Lighting device

Abstract

The invention is applicable to the field of lighting devices and discloses a lighting device which comprises a lamp casing assembly and a lighting construction member. The lamp casing assembly comprises a casing and a transparent piece, a cavity is fixedly connected with and formed between the casing and the transparent piece detachably, the quantity of the lighting construction member is at least two, and at least one illumination sensor is further arranged in the lamp casing assembly. A light reflection construction member is fixedly arranged in the lamp casing assembly, the illumination sensor is arranged in the center of the light reflection construction member, and the lighting construction member is arranged at the position of the light reflection construction member and located around the illumination sensor. The illumination sensor is arranged in the center of the light reflection construction member, light work and rest of the environment is converted into electrical signals through the illumination sensor to control opening quantity of the lighting construction member, luminance of the lighting device can be automatically regulated according to ambient light, energy consumption waste is avoided while guaranteeing lighting effects, and degree of automation is high.

Description

technical field [0001] The invention belongs to the field of illuminating devices, in particular to an illuminating device capable of automatically adjusting brightness. Background technique [0002] The current lighting device cannot adjust the lighting according to the different shades of the environment. When the ambient light is strong, the lighting brightness of the lighting device cannot be automatically reduced accordingly, resulting in waste of energy consumption. When the ambient light is weak and low, it cannot be adjusted The lighting brightness of the lighting device is automatically adjusted accordingly, and the lighting effect cannot be guaranteed. It is necessary to manually adjust the brightness of the lighting device, and the degree of automation is low. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a lighting device, which can automatically adjust the br...
