[0002] Currently, the lighting modules used in automotive interiors are usually composed of headlights and thicker light guide plates. Conventional lighting modules require a large color mixing and light mixing distance, which means that a wide blank area needs to be reserved at the light-incident end of the light guide plate, thus failing to achieve a borderless effect.

[0003] The purpose of this application includes, for example, providing a light-emitting module that can shorten the color mixing and light mixing distance, eliminating the need to reserve a wide blank area, thereby achieving a borderless effect.

[0004] The purpose of this application also includes providing an ambient light in which the light-emitting module can shorten the color mixing and light mixing distance, eliminating the need to reserve a wide blank area, thereby achieving a borderless effect.

[0005] The embodiments of this application can be implemented as follows:

[0010] Optionally, the light-uniforming section includes a first light-guiding surface, a second light-guiding surface, and a third light-guiding surface connected in sequence, wherein the first light-guiding surface and the third light-guiding surface are arranged at an angle to each other.

[0011] Optionally, at least one of the light guide surfaces is a planar or curved surface.

[0012] Optionally, the width of the light guide surface is 0.01-2 mm along the arrangement direction of the plurality of light guide surfaces.

[0021] During operation, the light emitted by the light source passes through the light homogenizer placed between the light source and the light guide. At this time, the light homogenizer can shorten the color mixing and light mixing distance of the light-emitting module, so there is no need to reserve a wide blank area at the light-incident end of the light guide. The width of the frame used to block the blank area can also be reduced, so that the light-emitting module can achieve a borderless effect. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0041] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0042] As disclosed in the background section, some existing light-emitting modules used in automotive interiors require a large color mixing and light mixing distance, which necessitates a wide blank area at the light-incident end of the light guide. The width of the border used to cover this blank area is also relatively large, thus preventing the light-emitting module from achieving a borderless effect. Embodiments of this application provide a light-emitting module that at least addresses the aforementioned technical problems.

[0043] Please refer to Figure 1 , Figure 2 The light-emitting module 10 provided in the embodiments of this application includes a light source 100 and a light guide 200 arranged at intervals along the light guiding direction x. A light homogenizer 300 is arranged between the light source 100 and the light guide 200. The light homogenizer 300 can shorten the color mixing and light mixing distance of the light-emitting module 10.

[0044] Light source 100 is used to mount on PCB board 600. Light source 100 can be selected from LEDs, light-emitting diodes, laser light sources, radiation light sources, etc. For some light sources with surface-encapsulated transparent fixing adhesive, such as... Figure 3 , Figure 4 The light source shown can be equipped with a light-diffusing element 300. For some light sources with surface-encapsulated translucent or opaque adhesive, such as... Figure 5 The light source shown, since the translucent or opaque fixing adhesive can achieve a certain degree of light uniformity, does not need to be equipped with a light uniform element 300. In some embodiments, such as Figure 6 As shown, the light source 100 includes a mounting body 110 and a plurality of light-emitting units 120 disposed on the mounting body 110. The plurality of light-emitting units 120 are arranged at intervals. The mounting body 110 is used to be disposed on the PCB board 600.

[0045] The mounting body 110 serves as the mounting base for multiple light-emitting units 120. For example, the mounting body 110 may be a housing or a bracket. Each light-emitting unit 120 can emit light; for example, if the light source 100 is an LED lamp, then the light-emitting unit 120 may be an LED bead. In some other embodiments, the light source 100 may not include the mounting body 110, and the multiple light-emitting units 120 may be directly mounted on the PCB board 600.

[0046] When the light emitted by each light-emitting unit 120 passes through the light-diffusing element 300, the light-diffusing element 300 will increase the diffusion angle of the light, so that the bright area can be basically fully covered in the narrow area at the light-incident end of the light guide 200, that is, the color mixing and light mixing distance of the light-emitting module 10 is shortened.

[0047] The light guide component 200 can be made of PMMA light guide plate, optical grade PC, optical silicone, or light guide film, electrical signal excitation, chemical material excitation, or various light guide media such as fiber light guide, or other light guide structures that can realize light transmission. There are no restrictions on the types of light guide components.

[0048] It should be noted that the light transmission path direction of the light guide 200 is the light guide direction x. The light source 100 and the light guide 200 are spaced apart along the light guide direction x. Multiple light-emitting units 120 of the light source 100 face the light guide 200. The Lambau point light emitted by the multiple light-emitting units 120 passes through the light homogenizer 300 and becomes uniform light before entering the light guide 200, with different light incident and light blocking methods. By setting the light homogenizer 300 between the light source 100 and the light guide 200, during the operation of the light-emitting module 10, the light emitted by the light source 100 passes through the light homogenizer 300 set between the light source 100 and the light guide 200. At this time, the light homogenizer 300 can shorten the color mixing and light mixing distance of the light-emitting module 10, so that there is no need to reserve a wide blank area at the light incident end of the light guide 200. The width of the frame used to block the blank area can also be reduced, so that the light-emitting module 10 can achieve a borderless effect.

[0049] Please see Figure 7 , Figure 8In some embodiments, the light-diffusing element 300 includes a carrier 310 and a light-diffusing part 320 disposed on the carrier 310. The light-diffusing part 320 can shorten the color mixing and light mixing distance of the light-emitting module 10.

[0050] At least one of the two opposing surfaces of the light source 100 and the light guide 200 is an assembly surface. The carrier 310 is disposed on one side of the assembly surface, that is, the carrier 310 is disposed on the assembly surface. Alternatively, the carrier 310 is disposed in the gap between the light source 100 and the light guide 200. In this case, the carrier 310 can be fixed by other structural components.

[0051] The following are examples of where at least one of the two opposing surfaces of the light source 100 and the light guide 200 is an assembly surface: only the surface of the light source 100 facing the light guide 200 is an assembly surface, and the carrier 310 is disposed on one side of the assembly surface; only the surface of the light guide 200 facing the light source 100 is an assembly surface, and the carrier 310 is disposed on one side of the assembly surface; and both opposing surfaces of the light source 100 and the light guide 200 are assembly surfaces, in which case the carrier 310 is disposed on one side of both assembly surfaces.

[0052] When the surface of the light source 100 facing the light guide 200 is the assembly surface, and the carrier 310 is provided on one side of the assembly surface, the light-diffusing part 320 corresponding to the carrier 310 can be provided on the side of the carrier 310 away from the light source 100, or it can be provided on both sides of the carrier 310 along the light guiding direction x; when the surface of the light guide 200 facing the light source 100 is the assembly surface, and the carrier 310 is provided on one side of the assembly surface, the light-diffusing part 320 corresponding to the carrier 310 can be provided on the side of the carrier 310 away from the light guide 200, or it can be provided on both sides of the carrier 310 along the light guiding direction x.

[0053] When the light source 100 includes a mounting body 110 and multiple light-emitting units 120, the surface of the mounting body 110 facing the light guide 200 is the mounting surface, the carrier 310 is disposed on one side of the mounting surface and covers the multiple light-emitting units 120, and the light-diffusing part 320 is disposed on the side of the carrier 310 away from the mounting body 110 or on both sides of the carrier 310.

[0054] In some embodiments, the light-diffusing section 320 includes a plurality of light-guiding surfaces connected in sequence, with at least two of the plurality of light-guiding surfaces arranged at an angle to each other.

[0055] It should be noted that at least two of the multiple light guide surfaces are arranged at an angle, that is, at least two of the multiple light guide surfaces are relatively inclined. By setting multiple light guide surfaces connected in sequence, these multiple light guide surfaces can form a reflective structure. The light emitted by the light source 100 can be reflected when passing through the multiple light guide surfaces, thereby better mixing the light. The angle between the light guide surfaces can be determined according to the actual light mixing effect. For example, the angle between the light guide surfaces can be 60°, 90° or 120°, and there is no limitation thereto.

[0056] In an optional embodiment, the light-diffusing section 320 includes a first light-guiding surface 321, a second light-guiding surface 322, and a third light-guiding surface 323 connected in sequence, with the first light-guiding surface 321 and the third light-guiding surface 323 arranged at an angle to each other.

[0057] It should be noted that when there are three light guide surfaces in the light homogenizing section 320, the light homogenizing section 320 includes a first light guide surface 321, a second light guide surface 322 and a third light guide surface 323 connected in sequence, and the first light guide surface 321 and the third light guide surface 323 are inclined relative to each other.

[0058] For example, the first light guide surface 321 and the second light guide surface 322 are smoothly connected, the second light guide surface 322 and the third light guide surface 323 are smoothly connected, and the first light guide surface 321 and the third light guide surface 323 are relatively inclined; or, the first light guide surface 321 and the second light guide surface 322 are relatively inclined, the second light guide surface 322 and the third light guide surface 323 are relatively inclined, and the first light guide surface 321 and the third light guide surface 323 are relatively inclined.

[0059] It is understandable that the tilt angle between the first light guide surface 321, the second light guide surface 322 and the third light guide surface 323 can be adjusted according to the actual light mixing effect, and there are no restrictions on this.

[0060] In other embodiments, the number of light guiding surfaces in the light homogenizing section 320 is not limited to three, but can be four or more, and there is no limitation on this.

[0061] Furthermore, at least one light guide surface is a planar or curved surface.

[0062] In some embodiments, the multiple light guide surfaces included in the light uniform section 320 may all be planar or all be arc-shaped, or the multiple light guide surfaces may be a combination of planar and arc-shaped surfaces.

[0063] It should be noted that when some light guide surfaces are flat and others are curved, the angle between the curved surface and the flat surface is defined as follows: the plane formed by the two parallel sides of the curved surface along the arrangement direction of the multiple light guide surfaces is arranged at an angle with the flat surface. The angle between the curved surface and other curved surfaces is defined as follows: the two planes formed by the two parallel sides of each of the two curved surfaces along the arrangement direction of the multiple light guide surfaces are arranged at an angle.

[0064] For example, when the light-diffusing section 320 includes a first light-guiding surface 321, a second light-guiding surface 322, and a third light-guiding surface 323 connected in sequence, the first light-guiding surface 321 and the third light-guiding surface 323 are planar, and the second light-guiding surface 322 is an arc-shaped surface; or, the first light-guiding surface 321 and the second light-guiding surface 322 are planar, and the third light-guiding surface 323 is an arc-shaped surface; or, the first light-guiding surface 321, the second light-guiding surface 322, and the third light-guiding surface 323 are all planar or all are arc-shaped surfaces. In some other embodiments, any light-guiding surface may also be a curved surface other than an arc-shaped surface, and this is not limited.

[0065] In some embodiments, the width of the light guide surface is 0.01-2 mm along the arrangement direction of the plurality of light guide surfaces.

[0066] The widths of the multiple light guide surfaces can be unequal, and the width of any one light guide surface can be selected within the range of 0.01-2mm based on the actual working conditions. For example, the width of some of the multiple light guide surfaces may be in the range of 0.01-1mm, while the width of another portion of the multiple light guide surfaces may be in the range of 1-2mm; or, the width of some of the multiple light guide surfaces may be in the range of 0.01-0.8mm, the width of another portion of the multiple light guide surfaces may be in the range of 0.8-1.6mm, and the width of the remaining portion of the multiple light guide surfaces may be in the range of 1.6-2mm.

[0067] For example, when the light-diffusing section 320 includes a first light guide surface 321, a second light guide surface 322, and a third light guide surface 323 connected in sequence, the width of the first light guide surface 321 is in the range of 0.01-0.8 mm, the width of the second light guide surface 322 is in the range of 0.8-1.6 mm, and the width of the third light guide surface 323 is in the range of 1.6-2 mm; or, the width of the first light guide surface 321 is in the range of 0.01-0.8 mm, the width of the second light guide surface 322 is in the range of 1.6-2 mm, and the width of the third light guide surface 323 is in the range of 0.8-1.6 mm; or, the width of the first light guide surface 321 is in the range of 1.6-2 mm, the width of the second light guide surface 322 is in the range of 0.01-0.8 mm, and the width of the third light guide surface 323 is in the range of 0.8-1.6 mm.

[0068] It should be noted that, for the case where the light guide surface is a plane, the width of the light guide surface is the width of the plane along the arrangement direction of the multiple light guide surfaces; for the case where the light guide surface is an arc-shaped surface, the width of the light guide surface is the distance between the two parallel sides of the arc-shaped surface along the arrangement direction of the multiple light guide surfaces.

[0069] In some embodiments, there are multiple light-diffusing sections 320, and the multiple light-diffusing sections 320 are arranged sequentially along the light-emitting direction y.

[0070] When multiple light-diffusing sections 320 are arranged in sequence, a transition surface is connected between the two light guide surfaces that are closest to each other in two adjacent light-diffusing sections 320. Both light guide surfaces are smoothly connected to the transition surface, which can be a plane or an arc-shaped surface.

[0071] It is understandable that, in the case that no transition surface is provided between the two light guide surfaces that are closest to each other in two adjacent light homogenizing sections 320, the two light guide surfaces that are closest to each other in two adjacent light homogenizing sections 320 are directly connected.

[0072] In some embodiments, the light-diffusing portion 320 is formed by the surface of the carrier 310 protruding outward and / or recessing inward.

[0073] The light-diffusing portion 320 is formed by the surface of the carrier 310 protruding outward and / or concave inward, including: only the surface of the carrier 310 protruding outward to form the light-diffusing portion 320, or only the surface of the carrier 310 concave inward to form the light-diffusing portion 320, or a portion of the surface of the carrier 310 protruding outward to form the light-diffusing portion 320, and another portion of the surface of the carrier 310 concave inward to form the light-diffusing portion 320.

[0074] It should be noted that, for the carrier 310 disposed on one side of the mounting surface of the light source 100, the light-diffusing part 320 is formed by the surface of the carrier 310 protruding outward and / or concave inward, wherein the surface of the carrier 310 is the surface of the carrier 310 away from the light source 100 or the two side surfaces of the carrier 310; for the carrier 310 disposed on one side of the mounting surface of the light guide 200, the light-diffusing part 320 is formed by the surface of the carrier 310 protruding outward and / or concave inward, wherein the surface of the carrier 310 is the surface of the carrier 310 away from the light guide 200 or the two side surfaces of the carrier 310.

[0075] Optionally, if only the surface of the light guide 200 facing the light source 100 is an assembly surface, and a carrier 310 is provided on one side of this assembly surface, the light-diffusing part 320 is formed by the surface of the carrier 310 protruding outward; if both surfaces of the light source 100 and the light guide 200 are assembly surfaces, and a carrier 310 is provided on one side of both assembly surfaces, the light-diffusing part 320 on the carrier 310 on the side of the light source 100 can be formed by the surface of the carrier 310 protruding outward, or the surface of the carrier 310 can be formed by the surface of the carrier 310 being recessed inward, and the light-diffusing part 320 on the carrier 310 on the side of the light guide 200 is formed by the surface of the carrier 310 protruding outward.

[0076] When the light-diffusing section 320 includes multiple light-guiding surfaces, if the light-diffusing section 320 is formed by the outward protrusion of the surface of the carrier 310, the multiple light-guiding surfaces include the light-guiding surface with the highest protrusion height and other light-guiding surfaces disposed on both sides of the light-guiding surface, and the light-guiding surfaces on both sides of the light-guiding surface with the highest protrusion height are relatively inclined; and if the light-diffusing section 320 is formed by the inward concavity of the surface of the carrier 310, the multiple light-guiding surfaces include the light-guiding surface with the deepest concavity depth and other light-guiding surfaces disposed on both sides of the light-guiding surface, and the light-guiding surfaces on both sides of the light-guiding surface with the deepest concavity depth are relatively inclined.

[0077] For example, when the light-diffusing section 320 includes a first light-guiding surface 321, a second light-guiding surface 322, and a third light-guiding surface 323 connected in sequence, if the light-diffusing section 320 is formed by the surface of the carrier 310 protruding outward, the second light-guiding surface 322 has the highest protrusion height, and the first light-guiding surface 321 and the third light-guiding surface 323 located on both sides of the second light-guiding surface 322 are relatively inclined; while if the light-diffusing section 320 is formed by the surface of the carrier 310 recessing inward, the second light-guiding surface 322 has the deepest recess depth, and the first light-guiding surface 321 and the third light-guiding surface 323 located on both sides of the second light-guiding surface 322 are relatively inclined.

[0078] In some embodiments, the carrier 310 includes a substrate, and the light-diffusing portion 320 is disposed on the substrate; or, the carrier 310 includes a substrate and a film layer disposed on the substrate, and the light-diffusing portion 320 is disposed on the film layer.

[0079] It should be noted that the substrate can be made of materials such as silicone resin, PC, or scattering particles, and the film layer can be a uniform light film layer or an angle film layer.

[0080] When the carrier 310 includes only a substrate, the light-diffusing part 320 is formed by the surface of the substrate protruding outward or recessing inward, and the portion of the substrate protruding outward or recessing inward includes multiple light-guiding surfaces; when the carrier 310 includes a substrate and a film layer disposed on the substrate, the light-diffusing part 320 is formed by the surface of the film layer protruding outward or recessing inward, and the portion of the film layer protruding outward or recessing inward includes multiple light-guiding surfaces. In this case, the light-diffusing part 320 can be formed on the film layer by etching or other means, and the film can achieve the effect of secondary superposition of light effects by coating on the substrate.

[0081] In some embodiments, the thickness of the light guide 200 in the light emission direction y is 0.5-2.5 mm, wherein the light emission direction y is perpendicular to the light guide direction x.

[0082] It should be noted that the thickness of existing light guide plates is generally above 3.5mm. In this embodiment, a light guide 200 with a thickness of 0.5-2.5mm is selected. At the same time, a miniature light source can be selected for the light source 100, which reduces the space occupied by the light guide 200 in the light emission direction y to a certain extent, making the entire light-emitting module 10 thinner and lighter.

[0083] For example, the thickness of the light guide 200 in the light emission direction y is 0.5mm, 1mm, 1.5mm, 2mm or 2.5mm. It is understood that the thickness of the light guide 200 in the light emission direction y can be selected within the above range and is not limited thereto.

[0084] In some embodiments, the light-emitting module 10 further includes a reflector 400 and a cover 500 spaced apart along the light-emitting direction y, with the light source 100 and the light guide 200 both located between the reflector 400 and the cover 500.

[0085] It should be noted that the arrangement direction of the light source 100 and the light guide 200 is the light guiding direction x, and the arrangement direction of the reflector 400 and the cover 500 is the light emitting direction y. The reflector 400 has a reflective surface 410, which faces the light source 100 and the light guide 200, and plays the role of reflecting light, thus achieving a light uniformity effect to a certain extent. The surface of the light guide 200 facing the reflector 400 can also be provided with some concave and convex microstructures.

[0086] The reflector 400 can be mounted on a fixed object such as a bracket. The reflector 400 itself can be a diaphragm, or the reflector 400 can include a base structure and a reflective surface 410 mounted on the base structure. The reflective surface 410 can be formed on the base structure by means of coating, printing or other methods.

[0087] For the three different arrangements of the light-diffusing element 300, the transmission paths of the light emitted by the light source 100 include the following:

[0088] When only the surface of the light source 100 facing the light guide 200 is the mounting surface, and a light homogenizer 300 is provided on one side of the mounting surface, the light emitted by the light source 100 is refracted when it passes through the light homogenizer 300.

[0089] When only the surface of the light guide 200 facing the light source 100 is the assembly surface, and a light homogenizer 300 is provided on one side of the assembly surface, the light emitted by the light source 100 is refracted when it passes through the light homogenizer 300.

[0090] When both surfaces of the light source 100 and the light guide 200 are assembly surfaces, and a light homogenizer 300 is provided on one side of each of the two assembly surfaces, the light emitted from the light source 100 undergoes a first refraction when it passes through the light homogenizer 300 on one side of the light source 100, and then undergoes a second refraction when it passes through the light homogenizer 300 on one side of the light guide 200.

[0091] It should be noted that when light passes through the light homogenizer 300, it is refracted, which increases the diffusion angle of the light, thus making the coverage area of ​​the light when it enters the light guide 200 larger.

[0092] After the light enters the light guide 200, part of the light is refracted by the light guide 200 and then emitted from the cover 500, while the other part of the light is refracted by the light guide 200 and reflected by the reflector 400 and then emitted from the cover 500.

[0093] The working principle of the light-emitting module 10 provided in the embodiments of this application is as follows: When the light-emitting module 10 is working, the Lambau dot-shaped light emitted by the light source 100 passes through the light-diffusing component 300 disposed between the light source 100 and the light guide 200. At this time, the light-diffusing component 300 can transform the Lambau dot-shaped light into uniform light, and then guide the uniform light into the light guide 200. The light entering the light guide 200 is refracted by the light guide 200 and reflected by the reflector 400, and finally exits through the cover 500. In the entire transmission process of light, the light-diffusing component 300 disposed between the light source 100 and the light guide 200 shortens the color mixing and light mixing distance of the light-emitting module 10, so that there is no need to reserve a wide blank area at the light-incident end of the light guide 200, and the width of the frame used to block the blank area can also be reduced, so that the light-emitting module 10 can achieve a frameless effect.

[0094] The beneficial effects of the light-emitting module 10 provided in the embodiments of this application include at least the following: during the operation of the light-emitting module 10, the light emitted by the light source 100 passes through the light-diffusing component 300 disposed between the light source 100 and the light guide 200. At this time, the light-diffusing component 300 can shorten the color mixing and light mixing distance of the light-emitting module 10, so that there is no need to reserve a wide blank area at the light-incident end of the light guide 200, and the width of the frame used to block the blank area can also be reduced, so that the light-emitting module 10 can achieve a frameless effect; by setting the light-diffusing part 320 to include a plurality of light guide surfaces connected in sequence, the plurality of light guide surfaces can form a reflective structure to better mix the light.

[0095] like Figures 9-11 As shown, multiple light-emitting units 120 arranged at intervals emit light simultaneously. The light emitted by each light-emitting unit 120 is refracted when passing through the light-diffusing element 300, thereby increasing the diffusion angle of the light. When the light-diffusing element 300 is provided only on one side of the light guide 200, the width w of the blank area on the light guide 200 is reduced, and there is basically no phenomenon of bright and dark partitioning in the blank area. When the light-diffusing element 300 is provided on both the side of the light source 100 facing the light guide 200 and the side of the light guide 200 facing the light source 100, the width w of the blank area on the light guide 200 can be further reduced, and the phenomenon of bright and dark partitioning in the blank area is further weakened.

[0096] Furthermore, embodiments of this application also provide an ambient light, including the aforementioned light-emitting module 10. The ambient light also includes structural components for fixing the PCB board 600, light guide 200, cover 500, and reflector 400; these structural components are not limited.

[0097] like Figure 12 As shown, in the scenario where ambient lighting is applied to automobiles, the light-emitting module 10 can be installed on the dashboard or door panel of the car. Of course, it is understood that this ambient lighting can also be applied to other means of transportation such as aircraft and ships, and there are no limitations on this application.

[0098] In summary, this application provides a light-emitting module 10 and an ambient light. The light-emitting module 10 includes a light source 100 and a light guide 200. By providing a light-diffusing element 300 between the light source 100 and the light guide 200, the light-diffusing element 300 can shorten the color mixing and light mixing distance of the light-emitting module 10. Therefore, it is not necessary to reserve a wide blank area at the light-incident end of the light guide 200. The width of the frame used to block the blank area can also be reduced, so that the light-emitting module 10 can achieve a borderless effect.

[0099] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
