Underground light-guiding and illuminating system

Abstract

The invention provides an underground light guide lighting system, which comprises a mounting groove, a light collecting cover, a light guide and a diffuser; the mounting groove and the light collecting cover are hemispherical, and the gap between the light collecting cover and the The light collecting cover can be rotated at a small angle in the installation groove through the bearing sliding connection; the reflective surface in the light collecting cover, the reflective mirror on the lighting surface, and the inner wall of the light pipe are coated with a reflective film to reduce the light reflection loss; Diffusers are installed in the basement. Through the above method, the light guide lighting system used in the underground of the present invention can introduce sunlight into the underground space for lighting, saving electric energy; at the same time, the plane design of the lighting surface makes the installation of the lighting device not affect the traffic on the ground and the aesthetics of urban design.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an underground light guide lighting system. Background technique [0002] Generally, various devices for ventilation of indoor spaces and lighting devices for providing predetermined brightness to each indoor space are installed in spaces such as houses, large buildings, and basements. [0003] Indoor lighting generally uses the windows of the building to introduce external sunlight into the room through the windows. For buildings that are relatively closed and cannot be directly illuminated, the indoor lighting generally uses lighting fixtures. During the use of lighting lamps, it not only wastes electric energy, but also has potential safety hazards, especially for some processing workshops, shopping malls and other environments.

AI Technical Summary

Problems solved by technology

During the use of lighting lamps, it not only wastes electric energy, but also has potential safety hazards, especially for some processing workshops, shopping malls and other environments.

[0004] The light-collecting covers of the existing daylighting devices are basically spherical or apartment-shaped to take care of dustproof and not closed. This kind of daylighting device is not applicable in some cases, such as the daylighting of underground garages or basements, and its outdoor The environment is squares, roads, etc. Such a light collecting cover will cause the ground to bulge, hinder traffic and affect the appearance
