As the new emerging product in lighting, led high bay has a totally different lighting method from traditional lights. The electron hole recombination in PN of semiconductor can produce light. The different ways of lighting decide that LED Lights are essentially different with traditional lights, and also decide the uniqueness of LED lights.1. Smaller size. The size of single LED chip with high power is normally 1 square millimeter, so one LED is often several millimeters with encapsulation material. Multi-chips LED high bay integrates many LED chips, which makes it larger in size.
