Document Type and Number:
WIPO Patent Application WO/2022/224706
Kind Code:
A1
Abstract:
Provided is a vehicular lamp comprising an inner lens suitable for light diffusion. This vehicular lamp comprises a light-emitting body for surface light emission and an inner lens disposed in front of a light-emitting surface of the light-emitting body, wherein: first steps extending in one direction are formed on the incident surface of the inner lens; and second steps extending in a direction perpendicular to the first step are formed on the emission surface of the inner lens. Steps extending in the respective directions are formed to be perpendicular to each other on the incident surface and the emission surface of the inner lens, whereby incident light can be uniformly diffused in all directions. In addition, since mold machining for injection molding is easy, reproducibility is high.
