Optical microstructures decorative pattern 3 between spacing it is identical；It is located at the described of the third row of 1 bottom of interior len on longitudinal direction
The size of optical microstructures decorative pattern 3 is greater than the size of the optical microstructures decorative pattern 3 of the second row, and every two adjacent
The every two adjacent optical microstructures decorative pattern 3 of the spacing of the optical microstructures decorative pattern 3 and the first row and the second row
Between spacing it is identical.
I.e. in terms of longitudinal direction, the size of the optical microstructures decorative pattern 3 of row from top to bottom is gradual change, but vertical
Sparse degree to the arrangement of the optical microstructures decorative pattern 3 of the row of direction from top to bottom is identical.Closer to the LED light
The size of the optical microstructures decorative pattern 3 of one row in source 2 is smaller, further away from the light of a row of the LED light source 2
The size for learning micro-structure decorative pattern 3 is bigger.The whole uniformity of the interior len 1 can be largely improved in this way.
The present embodiment have sweeping function, when LED light source 2 from close to vehicle body inner opposite end to vehicle body lateral ends realize by
A when lighting and extinguishing, corresponding realize of the present embodiment is equably sent out from close to vehicle body inner opposite end to vehicle body lateral ends in an orderly manner
Light.
The present embodiment is more efficient, and the energy conversion efficiency of light source to screen is higher, and it lights effect more evenly one
It causes, can satisfy luminous intensity distribution performance requirement of the regulation to the function signals lamp such as Brake lamp, optical system structure is simple, it can be achieved that function
It can multiplicity.
Embodiment three
The difference of embodiment three and embodiment one, embodiment two be embodiment third is that embodiment one and embodiment two combination.
As shown in figure 4, from the point of view of longitudinal direction, near the interior len top, i.e., near the LED light source 2
3 size of optical microstructures decorative pattern of first row is smaller, while the every two adjacent optical microstructures flower of the first row
Gap between line 3 is larger；It is located at the optical microstructures decorative pattern of second row at 1 middle part of interior len on longitudinal direction
3 sizes are greater than 3 size of optical microstructures decorative pattern of the first row, and the every two adjacent optical microstructures flower
The spacing of line 3 is smaller than the spacing between the every two adjacent optical microstructures decorative pattern 3 of the first row；It is located at institute on longitudinal direction
The size for stating the optical microstructures decorative pattern 3 of the third row of 1 bottom of interior len is greater than the micro- knot of the optics of the second row
