Description

Interactive light and vehicle Technical Field

[0001] The present application relates to the technical field of vehicle lighting, and in particular to an interactive light and a vehicle. Background Art

[0002] In recent years, with the large-scale launch of new energy electric vehicles, new technologies related to vehicle-machine interaction have been derived and comprehensively upgraded. In addition to the interior ambient lights, central control screen, co-pilot screen, etc. that can interact, the exterior is also a focus of improvement. For example, DLP, projection lights, and flowing signal lights can all interact according to different scenarios.

[0003] As more and more cars enter the new energy intelligent era, screens are not only placed inside the car, but can also be used outside the car to achieve human-vehicle interaction. At the same time, the observation distance is also farther. How to form a deep light effect without affecting the static effect of the screen has become a new research and development trend.

[0004] Screens with large chip center-to-center spacing values ​​for white and red light are already available on the market, enabling animation effects. However, due to the relatively large size of each chip unit, the image is not detailed enough. Therefore, to improve finesse, smaller LED chips a can be selected. However, small chips a are almost always rectangular. If the chips a are arranged horizontally (as shown in Figure 9), to achieve equal center-to-center spacing between the chips a, the vertical spacing S1' and the horizontal spacing S2' between the light-emitting edges of the chips a differ significantly, resulting in an uneven overall display on the screen and affecting the actual lighting effect. Furthermore, they are difficult to arrange within triangular or narrow corner-like areas of the screen. Summary of the Invention

[0005] According to various embodiments of the present application, an interactive light is provided.

[0006] An interactive light, comprising:

[0007] Mounting bracket;

[0008] A circuit board assembly is positioned and assembled on the mounting bracket, and a light-emitting chip array is provided on a surface of the circuit board assembly away from the mounting bracket;

[0009] a light distribution mirror, provided on a side of the circuit board assembly away from the mounting bracket and spaced apart from the circuit board assembly, wherein a display area of ​​the light distribution mirror is located in front of the light emitting direction of the light emitting chip array;

[0011] In one embodiment, the center-to-center distance between the two chip units is 2mm±0.5mm. Reducing the center-to-center distance can reduce the area of ​​the entire screen and provide more options for vehicle layout.

[0012] In one embodiment, the angle between the length direction of the chip unit and the first direction is 45 degrees, or the angle between the length direction of the chip unit and the second direction is 45 degrees.

[0014] In one embodiment, the display area of ​​the light distribution mirror is semi-transparent black.

[0015] In one embodiment, the chip unit is a white light chip or a red light chip. When a white light chip is used, it can emit white light, and when a red light chip is used, it can emit red light, thereby meeting the use requirements of the interactive screen.

[0016] In one embodiment, the light distribution mirror includes a light-proof area, the light-proof area is arranged at the periphery of the display area, and the plane contour shape of the light distribution mirror is substantially consistent with the plane contour shape of the display area.

[0017] In one embodiment, the planar outline shapes of the mounting bracket and the circuit board assembly are substantially consistent with the planar outline shapes of the display area.

[0018] In one embodiment, it further includes: a lamp body, which is arranged on a side of the mounting bracket away from the circuit board assembly, and is used to accommodate the mounting bracket and the circuit board assembly; and the light distribution lens is assembled in conjunction with the lamp body.

[0019] In one embodiment, the inner cavity shape of the lamp body is substantially consistent with the plane contour shape of the light distribution lens.

[0020] In one embodiment, the lamp body is also used to accommodate a control board; the control board is located on a side of the mounting bracket away from the circuit board assembly, and is connected to the chip unit to control the chip unit to light up and extinguish.

[0021] The present application also discloses a vehicle, comprising the interactive light described in any one of the aforementioned embodiments.

[0039] The present application will be further described below with reference to the accompanying drawings.

[0040] To facilitate understanding of the present application, a more comprehensive description of the present application will be provided below with reference to the accompanying drawings. Preferred embodiments of the present application are shown in the accompanying drawings. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Those skilled in the art will recognize that variations and modifications may be made to the various embodiments described herein without departing from the scope of the present application as defined by the appended claims. Furthermore, descriptions of well-known functions and configurations may be omitted for clarity and brevity.

[0041] It should be understood that when an element is referred to as being “fixed to” another element, it can be directly on the other element or there may also be an intervening element; when an element is considered to be “connected to” another element, it can be directly connected to the other element or there may also be an intervening element.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] The present application is based on an array of long LED chips. When the individual chips are all horizontally arranged (the length direction of the chip is consistent with the horizontal direction) and the center distance between the two chips arranged vertically is equal to the center distance between the two chips arranged horizontally, the difference between the minimum distance S1' between the light-emitting edges of the two adjacent chips in the vertical direction and the minimum distance S2' between the light-emitting edges of the two adjacent chips in the horizontal direction is large, resulting in uneven display of the entire display surface and affecting the actual lighting effect; in addition, the LED chips at the corners of the array require a large space and are difficult to arrange in the narrow area space of the triangle or similar sharp corner of the screen.

[0044] 1 to 4 , an interactive light 1 - 1 is provided in one embodiment of the present application, including:

[0045] Mounting bracket 10;

[0046] The circuit board assembly 20 is positioned and assembled on the mounting bracket 10 , and a light emitting chip array 21 is provided on a side of the circuit board assembly 20 away from the mounting bracket 10 ;

[0047] a light distribution mirror 30 , which is disposed on a side of the circuit board assembly 20 away from the mounting bracket 10 and spaced apart from the circuit board assembly 20 , wherein a display area 31 of the light distribution mirror 30 is located in front of the light emitting direction of the light emitting chip array 21 ;

[0048] The light-emitting chip array 21 includes a plurality of chip units 211 arranged at intervals along a first direction and a second direction. The angle between the length direction of the chip unit 211 (the extension direction of the long side a) and the first direction or the second direction is an acute angle, and the center distance between the two chip units 211 arranged along the first direction is substantially equal to the center distance between the two chip units 211 arranged along the second direction.

[0049] Specifically, in the present application, the first direction is the horizontal direction (the X direction in FIG. 4 ), and the second direction is the vertical direction (the Y direction in FIG. 4 ). Taking a chip package specification of 1.6 mm*0.8 mm as an example, the size of its effective light-emitting surface is 1.15 mm*0.6 mm (the packaging requirement stipulates that the area of ​​the effective light-emitting surface is generally smaller than the chip package area, and the edge of the effective light-emitting surface is referred to as the "light-emitting edge" herein). The center-to-center distance between two chip units 211 arranged in the horizontal direction and the center-to-center distance between two chip units 211 arranged in the vertical direction are both preset to be 2 mm. When the angle between the length direction of the chip unit 211 and the first direction or the second direction is acute, that is, the length direction of the chip unit 211 is acute with respect to the arrangement direction, the difference between the minimum distance S1 between the light-emitting edges of two adjacent chip units 211 in the vertical direction and the minimum distance S2 between the light-emitting edges of two adjacent chip units 211 in the horizontal direction is significantly reduced, thereby maintaining consistent light uniformity in the horizontal and vertical directions of the light-emitting chip array 21. It is worth noting that the above-mentioned basic equality means that the center distance between two chip units 211 arranged along the first direction is equal to the center distance between two chip units 211 arranged along the second direction, and there is a slight difference in the center distance between the two directions within the production error range.

[0050] In the present application, the length direction of the chip unit 211 forms an acute angle with respect to the arrangement direction, and the four packaging edges of the chip unit 211 are not attached to the edge of the light-emitting chip array area (or the display area 31 of the light distribution mirror 30), thereby increasing the redundant installation space, reducing the installation difficulty, and improving the installation success rate; and the contact mode between the light-emitting chip unit 211 at the corner and the edge of the light-emitting chip array area (or the display area 31 of the light distribution mirror 30) is changed from surface contact to point contact. In the narrow area space of the triangle or the sharp corner-like shape of the screen, the angle between the length direction of the chip unit 211 and the arrangement direction can be changed as needed, and it can be flexibly arranged in the narrow area space (such as the case where the chip unit 211 is located at the sharp corner position in the lower right corner in Figure 4).

[0051] 5, in some embodiments, the center distance between two chip units 211 is 2 mm ± 0.5 mm. Reducing the center distance can reduce the area of ​​the entire screen and provide more options for vehicle layout.

[0052] 4 to 6 , in some embodiments, the angle between the length direction of the chip unit 211 and the first direction is 45 degrees, or the angle between the length direction of the chip unit 211 and the second direction is 45 degrees.

[0053] Taking the chip specification of 1.6mm*0.8mm as an example, the center distance between two chip units 211 arranged in the transverse direction and the center distance between two chip units 211 arranged in the longitudinal direction are both preset to be 2mm. When the angle between the length direction of the chip unit 211 and the first direction is 45 degrees, or the angle between the length direction and the second direction is 45 degrees, the shortest distance S1 between the light-emitting edges of two adjacent chips in the second direction (Y direction) is basically the same as the shortest distance S2 between the light-emitting edges of two adjacent chips in the first direction (X direction). Therefore, the light-emitting uniformity of the light-emitting chip array 21 along the first direction and along the first direction can be kept completely consistent, and the light-emitting effect is better.

[0054] 1 , in some embodiments, the display area 31 of the light distribution lens 30 has at least one corner, and the light emitting chip array 21 is disposed at least corresponding to the corner of the display area 31 .

[0055] After the length direction of the chip unit 211 forms an acute angle with respect to the arrangement direction, the four edge surfaces of the chip unit 211 do not need to be attached to the folded edges of the corners of the display area 31 of the light distribution mirror 30, thereby increasing the redundant installation space and reducing the difficulty of installation; and the contact mode between the chip unit 211 at the corner and the edge of the light-emitting chip array area (or the display area 31 of the light distribution mirror 30) is changed from surface contact to point contact. In the narrow area space of the triangle or the sharp corner-like area of ​​the screen, the angle between the length direction of the chip unit 211 and the arrangement direction can be changed as needed, so that it can be flexibly arranged in the narrow area space.

[0056] During specific operations, the corners of the display area 31 may have a smaller angle. At this time, the angle between the length direction of the corner position chip unit 211 and its arrangement direction can be changed according to the actual shape of the display area 31 to adapt to the different corner shapes of the display area 31, so as to be suitable for special shapes.

[0057] In some embodiments, the display area 31 of the lens 30 is translucent black. Specifically, when the display area 31 of the lens 30 is translucent black, the internal circuit board assembly 20 and other structures are not visible from the outside when the lens is not illuminated, which improves the aesthetics of the lens. When the lens is in the interactive lighting state, light is filtered by the translucent black display area 31 before reaching the outside, providing a soft and non-glaring brightness. The lens 30 can be manufactured from PC, which is lightweight and easy to care for.

[0058] In some embodiments, the chip unit 211 is a white light chip or a red light chip. When a white light chip is used, it can emit white light, and when a red light chip is used, it can emit red light, thereby meeting the use requirements of the interactive screen.

[0059] Referring to FIG1 , in some embodiments, the lens 30 includes an opaque region 32 disposed outside the display region 31. The planar profile of the lens 30 is substantially identical to the planar profile of the display region 31. This allows full utilization of the planar space of the lens 30 and maximizes the area of ​​the display region 31.

[0060] Referring to Figure 2 , in some embodiments, the planar profiles of the mounting bracket 10 and the circuit board assembly 20 are substantially consistent with the planar profile of the display area 31. This allows the mounting bracket 10 and the circuit board assembly 20 to be positioned within the narrow triangular area between the lens 30 and the lamp body 40 to maximize space for mounting corresponding electronic components.

[0061] Referring to Figure 2 , some embodiments further include a lamp body 40, located on a side of the mounting bracket 10 away from the circuit board assembly 20, for accommodating the mounting bracket 10 and the circuit board assembly 20. Furthermore, the light distribution lens 30 is assembled with the lamp body 40. The combination of the lamp body 40 and the light distribution lens 30 allows the interactive lamp 1-1 to form a self-contained, sealed structure, ensuring safe use. Of course, in other embodiments, the interactive lamp 1-1 can be directly attached to the vehicle body, and this is not a limitation here.

[0062] Referring to Figure 2 , in some embodiments, the inner shape of the lamp body 40 is substantially identical to the planar profile of the photometric lens 30 . For example, in the figure, both the inner shape of the lamp body 40 and the planar profile of the photometric lens 30 are triangular, which precisely fits within the triangular mounting bracket 10 and circuit board assembly 20. The inner shape of the lamp body 40 is also relatively small, thus not occupying any additional space in the vehicle.

[0063] It is worth pointing out that the above-mentioned substantially consistent shapes refer to the same shapes and the situation where the two shapes are slightly different within the range of production error.

[0064] 2 , in some embodiments, the lamp body 40 is further used to accommodate a control board 50 ; the control board 50 is located on a side of the mounting bracket 10 away from the circuit board assembly 20 , and is connected to the chip unit 211 to control the chip unit 211 to light up and extinguish.

[0065] Specifically, the control board 50 can independently control the lighting and extinguishing of each chip unit 211 of the light emitting chip array 21 , so that the light emitting chip array 21 presents a desired pattern.

[0066] With reference to Figures 7-8 , a vehicle 1 is provided, including the interactive light 1-1. With the interactive light, the minimum distance between the light-emitting edges of two longitudinally adjacent chip units is substantially the same as the minimum distance between the light-emitting edges of two transversely adjacent chip units, resulting in a more uniform display across the entire display surface and a better lighting effect. Furthermore, the interactive light is easily arranged within a narrow, triangular area or sharp-angled area of ​​the screen.

[0067] It should be understood that the dimensions of all the drawings in this case do not represent the actual proportions and are merely schematic diagrams.

[0068] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
