Why does LED have a long life?

The illuminating mechanism of incandescent lamps is that electric energy heats and emits luminescent tungsten wires. After a long period of heating, the tungsten wires will age or even burn out. At this point, the life of incandescent bulbs ends, and the luminescence mechanism of LEDs ends. It is determined by the special composition of the diode. The diode is mainly composed of a PN crystal piece, an electrode and an optical system. When a forward bias is applied to the electrode, electrons and holes are injected into the P region and the N region, respectively. When the balance of minority carriers and majority carriers is balanced, excess energy is converted into light energy in the form of radiated photons. The illuminating process consists of three parts: carrier injection under forward bias, composite radiation, and light energy transmission. It can be seen that the diode is mainly illuminated by the continuous movement of carriers, and there is no aging and burning phenomenon. Its special illumination mechanism determines its luminous lifetime of up to 50,000-100,000 hours.
LED Lighting We must recognize that the concept of single or multiple white LEDs is different from the concept of a luminaire used as an illumination source. Up to now, white LEDs developed and produced at home and abroad are far from meeting the requirements of illumination sources. We should make use of our country's advantages and advanced technologies in developing various compact fluorescent lamps in the world, seize opportunities, and make a difference in the development of new solid-state light sources. Some of the major issues faced by LED luminaires in white light LEDs that implement lighting sources are similar to those that compact fluorescent lamps have faced or are addressing.
1. The AC-DC converter circuit installed in the luminaire should be adapted to the characteristics of LED current drive.
This power supply must have a forward current output close to constant current required for the LED, and a high conversion rate to ensure safe and reliable operation of the LED, of course, pay attention to cost.
2, LED lamp reliability
The factors affecting the reliability of the luminaire are mainly LED devices and the above-mentioned electrical components. The LED light source used by our company is a world-class manufacturer. The main components of electrical accessories are European and American manufacturers.
3, lamp cooling
The overheating of a single LED is not equal to the solution of the heat dissipation of the illumination source. With the development of high-power, large-size, high-brightness chips, the heat dissipation of LED devices and lamps must be solved. Our high-power LED lamps adopt self-developed radiators with patents for invention.
4. Uniformity and optical system of light color of lamps
Due to the special characteristics of small LEDs, the light characteristics are not like the incandescent bulbs and fluorescent lamps, and there is a problem of unevenness of white light color. What is the uniformity of light color after synthesizing lighting fixtures? The light distribution of the "secondary light source" composed of several LEDs and how the optical system constituting the LED luminaire meets the requirements of the illumination source is a complicated system engineering, which needs to be seriously considered and solved.
