Technical Field
[0001] The present disclosure relates to the technical field of vehicle-mounted lighting equipment, and in particular to a slow-running light, a rearview mirror lighting device, and a vehicle. Background Art
[0002] To ensure driving safety in dimly lit environments, most cars have slow-running lights installed on their rearview mirrors. For example, Chinese patent document CN115447489A provides a rearview mirror that, when the vehicle speed is below 10 km / h, uses a slow-running light assembly to provide supplemental lighting to the side of the vehicle body, thereby improving driving safety. However, due to the limited installation space on the rearview mirror, the structure of the slow-running light assembly must be adaptably reduced, resulting in a narrow light output range and weak light efficiency, ultimately leading to poor lateral lighting effects from the slow-running light assembly. Summary of the Invention
[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a slow-moving lamp, a rearview mirror lighting device and a vehicle with a wider light output range and more uniform light effect.

[0005] A slow-running light, comprising a light source component and an optical component;
[0006] The slow-moving light also includes a light-homogenizing sheet, and the optical component is a focusing inner lens;

[0011] In some embodiments, the slow-running light further includes a light-transmitting mask, which is located in front of the light outlet of the projection lamp module and in front of the light outlet surface of the light-distributing sheet; the light-transmitting mask is provided with 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 used to be flush with the outer surface of the rearview mirror body; or,

[0041] To facilitate understanding of the present disclosure, a more comprehensive description of the present disclosure will be provided below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present disclosure. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure.
[0042] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.
[0043] 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 disclosure pertains. The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0044] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:
[0045] See also Figure 1 and Figure 2In one embodiment, a slow-running light includes a light source 100, a focusing inner lens 200, and a light diffuser 300, which are sequentially arranged. The light diffuser 300 has a concave-convex light entrance surface 310, forming a light-scattering gap 201 between the concave-convex light entrance surface 310 and the light-emitting surface of the focusing inner lens 200. Light emitted by the light source 100 is converged within the light-scattering gap 201 by the focusing inner lens 200. The concave-convex light entrance surface 310 is used to receive and diffuse light so that the light is evenly projected through the light diffuser 300. The depth of the light-scattering gap 201 ranges from 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 for illustrative purposes only, and those skilled in the art may make other selections as needed.
[0046] It can be understood that because the light source 100, the focusing inner lens 200, and the light homogenizer 300 are arranged in sequence, a light-scattering gap 201 is formed between the concave-convex light-entry surface 310 of the light homogenizer 300 and the light-emitting surface of the focusing inner lens 200. As a result, the light emitted by the light source 100 is concentrated in the light-scattering gap 201 through the focusing effect of the focusing inner lens 200. The light is then refracted and diffused on the concave-convex light-entry surface 310 of the light homogenizer 300. The diffused light can be projected more evenly through the light homogenizer 300. Compared with the prior art, the above-mentioned slow-running light has a wider light output range and more uniform light effect, which can improve the night vision of the side of the vehicle body.
[0047] See also Figure 1 In some embodiments, the light source unit 100 includes a back plate 110 and a lamp bead 120, wherein the lamp bead 120 is mounted on the back plate 110; the light entrance portion 210 of the focusing inner lens 200 covers the lamp bead 120, and the edge of the light entrance portion 210 is disposed in contact with the back plate 110. It is understood that after the light entrance portion 210 of the focusing inner lens 200 covers the lamp bead 120, by making the edge of the light entrance portion 210 in contact with the back plate 110, it is possible to reduce the leakage of light emitted by the lamp bead 120 from the focusing inner lens 200, thereby allowing more light emitted by the lamp bead 120 to be received and concentrated by the focusing inner lens 200.
[0048] See also Figure 3In this embodiment, the concentrating inner lens 200 is composed of several TIR lenses, with at least one lamp bead 120, each TIR lens corresponding to one lamp bead 120. The light entrance portion 210 of the concentrating inner lens 200 is an opening 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 opening structure is affixed to the back panel 110. Furthermore, the concentrating inner lens 200 has a sunburst pattern formed within the opening structure to improve the uniformity of the projected light spot. In another embodiment, the concentrating inner lens 200 is a free-form surface lens.
[0049] See also Figure 1 and Figure 3 In some embodiments, the slow-running light also includes a projection lamp module 400, and the projection lamp module 400 and the light-distributing plate 300 are arranged in a avoidance manner, and the light outlet 401 of the projection lamp module 400 and the light-distributing surface 320 of the light-distributing plate 300 are both facing the same side. It can be understood that since the projection lamp module 400 and the light-distributing plate 300 are both arranged in a avoidance manner and facing the same side, the projection lamp module 400 can simultaneously project a pattern or logo near the bright area formed by the projection of the light-distributing plate 300, thereby providing decorative functional lighting and enhancing the car-using experience. In some embodiments, the projection lamp module 400 is a logo lamp module that can project and display a brand logo to enhance brand recognition and highlight individuality.
[0050] See also Figure 1 and Figure 2 In some embodiments, the slow-running light further includes a light-splitting barrier 500 , on which a first light-exiting window 501 and a second light-exiting window 502 are separately provided; the first light-exiting window 501 is arranged opposite to the light-exiting port 401 of the projection lamp module 400 , and the second light-exiting window 502 is arranged opposite to the light-exiting surface 320 of the light-distributing sheet 300 .
[0051] It can be understood that because the light outlet 401 of the projection lamp module 400 is positioned opposite to the first light outlet window 501 provided on the light-splitting barrier 500, and the light outlet surface 320 of the light-dispersing plate 300 is positioned opposite to the second light outlet window 502 provided on the light-splitting barrier 500, the pattern or logo projected by the projection lamp module 400 can independently pass through the first light outlet window 501 to the outside world, thereby reducing the amount of stray light generated by the circumferential direction of the projection lamp module 400 on the vehicle body. At the same time, the light projected by the light-dispersing plate 300 can independently pass through the second light outlet window 502 to the outside world, thereby reducing the amount of stray light generated by the circumferential direction of the light-dispersing plate 300 on the vehicle body. Furthermore, because the first light outlet window 501 and the second light outlet window 502 are separated from each other, the light-splitting barrier 500 can reduce the crosstalk between the light projected by the light-dispersing plate 300 and the light projected by the projection lamp module 400, thereby reducing the generation of glare.
[0052] See also Figure 1 In this embodiment, the outer edge of the beam splitter barrier 500 covers the outer edge of the inner focusing lens 200 and the outer edge of the projection lamp module 400. The beam splitter barrier 500 and the inner focusing lens 200 are fastened together using various methods, including gluing, ultrasonic welding, vibration welding, and snap fastening. The beam splitter barrier 500 is opaque.
[0053] See also Figure 1 and Figure 3 Furthermore, the slow-running light also includes a radiator 700, which is disposed on the side of the backplate 110 facing away from the light diffuser 300. The radiator 700 is bonded to the light-splitting barrier 500 via screws, clips, or glue. Furthermore, a waterproof gasket 710 is sandwiched between the radiator 700 and the light-splitting barrier 500. The radiator 700 is a fin-type radiator, which can better improve the heat dissipation effect of the radiator 700 on the backplate 110. A heat-dissipating silicone rubber 720 is disposed between the radiator 700 and the backplate 110, with its two sides respectively contacting the radiator 700 and the backplate 110.
[0054] See also Figure 1 and Figure 3In some embodiments, the slow-running light further includes a translucent mask 600, which is located in front of the light outlet 401 of the projection lamp module 400 and in front of the light outlet surface 320 of the light diffuser 300. The translucent mask 600 has a planar translucent structure 610, which is arranged opposite to the light outlet 401 of the projection lamp module 400. It can be understood that because the translucent mask 600 covers the light outlet 401 of the projection lamp module 400 and the light outlet surface 320 of the light diffuser 300, the translucent mask 600 can protect the projection lamp module 400 and the light diffuser 300, and at the same time, light passing through the translucent mask 600 will not affect the light output of the projection lamp module 400 and the light diffuser 300. Because the area of the light-transmitting mask 600 opposite the light outlet 401 of the projection lamp module 400 comprises a planar light-transmitting structure 610, the pattern or design projected by the projection lamp module 400 can be projected to the outside world through the planar light-transmitting structure 610, effectively minimizing distortion of the pattern or logo. The light-transmitting mask 600 is a light-transmitting resin mask, manufactured through an injection molding process using a resin such as PC or PMMA. This provides the light-transmitting mask 600 with excellent light transmission, mechanical properties, heat resistance, and weather resistance. Furthermore, both the outer and inner surfaces of the light-transmitting mask 600 have a mirror-like finish, without any optical patterns or sun marks.
[0055] See also Figure 3 In this embodiment, the inner surface of the light-transmitting mask 600 is recessed to form a light-entering plane portion, and the outer surface of the light-transmitting mask 600 is recessed to form a light-emitting plane portion. The light-entering plane portion and the light-emitting plane portion correspond to each other and are parallel to each other, forming a planar light-transmitting structure 610. It can be understood that the pattern or logo projected by the projection lamp module 400 enters the planar light-transmitting structure 610 through the light-entering plane portion and is then projected to the outside world through the light-emitting plane portion. This can reduce the distortion of the pattern or logo. The depth of the recessed light-entering plane portion ranges from 0.1mm to 0.5mm, and the diameter ranges from 5mm to 20mm; the depth of the recessed light-emitting plane portion ranges from 0.1mm to 0.5mm, and the diameter ranges from 5mm to 20mm.
[0056] See also Figure 3In some embodiments, the outer periphery of the light-splitting baffle 500 is formed with a circle of mounting edge 540 near the light-transmitting mask 600. A circle of glue retention groove 503 is formed on the light-splitting baffle 500 along the mounting edge 540. The edge of the light-transmitting mask 600 presses against the mounting edge 540 and covers the glue retention groove 503. It can be understood that because the edge of the light-transmitting mask 600 presses against the mounting edge 540 and covers the glue retention groove 503, the glue in the glue retention groove 503 can be cured on the edge of the light-transmitting mask 600 and the mounting edge 540, and the glue is not likely to overflow from the glue retention groove 503. Alternatively, the glue retention groove 503 can temporarily store welding residue to reduce the impact of the glue and welding residue on the optical illumination effect or the appearance of the slow-moving lamp.
[0057] Generally, due to the size limitation of the rearview mirror body 10, the projection lamp module 400 and the focusing inner lens 200 often need to be set close together, which makes the edge of the pattern projected by the projection lamp module 400 be projected onto the light homogenizer 300 in front of the focusing inner lens 200. In this way, the light distribution of the edge 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 the edge of the pattern projected by the projection lamp module 400 to be deformed.
[0058] See also Figure 4 In order to reduce the deformation of the edge of the pattern projected by the projection lamp module 400, in some embodiments, the projection lamp module 400 is arranged obliquely with respect to the focusing inner lens 200; the light outlet 401 of the projection lamp module is located in front of the light outlet surface 320 of the light diffuser 300, and an angled gap 402 is formed between the side wall of the projection lamp module and the side wall of the light diffuser 300; a light blocking portion 530 is formed on the light splitting baffle 500; an extended end of the light blocking portion 530 is located in the angled gap 402 and extends behind the concave-convex light incident surface 310 of the light diffuser 300.
[0059] It can be understood that since the projection lamp module 400 is arranged at an angle to the focusing inner lens 200, specifically, one end of the light outlet 401 of the projection lamp module 400 away from the shadow lamp module is arranged close to the light incident surface of the focusing inner 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 inclined in a direction away from the light homogenizer 300, thereby forming an inclined gap 402 between the side wall of the shadow lamp module and the side wall of the light homogenizer 300, thereby making the pattern projected by the light outlet 401 of the shadow lamp module away from the light homogenizer 300, thereby reducing the light at the edge of the pattern projected by the projection lamp module 400 from propagating toward the light homogenizer 300. Subsequently, because the extended end of the light blocking portion 530 on the light-splitting baffle 500 is disposed within the angled gap 402 and extends to the concave-convex light incident surface 310 of the light diffuser 300, the light at the edge of the pattern projected by the lamp module 400 is blocked by the light blocking portion 530. This separates the light outlet 401 of the lamp module 400 from the light diffuser 300, further reducing the transmission of light at the edge of the pattern projected by the lamp module 400 toward the light diffuser 300. The first portion of the light-splitting baffle 500 is located between the lamp module 400 and the translucent mask 600, and the second portion of the light-splitting baffle 500 is located between the light outlet surface 320 of the light diffuser 300 and the translucent mask 600.
[0060] Typically, a car is equipped with rearview mirrors on both sides. In order to reduce wind resistance during driving, the outer surfaces of the rearview mirror bodies 10 located at different positions of the car need to be designed with different curved structures according to the wind resistance conditions. This will cause the internal space of the rearview mirror bodies 10 located at different positions of the car to change. In other words, the structures of the focusing inner lenses 200 installed on the left and right sides of the car are different. When the rearview mirrors are assembled in batches, the focusing inner lenses 200 and the rearview mirror bodies 10 located on different sides of the car are easily installed incorrectly, thereby affecting the assembly efficiency of the rearview mirrors.
[0061] To reduce the possibility of mis-assembly of the focusing inner lens 200 and the rearview mirror body 10, please refer to Figure 4In some embodiments, a second adapting structure 520 is formed on the beam-splitting barrier 500. The second adapting structure 520 is adapted to the concave and convex sides of the focusing inner lens 200. It is understood that the concave and convex adaptation of the second adapting structure 520 to the focusing inner lens 200 enables the focusing inner lens 200 to be installed on the beam-splitting barrier 500. In this embodiment, the internal contour of the second adapting structure 520 is adapted to the external contour of the focusing inner lens 200. However, the contours of the focusing inner lenses 200 in the left and right slow-running lights of the vehicle are inconsistent. Therefore, the second adapting structure 520 formed on the beam-splitting barrier 500 in the slow-running light on the left side of the vehicle can only adapt to the focusing inner lens 200 on the corresponding side, thereby effectively preventing the focusing inner lenses 200 from rotating or being mixed up on the left and right sides. Specifically, the second adapting structure 520 is a positioning groove structure, but this is not a limitation, and those skilled in the art may also make other choices.
[0062] Typically, a car is provided with rearview mirrors on both sides. In order to reduce wind resistance during driving, the outer surfaces of the rearview mirror bodies 10 located at different positions of the car need to be designed with different curved structures according to the wind resistance conditions. This will cause the internal space of the rearview mirror bodies 10 located at different positions of the car to change. That is, the structures of the projection lamp modules 400 installed on the left and right sides of the car are different. When the rearview mirrors are assembled in batches, the projection lamp modules 400 and the rearview mirror bodies 10 located on different sides of the car are easily installed incorrectly, thereby affecting the assembly efficiency of the rearview mirrors.
[0063] To reduce the possibility of mis-installation of the projection lamp module 400 and the rearview mirror body 10, please refer to Figure 4 In some embodiments, a first adapting structure 510 is formed on the beam-splitting baffle 500, and the first adapting structure 510 is adapted to fit the projection lamp module 400 in a concave-convex manner. It can be understood that the concave-convex adaptation of the first adapting structure 510 to the projection lamp module 400 enables the projection lamp module 400 to be installed on the beam-splitting baffle 500. In this embodiment, the internal contour of the first adapting structure 510 matches the external contour of the projection lamp module 400. However, the contours of the projection lamp modules 400 in the left and right running lights of the vehicle are inconsistent. Therefore, the first adapting structure 510 formed on the beam-splitting baffle 500 in the left running light of the vehicle can only fit the projection lamp module 400 on the corresponding side, thereby effectively preventing the projection lamp modules 400 from rotating or being mixed up on the left and right sides. Specifically, the first adapting structure 510 is a positioning groove structure, but this is not limited here, and those skilled in the art may also make other choices.
[0064] Generally, in order to reduce the wind resistance during the driving of the car, the outer surface of the rearview mirror body 10 needs to be designed as a curved surface. Especially in some positions with larger curvature, the projection lamp module 400 needs to maintain a sufficiently large inclination angle relative to the focusing inner lens 200, that is, the inclination gap 402 formed between the side wall of the projection lamp module 400 and the side wall of the light homogenizer 300 is increased, so that the projection lamp module 400 and the focusing inner lens 200 can be installed at the position with larger curvature on the rearview mirror body 10. However, after the projection lamp module 400 projects the pattern, the distance between the pattern and the bright area formed by the projection of the light homogenizer 300 will increase, and the brightness compensation of the pattern by the bright area will be less, resulting in a decrease in the brightness of the pattern.
[0065] See also Figure 4 and Figure 5 In order to reduce the distance between the pattern and the bright area projected by the light homogenizer 300, in one embodiment, a mounting channel 601 is opened on the light-transmitting mask 600 at a position corresponding to the first light exit window 501; the planar light-transmitting structure 610 has a planar light entrance portion 6110 and a planar light exit portion 6120 that are parallel to each other, and the planar light-transmitting structure 610 is installed in the mounting channel 601, and the arcuate outer peripheral portion 6130 of the planar light-transmitting structure 610 slides with the arcuate inner peripheral wall of the mounting channel 601; the light exit port 401 of the projection lamp module 400 passes through the first light exit window 501 and is close to the planar light entrance portion 6110 of the planar light-transmitting structure 610; the arcuate outer peripheral portion 6130 of the planar light-transmitting structure 610 slides relative to the arcuate inner peripheral wall of the mounting channel 601, so that the planar light entrance portion 6110 swings toward one side of the focusing inner lens 200.
[0066] It can be understood that since the arcuate outer portion 6130 of the planar light-transmitting structure 610 slides in conjunction with the arcuate inner wall of the mounting channel 601, when the distance between the pattern projected by the projection lamp module 400 and the bright area formed by the projection through the light-uniform plate 300 is too large, the arcuate outer portion 6130 of the planar light-transmitting structure 610 can be adjusted to slide relative to the arcuate inner wall of the mounting channel 601, so that the planar light-entering portion 6110 swings toward one side of the focusing inner lens 200, thereby enabling the pattern projected by the projection lamp module 400 to be projected forward of the focusing inner lens 200 through the planar light-transmitting structure 610, thereby reducing the distance between the pattern projected by the projection lamp module 400 and the bright area formed by the projection through the light-uniform plate 300.
[0067] Generally, since a car is prone to bumping while driving, the planar light-transmitting structure 610 is prone to shaking in the installation channel 601, causing the pattern projected by the planar light-transmitting structure 610 to shake on the lane, thereby affecting the safe driving of other vehicles on the lane.
[0068] See also Figure 5 and Figure 6 In order to reduce the shaking of the planar light-transmitting structure 610 in the installation channel 601, in one embodiment, a stopping boss 6131 is formed on the arc-shaped outer peripheral portion 6130 of the planar light-transmitting structure 610, and a guide sliding groove 6011 and a plurality of hovering slots 6012 are opened on the arc-shaped inner peripheral wall of the installation channel 601. The stopping boss 6131 is slidably set in the guide sliding groove 6011, and the plurality of hovering slots 6012 are arranged at intervals along the sliding path of the stopping boss 6131, and each hovering slot 6012 is respectively connected to the guide sliding groove 6011; the hovering slot 6012 is used to clamp the stopping boss 6131 to enable the planar light-transmitting structure 610 to maintain a fixed swing angle.
[0069] It can be understood that since the stopping boss 6131 is slidably set in the guide groove 6011, when it is necessary to adjust the planar light input portion 6110 to swing toward the side of the focusing inner lens 200, the stopping boss 6131 can be guided to slide through the guide groove 6011, so that the planar light-transmitting structure 610 can swing stably in the installation channel 601. After the planar light input portion 6110 is swung into place toward the side of the focusing inner lens 200, the planar light-transmitting structure 610 can be twisted so that the stopping boss 6131 enters and is stuck in the hovering groove 6012, thereby making the planar light-transmitting structure 610 maintain a fixed swing angle in the installation channel 601.
[0070] See also Figure 5 Furthermore, in order to increase the stability of the swing angle of the planar light-transmitting structure 610 in the mounting channel 601, in one embodiment, the number of the stop bosses 6131 is two, the two stop bosses 6131 are coaxially arranged, and the axes O of the two stop bosses 6131 are inclined toward the direction of the focusing inner lens 200. It can be understood that since the two stop bosses 6131 are coaxially arranged and the axes of the two stop bosses 6131 are inclined toward the direction of the focusing inner lens 200, when it is necessary to adjust the plane light input portion 6110 to swing toward one side of the focusing inner lens 200, the two stop bosses 6131 can synchronously swing in the corresponding guide slide groove 6011. After the plane light input portion 6110 is swung into place toward one side of the focusing inner lens 200, the plane light-transmitting structure 610 can be twisted so that the two stop bosses 6131 can synchronously enter and be stuck in the corresponding hovering slot 6012 respectively. Finally, the two stop bosses 6131 can make the swing angle of the plane light-transmitting structure 610 in the installation channel 601 more stable.
[0071] See also Figure 4Furthermore, the light outlet 401 of the projection lamp module 400 and the light outlet surface 320 of the light diffuser 300 are located in the same plane or in different planes. The back panel 110 is a circuit board, and at least one lamp bead 120 on the circuit board corresponds to the light entrance of the projection lamp module 400. The light entrance of the projection lamp module 400 is arranged in close contact with the back panel 110, which can reduce light leakage from the lamp bead 120. The back panel 110 can be a single piece or split into two pieces to flexibly meet different target ground light spots and space requirements of the rearview mirror body 10.
[0072] In some embodiments, the outer surface of the light-transmitting mask 600 is a flat surface, and the outer surface of the light-transmitting mask 600 is used to be flush with the outer surface of the rearview mirror body 10. It can be 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 outer surface of the light-transmitting mask 600 and the outer surface of the rearview mirror body 10 can be made uniform in appearance, thereby reducing wind resistance when the car is driving.
[0073] See also 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 is understood that, because the outer surface of the light-transmitting mask 600 is recessed below the outer surface of the rearview mirror body 10, the outer surface of the light-transmitting mask 600 is not directly visible to the observer in a specified area. The specified area complies with the provisions 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 will be appreciated 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 fully curved surface on its outer surface, which can better adapt to airflow and further reduce wind resistance during vehicle driving. The curved surface is achieved by offsetting the outer surface of the light-transmitting mask 600 outwardly toward the light source 100 in a range of 0.1 mm to 10 mm.
[0075] See also Figure 2 In this embodiment, the vertical cross-section of the concave-convex light incident surface 310 is wavy. It can be understood that since the vertical cross-section of the concave-convex light incident surface 310 is wavy, the light in the light scattering gap 201 can be refracted and diffused by the concave-convex light incident surface 310.
[0076] In some embodiments, the cross-section of the concave-convex light incident surface 310 is sawtooth-shaped. It can be understood that since the vertical cross-section of the concave-convex light incident surface 310 is sawtooth-shaped, the concave-convex light incident surface 310 can refract and diffuse the light in the light scattering gap 201.
[0077] See also Figure 1 In this embodiment, linear stripes are provided on the concave-convex light incident surface 310. It can be understood that the linear stripes provided on the concave-convex light incident surface 310 can create a directional light distribution for the light received by the concave-convex light incident surface 310, which is suitable for emphasizing the directionality and layering of the light. The height of the linear stripes ranges from 0.3mm to 2mm.
[0078] In some embodiments, a grid pattern is provided on the concave-convex light incident surface 310. It is understood that the grid pattern on the concave-convex light incident surface 310 can provide a more uniform spot of light received by the concave-convex light incident surface 310, suitable for large-area lighting needs. The height of the grid pattern ranges from 0.3 mm to 2 mm.
[0079] In some embodiments, the concave-convex light incident surface 310 is provided with diamond patterns. It is understood that the diamond patterns on the concave-convex light incident surface 310 can create a light spot with a specific geometric shape in the light received by the concave-convex light incident surface 310, which is suitable for lighting scenarios requiring specific geometric effects. The height of the diamond patterns ranges from 0.3 mm to 2 mm.
[0080] In some embodiments, circular patterns are provided on the concave-convex light incident surface 310. It is understood that the circular patterns provided on the concave-convex light incident surface 310 can provide a softer distribution of light received by the concave-convex light incident surface 310. The height of the circular patterns ranges from 0.3 mm to 2 mm.
[0081] See also Figures 1 to 3 The present disclosure also provides a rearview mirror lighting device, comprising a rearview mirror body 10 and a slow-running light according to any of the above-described embodiments; the slow-running light is mounted on the rearview mirror body 10. It is understood that by applying the slow-running light of the present disclosure to the rearview mirror lighting device, light energy emitted by the light source 100 is focused within the light-scattering gap 201 by the focusing action of the focusing inner lens 200. The light is then refracted and diffused on the concave-convex light-incident surface 310 of the light-homogenizing sheet 300. The diffused light can be projected more evenly through the light-homogenizing sheet 300. For example, when camping outdoors, users can use the slow-running light to provide ground lighting.
[0082] See also Figures 1 to 3 The present disclosure also provides an automobile, including a rearview mirror lighting device according to any of the aforementioned embodiments. It is understood that by incorporating the rearview mirror lighting device of the present disclosure into an automobile, the automobile is not limited to components such as wheels, steering wheels, and powertrains. The automobile can be a fuel-powered vehicle, an electric vehicle, a hybrid vehicle, and is not limited to a sedan, SUV, MPV, or other vehicle types. The aforementioned slow-moving light has a wider light output range and more uniform lighting effects, improving lateral nighttime visibility of the automobile body.
[0083] Compared with the prior art, the present disclosure has at least the following advantages:
[0084] The above-mentioned slow-running light, because the light source 100, the focusing inner lens 200, and the light homogenizer 300 are arranged in sequence, forms a light-scattering gap 201 between the concave-convex light-entry surface 310 of the light homogenizer 300 and the light-emitting surface of the focusing inner lens 200. This allows the light emitted by the light source 100 to converge within the light-scattering gap 201 through the focusing effect of the focusing inner lens 200. The light is then refracted and diffused on the concave-convex light-entry surface 310 of the light homogenizer 300. The diffused light can be projected more evenly through the light homogenizer 300. Compared with the prior art, the above-mentioned slow-running light has a wider light output range and more uniform light effect, which can improve the nighttime vision of the side of the vehicle body.
[0085] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person of ordinary skill in the art could make various modifications and improvements without departing from the spirit of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the present patent shall be determined by the appended claims.
