Title:
ROAD SURFACE LIGHT REFLECTION DEVICE
Document Type and Number:
Japanese Patent JP2018180504
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a light reflection device having high intensity, excellent in wear resistance and weather resistance, and having high light reflection luminance.SOLUTION: A road surface light reflection device comprises a light transmission body 1 and a reflection layer 13. The light transmission body 1 is formed of a reinforced transparent material, and is formed of a proximal part 10 and a salient part 11. The salient part 11 and the proximal part 10 are integrally molded, and the salient part 11 is formed on an upper surface of the proximal part 10. An apex of the proximal part 10 surrounds an area which is larger than an area surrounded by bottom sides of the salient part 11. A shape of the salient part 11 is formed into an elliptical arc surface in an incident direction of a light ray from a light source. The reflection layer 13 is installed on the exterior side of the proximal part 10 of the light transmission body 1, and the light ray emitted from the light source A is transmitted in the salient part 11 of the light transmission body 1 and then enters the light transmission body 1, then is reflected through the reflection layer 13, then is emitted to a direction of the light source from the light transmission body 1 again.SELECTED DRAWING: Figure 1
