High-efficiency street lamp heat-radiating structure

Abstract

The invention discloses a high-efficiency street lamp heat-radiating structure which comprises a lamp body, wherein a main support is arranged in the lamp body, an LED (light-emitting diode) light source module is arranged at the lower part of the lamp body, heat-radiating cavities communicated with the main support are arranged at two sides of the main support respectively, a downward side heat-radiating support is arranged in each heat-radiating cavity, an upward baffle heat-radiating support is arranged below each side heat-radiating support, a side ventilating plate is arranged below eachbaffle heat-radiating support, the lower parts of the main support and the side ventilating plates are respectively provided with lower venting holes, each side heat-radiating support of the high-efficiency street lamp heat-radiating structure is of a downward structure, the side heat-radiating supports and the baffle heat-radiating supports are arranged inside the lamp body, and the lower parts of the main support and the side ventilating plates are respectively provided with the lower ventilating holes, therefore, water accumulation and dust coverage are avoided, and a long-term heat-radiating effect is ensured; in addition, aluminum profile materials can be combined into the lateral heat-radiating supports and the baffle heat-radiating supports, and therefore, the weight of the street lamp is lightened by half compared with the traditional street lamp in the premise of ensuring enough heat-radiating area, not only the materials are saved, but also a long-term heat-radiating effect is ensured.

Description

technical field [0001] The invention relates to a high-efficiency street lamp heat dissipation structure. Background technique [0002] The radiator fins of traditional LED street lamps are usually upwardly structured and exposed outside the housing, which is easy to accumulate water and be covered by dust, which affects the heat dissipation effect. On the other hand, most of the traditional LED street lamp shells are die-cast aluminum shells. The LED light source is installed inside the large-volume cavity, sealed with lamps, and the radiator is mounted on the shell. This structure is heavy and the heat dissipation area cannot Guaranteed, it is easy to cause poor heat dissipation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-efficiency street lamp heat dissipation structure with good heat dissipation performance to prolong the service life of the street lamp. [0004] In order to solve the above-ment...
