As the high power issue, the sink problem of Power LED high bay light is really a great problem, because the heat directly determine the life of the product, and the product life span and is related to the company’s reputation, good things do not go out, bad news travels, if the quantity order of Power LED high bay light meet with heat sink problems, it would be a bad news and joke throughout the world.
Every factory take a lot of cost on the heat sink system of Power LED high bay light, but still ineffective, as bulky, heavy, ugly appearance, if we can put some of the heat transfer to the shade, it would not only reduce the cost and weight, but also improve the cooling effect .
To get a good use of shade to heat, it must be addressed from the LED chip to the shade of the problem areas, the heat transfer interface must be less resistance from being able to small. Taking into account the cost advantage of COB, LED mining lamp future aluminum plate can be used in the form of COB, while aluminum substrate directly as LED mining lamp shade, heat transfer is at least one way interface, and the use of isolated power supply, safety too easy to pass, because even in case of plastic packaging current breakdown is less than 36V safety current.
Currently, ENELTEC says the best solution for the Power LED high bay light is micro capillary groove composite phase change cooling technologies. Small size and light weight. Thermal cooling effect. Principle is to use micro-channel structure able to pull the liquid heat transfer medium into a thin liquid film, light film heat to a thin liquid film, film vaporization take tremendous heat, steam radiator inside the confined space spread to radiator fins in contact with air, after cooling into a liquid heat transfer medium is recycled back to its original position.
