ABSTRACT:
A vehicle lamp can create a desired distribution pattern easily with a simple configuration while having a thin body and light weight. The vehicle lamp can include a light source unit and a convex projection lens configured to project light from the light source unit forward in the direction of light illumination. The light source unit can include a light guide plate having a light emission surface and made of a transparent material to the visible light range and can include a light source disposed in front of one end face of the light guide plate. The projection lens can have a focus arranged on or near the light emission surface of the light guide plate. The light source unit can include a reflection sheet configured to reflect light from the light guide plate back into the light guide plate and can have a shape configured to provide a cutoff pattern. The reflection sheet can be located adjacent an edge of the light guide plate adjacent the light source. A high beam light source unit can be disposed adjacent or on the reflection sheet closer to the projection lens.
