Also known as LED light-emitting chips, it is the core component of LED devices.Its main function is to convert electrical energy into light energy.The principle of illumination of the LED chip is: using the PN junction, the electrons in the N-type semiconductor and the holes in the P-type semiconductor are combined into photons (e-+h+=hv) at the junction interface, and the electric energy is realized.The conversion of light energy. | ![]() |
