HEADLAMP WITH INTEGRATED HIGH AND LOW BEAM

摘要

Disclosed is a headlamp with an integrated high and low beam. The headlamp comprises a light-emitting body assembly (1), wherein the assembly has a light-emitting body and a reflection surface (14) directed at the light-emitting body, the light-emitting body being a light-emitting diode (11) and the reflection surface (14) being composed of multiple segments of curved faces with different radii connected together, each segment of curved face smoothly transitioning to the next; an optical lens (2), wherein after light beams from the light-emitting body are reflected by the reflection surface (14), the light beams are radiated from the optical lens (2), the optical lens (2) being a non-hemispherical convex lens structure with one side of the lens facing towards the light-emitting body being a planar face and the other side being multiple segments of protruding curved faces of different diameters, each curved face smoothly transitioning to the next; and an anti-glare tilting panel (3) provided between the optical lens (2) and the light-emitting body and located between the lens end face and the light-emitting diode (11), to enable all passing light beams to pass through or to block some, switching the illumination between high beam and low beam. The focal point of the optical lens (2), a horizontal light beam cut-off face at the top of the anti-glare tilting panel (3), and the top face of the light-emitting diode (11) are all on the same horizontal plane and the focal point of the optical lens (2) is located on the centre line in the thickness direction of the anti-glare tilting panel (3).
