High light efficiency wide-angle natural heat dissipation LED road lamp

Abstract

The invention relates to a high light efficiency wide-angle natural heat dissipation LED street lamp, which comprises a lamp post, an elbow pipe, and a lamp cap, wherein the lamp post is connected with the lamp cap; the lamp cap consists of a lampshade, a lamp shell, a lamp source mounting board, an LED light source board, and a light transmission cover; the lower end surface of the lampshade is connected with the lamp shell and the lamp source mounting board; the LED light source board is packaged on the lamp source mounting board by the light transmission cover; a pipeline of the lamp post close to the ground is provided with a plurality of vent holes; a bending part of the lamp post is welded with the elbow pipe; the lamp post and the elbow pipe are hollow pipes; both ends of the elbowpipe are air intakes, the welding position at the upper end is communicated with the lamp post; a clearance is reserved between two side plates or four side plates of the lamp source mounting board and the lamp shell; and the two side plates or the four side plates of the lamp source mounting board are provided with a plurality of through holes, and the through holes on the lamp source mounting board, a plurality of through holes on the lamp post and the elbow form a natural heat dissipation channel. The street lamp is integrated with heat dissipation, dust prevention, insect prevention, and water resistance, and is widely used for road lighting of various occasions.

Description

technical field [0001] The invention relates to an LED street lamp device, in particular to a high-efficiency wide-angle natural heat-dissipating LED street lamp integrating heat dissipation, dustproof, insect-proof and waterproof. Background technique [0002] As a new type of lighting source with environmental protection, energy saving, long service life and good luminous effect, LED is widely used in road lighting. For LED street lamps, the requirements for heat dissipation, dustproof, insect-proof, and waterproof are very high. Dust-proof, insect-proof, and waterproof generally adopt a closed structure, and the heat dissipation of LED needs to rely on the circulation of air. The considerations are not comprehensive, and the safe use and lifespan of street lamps cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a high light efficiency with go...
