[0002] The lighting system device can be combined with exterior bumpers, exterior grilles, exterior door panels and other components. At present, the global automobile is accelerating towards electrification and intelligence, and the automobile styling design trend has the following obvious trends: the front grille becomes a closed design or is directly cancelled, and the height of the lamp becomes narrower and longer. On the one hand, there is the demand for lighting atmosphere and V2X interaction of smart electric vehicles, but on the other hand, the styling trend reduces the area of ​​​​luminous lamps, forming a contradiction.

[0003] The principle of existing lighting system devices is that light is emitted through translucent paint, semi-transparent materials or ink layers, and the light will change with the original color of the above medium.

[0035] The present application provides a lighting system device, a light emitting unit and a cover plate, wherein the cover plate is used for the light emitting unit to emit light, 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 part of the second light-transmitting holes are connected to at least part of the first light-transmitting holes, and the correspondingly connected first light-transmitting holes and the 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 so 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 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 that without the first light-transmitting hole and the second light-transmitting hole, thereby hiding the light emitting unit behind the cover plate.

In addition, the silicone lens added in the present application is light in weight and requires little space, so compared with the method of increasing the brightness of the display pixel by increasing the power of the light source, the cost of the arrangement method of the present application can be reduced by about 50%. Therefore, the present application can achieve high brightness and uniform lighting of a low-power light source. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The present application provides a new lighting system device (non-traditional lamp) that can emit light in the grille, bumper surface, exterior door panel light area or other locations of the vehicle (such as vehicle interior lighting, ambient lighting, etc.), which can meet the styling requirements and achieve light display, while the color of the light is not affected by the color of the cover itself. The specific structure of the new lighting system device provided by the present application will be described in detail below.

[0052] In one aspect of the present application, a lighting system device is provided. Figure 1 and Figure 2 The lighting system device includes a light emitting unit and a cover plate 70. The cover plate 70 is used for the optical module to emit 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 emitting unit, the primer layer 72 is provided with a plurality of first light-transmitting holes 721, the color paint layer 73 is provided with a plurality of second light-transmitting holes 731, at least part of the second light-transmitting holes 731 is connected with at least part of the first light-transmitting holes 721, and the correspondingly connected first light-transmitting holes 721 and the second light-transmitting holes 731 jointly form a light-transmitting hole position 75.

[0053] The present application sets a plurality of first light-transmitting holes 721 on the primer layer 72, sets 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, so that the color paint layer 73 and the primer layer 72 can have a plurality of light-transmitting hole positions 75, so that 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.

[0054] 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 enable the light emitted by the light emitting unit to display the color of the light unit itself through the first light-transmitting hole 721 and the second light-transmitting hole 731 when the light emitting unit emits light, 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, so that the light emitting unit behind the cover plate 70 can be hidden.

[0055] The light emitting unit at least includes 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 thereto. The light emitting unit may include an optical module, and the optical module may have the same structure as an optical module used for car lights, interior lights, and ambient lights, but the present application is not limited thereto. 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.

[0056] 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.

[0057] In some embodiments, when the light emitting unit has multiple light sources, the multiple light sources are arranged in alignment with the light transmission hole position 75 formed by the first light transmission hole 721 and the second light transmission hole 731. However, the present application is not limited thereto, and the multiple light sources may also be staggered with the light transmission hole position 75 formed by the first light transmission hole 721 and the second light transmission hole 731.

[0058] In some embodiments, when the light emitting unit has multiple light sources, the light sources 10 of the light emitting unit can be controlled individually to display different pixel patterns through the first light transmission hole 721 and the second light transmission hole 731. However, the present application is not limited thereto, and the light sources 10 of the light emitting unit can also be controlled uniformly.

[0059] Optionally, the first light-transmitting hole 721 and the second light-transmitting hole 731 are both formed by laser process.

[0060] 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 and 400 um.

[0061] 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 100-1000 um.

[0062] The laser process uses punching processing to make the cover plate 70 have light transmission ability at the punched area. The larger the area ratio of the hole per unit area, the higher the transmittance, and the easier it is to identify the hole in the static appearance; conversely, the smaller the area ratio of the hole per unit area, the lower the transmittance, and the static appearance is not easy to identify the hole, which can be consistent with the non-punched area.

[0063] 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 .

[0064] 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.

[0065] Please refer to Figure 3 , the ratio of the aperture of the light-transmitting hole 75 to the center distance between two adjacent light-transmitting holes 75 is greater than or equal to 0.2. At this time, the transmittance of the cover plate 70 is high, the light-transmitting hole 75 can be clearly identified during the day, and the light-transmitting hole 75 can be clearly observed from the static appearance. Figure 3In the embodiment, the aperture of the light-transmitting hole 75 is 40um, the center distance between two adjacent light-transmitting holes 75 (hereinafter referred to as center distance) L=200um, and D / L=0.2. Therefore, in some preferred embodiments, the ratio of the aperture of the light-transmitting hole 75 to the 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 hole 75 can be clearly observed from the static appearance.

[0066] Please refer to Figure 4 Optionally, when the ratio of the aperture of the light-transmitting hole 75 to the center distance of two adjacent light-transmitting holes 75 is less than or equal to 0.2, for example, the ratio of the aperture of the light-transmitting hole 75 to the center distance of two adjacent light-transmitting holes 75 is less than or equal to 0.1. In this case, the transmittance of the cover plate 70 is low, the light-transmitting hole 75 can only be identified at night, the light-transmitting hole 75 cannot be observed in the static appearance, and the static appearance is excellent. Figure 4 In the figure, the aperture of the light-transmitting hole 75 is 20 um, the center distance L=200 um, and D / L=0.1.

[0067] like Figure 5 and Figure 6 As shown, when the center distance L changes (from 200um to 100um), maintaining the numerical relationship between the aperture of the light-transmitting hole 75 and the center distance L can achieve equivalent transmittance and static appearance. Figure 5 The aperture of the middle light transmission hole 75 is 20um, and the center distance L = 100um; Figure 6 In the figure, the aperture of the light-transmitting hole 75 is 10 um, and the center distance L is 100 um.

[0068] Please refer to Figure 7 and Figure 8 The light-transmitting hole 75 is not limited to a circular shape, but may also be a square or any other shape. Fig. 9 and Fig.10 The arrangement of the plurality of light-transmitting holes 75 is not limited to a regular matrix arrangement, and may also be an irregular arrangement.

[0069] In some embodiments of the present application, the regular arrangement or irregular arrangement of multiple light-transmitting holes 75 can make multiple light-transmitting holes 75 display pixelated graphics and animations. The shape of the light-transmitting holes 75 can be matched with the arrangement method to improve the playback effect of pixelated graphics and animations. In some embodiments, the light-transmitting holes 75 can be, for example, a triangle, and the multiple light-transmitting holes 75 can be arranged in a parallelogram manner, and the two sides of the arrangement parallelogram are respectively parallel to the two sides of the triangle of the light-transmitting holes 75, so that the corresponding row and column pixels can be presented. At the same time, since the row and column pixels are not vertical, the pixels of adjacent rows are staggered or the pixels of adjacent columns are staggered to improve the display continuity of the oblique lines in the graphics and increase the fun of the animation display. Further, the triangular shape of adjacent light-transmitting holes 75 can be inverted, that is, arranged in a manner of an equilateral triangle of an adjacent light-transmitting hole 75 and an inverted triangle of an adjacent light-transmitting hole 75, further reducing the jagged display of the oblique lines in the graphics and improving the playback effect of pixelated graphics and animations. In some variations, the shapes of the light-transmitting holes 75 may also be different from each other.

[0070] In some embodiments of the present application, each light-transmitting hole 75 can also be composed of a plurality of 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-holes is relatively small, the transmittance of each light-transmitting sub-hole is relatively small, thereby reducing the visibility of the light-transmitting hole 75 when the optical module is not emitting light.

[0071] Furthermore, the relationship between the aperture of the light-transmitting holes 75, the center distance L, the shape of the light-transmitting holes 75, and the 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.

[0072] The cover plate 70 has light-transmitting holes 75 of unlimited shapes arranged in a preset arrangement 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:

[0073] The first case: the area of ​​the plurality of light-transmitting holes 75 on the cover plate 70 accounts for less than or equal to 0.79% (i.e., the area occupied by the light-transmitting holes 75 per unit area is ≤ 0.79%). In this case, the transmittance can only be identified at night, the light-transmitting holes 75 cannot be observed in the static appearance, and the static appearance is excellent.

[0074] 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, the light-transmitting holes 75 can be clearly observed in the static appearance, and the appearance effect is not perfect.

[0075] 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% (ie, 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.

[0076] Therefore, in this embodiment, in order 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%.

[0077] In addition, in actual implementation, the color paint layer 73 can be divided into ordinary paint, pearl paint and metallic paint in terms of texture. Among them, metallic paint has a better effect on micropore shielding than ordinary paint and pearl paint because of its higher reflectivity to ambient light.

[0078] 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) must be to ensure the invisibility of the micropores.

[0079] In this embodiment, the numerical relationship between the aperture of the light-transmitting hole 75 and the center distance between two adjacent light-transmitting holes 75 and the texture and color brightness of different paint surfaces is as follows:

[0080] The ratio of the aperture of the light-transmitting hole to the center distance between two adjacent light-transmitting holes satisfies the following formula:

[0081]

[0082] 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.

[0083] For example, when the body paint color of the cover plate 70 is ordinary paint or pearlescent paint, 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:

[0084]

[0085] 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 .

[0086] When the body paint color of the cover plate 70 is metallic paint, a is set to 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:

[0087]

[0088] 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 .

[0089] The relationship between the aperture, center distance L, shape and arrangement of the 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.

[0090] 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:

[0091] The area ratio S of the plurality of light-transmitting holes on the cover plate satisfies the following formula:

[0092] S≤b*V 2 -c*V+d

[0093] 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 A constant, 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.

[0094] 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 taken as 0.044, d can be taken as 7.044, and the area proportion S of the plurality of light-transmitting holes 75 on the cover plate 70 satisfies the following formula:

[0095] S≤7.7*10 -5 *V 2 -0.044*V+7.044

[0096] Wherein, the V is the brightness of the paint layer 73 of the cover plate 70 .

[0097] When the color paint layer 73 of the cover plate 70 is metallic paint, b can be set to 8.48*10 -5 , c can be taken as 0.0645, d can be taken as 12.62, and the area ratio S of the plurality of light-transmitting holes 75 on the cover plate 70 satisfies the following formula:

[0098] S≤8.48*10 -5 *V 2 -0.0645*V+12.62

[0099] Wherein, the V is the brightness of the paint layer 73 of the cover plate 70 .

[0100] 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, and the present application is not limited thereto.

[0101] Further, the light output unit may include an optical module, and the optical module may include a plurality of 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 a plurality of light guide channels 31, 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 corresponding to the light source 10 and guide it to the cover plate 70.

[0102] Among them, it should be noted that Fig.11 and Fig.12 The optical component 60 includes a light guide 30 and a silicone lens 20. In addition, the optical module may 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-sealed on the circuit board 50 through the silicone lens 20.

[0103] 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 .

[0104] Further, the light source 10 of the optical module and the light transmission hole 75 are arranged in alignment, that is, the light source 10 of the optical module is arranged in the same arrangement as the light transmission hole 75, so that the light source 10 can transmit light from the light transmission hole 75. In some specific implementations, the optical module and the cover plate 70 may be provided with an alignment structure, and when the optical module and the cover plate 70 are connected through the alignment structure, the light source 10 of the optical module and the light transmission hole 75 are aligned.

[0105] In some specific implementations, the opening shape of the light-isolating bracket 32 ​​is the same as the cross-sectional shape of the light-transmitting hole 75, that is, when the light source 10 of the optical module is aligned with the light-transmitting hole 75, the opening of the light-isolating bracket 32 ​​can overlap with the light-transmitting hole 75 to improve the utilization rate of the light source emitting light from the opening of the light-isolating bracket 32. In some variations, the opening projection of the light-isolating bracket 32 ​​covers the projection of the light-transmitting hole 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 hole 75 to avoid seeing the dark area caused by the light-isolating bracket 32 ​​from the light-transmitting hole 75.

[0106] It should be noted that the multiple light sources 10, the silicone lens 20, the light guide 30 and the light guide channel 31, the light distribution lens 40 and the circuit board 50 can all be referred to as described below, and the same parts will not be repeated in this application.

[0107] 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, so that the light emitted by the light source 10 can be converged and concentrated, so that almost all of the light enters the light-guiding channel 31 of the light guide 30, so that the brightness of a single display pixel can be increased by 200% compared with before the silicone lens 20 is added, thereby effectively solving the problem in the prior art that the display pixel cannot be evenly lit with high brightness due to the limitation of heat resistance (the low-power light source 10 can only be lit by reducing the distance between the light sources 10, but reducing the distance will cause heat resistance). 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 even lighting of the low-power light source 10.

[0108] Another aspect of the present application embodiment provides an optical module, please refer to Fig.11 The optical module includes 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; the light guide 30 is provided with a plurality of light guide channels 31; 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 optical module can improve the problem in the prior art that low-cost low-power LEDs are difficult to achieve high-brightness and uniform lighting effects.

[0109] Among them, the light source 10 can be an LED light source, and the present application does not limit the type of the light source 10. The arrangement of the above-mentioned multiple light sources 10 is not limited in the present application, and the multiple light sources 10 can be arranged in a preset arrangement, and the preset arrangement can be a matrix arrangement, a staggered arrangement, etc. Each light source 10 can be an RBG color-adjusting LED chip, which can display different colors through driving control.

[0110] 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 be incident into the light guide channel 31 of the light guide member 30 .

[0111] The light guide member 30 is provided with a plurality of light guide channels 31, such as Fig.11 As shown, 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.

[0112] In addition, it should be noted that the multiple light guide channels 31 can correspond to the multiple light sources 10 one by one, but are not limited to a one-to-one correspondence. In this embodiment, it is only necessary 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 may correspond to one light source 10; in other embodiments, one light guide channel 31 may correspond to more than one light source 10.

[0113] 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 expression by emitting light of different colors by multiple light sources 10.

[0114] In addition, in this embodiment, different light sources 10 can be controlled independently, that is, each light source 10 can control the light brightness and light color independently, so that the light brightness and light color of each light-emitting pixel can be changed, and pixelated interactive signals can be sent to surrounding traffic participants while realizing the traditional signal light function. In this way, automobile lamps, such as signal lights, can present different visual effects according to different needs, which can improve the personalized experience of users.

[0115] Optionally, the inner wall of the light guide channel 31 can be designed as a total reflection surface, so that the light passing through the light guide channel 31 can be totally reflected and then output, thereby improving the utilization rate of the light. The total reflection surface can be achieved by coating a reflective coating on the inner wall of the light guide channel 31, etc. The present application does not limit the method of obtaining the total reflection surface, and those skilled in the art can choose a suitable method.

[0116] 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 which are sequentially arranged on the light emitting side of the light source 10; a plurality of light guide channels 31 are arranged 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 corresponding to the 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, so that the light emitted by the light source 10 can be converged and concentrated, so that almost all of the light enters the light-guiding channel 31 of the light guide 30, so that 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 pixel cannot be evenly lit with high brightness due to the influence of heat resistance (the low-power light source 10 can only be lit by reducing the distance between the light sources 10 to achieve high brightness, but reducing the distance will cause heat resistance). 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 even lighting of the low-power light source 10.

[0117] Please continue 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 .

[0118] 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 thereof. Fig.11 As shown, in this way, the light is output in a convergent shape, which can improve the overall brightness of the display pixels.

[0119] Optionally, the optical module further includes a light distribution mirror 40 disposed on the light output side of the light guide channel 31 , and the light distribution mirror 40 is connected to a plurality of light isolation brackets 32 ; the light emitted from the light guide channel 31 is output after passing through the light distribution mirror 40 .

[0120] 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 (polymethyl methacrylate), 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.

[0121] In this embodiment, the light distribution mirror 40 and the light guide 30 are connected as one body, so that the light distribution mirror 40 can be used as a support for a plurality of light isolation brackets 32, thereby saving materials.

[0122] To facilitate the control of multiple light sources 10 , in this embodiment, optionally, the optical module also includes a circuit board 50 , the 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 .

[0123] The present application seals the silicone lens 20 on the circuit board 50 , so that no other mounting structure is required when assembling the silicone lens 20 , thereby reducing costs and simplifying assembly steps.

[0124] 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 may be 4 mm, 5 mm, 8 mm, 10 mm, 15 mm or 20 mm.

[0125] In addition, optionally, the spacing between the optical center axes of any two adjacent light guide channels 31 may be the same, but is not limited thereto. In some achievable ways, the spacing between the optical center axes of at least two adjacent light guide channels 31 may be different (in short, the spacing between the optical center axes of at least one group of two adjacent light guide channels 31 is different from the spacing between the optical center axes of at least another group of two adjacent light guide 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.

[0126] Please refer to Fig.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.

[0127] The first portion includes a portion encapsulated on the circuit board 50 and a portion located below the upper surface of the light source 10. The height f of the first portion and the second portion along the first direction, and the diameter e of the second portion can be referred to Fig.12 shown.

[0128] like Fig.12 It is known that point O is the optical center of the light source 10 , point A is the intersection point where the light of the half-decay angle of the light source 10 is 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 ​​.

[0129] It is known that the distance from the light-emitting surface of the light-isolating bracket 32 ​​to the 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 emitted light is the emitted light of the light source 10 at the half-decay angle, the unilateral half-decay angle (i.e. ∠COA) of the light source 10 is generally 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 emitted light at the half-decay angle and the normal at the half-decay angle, and α is the angle between the OA emitted light and the normal at the half-decay angle. From the above known conditions, we can get:

[0130] a=r×tan30°, b=dr, c=ha=hr×tan30°, n×sinα=1×sinβ, α+60°+90°+θ=180°, tan(β+θ)=c / b;

[0131] The above equation can be used to obtain the following formula:

[0132] tan(β+θ)=(hr×tan30°) / (dr)n×sin(30°-θ)=sinβ.

[0133] In this way, the parameters of the silicone lens 20 and the light guide channel 31 can be adjusted by the above formula.

[0134] Optionally, in this embodiment, the curvature of the silicone lens 20 at the half-decay angle of the light source 10 is 90°+θ, where θ is the angle between the normal line at the half-decay angle and the horizontal line at the half-decay angle. The curvature of the silicone lens 20 within the entire ∠COA range can be appropriately adjusted according to the required light distribution, so that a brighter output is obtained 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, and other curvatures that make appropriate adjustments to the light distribution are applicable.

[0135] Optionally, the opening width of the light guide channel 31 is between 4 mm and 20 mm. Exemplarily, the opening width of the light guide channel 31 can be 4 mm, 5 mm, 10 mm, 15 mm or 20 mm.

[0136] 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.

[0137] Another aspect of the present application provides an optical control method of an optical module. The optical control method of the optical module is applied to the above optical module. The optical control method includes:

[0138] 1) When the ambient illumination is less than the preset illumination, the driving currents of the plurality of light sources 10 are controlled to light up at their respective preset driving currents;

[0139] 2) When the ambient illumination is greater than or equal to the preset illumination, the driving current of some light sources 10 is reduced.

[0140] It should be noted that the optical control method of the optical module provided in the present application is applied to the above 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.

[0141] 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:

[0142] 1) When the ambient illumination is less than the preset illumination, the driving currents of the multiple light sources 10 are controlled to light up at their respective preset driving currents. That is, when the ambient illumination is low, the driving currents of the multiple light sources 10 can be controlled to light up at their respective preset currents, so that the effect of high pixel resolution can be achieved when the ambient illumination is low.

[0143] 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. That is, when the ambient illumination is high, the driving current of some light sources 10 can be reduced and the preset current of the remaining light sources 10 can be increased, so that the effect of high brightness pixels and high recognition can be achieved when the ambient illumination is high.

[0144] 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 each single light source 10 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 among the n light sources 10 is driven by its own preset driving current (I1, I2, ... I n ) is turned on; if the ambient illumination is greater than or equal to the preset illumination, the predetermined driving current of some of the n light sources 10 can be reduced, and the predetermined driving current of the remaining light sources 10 can be increased.

[0145] 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:

[0146] ΔI x =(Δ1+Δ2+.....+Δ m ) / (nm)

[0147] The increased driving current I of the i-th light source 10 ix for:

[0148] I ix =ΔI x +I i max

[0149] Of course, the above-mentioned increase and decrease methods are only examples, and the present 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.

[0150] 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 the effect of high pixel resolution when the ambient illumination is low, and achieving the effect of high pixel brightness and high recognition when the ambient illumination is high, thereby achieving functional optimization without increasing hardware costs.

[0151] Optionally, the preset illumination may be 1000 lux. Of course, the preset illumination value is only an example and is not a limitation of the present application. In different application scenarios, those skilled in the art may adjust the specific value of the preset illumination according to different requirements.

[0152] 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 also includes the following method:

[0153] Reducing the driving current of some light sources 10 to 0; and / or

[0154] The driving current of the remaining light sources 10 is increased.

[0155] 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.

[0156] ​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 partial light sources 10. That is, the increase in the driving current of the remaining light sources 10 may change with the decrease in the driving current of the partial light sources 10. For example, when the decrease in the driving current of the partial light sources 10 increases, the increase in the driving current of the remaining light sources 10 may also increase accordingly; when the decrease in the driving current of the partial light sources 10 decreases, the increase in the driving current of the remaining light sources 10 may also decrease accordingly.

[0157] The present application also provides a vehicle exterior, including the lighting system device as 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.

[0158] The present application also provides a vehicle interior, including the lighting system device as described above. The vehicle interior can be, for example, a vehicle interior lighting lamp, an atmosphere lamp, etc., but the present application is not limited thereto.

[0159] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
