The radiator of LED street lamp adopts hollow honeycomb structure, which can form air convection at the upper and lower ends of the radiator, which increases its intensity and heat dissipation area, and improves the radiator capacity of LED street lamp. At the same time, the upper end face of the radiator is provided with a drainage channel to automatically discharge the rainwater.
The honeycomb radiator of LED street lamp and the installation box of current controller, the honeycomb radiator is composed of hollow heat sink in grid shape formed by one-time die-casting, the middle of the lower end face of the honeycomb radiator is fixedly provided with a mounting platform, the bottom end of the heat sink in the middle is closed, and the installation platform is fixedly connected with LED chip, LED The outer cover of the chip is provided with a lens, the cross section of the heat sink is hexagonal, and the inner wall of the heat sink is provided with a reinforcing rib. The side walls between the heat sinks in the middle part of the honeycomb radiator are conductive to form a plurality of drainage channels, and both ends of the drainage channels extend to the outside of the mounting platform respectively. The lower end of the honeycomb radiator is fixedly installed with a lamp shell. The hollow honeycomb structure can form air convection at the upper and lower ends of the radiator, increasing its strength and heat dissipation area. At the same time, the upper end face of the radiator is provided with a drainage channel to automatically discharge the rainwater. Compared with other radiators, the same heat dissipation area consumes less materials and has higher strength. Moreover, setting drainage lines solves the problem of dust accumulation.

High power LED works for a long time at a suitable temperature, so that the brightness of LED chip will not decrease due to overheating. High power LED honeycomb radiator can be used in all kinds of LED lighting sources, which can improve the heat dissipation effect by 60%, so as to better play the advantages of LED energy saving, low heat, no pollution, and so on, and obtain better economic and social benefits.
The honeycomb radiator is composed of a hollow heat sink in grid shape formed by one-time die-casting. The middle of the lower end face of the honeycomb radiator is fixedly provided with a mounting platform, which closes the bottom end of the radiator in the middle. The installation platform is fixedly connected with LED chips, and the outer cover of the LED chips is provided with a transparent mirror. The feature is that the cross section of the heat sink is hexagonal, and the inner wall of the heat sink is arranged There are stiffeners.
The honeycomb radiator is composed of a plurality of hollow heat sinks arranged in a grid. The side wall of the honeycomb radiator is fixedly installed with a current controller mounting box. The middle part of the lower end face of the honeycomb radiator is fixedly provided with a mounting platform. The bottom end of the heat sink in the middle is closed by the installation platform. The installation platform is fixedly connected with LED chips, and the lens is arranged on the outer cover of the LED chip The cross section of the heat sink is hexagonal, and the inner wall of the heat sink is provided with a reinforcing rib.
LED street lamp manufacturers use the hollow honeycomb structure, which can make the air convection at the upper and lower ends of the radiator, increasing its intensity and heat dissipation area. At the same time, the upper end face of the radiator is provided with a drainage channel to automatically drain the rainwater.
