Problems solved by technology

[0002] The existing double-bead LED projection headlights on the market are installed back-to-back on the heat sink with far and low beams, which causes the high temperature of the two lamp beads to gather in a narrow local location; the existing double-bead LED projection headlights The light adopts independent reflection lamp cups for far and near beams. Due to the back-to-back layout, it is easy to cause deviations in the position of the far and near beams and it is difficult to adjust; and the dual-beam projection headlights cannot achieve the optimal light distribution of the far and near beams, and cannot be effective. Lighting with dipped headlights

Abstract

The invention discloses a dual light projection headlight. The dual light projection headlight comprises a high beam module, a lens holder, a bracket and a low beam light; the low beam light is arranged in the middle of the bracket, the high beam module is arranged at the upper portion of the lens holder, and the lens holder is arranged at the front end of the bracket; the front end of the lens holder is provided with a through lens, and the flat end of a flat convex mirror faces the rear end of the lens holder; the high beam module and the low beam light are staggered, according to the principle of transmission light of a plane mirror and flat convex mirror, the upper portion of the through lens is set to be a plane mirror, so that light is transmitted better, and the irradiation distanceof a high beam light is greatly increased; the lower portion of the through lens is set to be a flat convex mirror, so that the irradiation range of the light is effectively enlarged when the low beam light irradiates, and particle light is projected through the plane mirror, so that the effect of the low beam light is better; the characteristics of the high beam light and low beam light are effectively utilized, and different light-transmitting mirrors are set, so that illumination of the high beam light and low beam light is better utilized, and smaller power and better irradiation are achieved.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a dual-light projection headlamp. Background technique [0002] The existing double-bead LED projection headlights on the market are installed back-to-back on the heat sink with far and low beams, which causes the high temperature of the two lamp beads to gather in a narrow local location; the existing double-bead LED projection headlights The light adopts independent reflection lamp cups for far and near beams. Due to the back-to-back layout, it is easy to cause deviations in the position of the far and near beams and it is difficult to adjust; and the dual-beam projection headlights cannot achieve the optimal light distribution of the far and near beams, and cannot be effective. Use low beam lighting. Contents of the invention [0003] The present invention realizes above-mentioned purpose through following technical scheme: [0004] A dual-beam projection headlamp, comprising: a hi...
