Explosion-proof lamp cooling problem solution to extend life

 The manufacturer of the explosion-proof lamp knows that about 20% of the input power is converted to light and 80% is converted to heat for the light source LED, depending on a number of factors that may occur with the underlying aluminum module irregular and phonon emission, , The material, etc. When the LED starts to work, 90% of the total heat it generates is transmitted by conduction. To dissipate the heat from the LED junction, the conduction is the main channel of the heat conduction, because convection and radiation only account for all About 10% of heat transfer.

It is clear that the manufacturer of the explosion-proof lamp knows that the LED light source requires an accurate power and thermal management system because most of the power supplied to the light source is converted to heat compared to other light sources, and if there is no proper heat management, Affect the life and color output of the LED explosion-proof lamp, and because the LED drivers are silicon devices, they will soon fail, which means that a fail-safe backup overcurrent protection device must be provided to better use the explosion-proof lamp The protection.
