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 has light incident side 21 and light exit side relative to each other
22.The light incident side 21 is used to receive the light beam 40 from light source 10, such as can be arranged towards light source 10.From light incident side 21
Inject, across light distribution device 20 light from light exit side 22 project.For example, the light exit side 22 can be arranged with backlight 10.
The multiple first light deflections portion 31 extended in parallel is provided on the light incident side 21 of light distribution device 20, and in light distribution device
The multiple second light deflections portion 32 extended in parallel, the multiple first light deflection portion 31 are provided on 20 light exit side 22
It is respectively used to receive the different piece of the light beam 40 from light source 10 and it is made to be deflected towards the second light deflection portion 32, it is the multiple
The each beam section deflected by the first light deflection portion 31 is carried out deviation by the second light deflection portion 32, to form light figure
Case.The angle of the extending direction in first light deflection portion 31 and the extending direction in the second light deflection portion 32 is more than zero (i.e. the two
It is not parallel).Reflected by the second light deflection portion 32, light beam with light pattern can be projected from car light, be used to form photograph
Bright 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 quadrangle patterns of amplification.Specifically, when light beam 40 is by the first light deflection portion 31, due to the deflection in the first light deflection portion 31
Effect, light beam 40 will be guided towards the second light deflection portion 32, and the cross-sectional shape of light beam 40 will become to be similar to one it is bright
Line.And the light beam 40 for being similar to a bright line to cross sectional pattern is extended by the refraction action in the second light deflection portion 32.By
In the extending direction out of plumb of the extending direction and the second light deflection portion 32 in the first light deflection portion 31, therefore, by light distribution device
After 20, light beam 40 can be extended and be shaped in two dimension, to form desired pattern, such as rectangle, parallelogram, water chestnut
Shape etc..When light source 10 includes a row point light source, one group of two-dimensional shapes may be formed by the light beam of photo-patterning device 100
Pattern, these shapes can be with overlapped.
As an example, when the angle of the extending direction of the extending direction and the second light deflection portion in first light deflection portion exists
When between 20 degree and 90 degree, the effect for being formed by pattern is more preferable.
As an example, the first light deflection portion 31 can realize the deflecting action of light beam by reflecting.For example, first
Light deflection portion 31 can have the surface profile of protrusion curved surface (such as cylindrical surface).This helps to gather light beam, improves optics effect
Rate.For example, the first light deflection portion 31 can guide the part of in light beam 40 70%, 80% or 90% even greater proportion to the
Two light deflection portions 32.
Since each first light deflection portion 31 may be different at a distance from light source 10, the first light deflection portion in addition
31 and second light deflection portion 32 for light beam refraction effect, from each second light deflection portion 32 project beam section light path
Between there will be differences.For example, as shown in Figure 1, it is incident through different the first light deflection portion 31, from the second different light deflection portions
32 beam sections projected can undergo different light paths.
Due to the difference of this light path, when observer's viewing is from (or the second light deflection portion 32 of each second light deflection portion 32
Different piece) project each beam section when, will produce 3 dimension visual effects.For example, in situation shown in Fig. 1, observation
Person may feel that the beam section projected from certain parts on the light exit side 22 of light distribution device 20 (such as is emitted from positioned at light
The beam section that the second light deflection portion 32 at 22 periphery of side projects) compared with other beam sections, it is to be sent out from farther position
Go out.Then, it visually may feel that there are depth feelings for pattern, in some instances it may even be possible to the bending that will produce pattern (such as line), from
And generate 3 dimension effects.
When light source 10 includes multiple point light sources, such as when a discharge optical diode, since different point light sources will cause not
Light path difference between each beam section of same light beam becomes apparent, thus, 3 dimension effects also will be more notable.
Light source 10 and the disposing way of light distribution device 20 may also can influence 3 dimension effects.For example, as shown in Figure 2 and Figure 4,
The extending direction in the second light deflection portion 32 can (such as Fig. 2 institutes vertical with the central axis 41 of light beam 40 sent out from light source 10
Show), it can also be with the central axis 41 of the light beam 40 sent out from light source 10 at inclination angle (such as shown in Fig. 4).By light distribution device
20 41 slant setting of central axis relative to light beam 40 is conducive to further increase from light source 10 to each second light deflection portion
Optical path difference (referring to Fig. 4) between each beam section between 32, so that from the second different light deflection portions 32 or the
3 dimension visual effects in the light beam of the different piece outgoing in two light deflection portions 32 are enhanced.Typically, which gets over
Greatly, 3 dimension visual effects are also stronger.
As an example, light distribution device 20 (or the extending direction in the second light deflection portion 32) can be sent out relative to from light source 10
Light beam 40 central axis 41 at the inclination angle at 20 degree to 70 degree of inclination angle, such as 30 degree to 60 degree, such as 45 degree of inclination
Angle.
As an example, the first light deflection portion 31 and the second light deflection portion 32 can be formed by cylindrical lens, i.e. the first light
The surface in deviation portion 31 and the second light deflection portion 32 can be formed by at least part on cylindrical surface.As shown in Figures 1 to 4.However
The invention is not limited thereto, and the first light deflection portion 31 and the second light deflection portion 32 can also have other shapes.
Fig. 3 shows illustrative refraction effect of the second light deflection portion 32 for light beam.The portion of illustrative light beam 40
Divide and be converged when passing through the second light deflection portion 32, but expands after convergent point and in the plane parallel with the paper of Fig. 3
It dissipates, to realize the extension for light beam.Since there may be a certain range of angle of departure and light distribution devices 20 for light source 10
Also uneven (being provided with the first light deflection portion 31), therefore the different piece of light beam 40 is in light distribution device on the surface of light incident side 21
Incidence angle on 20 light incident side 21 is different.To by each beam section in the first different light deflection portions 31 by edge
The different piece that each different direction reaches each second light deflection portion 32.Therefore, the second light deflection portion 32 is for light beam
Refraction can also be carried out on a variety of directions, such as the example of Fig. 3, the part of light beam 40 can also be in the paper with Fig. 3
Face in the plane at inclination angle at spreading.
Below by taking the second light deflection portion 32 with cylinder facial contour as an example, to the second light deflection portion 32 for beam section
Refraction further introduced.
Fig. 5 schematically shows single second light deflection portion 32, and (it is opposite with multiple first light deflections portion 31, it is assumed that the
Two light deflection portions 32 are vertical with the first light deflection portion 31).The second light deflection portion 32 is in the extension side with the second light deflection portion 32
Profile with part circular, the width in the second light deflection portion 32 in section on vertical direction (i.e. X-direction in Fig. 5)
Degree is d, the second light deflection portion on the top to the light exit side 22 in the first light deflection portion 31 on the light incident side 21
The distance of 32 root be H, the corresponding beam section sent out from light source 10 on light incident side 21, with the second light deflection portion
At the 32 corresponding position in center and the cross section in the second light deflection portion 32 incidence angle in the planes be α, light distribution dress
The Refractive Index of Material for setting 20 is n.In one example, a part of second light deflection portion 32 or all second light deflections portion 32 meet：
H×sinα/n<D/2 (formula 1)
Under conditions of meeting formula 1, the most of light being at least incident in the first light deflection portion 31 can be enable from
Two light deflection portions 32 project, in this way, when the observation of light exit side 22 in face of light distribution device 20, which is bright
, in other words, which is lit.When each second light deflection portion 32 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 second light deflections
Portion 32 all must satisfy formula 1, for example, incidence angle of the beam section that is sent out of light source 10 in each second light deflection portion 32 can
To differ, in this way, when the incidence angle of beam section is very big, corresponding to the second light deflection portion 32 may be just no longer full
Sufficient formula 1, at this moment, the intensity for the light being emitted from the second light deflection portion 32 will reduce, and be likely to form the dark areas in pattern.
It in other examples, can also be different to obtain to adjust the size in above-mentioned second light deflection portion 32 according to actual requirement
Bright dark areas.It should be noted that in an embodiment of the present invention, the first light deflection portion 31 can have curved surface, example
Such as cylindrical surface, in this way, can also be with by incident light of the beam section in the first light deflection portion 31 in the second light deflection portion 32
Plane where the paper of Fig. 5 at the inclination angle more than 0 and less than 90 degree, what this can promote to be emitted from the second light deflection portion 32
Diffusion and forming of the light beam in the plane vertical with the paper of Fig. 5.
As an example, the width d in each second light deflection portion 32 can be：
D=2 × H × arcsin (n × sin (arctan (H (n-1))/2r)) (formula 2)
Wherein r is the radius of curvature in the second light deflection portion 32.
As an example, the width d in the second light deflection portion 32 can be less than 5mm, preferably smaller than 0.15mm, such as can be big
In 0.01mm and less than 0.15mm or more than 0.05mm and less than 0.15mm or more than 0.1mm and it is less than 0.15mm.As showing
Example, the second light deflection portion 32 on the top to the light exit side 22 in the first light deflection portion 31 on the light incident side 21
The distance H of root can be 0.1mm to 5mm, be, for example, less than 0.3mm, such as 0.237mm.
In an embodiment of the present invention, the extending direction in the first light deflection portion 31 can be with the extension in the second light deflection portion 32
Direction is vertical, can also be with the extending direction in the second light deflection portion 32 at the angle more than 0 and less than 90 degree.For example, when first
When the extending direction in light deflection portion 31 is vertical with the extending direction in the second light deflection portion 32, it is more advantageous to raising optical efficiency, and
When the extending direction in the first light deflection portion 31 and the extending direction in the second light deflection portion 32 are at the angle more than 0 and less than 90 degree
When, be conducive to improve the diversity for being formed by pattern.
In one example, the radius of curvature of the cross-sectional profiles in the first light deflection portion 31 can be equal to second light deflection
The radius of curvature of the cross-sectional profiles in portion 32.However, in other examples, such as it is emitted from light distribution device 20 to change
The shape of the pattern of light beam is to improve visual effect (such as being allowed to more elongated or bending), the cross section in the first light deflection portion 31
The radius of curvature of profile can be more than or less than the radius of curvature of the cross-sectional profiles in second light deflection portion 32.
As an example, the multiple second light deflection portion 32 is disposed adjacent to one another on, as shown in Figure 1.This can improve from
The uniformity of the light intensity for the light beam that the multiple second light deflection portion 32 is emitted.Similarly, multiple first light deflections portion 31 also may be used
To be disposed adjacent to one another on.In one example, each first light deflection portion 31 or the second light deflection portion 32 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 example, such as in order to form the ruler of non-uniform pattern, each first light deflection portion 31 or the second light deflection portion 32
It is very little to can also be different, in addition can set between adjacent the first light deflection portion 31 or the second light deflection portion 32 it is certain between
Every.As an example, the size (shape etc. for including width, height, the plane of incidence and exit facet) in the first light deflection portion 31 can be with
Second light deflection portion 32 is identical, can also be different.
In the embodiment shown in fig. 1,31 setting spaced apart of light source 10 and the first light deflection portion, but the present invention
It is without being limited thereto.For example, light source 10 can be close to be arranged with the light incident side of light distribution device 20, as shown in Figure 6.This mode can be with
So that the certain first light deflections portion 31 and the distance between light source 10 on light distribution device 20 are as short as possible, and pass through different
First light deflection portion 31, the second light deflection portion 32 each beam section between optical path difference can be enlarged, to enhancing 3 dimension
Effect.For example, in figure 6, passing through the beam section of the middle section of light distribution device 20 can in the emergent light of light distribution device 20
Can it is shorter due to light path and give it is lofty sense it is stronger 3 dimension visual effect.
In one example, plane (the i.e. Fig. 2 of the light source 10 in the extending direction perpendicular to first light deflection portion 31
Paper where plane) in light emitting angle be more than 30 degree.Larger light emitting angle, which helps to increase, passes through different first
Light deflection portion 31, the second light deflection portion 32 each beam section between optical path difference, to improve 3 dimension effects.
As an example, the light source 10 may include one or more white lights or monochrome light emission diode.First
In the case that the width in light deflection portion 31 and the second light deflection portion 32 is relatively large compared with visible wavelength (such as in 0.1mm
More than), the first light deflection portion 31 and the second light deflection portion 32 do not interfere with emergent light for the color separation effect unobvious of white light
Visual effect.Therefore, which may be used white light emitting diode.The light source 10 may include a light-emitting diodes
The array of pipe or light emitting diode.Light source 10 can by it is well known in the prior art it is any for carry the component of light source Lai
Support, such as lamp holder, printed circuit board etc..
As an example, the light source 10 either point light source, can also be area source (such as can be by organic light emission two
Pole pipe (OLED) is made).As an example, the first light deflection portion 31 and the second light deflection portion 32 on light distribution device 20 can be with
Extend at lines form, for example, see Fig. 1.As an example, the light distribution device 20 can be integrated, work is made to simplify
Skill, and help to improve optical efficiency.For example, light distribution device 20 can be made of transparent glass, resin or plastic material, example
Such as PMMA (polymethyl methacrylate).The refractive index in the first light deflection portion 31 and the second light deflection portion 32 for example can be 1.3
To between 2.0.First light deflection portion 31 and the second light deflection portion 32 can be with refractive index having the same.It is examined for easy to make
Consider, can make the first light deflection portion 31 and the second light deflection portion 32 that there is same width.However, it's not necessary, for example,
In order to provide bigger optical design flexibility to form more abundant pattern, the width in the first light deflection portion 31 can be made
More than or less than the width in second light deflection portion 32.
Although illustrate only several first light deflections portion 31 and the second light deflection portion 32 in Figure of description, but it should reason
Solution, this is schematical, it is only for indicates clear, may be used more on light distribution device 20 in an embodiment of the present invention
More the first light deflection portions 31 and the second light deflection portion 32, such as tens of, hundreds of, even thousands of 31 and of the first light deflection portion
Second light deflection portion 32.
In one embodiment of this invention, the first light deflection portion 31 and the second light deflection portion 32 on the light distribution device 20
It can be formed by optical grating construction.In the case, each first light deflection portion 31 and the second light deflection portion 32 can correspond to
In a raster unit, the pitch of grating can be equal to the width in corresponding first light deflection portion 31 or the second light deflection portion 32.
Light distribution device 20 is formed using grating, manufacture craft and system structure can be simplified.It should be noted that grating is in optical system
It is commonly used in diffraction in system, but in the present invention, diffraction effect is not main.Especially, in the first light deflection portion 31 and
In the case that the width in two light deflection portions 32 is relatively large compared with visible wavelength (such as in 0.1mm or more), the first light is inclined
Folding part 31 and the second light deflection portion 32 are mainly that 3 required dimension display effects are realized by reflecting.This with it is in the prior art
Application on the ordinary meaning of grating has very big difference.
The embodiments of the present invention also provide it is a kind of include the photo-patterning device 100 as described in above-mentioned any embodiment
