Light guide lighting device for underground building and use method of light guide lighting device

Abstract

The invention relates to a light guide lighting device for underground buildings and a using method thereof, and relates to the technical field of building daylighting, the light guide lighting device comprises a lighting cover, a light guide cylinder and a diffuser, the lighting cover is arranged at the top end of the light guide cylinder, the diffuser is arranged at the bottom of the light guide cylinder, a circular ring is rotatably arranged in the light guide cylinder, and the circular ring is arranged in the light guide cylinder. A plurality of light guide grids used for sealing the light guide cylinder are rotationally arranged in the circular ring, a light guide assembly is arranged on the circular ring, and the light guide assembly is used for driving the light guide grids to rotate in the circular ring; a rotating assembly is arranged on the light guide cylinder and used for driving the circular ring to rotate in the circumferential direction of the light guide cylinder. The device has the effects that the inclination angle and direction of the light guide grating are adjusted to be flush with the solar rays, the lighting efficiency is improved, and energy is reasonably utilized.

Description

technical field [0001] The invention relates to the technical field of building lighting, in particular to a light guide lighting device for underground buildings and a method for using the same. Background technique [0002] At present, underground buildings are buildings built in rock or soil layers. It is the product of the rapid development of modern cities. It plays a role in alleviating urban contradictions and improving the living environment. It is underground and the building scale is large. In order to meet the needs of operation and management contrast illumination, a large number of lighting fixtures need to be installed. [0003] In the related art, the Chinese patent with authorized announcement number CN209330440U provides a light guide lighting system for urban rail transit underground vehicle depots and parking lots, which includes lighting devices arranged on the ground, and the lighting devices include lighting covers connected in sequence , light guide t...

AI Technical Summary

Problems solved by technology

[0004] In the process of implementing this application, the inventor found that there are at least the following problems in this technology: when the underground building needs strong light, it is necessary to rotate and adjust the light guide grid, but the position of the sun will change with time, and the light guide grid The angle of inclination cannot be adjusted to the position where it is completely flush with the sun's rays, and the lighting efficiency is poor, so it needs to be improved
