LED is a diode that converts electrical energy into light. It is a semiconductor solid light-emitting device, commonly known as light-emitting diode. It uses solid semiconductor chips as light-emitting materials. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine and cause photons. Emitted to produce light.
Divided by power: high power refers to products with higher luminous intensity: such as LED tubes, LED strips, LED lamps, etc.; low power refers to products with lower luminous intensity: LED induction lights, LED cabinet lights, LED corn lights, etc. ;
According to the packaging method: DIP and SMT;
LED can directly emit red, yellow, blue, green, cyan, orange, purple, and white light.
The brightness of the led is measured in lumens, and the brightness is the density of light intensity, that is, the brightness of the light source perceived by the human eye.
LED is known as the fourth-generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long life, and small size. It is widely used in various indications, displays, decorations, backlight sources, general lighting and urban night scenes. According to the different functions, it can be divided into five categories: information display, signal light, car lamps, LCD backlight, and general lighting.
