Solar street lamp capable of automatically adjusting irradiation range

Abstract

The invention discloses a solar street lamp capable of automatically adjusting the irradiation range. The solar street lamp comprises a mounting pipe, wherein a supporting disc is fixedly connected to an upper end face of the mounting pipe, a connecting rod is rotationally connected into the mounting pipe and rotationally connected with the supporting disc in a penetrating mode, and a plurality of adjusting plates are axially arranged on a side wall of the supporting disc; a supporting mechanism used for supporting the adjusting plate is arranged between the adjusting plate and the supporting disc. By arranging the adjusting plates of the fan-shaped structures, the street lamp is annularly arranged, the irradiation area of a single street lamp is increased, meanwhile, the light irradiation area of the street lamp is conveniently adjusted by rotating and adjusting the adjusting plates to form a certain angle with the horizontal direction, and light intensity of the environment where the street lamp is located is collected and determined by utilizing the light sensor; the driving motor is controlled to drive the lifting screw rod to rotate and drive the lifting pipe to lift, so the included angle between the adjusting plate and the horizontal plane is automatically adjusted, namely, the irradiation area of the street lamp is increased, and the irradiation effect is improved.

Description

technical field [0001] The invention relates to the technical field of solar street lamps, in particular to a solar street lamp that automatically adjusts the irradiation range. Background technique [0002] Street lamps are an important part of public facilities. At present, the power supply of existing street lamps mainly uses municipal electricity. Although it can achieve the purpose of lighting, it needs to consume a large amount of municipal electricity, and the wiring installation workload is large, and the investment cost High, and the maintenance is cumbersome and cannot be moved. In addition, in some areas where municipal electricity cannot be covered, street lamps cannot be used for lighting due to lack of electricity, which brings a lot of inconvenience to pedestrians.

[0002] Street lamps are an important part of public facilities. At present, the power supply of existing street lamps mainly uses municipal electricity. Although it can achieve the purpose of lighting, it needs to consume a large amount of municipal electricity, and the wiring installation workload is large, and the investment cost High, and maintenance is cumbersome, can not be moved

In addition, in some areas where municipal electricity cannot be covered, street lamps cannot be used for lighting due to lack of electricity, which brings a lot of inconvenience to pedestrians.

[0003] Most of the existing solar street lights are fixed when they are in use. Due to the limited lighting range of street lights, the installation distance between street lights needs to be considered during the actual installation process to avoid large lighting blind spots of street lights in lighting. It is necessary to consider increasing the laying density of street lamps. When the laying density is high, it will lead to an increase in lighting costs.
