Tool free opening, button design on both sides, can open the shell by hand, the overall maintenance is convenient. Overall heat dissipation concept: more than 85% of the die-casting aluminum of this street lamp participates in heat dissipation, and the temperature difference of the whole main body is less than 6 °. The heat dissipation is strengthened to the maximum extent, effectively extending the life of the lamp. At the same time, the designed lamp also meets the concept of separating the light source cavity and the power supply cavity. The light source cavity and the power supply cavity will not interfere with each other. Smooth shell design, overall profile, high aluminum density, less air, good heat dissipation, no insulation layer. The light distribution technology adopts nano reflector, lens control light, control light reflection angle.Module design
