Specific embodiment
Below in conjunction with attached drawing and embodiment, the utility model is described further:
Embodiment 1
With reference to Fig. 1, a kind of lens unit 1 of automobile lamp, side of the lens unit 1 far from lamp source is shiny surface, is leaned on
The side of close to sources is provided with optical texture 11；
The optical texture 11 is rendered as the annulus of multiple nested settings in the section being parallel on 2 direction of lamp source.In reality
In the application of border, due to needing multiple lens units carrying out split, the lens unit in mosaic in this way can not just be formed completely
Annulus but partial arc section；Belong to the simple replacement of the present embodiment, herein only with complete annulus for example, still
Protection scope of this utility model cannot be limited by this, illustrates hereby.
Each annulus is relative to other annulus on the outside of it all in eccentric position；The optical texture is perpendicular to lamp
Section on the direction of source is rendered as sawtooth pattern, and the wave crest and trough of each sawtooth respectively correspond the annulus；Positioned at most
The annulus of inside is located at the center point of the lens unit, and is located at the surface of lamp source 2.
It is formed multiple circular ring structures of nested setting by above-mentioned setting, and is being located at 1 center of circle of lens unit
The annulus spacing in left side is less than the annulus spacing on the right side of 1 center of circle of lens unit, and the circle on the upside of the lens unit center of circle
Interannular is away from identical as the annulus spacing being located under the lens unit center of circle.
Also, the optical texture 11 divides to be gradually decreased for the identical first part 111 of height of projection and height of projection
Second part 112；The second part 112 is located at the inside of optical texture 11, and height of projection gradually drops from inside to outside
Low, the first part 111 is located at the outside of second part 112.
According to the optical texture 11 that above structure is arranged, it is as shown in Figures 2 and 3 to go out light index path, it can be clearly seen that,
On the direction A-A, light shows as the refracted light of wide-angle out, and on the direction B-B, light shows as the refraction light of low-angle out
The light shape that goes out of line, optical texture 11 entire so is just thin-and-long, light distribution no dark space, so as to meet a variety of car lights
The requirement of regulation.
In the present embodiment, the distance between center of circle of two neighboring annulus is identical, may be set to be in actual design
It is not identical.Likewise, the center of circle of the multiple annulus or arc section is located at same straight line, can also be located in actual design
On same curve.
In the present embodiment, in order to further such that lens unit 1 go out the uniform no dark space of light intensity distributions, can be by two
11 mirror settings of optical texture, so that biggish side of annulus spacing is connected with each other in two optical textures 11.Light optical path out
Scheme the wide-angle refracted light intersection as shown in figure 4, can allow two optical textures 11 on the direction A-A after setting in this way, from
And the appearance of dark space is avoided, considerably increase light-emitting uniformity.And two optical textures 11 after connecting in this way, in B-B
The optical width that goes out on direction does not change, and the light length that goes out on the direction A-A increases, and it is long thus to further increase out light
The long and narrow property of degree.
In the present embodiment, the thickness of second part 112 allows for second part 112 and first part 111 than relatively thin in this way
Between thickness difference it is smaller, also than relatively thin, such thickness can generate the thickness of entire optical texture 11 on the direction A-A
More 80 ° of refracted lights, this light are more just easier to meet Europe rule function.
Embodiment 2
With reference to Fig. 5-8, the present embodiment the difference from embodiment 1 is that: the thickness of second part 112 is thicker, thus
So that the thickness difference between second part 112 and first part 111 is bigger, the thickness of entire optical texture 11 is also thicker,
Such thickness can generate more 45 ° of refracted lights on the direction A-A, and this light is more just easier to move backward
Lamp function.Rest part is same as Example 1, repeats no more.
Embodiment 3
With reference to Fig. 9-10, a kind of automobile lamp is provided in the present embodiment, comprising: pedestal 3, light source board 4 and lampshade 5；Institute
Cavity of the pedestal 3 with an accommodating light source board 4 is stated, the cavity is opening face close to the one side of 4 lamp source of light source board, described
Lampshade 5 is installed on the opening face, and the side of the lampshade 5 towards lamp source be disposed with it is a plurality of such as 1 institute of embodiment
The lens unit 1 of record.
Specifically, in the present embodiment, the lampshade 5 is strip, and the lens unit 1 is arranged in array, Mei Yipai
In lens unit be divided into two groups of left and right mirror settings by symmetry axis of the longitudinal axis of lampshade.
Embodiment 4
With reference to Figure 11-12, the present embodiment and the difference of embodiment 3 are: the lampshade 5 is circle, the lens unit 1
It is arranged in concentric loop, multiple lens units 1 is arranged on each annulus；And the lens unit 1 on the same annulus
It is divided into two groups of left and right mirror settings by symmetry axis of the longitudinal axis of lampshade 5.
In addition, the center point of the lampshade 5 is provided with the second lens 51, the concentric loop position that the lens unit 1 is formed
In the outside of second lens 51, and it is concentric with the second lens 51.
Embodiment 5
With reference to Figure 13-14, the present embodiment and the difference of embodiment 4 are: the lampshade 5 is circle, the lens unit 1
It is divided into two groups of left and right mirror settings by symmetry axis of the longitudinal axis of lampshade；1 split of lens unit in each group forms semicircle.
And what lens unit 1 was selected is the lens unit 1 in embodiment 2 in the present embodiment.
Embodiment 6
With reference to Figure 15-16, the difference of the present embodiment and embodiment 3-5 is, lamp source 2 is adopting surface mounted LED in embodiment 3-5
Light source, and Piranha formula LED light source is replaced in the present embodiment, rest part is identical with embodiment 3-5, in the present embodiment not
It repeats again.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
