Description

Technical Field

[0001] The present invention relates to a lighting device, and in particular to a pixelated lighting device for a vehicle. In addition, the present invention also relates to a vehicle lamp and a vehicle. Background Art

[0002] In recent years, with the development of the automotive lighting industry, single-source road lighting has become insufficient to meet the safety and comfort needs of road users. Pixelated lighting devices, which simultaneously implement matrix lighting and pixel displays, are increasingly being used in vehicle lighting technology. In practice, pixelated light patterns are often superimposed with non-pixelated light patterns, resulting in a certain overlap area and overlap boundary. Figure 1 and Figure 2 The light shape diagram is a superposition of a pixelated light shape and a non-pixelated light shape formed by a pixelated lighting device, wherein: Figure 1 is a schematic diagram of the light shape in high beam lighting mode, Figure 2 is a schematic diagram of the light shape in the low beam lighting mode, Figure 1 and Figure 2 In the figure, a is a pixelated light shape, b is a non-pixelated light shape (an auxiliary low-beam light shape used for low-beam widening lighting), c is the superimposed boundary of the pixelated light shape a and the non-pixelated light shape b, and d is the low-beam cutoff line.

[0003] Figure 3 and Figure 4 The following is a schematic diagram of a pixelated light pattern formed by a pixelated lighting device in the prior art and a simulated light pattern of a vehicle headlight equipped with the prior art pixelated lighting device. In the figure, a1 is the prior art pixelated light pattern, and c1 is the prior art superposition boundary, i.e., the lower boundary area of ​​the prior art pixelated light pattern a1. Figure 3 and Figure 4 It can be seen that the boundary of the pixelated light shape a1 formed by the pixelated lighting device in the prior art is too sharp, resulting in uneven transition and poor connectivity at the boundary after the pixelated light shape is superimposed with the non-pixelated light shape.

[0053] In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," and "right" and the like, indicating directions or positional relationships, are used solely to facilitate description and simplify the present invention, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. The terms "upper," "lower," "left," and "right" are based on the directions or positional relationships shown in the corresponding drawings, "front" refers to the direction in which light is emitted, and "rear" refers to the direction opposite to "front."

[0054] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0055] A first aspect of the present invention provides a vehicle pixelated lighting device. The vehicle pixelated lighting device of the basic embodiment of the present invention includes a pixelated lighting light source 5 and a lens group 1. The lens group 1 includes at least two lenses arranged in sequence along the light emission direction of the pixelated lighting light source 5. The pixelated lighting light source 5 includes a plurality of light-emitting units 51 arranged in a matrix. The light-emitting surfaces 511 of the plurality of light-emitting units 51 constitute an overall light-emitting surface. A shielding member having a plurality of light-transmitting micropores 61 is provided between the pixelated lighting light source 5 and the lens group 1, so that light emitted from the boundary portion of the upper area of ​​the overall light-emitting surface can be emitted through the light-transmitting micropores 61 on the shielding member, wherein the boundary portion of the upper area of ​​the overall light-emitting surface at least includes its upper boundary portion.

[0056] In the above basic embodiment, the light emitted by the pixel lighting light source 5 can form a pixelated light shape after being emitted through the lens group 1, and the light emitted from the boundary portion of the upper area of ​​the overall light-emitting surface can form the lower boundary area of ​​the pixelated light shape after being emitted through the lens group 1. By providing a shielding member having a plurality of light-transmitting micro-holes 61 between the pixel lighting light source 5 and the lens group 1, the light emitted from the boundary portion of the upper area of ​​the overall light-emitting surface can be emitted through the light-transmitting micro-holes 61 on the shielding member. It should be noted here that not all light can be emitted through the light-transmitting micro-holes 61. A portion of the light is blocked by the area outside the light-transmitting micro-holes 61, and the light emitted through the light-transmitting micro-holes 61 will produce diffraction, thereby making the lower boundary area of ​​the formed pixelated light shape softer, so that when the pixelated light shape and the non-pixelated light shape are superimposed, the transition at the superimposed boundary is uniform and better connected. Among them, the upper boundary part of the upper area of ​​the overall light-emitting surface, the left boundary part of its upper area and the right boundary part of its upper area all belong to the boundary part of the upper area of ​​the overall light-emitting surface, and the lower boundary part of its upper area does not belong to the boundary part of the upper area; the lower boundary area of ​​the pixelated light shape includes its lower boundary, lower left boundary and lower right boundary, and the lower boundary has the greatest influence on the superimposed boundary of the pixelated light shape and the non-pixelated light shape. Therefore, at least the light emitted from the upper boundary part of the upper area of ​​the overall light-emitting surface must be able to be emitted through the light-transmitting micropores 61 on the shielding member to soften the lower boundary of the pixelated light shape, so that the pixelated light shape and the non-pixelated light shape have a uniform transition and better connection at the superimposed boundary.

[0057] Figure 15 This is a schematic diagram of the pixelated light shape formed by the vehicle pixelated lighting device of the present invention. As can be seen from the figure, the lower boundary area of ​​the pixelated light shape a2 of the present invention, that is, the superimposed boundary c2 of the present invention superimposed with the non-pixelated light shape, has a more dispersed light energy distribution and a softer boundary than its upper area, making the transition between the pixelated light shape a2 and the non-pixelated light shape more uniform. Figure 16 This is a schematic diagram of the simulated light shape of the road surface of the vehicle lights using the vehicle pixelated lighting device of the present invention. As can be seen from the figure, the superposition boundary c2 of the present invention becomes less obvious, and the transition between the pixelated light shape and the non-pixelated light shape at the superposition boundary c2 is more uniform and better connected.

[0058] In order to facilitate understanding of the basic implementation of the present invention, further description will be given below in conjunction with specific structures.

[0059] Specifically, the shielding member is configured to cover the upper boundary portion of the upper region of the entire light-emitting surface, the left boundary portion of the upper region, and the right boundary portion of the upper region. Figure 8As shown, the shielding member can be configured to cover the entire light-emitting surface 511 of the nth row of light-emitting units 51 located on the upper side, or the entire light-emitting surface 511 of the nth-1th row of light-emitting units 51 located on the upper side, and the upper portion of the light-emitting surface 511 of the nth row of light-emitting units 51 located on the upper side (i.e., the upper boundary portion of the upper region of the overall light-emitting surface), and simultaneously cover the entire light-emitting surface 511 of the mth column of light-emitting units 51 located on the left side, or the entire light-emitting surface 511 of the mth-1th column of light-emitting units 51 located on the left side, and the left portion of the light-emitting surface 511 of the mth column of light-emitting units 51 located on the left side (i.e., the left boundary portion of the upper region of the overall light-emitting surface), and simultaneously cover the entire light-emitting surface 511 of the light-emitting units 51 located on the right side, or the entire light-emitting surface 511 of the light-emitting units 51 on the right side, and the right portion of the light-emitting surface 511 of the sth column of light-emitting units 51 on the right side (i.e., the right boundary portion of the upper region of the overall light-emitting surface), that is, the shielding member is configured to be in an inverted concave shape. Figure 9 The figure shows a specific arrangement of the shielding member, in which the shielding member covers the upper portion of the light-emitting surface 511 of the topmost row of light-emitting units 51, the left portion of the light-emitting surface 511 of the leftmost column of light-emitting units 51, and the right portion of the light-emitting surface 511 of the rightmost column of light-emitting units 51. By setting the shielding member in an inverted concave shape, the entire lower boundary area of ​​the pixelated light shape can be softened, so that the transition at the overlapping boundary with the non-pixelated light shape is more uniform and the connection is better. Of course, the shielding member can also be set to cover only the upper boundary portion of the upper area of ​​the entire light-emitting surface to soften the lower boundary of the pixelated light shape; or it can be set to cover both the upper boundary portion of the upper area of ​​the entire light-emitting surface and the left boundary portion of the upper area of ​​the entire light-emitting surface to soften the lower boundary and the lower right boundary of the pixelated light shape; or it can be set to cover both the upper boundary portion of the upper area of ​​the entire light-emitting surface and the right boundary portion of the upper area of ​​the entire light-emitting surface to soften the lower boundary and the lower left boundary of the pixelated light shape.

[0060] Preferably, if Figure 14As shown, the distance L between the light-emitting surface 511 of the light-emitting unit 51 and the shielding member is less than or equal to 5 mm, preferably less than or equal to 2 mm, and more preferably less than or equal to 0.5 mm. Preferably, the light-transmitting microholes 61 are circular holes, and the diameter of the circular holes is less than or equal to 1 mm, preferably less than or equal to 0.2 mm, so that the diffraction effect can be enhanced. Among them, the light-transmitting microholes 61 are set as circular holes to make processing simpler. Of course, they can also be set as microholes of other shapes, such as square holes, elliptical holes, or diamond holes. Preferably, the shielding member is a microporous plate 6, and the microporous plate 6 is made of metal material. The microporous plate 6 is a plate member with several light-transmitting microholes 61, and the thickness of the microporous plate 6 is less than or equal to 1 mm, preferably less than or equal to 0.5 mm. The size setting of the microporous plate 6 can ensure better imaging effect. If the thickness of the microporous plate 6 is too large, it will affect the amount of light emitted from the light-transmitting microholes 61, thereby affecting the imaging effect. The above preferred embodiment can better ensure the imaging effect of pixelated light.

[0061] Further preferably, the surface of the shielding member near the lens group 1 is provided with an aluminum coating. By providing the aluminum coating, the reflectivity of the light reflected back to the shielding member surface by the lens group 1 can be increased, thereby further improving the light softness at the boundary where the pixelated light shape and the non-pixelated light shape overlap.

[0062] like Figure 8 As shown, the pixel lighting source 5 includes multiple single-pixel light-emitting units 51 arranged in a matrix. The pixel lighting source 5 is preferably a Micro LED light source, i.e., a miniature LED light source. Each light-emitting unit 51 in the Micro LED light source is a micron-sized LED light-emitting unit. The Micro LED light source is a rectangular array LED light source composed of tens of thousands of micron-sized LED light-emitting units. The use of a Micro LED light source can make the pixels smaller and denser, thereby increasing the clarity of the pixel image formed. This allows for more precise control of the pixelated light shape formed after the pixel image is projected. The resulting dark area boundaries and changes in dark area positions are also more precise and smooth, which can better avoid glare or blinding to pedestrians or drivers. Furthermore, the rectangular array can produce a wider light pattern to illuminate areas on both sides of the road, facilitating the driver's observation of pedestrians and road signs on both sides of the road.

[0063] Specifically, if Figures 10 to 13As shown, the lens group 1 includes a first lens 11, a second lens 12, and a third lens 13 arranged in sequence along the light emitting direction of the pixel illumination light source 5. The first lens 11 is a concave-convex lens. The first lens 11 includes an inwardly concave light incident surface and an outwardly convex light exit surface, and the convexity of the light exit surface is greater than the concavity of the light incident surface. The first lens 11 is close to the pixel illumination light source 5. By providing the inwardly concave light incident surface and the outwardly convex light exit surface, more light can be converged to the second lens 12, thereby improving the utilization rate of light. The second lens 12 is a convex-concave lens. The second lens 12 includes a light-entry surface that is concave at the periphery and convex in the middle, and a light-exit surface that is convex at the periphery and concave in the middle. The concavity of the light-exit surface is greater than the convexity of the light-entry surface, which can diverge the light and is used to balance the aberrations in the optical system, avoid the appearance of distorted virtual images, and affect the resolution of the imaging. The third lens 13 is a biconvex lens with both the light-entry surface and the light-exit surface convex. The third lens 13 is close to the image side and can converge the light to project the light to form a pixelated light shape. The arrangement of the first lens 11, the second lens 12, and the third lens 13 is conducive to balancing the aberrations of the optical system and ensuring the clarity of the imaging. The Abbe numbers of the first lens 11 and the third lens 13 are both greater than the Abbe number of the second lens 12. This arrangement is conducive to eliminating chromatic aberration. The Abbe number is an index used to represent the dispersion ability of a transparent medium. Generally speaking, the greater the refractive index of the medium, the greater the dispersion and the smaller the Abbe number; conversely, the smaller the refractive index of the medium, the less dispersion and the larger the Abbe number. Preferably, the first lens 11 is made of glass, the second lens 12 is made of PC (polycarbonate), and the third lens 13 is made of PMMA (polymethyl methacrylate).

[0064] Specifically, if Figures 5 to 7 As shown, the vehicle pixelated lighting device further includes a lens holder 2, a circuit board 3, and a radiator 4. The first lens 11, the second lens 12, and the third lens 13 are all mounted within the lens holder 2. The pixelated lighting source 5 and the shielding member are both mounted on the circuit board 3. The lens holder 2, the circuit board 3, and the radiator 4 are sequentially fixedly connected by screws 42. The shielding member can also be fixed to other components, such as the lens holder 2. The radiator 4 is preferably an air-cooled radiator, with a cooling fan 41 mounted on the rear side of the radiator 4.

[0065] More specifically, if Figure 10As shown, the outer circumferential surfaces of the first lens 11, the second lens 12 and the third lens 13 all abut against the inner wall surface of the lens holder 2, and the three lenses are circumferentially limited by the inner wall surface of the lens holder 2; one end of the lens holder 2 is provided with a limiting portion 24, and the other end is provided with a beam limiting member, and the inside of the lens holder 2 is provided with a first limiting ring 21 and a second limiting ring 22, and the outer circumferential surfaces of the first limiting ring 21 and the second limiting ring 22 all abut against the inner wall surface of the lens holder 2, the first lens 11 is arranged between the limiting portion 24 and the first limiting ring 21, and the first lens 11 is limited forward and backward by the limiting portion 24 and the first limiting ring 21; the second lens 12 is arranged between the first limiting ring 21 and the second limiting ring 22, and the second lens 12 is limited forward and backward by the limiting portion 24 and the first limiting ring 21; The second lens 12 is limited forward and backward by the first limiting ring 21 and the second limiting ring 22; the third lens 13 is arranged between the second limiting ring 22 and the beam limiting member, and the third lens 13 is limited forward and backward by the second limiting ring 22 and the beam limiting member, so that the first lens 11, the second lens 12 and the third lens 13 are limited and fixed in the lens holder 2, so that each lens is tightly arranged in the lens holder 2, which can effectively reduce the overall volume and facilitate miniaturization design; and, compared with only limiting the front and back positions of each lens by forming a limiting structure by the lens holder 2 itself, by setting the first limiting ring 21, the second limiting ring 22 and the beam limiting member to limit the front and back positions of each lens, the manufacturing precision requirements of the lens holder 2 can be reduced, and the production cost can be reduced. Among them, the limiting portion 24 is a step structure formed at one end of the lens holder 2. The limiting portion 24 cooperates with the light incident surface and the outer peripheral surface of the first lens 11. On the one hand, it can abut against the outer peripheral surface of the first lens 11 to circumferentially limit the first lens 11. On the other hand, it can abut against the periphery of the light incident surface of the first lens 11, so that the first lens 11 can be used as an installation reference, which is convenient for the sequential installation of the second lens 12 and the third lens 13. The setting of the beam limiting member is used to block the light that will form stray light, which is conducive to eliminating stray light. The beam limiting member is preferably an aperture 23, and the aperture 23 is detachably fixed to the lens holder 2, such as by threading or snapping. During installation, the first lens 11, the first limiting ring 21, the second lens 12, the second limiting ring 22 and the third lens 13 are installed in the lens holder 2 in sequence, and finally the aperture 23 is installed on the lens holder 2 to press the components into place.

[0066] As a specific embodiment, the vehicle pixelated lighting device of this embodiment includes a pixel lighting light source 5, a lens group 1, a lens holder 2, a circuit board 3 and a radiator 4. The lens group 1 includes a first lens 11, a second lens 12 and a third lens 13 arranged in sequence along the light emission direction of the pixel lighting light source 5. The first lens 11 is a concave-convex lens, which includes a concave light incident surface and a convex light exit surface. The second lens 12 is a convex-concave lens, which includes a light incident surface with a concave periphery and a convex middle and a light exit surface with a convex periphery and a concave middle. The third lens 13 is a biconvex lens with both the light incident surface and the light exit surface convex. The first lens 11, the second lens 12 and the third lens 13 are all installed in the lens holder 2. The pixel lighting light source 5 includes a plurality of light-emitting units 51 arranged in a matrix. A microporous plate 6 is provided between the pixel lighting light source 5 and the first lens 11. The pixel lighting light source 5 and the microporous plate 6 are both installed on the circuit board 3. The lens holder 2, the circuit board 3 and the radiator 4 are fixedly connected in sequence by screws 42. The microporous plate 6 is configured to simultaneously cover the upper boundary portion of the upper area of ​​the entire light-emitting surface, the left boundary portion of the upper area, and the right boundary portion of the upper area, so that the light emitted from the light-emitting surface 511 of the above-mentioned light-emitting unit 51 can be emitted through the light-transmitting micropore 61. The light emitted through the light-transmitting micropore 61 and the light directly emitted through the light-emitting surface 511 of other light-emitting units 51 are projected out after passing through the first lens 11, the second lens 12, and the third lens 13 in sequence to form a pixelated light shape, so that the entire lower boundary area of ​​the pixelated light shape becomes soft, so that the transition at the overlapping boundary with the non-pixelated light shape is more uniform and the connection is better.
