Description

[0001] The present application relates to the technical field of vehicle-mounted lamps, and in particular to a vehicle interior and exterior decoration and a lighting system device, an optical module, and a control method thereof. Background Art

[0002] Lighting systems can be integrated with exterior components such as bumpers, grilles, and door panels. Global automotive development is accelerating towards electrification and intelligentization, leading to significant design trends: front grilles becoming closed or eliminated, and lamps becoming narrower and longer. While smart electric vehicles demand a more dynamic lighting environment and V2X interaction, these trends are also driving a reduction in available lighting area, creating a conflicting environment.

[0003] Existing lighting systems work by transmitting light through a layer of translucent paint, semi-transparent material, or ink. The light changes with the original color of the medium. For example, if the translucent paint is red, white light passing through the paint will appear red, preventing the creation of rich and varied display effects.

[0032] According to another aspect of the present application, a vehicle interior is provided, comprising the lighting system device as described above.

[0033] The beneficial effects of this application include:

[0034] The present application provides a lighting system device, a light emitting unit and a cover plate, wherein the cover plate is used for light emission from the light emitting unit, and the cover plate includes a substrate, a primer layer, a color paint layer and a transparent paint layer stacked in sequence; the substrate is located between the primer layer and the light emitting unit, the primer layer is provided with a plurality of first light-transmitting holes, the color paint layer is provided with a plurality of second light-transmitting holes, at least some of the second light-transmitting holes are connected to at least some of the first light-transmitting holes, and the correspondingly connected first light-transmitting holes and second light-transmitting holes together form light-transmitting hole positions. Therefore, the present application uses a substrate, a primer layer, a color paint layer and a transparent paint layer stacked in sequence to enable the light emitted by the light emitting unit to display the color of the light unit itself through the light-transmitting hole position formed by the correspondingly connected first light-transmitting hole and the second light-transmitting hole, without being affected by the primer layer and the color paint layer. When the light emitting unit does not emit light, due to the size distribution of the first light-transmitting hole and the second light-transmitting hole, the transmittance of the first light-transmitting hole and the second light-transmitting hole is low, so that the cover plate can display the color of its own color paint layer as a whole, and its appearance is almost the same as the appearance without the first light-transmitting hole and the second light-transmitting hole, thereby hiding the light emitting unit behind the cover plate.

[0035] The present application also provides an optical module, comprising a plurality of light sources, and a silicone lens and a light guide member sequentially arranged on the light-emitting side of the light source; a plurality of light-guiding channels are provided on the light guide member; each light-guiding channel corresponds to at least one light source, and the silicone lens is used to converge the light beam so that the light emitted by each light source is incident on its corresponding light-guiding channel, and the light-guiding channel is used to collect the light of the corresponding light source and guide it for output. The present application adds a silicone lens between the light-emitting side of the light source and the light-entering side of the light guide member, so that the light emitted by the light source can be converged and focused, so that almost all the light enters the light-guiding channel of the light guide member, so that the brightness of a single display pixel can be increased by 200% compared to before the silicone lens is added, thereby effectively solving the problem in the prior art that the display pixel cannot achieve high-brightness uniform lighting of a low-power light source due to heat resistance (low-power light sources can only achieve high-brightness lighting by reducing the distance between light sources, but reducing the distance will lead to heat resistance). Furthermore, the silicone lens added in this application is lightweight and requires minimal space. Therefore, compared to increasing the brightness of display pixels by increasing the power of the light source, this configuration can reduce costs by approximately 50%. Therefore, this application can achieve high-brightness, uniform lighting with a low-power light source. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] This application provides a new lighting system device (non-traditional lighting fixture) that can emit light in the grille, bumper, exterior door panel lighting area, or other vehicle locations (such as interior lighting, ambient lighting, etc.). This device can meet styling requirements and achieve lighting display without affecting the color of the light due to the color of the cover itself. The specific structure of the new lighting system device provided by this application is described in detail below.

[0051] In one aspect of an embodiment of the present application, a lighting system device is provided. Please refer to Figures 1 and 2. The lighting system device includes a light output unit and a cover plate 70. The cover plate 70 is used for the optical module to output light. The cover plate 70 includes a substrate 71, a primer layer 72, a color paint layer 73 and a transparent paint layer 74 stacked in sequence; the substrate 71 is located between the primer layer 72 and the light output unit, and a plurality of first light-transmitting holes 721 are provided on the primer layer 72, and a plurality of second light-transmitting holes 731 are provided on the color paint layer 73. At least part of the second light-transmitting holes 731 are connected to at least part of the first light-transmitting holes 721, and the correspondingly connected first light-transmitting holes 721 and second light-transmitting holes 731 together form a light-transmitting hole position 75.

[0052] The present application sets a plurality of first light-transmitting holes 721 on the primer layer 72 and a plurality of second light-transmitting holes 731 on the color paint layer 73, and makes at least some of the first light-transmitting holes 721 and the second light-transmitting holes 731 correspondingly connected, so that the corresponding first light-transmitting holes 721 and the second light-transmitting holes 731 can form light-transmitting hole positions 75. In this way, the color paint layer 73 and the primer layer 72 can have multiple light-transmitting hole positions 75. In this way, the color of the light emitted by the light source 10 will not change with the original color of the above medium, thereby improving the display effect of the pixel display.

[0053] The present application uses a substrate 71, a primer layer 72, a color paint layer 73 and a transparent paint layer 74 stacked in sequence to ensure that when the light emitting unit emits light, the light emitted by the light emitting unit displays the color of the light unit itself through the first light-transmitting hole 721 and the second light-transmitting hole 731, without being affected by the primer layer 72 and the color paint layer 73; and when the light emitting unit does not emit light, due to the size distribution of the first light-transmitting hole 721 and the second light-transmitting hole 731, the transmittance of the first light-transmitting hole 721 and the second light-transmitting hole 731 is low, so that the cover plate 70 can display the color of its own color paint layer 73 as a whole, and its appearance is almost the same as the appearance without the first light-transmitting hole 721 and the second light-transmitting hole 731, and the light emitting unit behind the cover plate 70 can be hidden.

[0054] The light emitting unit includes at least a light source. For example, the light emitting unit may include only a light source. For another example, the light emitting unit may also include a light source and one or more optical elements, and the one or more optical elements may be primary optical elements or secondary optical elements, but the present application is not limited to this. The light emitting unit may include an optical module, and the optical module may have the same structure as the optical module used for car lights, interior lights, and ambient lights, but the present application is not limited to this. The present application does not limit the number of light sources in the light emitting unit. For example, the light emitting unit may include one light source, or the light emitting unit may include multiple light sources.

[0055] In some embodiments, the first light-transmitting holes 721 and the second light-transmitting holes 731 are arranged in a one-to-one correspondence in position. The present application is not limited thereto, and the number of the first light-transmitting holes 721 and the second light-transmitting holes 731 can be different.

[0056] In some embodiments, when the light output unit includes multiple light sources, the multiple light sources are aligned with the light transmission hole positions 75 formed by the first light transmission hole 721 and the second light transmission hole 731. However, the present application is not limited to this, and the multiple light sources may also be staggered with the light transmission hole positions 75 formed by the first light transmission hole 721 and the second light transmission hole 731.

[0057] In some embodiments, when the light emitting unit has multiple light sources, the light sources 10 of the light emitting unit can be individually controlled to display different pixel patterns through the first light-transmitting hole 721 and the second light-transmitting hole 731. However, the present application is not limited to this, and the light sources 10 of the light emitting unit can also be controlled uniformly.

[0058] Optionally, the first light-transmitting hole 721 and the second light-transmitting hole 731 are both formed by a laser process.

[0059] Optionally, in order to maintain the appearance of the cover plate and prevent the light-transmitting hole 75 from being visible, the aperture of the light-transmitting hole 75 may be between 10 μm and 400 μm.

[0060] Optionally, in order to maintain the appearance of the cover plate and prevent the light-transmitting holes 75 from being visible, the center distance between adjacent light-transmitting holes 75 may be between 100 μm and 1000 μm.

[0061] The laser process makes the cover plate 70 light-transmissive at the punched areas through punching. The larger the area ratio of the holes per unit area, the higher the transmittance, and the easier it is to identify the holes in the static appearance. Conversely, the smaller the area ratio of the holes per unit area, the lower the transmittance, and the holes are not easily identified in the static appearance, which can be consistent with the non-punched areas.

[0062] Optionally, the first light-transmitting hole 721 and the second light-transmitting hole 731 have the same shape and size, and the corresponding first light-transmitting hole 721 and the second light-transmitting hole 731 together form a light-transmitting hole position 75 .

[0063] According to research, when the aperture of the light-transmitting hole 75 and the center distance between two adjacent light-transmitting holes 75 have a certain numerical relationship, the transmittance and the static pinhole visibility are in a balanced state.

[0064] Referring to Figure 3 , the ratio of the aperture of the light-transmitting hole 75 to the center-to-center distance between two adjacent light-transmitting holes 75 is greater than or equal to 0.2. In this case, the transmittance of the cover plate 70 is high, the light-transmitting holes 75 can be clearly identified during the day, and the light-transmitting holes 75 can be clearly observed from a static appearance. In Figure 3 , the aperture of the light-transmitting hole 75 is 40 μm, the center-to-center distance between two adjacent light-transmitting holes 75 (hereinafter referred to as the center distance) is L = 200 μm, and D / L = 0.2. Therefore, in some preferred embodiments, the ratio of the aperture of the light-transmitting hole 75 to the center-to-center distance between two adjacent light-transmitting holes 75 can be less than or equal to 0.2 to avoid the situation where the light-transmitting holes 75 can be clearly observed from a static appearance.

[0065] Referring to Figure 4 , optionally, the ratio of the aperture of light-transmitting hole 75 to the center-to-center distance between two adjacent light-transmitting holes 75 is less than or equal to 0.2. For example, the ratio of the aperture of light-transmitting hole 75 to the center-to-center distance between two adjacent light-transmitting holes 75 is less than or equal to 0.1. In this case, the transmittance of cover plate 70 is low, and light-transmitting holes 75 can only be identified at night. Light-transmitting holes 75 are not observable during static appearance, resulting in an excellent static appearance. In Figure 4 , the aperture of light-transmitting hole 75 is 20 μm, the center-to-center distance L is 200 μm, and D / L is 0.1.

[0066] As shown in Figures 5 and 6, when the center distance L changes (from 200 μm to 100 μm), maintaining the numerical relationship between the aperture diameter of light-transmitting aperture 75 and the center distance L can achieve equivalent transmittance and static appearance. In Figure 5, the aperture diameter of light-transmitting aperture 75 is 20 μm, and the center distance L = 100 μm; in Figure 6, the aperture diameter of light-transmitting aperture 75 is 10 μm, and the center distance L = 100 μm.

[0067] 7 and 8, the light-transmitting holes 75 are not limited to circular, but can also be square or any other shape. Referring to FIG9 and 10, the arrangement of the plurality of light-transmitting holes 75 is not limited to a regular matrix arrangement, but can also be an irregular arrangement.

[0068] In some embodiments of the present application, a regular or irregular arrangement of multiple light-transmitting apertures 75 can enable the multiple light-transmitting apertures 75 to display pixelated graphics and animations. The shape of the light-transmitting apertures 75 can be coordinated with the arrangement to enhance the playback effect of the pixelated graphics and animations. In some embodiments, the light-transmitting apertures 75 can be, for example, triangular, and the multiple light-transmitting apertures 75 can be arranged in a parallelogram, with two sides of the parallelogram parallel to two sides of the triangle of the light-transmitting aperture 75, respectively, so as to present corresponding rows and columns of pixels. At the same time, because the rows and columns of pixels are not perpendicular, the pixels of adjacent rows or adjacent columns are staggered to improve the display continuity of the oblique lines in the graphics and increase the interest of the animation display. Furthermore, the triangular shapes of adjacent light-transmitting apertures 75 can be inverted, that is, arranged in a manner such that one adjacent light-transmitting aperture 75 is an equilateral triangle and the other adjacent light-transmitting aperture 75 is an inverted triangle, further reducing the jagged display of the oblique lines in the graphics and enhancing the playback effect of the pixelated graphics and animations. In some variations, the shapes of the light-transmitting holes 75 may also be different.

[0069] In some embodiments of the present application, each light-transmitting hole 75 can also be composed of multiple adjacent light-transmitting sub-holes, thereby increasing the light-transmitting area of ​​each light-transmitting hole 75. However, since the size of the light-transmitting sub-hole is small, the transmittance of each light-transmitting sub-hole is small, thereby reducing the visibility of the light-transmitting hole 75 when the optical module is not emitting light.

[0070] Furthermore, the relationship between the aperture, center distance L, shape of the light-transmitting holes 75, and arrangement of the plurality of light-transmitting holes 75 and the static appearance / transmittance can be further summarized as the ratio of the area of ​​the cover plate 70 occupied by the light-transmitting holes 75 per unit area.

[0071] The cover plate 70 has light-transmitting holes 75 of various shapes arranged in a predetermined pattern and evenly distributed. The relationship between the area occupied by the light-transmitting holes 75 per unit area (hole area / area occupied by hole distribution) and the static appearance / transmittance is as follows:

[0072] The first case: the area of ​​the multiple light-transmitting holes 75 on the cover plate 70 is less than or equal to 0.79% (that is, the area occupied by the light-transmitting holes 75 per unit area is ≤0.79%). At this time, the transmittance can only be identified at night, and the light-transmitting holes 75 cannot be observed in the static appearance. The static appearance is excellent.

[0073] The second situation: the area of ​​the multiple light-transmitting holes 75 on the cover plate 70 accounts for greater than or equal to 3.14% (that is, the area occupied by the light-transmitting holes 75 per unit area is ≥3.14%). At this time, the transmittance can be clearly identified during the day, and the light-transmitting holes 75 can be clearly observed in the static appearance, and the appearance effect is not perfect.

[0074] The third case: the area of ​​the plurality of light-transmitting holes 75 on the cover plate 70 accounts for between 0.79% and 3.14% (i.e., the area of ​​the light-transmitting holes 75 per unit area is between 0.79% and 3.14%). In this case, the transmittance and the static appearance are between the above two cases.

[0075] Therefore, in this embodiment, to ensure a better display effect, the area of ​​the plurality of light-transmitting holes 75 on the cover plate 70 may be less than or equal to 3.14%.

[0076] In addition, in actual implementation, the color paint layer 73 can be divided into ordinary paint, pearlescent paint and metallic paint based on its texture. Among them, metallic paint has a better effect on shielding micropores than ordinary paint and pearlescent paint due to its higher reflectivity to ambient light.

[0077] Color paint, such as car body paint color, can be defined by the HSV (Hue, Saturation, Value) system. The values ​​of H and S can be customized. The higher the value of V (Value), the lower the value of D / L (the ratio of the aperture of the light-transmitting hole 75 to the center distance between two adjacent light-transmitting holes 75) to ensure the invisibility of the micropores.

[0078] In this embodiment, the numerical relationship between the ratio of the aperture of the light transmission hole 75 to the center distance between two adjacent light transmission holes 75 and the texture and color brightness of different paint surfaces is as follows:

[0079] The ratio of the aperture of the light-transmitting hole to the center distance between two adjacent light-transmitting holes satisfies the following formula:

[0080] Among them, D is the aperture, L is the center distance between two adjacent light-transmitting holes, V is the brightness of the paint layer of the cover plate, a is a constant greater than 0 and less than 1, and the value of a is determined according to the type of the paint layer of the cover plate.

[0081] For example, when the body paint color of the cover plate 70 is ordinary paint or pearlescent paint, the value of a is 0.3, and the ratio of the aperture of the light-transmitting hole 75 to the center distance between two adjacent light-transmitting holes 75 satisfies the following formula:

[0082] Wherein, D is the aperture of the light-transmitting hole 75 , L is the center distance between two adjacent light-transmitting holes 75 , and V is the brightness of the color paint layer 73 of the cover plate 70 .

[0083] When the body paint color of the cover plate 70 is metallic paint, the value of a is 0.4, and the ratio of the aperture of the light-transmitting hole 75 to the center distance between two adjacent light-transmitting holes 75 satisfies the following formula:

[0084] Wherein, D is the aperture of the light-transmitting hole 75 , L is the center distance between two adjacent light-transmitting holes 75 , and V is the brightness of the color paint layer 73 of the cover plate 70 .

[0085] The relationship between the aperture, center distance L, shape of the light-transmitting holes 75 and the arrangement of the plurality of light-transmitting holes 75 and the brightness of the paint layer 73 can be further summarized as the ratio of the area of ​​the cover plate 70 occupied by the light-transmitting holes 75 per unit area.

[0086] In this embodiment, the numerical relationship between the area ratio S of the plurality of light-transmitting holes 75 on the cover plate 70 and the different paint surface textures and color brightness is as follows:

[0087] The area ratio S of the plurality of light-transmitting holes on the cover plate satisfies the following formula:

[0088] Wherein, V is the brightness of the paint layer of the cover plate, b is greater than 7*10 -5 And less than 9*10 -5 , c is a constant greater than 0 and less than 0.1, d is a constant greater than 5 and less than 15, and the values ​​of b, c and d are determined according to the type of the color paint layer of the cover plate.

[0089] When the color paint layer 73 of the cover plate 70 is ordinary paint or pearlescent paint, b can be set to 7.7*10 -5 , c can be set to 0.044, d can be set to 7.044, and the area ratio S of the plurality of light-transmitting holes 75 on the cover plate 70 satisfies the following formula:

[0090] Wherein, the V is the brightness of the paint layer 73 of the cover plate 70 .

[0091] When the color paint layer 73 of the cover plate 70 is metallic paint, b can be set to 4.48*10 -5 , c can be set to 0.0645, d can be set to 12.62, and the area ratio S of the plurality of light-transmitting holes 75 on the cover plate 70 satisfies the following formula: S≤8.48*10 -5 *V 2 -0.0645*V+12.62

[0092] Wherein, the V is the brightness of the paint layer 73 of the cover plate 70 .

[0093] The above is merely a schematic illustration of the relationship between the brightness of different color paint layers 73 and the setting of the light-transmitting holes 75 to ensure that the visibility of the light-transmitting holes 75 is low. The present application is not limited to this.

[0094] Furthermore, the light output unit may include an optical module, which may include multiple light sources 10 and a silicone lens 20 and a light guide 30 sequentially arranged on the light output side of the light source 10. The light guide 30 is provided with multiple light guide channels 31, each light guide channel 31 corresponding to at least one light source 10. The silicone lens 20 is used to converge the light beam so that the light emitted by each light source 10 is incident on its corresponding light guide channel 31. The light guide channel 31 is used to collect the light from the corresponding light source 10 and guide it to the cover plate 70.

[0095] It should be noted that the optical component 60 in Figures 11 and 12 includes a light guide 30 and a silicone lens 20. In addition, the optical module can also include a light distribution lens 40 and a circuit board 50. Multiple light sources 10 are electrically connected to the circuit board 50, and the light source 10 can be plastic-encapsulated on the circuit board 50 through the silicone lens 20.

[0096] The light guide 30 may include a plurality of light isolation brackets 32 , and two adjacent light isolation brackets 32 together form a light guide channel 31 .

[0097] Furthermore, the light source 10 of the optical module is aligned with the light transmission holes 75, that is, the light source 10 of the optical module is arranged in the same arrangement as the light transmission holes 75, so that the light source 10 can transmit light through the light transmission holes 75. In some specific implementations, the optical module and the cover plate 70 can be provided with an alignment structure. When the optical module and the cover plate 70 are connected via the alignment structure, the light source 10 of the optical module is aligned with the light transmission holes 75.

[0098] In some specific implementations, the opening shape of the light-isolating bracket 32 ​​is identical to the cross-sectional shape of the light-transmitting aperture 75. That is, when the light source 10 of the optical module is aligned with the light-transmitting aperture 75, the opening of the light-isolating bracket 32 ​​can overlap with the light-transmitting aperture 75, thereby improving the utilization rate of the light source emitting light from the opening of the light-isolating bracket 32. In some variations, the projection of the opening of the light-isolating bracket 32 ​​overlaps the projection of the light-transmitting aperture 75. That is, when the light source 10 of the optical module is aligned with the light-isolating bracket 32, the opening area of ​​the light-isolating bracket 32 ​​is larger than the opening area of ​​the light-transmitting aperture 75, thereby preventing the dark area caused by the light-isolating bracket 32 ​​from being visible through the light-transmitting aperture 75.

[0099] It should be noted that the multiple light sources 10, silicone lens 20, light guide 30 and light guide channel 31, light distribution mirror 40 and circuit board 50 can all be referred to as described below, and the same parts will not be repeated here in this application.

[0100] The present application adds a silicone lens 20 between the light-emitting side of the light source 10 and the light-entering side of the light guide 30. In this way, the light emitted by the light source 10 can be converged and focused, so that almost all of the light enters the light-guiding channel 31 of the light guide 30. In this way, the brightness of a single display pixel can be increased by 200% compared to before the silicone lens 20 was added, thereby effectively solving the problem in the prior art that the display pixels cannot achieve high-brightness and uniform lighting of the low-power light source 10 due to the influence of heat resistance (the low-power light source 10 can only achieve high-brightness lighting by reducing the distance between the light sources 10, but reducing the distance will cause heat resistance to affect). In addition, the silicone lens 20 added in the present application is light in weight and has a small space requirement. Therefore, compared with the method of increasing the brightness of the display pixel by increasing the power of the light source 10, the cost of the setting method of the present application can be reduced by about 50%. The lighting system device provided in the present application can also achieve high-brightness and uniform lighting of the low-power light source 10.

[0101] Another aspect of the present invention provides an optical module, as shown in FIG11 . The optical module includes multiple light sources 10, a silicone lens 20, and a light guide 30, sequentially disposed on the light-emitting side of each light source 10. The light guide 30 is provided with multiple light-guiding channels 31. Each light-guiding channel 31 corresponds to at least one light source 10. The silicone lens 20 is configured to converge the light beam so that the light emitted by each light source 10 is incident on its corresponding light-guiding channel 31. The light-guiding channel 31 is configured to collect the light from the corresponding light source 10 and direct it for output. This optical module can address the existing problem of low-cost, low-power LEDs, which have difficulty achieving high-brightness and uniform lighting.

[0102] The light source 10 may be an LED light source, and this application does not limit the type of light source 10. The arrangement of the multiple light sources 10 is not limited in this application. The multiple light sources 10 may be arranged in a predetermined arrangement, such as a matrix arrangement, a staggered arrangement, etc. Each light source 10 may be an RBG color-modulating LED chip, which can display different colors through driving control.

[0103] The silicone lens 20 is arranged on the light-emitting side of the light source 10 , and is used to converge the light emitted by the light source 10 so that the light emitted by the light source 10 is focused within a certain range, so that the focused light can be directed to enter the light guide channel 31 of the light guide member 30 .

[0104] A plurality of light guide channels 31 are provided on the light guide member 30, as shown in FIG11. Generally, the plurality of light guide channels 31 correspond to the plurality of light sources 10, that is, the plurality of light sources 10 are arranged in a preset arrangement, and accordingly, the plurality of light guide channels 31 are also arranged in a preset arrangement to form the same shape.

[0105] In addition, it should be noted that the multiple light guide channels 31 can correspond one-to-one with the multiple light sources 10, but this is not limited to a one-to-one correspondence. In this embodiment, it is sufficient to ensure that each light guide channel 31 is equipped with at least one light source 10. Of course, in some embodiments, one light guide channel 31 can correspond to one light source 10; in other embodiments, one light guide channel 31 can correspond to more than one light source 10.

[0106] Each light-guiding channel 31 is used to collect and guide the light emitted by its corresponding light source 10 for output. When each light-guiding channel 31 corresponds to multiple light sources 10, on the one hand, the brightness value of the luminous pixel can be improved, and on the other hand, the luminous pixel can have richer color performance by emitting light of different colors through multiple light sources 10.

[0107] Furthermore, in this embodiment, the different light sources 10 can be independently controlled. Specifically, each light source 10 can independently control the brightness and color of its light, allowing the brightness and color of each light pixel to be varied. This allows for pixelated interactive signals to surrounding traffic participants while still functioning as a traditional signal light. This allows automotive lighting, such as signal lights, to present different visual effects based on specific needs, enhancing the user experience.

[0108] Optionally, the inner wall of the light-guiding channel 31 can be designed as a total reflection surface. In this way, the light passing through the light-guiding channel 31 can be totally reflected and then completely output, thereby improving the utilization rate of the light. The total reflection surface can be achieved by coating the inner wall of the light-guiding channel 31 with a reflective coating, etc. This application does not limit the method for obtaining the total reflection surface, and those skilled in the art can select an appropriate method.

[0109] In summary, the present application provides an optical module, comprising a plurality of light sources 10, and a silicone lens 20 and a light guide 30 sequentially arranged on the light emitting side of the light source 10; a plurality of light guide channels 31 are provided on the light guide 30; each light guide channel 31 corresponds to at least one light source 10, and the silicone lens 20 is used to converge the light beam so that the light emitted by each light source 10 is incident on its corresponding light guide channel 31, and the light guide channel 31 is used to collect the light of the corresponding light source 10 and guide it for output. The present application adds a silicone lens 20 between the light-emitting side of the light source 10 and the light-entering side of the light guide 30. In this way, the light emitted by the light source 10 can be converged and focused, so that almost all of the light enters the light-guiding channel 31 of the light guide 30. In this way, the brightness of a single display pixel can be increased by 200% compared to before the silicone lens 20 is added, thereby effectively solving the problem in the prior art that the display pixels cannot achieve high-brightness and uniform lighting of the low-power light source 10 due to the influence of heat resistance (the low-power light source 10 can only achieve high-brightness lighting by reducing the spacing between the light sources 10, but reducing the spacing will cause heat resistance to occur). In addition, the silicone lens 20 added in the present application is light in weight and has a small space requirement. Therefore, compared with the method of increasing the brightness of the display pixel by increasing the power of the light source 10, the cost of the setting method of the present application can be reduced by about 50%. Therefore, the present application can achieve high-brightness and uniform lighting of the low-power light source 10.

[0110] Continuing to refer to FIG. 11 , optionally, the light guide member 30 includes a plurality of light isolation brackets 32 , and two adjacent light isolation brackets 32 together form a light guide channel 31 .

[0111] In this embodiment, the area of ​​the light entrance of the light guide channel 31 may be larger than the area of ​​the light exit, as shown in FIG11 . In this way, the light is output in a convergent shape, which can improve the overall brightness of the display pixel.

[0112] Optionally, the optical module further includes a photometric mirror 40 disposed on the light-emitting side of the light-guiding channel 31 , and the photometric mirror 40 is connected to a plurality of light-isolating brackets 32 ; the light emitted from the light-guiding channel 31 passes through the photometric mirror 40 and is then output.

[0113] In this embodiment, the light distribution mirror 40 is a transparent optical element. For example, the light distribution mirror 40 can be made of PC (polycarbonate) or PMMA (polymethacrylate), both of which have high light transmittance and are easy to shape during manufacturing, and can well meet the styling requirements of vehicle-mounted lamps, such as signal lights.

[0114] In this embodiment, the light distribution mirror 40 and the light guide 30 are connected as one body. Thus, the light distribution mirror 40 can be used as a support for a plurality of light isolation brackets 32 , thereby saving materials.

[0115] To facilitate the control of multiple light sources 10 , in this embodiment, optionally, the optical module further includes a circuit board 50 , multiple light sources 10 are electrically connected to the circuit board 50 , and the light sources 10 are plastic-sealed on the circuit board 50 through a silicone lens 20 .

[0116] The present application plastic-seales the silicone lens 20 on the circuit board 50 . Thus, no other mounting structure is required when assembling the silicone lens 20 , thereby reducing costs and simplifying assembly steps.

[0117] Optionally, the distance between the optical center axes of two adjacent light sources 10 is between 4 mm and 20 mm. For example, the distance between the optical center axes of two adjacent light sources 10 can be 4 mm, 5 mm, 8 mm, 10 mm, 15 mm, or 20 mm.

[0118] In addition, optionally, the spacing between the optical center axes of any two adjacent light-guiding channels 31 may be the same, but is not limited thereto. In some implementable embodiments, the spacing between the optical center axes of at least two adjacent light-guiding channels 31 may be different (in short, the spacing between the optical center axes of at least one set of two adjacent light-guiding channels 31 is different from the spacing between the optical center axes of at least another set of two adjacent light-guiding channels 31). It should be noted that the optical center axis of the light source 10 refers to the geometric center axis of the light source 10.

[0119] Please refer to Figure 12. Optionally, the silicone lens 20 includes a cylindrical first part surrounding the light source 10 and a hemispherical second part covering the light source 10. The height of the first part and the second part along the first direction is between 2.5 mm and 4 mm, and the diameter of the second part is between 3 mm and 4 mm. The first direction is the arrangement direction of the light source and the silicone lens 20.

[0120] The first portion includes a portion encapsulated on the circuit board 50 and a portion below the upper surface of the light source 10. The height f of the first and second portions along the first direction, and the diameter e of the second portion can be seen in FIG12 .

[0121] As shown in FIG12 , point O is the optical center of the light source 10 , point A is the intersection of the light of the half-decay angle of the light source 10 incident on the surface of the silicone lens 20 , and point B is the point where the light is incident on the opening of the light-isolating bracket 32 ​​.

[0122] It is known that the distance from the light-emitting surface of the light-isolating bracket 32 ​​to point O is h, the width from the widest opening of the light-isolating bracket 32 ​​to the optical center axis of the light source 10 is d, the OA emergent light is the emergent light at the half-decay angle of the light source 10, generally the unilateral half-decay angle (i.e. ∠COA) of the light source 10 is 60 degrees, the vertical distance from point A to point O is a, the horizontal distance from point A to point O is r, the horizontal distance from point A to point B is b, the vertical distance from point A to point B is c, the refractive index of the silicone lens 20 is n, θ is the angle between the normal at the half-decay angle and the horizontal line at the half-decay angle, β is the angle between the emergent light at the half-decay angle and the normal at the half-decay angle, and α is the angle between the OA emergent light and the normal at the half-decay angle. From the above known conditions, we can obtain: a=r×tan30°, b=dr, c=ha=hr×tan30°, n×sinα=1×sinβ, α+60°+90°+θ=180°, tan(β+θ)=c / b;

[0123] [Corrected 21.09.2023 according to Rule 91] The above equation can be used to obtain the following formula: tan(β+θ)=(hr×tan30°) / (dr); n×sin(30°-θ)=sinβ.

[0124] In this way, the parameters of the silicone lens 20 and the light guide channel 31 can be adjusted using the above formula.

[0125] Optionally, in this embodiment, the curvature of the silicone lens 20 at the half-angle of the light source 10 is 90°+θ, where θ is the angle between the normal at the half-angle and the horizontal line at the half-angle. The curvature of the silicone lens 20 within the entire ∠COA range can be appropriately adjusted based on the desired light distribution, thereby achieving a brighter output at the opening of the light-isolating bracket 32. Of course, the curvature of the silicone lens 20 in this application is not limited to the curvature calculated above; other curvatures that appropriately adjust the light distribution are also applicable.

[0126] Optionally, the opening width of the light guide channel 31 is between 4 mm and 20 mm. For example, the opening width of the light guide channel 31 can be 4 mm, 5 mm, 10 mm, 15 mm or 20 mm.

[0127] The ratio of the opening width of the light guiding channel 31 to the depth of the light guiding channel 31 is between 1 and 2. For example, the ratio of the opening width of the light guiding channel 31 to the depth of the light guiding channel 31 can be 1, 1.5 or 2.

[0128] Another aspect of the present application provides an optical control method for an optical module. The optical control method for an optical module is applied to the above-mentioned optical module, and the optical control method includes:

[0129] 1) When the ambient illumination is less than a preset illumination, the driving currents of the plurality of light sources 10 are controlled to light up at their respective predetermined driving currents;

[0130] 2) When the ambient illumination is greater than or equal to the preset illumination, the driving current of some light sources 10 is reduced.

[0131] It should be noted that the optical control method of the optical module provided in this application is applied to the above-mentioned optical module. The optical control method includes: controlling the magnitude of the driving current of the plurality of light sources 10 according to the ambient illumination.

[0132] Specifically, controlling the magnitude of the driving current of the plurality of light sources 10 according to the ambient illumination can be achieved in the following manner:

[0133] 1) When the ambient illumination is less than a preset illumination, the driving currents of the multiple light sources 10 are controlled to illuminate at their respective predetermined driving currents. That is, when the ambient illumination is low, the driving currents of the multiple light sources 10 can be controlled to illuminate at their respective predetermined currents. This can achieve a high pixel resolution effect even when the ambient illumination is low.

[0134] 2) When the ambient illumination is greater than or equal to the preset illumination, the driving current of some light sources 10 is reduced and the driving current of the remaining light sources 10 is increased. In other words, when the ambient illumination is high, the driving current of some light sources 10 can be reduced and the predetermined current of the remaining light sources 10 can be increased. In this way, the effect of high brightness pixels and high recognition can be achieved when the ambient illumination is high.

[0135] For ease of understanding, it is assumed that the optical module includes a total of n light sources 10, wherein the predetermined driving currents of the n light sources 10 are I1, I2, ..., I n The maximum driving current allowed for a single light source 10 is I max At this time, if the ambient illumination is less than the preset illumination, each single light source 10 in the n light sources 10 is driven by its own predetermined driving current (I1, I2, ... I n if the ambient illumination is greater than or equal to the preset illumination, the predetermined driving current of the n light sources 10 can be reduced, and the predetermined driving current of the remaining light sources 10 can be increased.

[0136] Assume that the predetermined driving current of m light sources 10 is reduced, wherein the reduction amount of the predetermined driving current of each light source 10 in the m light sources 10 is Δ1, Δ2, ... Δ m , then the average increase in the predetermined driving current of the remaining nm LEDs is: ΔI x =(Δ1+Δ2+.....+Δ m ) / (nm)

[0137] The increased driving current I of the i-th light source 10 ix For: I ix =ΔI x +I i max

[0138] Of course, the above-mentioned increase and decrease methods are only examples, and this application is not limited to the above-mentioned theoretical calculation values. The increase in the above-mentioned predetermined driving current can be appropriately adjusted according to the distribution and heat resistance of the light source 10, and the increase and / or decrease in the driving current of each light source 10 can be adjusted to different values ​​as needed.

[0139] The present application provides an optical control method for an optical module, which can adjust the predetermined driving current of the light source 10 under different illuminations, thereby achieving high pixel resolution when the ambient illumination is low, and achieving high pixel brightness and high recognition when the ambient illumination is high, thereby achieving functional optimization without increasing hardware costs.

[0140] Optionally, the preset illuminance may be 1000 lux. Of course, the preset illuminance value is only an example and is not intended to limit the present application. Those skilled in the art may adjust the specific value of the preset illuminance according to different requirements in different application scenarios.

[0141] Optionally, the above step of reducing the driving current of some light sources 10 when the ambient illumination is greater than or equal to the preset illumination may further include the following method:

[0142] Reducing the driving current of some light sources 10 to 0; and / or

[0143] The driving current of the remaining light sources 10 is increased.

[0144] That is, at least one of a method of reducing the driving current of some light sources 10 to 0 and a method of increasing the driving current of the remaining light sources 10 may be adopted.

[0145] Optionally, the increase in the driving current of the remaining light sources 10 is positively correlated with the decrease in the driving current of the portion of the light sources 10. That is, the increase in the driving current of the remaining light sources 10 may vary with the decrease in the driving current of the portion of the light sources 10. For example, when the decrease in the driving current of the portion of the light sources 10 increases, the increase in the driving current of the remaining light sources 10 may also increase accordingly; and when the decrease in the driving current of the portion of the light sources 10 decreases, the increase in the driving current of the remaining light sources 10 may also decrease accordingly.

[0146] The present application also provides a vehicle exterior, including the lighting system device described above. The vehicle exterior may be, for example, a grille, a bumper surface, an exterior door panel, etc., but the present application is not limited thereto. ​

[0147] The present application also provides a vehicle interior, including the lighting system device described above. The vehicle interior can be, for example, a vehicle interior lighting lamp, an ambient light, etc., but the present application is not limited thereto.

[0148] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
