The causes of heat and heat dissipation of LED high bay light
Causes of heat generated by LED light source:
The light source of LED high bay light is the same as traditional light source, LED semiconductor luminescent diodes will generate heat during the working period, depending on the overall luminous efficiency.
Under the effect of external electrical energy, the radiative recombination of electrons and holes in electroluminescent, radiate near the p-n junction of light to pass through the chip itself and encapsulating semiconductor media medium to reach outside air current injection efficiency, radiation light quantum efficiency, chip external light extraction efficiency, etc., in the end is only about 30%-40% of input electric energy into light energy, the other 60-70% of the energy is mainly to the radiative recombination occurs in the form of lattice vibration into heat energy.
In addition, the increase of chip temperature will enhance the non-radiation compound and further weaken the luminous efficiency.
Because, people felt subjectively high-power LED high bay light no heat, in fact there are a lot of heat, so that the problems in use process, plus a lot of people who first use high power LED high bay light, the thermal dissipation and don't know how to effectively solve, make product reliability become major problems.
Methods of heat dissipation of LED high bay lights:
The first: conventional heat dissipation, the conventional way is to use the thermal conductivity we often use to heat the LED high bay light. However, as it is used in normal thermal conductivity, the thermal conductivity is generally the same, and this LED lamp heat dissipation method is not so effective.
The second kind: liquid thermal conduction, which is a kind of heat dissipation method that is not long studied by a semiconductor research institute in guangdong province.This method has a great contribution to solving the heat dissipation problem of large power small volume.
The third kind: heat pipe heat dissipation method, this kind of heat tube gives LED high bay light heat dissipation the way is similar to our computer CPU heat dissipation.But the size of LED high bay light would be larger.
TEK LED high bay light adopts HDT process, and the heat pipe has zero distance contact with heat source.
The pure copper heat pipe has zero distance contact heat source, and the heat conduction of the light source can be transmitted to the radiator body rapidly, and the heat transfer speed is 200 times that of the aluminum radiator.
