However, since the lighting means is provided for each braille projection, power consumption is high and durability is deteriorated due to heat generation of the lighting means.
A technique has been proposed in which an indirect illumination method of refracting the light of the light source through the light guide plate is adopted so that the light emitting protrusion on the upper surface of the block body can be emitted with less power.
The following Patent Document 2 discloses an indirect lighting type light-emitting type sidewalk block using a light guide plate.
