Abstract:
A high-contrast miniature headlamp includes at least one light-emitting element, a first reflective surface, and a second reflective surface. The high-contrast miniature headlamp forms a virtual equivalent light source of the light-emitting element via the first reflective surface to increase the equivalent distance between the light source and the second reflective surface, thereby enhancing the contrast of the cutoff line of the beam pattern produced by the headlamp. The headlamp is so configured that, under the condition of maintaining its miniature design and reducing cost without compromising optical efficiency, a beam pattern with a high-contrast cutoff line (i.e., a high-contrast beam pattern) can be generated to significantly improve the safety provided by automobile lighting.
