Japanese Patent JP7198409
Kind Code:
B2
Abstract:
To provide a vehicular lighting system that can achieve light emission with even brightness in a longitudinal direction while improving productivity of a light guide body.SOLUTION: A vehicular lighting system 21 comprises a light source 24 and a lengthy light guide body 25 that extends linearly in an entering direction of light from one end arranged adjacent to the light source 24 for irradiation with light from a light emission surface 32 in a linear shape. In the light guide body 25 is formed a convex part 34 arranged in a longitudinal direction on a rear face of the light emission surface 32 and extended in a direction orthogonal to an entering direction of light. Widths W1-W12 of the convex part 34 vary depending on distances from the light source 24.SELECTED DRAWING: Figure 4
