Problems solved by technology

However, this kind of lighting technology still cannot avoid that when the vehicle enters the entrance of the tunnel during the day, the brightness of the lighting in the tunnel is quite different from that of the sunlight, and the lack of brightness will cause discomfort to the driver's eyes, poor visibility, and accidents.

Embodiment 1

[0011] Such as figure 1 As shown, a kind of energy-free highway tunnel entrance reflector of the present invention includes a bracket 1 and a concave mirror 2, the concave mirror 2 is installed on the bracket 1, and there are many small round convexities 3 on the concave mirror 2.

[0012] The concave mirror of the present invention adopts titanium alloy material.

[0013] The present invention is based on installing brackets on both sides of the road at an appropriate distance from the entrance of the cave. A concave mirror is installed on the bracket. Multiple small convexities on the concave mirror reflect the light source into the tunnel to achieve the purpose of lighting.

Abstract

The invention relates to a non-energy-consumption road tunnel entrance reflective mirror and belongs to the technical field of road traffic. According to the non-energy-consumption road tunnel entrance reflective mirror, sunlight reflection is utilized to enable light to enter a tunnel entrance, and tunnel entrance illumination can be enhanced. The non-energy-consumption road tunnel entrance reflective mirror comprises a support and a concave mirror, and the concave mirror is mounted on the support and provided with a plurality of small round protrusions. Through the multi-face reflective mirror with large concave and small protrusions, sunlight is reflected to enter the tunnel entrance for enhancing illumination in advance, the defect that an existing lamp on the road tunnel entrance is insufficient in illumination technical brightness is overcome, energy is not consumed, the tunnel entrance can be effectively illuminated, and accident occurring frequency is lowered.

Description

technical field [0001] The invention belongs to the technical field of road traffic, and in particular relates to a reflector at a road tunnel entrance without energy consumption. Background technique [0002] The known tunnel lighting technology is to use electric lamps in the tunnel to illuminate the top or side of the tunnel. However, this kind of lighting technology still cannot avoid that when the vehicle enters the tunnel entrance during the day, the brightness of the lighting in the tunnel is quite different from that of the sunlight. The lack of brightness will cause the driver's eyes to experience light discomfort and poor visibility, which will easily lead to accidents. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a non-energy-consuming highway tunnel entrance reflector that can utilize sunlight reflection to allow light to enter the tunnel entrance and enhance the illuminatio...
