Heat Dissipation Performance Of Led Explosion-Proof Lamp
Writer：Jane Time：2021-07-20 Browse：192 The quality of LED explosion-proof lamp is mainly determined by its heat dissipation performance, and also depends on its heat dissipation material, which determines its service life. Heat dissipation is one of the main factors affecting the illumination intensity of LED lamps. LED lighting tools are 80 percent more efficient than traditional incandescent bulbs, but their components and driver circuitry dissipate a lot of heat. If this heat is not properly discharged, the luminosity and life of LED lighting fixtures will decrease dramatically.
There are several general cooling methods:
Liquid cooling heat dissipation, heat pipe heat dissipation, semiconductor refrigeration heat dissipation, chemical refrigeration heat dissipation.
And its heat dissipation materials are especially important, there are generally three kinds of heat dissipation materials:
Pure aluminum radiator, pure copper radiator, copper aluminum combined radiator.
To improve the luminous efficiency and service life, solve the problem of products is one of the most important topic of present price segment, the development of LED industry also is the high power, high brightness, small size for its development key, therefore has its high heat resistance, precision size heat dissipation base board, also become the development trend of the future in LED heat dissipation substrate.
It makes use of the characteristics of low calorific value of LED explosion-proof lamp to achieve intrinsically safe explosion-proof level, and the life of LED light source is long; The LED remains constant at the end of the battery charge and discharge point; The heat dissipation device on the lamp shell can realize the effective heat dissipation of LED module and ensure the use stability. It is suitable for lighting in various industries such as coal mine, oil, railway, flood control and so on.
