Description

High power LED high bay lamp based on vapor chamber

technical field

Background technique

LED (Light emitting diode) has the advantages of energy saving, environmental protection, long life, adjustable brightness and color temperature, and high color rendering. With the maturity of LED technology and the continuous improvement of efficiency, LED solid-state lighting is the trend and the best solution for energy saving. However, with the wide application of LED high bay lights and the need for lighting intensity, people have put forward higher requirements for their power. The power does not increase, making the heat dissipation enhancement of LED high bay lights a factor that must be considered to ensure the quality of its products. If the heat cannot be effectively conducted, it will seriously affect the service life of LED industrial and mining lamps. Therefore, the heat dissipation of the lamps has become an important issue. If the heat is not dissipated to the environment in time, the excessive temperature will burn the chip temperature, which will cause High bay lights are broken.

The COB light source has the characteristics of high integration and concentrated temperature, so it poses further challenges to thermal design. Due to the low electro-optical conversion efficiency of LED lamps during the lighting process, about 80% of the electric energy is converted into heat energy and concentrated on the chip. The LED chip is very sensitive to temperature. If the heat cannot be conducted in time and dissipated to the surrounding environment In the middle, it will affect the service life, luminous efficiency, luminous wavelength (color temperature), forward voltage, etc. of the LED. If the temperature is too high, it will even cause permanent damage to the LED. Therefore, the heat dissipation structure design of the LED is particularly important. Therefore, the problem of heat dissipation has become the main technical factor that limits the development of LEDs to high power and small size, and is the key to restricting the large-scale promotion of LEDs to commercial and civilian use.
