Outdoor LED lamps should pay attention to matters in the selection of heat dissipation materials

Use aluminum or aluminum alloy with good thermal conductivity, copper or copper alloy, and other alloys.

Research on radiator design of outdoor LED lamps

1, clear LED lights need to heat the power.

2, the use of loose type. Cost comparison: natural convection heat dissipation cost is the lowest, strong wind cooling medium, heat pipe heat dissipation cost is higher, jet cooling cost is the highest.

3. Design radiator parameters: thermal conductivity of metal, chip, radiator, thermal resistance of ambient air, etc.

4. Calculate the volume, area and shape of the radiator.

5, in the room temperature of 39℃ -40℃ environment, whether the temperature of the lamp meets the heat dissipation requirements, if not, then recalculate and adjust.

6, determine the maximum allowable working temperature of LED lamps (ambient temperature plus lamp allowable temperature rise).

7, do waterproof, dustproof, anti-aging, stainless steel bolt fastening, and then refer to the latest outdoor lighting technical specifications issued in China, as well as urban road lighting design standards.
