Description

Technical Field

[0001] The present application relates to the technical field of vehicle lamp structures, and in particular to a vehicle lamp module, a vehicle, and a method for controlling the vehicle lamp module. Background Art

[0002] With the continuous development of automotive lighting technology, personalized lighting effects are one of the development trends of automotive lighting. Unique lighting effects can not only meet customer needs, but also increase the aesthetics and personalization of the vehicle. The lighting effects of existing automotive lights are average and cannot meet user needs. Summary of the Invention

[0003] The embodiments of the present application provide a vehicle light module, a vehicle, and a method for controlling the vehicle light module, which enhance the intensity of emitted light, thereby enhancing the lighting effect presented by the pattern layer after the light source is lit.

[0004] In a first aspect, the present application provides an automotive lamp module comprising a light source and a lampshade. The light source is configured to emit light. The lampshade is provided with a patterned layer, the patterned layer comprising a light-transmitting area and a non-light-transmitting area. At least a portion of the light emitted by the light source directly strikes the lampshade, while the portion of the light striking the lampshade passes through the light-transmitting area and exits the automotive lamp module.

[0005] In the vehicle lamp module of the present application, at least part of the light emitted by the light source can directly illuminate the lampshade, specifically, most of the light emitted by the light source can directly illuminate the lampshade, that is, in the arrangement direction of the light source and the lampshade, no other devices (such as optical lenses) are provided between the light source and the lampshade, and most of the light emitted by the light source does not need to penetrate other optical lenses and can directly illuminate the lampshade. In this way, under the same power consumption, the light intensity of the light emitted by the light source after exiting the light-transmitting area is effectively enhanced, thereby enhancing the lighting effect presented by the pattern layer after the light source is lit. When the light source is turned off, the non-light-transmitting area cannot transmit light, so that the vehicle lamp module presents a "night sky black" effect. Compared with the solution in which other optical lenses are provided between the light source and the lampshade, the vehicle lamp module of the present application can greatly reduce the power consumption of the light source, which is conducive to reducing costs.

[0006] In addition, since the pattern layer is directly set on the lampshade, when the light emitted by the light source is emitted from the lampshade through the light-transmitting area, the light-transmitting area can present a lighting effect with changing brightness when observed from different angles, making the lighting effect of the headlight module more dynamic and enhancing the technological sense and visual experience of the headlight module.

[0007] With reference to the first aspect, in a possible implementation, there are multiple light-transmitting areas, and a size of at least one of the multiple light-transmitting areas is different from sizes of the remaining light-transmitting areas.

[0008] By controlling the sizes of the multiple light-transmitting areas, at least one of them differs from the others. This creates a dazzling starry sky effect when the light source is illuminated, improving the aesthetics of the light module. Furthermore, the majority of the light emitted by the light source directly strikes the lampshade, effectively enhancing the dazzling starry sky effect when the light source is illuminated.

[0009] In combination with the first aspect, in a possible implementation, the maximum diameter of each light-transmitting area is greater than or equal to 0.5 mm and less than or equal to 1.9 mm.

[0010] Against the backdrop of the non-transparent area, when the light emitted by the light source is emitted from the transparent area with a smaller diameter, it can effectively enhance the lighting effect presented by the pattern layer.

[0011] In combination with the first aspect, in a possible implementation, the light-transmitting area is a through hole that penetrates the pattern layer.

[0012] The patterned layer can be created by spraying paint or applying a film, creating a non-transparent area. Then, holes are punched in the patterned layer to create a translucent area, exposing the portion of the lampshade that was previously obscured by the patterned layer. This allows light from the light source to pass through the translucent area and out through the exposed portion of the lampshade to the exterior of the lamp module.

[0013] With reference to the first aspect, in a possible implementation, the color of the non-light-transmitting area includes at least one of black, dark blue, dark gray, and dark green.

[0014] The non-light-transmitting area can be achieved by spray painting or film, so that the non-light-transmitting area appears dark through the color of the paint or the color of the film. When the light source is turned off, the headlight module can present a "night sky black" effect.

[0015] In combination with the first aspect, in a possible implementation, the lampshade is a transparent lampshade, and a pattern layer is provided on a surface of the lampshade facing the light source.

[0016] The side of the lampshade facing the light source is the light-facing side of the lampshade, and the side of the lampshade facing away from the light source is the backlight side. A patterned layer is provided on the light-facing side so that the non-light-transmitting areas on the patterned layer can absorb stray light emitted by the light source, reducing glare caused by multiple reflections within the transparent lampshade. The light-transmitting and non-light-transmitting areas form a contrast between light and dark, making the edges of the light-transmitting areas of the patterned layer sharper, which helps to enhance the three-dimensional effect of light and optimize the visual effect. Moreover, when observing the headlight module from the outside, because the patterned layer is provided on the light-facing side of the lampshade, even if the lampshade itself reflects a small amount of external ambient light, when light enters from the backlight side of the lampshade and penetrates the transparent material of the lampshade to reach the patterned layer, the non-light-transmitting areas of the patterned layer will absorb the light, resulting in very little light passing through. When the light source is turned off, the lampshade mainly presents the visual effect corresponding to the non-light-transmitting areas.

[0017] In combination with the first aspect, in a possible implementation, the lampshade includes a first side and a second side that are relatively arranged. In the direction from the first side toward the second side, the closer the multiple light-transmitting areas are to the second side, the greater the density of the multiple light-transmitting areas. The direction from the first side toward the second side is different from the arrangement direction of the light source and the lampshade.

[0018] Viewed from the outside of the entire headlight module, the density of the light-transmitting area near the second side is greater than that near the first side. When the light source is turned on, the lampshade can present a brilliant starry lighting effect, enhancing the aesthetics of the headlight module.

[0019] In combination with the first aspect, in a possible implementation, the vehicle lamp module further includes a fixing frame, which is connected and fixed to the lampshade to form an accommodating cavity, and the accommodating cavity accommodates the light source.

[0020] In combination with the first aspect, in a possible implementation, the vehicle lamp module further includes a circuit board, which is accommodated in the accommodating cavity. The circuit board is provided with a plurality of light sources, and the plurality of light sources on the circuit board are arranged opposite to the pattern layer.

[0021] The light source and the pattern layer are arranged opposite to each other, and there is no other optical lens between the light source and the pattern layer. Each light source can emit light directly and most of the emitted light directly hits the pattern layer, so that the light intensity emitted from the light-transmitting area is higher, enhancing the lighting effect presented by the pattern layer and helping to reduce the power consumption of the light source.

[0022] In combination with the first aspect, in a possible implementation, at least part of the multiple light sources are configured to emit light alternately.

[0023] At least part of the multiple light sources can realize alternating breathing and lighting of the local light sources, which can present the twinkling light effect of the starry sky in the local area, making the car light module more natural like the starry sky.

[0024] In combination with the first aspect, in a possible implementation, the fixing frame includes a mounting plate and a side plate, the mounting plate and the circuit board are stacked and connected and fixed, a light source is provided on the side of the circuit board facing away from the mounting plate, the side plate is provided on the edge of the mounting plate facing the lampshade and is connected and fixed to the lampshade, and a reflective layer is provided on the side of the side plate facing the accommodating cavity, the reflective layer is used to reflect part of the light emitted by the light source and illuminate the lampshade.

[0025] The mounting plate and the side plate together form a receiving cavity with an opening, and the lampshade is covered on the end of the side plate away from the mounting plate to form a closed receiving cavity. The side of the side plate facing the receiving cavity is the inner wall surface of the side plate. When the light source accommodated in the receiving cavity is lit, part of the light will shine on the inner wall surface of the side plate. Since the inner wall surface of the side plate is provided with a reflective layer, the light shining on the reflective layer will be reflected by the reflective layer and shine on the lampshade, which is conducive to enhancing the intensity of the light emitted from the light-transmitting area, thereby enhancing the lighting effect presented by the pattern layer.

[0026] With reference to the first aspect, in a possible implementation, along an arrangement direction of the light source and the lampshade, a minimum distance between the light source and the lampshade is greater than or equal to 17.41 mm.

[0027] The distance between the light source and the lampshade, along their arrangement, is defined as the distance between the point on the light source closest to the lampshade and the side of the lampshade facing the light source. The minimum distance between the light source and the lampshade is defined as the straight-line distance between the point on the side of the lampshade facing the light source closest to the light source and the point on the lampshade closest to the light source. The minimum distance between the light source and the lampshade is greater than or equal to 17.41mm. This prevents the light source and lampshade from being too close together, reduces the impact of excessive divergence of light emitted by the light source on the light intensity emitted from the light-transmitting area, and improves the intensity of the emitted light.

[0028] In a second aspect, the present application provides a vehicle comprising a vehicle body and a headlight module according to any implementation of the first aspect, wherein the headlight module is mounted on the vehicle body.

[0029] In a third aspect, the present application provides a control method for a vehicle light module, wherein the vehicle light module includes a plurality of light sources and a lampshade, and the plurality of light sources are used to emit light. The lampshade is provided with a patterned layer, and the patterned layer includes a light-transmitting area and a non-light-transmitting area. At least part of the light emitted by the light source is directly irradiated to the lampshade, and part of the light irradiated to the lampshade is emitted to the outside of the vehicle light module after passing through the light-transmitting area. The control method includes: controlling the first light source group to light up for a first preset time and then turn off; controlling the second light source group to light up for a second preset time immediately after the first light source group is turned off, and the second light source group and the first light source group belong to at least part of the multiple light sources; and cyclically executing the above steps to achieve alternating light emission of at least part of the multiple light sources.

[0030] By controlling at least part of the multiple light sources to light up alternately, the lampshade can present a lighting effect of alternating breathing of local areas of the starry sky after the light source is lit, just like the lighting effect of twinkling stars in local areas of the starry sky, making the lampshade more natural like a sky full of stars when the light source is lit.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0042] See also Figure 1 , Figure 1 Schematic diagram of an application scenario of the vehicle light module 10 provided in one embodiment of the present application. The vehicle light module 10 is applied to a vehicle 100, and the vehicle 100 includes a vehicle body 20 and the vehicle light module 10, and the vehicle light module 10 is installed on the vehicle body 20. The vehicle light module 10 can be installed on the outside of the vehicle body 20, for example, the vehicle light module 10 is set at the front light of the vehicle body 20, or can be set at the rear light of the vehicle body 20; or, the vehicle light module 10 can be set on the top, side or other positions of the vehicle body 20, and can be used as an atmosphere light. In other embodiments, the vehicle light module 10 can also be installed inside the vehicle body 20 as an interior atmosphere light, which is not specifically limited.

[0043] The vehicle 100 may include, but is not limited to, a commercial vehicle, a passenger car, a truck, a bus, a ship, an airplane, a helicopter, an RV, a train, and the like.

[0044] With the continuous development of automotive lighting technology, personalized lighting effects are one of the development trends of automotive lighting. Unique lighting effects can not only meet customer needs, but also increase the aesthetics and personalization of the vehicle. The lighting effects of existing automotive lights are average and cannot meet user needs.

[0045] To solve the above problems, the present application provides a vehicle lamp module 10 , which can enhance the intensity of emitted light, thereby enhancing the lighting effect presented by the pattern layer 121 of the vehicle lamp module 10 after the light source 11 is turned on.

[0046] See also Figure 2 and Figure 3 , Figure 2 A schematic structural diagram of a vehicle light module 10 provided in one embodiment of the present application; Figure 3 This is a schematic diagram of the structure of a lampshade 12 provided in one embodiment of the present application. The vehicle light module 10 includes a light source 11 and a lampshade 12. The light source 11 is configured to emit light. The lampshade 12 is positioned opposite the light source 11 and includes a patterned layer 121. The patterned layer 121 includes a light-transmitting area 1211 and a non-light-transmitting area 1212. At least a portion of the light emitted by the light source 11 directly strikes the lampshade 12. The portion of light that strikes the lampshade 12 passes through the light-transmitting area 1211 and exits the vehicle light module 10.

[0047] In the present application, at least part of the light emitted by the light source 11 can directly irradiate the lampshade 12, specifically, most of the light emitted by the light source 11 can directly irradiate the lampshade 12, that is, in the arrangement direction of the light source 11 and the lampshade 12 (such as Figure 2 In the X direction shown in the figure, no other devices (such as optical lenses) are provided between the light source 11 and the lampshade 12. Most of the light emitted by the light source 11 does not need to penetrate other optical lenses and can directly irradiate the lampshade 12. In this way, under the same power consumption, the light intensity of the light emitted by the light source 11 after exiting the light-transmitting area 1211 is effectively enhanced, thereby enhancing the lighting effect presented by the pattern layer 121 after the light source 11 is lit. When the light source 11 is turned off, the non-light-transmitting area 1212 cannot transmit light, so that the car light module 10 presents a "night sky black" effect. Compared with the solution in which other optical lenses are provided between the light source 11 and the lampshade 12, the car light module 10 of the present application can greatly reduce the power consumption of the light source 11, which is conducive to reducing costs.

[0048] In addition, since the patterned layer 121 is directly arranged on the lampshade 12, when the light emitted by the light source 11 is emitted from the lampshade 12 through the light-transmitting area 1211, the light-transmitting area 1211 can present a lighting effect with changing brightness when observed from different angles, so that the lighting effect of the car light module 10 can make the car light more dynamic, thereby enhancing the technological sense and visual experience of the car light module 10.

[0049] Please combine Figure 4 , Figure 4 This is a schematic diagram of the structure of the light source 11 provided in one embodiment of the present application. The light source 11 can be a light emitting diode (LED). There are multiple light sources 11, and the multiple light sources 11 can be arranged in a row and spaced apart. The arrangement length of the multiple light sources 11 can be determined according to the arrangement length of the pattern layer 121, so that the pattern layer 121 is directly opposite to at least one light source 11 along the arrangement direction of the light source 11 and the lampshade 12, so as to enhance the intensity of light emitted from the light-transmitting area 1211. The multiple light sources 11 can also be arranged in multiple columns, with multiple light sources 11 spaced apart in each column. The arrangement lengths of the multiple columns of light sources 11 can be the same or different, and are not specifically limited.

[0050] The length and width of the light source 11 may be 1.5mm*1.5mm, 2mm*2mm, 2.5mm*2.5mm or 3mm*3mm.

[0051] When there are multiple light sources 11, at least some of the multiple light sources 11 are used to alternately emit light. For example, after being lit, some of the multiple light sources 11 are in a constant light state, while another part of the multiple light sources 11 are used to alternately emit light, so that local light sources 11 are alternately lit. This can create a twinkling light effect of a starry sky in a local area, making the vehicle light module 10 more natural and reminiscent of a sky full of stars. The alternating lighting of at least some of the multiple light sources 11 can be achieved by controlling the circuit of the multiple light sources 11 to achieve alternating breathing lighting.

[0052] In one embodiment, along the arrangement direction of the light source 11 and the lampshade 12, the minimum distance between the light source 11 and the lampshade 12 is greater than or equal to 17.41 mm, wherein along the arrangement direction of the light source 11 and the lampshade 12, the distance between the light source 11 and the lampshade 12 refers to: the distance between the point of the light source 11 closest to the lampshade 12 and the side of the lampshade 12 facing the light source 11. The minimum distance between the light source 11 and the lampshade 12 is: the straight-line distance between the point on the side of the lampshade 12 facing the light source 11 closest to the light source 11 and the point on the light source 11 closest to the lampshade 12, as shown in FIG. Figure 2 As shown in D1.

[0053] The minimum distance between the light source 11 and the lampshade 12 can be 17.41 mm, 17.80 mm, 18.00 mm, 18.20 mm, 18.50 mm, 19.10 mm, 19.35 mm, etc. The minimum distance between the light source 11 and the lampshade 12 is greater than or equal to 17.41 mm to prevent the light source 11 and the lampshade 12 from being too close, reduce the effect of excessive divergence of light emitted by the light source 11 on the intensity of light emitted from the light-transmitting area 1211, and help improve the intensity of the emitted light.

[0054] Please combine Figure 4 and Figure 5 , Figure 5 for Figure 3 The diagram shows an enlarged view of the lampshade 12 at point V. The lampshade 12 is transparent; that is, before the patterned layer 121 is provided, the lampshade 12 is transparent to light emitted by the light source 11. After the patterned layer 121 is provided, light emitted by the light source 11 passes through the light-transmitting area 1211 of the patterned layer 121 and exits the lampshade 12 to the exterior of the lighting module.

[0055] In one embodiment, a patterned layer 121 is provided on the side of the lampshade 12 facing the light source 11. The side of the lampshade 12 facing the light source 11 is the light-facing side, and the side of the lampshade 12 facing away from the light source 11 is the backlight side. The patterned layer 121 is provided on the light-facing side of the lampshade 12 so that the non-transparent area 1212 of the patterned layer 121 can absorb stray light emitted by the light source 11, reducing glare caused by multiple reflections within the transparent lampshade 12. Furthermore, the light-transparent area 1211 and the non-transparent area 1212 form a contrast between light and dark, making the edges of the light-transparent area 1211 of the patterned layer 121 sharper, which helps enhance the three-dimensional effect of light and optimizes the visual effect. When observing the headlight module 10 from the outside, since the patterned layer 121 is arranged on the light-facing surface of the lampshade 12, even if the lampshade 12 itself reflects a small amount of external ambient light, when the light enters from the backlight surface of the lampshade 12 and penetrates the transparent material of the lampshade 12 to reach the patterned layer 121, the non-light-transmitting area 1212 of the patterned layer 121 will absorb the light, so that very little light passes through. When the light source 11 is turned off, the lampshade 12 mainly presents the visual effect corresponding to the non-light-transmitting area 1212.

[0056] In one embodiment, the pattern layer 121 can be achieved by spray painting and laser engraving. Specifically, a non-transparent area 1212 is formed by spray painting on the light-facing surface of the lampshade 12, and then a translucent area 1211 is formed by laser engraving on the paint layer. The actual translucent area 1211 is a through hole that penetrates the pattern layer 121. That is, when the paint layer is laser engraved, the entire paint layer is penetrated, so that the portion of the lampshade 12 blocked by the paint layer is exposed. In this way, the light emitted by the light source 11 can pass through the translucent area 1211 and then be emitted from the exposed portion of the lampshade 12 to the outside of the vehicle lamp module 10. Among them, the non-translucent area 1212 and the translucent area 1211 as a whole present the pattern effect corresponding to the pattern layer 121.

[0057] In another embodiment, the pattern layer 121 can be implemented by applying a film. Specifically, a film layer is first applied to the light-facing surface of the lampshade 12 to form a non-light-transmitting area 1212. Then, holes are punched in the film layer to expose the portion of the lampshade 12 that is blocked by the film layer to form a light-transmitting area 1211. The actual light-transmitting area 1211 is a through hole that penetrates the pattern layer 121.

[0058] In the two aforementioned embodiments, since the non-transparent area 1212 is used to block light emitted by the light source 11 from passing through the lampshade 12, the colors of the paint and film are both dark. For example, the paint and film colors include at least one of black, dark blue, dark gray, and dark green. This results in the non-transparent area 1212 being at least one of black, dark blue, dark gray, and dark green. When the light source 11 is turned off, the dark non-transparent area 1212 enables the lamp module 10 to present a "night sky black" effect. Furthermore, dense and tiny translucent areas 1211 can be formed by laser engraving the paint layer or punching holes in the film layer. When the light source 11 is turned on, the lamp module 10 presents a natural starry sky effect.

[0059] There are multiple light-transmitting areas 1211, and the size of at least one of the multiple light-transmitting areas 1211 is different from the sizes of the other light-transmitting areas 1211. The light-transmitting areas 1211 can be circles, triangles or other irregular shapes. The size of the light-transmitting areas 1211 is the size of the area enclosed by the outer edges of the light-transmitting areas 1211, which can be the area size or the distance between the two points with the largest distance between the outer edges of the light-transmitting areas 1211. By controlling the sizes of the multiple light-transmitting areas 1211, the size of at least one of the multiple light-transmitting areas 1211 is different from the sizes of the other light-transmitting areas 1211, so that when the light source 11 is turned on, a brilliant starry sky car light effect is presented, which is beneficial to improving the aesthetics of the car light module 10. Moreover, most of the light emitted by the light source 11 directly shines on the lampshade 12, which can effectively enhance the brilliant starry sky car light effect when the light source 11 is turned on.

[0060] In one embodiment, the maximum diameter of each light-transmitting area 1211 is greater than or equal to 0.5 mm and less than or equal to 1.9 mm. When the shape of the light-transmitting area 1211 is a circle, the maximum diameter of the light-transmitting area 1211 is the diameter of the circle; when the light-transmitting area 1211 is a triangle or other polygon, the maximum diameter of the light-transmitting area 1211 is the length of the longest side of the triangle or polygon; when the light-transmitting area 1211 is other irregular shapes, the maximum diameter of the light-transmitting area 1211 is the distance between the two points with the largest spacing between the irregular shapes. For example, the maximum diameter of the light-transmitting area 1211 can be 0.5 mm, 0.6 mm, 0.76 mm, 0.82 mm, 0.9 mm, 1.0 mm, 1.3 mm, 1.45 mm, 1.53 mm, 1.68 mm, 1.8 mm, or 1.9 mm, etc. The maximum diameters of multiple light-transmitting areas 1211 can be in the range of [0.5 mm, 1.9 mm], which are not listed one by one. Against the backdrop of the non-transparent area 1212 , the light emitted by the light source 11 can effectively enhance the lighting effect presented by the pattern layer 121 when it is emitted from the transparent area 1211 with a smaller diameter.

[0061] like Figure 3 As shown, the lampshade 12 includes a first side 122 and a second side 123 that are oppositely disposed. The first side 122 and the second side 123 are both long sides of the lampshade 12 .

[0062] In one embodiment, the first side 122 and the second side 123 are connected by the third side 124 and the fourth side 125. The third side 124 and the fourth side 125 are located between the first side 122 and the second side 123. The first side 122, the second side 123, the third side 124, and the fourth side 125 collectively form the outer edge of the entire lampshade 12. From the first side 122 to the second side 123, the closer the multiple light-transmitting regions 1211 are to the second side 123, the greater the density of the multiple light-transmitting regions 1211. When viewed from the outside of the entire vehicle lamp module 10, the density of the light-transmitting regions 1211 near the second side 123 is greater than that near the first side 122. When the light source 11 is illuminated, the lampshade 12 can present a dazzling star-like lighting effect, enhancing the aesthetics of the vehicle lamp module 10. The direction from the first side 122 to the second side 123 is different from the arrangement direction of the light source 11 and the lampshade 12. For example, the direction from the first side 122 to the second side 123 is perpendicular to the arrangement direction of the light source 11 and the lampshade 12. When both the first side 122 and the second side 123 are curved, the direction from the first side 122 to the second side 123 includes multiple directions, each of which is different from the arrangement direction of the light source 11 and the lampshade 12.

[0063] In other embodiments, when the pattern formed by the outer contour of the lampshade 12 is an irregular shape, the first side 122 and the second side 123 are connected end to end to form the outer edge of the entire lampshade 12 .

[0064] See also Figure 2 and Figure 6 , Figure 6 This is a schematic diagram of the exploded structure of the light source 11 and mounting bracket 13 provided in one embodiment of the present application. In one embodiment, the vehicle lamp module 10 further includes a mounting bracket 13, which is connected and fixed to the lampshade 12 to form a receiving cavity 14, which houses the light source 11. The mounting bracket 13 is used to secure the lampshade 12 and the light source 11. The mounting bracket 13 has a U-shaped cross-section, securing the edges of the lampshade 12 while also controlling the spacing between the light source 11 and the lampshade 12.

[0065] The fixing frame 13 includes a mounting plate 131 and a side plate 132. The mounting plate 131 is used to mount the light source 11. The side plate 132 is arranged on the edge of the mounting plate 131 facing the lampshade 12, and the side plate 132 is connected and fixed to the lampshade 12. The mounting plate 131 and the side plate 132 are an integrally formed structure, and the mounting plate 131 and the side plate 132 together enclose a receiving cavity 14 with an opening. The lampshade 12 covers the end of the side plate 132 away from the mounting plate 131 to cover the opening and together with the fixing frame 13, form a closed receiving cavity 14. In this way, the light source 11 is accommodated in the closed receiving cavity 14, and the light emitted by the light source 11 is only emitted from the light-transmitting area 1211 to the outside, so that the light intensity emitted from the light-transmitting area 1211 is higher, thereby enhancing the contrast between light and dark, thereby enhancing the lighting effect presented by the pattern layer 121.

[0066] Furthermore, a reflective layer 15 is provided on the side of the side panel 132 facing the accommodating cavity 14. The reflective layer 15 is used to reflect a portion of the light emitted by the light source 11 and illuminate the lampshade 12. The side of the side panel 132 facing the accommodating cavity 14 is the inner wall surface of the side panel 132. When the light source 11 housed in the accommodating cavity 14 is illuminated, a portion of the light will illuminate the inner wall surface of the side panel 132. Because the inner wall surface of the side panel 132 is provided with the reflective layer 15, the light that hits the reflective layer 15 is reflected by the reflective layer 15 and then illuminates the lampshade 12, which helps to increase the intensity of the light emitted from the light-transmitting area 1211, thereby enhancing the lighting effect presented by the patterned layer 121.

[0067] In this embodiment, no other optical lenses are arranged between the light source 11 and the pattern layer 121 in the arrangement direction of the light source 11 and the lampshade 12. That is, the light emitted by the light source 11 does not need to penetrate other optical lenses and can directly illuminate the pattern layer 121. The light output angle will not be restricted, so that the light and dark contrast of the overall lighting effect is stronger.

[0068] In one embodiment, the vehicle lamp module 10 further includes a circuit board 16, which is housed in the receiving cavity 14 defined by the mounting bracket 13. Multiple light sources 11 are disposed on the circuit board 16, and the multiple light sources 11 on the circuit board 16 are positioned opposite the patterned layer 121. Because there are no optical lenses between the light sources 11 and the patterned layer 121, each light source 11 can emit light directly, with the majority of the emitted light directly impinging on the patterned layer 121. This results in higher light intensity from the light-transmitting area 1211, enhancing the lighting effect of the patterned layer 121 and reducing power consumption of the light sources 11.

[0069] Specifically, the circuit board 16 and the mounting plate 131 are stacked along the arrangement direction of the light source 11 and the lampshade 12. A plurality of light sources 11 are provided on the side of the circuit board 16 facing away from the mounting plate 131. The light sources 11 on the circuit board 16 are directly opposite to the patterned layer 121. No other devices are arranged between the light sources 11 on the circuit board 16 and the lampshade 12. Most of the light emitted by the light source 11 does not need to penetrate other optical lenses or be blocked by other components.

[0070] The number of the circuit boards 16 can be one or more. When the number of the circuit boards 16 is multiple, the surfaces of the multiple circuit boards 16 on which the light sources 11 are mounted can be located on the same plane, and each circuit board 16 is mounted with multiple light sources 11 .

[0071] See also Figure 7 , Figure 7 This is a flow chart of a control method for a vehicle light module 10 according to an embodiment of the present application. The control method for the vehicle light module 10 is used to control at least some of the multiple light sources 11 of the vehicle light module 10 to emit light alternately. The control method for the vehicle light module 10 includes steps S701-S703:

[0072] S701: Control the first light source group to light up for a first preset time and then turn off.

[0073] There may be one or more light sources 11 in the first light source group. When the light sources 11 in the first light source group execute step S701, the light sources 11 in the first light source group are lit at the same time and all maintain the first preset duration. Specifically, the driving circuit of each light source 11 is independently controllable, and the driving circuit of the light source 11 in the first light source group is controlled by the controller of the car light module 10, so that the first light source group is in a lit state within the first preset duration and is in an off state after the first preset duration. When the light source 11 of the first light source group is turned off, a first signal is sent to the controller of the car light module 10, so that the controller of the car light module 10 can control other light sources 11 in the multiple light sources 11 according to the signal. The first preset duration can be 3s, 5s or 8s, etc., and is not specifically limited.

[0074] In one embodiment, the light sources 11 in the first light source group are light sources 11 within one area of all the light sources 11. Specifically, all the light sources 11 are arranged in a matrix. For example, all the light sources 11 are arranged in a matrix of two rows and ten columns. The light sources 11 in the first light source group are a two-row, two-column matrix consisting of two rows of light sources 11 in the fourth column and the fifth column of all the light sources 11.

[0075] S702 : Controlling the second light source group to light up for a second preset time period immediately after the first light source group is turned off, the second light source group and the first light source group belonging to at least part of the plurality of light sources 11 .

[0076] The second light source group may include one or more light sources 11 . When the light sources 11 in the second light source group execute step S702 , the light sources 11 in the second light source group are simultaneously lit and all maintain the second preset duration.

[0077] Specifically, after receiving the signal from the first light source group, the controller of the vehicle light module 10 controls the driver circuit of the light source 11 in the second light source group, causing the second light source group to illuminate immediately after the first light source group is deactivated, and to remain on for a second preset duration. After the second preset duration has expired, a second signal is sent to the controller of the vehicle light module 10, allowing the controller of the vehicle light module 10 to control the illumination of the first light source group. The second preset duration can be the same as the first preset duration, or it can be different from the first preset duration. For example, the second preset duration can be 4 seconds, 6 seconds, or 9 seconds, etc., without limitation.

[0078] In one embodiment, the light sources 11 in the second light source group are light sources 11 within a certain region of all the light sources 11, and the region of the second light source group is different from the region of the first light source group. For example, all the light sources 11 are arranged in a two-row, ten-column matrix. The light sources 11 in the first light source group are the two-row, two-column matrix consisting of the two rows of light sources 11 located in the fourth and fifth columns of all the light sources 11. The light sources 11 in the second light source group are the two-row, two-column matrix consisting of the two rows of light sources 11 located in the seventh and eighth columns of all the light sources 11. For another example, all the light sources 11 are arranged in a two-row, ten-column matrix. The light sources 11 in the first light source group are the two-row, two-column matrix consisting of the two rows of light sources 11 located in the second and fifth columns of all the light sources 11. The light sources 11 in the second light source group are the two-row, two-column matrix consisting of the two rows of light sources 11 located in the third and sixth columns of all the light sources 11. By controlling at least part of the multiple light sources 11 to light up alternately, the lampshade 12 can present a lighting effect of alternating breathing of a local area of the starry sky after the light source 11 is lit, just like the lighting effect of a starry sky twinkling in a local area of the starry sky, making the lampshade 12 have a more natural effect of a sky full of stars when the light source 11 is lit.

[0079] S703: cyclically executing the above steps to achieve alternating lighting of at least part of the plurality of light sources 11.

[0080] The controller of the vehicle light module 10 loops through steps S701 and S702. For example, after the second light source group remains on for the second preset duration, the controller of the vehicle light module 10 controls the second light source group to be turned off and then immediately turns on the first light source group for the first preset duration. The controller then controls the second light source group to be turned on again for the second preset duration immediately after the first light source group is turned off.

[0081] In one embodiment, the total number of light sources 11 in the first and second light source groups is equal to the total number of light sources 11. In other embodiments, the number of light sources 11 in the first and second light source groups is less than the total number of light sources 11. At any given moment, light sources 11 that do not belong to the first or second light source groups are in an illuminated state. The permanently illuminated light sources 11 can maintain the basic lighting effect presented by the pattern layer 121, while the alternately flashing light sources 11 can present a dynamically changing lighting effect. The contrast between the permanently illuminated light sources 11 and the alternately flashing light sources 11 gives the vehicle light module 10 a three-dimensional effect of superimposed light and shadow.
