The invention provides a rear lamp body structure of a street lamp. The rear lamp body structure comprises a body, wherein a plurality of longitudinal fins are arranged at the front end of the body, and insertion holes for connecting an intermediate lamp body are formed among the longitudinal fins; a groove for mounting a street lamp support rod is formed in the center of the upper surface of the body, transverse fins are arranged on two sides of the groove transversally, and a fixing hole is formed in the groove; a power supply cavity for mounting a power supply is formed in the lower surface of the body; arc-shaped longitudinal fins are arranged at the tail part of the body. The rear lamp body structure provided by the invention has the advantages and the positive effects that a heat radiation structure of an LED substrate part is maintained; meanwhile, heat radiation is effectively performed against heat produced by the power supply; the body is integrally formed from ADC 12 die-cast aluminum. The rear lamp body structure is convenient to manufacture and environmentally friendly.
Description
technical field [0001] The invention belongs to the technical field of street lamps, in particular to a rear lamp body structure of a street lamp. Background technique [0002] Facing the serious shortage of electricity supply, energy saving is an urgent problem to be solved. Therefore, the development of new high-efficiency, energy-saving, long-life, high color rendering index, and environmentally friendly LED street lamps is of great significance to energy-saving urban lighting. [0003] In the existing technology, a heat dissipation structure is provided in the street lamp, which is generally aimed at the LED substrate and has a heat dissipation effect on the LED semiconductor device. A small fan is installed in the power supply part to dissipate heat or the effect of the heat sink is not good. Contents of the invention [0004] The problem to be solved by the present invention is to provide a rear lamp body structure of a street lamp. [0005] In order to solve the p...
