Lighting principle of led tri-proof light
LED tri-proof lamp bead ultra-fine particle structure This chip structure is quite complicated, and it is divided into several layers: the top is called the P-type semiconductor layer, and the middle layer is the light-emitting layer.
After enlarging the structure of the LED tri-proof lamp bead, you will find a chip shaped like a sesame seed.
LED tri-proof lamp beads ultra-fine particle structure
The structure of this wafer is quite complicated and is divided into several layers: the top layer is called the P-type semiconductor layer, the middle layer is the light-emitting layer, and the lower layer is called the N-type semiconductor layer.
So, how is the LED tri-proof light emitted?
Lighting principle
From the perspective of physics: when the current flows through the wafer, the electronic devices in the N-type semiconductor and the cavitation in the P-type semiconductor violently collide and recombine in the light-emitting layer, resulting in photons, which emit kinetic energy in the form of photons (that is, everyone sees of light).

LEDs are also called light-emitting diodes, which are small and fragile, and are not convenient for direct use. Therefore, the designer added a maintenance shell to it and kept it inside, which constitutes an easy-to-use LED lamp bead.
After a lot of LED lamp beads are connected together, a variety of LED tri-proof lights can be formed.
