Light guide blind spot area / lane change warning light for vehicles

摘要

[PROBLEMS] To reflect a light beam uniformly to a target area and display a warning light on the mirror surface of the rearview mirror if a vehicle is present behind the lane when changing lanes. Provide a light guide type blind spot area / lane change warning light for vehicles. A light source 3a and a light guide 2 including a light incident surface 2a, a first reflective surface 2b, a second reflective surface, and a light output surface, the light incident surface being positioned above the light source and emitted from the light source. A light beam is converted into a parallel light beam, a first reflecting surface inclined at an upper part of the light incident surface is installed, and a second reflecting surface and a light emitting surface are installed on both sides of the first reflecting surface, respectively. Total reflection stripes are respectively provided on the reflection surfaces, and the total reflection stripes on the first reflection surface totally reflect parallel rays on the second reflection surface and form uniform warning light on the light exit surface.
