Street lamp holder

Abstract

The invention discloses a street lamp holder. The street lamp holder is installed on a lamp post, and the street lamp holder comprises a base capable of being connected and fixed to the lamp post, a supporting rod which is arranged on the base, a top cover radiator which is mounted at the top of the supporting rod, a light-transmitting cover which is arranged outside the supporting rod in a sleeving manner and is spliced between the base and the top cover radiator, a plurality of heat conduction metal pipes installed at the top in the top cover radiator, an LED light source structure arrangedon the front end faces of the heat conduction metal pipes, a light guide cup arranged on the LED light source structure in a covering mode and playing a role in guiding light, a radiator, and a drivecontrol device arranged on a base and electrically connected with the LED light source structure. The heat conduction metal pipes are arranged on the front end surface of the radiator; a support is arranged at the joint of the radiator and the heat conduction metal pipes, the LED light source structure is installed on the heat conduction metal pipes through the support, the light guide cup is installed on the support, and the front end face of the radiator faces obliquely downwards, so that the LED light source structure irradiates obliquely downwards, namely the LED light source structure irradiates a driving road surface or a pedestrian road surface.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a street lamp head. Background technique [0002] The most common existing street light structure is to include a light pole and a street light head installed on the top of the light pole, and the spherical street light head is a relatively common shape, but the existing street light heads, especially the spherical street light head, are all mounted on the top There is a light source that illuminates directly below, and the light has no inclination angle, and the light is evenly distributed outwards with the light pole as the center. The illuminance of the inner light is weak and uneven, and the street lamps are all installed on the side of the road. The above-mentioned light distribution method is centered on the light pole and diverges outward. In this way, most of the light is not irradiated on the road surface of driving or pedestrians. The light resource has not achieved the ...

Problems solved by technology

The heat generated by the LED light source is large, and the heat is concentrated in the LED chip with a small size, which will make the internal temperature of the LED chip higher and higher, which will not only accelerate the aging of the lamp, shorten the service life, and even cause the chip to burn out in severe cases.
