Specific implementation mode
The rear of a kind of uniformly light-emitting structure, including point light source 1, point light source 1 is equipped with principal reflection mirror 2, the front of point light source 1
Equipped with interior lens 4,4 outside of interior lens is equipped with case ring 5, is equipped between point light source 1 and interior lens 4 and keeps off case ring 5
Light firmly reflexes to auxiliary speculum 3 of the principal reflection mirror 2 far from 1 position of point light source, and the outside of case ring 5 is equipped with outer lens 6;
Principal reflection mirror 2 is equipped with dermatoglyph process layer 21 on the outer surface of the reflecting surface near close to sources;
The side to light of interior lens 4 is equipped with the first dermatoglyph process layer 45, and the shady face of interior lens 4 is equipped with the second skin
Line process layer 46.
Following form may be used in the structure of interior lens:
Embodiment 1:
Interior lens 4 includes base material, and base material includes scattering particles layer.Scattering particles layer is to include the scattering with DF materials
Particle layer.
Embodiment 2:
The base material of interior lens 4 is white clear base material or red, transparent base material, the side to light and shady face of interior lens 4
On be equipped with strip bulge decorative pattern.
The base material of interior lens 4 includes PC or PMMA materials.
It is equipped with process layer 22 of aluminizing on the reflecting surface of principal reflection mirror 2 and auxiliary speculum 3.The reflecting surface of principal reflection mirror 2
The reflecting surface of section indention, principal reflection mirror 2 includes several small reflectings surface, and small reflecting surface is formed by paraboloidal basal plane
Light distribution surface.
A kind of car headlight device, including uniformly light-emitting structure as described above, car headlight device can be automobile position
Set lamp.
It is a kind of scheme of prior art position lamp light distribution, after point light source 1 is lighted, light source is directed to principal reflection mirror such as Fig. 1
Light 7 by the reflex of principal reflection mirror 2 reach in lens 4, outer lens 6 is reached after the refraction of interior lens 4, then
Parallel lines 8 through principal reflection mirror reflection light 7 are projected by outer lens 6.Apart from light source remotely anti-wherein on principal reflection mirror 2
The incident ray that the face of penetrating obtains light source is less than reflecting surface closer apart from light source on speculum 2, causes light source brightness nearby apparent
Higher than far from light source part, ultimately form position lamp light it is uneven.
It is another scheme of prior art position lamp light distribution such as Fig. 2, auxiliary speculum 2 is arranged according to paraboloid, speculum
The longitudinal depth needed is larger, can not correspond to the limitation of the space design of smaller depth depth.
Such as Fig. 3, after point light source 1 is lighted, the light 7 that light source is directed to principal reflection mirror reaches principal reflection mirror 2, meanwhile, light source
The light 9 for being directed to auxiliary speculum forms the light that principal reflection mirror is reflexed to through auxiliary speculum by the reflex of auxiliary speculum 3
Line 10, and principal reflection mirror 2 is reached, two strands of light are simultaneously via lens 4 in the reflex directive of principal reflection mirror 2, then pass through interior

The parallel lines 11 of speculum reflection light 10.
The light 10 that principal reflection mirror is reflexed to through auxiliary speculum mends the light 7 that principal reflection mirror is directed to light source
It fills, to improve the light emission luminance apart from point light source remotely, to improve whole uniformity.
Principal reflection mirror 2 is equipped with dermatoglyph process layer 21 in 1 border of point light source, and direct light more near point light source 1 is carried out
Scattering, reduces the light emission luminance of 1 border of point light source, to improve whole uniformity.
Such as Fig. 3-5, interior light distribution, 4 when being white clear or red, transparent base material, reflects through principal reflection mirror 2 and matches in reaching
The light of light microscopic 4, the first dermatoglyph process layer 45 of the side to light 41 of lens in using white clear or red, transparent base material
Under the diffusion of strip projected parts decorative pattern, interior improvement of 4 first step of lens to light brightness unevenness is realized;Further,
Using the second dermatoglyph process layer 46 and strip projected parts decorative pattern of the shady face 42 of lens in white clear or red, transparent base material
Diffusion under, realize in improvement of the lens second step to light brightness unevenness, to realize that position lamp lights uniform hair
The effect of light.
Such as Fig. 3, Fig. 6 and Fig. 7, when interior lens 4 is using base material equipped with scattering particles layer, through the reflection of principal reflection mirror 2
The light of lens 4 in reaching is increased in scattering particles layer in using base material at the first dermatoglyph of the side to light 43 of lens
It manages in layer 45 and base material under the diffusion of scattering particles layer, realizes interior improvement of the lens first step to light brightness unevenness;
Further, increase the diffusion of the second dermatoglyph process layer 46 of the shady face 44 of lens in scattering particles layer in using base material
Under effect, interior improvement of 4 second step of lens to light brightness unevenness is realized, to realize that position lamp lights the effect of uniformly light-emitting
Fruit.
It should be appreciated that specific embodiment described above is only used for explaining the present invention, it is not intended to limit the present invention.By
