Abstract:
1. A vehicle lamp comprising: a light source which is placed to be directed toward a front of the lamp; a translucent member which is placed to receive light from the light source; and a reflector which is placed to reflect the light from the LED light source that is transmitted through the translucent member, toward the front of the lamp, wherein an internal reflection portion and a refraction portion are formed on a surface of the translucent member, the internal reflection portion internally reflecting small-angle incident light in a direction which is substantially perpendicular to an optical axis of the light source, the small-angle incident light being incident on the translucent member at a small angle with respect to the optical axis, the refraction portion refracting large-angle incident light in a direction which is substantially perpendicular to the optical axis, the large-angle incident light being incident on the translucent member at a large angle with respect to the optical axis; and wherein a reflective surface of the reflector is configured by a plurality of reflective elements which reflect the light from the light source that is transmitted through the translucent member, toward the front of the lamp, and the reflective elements are placed in a stepwise manner via stepped portions elongating in a direction which is substantially perpendicular to the optical axis.
