2. LED has rich color display and good monochromaticity of emission light. This is due to the way LED chips produce light. By adopting different color material, different colors of monochromatic light can be produced. Applying yellow light fluorescent powder on the basis of blue light chips can get white light LED with different color temperature. Or encapsulating three monochromatic colors of red, green and blue LED chips into one LED can get mixed colors through optical design.3. LED Lights have a long life span and quick response which allows for frequent switching. High power led high bay can work for more than 50,000 hours in normal working conditions.
