Abstract
A kind of car lamps and lanterns lens, it is characterized by: being equipped with interior len (2) below the main lens (3), interior len (2) bottom is equipped with groove (4), light source (1) is equipped in groove (4), the focus of the main lens (3) is focus A, the virtual focus of the interior len (2) is overlapped with the focus A of main lens (3), the upper surface of the interior len (2) is light-emitting surface (21), light-emitting surface (21) is paraboloid, paraboloidal focus is overlapped with light source (1) center, upper surface in the groove (4) of interior len (2) is incidence surface (22), incidence surface (22) is connect with a concave surface by two convex surfaces and is formed, concave surface is located among two convex surfaces, the light that light source (1) issues is pooled to concave surface by the absorption on convex surface, the reverse extending line position of light after being reflected by concave surface In focus A.The present invention can be improved the utilization efficiency of light source.
Description
Technical field
The present invention relates to automobile lamp parts technical fields, more particularly to a kind of car lamps and lanterns lens.
Background technique
With the development and the improvement of people's living standards of society, get their way into people's lives from automobile.Auto lamp is
Guarantee safe driving and is mounted on the various traffic lights on automobile.It is divided to headlamp and signal lamp two classes.Qualified auto lamp should accord with
Close corresponding luminosity, coloration and Essential Environment test specification.
LED light source is just applied rapidly in automobile lamp industry at present.On distance light implementation, LED+ is mainly used
Lens or LED+ reflecting mirror+lens mode are realized.A common deficiency of the two is that the utilization efficiency of LED light source is inadequate
It is high.The reason of essence is needed with light value (focal length for depending primarily on lens) and light source utilization efficiency (aperture of lens and coke
Away from ratio) between must not be optimal without one combination selection, under the limitation of certain size, it is impossible to both accomplish simultaneous
It cares for.
Summary of the invention
In view of the above problems, the purpose of the present invention is to provide a kind of car lamps and lanterns lens, to solve above-mentioned background skill
The problem of being proposed in art.
The technical scheme is that being accomplished by the following way: a kind of car lamps and lanterns lens, including it is light source, interior
Mirror and main lens, the main lens lower section are equipped with interior len, and interior len bottom is equipped with groove, is equipped with light source, the master in groove
The focus of lens is focus A, and the virtual focus of the interior len is overlapped with the focus A of main lens, and the upper surface of the interior len is
Light-emitting surface, light-emitting surface are paraboloid, and paraboloidal focus is overlapped with light source center, and the upper surface in the groove of interior len is into light
Face, incidence surface are connect with a concave surface by two convex surfaces and are formed, and concave surface is located among two convex surfaces, and the light that light source issues is through excess convexity
The absorption in face is pooled to concave surface, and the reverse extending line of the light after being reflected by concave surface is located at focus A.
The present invention can be improved the utilization efficiency of light source, realize that lens are smaller to the light source imaging of same size, i.e., more focus
To realize the raising for matching light value.
Detailed description of the invention
Fig. 1 is structure chart of the invention.
In figure: 1 being light source, 2 be interior len, 3 be main lens, 4 be groove.
Specific embodiment
Known by Fig. 1, a kind of car lamps and lanterns lens, including light source 1, interior len 2 and main lens 3,3 lower section of main lens
Equipped with interior len 2,2 bottom of interior len is equipped with groove 4, and light source 1 is equipped in groove 4, and the focus of the main lens 3 is focus A, institute
The virtual focus for stating interior len 2 is overlapped with the focus A of main lens 3, and the upper surface of the interior len 2 is light-emitting surface 21, light-emitting surface 21
For paraboloid, paraboloidal focus is overlapped with 1 center of light source, and the upper surface in the groove 4 of interior len 2 is incidence surface 22, enters light
Face 22 is connect with a concave surface by two convex surfaces and is formed, and concave surface is located among two convex surfaces, and the light that light source 1 issues is by convex surface
Absorption is pooled to concave surface, and the reverse extending line of the light after being reflected by concave surface is located at focus A.
