explosion proof led lighting

With materials and packaging technology of explosion proof led lights continues to evolve, led explosion-proof lamp products to improve brightness. And the application of led explosion-proof lamp is more and more widely. Explosion proof light fixture as the backlight source of the display, is a hot topic recently. 

But the heat dissipation problem is in the explosion proof lighting developed as a major obstacle to lighting objects, the following text for you to introduce a number of heat dissipation methods and heat dissipation materials. Heat dissipation in general, in accordance with the heat removed from the radiator, you can divide the radiator into active heat dissipation and passive heat dissipation. 

The so-called passive heat dissipation of explosion proof led, refers to the heat source led through the thermal energy source of the natural radiation to the air, the effect of heat dissipation and heat sink is proportional to the size, but because it is naturally distributed heat, the effect of course greatly discounted.

Often used in devices that don’t require space, or for the heat of small parts, such as some popular motherboards on the North Bridge also take passive heat dissipation, the vast majority of the adoption of the active heat dissipation, the active cooling is through the fan and other heat dissipation devices forcibly removed heat from the heatsink, which is characterized by high heat dissipation, And the equipment is small in size. Active heat dissipation, from the cooling mode subdivision, can be divided into air-cooled cooling, liquid cooling, heat pipe cooling, semiconductor refrigeration, chemical refrigeration and so on. Wind cold cooling is the most common way to heat, compared to the cheaper way. 

Air cooling is essentially the use of fans to take away the heat absorbed by the radiator. It has the advantages of relatively low price and convenient installation. However, environmental dependence is higher, for example, when the temperature rises and the thermal performance of overclocking is greatly affected.
