LED Cabinet Light Luminous principle
Jun 14, 2017

LED is a light-emitting diode is a solid-state semiconductor device, can be directly converted into light, the heart of the LED is a semiconductor chip, the chip at one end of a bracket, the other side is the cathode, the other end is connected to the power supply of the positive, so that the entire chip is encapsulated by epoxy resin

The semiconductor wafer is made up of two parts, part of the P-type semiconductor, in it the hole station dominates, the other end is the N-type semiconductor, on this side is mainly the electron, but these two kinds of semiconductors connect together, they form a pn knot directly, when the electric current through the conductor Action form sends the energy, this is the LED luminous principle.
