Patent ID: 8083388

Claim:
An automobile lamp, comprising: a light source module including: a light emitting element, having a light emitting surface in a square shape, for projecting a light beam with a cross-section in a square shape, and using the light beam as an initial light source; a light guide element, having a light incident surface and a light emitting surface, and the light incident surface being coupled to a light emitting surface of the light emitting element for receiving the initial light source, and then converging a divergence angle of the initial light source to generate a light source with a predetermined light pattern according to a divergence angle and a light emitting area of the divergence angle of the initial light source, wherein the light guide element is a rectangular light pipe which converges the divergence angle of the initial light source in a total reflection along a long side direction of the light pipe, and transmits the initial light source beams along one lateral direction of the light pipe, such that a light emitting surface of the initial light source passing through a two-dimensional plane of the light pipe in the lateral direction is maintained in a square shape; and a lens element disposed between the light guide element and the projecting element, having a light incident surface and a light emitting surface, and the light incident surface of the lens element being coupled to a light emitting surface of the light guide element, and the light emitting surface of the lens element being coupled to a light incident surface of a projecting element; and the projecting element, having a light incident surface and a light emitting surface coupled to a light emitting surface of the light guide element, for receiving the light source, such that after the contrast of the light pattern is enhanced, a high-contrast cutoff line is projected out from the light emitting surface, wherein the projecting element is an aspherical lens with at least one specific angle cut at a surface of the aspherical lens and determined by the distance of a lens axis of the aspherical lens.
