Embodiment 1

[0037] Manufactures lenticular lens headlamps. Such as figure 1 As shown, in this example, a halogen lamp or a discharge lamp is used as the light source 1, and the emitted light becomes converging after passing through the reflector 2, and the shading plate 3 acts as an aperture stop, and the light enters the biconvex lens after passing through the shading plate 3 4, the focal point of the lenticular lens 4 is designed near the shading plate, and the cut-off line is located at the 25-meter test screen. It ensures a clear cut-off line and meets the requirements of low-beam technical regulations. The lenticular lens 4 is fixed on the lamp body 8 by the lens bracket 5, which ensures the stability of the optical performance of the vehicle lamp.

[0038] In the automobile headlight based on the lenticular lens of this embodiment, the inner mirror surface of the lenticular lens is a spherical surface, and the outer mirror surface of the lenticular lens is a free-form reflective ...

Embodiment 2

[0048] In this embodiment, the convex height of the inner mirror surface of the biconvex lens is 3.3mm, and the convex height of the outer mirror surface is 22.76mm. The maximum diameter of the biconvex lens is 73.7mm. The ratio of the maximum curvature radius of the inner mirror surface to the outer mirror surface of the biconvex lens is 3.46:1. The inner mirror spherical radius is 180mm. Other than that, the same as in Example 1, the lenticular lens headlamp of the present invention was obtained.

Embodiment 3

[0050] Except in this embodiment, the convex height of the inner mirror surface of the biconvex lens is 4.1 mm, and the convex height of the outer mirror surface is 24.06 mm. The maximum diameter of the biconvex lens is 80.5mm. The ratio of the maximum curvature radius of the inner mirror surface to the outer mirror surface of the biconvex lens is 4.2:1. The inner mirror spherical radius is 190mm. Other than that, the same as in Example 1, the lenticular lens headlamp of the present invention was obtained.

Abstract

The invention provides a car head light based on the biconvex lens, characterized in that the main light source is the discharge lamp or the halogen lamp, and the car head light is composed of a free-form surface reflector, a light screen, a biconvex lens, a lens holder and the like. The car head light based on the biconvex lens of the invention adopts the free-form surface reflector, to make the light source emergence flock. The focus of the biconvex lens is set near the dead line of the light screen to make the dead line distinct. The biconvex lens design can avoid the damage of the car lighting circle, the matched mirror or the other parts on the car caused by the light focus of the sunshine. The invention reduces the risk of the light design, advances the safety, the stability and the service life, has strong universality, which is suitable for a plurality of models of cars.

Description

technical field [0001] The present invention relates to an automobile headlamp, and more particularly, the present invention relates to an automobile headlamp based on a lenticular lens. The automobile headlight includes low beam, high beam, and front fog lamp, and the automobile headlight adopts a double-convex lens design, thereby effectively preventing sunlight from focusing and burning the lamp or other parts on the automobile after being reflected by the lens. , thus greatly improving the safety and service life of the lights. Background technique [0002] The development of automobile headlights has gone through more than 120 years of evolution from the first generation - acetylene gas headlights to the current free-form surface, projection lamps and LED concept headlights. Generally speaking, a car headlight is composed of three main components, namely a light source, a reflector and a light distribution mirror. For aerodynamic and styling considerations, the front ...
