Taking into account the heat dissipation and IP protection of LEDs in road lamps, the more reasonable design guidelines are:

a. In the critical heat dissipation position, a heat conducting plate is used. The heat conducting plate is inside the metal plate, and is uniformly provided with a thin pipe for the refrigerant to flow, and the cooling pipe is filled with the refrigerant. When a certain part of the heat conducting plate is heated, the refrigerant in the thin pipe flows quickly to make the heat rapid. Ground conduction. The heat transfer coefficient of a good heat-conducting plate can reach 8 to 12 times that of a copper plate of the same thickness. Although the price is high, if it is used in a key part, the heat dissipation of the LED will have a multiplier effect.

b. Design the outer casing of the luminaire into a radiator. Most of the road lamp housings are made of aluminum. Directly using the outside of the lamp housing as a heat sink can guarantee the IP protection level and a large heat dissipation area. In addition, when the radiator of the lamp housing is dusty, It can be flushed by natural wind and rain to ensure the continuous effectiveness of the heat sink.
