The radiator of LED street lamp adopts a hollow honeycomb structure, which can make the air convection at the upper and lower ends of the radiator, increase its strength and heat dissipation area, and improve the radiator capacity of LED street lamp. At the same time, the upper end of the radiator is equipped with a drainage channel to automatically discharge rainwater.

Honeycomb radiator and current controller installation box for LED street lamps. The honeycomb radiator is China LED pole top luminaires factory, which is composed of a grid shaped hollow radiator formed by one time die casting. The middle part of the lower end surface of the honeycomb radiator is fixedly provided with a mounting platform, which closes the bottom end of the radiator in the middle part. The mounting platform is fixedly connected with LED chips, and the LED chips are covered with lenses, The cross section of the heat sink is hexagonal, and the inner wall of the heat sink is provided with reinforcing ribs. The side walls between the radiating fins in the middle of the honeycomb radiator are conductive to form a plurality of drainage channels, and both ends of the drainage channels are respectively extended to the outside of the mounting platform. The lower end of the honeycomb radiator is fixedly provided with a lamp housing. The hollow honeycomb structure is adopted to enable air to form air convection at the upper and lower ends of the radiator, which increases its strength and heat dissipation area. At the same time, the upper end of the radiator is provided with a drainage channel to automatically discharge rainwater. Compared with other radiators, the same heat dissipation area consumes less materials and has higher strength, and the drainage line is set to solve the problem of dust accumulation.

High power LED works for a long time at a suitable temperature, so that the brightness of the LED chip will not drop due to overheating. The high-power LED honeycomb radiator can be used for various LED lighting sources, and can improve the heat dissipation effect by up to 60%, so as to better play the advantages of China Wholesale LED pole top luminaires, such as energy saving, low heat, and pollution-free, and achieve good economic and social benefits.

The honeycomb radiator is composed of a grid shaped hollow radiator formed by one time die casting. The middle part of the lower end surface of the honeycomb radiator is fixedly provided with a mounting platform, which closes the bottom end of the radiator located in the middle part. The mounting platform is fixedly connected with LED chips, and the LED chip is covered with a transparent mirror, which is characterized in that the cross section of the radiator is hexagonal, and the inner wall of the radiator is provided with reinforcing ribs.
