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. |  |
