Description

Technical Field

[0001] This disclosure relates to the technical field of vehicle lighting equipment, and in particular to a slow-moving light, a rearview mirror lighting device, and an automobile. Background Technology

[0002] To ensure driving safety in low-light conditions, most cars are equipped with running lights on their rearview mirrors. For example, Chinese patent document CN115447489A describes a rearview mirror that can provide supplemental lighting to the sides of the vehicle when the speed is below 10 km / h, thereby improving driving safety. However, due to the limited installation space on the rearview mirror, the structure of the running light assembly has to be adaptively reduced, resulting in a narrow light output range and weak luminous efficiency, ultimately leading to poor side illumination of the vehicle. Utility Model Content

[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a slow-moving light, a rearview mirror lighting device, and an automobile with a wider light emission range and more uniform light effect.

[0004] The purpose of this disclosure is achieved through the following technical solution:

[0005] A slow-moving light, comprising a light source and optical components;

[0006] The slow-moving light also includes a light-diffusing plate, and the optical component is a light-concentrating inner lens;

[0007] The light source, the inner condenser lens, and the light homogenizer are arranged sequentially; the light homogenizer has a concave-convex light-incident surface, and a light scattering gap is formed between the concave-convex light-incident surface and the light-outceasing surface of the inner condenser lens; the light emitted by the light source is focused into the light scattering gap by the inner condenser lens; the concave-convex light-incident surface is used to receive and diffuse the light so that the light is uniformly projected out by the light homogenizer.

[0008] In some embodiments, the light source includes a back plate and an LED, with the LED mounted on the back plate; the light-incident portion of the condensing inner lens covers the LED, and the edge of the light-incident portion is disposed in contact with the back plate.

[0009] In some embodiments, the slow-moving light further includes a projection lamp module, which is positioned away from the light-diffusing sheet, and the light-emitting port of the projection lamp module and the light-emitting surface of the light-diffusing sheet both face the same side.

[0010] In some embodiments, the slow-moving light further includes a beam-splitting barrier, which is provided with a first light-emitting window and a second light-emitting window; the first light-emitting window is disposed opposite to the light-emitting port of the projection lamp module, and the second light-emitting window is disposed opposite to the light-emitting surface of the light-diffusing sheet.

[0011] In some embodiments, the slow-moving light further includes a light-transmitting mask located in front of the light outlet of the projection lamp module and in front of the light-emitting surface of the light-diffusing sheet; the light-transmitting mask has a planar light-transmitting structure, which is arranged opposite to the light outlet of the projection lamp module.

[0012] In some embodiments, the outer surface of the light-transmitting mask is a flat surface, and the outer surface of the light-transmitting mask is designed to be flush with the outer surface of the rearview mirror body; or,

[0013] The outer surface of the light-transmitting mask is designed to be recessed into the outer surface of the rearview mirror body; or...

[0014] The outer surface of the light-transmitting mask is curved, and the curvature of the outer surface of the light-transmitting mask is adapted to match the curvature of the outer surface of the rearview mirror body.

[0022] An automobile includes a rearview mirror lighting device according to any of the above embodiments.

[0023] Compared with the prior art, this disclosure has at least the following advantages:

[0024] The aforementioned slow-moving light, with its sequential arrangement of the light source, inner condenser lens, and light-diffusing plate, creates a light scattering gap between the concave and convex light-incident surfaces of the light-diffusing plate and the light-exiting surface of the inner condenser lens. This allows the light emitted from the light source to be focused into this gap by the inner condenser lens. The light then refracts and diffuses on the concave and convex light-incident surfaces of the light-diffusing plate, resulting in more uniform projection. Compared to existing technologies, this slow-moving light offers a wider light emission range and more uniform light efficiency, improving lateral nighttime visibility of the vehicle.

Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0045] Please see Figure 1 and Figure 2One embodiment of a slow-moving light includes a light source 100, a converging inner lens 200, and a light-diffusing plate 300 arranged sequentially. The light-diffusing plate 300 has a concave-convex light-incident surface 310, and a light scattering gap 201 is formed between the concave-convex light-incident surface 310 and the light-emitting surface of the converging inner lens 200. Light emitted from the light source 100 is focused into the light scattering gap 201 by the converging inner lens 200. The concave-convex light-incident surface 310 is used to receive and diffuse light so that the light is uniformly projected out through the light-diffusing plate 300. The depth of the light scattering gap 201 is 0.3 mm to 2.0 mm. In some embodiments, the depth of the light scattering gap 201 is 0.3 mm, 1.0 mm, or 2.0 mm. This is only an example, and those skilled in the art can make other choices as needed.

[0046] It is understandable that, due to the sequential arrangement of the light source 100, the inner condenser lens 200, and the light diffuser 300, a light scattering gap 201 can be formed between the concave and convex light-incident surface 310 of the light diffuser 300 and the light-emitting surface of the inner condenser lens 200. This allows the light emitted from the light source 100 to be focused into the light scattering gap 201 by the focusing effect of the inner condenser lens 200. The light then refracts and diffuses on the concave and convex light-incident surface 310 of the light diffuser 300, and the diffused light is projected more evenly through the light diffuser 300. Compared with existing technologies, the aforementioned slow-moving light has a wider light emission range and more uniform light efficiency, improving the vehicle's lateral nighttime visibility.

[0047] Please see Figure 1 In some embodiments, the light source 100 includes a back plate 110 and an LED 120, with the LED 120 mounted on the back plate 110. The light-incident portion 210 of the condenser lens 200 covers the LED 120, and the edge of the light-incident portion 210 is disposed in contact with the back plate 110. It can be understood that after the light-incident portion 210 of the condenser lens 200 covers the LED 120, by displacing the edge of the light-incident portion 210 in contact with the back plate 110, the leakage of light emitted by the LED 120 from the condenser lens 200 can be reduced, thereby allowing more light emitted by the LED 120 to be received and focused by the condenser lens 200.

[0048] Please see Figure 3In this embodiment, the condensing inner lens 200 is composed of a plurality of TIR lens bodies, and the number of lamp beads 120 is at least one. Each TIR lens body is correspondingly arranged with one lamp bead 120. The light-incident portion 210 of the condensing inner lens 200 is an open structure with a diameter ranging from 4 mm to 10 mm, a depth ranging from 1 mm to 3 mm, and a thickness ranging from 5 mm to 25 mm. The edge of the open structure is attached to the back plate 110. Furthermore, the condensing inner lens 200 has textured surfaces formed inside the open structure, which can improve the uniformity of the projected light spot. In another embodiment, the condensing inner lens 200 is a freeform lens.

[0049] Please see Figure 1 and Figure 3 In some embodiments, the slow-moving light also includes a projection lamp module 400, which is positioned away from the light-diffusing sheet 300, with the light-emitting port 401 of the projection lamp module 400 and the light-emitting surface 320 of the light-diffusing sheet 300 both facing the same side. It can be understood that because the projection lamp module 400 and the light-diffusing sheet 300 are positioned away from each other and both face the same side, the projection lamp module 400 can simultaneously project patterns or logos near the bright area formed by the light projected by the light-diffusing sheet 300, thereby providing decorative lighting and enhancing the driving experience. In some embodiments, the projection lamp module 400 is a logo lamp module, capable of projecting and displaying a brand logo to strengthen brand recognition and highlight individuality.

[0050] Please see Figure 1 and Figure 2 In some embodiments, the slow-moving light also includes a beam splitter 500, which is provided with a first light-emitting window 501 and a second light-emitting window 502 separated on it; the first light-emitting window 501 is disposed opposite to the light-emitting port 401 of the projection lamp module 400, and the second light-emitting window 502 is disposed opposite to the light-emitting surface 320 of the light-diffusing sheet 300.

[0051] It is understandable that, since the light outlet 401 of the projection lamp module 400 is positioned opposite to the first light outlet window 501 on the beam splitter 500, and the light outlet surface 320 of the light homogenizer 300 is positioned opposite to the second light outlet window 502 on the beam splitter 500, the pattern or mark projected by the projection lamp module 400 can independently illuminate the outside through the first light outlet window 501, reducing stray light from the circumferential direction of the projection lamp module 400 onto the vehicle body; simultaneously, the light projected by the light homogenizer 300 can independently illuminate the outside through the second light outlet window 502, reducing stray light from the circumferential direction of the light homogenizer 300 onto the vehicle body. Furthermore, because the first light outlet window 501 and the second light outlet window 502 are separated from each other, the beam splitter 500 can reduce crosstalk between the light projected by the light homogenizer 300 and the light projected by the projection lamp module 400, thereby reducing glare.

[0052] Please see Figure 1 In this embodiment, the outer edge of the beam splitter 500 covers the outer edge of the inner condenser lens 200 and the outer edge of the projection lamp module 400. The beam splitter 500 and the inner condenser lens 200 are connected by methods not limited to adhesive bonding, ultrasonic welding, vibration welding, or snap fastening. The beam splitter 500 is opaque.

[0053] Please see Figure 1 and Figure 3 Furthermore, the slow-moving light also includes a heat sink 700, which is disposed on the back plate 110 on the side opposite to the light-diffusing sheet 300. The heat sink 700 is attached to the beam-splitting baffle 500 by screws, clips, or adhesive. Furthermore, a waterproof gasket 710 is sandwiched between the heat sink 700 and the beam-splitting baffle 500. The heat sink 700 is a finned heat sink, which can better improve the heat dissipation effect of the heat sink 700 on the back plate 110. Thermal silicone 720 is disposed between the heat sink 700 and the back plate 110, with both sides of the thermal silicone 720 abutting against the heat sink 700 and the back plate 110 respectively.

[0054] Please see Figure 1 and Figure 3In some embodiments, the slow-moving light further includes a light-transmitting mask 600, which is located in front of the light outlet 401 of the projection lamp module 400 and the light-emitting surface 320 of the light-diffusing sheet 300. The light-transmitting mask 600 has a planar light-transmitting structure 610, which is disposed opposite to the light outlet 401 of the projection lamp module 400. It can be understood that since the light-transmitting mask 600 covers the light outlet 401 of the projection lamp module 400 and the light-emitting surface 320 of the light-diffusing sheet 300, the light-transmitting mask 600 can protect the projection lamp module 400 and the light-diffusing sheet 300, while the light transmitted through the light-transmitting mask 600 will not affect the light output of the projection lamp module 400 and the light-diffusing sheet 300. Furthermore, because the area on the light-transmitting mask 600 opposite to the light outlet 401 of the projection lamp module 400 is a planar light-transmitting structure 610, the pattern or design projected by the projection lamp module 400 can be projected to the outside through the planar light-transmitting structure 610, effectively reducing the distortion caused by the pattern or design. The light-transmitting mask 600 is a light-transmitting resin mask, which is made of resin such as PC or PMMA through injection molding, giving the light-transmitting mask 600 good light transmission performance, mechanical properties, heat resistance, and weather resistance. Moreover, both the outer and inner surfaces of the light-transmitting mask 600 are mirror-finish surfaces with no optical patterns or textures.

[0055] Please see Figure 3 In this embodiment, the inner surface of the light-transmitting mask 600 is recessed to form a light-incident plane, and the outer surface of the light-transmitting mask 600 is recessed to form a light-exiting plane. The light-incident plane and the light-exiting plane are positioned correspondingly and parallel to each other to form a planar light-transmitting structure 610. It can be understood that the pattern or mark projected by the projection lamp module 400 enters the planar light-transmitting structure 610 through the light-incident plane and is then projected to the outside through the light-exiting plane, thus reducing the distortion caused by the pattern or mark. The recess depth of the light-incident plane ranges from 0.1 mm to 0.5 mm, and the diameter ranges from 5 mm to 20 mm; the recess depth of the light-exiting plane ranges from 0.1 mm to 0.5 mm, and the diameter ranges from 5 mm to 20 mm.

[0056] Please see Figure 3In some embodiments, a mounting edge 540 is formed around the outer periphery of the beam splitter 500 near the light-transmitting mask 600. An adhesive retention groove 503 is formed along the mounting edge 540 on the beam splitter 500. The edge of the light-transmitting mask 600 presses against the mounting edge 540 and covers the adhesive retention groove 503. It is understood that because the edge of the light-transmitting mask 600 presses against the mounting edge 540 and covers the adhesive retention groove 503, the adhesive in the adhesive retention groove 503 can cure the edge of the light-transmitting mask 600 and the mounting edge 540. Furthermore, the adhesive should not overflow within the adhesive retention groove 503, or welding residue can be temporarily stored within the adhesive retention groove 503 to reduce the impact of adhesive and welding residue on the optical illumination effect or the appearance of the slow-burn lamp.

[0057] Typically, due to the size limitation of the rearview mirror body 10, the projection lamp module 400 and the inner condenser lens 200 often need to be set close together. This causes the edge part of the pattern projected by the projection lamp module 400 to be projected onto the light-diffusing sheet 300 in front of the inner condenser lens 200. As a result, the light distribution of the edge part of the pattern projected by the projection lamp module 400 will be different from the light distribution of other parts of the pattern, which will cause deformation of the edge of the pattern projected by the projection lamp module 400.

[0058] Please see Figure 4 In order to reduce the deformation of the edges of the pattern projected by the projection lamp module 400, in some embodiments, the projection lamp module 400 is inclined to the inner lens 200; the light outlet 401 of the shadow lamp module is located in front of the light outlet surface 320 of the light homogenizer 300, and an angled gap 402 is formed between the side wall of the shadow lamp module and the side wall of the light homogenizer 300; a light blocking part 530 is formed on the beam splitter 500; the extension end of the light blocking part 530 is located in the angled gap 402 and extends behind the concave and convex light-incident surface 310 of the light homogenizer 300.

[0059] It is understandable that, since the projection lamp module 400 is tilted relative to the inner condenser lens 200, specifically, the end of the projection lamp module 400 that is away from the light outlet 401 of the shadow lamp module is positioned close to the light incident surface of the inner condenser lens 200. The light outlet 401 of the shadow lamp module, located in front of the light outlet surface 320 of the light homogenizer 300, is tilted away from the light homogenizer 300, thereby forming an angled gap 402 between the side wall of the shadow lamp module and the side wall of the light homogenizer 300. This causes the pattern projected by the light outlet 401 of the shadow lamp module to move away from the light homogenizer 300, thereby reducing the propagation of light from the edge of the pattern projected by the projection lamp module 400 to the light homogenizer 300. Subsequently, since the extension end of the light blocking portion 530 on the beam splitter 500 is located within the tilt gap 402, and the extension end of the light blocking portion 530 extends to the concave and convex light-incident surface 310 of the light homogenizer 300, the light rays at the edge of the pattern projected by the projection lamp module 400 will be blocked by the light blocking portion 530. That is, the light outlet 401 of the projection lamp module 400 is separated from the light homogenizer 300, thereby further reducing the propagation of the light rays at the edge of the pattern projected by the projection lamp module 400 to the light homogenizer 300. Among them, the first part of the beam splitter 500 is located between the projection lamp module 400 and the light-transmitting mask 600, and the second part of the beam splitter 500 is located between the light-emitting surface 320 of the light homogenizer 300 and the light-transmitting mask 600.

[0060] Typically, cars have rearview mirrors on both the left and right sides. To reduce wind resistance during driving, the outer surface of the rearview mirror body 10 located at different positions on the car needs to be designed with different curved structures according to the wind resistance conditions. This causes the internal space of the rearview mirror body 10 located at different positions on the car to change. In other words, the structures of the condensing inner lens 200 installed on the left and right sides of the car are different. When assembling rearview mirrors in batches, the condensing inner lens 200 and the rearview mirror body 10 located on different sides of the car are easy to be installed incorrectly, thus affecting the assembly efficiency of the rearview mirror.

[0061] To reduce the occurrence of misinstallation of the inner condenser lens 200 and the rearview mirror body 10, please refer to... Figure 4In some embodiments, a second adapter structure 520 is formed on the beam splitter 500, and the second adapter structure 520 is concave-convexly adapted to the inner condenser lens 200. It is understood that because the second adapter structure 520 is concave-convexly adapted to the inner condenser lens 200, the inner condenser lens 200 can be mounted on the beam splitter 500. In this embodiment, the inner contour of the second adapter structure 520 is adapted to the outer contour of the inner condenser lens 200. However, the contours of the inner condenser lenses 200 in the slow-moving lights on the left and right sides of the vehicle are inconsistent, so that the second adapter structure 520 formed on the beam splitter 500 in the slow-moving light on the left side of the vehicle can only be adapted to the inner condenser lens 200 on the corresponding side, thereby effectively preventing the inner condenser lens 200 from rotating or being mixed up on the left and right sides. Specifically, the second adapter structure 520 is a positioning groove structure; however, this is not limited, and those skilled in the art can make other choices.

[0062] Typically, cars have rearview mirrors on both the left and right sides. To reduce wind resistance during driving, the outer surface of the rearview mirror body 10 located at different positions on the car needs to be designed with different curved structures according to the wind resistance conditions. This causes the internal space of the rearview mirror body 10 located at different positions on the car to change. In other words, the structures of the projection lamp modules 400 installed on the left and right sides of the car are different. When assembling rearview mirrors in batches, the projection lamp modules 400 and rearview mirror bodies 10 located on different sides of the car are easy to be installed incorrectly, thus affecting the assembly efficiency of the rearview mirrors.

[0063] To reduce the occurrence of incorrect installation of the projection lamp module 400 and the rearview mirror body 10, please refer to... Figure 4 In some embodiments, a first adapter structure 510 is formed on the beam splitter 500, and the first adapter structure 510 is concave-convexly adapted to the projection lamp module 400. It can be understood that because the first adapter structure 510 is concave-convexly adapted to the projection lamp module 400, the projection lamp module 400 can be mounted on the beam splitter 500. In this embodiment, the inner contour of the first adapter structure 510 is adapted to the outer contour of the projection lamp module 400. However, the contours of the projection lamp modules 400 in the slow-moving lights on the left and right sides of the vehicle are inconsistent, so that the first adapter structure 510 formed on the beam splitter 500 in the slow-moving light on the left side of the vehicle can only adapt to the projection lamp module 400 on the corresponding side, thereby effectively preventing the projection lamp module 400 from rotating or being mixed up on the left and right sides. Specifically, the first adapter structure 510 is a positioning groove structure; however, this is not limited, and those skilled in the art can make other choices.

[0064] Typically, to reduce wind resistance during vehicle operation, the outer surface of the rearview mirror body 10 needs to be designed as a curved surface. Especially in some locations with greater curvature, the projection lamp module 400 needs to maintain a sufficiently large tilt angle relative to the inner condenser lens 200. That is, the tilt angle gap 402 formed between the side wall of the projection lamp module 400 and the side wall of the light-diffusing sheet 300 is increased. In this way, the projection lamp module 400 and the inner condenser lens 200 can be installed on the rearview mirror body 10 in locations with greater curvature. However, after the projection lamp module 400 projects a pattern, the distance between the pattern and the bright area formed by the light-diffusing sheet 300 will increase, and the brightness compensation of the bright area for the pattern will be less, resulting in a decrease in the brightness of the pattern.

[0065] Please see Figure 4 and Figure 5 In order to reduce the gap between the pattern and the bright area formed by the projection through the light diffuser 300, in one embodiment, the light-transmitting mask 600 is provided with an installation channel 601 at a position corresponding to the first light-emitting window 501; the planar light-transmitting structure 610 has a planar light-incident portion 6110 and a planar light-emitting portion 6120 that are parallel to each other, the planar light-transmitting structure 610 is installed in the installation channel 601, and the arc-shaped outer peripheral portion 6130 of the planar light-transmitting structure 610 slides against the arc-shaped inner peripheral wall of the installation channel 601; the light-emitting port 401 of the projection lamp module 400 passes through the first light-emitting window 501 and is close to the planar light-incident portion 6110 of the planar light-transmitting structure 610; the arc-shaped outer peripheral portion 6130 of the planar light-transmitting structure 610 slides relative to the arc-shaped inner peripheral wall of the installation channel 601, so that the planar light-incident portion 6110 swings toward the side of the condensing inner lens 200.

[0066] It is understandable that, since the arc-shaped outer periphery 6130 of the planar light-transmitting structure 610 slides against the arc-shaped inner peripheral wall of the mounting channel 601, when the gap between the pattern projected by the projection lamp module 400 and the bright area formed by the projection through the light-diffusing sheet 300 is too large, the arc-shaped outer periphery 6130 of the planar light-transmitting structure 610 can be adjusted to slide relative to the arc-shaped inner peripheral wall of the mounting channel 601, so that the planar light-incident part 6110 swings towards one side of the condensing inner lens 200, thereby allowing the pattern projected by the projection lamp module 400 to be projected in front of the condensing inner lens 200 through the planar light-transmitting structure 610, thereby reducing the gap between the pattern projected by the projection lamp module 400 and the bright area formed by the projection through the light-diffusing sheet 300.

[0067] Typically, because cars are prone to bumps during driving, the planar light-transmitting structure 610 is prone to shaking within the installation channel 601, which causes the pattern projected through the planar light-transmitting structure 610 to shake on the lane, thereby affecting the safe driving of other vehicles on the lane.

[0068] Please see Figure 5 and Figure 6 To reduce the swaying of the planar light-transmitting structure 610 within the mounting channel 601, in one embodiment, a stop protrusion 6131 is formed on the arc-shaped outer periphery 6130 of the planar light-transmitting structure 610. A guide groove 6011 and a plurality of hovering slots 6012 are provided on the arc-shaped inner peripheral wall of the mounting channel 601. The stop protrusion 6131 is slidably disposed within the guide groove 6011, and the plurality of hovering slots 6012 are spaced apart along the sliding path of the stop protrusion 6131. ​​Each hovering slot 6012 is connected to the guide groove 6011. The hovering slots 6012 are used to hold the stop protrusion 6131 so that the planar light-transmitting structure 610 maintains a fixed sway angle.

[0069] It is understandable that, since the stop protrusion 6131 is slidably disposed in the guide groove 6011, when it is necessary to adjust the planar light-incident part 6110 to swing toward the side of the condensing inner lens 200, the stop protrusion 6131 can be guided to slide through the guide groove 6011, so that the planar light-transmitting structure 610 swings stably in the mounting channel 601. After the planar light-incident part 6110 swings to the side of the condensing inner lens 200 in place, the planar light-transmitting structure 610 can be twisted to make the stop protrusion 6131 enter and be locked in the suspension slot 6012, thereby making the planar light-transmitting structure 610 maintain a fixed swing angle in the mounting channel 601.

[0070] Please see Figure 5 Furthermore, in order to increase the stability of the sway angle of the planar light-transmitting structure 610 within the mounting channel 601, in one embodiment, the number of stop protrusions 6131 is two, the two stop protrusions 6131 are coaxially arranged, and the axis O of the two stop protrusions 6131 is inclined toward the direction of the condensing inner lens 200. It is understandable that, since the two stop protrusions 6131 are coaxially arranged and their axes are inclined toward the condenser inner lens 200, when it is necessary to adjust the planar light-incident part 6110 to swing toward one side of the condenser inner lens 200, the two stop protrusions 6131 can swing synchronously in the corresponding guide groove 6011. After the planar light-incident part 6110 swings to one side of the condenser inner lens 200, the planar light-transmitting structure 610 can be twisted so that the two stop protrusions 6131 enter and lock into the corresponding hovering slot 6012 synchronously. Finally, the two stop protrusions 6131 can make the swing angle of the planar light-transmitting structure 610 in the installation channel 601 more stable.

[0071] Please see Figure 4Furthermore, the light outlet 401 of the projection lamp module 400 and the light-emitting surface 320 of the light-diffusing sheet 300 are on the same plane or different planes. The back plate 110 is a circuit board, and at least one LED 120 on the circuit board corresponds to the position of the light inlet of the projection lamp module 400. The light inlet of the projection lamp module 400 is attached to the back plate 110, which can reduce the light leakage of the LED 120. The back plate 110 can be a single piece or two separate pieces to flexibly meet different target ground light spots and the space requirements of the rearview mirror body 10.

[0072] In some embodiments, the outer surface of the light-transmitting mask 600 is flat and is flush with the outer surface of the rearview mirror body 10. It is understood that by making the outer surface of the light-transmitting mask 600 flush with the outer surface of the rearview mirror body 10, the appearance of the outer surface of the light-transmitting mask 600 and the outer surface of the rearview mirror body 10 can be made uniform, thereby reducing wind resistance when the vehicle is in motion.

[0073] Please see Figure 1 In this embodiment, the outer surface of the light-transmitting mask 600 is recessed below the outer surface of the rearview mirror body 10. It can be understood that because the outer surface of the light-transmitting mask 600 is recessed below the outer surface of the rearview mirror body 10, an observer will not be able to directly see the outer surface of the light-transmitting mask 600 within a specified area. This specified area conforms to the requirements of the national standard GB5920-2024.

[0074] In some embodiments, the outer surface of the light-transmitting mask 600 is curved, and the curvature of the outer surface of the light-transmitting mask 600 is adapted to the curvature of the surface of the rearview mirror body 10. It can be understood that because the outer surface of the light-transmitting mask 600 is curved, and the curvature of the outer surface of the light-transmitting mask 600 is adapted to the curvature of the surface of the rearview mirror body 10, the rearview mirror body 10 forms a complete curved surface on its outer surface, which can better adapt to the airflow and further reduce wind resistance when the vehicle is driving. The outer surface of the light-transmitting mask 600 is offset from the light source element 100 in a direction ranging from 0.1 mm to 10 mm to obtain the curved surface.

[0075] Please see Figure 2 In this embodiment, the vertical cross-section of the concave-convex light-incident surface 310 is wavy. It can be understood that because the vertical cross-section of the concave-convex light-incident surface 310 is wavy, the light within the light scattering gap 201 can be refracted and diffused through the concave-convex light-incident surface 310.

[0076] In some embodiments, the cross-section of the uneven light-incident surface 310 is serrated. It can be understood that because the vertical cross-section of the uneven light-incident surface 310 is serrated, light within the light scattering gap 201 can be refracted and diffused through the uneven light-incident surface 310.

[0077] Please see Figure 1 In this embodiment, the uneven light-receiving surface 310 is provided with stripes. It can be understood that because the uneven light-receiving surface 310 is provided with stripes, the light received by the uneven light-receiving surface 310 can produce a directional light distribution, which is suitable for emphasizing the directionality and layering of the light. The height of the stripes ranges from 0.3 mm to 2 mm.

[0078] In some embodiments, the uneven light-receiving surface 310 is provided with a grid pattern. It can be understood that because the uneven light-receiving surface 310 has a grid pattern, the light received by the uneven light-receiving surface 310 can be distributed over a larger area with a more uniform light spot, suitable for the needs of large-area lighting. The height of the grid pattern ranges from 0.3 mm to 2 mm.

[0079] In some embodiments, the uneven light-receiving surface 310 is provided with a diamond-shaped pattern. It is understood that because the uneven light-receiving surface 310 is provided with a diamond-shaped pattern, the light received by the uneven light-receiving surface 310 can produce a light spot with a specific geometric shape, suitable for lighting scenarios requiring specific geometric effects. The height of the diamond-shaped pattern ranges from 0.3 mm to 2 mm.

[0080] In some embodiments, the uneven light-receiving surface 310 is provided with circular patterns. It is understood that the circular patterns on the uneven light-receiving surface 310 result in a softer light distribution received by the surface. The height of the circular patterns ranges from 0.3 mm to 2 mm.

[0081] Please see Figures 1 to 3 This disclosure also provides a rearview mirror lighting device, including a rearview mirror body 10 and a slow-moving light of any of the above embodiments; the slow-moving light is mounted on the rearview mirror body 10. It can be understood that by applying the slow-moving light of this disclosure to the rearview mirror lighting device, the light emitted by the light source 100 is focused into the light scattering gap 201 by the focusing effect of the inner focusing lens 200. The light is then refracted and diffused on the concave-convex light-incident surface 310 of the light-diffusing plate 300, and the diffused light can be projected more evenly through the light-diffusing plate 300. For example, when camping outdoors, the user can use the slow-moving light to provide ground illumination.

[0082] Please see Figures 1 to 3 This disclosure also provides an automobile including a rearview mirror lighting device according to any of the above embodiments. It is understood that by applying the rearview mirror lighting device of this disclosure to an automobile, the automobile is not limited to components such as wheels, steering wheel, and powertrain. The automobile can be a gasoline-powered vehicle, an electric vehicle, or a hybrid vehicle, and is not limited to sedans, SUVs, MPVs, or other types of vehicles. The aforementioned slow-moving lights have a wider light emission range and more uniform light efficiency, which can improve the vehicle's lateral nighttime visibility.

[0083] Compared with the prior art, this disclosure has at least the following advantages:

[0084] In the aforementioned slow-moving light, the light source 100, the inner condenser lens 200, and the light-diffusing plate 300 are arranged sequentially, creating a light scattering gap 201 between the concave and convex light-incident surface 310 of the light-diffusing plate 300 and the light-emitting surface of the inner condenser lens 200. This allows the light emitted from the light source 100 to be focused into the light scattering gap 201 by the focusing effect of the inner condenser lens 200. The light then refracts and diffuses on the concave and convex light-incident surface 310 of the light-diffusing plate 300, and the diffused light is projected more evenly through the light-diffusing plate 300. Compared to existing technologies, the aforementioned slow-moving light has a wider light emission range and more uniform light efficiency, improving the vehicle's lateral nighttime visibility.

[0085] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
