Description
Technical field
The utility model belongs to technical field of automobile illumination more particularly to a kind of signal with symmetrical guide structure
Lamp.
Background technique
With the development of economy, automobile home penetration rate is higher and higher, and requirement of the people to automobile is also not only to realize
It rides instead of walk demand, appearance and modeling is also increasingly paid close attention to.Currently, the moulding of car light is changeable, wherein light-emitting surface also gradually breaks through tradition,
Longer narrower visual effect is pursued, the high-mount brake lamp and taillight of many penetration types occurs.It is reflective to need LED number more,
Lighting has the effect of granular sensation.Currently, guide structure is widely used in automotive lighting field, LED number can be reduced, from
And whole lamp cost is reduced, it can be good at the granular sensation for eliminating LED, realize the uniformity of entire light-emitting surface, richer technology sense.And
Light can be elongated more and more weaker with distance in light guide internal communication, for present long light guide, the light guide knot of one end entering light
Structure is difficult to realize the brightness uniformity of tail portion and front end.And both ends entering light, before symmetrical guide structure is able to solve long light guide
Brightness uniformity problem afterwards improves light guide in the application in car light field.
Utility model content
The utility model is simple in order to solve a kind of structure, the signal with symmetrical guide structure of low manufacture cost
Lamp, can be realized long light guide lights uniformity, solves the problems, such as that not only narrow but also long light-emitting surface lights consistency effect, provides one
Signal lamp of the kind with symmetrical guide structure.
A kind of signal lamp with symmetrical guide structure, including shell are set gradually from inside to outside in the shell
There are bracket, light guide, interior lampshade and outer lampshade, the pcb board is vertically set on the both ends of the light guide, and the pcb board is equipped with
Light source, the light guide and the pcb board are symmetrical about central symmetry plane, and the light guide is equipped with light guide tooth close to one end of bracket.
Preferably, the uniformity in order to realize light, the light guide tooth from both ends to central symmetry plane from low to high,
By dredging close gradual change.
Further, in order to preferably expand range of refractive, light source is preferably utilized, two bevel edge of light guide tooth and tooth
The angle A and B that basal plane is formed are 0 °~45 °.
Preferably, the light source is 1 or plurality of LEDs.
Further, in order to realize the light-emitting uniformity realized in the unobstructed situation of light source, the both ends of the light guide are equipped with
Convex block, the convex block are equipped with tooth form, and the light guide is equipped with striated structure close to one end of interior lampshade, the tooth on the convex block
Light is totally reflected to the interior lampshade both ends by shape, realizes the uniformity of light.
Preferably, the uniformity in order to realize light, light is spread up and down, the sagitta of the striated structure is
0.1mm~1mm.
Further, the interior lampshade material is scattering material, such as: DF23, DF22 etc., the interior cover surface is flat
Face or pattern structure with diffusion improve the diffusivity of light, increase light luminance.
The utility model has the advantages that the light guide of the utility model is both ends entering light, both ends are symmetrical from the central position, one end LED every in this way
The length for the uniformity of being considered is the half of original light guide, reduces the height and density of light guide front-end optical tooth, reduces light
Light leakage in front end has enough light to guarantee the brightness at center, solves the problems, such as that long light guide center is dark when reaching center,
That realizes long light guide lights uniformity.

Specific embodiment
As shown in Figure 1, a kind of signal lamp with symmetrical guide structure, including shell 2, including shell 2, the shell
Bracket 4, light guide 1, interior lampshade 3 and outer lampshade 8 are disposed in body 2 from inside to outside, the pcb board 5 is vertically set on described
The both ends of light guide 1, the light source are 1 or plurality of LEDs, and the light guide 1 and the pcb board 5 are right about central symmetry plane 6
Claim, the light guide 1 is equipped with light guide tooth 9 close to one end of bracket 4.In order to realize the uniform in light emission realized in the unobstructed situation of light source
Property, the both ends of the light guide 1 are equipped with convex block 10, and the convex block 10 is equipped with tooth form, and the tooth form on the convex block 10 is by light
Line is totally reflected to the interior lampshade both ends, and the light guide 1 is equipped with striated structure, the striated structure close to one end of interior lampshade 3
Sagitta be 0.1mm~1mm.As shown in figure 4, the light guide tooth 9 from both ends to central symmetry plane 6 from low to high, by dredging
Close gradual change.In order to expand range of refractive, light source is preferably utilized, as it can be seen in figures 5 and 6, the light guide tooth 9 is double wedge or recessed
