LED light products industry introduction

1.1 Basic Concepts and Lighting Principles of LEDs

LED is a semiconductor device that can convert electrical energy into light energy. The core part is a chip composed of a P-type semiconductor and an N-type semiconductor. There is a PN junction between the P-type semiconductor and the N-type semiconductor. When the injected minority carrier is combined with the majority carrier, excess energy is added. Released in the form of light to convert electrical energy into light energy. Chips of different materials can emit light of different colors such as red, orange, yellow, green, blue, and purple, and "light-emitting diodes" are also named after them.

1.2 advantages of LED light source

Compared with traditional light sources, LED light sources have many advantages such as energy saving, environmental protection, safety, robustness, small size, long life, short response time, and rich colors. See the table below for details:
