led street light lamp holder

Abstract

The invention relates to a street lamp for road lighting, specifically an LED street lamp lamp head; it includes a lampshade, an LED lamp bead set, and a heat sink. The back of the heat sink is provided with fins, and the bottom of the heat sink is provided with an accommodating and fitting device. The groove of the LED lamp bead set, the lampshade is sealingly connected to the edge of the groove; an air inlet is provided at the center of the fin, and the lower part of the side wall of the air inlet is composed of upper and lower sections that are rotationally connected; The lampshade is a flat lampshade, and a bendable brush is provided on its surface. One end of the brush is hinged on the edge of the groove of the heat sink, and a torsion spring is installed on the rotating shaft. There is an opening under the brush. The strip groove on the heat sink is equipped with a telescopic tube filled with alcohol inside. One end of the telescopic tube is fixed on the bar groove, and the other end drives the brush to rotate. The LED street lamp head using this technical solution can Automatically cleans dust and reduces its own weight.

Description

technical field [0001] The invention relates to a street lamp for road lighting, in particular to a lamp holder of an LED street lamp. Background technique [0002] Road lighting is an important part of urban lighting. It is closely related to people's production and life. With the acceleration of urbanization in our country, LED street lights have directional light, low power consumption, good driving characteristics, fast response, high earthquake resistance, The advantages of long service life and green environmental protection have gradually come into people's field of vision, and have gradually become the best choice for urban lighting energy-saving renovation. [0003] The lampshade of LED street lamps is generally set under the lamps. Due to long-term outdoor use, the lampshade often accumulates dust. Usually, the light transmittance of street lamps that have been used for more than one year can drop by as much as 60%. If they are not cleaned for a long time, some dus...

Problems solved by technology

[0003] The lampshade of LED street lamps is generally set under the lamps. Due to long-term outdoor use, the lampshade often accumulates dust. Usually, the light transmittance of street lamps that have been used for more than one year can drop by as much as 60%. If they are not cleaned for a long time, some dust and insects Corpses can even corrode lamp materials; existing street lamp cleaning methods are mostly manual, such as using elevators with manual scrubbing, which is inefficient and expensive; there are also manual high-pressure water washing, which is easy to damage the lampshade. Therefore, there is an urgent need for a suitable cleaning method to ensure the long-term stable operation of solar LED street lights

[0004] In addition, because LED is a semiconductor component, its chip will continue to shorten its service life due to the influence of temperature, so LED street lamps have high requirements for heat dissipation. Manufacturers need to install a large aluminum plate heat sink on the back of the LED lamp bead, which is not only costly, but also Moreover, the weight of the LED lamp head is as high as 20Kg, and the requirements for the installation column of the LED street lamp are also higher.
