Street lamp device capable of automatically adjusting brightness

Abstract

A street lamp device capable of automatically adjusting brightness comprises a box body, a cavity with an opening in the lower side is formed in the box body, rotating blocks which are symmetrical left and right are fixed to the front inner wall and the rear inner wall of the cavity, fixing columns are fixed to the upper sides of the rotating blocks, and two sliding grooves which are symmetrical left and right are formed in each fixing column. According to the intelligent street lamp device capable of changing the light brightness, the brightness of a main lamp can be automatically enhanced and the position of light can be lowered when it is sensed that a person is under the street lamp, the irradiation brightness of the light under the street lamp can be increased, the auxiliary lamp canbe turned on, a reflector can be turned on at the same time, and the light in the device is reflected downwards, the light is enhanced again, and the device is simple in structure, convenient to use and practical.

Description

technical field [0001] The invention relates to the field of street lamp devices, in particular to a street lamp device with automatic brightness adjustment. Background technique [0002] Existing street lamps are generally fixed on lampposts. For people or vehicles passing by under the street lamps, the street lamps will change the brightness of the street lamps under the action of sensors, and restore the brightness afterwards, which can save energy. However, the existing street lamps cannot adjust the brightness The method is too single, it can only be an adjustment method, and if the lamp is burned out, the brightness adjustment of the lamp cannot be realized, and the lamp is fixed on the lamp post, and the irradiation distance of the lamp cannot be changed. A street lamp device that can change the irradiation distance and adjust the brightness in multiple ways. The existing street lamp device does not have the function of changing the brightness of the street lamp in mu...

[0002] Existing street lamps are generally fixed on lampposts. For people or vehicles passing by under the street lamps, the street lamps will change the brightness of the street lamps under the action of sensors, and restore the brightness afterwards, which can save energy. However, the existing street lamps cannot adjust the brightness The method is too single, it can only be an adjustment method, and if the lamp is burned out, the brightness adjustment of the lamp cannot be realized, and the lamp is fixed on the lamp post, and the irradiation distance of the lamp cannot be changed. A street lamp device that can change the irradiation distance and adjust the brightness in various ways. The existing street lamp device does not have the function of changing the brightness of the street lamp in multiple ways. A street lamp device with automatic brightness adjustment described in the present invention can solve the above problems
