Irradiation angle-adjustable plug-in LED street lamp

Abstract

The invention relates to an LED street lamp, in particular to a plug-in LED street lamp with an adjustable irradiation angle, comprising a slot-shaped casing, an aluminum substrate located in the casing, LED lamp beads mounted on the top panel of the aluminum substrate, and The insulating layer on the top panel of the aluminum substrate is fixed with a transparent glass plate on the top of the casing; wherein: two groove-shaped hanging fasteners are arranged on the outer walls of the two long side walls of the casing. The two side walls are not of equal height, and the high side wall of the hanging fastener extends to the outer wall surface of the long side wall of the casing and is fixed with the outer wall surface as a whole; The low side walls of the two hanging fasteners are in adjacent positions, and there is a sliding space between the low side walls of the two hanging fasteners; an installation connecting frame is arranged above the outer wall of the floor of the housing. The advantages of the present invention due to the structure are: convenient installation, not restricted by narrow space, reduced labor intensity, reduced maintenance cost in the later period, and improved use adaptability.

Description

technical field [0001] The invention relates to an LED street lamp, especially a plug-in LED street lamp with adjustable irradiation angle, which is easy to install, not limited by a narrow space, reduces labor intensity, reduces maintenance costs in the later stage, and improves use adaptability. Background technique [0002] In some public corridors such as expressway tunnels, residential areas or shopping mall corridors, LED street lights used in mining underground passages generally include a slot-shaped housing, an aluminum substrate located in the housing, and LEDs installed on the top panel of the aluminum substrate. The lamp beads and the insulating layer coated on the top panel of the aluminum substrate, one end of the cable fixed on the bottom panel of the aluminum substrate through a cable joint, the other end of the cable passes out of the housing, and a transparent glass plate is fixed on the top of the housing , the outer walls of the two short side walls of th...

AI Technical Summary

Problems solved by technology

When installing LED street lights of this type of structure, they are directly fixed on the wall through expansion bolts. Since some installation points are in some places where the operating space is relatively small, this brings great inconvenience to the installation. LED street lights at these installation points It is extremely inconvenient to replace once the service life is reached

Specifically, when the operating space is narrow and the size of the LED street lamp remains unchanged, it is necessary to find ways to remove the LED street lamp first. In this process, it is quite time-consuming and labor-intensive, which brings great difficulty to the workers.

Moreover, once it is fixed and installed, the irradiation area is fixed and cannot be adjusted, even if the adaptability is poor during use

[0003] To sum up, the installation of LED street lamps in the prior art is limited by the narrow installation space, high follow-up maintenance costs, high labor intensity of workers and poor adaptability during use.
