The heat dissipation of LED purification lamps is also very important. The lamps with the same power factor and the same lamp quality, if the heat dissipation conditions are not good, the lamp works at high temperature, the light failure will be very large, and the life of the lamp will be reduced.
The relationship between heat dissipation material and LED purification lamp structure
At present, the main heat dissipation materials used in LED purification lamps are copper, aluminum and PC. The thermal conductivity of copper is better than that of aluminum, and the thermal conductivity of aluminum is better than that of PC. Composite ceilings typically feature a large portion of aluminum.
The best is inlaid aluminum, car aluminum (aluminum profile, extruded aluminum) second, the worst is cast aluminum, inlaid aluminum has the best thermal effect!
If the air convection method is used for heat dissipation, the insulation problem of the circuit and the power supply must be dealt with. Otherwise, LED purification lamps work in a relatively humid environment, which is prone to short circuits and safety accidents.
