Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of solar street lamps, in particular to a heat dissipation structure of an integrated LED solar street lamp. Background Art

[0002] The existing integrated LED solar street lights will generate a lot of heat when working, which is mainly caused by long-term high-intensity light exposure of LED lamps, and will also shorten the service life of LED lamps. Usually, a heat dissipation structure is set inside the LED solar street lights to reduce the heat generated when the LED lamps are working. A dustproof net is generally required for heat dissipation. The dustproof net is easily blocked by dust during long-term use. The blocked dustproof net makes it difficult to dissipate the heat generated when the LED lamps are working. High temperature will reduce the efficiency of the LED and shorten the life of the LED. Excessive temperature will accelerate the aging and loss of the internal components of the LED lamp. For this reason, we propose a heat dissipation structure for an integrated LED solar street light.
