Abstract
The utility model discloses a kind of special-shaped lens, which is characterized in that including lens body, in one square planar of the middle position of lens body；In the top of square planar, one upward parabolic surface is set；In the lower section of square planar, an arc-shaped surface is arranged in the lower section of platform to lower platform in setting one；One side plane is set before and after parabolic surface；Four rectangular chamferings are set on four angles of platform；In parabolic surface four side chamferings of setting same as side plane junction；The utility model has technical effect that, using the structure of special-shaped lens, can disperse for gathering focal energy, at the same time it can also design and produce different shapes, assembly method is drawn close to plastic lens, the size for reducing lens mitigates the weight of lens.
Description
Technical field
The utility model relates to lens more particularly to a kind of special-shaped lens.
Background technique
Headlight for vehicles lens generally use the high-boron-silicon glass material that refractive index is 1.470 at present, and refractive index is lower.Design
Lens it is thicker.Existing automobile lens are mostly based on circle, and outer dimension is bigger, and component is also than heavier.Meanwhile it is circular
The light source of mirror is easy to gather energy in focus, be easy to cause lamp outer casing to have no idea to give out excessive energy, leads to lamp
It is excessively high to have temperature, meanwhile, cause brightness inadequate instead.
Utility model content
The purpose of this utility model is according in place of above-mentioned the deficiencies in the prior art, and the utility model aim is realized a kind of different
Shape lens, which is characterized in that including lens body, in one square planar of the middle position of lens body；In the upper of square planar
One upward parabolic surface of side's setting；In the lower section of square planar, setting one is to lower platform, one circle of setting in the lower section of platform
Arc curve；One side plane is set before and after parabolic surface；Four rectangular chamferings are set on four angles of platform；It is throwing
Object line curved surface four side chamferings of setting same as side plane junction.
Further, the focal radius of the parabolic surface is 40mm-60mm；The radius of the arc-shaped surface is
80mm-100mm。
Further, the platform with a thickness of 5mm-10mm.
Further, the material of the special-shaped lens is the K51 glass that refractive index is 1.523.
The utility model has technical effect that, can be for gathering focal energy using the structure of special-shaped lens
Amount is dispersed, and at the same time it can also design and produce different shapes, assembly method is drawn close to plastic lens, reduces lens
Size, mitigate the weight of lens.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is the top view of the utility model.
Fig. 3 is the left view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that described embodiment is only the utility model a part of the embodiment, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
In conjunction with attached drawing 1, attached drawing 2, to shown in attached drawing 3, present embodiment discloses a kind of special-shaped lens, including lens body 1,
In one square planar 2 of the middle position of lens body 1；In the top of square planar 2, one upward parabolic surface 3 is set；?
An arc-shaped surface 5 is arranged to lower platform 4, in the lower section of platform 4 in the lower section setting one of square planar 2；Such structure can be with
Solve the problems, such as that light ray energy is gathered, parabolic surface 3 and arc-shaped surface 5 can be carried out for gathering focal energy
Dispersion, while the refraction of arc-shaped surface 5 can influence gathering for light, upset it and gather in focus.In addition, in parabola
A side plane 6 is arranged in the front and back of curved surface 3；The light of parabolic surface 3 can be split, in this way, further upsetting it
Gather in focus, in addition to shadow is interfered in the projection eliminated between parabolic surface 3 and arc-shaped surface 5 and other planes
It rings, four rectangular chamferings 7 is set on four angles of platform 4；In the setting four same as 6 junction of side plane of parabolic surface 3
A side chamfering 8, meanwhile, assembly method is drawn close to plastic lens, reduces the size of lens, mitigates the technology of the weight of lens
Problem is also resolved, and above-mentioned structure is mainly solved disperses for gathering focal energy, meanwhile, may be used also
To design and produce different shapes, assembly method is drawn close to plastic lens, reduces the size of lens, mitigates the weight of lens
Amount.
In order to further realize above-mentioned technical effect, the focal radius of parabolic surface 3 is 40mm-60mm；Arc-shaped
The radius of curved surface 5 is 80mm-100mm；Platform with a thickness of 5mm-10mm.The material of above-mentioned special-shaped lens is that refractive index is
1.523 K51 glass is made.
As the utility model preferred embodiment, it is obvious to a person skilled in the art that the utility model is unlimited
It, can in the details of above-mentioned exemplary embodiment, and without departing substantially from the spirit or essential attributes of the utility model
The utility model and the protection scope of the utility model are realized in other specific forms.Which point therefore, no matter come from
It sees, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the utility model is by appended claims
Rather than above description limits, it is intended that by all changes that come within the meaning and range of equivalency of the claims capsule
It includes in the utility model.Any reference signs in the claims should not be construed as limiting the involved claims.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
