For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0035] The optical module, headlights, and vehicle described in this application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0036] In existing technologies, when the entire headlight is lit, the display effect is monotonous and cannot meet the growing demand for personalized headlights.
[0037] To address the aforementioned technical problems, this application provides an optical module including a first light source and a first light guide component. The first light source is configured to provide light. The first light guide component has a first surface, a second surface, and a light-incident side surface. In a three-dimensional coordinate system, the first surface and the second surface are sequentially spaced along the X-axis, and the light-incident side surface connects the first surface and the second surface. The X-axis direction is parallel to the main light-emitting direction of the first light guide component. The first surface is provided with a plurality of first textured areas at intervals, and the second surface is provided with a plurality of second textured areas at intervals. The light-incident side surface is configured to receive the light provided by the first light source. A projection surface λ is defined perpendicular to the X-axis direction, and the orthographic projections of the first textured areas on the projection surface λ and the orthographic projections of the second textured areas on the projection surface λ are spaced apart and / or partially overlap. This will be described in detail below.
[0038] See Figure 1-4 The optical module includes a first light source 10 and a first light guide component 20. The first light source 10 is configured to provide light. The first light guide component 20 has a first surface 21, a second surface 22, and a light-incident surface 23. In a three-dimensional coordinate system, the first surface 21 and the second surface 22 are spaced apart along the X-axis, and the light-incident surface 23 is connected between the first surface 21 and the second surface 22. The X-axis is parallel to the main light-emitting direction of the first light guide component 20. The first surface 21 is provided with a plurality of first texture areas 211 spaced apart, and the second surface 22 is provided with a plurality of second texture areas 221 spaced apart. The light-incident surface 23 is configured to receive the light provided by the first light source 10. A projection surface λ is set perpendicular to the X-axis direction. The orthographic projection of the first texture area 211 on the projection surface λ and the orthographic projection of the second texture area 221 on the projection surface λ are spaced apart and / or partially overlap.
[0039] For ease of explanation, in the following embodiments, the first light source 10 is disposed on the top of the first light guide component 20. Figure 1 (View angle), that is, the light emitted by the first light source 10 enters the interior of the first light guide component 20 from the top surface (light incident side 23) of the first light guide component 20.
[0040] Light rays incident from the top of the first light guide component 20 partially illuminate the first surface 21. Light rays illuminating the first textured area 211 are diffusely reflected by the texture of the first textured area 211 and then directed toward the second surface 22 and exit from the second surface 22. Light rays illuminating the smooth area of the first surface 21 (the area other than the first textured area 211) are totally reflected by the smooth area and do not exit from the second surface 22. That is, the human eye can only observe the light rays in the area of the first textured area 211, which is also the shape of the area of the first textured area 211. Similarly, light rays illuminating the second surface 22 are diffusely reflected by the texture of the second textured area 221 and then exit from the second surface 22 along the X-axis. Light rays illuminating the smooth area of the second surface 22 are totally reflected by the smooth area and do not exit from the second surface 22. The human eye can only observe the light rays in the area of the second textured area 221.
[0041] Meanwhile, since the first textured area 211 and the second textured area 221 are orthogonally projected onto the projection surface λ at intervals, the human eye can observe the textured area patterns (the patterns of the first textured area 211 and the second textured area 221) at intervals, which enhances the personalization of the optical module lighting. Compared with the traditional technology where the first light guide component 20 is lit up as a whole, in this application only the first textured area 211 and the second textured area 221 are lit up, which improves the aesthetics when lit up and can meet the personalized design requirements of vehicle lights.
[0042] In some embodiments, the first textured area 211 and the second textured area 221 may be partially overlapped; or, a portion of the first textured area 211 (a plurality of independent first textured areas 211 are provided on the first surface 21, and the same applies to the second textured area 221) and a portion of the second textured area 221 may be spaced apart, and the remaining portion of the first textured area 211 and the remaining portion of the second textured area 221 may be partially overlapped; the design can be tailored to the individual lighting requirements of the optical module, and is not limited to this.
[0043] In some embodiments, the area shapes of the first textured area 211 and the second textured area 221 can be one or more combinations of shapes such as triangles, squares, circles, and pentagons, and the design can be carried out according to the actual lighting requirements.
[0044] It is worth mentioning that some of the light emitted from the first light source 10 will be emitted from the bottom of the first light guide component 20. After passing through the diffuse reflection of the first texture area 211, some of the light will also be reflected to the side of the first surface 21 away from the second surface 22. When the mounting bracket 40 (used to mount the first light guide component 20) is made of 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, which improves the utilization rate of light and avoids poor lighting effects such as dark areas.
[0045] It should be noted that when light shines on the first textured area 211 and the second textured area 221, due to the structural characteristics of the texture, the light will undergo diffuse reflection, meaning that the light can be emitted at multiple angles. Multiple first textured areas 211 and multiple second textured areas 221 are provided at intervals. The shapes of the multiple first textured areas 211 on the first surface 21 can be the same or different, depending on the actual lighting requirements. The same applies to the multiple second textured areas 221 on the second surface 22. Furthermore, the first light source 10 can be an LED bead or similar device mounted on a printed circuit board; no specific limitation is made here.
[0046] In some embodiments, in the X-axis direction, the distance between the light source and the first texture area 211 is d1, and the distance between the light source and the second texture area 221 is d2, satisfying that: d1≠d2.
[0047] When d1≠d2, the propagation distance of the light rays incident on the first texture area 211 (emitted from the first light source 10) is not equal to the propagation distance of the light rays incident on the second texture area 221 (emitted from the first light source 10). That is, the energy of the light received by the first texture area 211 is not equal to the energy of the light received by the second texture area 221. Therefore, after lighting, the brightness of the first texture area 211 is inconsistent with the brightness of the second texture area 221. In other words, after the optical module is lit, it presents a lighting effect of alternating light and dark areas, with scattered points of light (such as...). Figure 5 As shown in the figure, it enhances the personalization and aesthetics of the optical module lighting, and can meet the personalized design needs of vehicle lights.
[0048] It should be noted that, taking the light rays directed toward the first textured area 211 as an example, the propagation distance refers to the distance the light rays travel from the first light source 10 to the first textured area 211. The shorter the propagation distance, the higher the energy received by the first textured area 211 and the higher the brightness. The light rays directed toward the second surface 22 are similar, and will not be described in detail here.
[0049] In some embodiments, the maximum value of the spacing d1 is less than the minimum value of the spacing d2, that is, the propagation distance of all the light rays from the first light source 10 to the first texture area 211 is less than the propagation distance of all the light rays from the first light source 10 to the second texture area 221, and the illumination brightness of the first texture area 211 is higher than that of the second texture area 221.
[0050] It is worth mentioning that in some embodiments, the minimum value of the spacing d1 can be greater than the maximum value of the spacing d2, that is, the illumination brightness of the first texture area 211 is lower than the illumination brightness of the second texture area 221. When observed by the human eye, the optical module still appears as alternating light and dark.
[0051] In some embodiments, the optical module further includes a bracket 30 configured to mount a 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 formed.
[0052] There are two first light guide components 20, that is, there are two first surfaces 21 (e.g. Figure 2 (as shown in 21a and 21b) and the two second surfaces 22 (as shown in 21a and 21b) Figure 2 As shown in Figures 22a and 22b, for ease of distinction, the two first light guide components 20 are distinguished by a and b, respectively. That is, when lit, there are two display areas that can be combined by the shape of the textured areas (first textured area 211 and second textured area 221), thereby improving the diversity of the display.
[0053] The bracket 30 and the two first light guide components 20 are integrated. In this embodiment, they can be formed by two-color injection molding, which helps to improve the control of the relative position between the bracket 30 and the two first light guide components 20, improves the processing accuracy, and thus improves the lighting effect of the optical module. In addition, the integrated molding avoids the installation steps between multiple parts and improves production efficiency.
[0054] In some embodiments, the optical module further includes a mounting frame 40, on which the first light guide component 20 is mounted via a bracket 30, and the mounting frame 40 is made of a reflective material.
[0055] The mounting bracket 40 is made of reflective material. Light emitted from the first light guide component 20 is reflected back to the first light guide component 20 after hitting the mounting bracket 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 being 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 textured area 211 and the second textured area 221 on the first light guide component 20 are lit. The optical utilization rate of the first light source 10 is not high and the light loss is relatively large. In some embodiments (e.g., the optical module is used as a position function light), it cannot meet the brightness requirements of the regulations. By setting the second light guide component 50 and the second light source 60, auxiliary lighting can be provided for the first light guide component 20, so that the overall brightness of the optical module can meet the brightness requirements of the regulations. 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 guide component 50 can be fixed in the mounting hole 31 by means of ultrasonic welding, which improves the stability of the installation of the second light guide component 50 and can prevent light leakage between the second light guide component 50 and the mounting hole 31; in some embodiments, other connection methods may 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 mounted on the same bracket 30. The relative positions of the second light guide component 50 and the two first light guide components 20 are controlled more precisely, which helps to improve the overall lighting effect.
[0060] In some embodiments, the second light source 60 is an LED on a printed circuit board. The LED can emit yellow light and red light. Yellow light can be used as a turn signal light source, and red light can be used as a position light source.
[0061] In some embodiments, the optical module further includes a third light guide component 70, the third light guide component 70 and the second light guide component 50 are arranged sequentially at intervals along the X-axis direction, and the light emitted from the second light source 60 is adjusted by the third light guide component 70 and then directed toward the second light guide component 50; the light-emitting surface of the third light guide component 70 is provided with a diffusion pattern 71, and the light-incident surface of the second light guide component 50 is provided with a converging pattern 51.
[0062] After passing through the diffusion pattern 71 on the light-emitting surface of the third light guide component 70, the light is diffused. The diffused light then passes through the convergence pattern 51 on the light-incident surface of the second light guide component 50 and enters the second light guide component 50, finally exiting from the light-emitting surface of the second light guide component 50. After the light is diffused, it helps to improve the uniformity of light emission. Furthermore, the convergence pattern 51 reduces the amount of light propagating to non-illuminated areas, avoiding a reduction in luminous flux and thus reducing the brightness. This ensures both the brightness of the light and the effect of homogenized light emission (the third light guide component 70 and the second light guide component 50 emit light as a whole).
[0063] It is worth mentioning that this setting can reduce the luminous power of the second light source 60, that is, using lamps with smaller power can meet the brightness value of the illumination, reducing energy consumption and the heat generated when the second light source 60 is working, and improving its service life.
[0064] In some embodiments, the second light guide component 50 has a textured surface around its periphery in the X-axis direction.
[0065] By setting a textured surface on the periphery of the second light guide component 50 in the X-axis direction, the internal structure can be concealed, and the bright spots of the LED beads can be weakened, resulting in a more uniform lighting effect.
[0066] On the other hand, this application also relates to a vehicle lamp, including any of the aforementioned optical modules. The vehicle lamp also includes a housing 80 and a light distribution lens 90. The light distribution lens 90 covers the housing 80 to form an accommodating space 100, and the optical module is accommodated in the accommodating space 100.
[0067] On the other hand, this application also relates to a vehicle including the aforementioned headlights.
[0068] The technical solution provided in this application aims to enhance the personalization of the optical module lighting by setting the first texture area 211 and the second texture area 221 alternately on the projection surface λ through orthogonal projection. The human eye can observe the pattern of the alternately set texture areas (the pattern of the first texture area 211 and the pattern of the second texture area 221). Compared with the traditional technology where the first light guide component 20 is lit up as a whole, in this application only the first texture area 211 and the second texture area 221 are lit up, which improves the aesthetics when lit up and can meet the personalized design requirements of vehicle lights.

Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships. In this application, "at least one" means one or more, and "more than one" means two or more.
