Description

Multi-pixel far-light system, car lamp and car

Technical Field

The present invention relates to a vehicle lamp, and more particularly, to a multi-pixel remote light system. In addition, the invention also relates to a vehicle lamp and a vehicle.

Background

The intelligent system of the vehicle is more and more popular, the most applied at present is the multi-pixel intelligent high beam function, and the intelligent high beam function can guarantee the driving vision of the driver to the maximum extent and improve the safety and comfort of the vehicle driving on the premise of preventing other vehicles from dazzling. There are currently mainly two forms to achieve a multi-pixel high beam that can be switched off: reflective and transmissive. Compared with a reflective system, the projection system needs to add a lens and other projection elements, and the cost is much higher than that of the reflective system; the reflective system has a certain advantage in cost because it is composed of a mirror.

In addition, with the continuous development of the multi-pixel intelligent high beam technology, a multi-pixel intelligent high beam system needs to meet new requirements, the width of a single pixel of the multi-pixel intelligent high beam can be set independently according to the actual situation of a vehicle driving road, a dark zone with high resolution needs to be formed in the area right in front of a lane, the width of the single pixel is narrow, so that the width of the formed dark zone is controlled more accurately and is matched with the width of the area where the vehicle or the pedestrian is located, and the vision of a driver of the vehicle can be ensured while the dazzling of the opposite side is prevented; and the number of vehicles or pedestrians in the two side areas in front of the lane is less, a dark area with high resolution is not required to be formed, the width of a single pixel can be widened, and the width of a plurality of pixels of the high beam shape forms a gradual change trend from wide to narrow from outside to inside.

One structure of the current reflective multi-pixel far-light system is composed of a multi-chip light source (with chips arranged laterally) and a reflector. After light emitted from the light emitting source is reflected by the reflector, a high beam shape with a certain width corresponding to the size of the light emitting chip is formed, wherein the number of pixels is determined by the number of the chips, the width of a single pixel is determined by the single light emitting chip and the reflector together, the width range of the single pixel is very small, and the width difference of different pixels is caused to be very large. This system does not meet the above requirements for the case where different pixels with widely different widths are required.

The chinese patent application No. CN107420825A, whose application date is 27/9/2017, discloses another structure of a reflective multi-pixel far-light system, which is composed of a reflector and a plurality of LED light sources, wherein the plurality of LED light sources share one reflector, and a focus of the reflector is necessarily disposed on the LED light source at the middle position, but if pixels corresponding to the LED light sources one by one are to be formed, it is necessary that other LED light sources are as close as possible to the focus of the reflector, and all the LED light sources correspond to one reflector, so that the widths of the pixels formed by the LED light sources are substantially the same, and the width of each pixel cannot be changed individually, and thus the requirement of multi-pixel combination with a specific width cannot be satisfied.

Detailed Description

In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "front", and the like, indicate orientations or positional relationships for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Wherein, the left direction is the direction of the left hand when the user looks at the front of the vehicle in the vehicle, and the right direction is the direction of the right hand when the user looks at the front of the vehicle in the vehicle; "Upper", "lower", "front", "back" are based on the orientation shown in FIG. 2.

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

The invention provides a multi-pixel high beam system, which comprises a plurality of light-emitting sources 1, as well as a light-condensing element and at least one reflecting element which are matched with the light-emitting sources 1, wherein the light-condensing element is provided with a plurality of light-condensing units which are arranged in parallel and have set widths, each light-emitting source 1 is in one-to-one correspondence with each light-condensing unit respectively, so that light rays emitted by each light-emitting source 1 can be condensed by the light-condensing elements and reflected by the reflecting elements to form a plurality of light spots, the plurality of light spots are sequentially arranged to form a light shape with a plurality of pixels, and the width of each light spot corresponds to the set width of each light-condensing unit.

It should be noted that, as shown in the light shape diagrams of fig. 13 and 14, each lattice of the high beam shape a represents a pixel, the high beam shape a is formed by sequentially arranging a plurality of light spots along the left and right direction, if the light spots are just connected with each other, the width of the pixel is the same as the width of the corresponding light spot, however, in this case, there is a clear bright and dark boundary between the pixels, so that the uniformity of the high beam shape is poor, therefore, in order to make the connection transition between the pixels uniform, there is a partial overlap between the light spots, and at this time, the width of the light spot should be larger than the width of the corresponding pixel. Since the width of the light spot corresponds to the width of the corresponding light condensing unit, in order to realize a light shape having high resolution in the vicinity area immediately in front of the vehicle and low resolution in both side areas in front of the vehicle as shown in fig. 13 and 14, light spots having different widths can be obtained by setting the width of each light condensing unit to form a multi-pixel high beam shape having a plurality of pixels of a specific width. Here, the area where the light shape of the area in the vicinity of the vehicle front is projected on the light distribution screen is the light shape center area (the area where the intersection of the horizontal 0-degree line and the vertical 0-degree line is located) in the light shape schematic diagrams shown in fig. 13 and 14, and the areas where the light shapes of the areas on both sides of the vehicle front are projected on the light distribution screen are the light shape outer areas in the light shape schematic diagrams shown in fig. 13 and 14.

The light condensing element of the invention forms a plurality of light condensing units which are arranged in parallel and have set width, so that light rays emitted by each light emitting source 1 can be collected and condensed by the light condensing element and reflected by the reflecting element to form a high beam shape with a plurality of pixels with specific width, and light spots with width corresponding to the width of each light condensing unit can be formed by setting the width of each light condensing unit of the light condensing element, thereby forming a plurality of pixels with specific width, so that the width of each pixel can be adjusted, thereby the width of a single pixel can be set independently according to the actual condition on the driving road of a vehicle, and the requirement of multi-pixel intelligent illumination can be met.

As a specific embodiment, as shown in fig. 1 to 3, the light-gathering element is a multi-cavity reflector 2, the multi-cavity reflector 2 includes a plurality of reflective cavities 21 arranged in parallel and having a set width, and the reflective cavities 21 are light-gathering units on the light-gathering element. The number of the reflecting elements is two, the reflecting elements are respectively a first reflector 4 and a second reflector 3, the first reflector 4 is arranged right in front of the multi-cavity reflector 2, the second reflector 3 is arranged below the multi-cavity reflector 2, and light rays emitted by the light emitting sources 1 are collected and converged by the multi-cavity reflector 2 and are reflected by the first reflector 4 and the second reflector 3 in sequence to form a high beam shape with a plurality of pixels. By arranging the first reflector 4 and the second reflector 3, the incident and emergent directions of the light rays emitted by the light-emitting source 1 can be better adjusted through multi-stage reflection, so that the expected high beam shape is better formed, and the structure of the invention is more compact.

Specifically, as shown in fig. 6 to 8 and 10 to 12, the reflecting surface of each reflecting cavity 21 is a paraboloid, each light-emitting source 1 is correspondingly arranged at the focal point of each reflecting cavity 21, and by arranging the paraboloid reflecting surface, most of light emitted by the light-emitting sources 1 can be collected and converged and reflected to the first reflector 4, so that the light efficiency can be improved. Of course, the reflecting surface of each reflecting cavity 21 may also be a curved surface reflecting surface such as an arc surface, an ellipsoid surface, or the like, as long as it can collect, converge, and reflect the light emitted by the light source 1 to the first reflector 4, which also belongs to the protection scope of the present invention. Since the reflective cavities 21 are arranged in parallel, in order to prevent stray light from being generated between adjacent reflective cavities 21 due to a cross-talk phenomenon, which affects the formation of a desired light shape, it is preferable that a spacer 22 is provided between adjacent reflective cavities 21 to separate them from each other.

Wherein, the multi-cavity reflector 2 includes 8 reflective cavities 21, the width of each reflective cavity 21 can be adjusted according to the actual light distribution and the width of the required light spot, because when actually applied to the vehicle lamp, it is required to form a high beam shape with wide pixel width (low resolution) in the outer region of the light shape and narrow pixel width (high resolution) in the central region of the light shape, when applied to the left vehicle lamp, the width of each reflective cavity 21 is set to correspond to the width of each pixel from left to right in fig. 13, a in fig. 13 indicates a high beam shape with 8 pixels, b indicates a low beam shape, c indicates a low beam cutoff line, the width of 8 pixels in fig. 13 decreases gradually from left (outer region of the light shape) to right (central region of the light shape), theoretically, the width of each reflective cavity 21 also tends to decrease gradually from right to left, however, for uniform connection between pixels, to partially overlap each light spot, the width of each reflective cavity 21 as shown in fig. 11 may be set according to the width of the light spot that needs to be obtained, and does not necessarily have a gradual change trend in size, as long as each light spot is finally arranged to obtain a light shape in which the pixel width gradually decreases from the outer region of the light shape to the central region of the light shape; when the width of each reflective cavity 21 is set to be corresponding to the width of each pixel in fig. 14 from left to right, a in fig. 14 indicates a high beam shape with 8 pixels, b indicates a low beam shape, c indicates a low beam cutoff line, and the width of 8 pixels in fig. 14 increases gradually from left (central region of the light shape) to right (outer region of the light shape), so that the width of each reflective cavity 21 theoretically increases gradually from right to left. Thus, the emission light shapes of the left and right lamps are superimposed to form a high beam shape having a wide pixel width (low resolution) in the outer region of the light shape and a narrow pixel width (high resolution) in the center region of the light shape.

Of course, the width setting of the plurality of reflective cavities 21 of the multi-cavity reflector 2 may have different implementations, and both may form a high beam shape having a wide pixel width (low resolution) in the outer region and a narrow pixel width (high resolution) in the central region of the beam shape after the light shapes emitted from the left and right lamps are superimposed. Referring to fig. 15 to 17, fig. 15 is a schematic view showing a front view structure of a multi-cavity reflector 2 when applied to a left vehicle lamp (i.e. a view structure when the multi-cavity reflector 2 is mounted on the left vehicle lamp and viewed from the front of the vehicle to the interior of the vehicle), the widths of a first reflective cavity 21, a second reflective cavity 21, a third reflective cavity 21 and a fourth reflective cavity 21 counted from the left side are not greatly different, the width of the fifth reflective cavity 21 is greater than that of the fourth reflective cavity 21, the width of the sixth reflective cavity 21 is greater than that of the fifth reflective cavity 21, the overall emergent light shape formed on a light distribution screen is specifically as shown in fig. 18, fig. 19 to 24 show corresponding light spots formed after light rays emitted by each light-emitting light source 1 are reflected by the corresponding reflective cavities 21 and reflected by a reflective element, and it can be seen from the figures that each light spot is partially overlapped after being sequentially arranged, and light spots formed by the first reflective cavities 21, The width difference between the light spot formed correspondingly by the second reflective cavity 21, the light spot formed correspondingly by the third reflective cavity 21 and the light spot formed correspondingly by the fourth reflective cavity 21 is not large, the width of the light spot formed correspondingly by the fifth reflective cavity 21 is larger than that of the light spot formed correspondingly by the fourth reflective cavity 21, and the width of the light spot formed correspondingly by the sixth reflective cavity 21 is larger than that of the light spot formed correspondingly by the fifth reflective cavity 21, and the light spots correspond to the width of the reflective cavities 21 one by one. As shown in fig. 25, turning off the light shape schematic diagram formed by the light emitting source 1 corresponding to the second, fourth, and sixth reflective cavities 21, it can be seen that the width of the dark space between the light spot formed corresponding to the third reflective cavity 21 and the light spot formed corresponding to the fifth reflective cavity 21 is the width of the pixel corresponding to the fourth reflective cavity 21, which is greater than the width of the pixel corresponding to the second reflective cavity 21 located on the right side thereof (i.e., the width of the dark space between the light spot formed corresponding to the first reflective cavity 21 and the light spot formed corresponding to the third reflective cavity 21); as shown in fig. 26, similarly, the pixel width corresponding to the fifth reflective cavity 21 is larger than the pixel width corresponding to the third reflective cavity 21 located at the right side thereof; with reference to fig. 25 and fig. 26, it can be seen that the pixel width corresponding to the fifth reflective cavity 21 is greater than the pixel width corresponding to the fourth reflective cavity 21 located on the right side thereof, the pixel width corresponding to the fourth reflective cavity 21 is greater than the pixel width corresponding to the third reflective cavity 21 located on the right side thereof, and the pixel width corresponding to the third reflective cavity 21 is as much as the pixel width corresponding to the second reflective cavity 21 located on the right side thereof, which conforms to the characteristic that the pixel width of the outgoing light shape of the left vehicle light gradually decreases from the light shape outer region to the light shape central region. Fig. 16 is a schematic front view of the multi-cavity reflector 2 applied to a right lamp, in which the variation law of the width of the reflective cavity 21 is opposite to the variation law of the reflective cavity 21 shown in fig. 15, a right lamp outgoing light shape is formed on the light distribution screen, the pixel width of the right lamp outgoing light shape gradually decreases from the outer region of the light shape to the central region of the light shape, and the left lamp outgoing light shape and the right lamp outgoing light shape are superimposed to form a high beam light shape having a wide pixel width at two sides and a narrow pixel width in the middle. Fig. 17 is a schematic view showing another front view structure of the multi-cavity reflector 2 applied to the left lamp and the right lamp, the multi-cavity reflector 2 applied to the left lamp and the right lamp has the same structure, the width of the reflecting cavity 21 is gradually reduced from two sides to the middle, and the high beam shape with wide pixel width at two sides and narrow pixel width at the middle can be formed after the emergent beam shapes of the left lamp and the right lamp are overlapped.

Preferably, as shown in fig. 25 to 27, each of the light-emitting light sources 1 is a single-chip light-emitting light source and can be independently turned on, so that in practical application, by controlling on/off of each light-emitting light source, brightness of a corresponding pixel can be realized, and thus adaptive high beam illumination can be flexibly realized.

In the above embodiment, specifically, the reflecting surface of the first reflector 4 is a flat surface, and the first reflector 4 is disposed in front of the multi-cavity reflector 2 in an inclined manner from top to bottom in a direction away from the light-emitting source 1, so that the light rays collected and reflected by the multi-cavity reflector 2 can be incident on the reflecting surface of the second reflector 3 after being reflected by the first reflector 4. By setting the reflecting surface of the first reflector 4 to be a plane, the outgoing direction of the light can be better controlled, and it is ensured that more light is incident on the reflecting surface of the second reflector 3. Of course, the reflecting surface of the first reflector 4 may be other curved surfaces capable of reflecting light.

Specifically, as shown in fig. 9, the second reflector 3 includes two reflecting surfaces with a step difference, that is, the second reflector 3 is formed by splicing two reflecting surfaces with a step difference, and the two reflecting surfaces are preferably parabolic reflecting surfaces. Two plane of reflection correspond a focus respectively, compare and adopt a plane of reflection that has a focus, the light shape effect can be better, simultaneously, if the plane of reflection of second reflector 3 is a holistic plane of reflection, the width of plane of reflection on left right direction need be accomplished very greatly, just can guarantee to obtain the light shape of needs, and separate the plane of reflection for two, can design the adjustment respectively to two planes of reflection to make the plane of reflection of second reflector 3 need not accomplish very greatly, just can form anticipated light shape. In addition, since the second reflector 3 has two reflecting surfaces, in order to prevent light leakage and affect light efficiency, it is preferable that a partition plate 31 is provided between the two reflecting surfaces.

Preferably, the light source 1 is provided with a light shielding portion 8 in front of it for shielding part of direct light incident on the multi-cavity reflector 2, and the light shielding portion 8 is located above the multi-cavity reflector 2. If the part of the direct light is reflected to the front of the vehicle by the multi-cavity reflector 2 and the reflecting element in sequence, pedestrians or oncoming drivers of the vehicle can dazzle the vehicle, and traffic accidents are easy to happen; the light shielding portion 8 can also block scattered or diffused light from the light emitting light source 1 from being projected toward a specific region of the multi-cavity reflector 2, avoiding unwanted light and glare that occurs outside of the desired resulting light pattern. As shown in fig. 7, the light shielding portion 8 has a plate-like structure, and the light shielding portion 8 is preferably integrally formed with the heat sink 5, so that it is not necessary to add a mounting structure, and the structure is more compact.

As another specific embodiment, as shown in fig. 28, the light-condensing element is a multi-cavity reflector 2, the multi-cavity reflector 2 includes a plurality of reflecting cavities 21 arranged in parallel and having a set width, the number of the reflecting elements is two, and the reflecting cavities are respectively a first reflector 4 and a second reflector 3, the first reflector 4 is arranged right in front of the multi-cavity reflector 2, the second reflector 3 is located above the multi-cavity reflector 2, and light rays emitted by each of the light-emitting light sources 1 are collected and converged by the multi-cavity reflector 2 and then are sequentially reflected by the first reflector 4 and the second reflector 3 to form a high beam shape having a plurality of pixels.

Since the second reflector 3 is located above the multi-cavity reflector 2, in order to enable the light rays converged and reflected by the multi-cavity reflector 2 to be reflected by the first reflector 4 and then enter the reflecting surface of the second reflector 3, the first reflector 4 is obliquely arranged right in front of the multi-cavity reflector 2 from top to bottom in a direction close to the light emitting source 1.

As another specific embodiment, as shown in fig. 29 to 32, the light-gathering element is a light-gathering device 9, the light-gathering device 9 includes a plurality of collimation units 91 arranged in parallel, light-entering ends of the collimation units 91 are separated from each other, the light-entering ends of the collimation units 91 are in one-to-one correspondence with the light-emitting sources 1, light-emitting ends of the collimation units 91 are connected to each other to form a light-emitting surface, and end surfaces of the light-emitting ends of the collimation units 91 have a set width, respectively, so as to form the light-gathering unit. The number of the reflecting elements is two, the reflecting elements are respectively a first reflector 4 and a second reflector 3, the first reflector 4 is arranged right in front of the condenser 9, the second reflector 3 is arranged below the condenser 9, of course, the second reflector 3 can also be arranged above the condenser 9, and light rays emitted by the light emitting sources 1 are converged by the condenser 9 and then are reflected by the first reflector 4 and the second reflector 3 in sequence to form a high beam shape with a plurality of pixels.

As still another embodiment, as shown in fig. 33, the number of the reflecting elements is one, and the reflecting elements are second reflectors 3, and the second reflectors 3 are disposed below the multi-cavity reflector 2. Forming a high beam shape with a plurality of pixels of a specific width can also be achieved by providing one reflective element.
