Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, electrical connections, or mutual communication; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0035] The optical module, headlight and vehicle in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] In the prior art, the vehicle lights are lit as a whole, and the display effect is single, which cannot meet the growing personalized demand for vehicle lights.

[0037] In order to solve the above technical problems, an embodiment of the present application provides an optical module, including a first light source and a first light-guiding component; the first light source is configured to provide light; the first light-guiding component has a first surface, a second surface and a light-entering side surface; in a three-dimensional coordinate system, the first surface and the second surface are sequentially spaced along the X-axis direction, the light-entering side surface is connected between the first surface and the second surface, and the X-axis direction is parallel to the main light-emitting direction of the first light-guiding component; the first surface is provided with a plurality of first dermatoglyphic areas, the second surface is provided with a plurality of second dermatoglyphic areas, and the light-entering side surface is configured to receive the light provided by the first light source; a projection plane λ perpendicular to the X-axis direction is set, and the orthographic projection of the first dermatoglyphic area on the projection plane λ is spaced and / or partially overlapped with the orthographic projection of the second dermatoglyphic area on the projection plane λ. This is explained in detail below.

[0038] See Figure 1-4 The optical module includes a first light source 10 and a first light-guiding component 20; the first light source 10 is configured to provide light; the first light-guiding component 20 has a first surface 21, a second surface 22 and a light-entering side surface 23; in a three-dimensional coordinate system, the first surface 21 and the second surface 22 are spaced apart in sequence along the X-axis direction, the light-entering side surface 23 is connected between the first surface 21 and the second surface 22, and the X-axis direction is parallel to the main light-emitting direction of the first light-guiding component 20; the first surface 21 is provided with a plurality of first dermatoglyphic areas 211 at intervals, and the second surface 22 is provided with a plurality of second dermatoglyphic areas 221 at intervals, and the light-entering side surface 23 is configured to receive the light provided by the first light source 10; a projection plane λ perpendicular to the X-axis direction is set, and the orthographic projection of the first dermatoglyphic area 211 on the projection plane λ is spaced and / or partially overlapped with the orthographic projection of the second dermatoglyphic area 221 on the projection plane λ.

[0039] For the convenience of explanation, in the following embodiments, the first light source 10 is disposed on the top of the first light guide member 20 ( Figure 1 The first light source 10 emits light from the top surface (light incident side surface 23 ) of the first light guide member 20 and enters the interior of the first light guide member 20 .

[0040] Part of the light incident from the top of the first light-guiding component 20 is irradiated on the first surface 21. The light irradiated on the first dermatoglyphic area 211 is diffusely reflected by the dermatoglyphics of the first dermatoglyphic area 211 and then emitted from the second surface 22. The light irradiated on the smooth surface area of ​​the first surface 21 (the area other than the first dermatoglyphic area 211) is totally reflected by the smooth surface area and does not emit from the second surface 22. In other words, the human eye can only observe the light in the area of ​​the first dermatoglyphic area 211, that is, the regional shape of the first dermatoglyphic area 211. Similarly, the light irradiated on the second surface 22 is diffusely reflected by the dermatoglyphics of the second dermatoglyphic area 221 and then emitted from the second surface 22 along the X-axis direction. The light irradiated on the smooth surface area of ​​the second surface 22 is totally reflected by the smooth surface area and does not emit from the second surface 22. The human eye can only observe the light in the area of ​​the second dermatoglyphic area 221.

[0041] At the same time, since the orthographic projections of the first dermatoglyphic area 211 and the second dermatoglyphic area 221 on the projection surface λ are spaced apart, the human eye can observe the spaced dermatoglyphic area patterns (the pattern of the first dermatoglyphic area 211 and the pattern of the second dermatoglyphic area 221), thereby improving the personalization of the optical module lighting. Compared with the conventional technology in which the first light-guiding component 20 is lit as a whole, in the present application, only the first dermatoglyphic area 211 and the second dermatoglyphic area 221 are lit, thereby improving the aesthetics when lit and meeting the requirements for personalized design of vehicle lights.

[0042] In some embodiments, the first dermatoglyphic area 211 and the second dermatoglyphic area 221 may be partially overlapped; or, part of the first dermatoglyphic area 211 (a plurality of independent first dermatoglyphic areas 211 are provided on the first surface 21, and the same applies to the second dermatoglyphic area 221) and part of the second dermatoglyphic area 221 are spaced apart, and the remaining part of the first dermatoglyphic area 211 and the remaining part of the second dermatoglyphic area 221 are partially overlapped; relevant designs can be made according to the personalized lighting requirements of the optical module, but are not limited to this.

[0043] In some embodiments, the area shapes of the first dermatoglyphic area 211 and the second dermatoglyphic area 221 can be a combination of one or more shapes such as a triangle, a square, a circle, a pentagon, etc., and are designed according to actual lighting requirements.

[0044] It is worth mentioning that part of the light emitted by the first light source 10 will be emitted from the bottom of the first light guide component 20, and part of the light after diffuse reflection from the leather grain of the first leather grain area 211 will be reflected to the side of the first surface 21 away from the second surface 22. When the mounting frame 40 (for mounting the first light guide component 20) is set with a high-gloss black material, the light emitted from the first light guide component 20 will be reflected and re-enter the first light guide component 20, thereby improving the utilization rate of the light and avoiding the occurrence of dark areas and other poor lighting effects.

[0045] It should be noted that when light strikes the first and second dermatoglyphic regions 211, 221, due to the structural characteristics of the dermatoglyphic structure, the light is diffusely reflected, meaning that the light can be emitted at multiple angles. Multiple first and second dermatoglyphic regions 211, 221 are provided at intervals. The shapes of the multiple first dermatoglyphic regions 211 on the first surface 21 can be identical or different, depending on the actual lighting requirements. The same applies to the multiple second dermatoglyphic regions 221 on the second surface 22. Furthermore, the first light source 10 can be, for example, a LED mounted on a printed circuit board, and this is not specifically limited here.

[0046] In some embodiments, in the X-axis direction, the distance between the light source and the first dermatoglyphic area 211 is d1, and the distance between the light source and the second dermatoglyphic area 221 is d2, satisfying: d1≠d2.

[0047] When d1≠d2, the propagation distance of the light irradiated to the first dermatoglyphic area 211 (emitted from the first light source 10) is not equal to the propagation distance of the light irradiated to the second dermatoglyphic area 221 (emitted from the first light source 10), that is, the energy of the light received by the first dermatoglyphic area 211 is not equal to the energy of the light received by the second dermatoglyphic area 221. After lighting, the brightness of the first dermatoglyphic area 211 is inconsistent with the brightness of the second dermatoglyphic area 221. That is, after lighting, the optical module presents a light effect of alternating light and dark, and dotted lights (such as Figure 5 As shown in the figure, it improves the personalization and aesthetics of the optical module lighting and can meet the personalized design needs of car lights.

[0048] It should be noted that, taking the light emitted to the first dermatoglyphic area 211 as an example, its propagation distance refers to the distance the light propagates from the first light source 10 to the first dermatoglyphic area 211. The shorter the propagation distance, the higher the energy received by the first dermatoglyphic area 211 and the higher the brightness. The light emitted to the second surface 22 is similar to this and will not be repeated here.

[0049] In some embodiments, the maximum value of the spacing d1 is smaller than the minimum value of the spacing d2, that is, the propagation distance of all light emitted from the first light source 10 to the first dermatoglyphic area 211 is smaller than the propagation distance of all light emitted from the first light source 10 to the second dermatoglyphic area 221, that is, the lighting brightness of the first dermatoglyphic area 211 is higher than the lighting brightness of the second dermatoglyphic area 221.

[0050] It is worth mentioning that in some embodiments, the minimum value of the spacing d1 may be greater than the maximum value of the spacing d2, that is, the lighting brightness of the first dermatoglyphic area 211 is lower than the lighting brightness of the second dermatoglyphic area 221. When observed by the human eye, the optical module still appears to be alternating light and dark.

[0051] In some embodiments, the optical module further includes a bracket 30 configured to mount the first light guide component 20 ; two first light guide components 20 are provided, and the bracket 30 and the two first light guide components 20 are integrally arranged.

[0052] There are two first light guide members 20, that is, there are two first surfaces 21 (such as Figure 2 21a and 21b) and two second surfaces 22 (as shown in FIG. Figure 2 As shown in 22a and 22b, for the sake of easy distinction, the numbers a and b in the figure distinguish the two first light-guiding components 20), that is, there will be two display areas when lit, which can be combined through the shape of the dermatoglyphic area (the first dermatoglyphic area 211 and the second dermatoglyphic area 221), thereby improving the diversity of display.

[0053] The bracket 30 and the two first light guide components 20 are integrally arranged. In this embodiment, they can be formed by two-color injection molding, which is conducive to improving the control of the relative position between the bracket 30 and the two first light guide components 20, improving the processing accuracy, and thus improving the lighting effect of the optical module. The one-piece molding setting avoids the installation steps between multiple parts and improves production efficiency.

[0054] In some embodiments, the optical module further includes a mounting frame 40 , and the first light guide component 20 is mounted on the mounting frame 40 via a bracket 30 . The mounting frame 40 is made of a reflective material.

[0055] The mounting frame 40 is made of reflective material. The light emitted from the first light guide component 20 is reflected to the first light guide component 20 after being irradiated on the mounting frame 40 , which can improve the utilization rate of light and avoid display defects such as dark areas.

[0056] In some embodiments, the optical module further includes a second light guide component 50 and a second light source 60 . The second light source 60 is configured to provide light to the second light guide component 50 . The bracket 30 is provided with a mounting hole 31 , and the second light guide component 50 is accommodated in the mounting hole 31 .

[0057] Only the first dermatoglyphic area 211 and the second dermatoglyphic area 221 on the first light-guiding component 20 are lit. The optical utilization rate of the first light source 10 is not high, and the light loss is large. In some embodiments (for example, when the optical module is used as a position function lamp), the brightness requirements of the regulations cannot be met. By setting the second light-guiding component 50 and the second light source 60, auxiliary lighting can be provided for the first light-guiding component 20, so that the brightness requirements of the regulations can be met when the optical module is lit as a whole. The structure is simple, which can not only meet the regulatory requirements, but also enhance the overall personalization of the optical module.

[0058] It should be noted that the second light-guiding component 50 can be fixed in the mounting hole 31 by ultrasonic welding or other methods, so as to improve the stability of the installation of the second light-guiding component 50 and avoid light leakage between the second light-guiding component 50 and the mounting hole 31; in some embodiments, other connection methods can also be used, not limited to this.

[0059] It is worth mentioning that the second light guide component 50 and the two first light guide components 20 are all arranged on the same bracket 30. The relative position between the second light guide component 50 and the two first light guide components 20 is controlled more accurately, which is conducive to improving the overall lighting effect.

[0060] In some embodiments, the second light source 60 is a lamp bead on a printed circuit board. The lamp bead can emit yellow light and red light. The yellow light can be used as a turn light source, and the red light can be used as a position light source.

[0061] In some embodiments, the optical module also includes a third light-guiding component 70, and the third light-guiding component 70 and the second light-guiding component 50 are arranged in sequence along the X-axis direction. The light emitted by the second light source 60 is adjusted by the third light-guiding component 70 and then emitted to the second light-guiding component 50; the light-emitting surface of the third light-guiding component 70 is provided with a diffusion pattern 71, and the light-incident surface of the second light-guiding component 50 is provided with a convergence pattern 51.

[0062] The light is diffused after passing through the diffusion pattern 71 on the light-emitting surface of the third light-guiding component 70. The diffused light is converged through the convergence pattern 51 on the light-incident surface of the second light-guiding component 50 and enters the second light-guiding component 50, and is finally emitted from the light-emitting surface of the second light-guiding component 50. After the light is diffused, it is beneficial to improve the uniformity of the light output. After the convergence pattern 51 is set, the propagation of light to non-lit areas is reduced, avoiding reducing the luminous flux and lowering the brightness of the light. It can not only ensure the brightness value of the light, but also achieve the effect of uniform light emission (the third light-guiding component 70 and the second light-guiding component 50 emit light as a whole).

[0063] It is worth mentioning that such a setting can reduce the luminous power of the second light source 60, that is, the brightness value of the light can be met by selecting lamp beads with lower power, which reduces energy consumption and the heat generated by the second light source 60 during operation and improves its service life.

[0064] In some embodiments, the second light guide member 50 is provided with leather grains along its circumference in the X-axis direction.

[0065] By providing leather grain on the circumferential side of the second light guide component 50 in the X-axis direction, the internal structure can be shielded and the bright spots of the lamp beads can be weakened, making the lighting effect more uniform.

[0066] On the other hand, the present application also relates to a vehicle lamp, comprising any one of the aforementioned optical modules, the vehicle lamp further comprising a housing 80 and a photometric lens 90 , the photometric lens 90 being covered on the housing 80 to form a receiving space 100 , and the optical module being received in the receiving space 100 .

[0067] On the other hand, the present application also relates to a vehicle comprising the aforementioned vehicle lamp.

[0068] The technical solution provided in the embodiment of the present application is intended to enable the human eye to observe the spaced-apart dermatoglyphic area patterns (the pattern of the first dermatoglyphic area 211 and the pattern of the second dermatoglyphic area 221 ) by setting the orthographic projections of the first dermatoglyphic area 211 and the second dermatoglyphic area 221 at intervals on the projection surface λ, thereby improving the personalization of the optical module lighting. Compared with the traditional technology in which the first light-guiding component 20 is lit as a whole, in the present application, only the first dermatoglyphic area 211 and the second dermatoglyphic area 221 are lit, thereby improving the aesthetics when lit and meeting the personalized design requirements of the vehicle lamps.
