Problems solved by technology
However, due to the poor working environment of the automatic control system and other reasons, the failure rate is high, and the system maintenance is very difficult. Therefore, most of the actual projects still use a fixed brightness lighting scheme: that is, the brightness gradient value of the tunnel transition area must be less than The brightness gradient limit under the strongest sunlight at noon in summer, this limit data is obviously for the weak light (in the three seasons other than summer, especially) winter, rainy days and night, the lighting source in the brightness transition interval is There is a waste of energy

Embodiment Construction
[0031] The present invention will be further described below in conjunction with the examples, but the protection scope of the present invention is not limited only to the examples.
[0032] combine Figure 1-Figure 3 As shown, a sunlight delivery system includes a condenser 1, a dimmer mirror 2 and a reflector 6 from top to bottom. After the light is injected into the dimming mirror 2, the parallel sunlight is enhanced to the reflector 6. The reflector 6 directs the parallel sunlight from different directions to enter the interior through the 2.7-meter-high arched cross-sectional space at the top of the tunnel, and then installs it on the top. Diffuse reflector groups of different heights are evenly reflected on the road surface to realize the enhanced lighting function, and effectively solve the "black hole" and "white hole" phenomenon caused by the bright transition area of the entrance and exit due to changes in the intensity of the sun.

The invention discloses a sunlight transmission system and application thereof. The sunlight transmission system comprises a collecting mirror, a dimming mirror and a reflection mirror from top to bottom in sequence. Sunlight is emitted to the dimming mirror after being collected by the collecting mirror, is converted into enhanced sunlight at this point, is then emitted to the reflection mirror from the dimming mirror and is emitted into a tunnel from the reflection mirror; the collecting mirror and the dimming mirror are respectively mounted on an upper side surface and a lower side surface of a tracking adjusting rack, the tracking adjusting rack is located above the reflection mirror, an included angle between the tracking adjusting rack and the horizontal plane can be adjusted in a manner that the included angle between an extending line of a base point which is a central point of the collecting mirror and extends to the periphery in any direction, and the horizontal plane. The sunlight transmission system has the advantages that the use rate of solar energy is improved by ten times compared with a common light-electricity-light illuminating manner, the adaptivity is high, and the inherent performance defect that the stability of a sunlight direct illuminating system is poor sometimes is effectively avoided.
Description
technical field [0001] The invention relates to the technical field of sunlight transmission, in particular to a sunlight transmission system and its application, which is mainly used in entrances and exits of tunnels, houses, workshops and garages. Background technique [0002] For highway tunnels, in addition to the need to install day and night lighting systems to ensure the basic lighting brightness requirements, there is another great feature, that is, car drivers specifically require the brightness gradient (brightness gradient) within a certain distance from the entrance and exit of the tunnel (referred to as the brightness transition interval). rate of change) must be limited within a certain range, otherwise there will be "black hole" and "white hole" phenomena and cause accidents, that is, the brightness (compared to the brightness of the outside environment) in this important and most dangerous section is a Compared with the relative value of the brightness of the...
