Abstract

A high-beam and low-beam integrated headlamp comprises a lamp body, an LED substrate, a first LED chip, a first reflecting cover, a second LED chip, a second reflecting cover and a lens. A multifunctional light barrier is arranged in front of the LED substrate, the top face of the multifunctional light barrier is provided with a low-beam forming face used for forming a low-beam light pattern, and emergent light of the first LED chip is sequentially reflected by the first reflecting cover, blocked by the low-beam forming face and refracted by the lens to form the low-beam light pattern. The bottom face of the multifunctional light barrier is provided with a curved or inclined reflecting face, emergent light of the second LED chip is sequentially reflected by the second reflecting cover, reflected by the reflecting face and refracted by the lens to form a central light spot, and the low beam light type and the central light spot are combined to form a high beam light type. The original light barrier is utilized, and the reflecting surface is formed at the bottom of the light barrier, so that light rays of the second LED light source can strengthen the light gathering effect after passing through the reflecting surface, and the problem that the central light intensity of the low beam light pattern is insufficient is solved.

Description

Technical field [0001] The present invention relates to headlights, especially a forward light having a distant near-optical. Background technique [0002] At present, the front light of the vehicle must have both high-light irradiation function and a near-light irradiation function. There is also a remote light in the LED forward lamp, such as a general-purpose LED headlight of CN105135317B, including a light shining mechanism The light blocking mechanism includes a first light block for forming a left driving, for forming a second light blocking of the right driving, driving the light shield and forms a high-light optical type. The drive mechanism and a switching mechanism for switching the use of two receiving sheets, the first shield, a finite aperture, and a second shroud is provided with a limited bit plate, a restricted plate. The top surface of the limit hole, the top surface of the limit plate is a slope; the switching mechanism includes a limit hole on the first shield,...
