Light exit surface is stated to arrange backwards to the light source.
In addition, in the following detailed description, for ease of explaining, elaborating many concrete details to provide to present disclosure
The comprehensive understanding of embodiment.It should be apparent, however, that one or more embodiments also may be used without these specific details
To be carried out.
Fig. 1 schematically shows the photo-patterning device 100 of an embodiment according to the present invention.The photo-patterning device
100 include：Light source 10 and light distribution device 20.The light distribution device 20 may include the multiple light deflection portions 30 extended in parallel, institute
Multiple light deflection portions 30 are stated to be respectively used to receive and reflect the different piece of the light beam 40 from light source 10.Each light deflection
There is light incident surface 31 and light exit surface 32, the light incident surface 31 to be arranged towards the light source 10 in portion 30, the light
Exit surface 32 is arranged backwards to the light source 10.The part of the light beam 40 reflected by light deflection portion 30 can be projected from car light,
It is used to form illumination and/or signal designation light beam.
By means of photo-patterning device 100 according to an embodiment of the invention, the patterning to light beam may be implemented.Example
Such as, when light source 10 is a point light source (such as light emitting diode), one may be formed by the light beam of photo-patterning device 100
The pattern of bright line.When light source 10 include a row point light source when, by the light beam of photo-patterning device 100 may be formed one group it is bright
The pattern of line.
In one example, at least one of the multiple light deflection portion 30 is between light deflection portion 30 and the light source 10
Light path can and other light deflection portions 30 it is different from the light path between the light source 10.For example, in the multiple light deflection portion 30
At least one light deflection portion 30 light incident surface 31 and the distance between the light source 10 and other light deflection portions 30 light
Incidence surface 31 is different from the distance between the light source 10.As shown in Figure 1, the light deflection positioned at 20 middle section of light distribution device
Portion 30 is different at a distance from the light deflection portion 30 to light source 10 of 20 upper and lower ends of light distribution device.
Since the light incident surface 31 and the distance between light source 10 in each light deflection portion 30 are not necessarily all identical, work as observer
Viewing from each beam section that the light exit surface 32 in each light deflection portion 30 projects when, will produce 3 dimension visual effects.Example
Such as, in situation shown in Fig. 1, even if each light deflection portion 30 is arranged side by side, observer may feel that by being located at light distribution
The beam section in the light deflection portion 30 of 20 upper and lower ends of device and the light deflection portion 30 by being located at 20 middle section of light distribution device
Beam section compare, sent out from farther position.Then, it visually may feel that there are depth feelings for pattern, even
The bending of pattern (such as line) may be will produce, to generate 3 dimension effects.
Light source 10 and the disposing way of light distribution device 20 may also can influence 3 dimension effects.For example, as shown in Figures 2 to 4, light
Plane where the light incident surface 31 in deviation portion 30 can (example vertical with the central axis 41 of light beam 40 sent out from light source 10
It as shown in Figure 2), can also be with the central axis 41 of the light beam 40 sent out from light source 10 at inclination angle (such as Fig. 3 and Fig. 4 institutes
Show).41 slant setting of central axis by light distribution device 20 relative to light beam 40 is conducive to increase each light deflection portion 30 and light
The distance between source 10 difference (referring to Fig. 3), so that being obtained from 3 dimension visual effects in the light that each light deflection portion 30 is emitted
Enhancing.Typically, the angle of inclination is bigger, and 3 dimension visual effects are also stronger.As an example, the light in all light deflection portions 30 enters
Reflective surface 31 can be generally aligned in the same plane, but it's not necessary, such as the light incident surface 31 in each light deflection portion 30 also may be used
There is angle each other.
As an example, the light distribution device 20 formed by multiple light deflection portions 30 of parallel arranged can be relative to from light source 10
The central axis 41 of the light beam 40 sent out at 20 degree to 70 degree of inclination angle, such as 30 degree to 60 degree inclination angle, such as 45 degree
Inclination angle.
As an example, the multiple light deflection portion 30 is disposed adjacent to one another on, as shown in Figure 1.This can be improved from described
The uniformity of the light intensity for the light beam that multiple light deflection portions 30 are emitted.In one example, each light deflection portion 30 can have same
Size (shape etc. for including width, height, the plane of incidence and exit facet), this contributes to form the pattern of continuous uniform.However,
In other examples, such as in order to form non-uniform pattern, the size in each light deflection portion 30 can also be different, or even
Certain interval can be set between adjacent light deflection portion 30.
Below by taking exit facet is the light deflection portion 30 of arc surface as an example, the operation principle in light deflection portion 30 is carried out briefly
It introduces.
Fig. 5 schematically shows single light deflection portion 30.The light exit surface 32 in the light deflection portion 30 with light deflection
Profile with part circular in section on the vertical direction (X-direction i.e. in Fig. 1 and Fig. 5) of the extending direction in portion 30, should
The width in light deflection portion 30 is d, and the distance of the light incident surface 31 to the root of the light exit surface 32 is H, from light source
Incidence angle of the 10 corresponding beam sections sent out at the center of light incident surface 31 is α, and the material in light deflection portion 30 reflects
Rate is n.In one example, the light deflection portion 30 can meet：
H×sinα/n<D/2 (formula 1)
Under conditions of meeting formula 1, the most of light being at least incident on light incident surface 31 can be enable from the light
The light exit surface 32 in deviation portion 30 projects, in this way, when the observation of light exit surface 32 in face of light deflection portion 30, the light deflection
Portion 30 is bright, and in other words, which is lit.When each light deflection portion 30 is satisfied by formula 1, match
Electro-optical device 20 is whole will to be presented uniform bright pattern.However, in an embodiment of the present invention, however it is not limited to all light deflection portions 30
Formula 1 is all must satisfy, for example, incidence angle of the beam section that is sent out of light source 10 in each light deflection portion 30 can not phase
Together, in this way, when the incidence angle of beam section is very big, corresponding to light deflection portion 30 just may no longer meet formula 1, this
When, the intensity for the light being emitted from the light deflection portion 30 will reduce, and be likely to form the dark areas in pattern.In other example
In, according to actual requirement different bright dark areas can also be obtained to adjust the size in above-mentioned light deflection portion 30.
As an example, the width d in each light deflection portion 30 can be：
D=2 × H × arcsin (n × sin (arctan (H (n-1))/2r)) (formula 2)
Wherein r is the radius of curvature of light exit surface 32.
As an example, the width d in light deflection portion 30 can be less than 5mm, preferably smaller than 0.15mm, such as can be more than
0.01mm and less than 0.15mm or more than 0.05mm and less than 0.15mm or more than 0.1mm and be less than 0.15mm.As an example,
The distance H of the light incident surface 31 to the root of the light exit surface 32 can be 0.1mm to 5mm, be, for example, less than
0.3mm, such as 0.237mm.
In embodiment as described above, the light exit surface 32 is in the side vertical with the extending direction in light deflection portion 30
There is arc-shaped profile, however, the present invention is not limited thereto in upward section.Light exit surface 32 can also have other any shapes
The profile of shape, for example, can in section of the light exit surface 32 on the direction vertical with the extending direction in light deflection portion 30
With the profile with triangle, as shown in Figure 6.
In the embodiment shown in fig. 1, light source 10 and 30 setting spaced apart of light deflection portion, but the present invention is unlimited

As shown in Figure 7.This mode can so that the distance between certain light deflection portions 30 and light source 10 on light distribution device 20 to the greatest extent may be used
Can be short, to 3 dimension effect of enhancing.For example, in the figure 7 between the light deflection portion 30 and light source 10 of the middle section of light distribution device 20
Distance in the light deflection portion 30 of upper and lower ends part and the gap and Fig. 1 of the distance between light source 10 of light distribution device 20
Example compares bigger, thus stronger from 3 dimension effects in the light beam that light deflection portion 30 is emitted.
In one example, photo-patterning device 100 can also include optical collimator 50, as shown in Figure 4.The optical collimator
50 between the light source 10 and light distribution device 20, for being collimated to the light beam 40 sent out from light source 10.Optical collimator
50 setting can play the role of expanding the light-emitting area of light source 10, for example, when light source 10 is point light source, optical collimator 50
Area source can be converted it into.Broader pattern can be being formed from the light beam that light distribution device 20 is emitted (such as more in this way
Wide line).As an example, optical collimator 50 can be lens or can realize any suitable of optical alignment in the prior art

Row beam pattern, and the light diffusing member 52 is capable of the range of exposures of expanded light beam, to preferably improve the uniformity of light intensity
With 3 dimension effects.As an example, light diffusing member 52 can also be arranged between optical collimator 50 and light distribution device 20, such as can
To be light diffusing sheet.
In one example, the light source 10 is in the plane perpendicular to the light deflection portion 30 and the central axis of light beam 40
Light emitting angle in (plane i.e. where the paper of Fig. 1) is more than 30 degree.Larger light emitting angle helps to keep different light inclined
