Engineers to talk about the heat dissipation problem of LED high bay light

Long lighting engineers were focused on three focus of LED high bay light : the luminous efficiency, power supply, heat dissipation problems, along with the advance of technology, these three questions are significantly improved.


Luminous efficiency due to the LED chip mainstream products on the market at present already more than 120 lm/W, more than 150 lm/W is just around the corner, on the one hand can make the same luminous flux but power is reduced, on the other hand, in terms of luminous efficiency can also reduce the heat generated by the same power of lamps and lanterns, the lower the cooling requirements, for the most common LED high bay light, due to the above two reasons, heat dissipation problems is still the important factors that affect the quality of LED high bay light and longevity.


LED high bay light as a kind of  has the potential to be bulk use energy-saving lamps and lanterns, be expected as well as  implied trap, and has repeatedly happened in LED high bay light light , is caused by the heat dissipation performance too bad lead to p-n junction temperature is exorbitant, makes the reputation of LED high bay light is damaged.
 

Although LED high bay light energy is converted to light more efficient, but most of the remaining energy in the form of heat accumulation, and the other will have more residual energy in the form of infrared divergent directly, and the LED chip p-n junction is sensitive to temperature, these makes the heat dissipation of high-power LED high bay light is very demanding.
