Abstract
The utility model is related to a kind of a kind of light guide at the automobile-used expansion light guide lighting visual angle for expanding optronics visual angle technology.Technical scheme is：Increase groove in light guide surface, the groove is the column structure that diameter is 0.2mm, and every groove is corresponded with each light guide tooth, and is set along at the tooth top extension line of the light guide tooth.The technical program greatly improves the lighting visual effect of light guide, expands lighting visual perspective.
Description
Technical field：
The utility model is related to optical system, more particularly to a kind of automobile-used technology for expanding optronics visual angle.
Background technology：
Novel, unique illuminating shape is pursued, is the important trend of car light development.Under the requirement of various shapes, light
Waveguide technology arises at the historic moment.The diameter of light guide is generally between 6mm-8mm, it is meant that light fixture is greatly reduced in longitudinal space, makes car
The utilization rate in body space is further improved.Light guide of the prior art is general to spread 10 degree or so in order to meet laws and regulations requirement, i.e.,
Lighting visual perspective is between 10-13 degree.Current light guide lighting visual angle is narrow.
Utility model content
The utility model provides a kind of light guide for expanding light guide lighting visual angle, the lighting vision effect that it greatly improves light guide
Really, lighting visual perspective is expanded.
Expand light guide lighting visual angle purpose to reach, the technical solution of the utility model is：Increase in light guide surface and carve
Line, groove is the column structure that diameter is 0.2mm, and every groove is corresponded with each light guide tooth, and along the light guide tooth
Tooth top extension line at set, i.e. groove is close to the side of light guide tooth, the tooth top of groove and light guide tooth on same straight line,
The spacing of groove is identical with the tooth pitch of light guide tooth.In the utility model, the length of groove, can be visual according to lighting without particular/special requirement
The size of angle determines its length, and the length of groove is directly proportional to the size of lighting visible angle.
Know-why of the present utility model is：In light guide internal communication, light runs into light guide tooth and is totally reflected light, light
Line projects photoconductive tube.Light guide groove is corresponded with each light guide tooth, and length is continuous, and light runs into groove and is also all-trans
Penetrate, lighting visual effect is observed in front side, i.e., both can see the light that light guide tooth is reflected away, it is also possible to it was observed that groove
The light for reflecting away, reaches the purpose at increase visual angle.
Compared with the scheme of existing light guide, the advantage of this patent is：
1. coordinate the effect of groove, expand the scope of light guide angle of visibility.Both ensure to increase visual angle, because groove is trickle,
Groove influences very little to light propagation efficiency.
2. groove is different from light guide tooth, and groove can not influence first wife's light and increase lighting to regard to the loss very little of light
Angle, improves the lighting visual effect of whole lamp.
Brief description of the drawings
Application examples of the present utility model is explained below in conjunction with the accompanying drawings.
Fig. 1 is the floor map that light guide increases groove.
Fig. 2 is that groove arranges detailed perspective.
Fig. 3 light guides increase the profile after groove.
Specific embodiment
As depicted in figs. 1 and 2：Increase groove in light guide surface, groove 2 is the column structure that diameter is 0.2mm, every quarter
Line 2 is corresponded with each light guide tooth 1, and is set along at the extension line of the tooth top 3 of the light guide tooth.Groove 2 is close to light guide
The side of tooth is set, and the arrangement spacing of groove 2 is identical with the spacing of light guide tooth 1, i.e., an one tooth piece groove of correspondence.
Fig. 3 is the profile after light guide increases groove.Groove 2 is set close to light guide surface,
Fig. 1 to Fig. 3 illustrates the overall structure of the design, and groove 2 is close to light guide tooth 1, visually continuous with light guide,
The length of groove can be controlled freely.Light is propagated in light guide, has diffusion effect, and then improve angle of visibility in appearance in lighting
Degree.
A kind of scheme that the utility model is implemented to provide is discussed in detail above, for those of ordinary skill in the art,
According to the thought of the present embodiment, will change in specific embodiments and applications.In sum, this specification
Content should not be construed as to limitation of the present utility model, and all any changes made according to the utility model design philosophy are all in this reality
Within new protection domain.
