Patent attributes
An automobile lamp includes a light emitting element used as an initial light source, a light guide element for calculating a divergence angle and a light emitting area of the divergence angle of the initial light source, and a lens element to enhance a light extraction efficiency of the light emitting element and produce a light source with a predetermined light pattern and a high light extraction efficiency. A projecting element is used for enhancing the contrast of the light pattern of the light source, so that the automobile lamp can project a high-contrast cutoff line. A light emitting surface of the light emitting element is designed with a predetermined shape, such that no other optical component is required for projecting a light beam with a cross-section of a predetermined shape, so as to enhance a light energy utilization efficiency of the automobile lamp effectively.
