What is a light emitting diode (LED)? The application of LED light source in the field of lighting is the product of the rapid development of flat conductor luminescent material technology.
LEO (Light Emitting Diode) is a semiconductor light-emitting diode that uses solid semiconductor chips as light-emitting materials. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine and emit excess energy, which causes photon emission to produce visible light.
What is a light emitting diode (LED)? At present, the luminous efficiency of high-power LED can reach 30lm/w, the radiation color is diversified, and the life span can reach tens of thousands of hours.
The color of LED light is determined by the material that composes the semiconductor. Aluminum phosphide, gallium phosphide and indium phosphide alloys can be made into red, orange, and yellow; gallium nitride and indium nitride alloys can be made into green, blue and white.
What is a light emitting diode (LED)? Compared with the commonly used light sources, the light output of the LED is relatively low, so an array or other structure is required to form the illuminating lamp.
LED is a low-voltage power supply. It has the advantages of simple accessories, compact structure, good controllability, rich and pure colors, high bright spots, good moisture-proof and vibration-proof performance, energy-saving and environmental protection. At present, it plays a pivotal position in the field of display technology.
