Abstract:
A vehicle lamp includes a lamp unit which in turn includes a first lamp unit and a second lamp unit each provided with a light transmitting member and is configured to irradiate light emitted from a light emitting element toward a front of the vehicle lamp through the light transmitting member. In each of the first and second lamp units, the light transmitting member includes a direct light controller that directly emits light incident from the light emitting element onto the light transmitting member, toward the front of the vehicle lamp, and a total reflection controller that totally reflects the light and then emits the light toward the front of the vehicle lamp. A total reflection surface of the total reflection controller is divided into a plurality of reflection regions in a circumferential direction around the direct light controller.
