LED street lamp capable of adjusting light-emitting area

Abstract

The invention relates to the technical field of LED street lamps. The utility model relates to an LED street lamp capable of adjusting a light-emitting area. The LED street lamp comprises a lamp pole,lamp arms are fixedly connected to the two sides of the lamp pole, one side, away from the lamp pole, of the bottom of the lamp arm is fixedly connected with a light-emitting area regulating device,a tripod is fixedly connected to the top of the left side of the lamp pole, a cleaning device is fixedly connected to the top of the tripod, a supporting rod is movably connected to the top of the right side of the lamp pole, an angle adjusting device is movably connected to the right side of the lamp pole and located below the supporting rod, and solar panels are movably connected to the sides, away from the lamp pole, of the supporting rod and the angle adjusting device. According to the invention, a convex lens can be driven to move up and down, when the convex lens is close to the LED lamp, light rays emitted by the LED lamp can be condensed, the penetrating power of the LED lamp is higher, illumination is provided for people when the visibility is low in foggy days, and when the convex lens is far away from the LED lamp, the light rays emitted by the LED lamp can be diffused, so that the light emitting area is increased to meet different requirements.

Description

technical field [0001] The invention relates to the technical field of LED street lamps, in particular to an LED street lamp with an adjustable luminous area. Background technique [0002] Street lamps are lamps that provide lighting functions for roads, and generally refer to lamps within the range of road lighting in traffic lighting. Street lights play an irreplaceable role on the way people travel. They can point out the way forward and bring people a sense of security. At the same time, neat street lights are a beautiful landscape. [0003] Most of the street lamps now have a fixed light-emitting area unless the entire street lamp is replaced. However, in foggy weather, visibility is low, and LED street lamps cannot provide better lighting. It will reduce the efficiency of absorbing solar energy. Therefore, we propose an LED street lamp with adjustable luminous area. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencie...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an LED street lamp with an adjustable luminous area, which has the advantage of adjusting the luminous area, and solves the problem of low visibility in foggy weather. The luminous area of ​​the LED street lamp is fixed and cannot be adjusted. Provide better lighting, but also reduce the efficiency of absorbing solar energy if there is too much dust on the solar panel
