HIGH/LOW BEAM HEADLIGHT STRUCTURE FOR AUTOMOBILE LAMPS AND LIGHTING DEVICE HAVING INTEGRATED HIGH/LOW BEAMS

摘要

A high/low beam headlight structure for automobile lamps, comprising: a light source end, a light path transmission end, and an emitting end, wherein the light source end and the light path transmission end form an integrated assembly by means of a heat sink; the light path transmission end is used for receiving light rays emitted by the light source end and completing, at one time, a light pattern that may comply with regulatory requirements for reception by the emitting end and forming road surface illumination; and a lighting device provided with integrated high and low beams that is set up according to the foregoing, which may eliminate a sun visor and implement the one-time formation of the light pattern required by regulations, while improving the light utilization efficiency, saving space, and reducing the cumulative error caused by the multiple assembling of parts. The low-beam light path transmission end is configured to be arranged at an interval from the high-beam light path transmission end so as to avoid light crossing between the high and low light beams; the low-beam light-emitting end and the high-beam light-emitting end are arranged in a spatially overlapping manner, such that a driver is provided with seamless vision switching and smooth transitions when switching between high and low beams; and unevenness and dark areas at the junction of high and low beams are avoided after the low beam is switched to the high beam.
