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.
Relationship between heat dissipation materials and structure of LED purification lamps
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, aluminum for cars (aluminum profiles, extruded aluminum) is the second, the worst is cast aluminum, and the thermal effect of inlaid aluminum is the best!
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.
