Abstract
An automobile lamp having a lighting pattern with a light-and-shade contrast comprises a light guiding pipe, a projecting lens, and a lightening body. Two ends of the light guiding pipe are respectively arranged a light input surface and a light output portion. A light refracting groove is arranged at a bottom surface formed in front of the light output portion and includes a long inclined surface and a short inclined surface. The projecting lens has a light input surface and an arc light output surface. The lightening body projects an original light source opposite to the light input surface of the light guiding pipe. One part of lights of the lightening body is guided to the projecting lens for projecting a lighting pattern with a light-and-shade cut-off line, and the other part of lights is guided toward the lighting pattern to partially overlap the lighting pattern.
