This shape in one light distribution region 11 leads to light for the regional area for preventing the main energetic of light beam from concentrating in license plate
Strong non-uniform problem and raising optical efficiency are the most advantageous.In an embodiment of the present invention, the totality in the first light distribution region 11
The shape that first end 17 gradually broadens to second end 18 can be set into shape, and is not limited to triangle or trapezoidal shape, such as
It can be shape similar therewith (such as truncated triangles).
The technical effect of embodiment in order to better illustrate the present invention, present description provides it is assumed that light distribution device
Be not provided on 100 ' in the case where the first light distribution region 11 for the effect (as shown in Figure 7 and Figure 8) of light beam be equipped with first
Comparison of the light distribution device in light distribution region 11 for the effect (as shown in Figure 5 and Figure 6) of light beam.It can from Fig. 7 and Fig. 8
Out, in the case where being not provided with light distribution region on light distribution device 100 ', the energy for the light beam being irradiated in license plate 30 is concentrated on
A regional area (such as top of license plate) for license plate, such as the area surrounded in Fig. 8 by point A1, A2, A3, A4, A5 and A6
Domain.This may cause brightness disproportionation in license plate.And as can be known from Fig. 5 and Fig. 6, due to the work in the first light distribution region 11
With being distributed on bigger irradiated area in license plate 30 by the energy of the light beam of light distribution device 100, therefore can make
Light distribution in license plate 30 is more uniform.
As an example, the first light distribution region 11 is divided into the first subregion 111 and the second subregion 112.Such as Fig. 2 institute
Show, (i.e. towards (the lesser one end of width, such as triangle or ladder of first end 17 in first light distribution region 11 below dotted line x
Shape shaped top) one side) part be the first subregion 111, and (i.e. towards first light distribution region above dotted line x
One side of 11 second end 18 (biggish one end of width, such as triangle or trapezoidal shape bottom)) part be the second subregion
112.First subregion 111 can be arranged to receive the speck area of the light beam issued from light source.In general, the light beam issued from light source
Cross section in light distribution be not necessarily all it is ideal, it is that energy most collects that a region is often had in the cross section of light beam
