Abstract
The invention discloses a kind of compound lens of car light, include the first lens and the second lens, the front surface of first lens is consistent with the back surface shape of the second lens, and it links together, the rear surface of first lens is used with the front surface of the second lens and is processed using optical design, and the junction of first lens and the second lens forms a face of weld；By using the lens that different materials welding collocation forms, optical characteristics can change therewith, can preferably improve optical property, optimize light, improve illumination efficiency.
Description
Technical field
The present invention relates to automobile lamp technical field more particularly to a kind of compound lens of car light.
Background technology
Previously the light source used is halogen bulb and Xe lamp bulb, since fever is very big, so the lens used just select
For glass, although heat-resisting, weight is also big, and shape is also relatively simple, with the use of the development LED cold light sources of technology, makes
PC lens are obtained to be readily applicable in car light, but different materials, similar structure so that we lack for the use of lens
Therefore more development and variation, solve the problems, such as that this one kind is particularly important.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of compound lens of car light, melted by using different materials
The lens that collocation forms are connect, optical characteristics can change therewith, can preferably improve optical property, optimize light, improve illumination effect
Rate.
To solve the above-mentioned problems, the present invention provides a kind of compound lens of car light, the first lens and second are included
Lens, the front surface of first lens is consistent with the back surface shape of the second lens, and links together, first lens
Rear surface and the front surfaces of the second lens use and be processed using optical design, first lens and the second lens
Junction forms a face of weld.
Further improvement lies in that：First lens and the second lens are seamless compound come disposal molding by double-shot moulding
Together.
Further improvement lies in that：First lens are made of makrolon or polymethylacrylic acid material.
Further improvement lies in that：Second lens are made of polymethylacrylic acid or makrolon material.
Further improvement lies in that：The making material of first lens and the second lens differs.
The beneficial effects of the invention are as follows：The lens that the present invention is formed by using different materials welding collocation, optical characteristics
It can change therewith, can preferably improve optical property, optimize light, improve illumination efficiency, while pass through the change of welding face curvature
Change and realize that light is reflected to some direction, so as to obtain wider array of optical range.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is the lens of the present invention and the light path contrast schematic diagram of ordinary lens.
Wherein：The first lens of 1-, the second lens of 2-, 3- face of weld.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention is further described below in conjunction with embodiment, the present embodiment
It is only used for explaining the present invention, be not intended to limit the scope of the present invention..
As shown in Figure 1, 2, a kind of compound lens of car light is present embodiments provided, it is saturating to include the first lens 1 and second
Mirror 2, the front surface of first lens 1 is consistent with the back surface shape of the second lens 2, and links together, and described first thoroughly
The rear surface of mirror and the front surface of the second lens are used and are processed using optical design, first lens and the second lens
Junction form a face of weld 3.First lens, 1 and second lens 2 are seamless come disposal molding by double-shot moulding
It is combined with each other.First lens 1 are made of makrolon material.Second lens 2 are by polymethylacrylic acid material system
Into.The making material of first lens and the second lens differs.
The lens that the present invention is formed by using different materials welding collocation, optical characteristics can change therewith, can be preferably
Optical property is improved, optimizes light, illumination efficiency is improved, while realizes light to some direction by the variation of welding face curvature
Refraction, so as to obtain wider array of optical range.
Fig. 2 is the lens of the present invention and the comparison diagram of ordinary lens, and dotted line is the light path of the present invention, and solid line is existing lens
Light path, focus 5 be ordinary lens focus, focus 4 for the present invention in lens focus.
