Abstract

The invention discloses a lighting device capable of automatically changing brightness for an underground passage. The lighting device comprises an underground passage body. a supporting top plate isinstalled at the innermost end of the underground passage body, circular holes are evenly formed in the lower part of the supporting top plate from left to right, lighting lamp mechanisms are installed in the circular holes, and a power supply system is installed at one end of the top of the underground passage body, an illumination device is installed outside the underground passage body, a control mechanism is installed on the middle part of the top end in the underground passage body, and a resistor replacement mechanism is installed near the lighting lamp mechanism. The lighting device hasthe advantages of convenient operation and high practicability.

Description

technical field [0001] The invention relates to the technical field of tunnel lighting devices, in particular to a lighting device for underground passages that can automatically change brightness. Background technique [0002] The characteristics of lighting fixtures or lighting fixtures: lighting can be performed by energizing light and heat, but the lights in the existing underground passages are powered on all day long, which not only wastes a lot of electricity but also reduces the life of the bulbs. [0003] Among the traditional lighting devices, for example, CN208475065U patent is a kind of lighting device for underground passages, which realizes the effective fixing of light bulbs, solves the problem that the installation of lighting devices is too cumbersome, which leads to the increase of time for the staff to install, and improves the efficiency of lighting. installation efficiency of the device. [0004] However, automatic brightness change cannot be realized i...
