led street light for road lighting

Abstract

The invention relates to an LED streetlamp for roadway illumination. The LED streetlamp comprises a lamp post. The top end of the lamp post is provided with an extension rod transversely arranged. The extension rod is provided with an LED lamp. The outer wall of the end, close to the ground, of the lamp post is provided with an LED lamp control device connected with the LED lamp. The LED lamp control device comprises a mounting shell with a sealed cavity and vertically arranged. A heat insulation board capable of partitioning the sealed cavity into an upper cavity body and a lower cavity body is arranged in the sealed cavity and horizontally arranged. An extract ventilator fixed to the heat insulation board is arranged in the upper cavity body. A tapered air duct located over the extract ventilator is further arranged in the upper cavity body. A heat dissipation ventilation pipe communicated with the tapered air duct is arranged at the top of mounting shell. The top end of the heat dissipation ventilation pipe is sealed. A plurality of annular heat dissipation ribs axially arranged along the heat dissipation ventilation pipe are arranged on the heat dissipation ventilation pipe. A streetlamp controller is arranged in the lower cavity body. The LED streetlamp has the advantages of being good in stability and heat dissipation.

Description

technical field [0001] The invention belongs to the technical field of lighting, in particular to an LED street lamp used for road lighting. Background technique [0002] Street lamps are mainly used for lighting, and the extinguishing and opening of street lamps are generally controlled by a street lamp controller. Street lights are generally installed on light poles, which are installed on both sides of the road, and street light controllers are arranged inside or on the outer wall of the light poles. When vehicles on the road pass by, if the installation of the street lamp controller is unstable, the service life of the street lamp controller will be shortened due to the vibration of the road surface (vehicle driving or other reasons), and secondly, poor heat dissipation will also lead to a shortened service life. In order to enhance the installation stability and prolong the service life of the street light controller. Therefore, there is an urgent need to develop an L...
