Embodiment Construction
[0019] Such as Figure 2 to Figure 4 The shown light guiding system 200 suitable for tunnels includes: several light reflecting devices 201, several light guiding devices 300, several wall surface reflecting devices 400, several light sensors 500 and a main controller (not shown).
[0020] Reflective device 201 comprises a reflector 202, reflective drive motor 203 and reflective support 204; Fixedly mounted to the tunnel, the reflector 202 is rotatably connected to the reflector bracket 204 . It should be noted that the reflective driving motor 203 can directly drive the reflective plate 202 or indirectly drive the reflective plate 202 by other means such as chains or belts. The reflective device 201 is arranged at the entrance or exit of the tunnel or other positions where sunlight can enter the reflective plate 202 , such as an air vent in the middle of the tunnel.
[0021] The light guiding device 300 is used to guide the light reflected by the light reflecting device 201...

The invention discloses a light guiding system applicable to a tunnel. The light guiding system comprises a plurality of light reflecting devices, a plurality of light guiding devices, a plurality of wall surface reflecting devices, a plurality of photo sensors and a master controller. The light guiding devices are used for guiding light rays reflected by the light reflecting devices to the ground of the tunnel. Each wall surface reflecting device comprises a reflecting plate and a regulating device capable of regulating the angle of the reflecting plate. The photo sensors are fixed to the top of the tunnel and used for detecting the light intensity of the positions where the photo sensors are located. The master controller is electrically connected to the light guiding devices, the regulating devices and the photo sensors and controls the light guiding devices and the wall surface reflecting devices according to signals of the photo sensors. The light guiding system applicable to the tunnel has the beneficial effect that light conditions in the tunnel can be automatically regulated.
Description
technical field [0001] The invention relates to a light guide system, in particular to a light guide system suitable for tunnels. Background technique [0002] For road tunnels, if a car driver enters and exits the tunnel, the phenomenon of "black hole" and "white hole" may occur and cause a traffic accident. For example, once a car driver enters a tunnel with weak light (200Lx) at a high speed from a road with strong sunlight at noon (such as 60000Lx), the driver will often feel dizzy due to the large gradient of brightness change. Accidents may even occur due to loss of vision in a short period of time. Such as figure 1 As shown, in order to solve such problems in the tunnel light guide system in the prior art, the tunnel 100 is often equipped with a light guide device 101 and an optical device 102 to guide the light into the tunnel 100 so that the inside of the tunnel 100 can be illuminated, but the existing State-of-the-art light guides 102 often cannot adjust to chan...
