Why Does LED High Bay Generate Heat Energy?

Time:2017/2/23  keywords:LED High Bay, LED High Bay Light


      Like traditional light source,  led high bay   also gives out heat during working, whose quantity depends on the whole luminous efficiency. Under the effect of external electric energy, electron and cavitation radiation compound to cause glow and was released through semiconductor medium of chip and package medium. Integrated the efficiency of current injection, radiation light quantum and chip’s release light, finally about 30-40% output electric energy is converted into light energy, while the rest 60-70% energy is converted into heat energy.


LED High Bay.jpgAs the increase of chip temperate, non-radiative recombination would enhance, which further weakens luminous efficiency. People subjectively think that big power LED has no heat energy, but it is not the case. Many people use LED High Bay Light at the first time and don’t know how to solve the problem of heat or even doubt the reliability of product.


So why does LED High Bay generate heat? How much energy could it generate? The answer is yes. When LED in positive voltage, electron gains energy from power. Due to the driving of electric field, these electrons compound with cavitation and give out heat. Fixture is able to glow just because of the releasing energy, so does heat energy. Thus it can be seen that heat energy is not supplied by power. As for the number of power, it is depends on the material and doesn’t matter with external electric field.
