diodes, near-ultraviolet laser, radiofrequency and microwave devices, power-switching devices and silicon carbide epitaxial wafers for production and research use.
