Description

Light reflection device, method of manufacturing the same, imaging member, and light processing system

Technical Field

The present application relates to the field of optical elements, and more particularly, to a light reflecting device, a method of manufacturing a light reflecting device, an imaging member, and a light processing system.

Background

With the development of automotive lighting technology, automotive headlamps have evolved from having only traditional lighting functions toward combining an adaptive high beam system (Adaptive Driving Beam, ADB) and ground projection functions. For example, during night driving, the car may have an ADB function; during the night, the automobile can also project different marks in front of the automobile so as to achieve the aim of human-automobile interaction.

In order to achieve both ADB and ground projection functionality, digital light processing (Digital Light Processing, DLP) headlamps based on intelligent controllable LED chips and based on digital micromirror devices (Digital Micromirror Device, DMD) are typically employed. DLP headlamps are the main stream of future intelligent headlamps. The light path of the DLP headlight comprises an imaging light path and an illumination light path, wherein the purpose of the illumination light path is to collimate and focus the light of the LEDs on the surface of the light reflecting device.

Light reflecting devices generally include reflective elements and other components. The reflective element is rectangular, and the focused spot of the illumination light path is difficult to match the shape of the reflective element, for example, is elliptical, so that in order to cover the reflective element with the elliptical spot, there will be spots around the reflective element that spill over the reflective element, and these spots impinge on components outside the reflective element. Light shining on these components will be reflected onto the projection image plane of the imaging light path, i.e. become stray light, which seriously affects the visual effect of the DLP headlight.

There is a need in the art for a light reflecting device that reduces or eliminates stray light reflected into the imaging light path region.

In addition, unless explicitly defined or contradicted by context, the particular steps included in the methods described herein are not necessarily limited to the order described, but may be performed in any order or in parallel. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Fig. 1 shows a schematic block diagram of an optical processing system according to an embodiment of the present application. Referring to fig. 1, an optical processing system provided in an embodiment of the present application includes: a light source 1, a collimation system 2, a mirror 3, a light reflecting means and a lens assembly 6. The light reflecting device comprises an imaging component 4 and a diaphragm 5. The imaging member 4 includes a reflective element 41 and a substrate 42.

The light source 1 is used for emitting light. The light source 1 may comprise an intelligent controllable LED chip, such as an EVIYOS LED chip. The light emitted by the light source 1 enters the collimation system 2.

The collimation system 2 is used for collimating the light rays emitted by the light source 1, so that the divergent light rays can be gathered more. The gathered bundles of rays have relatively defined boundaries, such as elliptical boundaries, and may be generally parallel propagating or have boundary dimensions that are designed as desired. The collected light beam is irradiated to the reflecting mirror 3.

The mirror 3 is arranged in the light path of the collimated light beam of the collimating system for directing the collimated light beam towards the light reflecting means, i.e. the incident light beam forming the imaging member 4. Specifically, the incident light beam generally covers the reflective element 41. Illustratively, the mirror is a free-form surface mirror, which can improve imaging quality.

The imaging component 4 may be a DMD chip, a liquid crystal on silicon (Liquid Crystal On Silicon, LCOS) chip, or other types of chips, for example. The DMD chip includes therein a digital micromirror array as the reflective element 41. The LCoS chip includes a liquid crystal panel serving as a reflective element 41 therein.

Referring to fig. 2, the diaphragm 5 may be a unitary body having an aperture 51. The aperture 51 of the diaphragm 5 is provided corresponding to the reflecting element 41 of the imaging part 4. Part of the light rays of the light beam reflected by the mirror 3 passes through the aperture 51 to strike the reflecting element 41, and the reflecting element 41 propagates the light beam L having the image information to the lens assembly 6 based on the received light rays. The light beam L with image information passes through the aperture 51 and then enters the imaging light path region of the lens assembly 6. Illustratively, the reflective element 41 is positioned within the aperture 5 such that the side of the reflective element 41 facing the lens assembly 6 is flush with the surface of the side of the diaphragm 5 facing the lens assembly 6, light rays impinge directly on the reflective element 41. Illustratively, the path of the light beam L propagating from the reflective element 41 towards the lens assembly 6 may be between the collimating system 2 and the mirror 3.

The light beam reflected by the mirror 3 normally covers the reflecting element 41 of the imaging part 4. The main central ray of the beam will now impinge on the reflecting element 41, whereas the edge rays of the beam will also impinge on the diaphragm 5. At least one diaphragm micro-reflection member is formed in a region outside the aperture 51 on a side of the diaphragm 5 facing the direction in which light is incident, and the diaphragm micro-reflection member of the diaphragm 5 is configured to propagate at least a part of these marginal rays in a direction away from the lens assembly 6, and at least a part of the rays reflected by the diaphragm micro-reflection member, or even all of them, do not enter an imaging optical path region of the lens assembly 6, thereby greatly reducing or even eliminating parasitic light.

Specifically, the diaphragm micro-reflection member is used to scatter light irradiated thereon in an incident light beam in a direction deviated from the aperture 51. The reflected light beam has a larger divergence angle, most of light rays deviate from the lens component 6, and a small part of light rays enter the lens component 6 to form stray light, but the light intensity of the stray light is greatly weakened, and imaging is hardly affected.

Illustratively, a diaphragm micro-reflective element may be used to reflect light impinging thereon in an incident light beam in a direction away from the aperture 51. Light impinging on the diaphragm micro-reflective member does not enter the imaging optical path of the lens assembly 6. The lens assembly 6 can adjust the light beam L with image information reflected by the reflecting element 41 to form imaging light, and then can project a pattern outside the light processing system provided by the application. The pattern may present image information such as logos or text. Furthermore, the light management system may be used for illumination after the reflective element 41 reflects all light impinging thereon to the lens assembly 6. It will be appreciated that the light beam L reflected by the reflecting element 41 may not carry specific information, but may be a light beam of different brightness. In this way the light processing system can meet different lighting requirements.

The light processing system provided by the embodiment of the application projects clear patterns, is little influenced by stray light, and has good imaging quality. In addition, the light treatment system is small in size and light in weight.

It will be appreciated that the marginal rays of the light beam reflected by the mirror 3 may also impinge on the substrate 42 of the imaging member 4 or on both the diaphragm 5 and the substrate 42.

In an alternative embodiment, the micro-reflection part may also be formed in the substrate 42, and in particular, at least one substrate micro-reflection part is provided at least at a portion of the side of the substrate 42 where the reflection element 41 is provided, except in a region where the reflection element 41 is provided. The substrate micro-reflective member is configured to deflect at least a portion of the light of the incident light beam that impinges on the substrate micro-reflective member away from the direction of propagation to the lens assembly 6. It will be appreciated that existing imaging components 4 may be assembled with matching engineered diaphragms 5 to provide the light reflecting device provided herein. Meanwhile, the integrated light reflecting device conforming to the application can be directly manufactured.

In another embodiment, the light reflecting means comprises a reflecting element 41, a substrate 42 and at least one light barrier. The light blocking plate is disposed outside the outer periphery of the reflecting element 41, and the micro-reflecting member is disposed at the light blocking plate. Part of the marginal rays in the incident beam impinges on the barrier which reflects the main stray light outside the imaging path of the lens assembly 6.

The light reflecting means may comprise, for example, two light barriers. The reflective element 41 is disposed on the substrate 42, which may have a rectangular shape. The upper side outer side and the lower side outer side of the reflecting member 41 are provided with light blocking plates, respectively. When light irradiated on the outside of the reflecting element 41 among the incident light beams is mainly irradiated on the upper side outside and the lower side outside of the reflecting element 41, a micro-reflecting member is provided on the light blocking plate. The barrier may reflect the main stray light outside the imaging path of the lens assembly 6. A small portion of the incident light beam may be irradiated to the left and right outer sides of the reflective element 41 and thus irradiated on the substrate 42. The light reflecting device can greatly reduce the influence of stray light on final imaging, and has the advantages of small volume, light weight and flexible installation.

The body of the diaphragm 5 may be, for example, a multi-piece splice. The diaphragm 5 may be fixed as one piece with the imaging member 4 or made as one piece. The diaphragm 5 may be located outside the outer periphery of the reflective element 41. For example, the body of the diaphragm 5 is disposed to be bonded to the outer periphery of the reflecting element 41. When the imaging element 4 is a DMD chip, the aperture 51 of the diaphragm 5 is smaller than the area constituted by all the digital micromirrors of the imaging element 4, and the digital micromirrors covered by the aperture 51 in the projection area on the imaging element 4 constitute the reflecting element 41. I.e. inside the outer periphery of the reflective element 41 is an effective light reflecting area.

Illustratively, the aperture 51 of the diaphragm 5 may have a side opening, for example the diaphragm 5 is "C" -shaped. The diaphragm 5 can be understood as having a light-shielding effect on its body, and a light-transmitting channel being provided outside its body.

The optical axis direction of the light beam L propagating through the reflecting element 41 is the working direction thereof, and is also the working direction of the light reflecting device. The reflecting element 41 is arranged to propagate a light beam L towards the lens assembly 6, which in operation adds information to the light beam L. In the exemplary embodiment, the light striking the reflective element 41 exceeds only a portion of the boundary of the reflective element 41. The diaphragm micro-reflecting member may be provided only at those non-effective light reflecting areas of the diaphragm 5 where light is irradiated.

The diaphragm micro-reflective member is adapted to reflect or deflect these light rays impinging thereon in a direction away from the lens assembly 6. The specific direction of deflection may be adjusted according to design. Alternatively, the deviation may be at a smaller angle, a larger angle, or a dispersed deviation.

The diaphragm micro-reflection component comprises a first reflection surface for reflecting light irradiated on the diaphragm micro-reflection component in an incident light beam, and the shape of the first reflection surface can be obtained by extending a first preset generatrix along a first preset direction. Specifically, the first preset direction may be a circumferential direction of the reflective element 41. The substrate micro-reflective member is the same. The form of the light-facing surface of the diaphragm micro-reflective element is, for example, extended by a first predetermined busbar, a part of which is used to form the first reflective surface. The first preset busbar is a morphological reference line forming the light-facing side surface of the diaphragm micro-reflective member. For example, when the diaphragm 5 is processed by photolithography or 3D printing, the first preset generatrix may be a processing reference line or a contour line, and form a first reflecting surface of the diaphragm micro-reflecting member in the extending direction. For example, when the diaphragm 5 is produced in one piece from a mold, the first predetermined busbar may be a machining reference line for the molding surface of the mold. The form of the first reflecting surface can also be obtained by extending the first preset bus in other directions. The first reflecting surfaces of the plurality of diaphragm micro-reflecting members may or may not extend in parallel. The form and the gesture of the first preset bus of the diaphragm micro-reflection parts can be the same or different.

The first preset busbar may be arc-shaped, zigzag-shaped, rectangular or trapezoidal. The light-receiving surface of the diaphragm micro-reflection part can also comprise a connecting surface besides the first reflection surface, and the connecting surface can also be obtained by extending a first preset bus. The first reflective surface of the diaphragm micro-reflective member may also be considered to comprise a plurality of regions having different reflective directions, and the first reflective surface may comprise at least one form of an arc, a zigzag, a rectangle or a trapezoid. The second reflective surface of the base micro-reflective member is the same.

A plurality of identical aperture micro-reflective members may be arranged in an array of micro-reflective members. Referring to fig. 2 to 3, a plurality of identical first diaphragm micro-reflective members 501 are aligned in a laminated manner into a first micro-reflective member array. Specifically, a plurality of identical diaphragm micro-reflective members are adjacently arranged in a micro-reflective member array, and an interval may be provided between the adjacent diaphragm micro-reflective members. In the arrangement direction, the size of the space is not larger than the size of the diaphragm micro-reflection member. Of course, different diaphragm micro-reflecting components can be arranged and combined into a micro-reflecting component array.

Illustratively, the first diaphragm micro-reflecting member 501 has a first reflecting surface 5011, and a plurality of first diaphragm micro-reflecting members 501 are arranged such that the extending directions of the first reflecting surfaces 5011 are parallel to each other. The first diaphragm micro-reflection member 501 has a smaller size in the arrangement direction and may have a longer expansion in the direction perpendicular to the arrangement direction. For example, the first preset generatrix P of the first diaphragm micro-reflective component 501 may extend along the direction of the straight line Q, the first preset generatrix P may include a first line segment P1 and a second line segment P2, the shape of the first reflective surface 5011 may be formed by extending the first line segment P1, and the shape of the connection surface may be formed by extending the second line segment P2.

The first preset generatrix P may also extend along a certain arc, for example along an arc centered or focused on the centre of the reflecting element 41. Such as a wave-like extension.

Reference is made to fig. 2 to 8. In the exemplary embodiment, the reflective element 41 of the imaging member 4 is rectangular, as is the aperture 51 of the corresponding diaphragm 5. The outer periphery of the reflecting element 41 includes four boundaries, which are a left side boundary, an upper side boundary, a right side boundary, and a lower side boundary, respectively. An array of micro-reflective elements is provided on the diaphragm 5 at the outer side of each boundary, each array of micro-reflective elements being arranged to propagate light rays in a direction away from the lens assembly 6.

Illustratively, the diaphragm micro-reflective member is disposed at least partially around the aperture 51.

In an exemplary embodiment, the surface of the diaphragm 5 facing the lens assembly 6 may be provided with an extinction film. Specifically, the surface of the diaphragm micro-reflection member facing the lens assembly 6 may be provided with an extinction film. Illustratively, the diaphragm 5 is provided with an extinction film only at the diaphragm micro-reflecting member. The matting film can further attenuate the effect of veiling glare on the final image.

In further exemplary embodiments, the diaphragm 5 disposed outside the outer periphery of the reflective element 41 may be disposed in conformity with the reflective element 41, and then the outer periphery of the reflective element 41 is disposed in conformity with the diaphragm micro-reflective member. The diaphragm micro-reflection member which is arranged in a fitting manner can better eliminate stray light caused by light outside the reflection element 41. A plurality of diaphragm micro-reflecting members may be provided at the non-effective light reflecting area of the diaphragm 5 irradiated with the light. Further, the entire light-facing surface of the diaphragm 5 may be provided with diaphragm micro-reflecting members.

In further exemplary embodiments, the present application provides an image forming member including a substrate 42 and a reflective element 41, and specifically, at least one micro-reflective member is provided at least a portion of a side of the substrate 42 where the reflective element 41 is provided, except in a region where the reflective element 41 is provided. The structure, shape and the like of the micro-reflection component, namely the substrate micro-reflection component are the same as those of the diaphragm micro-reflection component.

Illustratively, the micro-reflective member is disposed in close proximity to the reflective element 41.

In the exemplary embodiment, the imaging part 4 includes a substrate 42 and a reflective element 41 provided at one side of the substrate 42. At least one region of the substrate 42 located outside the reflective element 41 is provided with a matting film. Illustratively, the light-facing side of the second reflective surface of the base micro-reflective member is provided with an extinction film. Illustratively, the matting film is provided on the substrate 42 only at the substrate micro-reflective member.

Specific embodiments are described in detail below with reference to the accompanying drawings.

Example 1

Referring to fig. 1 to 3, the light reflecting device includes an imaging section 4 and a diaphragm 5, and a reflecting element 41 of the imaging section 4 has a rectangular shape. In fig. 2, the diaphragm 5 is shown with a front side along the visible side in the drawing, and with a back side on the other side. The front face is also the light-facing side surface of the diaphragm 5. Figure 3 shows a schematic isometric view of figure 2 at section A-A. The present embodiment is provided with a micro-reflection member, i.e., a first diaphragm micro-reflection member 501, in an area other than the aperture 51 of the diaphragm 5. Specifically, the first micro-reflection member array is disposed corresponding to the outside of the left boundary of the reflection element 41. In manufacturing the diaphragm 5, a plurality of first diaphragm micro-reflection members 501 may be formed by machining a plurality of grooves. Of course, it can also be manufactured in a stacked manner.

The light-facing side of the first diaphragm micro-reflective member 501 may be extended by a first predetermined busbar P of saw-tooth shape. The first predetermined busbar P may comprise, for example, two line segments extending out of the first reflecting surface 5011 and a connecting surface substantially perpendicular to the front surface of the diaphragm 5. The connection surface may also be recessed into the projected area of the first reflective surface 5011. The first reflecting surface 5011 may be a plane, and the normal line of the first reflecting surface 5011 is inclined to the left with respect to the optical axis of the light beam L so that the light irradiated thereon is reflected to the left, that is, deviated from the light reflected at the reflecting element 41 of the imaging part 4. Specifically, the projection of the reflected light ray onto the front surface of the diaphragm 5 is directed to the left, and an angle may be formed between the reflected light ray and the front surface of the diaphragm 5. So that the light rays impinging on the first diaphragm micro-reflective member 501 do not enter the subsequent imaging area together with the information-carrying light beam L.

The first reflecting surface 5011 extends longer in the upward and downward directions, and the length of the first reflecting surface 5011 can be arbitrarily set as required in the up-to-down direction.

For example, when the light spot to be fitted is substantially elliptical, the first diaphragm micro-reflection member 501, which is farther from the left boundary of the reflection element 41 of the imaging member 4, may have a smaller size in the up-down direction. Typically the edge extent of the first array of aperture micro-reflective elements is not smaller than the light to be processed.

The present embodiment is provided with a micro-reflecting member, that is, a second diaphragm micro-reflecting member 502, in an area other than the aperture 51 of the diaphragm 5. Specifically, the second micro-reflection member array is disposed corresponding to the outside of the upper side boundary of the reflection element 41. In manufacturing the diaphragm 5, a plurality of second diaphragm micro-reflection members 502 may be formed by machining a plurality of grooves. Of course, the second diaphragm micro-reflective member 502 may also be manufactured in a stacked manner.

The light-facing side of the second diaphragm micro-reflective member 502 may be extended by a predetermined busbar of saw-tooth shape. The predetermined busbar may comprise, for example, two line segments for extending the reflective surface 5021 and one connecting surface of the second stop micro-reflective component 502. The connection surface may also be recessed into the projection area of the reflective surface 5021 of the second stop micro-reflective member 502. The reflection surface 5021 of the second diaphragm micro-reflection member 502 may be a plane whose normal is inclined upward with respect to the optical axis of the light beam L so that the light rays irradiated thereon are reflected upward, i.e., deviated from the light rays reflected at the reflection element 41 of the imaging member 4. So that the light rays impinging on the second stop micro-reflective member 502 do not enter the subsequent imaging area together with the information-bearing light beam L.

The reflective surface 5021 of the second diaphragm micro-reflective member 502 extends long in the left and right directions.

For example, when the spot to be fitted is substantially elliptical, the second diaphragm micro-reflection member 502, which is farther from the upper side boundary of the reflection element 41 of the imaging member 4, may have a smaller size in the left-to-right direction. Typically the edge extent of the second array of micro-reflective elements is not less than the light to be treated.

The preset busbar may comprise, for example, two line segments for extending the morphology of the two reflecting surfaces of the third diaphragm micro-reflecting member 503. The two reflecting surfaces of the third diaphragm micro-reflecting member 503 scatter the light irradiated thereon. So that a large part of the light rays irradiated at the third diaphragm micro-reflecting member 503 do not enter the subsequent imaging area together with the light beam L with information. And even if a small part of the light rays reflected by the third diaphragm micro-reflection member 503 enter the imaging area, since these light rays have a large divergence angle, the influence of stray light at the time of imaging can be reduced.

The reflection surface of the third diaphragm micro-reflection member 503 extends in the left or right direction. The plurality of third diaphragm micro-reflection members 503 are arranged in the bottom-up direction to form a third micro-reflection member array such that light exceeding the upper side boundary of the reflection element 41 of the imaging member 4 is mostly scattered to deviate from light reflected at the reflection element 41 of the imaging member 4. For example, when the spot to be fitted is substantially elliptical, the third diaphragm micro-reflection member 503, which is farther from the upper side boundary of the reflection element 41 of the imaging member 4, may have a smaller size in the left-to-right direction. Typically the edge extent of the third array of micro-reflective elements is not less than the light to be treated.

The third diaphragm micro-reflective member 503 may extend arcuately in the left or right direction. The light rays irradiated at the reflecting surface of the third diaphragm micro-reflecting member 503 are reflected to be deviated from the optical axis of the light beam L to different degrees.

For example, at least one third diaphragm micro-reflection member 503 is provided on the upper side of the aperture 51. The first preset direction may be a bottom-up direction. The normal line of one reflecting surface 5031 of the third diaphragm micro-reflecting member 503 is inclined to the right, so that the light irradiated thereon is scattered in the normal line direction of the light-facing surface of the diaphragm 5, and the scattered light may have a large divergence angle to the right. The normal line of the other reflecting surface 5032 of the third diaphragm micro-reflecting member 503 is inclined to the left, so that the light irradiated thereto is scattered in the normal line direction of the light-facing surface of the diaphragm 5, where the scattered light may have a large divergence angle biased to the left.

For example, at least one third diaphragm micro-reflective member 503 is disposed on the left side of the aperture 51. The first preset direction may be a direction from lower right to upper left.

The predetermined generatrix may comprise, for example, two line segments for extending the form of the reflecting surface 5041 of the fourth diaphragm micro-reflecting element 504 and a connecting surface substantially perpendicular to the front face of the diaphragm 5. The connection surface may also be recessed into the projection area of the reflective surface 5041 of the fourth diaphragm micro-reflective member 504. The reflection surface 5041 of the fourth diaphragm micro-reflection part 504 may be a plane whose normal is inclined to the right with respect to the optical axis of the light beam L so that the light rays irradiated thereon are reflected to the right, i.e., deviated from the light rays reflected at the reflection element 41 of the imaging part 4. So that the light rays impinging on the fourth micro-reflective part 504 do not enter the subsequent imaging area together with the information-bearing light beam L.

The reflection surface 5041 of the fourth diaphragm micro-reflection member 504 extends longer upward and downward. The plurality of fourth diaphragm micro-reflection members 504 are arranged in the left-to-right direction to form a fourth micro-reflection member array such that light exceeding the right boundary of the reflection element 41 of the imaging member 4 is reflected to the right side while being deviated from light reflected at the reflection element 41 of the imaging member 4. Illustratively, when the spot to be fitted is substantially elliptical, the fourth diaphragm micro-reflection member 504, which is farther from the right-side boundary of the reflection element 41 of the imaging member 4, may have a smaller size in the up-down direction. Typically the fourth array of micro-reflective elements has an edge extent not less than the light to be treated.

The connection surface may also be substantially perpendicular to the front surface of the diaphragm 5 or at a negative angle, i.e. recessed into the projection area of the reflective surface 5051 of the fifth diaphragm micro-reflective member 505. The reflection surface 5051 of the fifth diaphragm micro-reflection member 505 may be a plane whose normal is inclined to the downward side with respect to the optical axis of the light beam L so that the light rays irradiated thereon are reflected to the downward side, i.e., deviated from the light rays reflected at the reflection element 41 of the imaging member 4. So that the light rays irradiated at the fifth micro-reflection part 505 do not enter the subsequent imaging area together with the light beam L carrying information.

The fifth diaphragm micro-reflection member 505 extends in the left or right direction. The plurality of fifth diaphragm micro-reflective members 505 are arranged in the top-down direction to form a fifth micro-reflective member array. So that light exceeding the boundary of the lower side of the reflecting element 41 of the imaging part 4 is reflected to the lower side while deviating from the light reflected at the reflecting element 41 of the imaging part 4. For example, when the spot to be fitted is substantially elliptical, the fifth diaphragm micro-reflection member 505, which is farther from the lower side boundary of the reflection element 41 of the imaging member 4, may have a smaller size in the left-to-right direction. Typically the edge extent of the fifth array of micro-reflective elements is not less than the light to be treated.
