Abstract:
An automobile lamp comprising a light source, a shade covering the light source, a reflector with an aperture, an outer lens covering the aperture, and an inner lens arranged vertically between the shade and the outer lens wherein:the reflector comprises a central reflecting surface directing light emitted from the light source to the inner lens, a left reflecting surface, and a right reflecting surface;the inner lens substantially covers the central reflecting surface of the reflector;light distribution patterns are formed by light reflecting from the left and right reflecting surfaces and light passed through the inner lens;the inner lens is substantially V-shaped having a vertex in an illuminating direction, and has at least one prismatic cut arranged on an inner surface symmetrically relative to a horizontal line passing through the vertex and center of the light source, such that a series of prismatic cuts are shaped as a series of right circular cylinders, and at least one light-transmitting cut arranged on an outer surface symmetrically in steps relative to a horizontal line passing through the vertex and center of the light source.
