LED heat dissipation
5/1/2020 5:08:35 AM

Everyone knows that LED lamps have many advantages over traditional lighting fixtures, but a big problem of LEDs is heat dissipation. Whether the heat dissipation problem is solved perfectly is directly related to the quality of a lamp, so do the heat dissipation. The solution is critical to the quality of the LED.

       The application of heat dissipation materials in the LED lamp housing industry should not only focus on the heat dissipation coefficient, but neglect the thermal resistance value. If you only see a certain kind of heat dissipation patch, heat dissipation paste, heat dissipation paint or heat conductive adhesive film with a good heat dissipation coefficient, you can think that you can conduct high heat out, which may be disappointing. Therefore, it is expected that the temperature will drop, the LED lamp housing will not be decayed due to overheating, the life of the street lamp can be effectively extended, and the smooth acceptance of the inspection may not occur.

LED lamps are composed of housing, heat dissipation structure, driver and lens, so heat dissipation of LED lamps is an important part. Whether the LED lamp is stable, the quality of the lamp and the heat dissipation of the lamp body are important. At present, the heat dissipation of high-brightness LED lamps on the market usually uses natural heat dissipation, which is not ideal. If the heat dissipation is not ideal, the life of the lamp itself will also be affected. To protect the lamps and lanterns from the erosion of the climate environment, the heat is effectively conducted out, and the cost-effective and effective method is to spray soft ceramic cooling paint. Only from the perspective of overall heat dissipation and reducing thermal resistance interference is the key to the acceptance of LED lamps and large lamps. The protective shell of the lamp should abandon the traditional electroplating or baking paint, these two construction methods will seal the heat back into the lamp.

       Therefore, each manufacturer must actively invest in manpower to develop a better heat dissipation solution, so that the quality of LED lamps continues to improve.
