Sunlight lighting device and tunnel lighting system

Abstract

The invention discloses a sunlight lighting device and a tunnel lighting system. The sunlight lighting device comprises a reflecting mirror / heating plate, a reflecting mirror bracket, a main bracket,a spraying device, a water storage device and a base, the reflecting mirror is connected with the reflecting mirror bracket through a mirror surface rotating shaft, and the heating device is arrangedat the back of the mirror surface of the reflecting mirror; the reflector bracket is connected with the main support through a support rotating shaft, the top of the reflecting mirror bracket is provided with the spraying device, the spraying device is connected with the water storage device through a first connecting pipe, and the water storage device and the main support are both fixed on the base. Sunlight is directly adopted to illuminate a tunnel on the basis of the principle of mirror surface one-time reflection. The reflecting mirrors are rotated according to the solar altitude angle and the solar incident angle of the mirror surface rotating shaft and the support rotating shaft at different moments, so that sunlight is reflected into a tunnel, meanwhile, the reflecting mirror is cleaned through the spraying device, and the cleanliness of the surface of the surface of the reflecting mirror is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tunnel lighting, in particular to a solar lighting device and a tunnel lighting system. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Under the impetus of the national energy conservation and emission reduction policy, in order to reduce the increasing energy consumption of road tunnel lighting, direct sunlight lighting technology has been gradually introduced into tunnel lighting. At present, there are two main types of technologies for direct sunlight lighting tunnels, namely light pipe lighting technology and fiber optic lighting technology; among them, light pipe lighting technology transmits sunlight to the area to be illuminated through multiple reflections of sunlight in the light pipe. area, although this structure has the advantages of simple structure and r...

Problems solved by technology

At present, there are two main types of technologies for direct sunlight lighting tunnels, namely light pipe lighting technology and fiber optic lighting technology; among them, light pipe lighting technology transmits sunlight to the area to be illuminated through multiple reflections of sunlight in the light pipe. area, although this structure has the advantages of simple structure and relatively low economic cost, but due to the large number of reflections, the sunlight attenuates quickly in the light guide pipe, and the utilization rate of sunlight is low; according to the latest research technology, every 15 The solar light loss coefficient in the ft (4.57m) light guide is 78.5%. Due to the above reasons, this method has great limitations in tunnel lighting. Currently, it is usually used in space lighting that does not require much transmission distance, such as underground garages, etc.

[0004] Although the solar fiber optic lighting technology transmits sunlight through low-loss silica fibers, it still has the limitation of high fiber costs.

Therefore, the inventor believes that the existing technology has technical problems such as high light attenuation, low utilization rate of sunlight or high cost, which limits the practical application of using sunlight to tunnel lighting
