Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0036] The reflector, optical module, and vehicle light in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0037] In existing technologies, due to the diversity of vehicle shapes, it is difficult to achieve uniformity of observation on the luminous surface.
[0038] To address the aforementioned technical problems, this application provides a reflector disposed on a mounting surface. The reflector includes a plurality of first reflective sub-sections arranged sequentially. Each first reflective sub-section is configured to reflect incident light rays to the light-emitting side of the reflector. The first reflective sub-sections located at both ends of the reflector are an initial sub-section and an end sub-section. From the initial sub-section to the end sub-section, the angle between the principal optical axis of each first reflective sub-section and the principal optical axis of the initial sub-section gradually increases on the orthographic projection onto the mounting surface. This will be described in detail below.
[0039] See Figure 1 In one embodiment, the reflector 10 is disposed on the mounting surface (e.g., Figure 1 and Figure 3 As shown in the mid-plane η (hereinafter the same), the reflector 10 includes a plurality of first reflective sub-parts 11 arranged in sequence. The first reflective sub-parts 11 are configured to reflect light incident on the first reflective sub-parts 11 to the light-emitting side of the reflector 10. The first reflective sub-parts 11 located at both ends of the reflector 10 are an initial sub-part 11a and an end sub-part 11b. From the initial sub-part 11a to the end sub-part 11b, the orthographic projection of the angle between the principal optical axis of each first reflective sub-part 11 and the principal optical axis of the initial sub-part 11a on the mounting surface gradually increases.
[0040] In this embodiment, the angle between the principal optical axis of each first reflective sub-part 11 and the principal optical axis of the initial sub-part 11a gradually increases on the orthographic projection onto the mounting surface. This ensures that the energy emitted by the reflector 10 at various angles is nearly consistent, preventing the light emitted by the reflector 10 in a single direction from becoming too concentrated. At the same time, since different first reflective sub-parts 11 emit light in different directions, the irradiance in each direction will not differ significantly. This results in a consistent viewing effect when viewing the lamp from different angles, achieving uniformity of multi-angle observation when the headlights are lit and improving the display quality of the headlights.
[0041] The angle between the principal optical axis of each first reflector sub-section 11 and the principal optical axis of the initial sub-section 11a gradually increases on the orthographic projection onto the mounting surface. This means that the light reflected by each first reflector sub-section 11 will not interfere with each other, which is beneficial to improving the lighting effect of the headlights.
[0042] In some embodiments, the orthographic projection of the angle between the principal optical axes of two adjacent first reflective sub-parts 11 onto the mounting surface is a fixed value. That is, from the initial sub-part 11a to the final sub-part 11b, the orthographic projection of the angle between the principal optical axis of each first reflective sub-part 11 and the principal optical axis of the initial sub-part 11a onto the mounting surface increases by the same amount, making the overall structure of the reflector 10 more uniform and facilitating the processing and shaping of the reflector 10. In some embodiments, the angle can be increased to different degrees, and the relevant angles can be set according to factors such as the actual shape of the reflector 10.
[0043] It should be noted that the principal optical axis of the initial sub-part 11a is as follows: Figure 1 and Figure 4 As shown by the middle straight line c, the principal optical axis of the last sub-part 11b is as follows: Figure 1 and Figure 4 As shown by the straight line d. The mounting surface η is the base surface of the carrier on which the reflector 10 is positioned and fixed. For example, when the reflector is mounted on the support surface of the heat sink, the support surface of the heat sink is the mounting surface. In some embodiments, the mounting surface η can also be set as... Figure 3 The area above the reflector 10 in the field of view is determined according to the specific mounting structure of the reflector 10, and is not limited thereto; in other embodiments, the mounting surface η can be a solid surface or a virtual surface, and this application does not impose any restrictions.
[0044] See Figure 2 and Figure 3In one embodiment, the reflector 10 has a reflective cavity 12. The cavity wall of the reflective cavity 12 includes a first wall surface 121 and a second wall surface 122. The second wall surface 122 surrounds the periphery of the first wall surface 121. The first wall surface 121 includes a reflective sub-surface 1211 and a connecting sub-surface 1212. Multiple reflective sub-surfaces 1211 are arranged sequentially, and the connecting sub-surfaces 1212 are connected between adjacent reflective sub-surfaces 1211. The reflective sub-surfaces 1211 are provided with reflective patterns, and the second wall surface 122 and the connecting sub-surfaces 1212 are provided with textured surfaces.
[0045] In this embodiment, the light illuminating the second wall surface 122 and the connecting sub-surface 1212 is diffused and distributed under the action of the texture, avoiding specular reflection that would cause glare and bright spots, effectively improving the uniformity of the headlights under multi-angle observation; and the texture redistributes the stray light that originally caused glare and bright spots, enhancing the overall illumination intensity.
[0046] It should be noted that in this embodiment, one first reflective sub-part 11 corresponds to one reflective sub-surface 1211. In some embodiments, the position of the principal optical axis of the first reflective sub-part 11 can be adjusted by the shape, orientation, etc. of the reflective sub-surface 1211.
[0047] In one embodiment, the portion of the second wall 122 near the light-emitting opening of the reflector 10 is inclined to increase the light-emitting opening of the reflector 10.
[0048] The light-emitting opening of the reflector 10 is expanded outward, which effectively improves the reflection efficiency of the reflector 10.
[0049] See Figure 4 In one embodiment, the orthographic projection of the angle between the main optical axis of the initial sub-part 11a and the main optical axis of the end sub-part 11b on the mounting surface is α, which satisfies: 10°≤α≤30°, for example 10°, 20°, 30°, etc.
[0050] When the value of α is greater than 30°, the reflector 10 tends to be more and more curved, which increases the processing difficulty of the reflector 10 and other parts that cooperate with the reflector 10, thereby increasing the production cost. In addition, the excessively curved reflector 10 is not conducive to the fixed installation of the reflector 10 itself, which increases the assembly difficulty.
[0051] When the value of α is less than 10°, the reflector 10 will tend to be flat. The processing cost of a flat reflector 10 is lower. The uniformity of illumination can be achieved by setting a light-diffusing plate on the light-emitting side of the reflector 10, without increasing the production cost by designing a specific reflector 10.
[0052] On the other hand, this application also relates to an optical module, including any of the aforementioned reflectors 10. The optical module further includes a light distribution lens 30 and a light adjustment element 20. The light distribution lens 30 includes a first sub-section 31 and a second sub-section 32 connected to each other at an angle. The first sub-section 31 is configured to receive light emitted from the reflector 10, and the second sub-section 32 is configured to receive light emitted from the light adjustment element 20; with the light emitted perpendicular to the main light output direction of the second sub-section 32 (e.g., Figure 4 The reference plane γ (shown in the direction of X, the same below) is the reference plane. The reference plane is set on the light-emitting side of the light distribution lens 30. The distance between the first sub-part 31 and the reference plane in the main light-emitting direction of the second sub-part 32 gradually decreases in the direction from the first sub-part 31 to the second sub-part 32.
[0053] The distance between the first sub-part 31 and the reference plane in the main light-emitting direction of the second sub-part 32 gradually decreases in the direction from the first sub-part 31 to the second sub-part 32, that is, the first sub-part 31 exhibits... Figure 4 The tilted state shown makes the first sub-part 31 (reflector 10) tilted in the vertical direction ( Figure 4 The size of the reflector 10 is reduced in the viewing angle (the same below); when the main optical axis of all the first reflector sub-parts 11 is consistent with the main light emission direction of the second sub-part 32, the light emitted by the reflector 10 is too concentrated, and the brightness of the first sub-part 31 is greater than that of the second sub-part 32 when observing the headlights on the left.
[0054] In this embodiment, the orthographic projection of the angle between the principal optical axis of each first reflective sub-section 11 in the reflector 10 and the principal optical axis of the initial sub-section 11a on the mounting surface gradually increases. Different first reflective sub-sections 11 emit light in different directions, avoiding the light emitted by the reflector 10 in a single direction being too concentrated. When observing the second sub-section 32 from the left, only some of the light emitted from the first reflective sub-sections 11 in the reflector 10 can enter the human eye and be observed. This is beneficial for the brightness of the second sub-section 32 when it is lit to be consistent with the brightness of the first sub-section 31 when it is lit, which is beneficial for the uniformity of the overall lighting of the light distribution lens 30.
[0055] The first sub-part 31 and the second sub-part 32 are respectively provided with a reflector 10 and a light adjustment element 20. In actual use, the first sub-part 31 and the second sub-part 32 can be set as vehicle lights with different functions, such as position lights and brake lights, according to the usage requirements. Integrating vehicle lights with different functions together improves assembly efficiency and reduces space occupation, providing space for the arrangement and installation of other vehicle parts.
[0056] In practical applications, this optical module is used in vehicle taillights. Due to the personalized design of vehicle styling, the shape of the vehicle tailgate (used for the installation of the optical module) changes abruptly, with the upper and lower sides forming an inclined L-shape. As different people have different heights and eye heights, the angles at which they observe the headlights are different. By setting the angle between the principal optical axis of each first reflective sub-part 11 in the reflector 10 and the principal optical axis of the initial sub-part 11a to gradually increase the orthographic projection on the mounting surface, it is beneficial to ensure the uniformity of the overall illumination of the headlights when observed by different people (observing from different angles).
[0057] It should be noted that in order to ensure the uniformity of the overall illumination of the headlights, it is necessary to ensure the uniformity of the second sub-section 32 when viewed from multiple angles. In some embodiments, the light adjustment element 20 (in some embodiments, it can be a reflector 10, a thick-walled component, etc., which is not specifically limited here and is determined according to actual use) can be divided into multiple second reflective sub-sections 21, similar to the reflector 10. The uniformity of the second sub-section 32 when viewed from multiple angles can be achieved by setting the principal optical axis angle of the second reflective sub-section 21. Alternatively, the uniformity of the light emitted from the second sub-section 32 can be ensured by setting components such as a light-diffusing plate, and it is not limited to these.
[0058] In addition, for multi-angle observation of the first sub-part 31, this embodiment is... Figure 4 The first sub-section 31 is observed from the left side, the top side, and the area between the two directions. By setting the angle of the principal optical axis of each first reflective sub-section 11, the light energy that the human eye can observe is consistent when observed from different angles, which is beneficial to the uniformity of the illumination of the first sub-section 31. Moreover, when observed from the left side, the brightness of the second sub-section 32 is consistent with the brightness of the first sub-section 31, which is beneficial to the overall uniformity of illumination. Of course, in some embodiments, the first sub-section 31 and the second sub-section 32 can be configured as headlights with different functions according to design requirements. When illuminated simultaneously, it is not necessary to ensure the uniformity of the illumination of the upper and lower headlight sections. The brightness of the upper and lower headlight sections can be set to different brightness levels, and this is not limited to this.
[0059] See Figure 5 In one embodiment, the optical module further includes a first light guide component 40 and a second light guide component 50. The first light guide component 40 is disposed between the reflector 10 and the first sub-part 31, and the second light guide component 50 is disposed between the light adjustment element 20 and the second sub-part 32. In the main light emission direction of the second sub-part 32, the maximum distance from the first sub-part 31 to the reference plane is greater than the maximum distance from the second sub-part 32 to the reference plane. The first light guide component 40 is disposed between the first sub-part 31 and the first sub-part 32 in the main light emission direction (e.g., in the main light emission direction of the first sub-part 31). Figure 4 The thickness of the second light guide component 50 in the direction Y (as shown below) is less than the thickness of the second light guide component 50 in the main light emission direction of the second sub-part 32.
[0060] In this embodiment, the maximum distance from the first sub-part 31 to the reference surface (the distance in the main light-emitting direction of the second sub-part 32, the same below) is greater than the maximum distance from the second sub-part 32 to the reference surface. That is, the tilt of the first sub-part 31 is greater than the tilt of the second sub-part 32. In other words, when the headlight is lit, the light emitted through the first sub-part 31 needs to travel a longer distance to reach the reference surface compared to the light emitted through the second sub-part 32. When the thickness of the first light guide component 40 and the second light guide component 50 is the same, the light energy of the two (the light emitted from the first sub-part 31 and the light emitted from the second sub-part 32) reaching the reference surface is inconsistent, resulting in uneven lighting. However, since the thickness of the first light guide component 40 is less than the thickness of the second light guide component 50, it can be ensured that the light energy of the two reaching the reference surface is consistent, which is beneficial to ensuring the overall lighting uniformity.
[0061] In some embodiments, the thickness of the first light guide member 40 can be made gradually according to the tilt of the first sub-part 31 and the second sub-part 32, for example... Figure 4 From the perspective of the light guide component 40, the thickness gradually decreases from left to right, which is beneficial to improving the uniformity of illumination, and not only that; the second light guide component 50 is also set in the same way, which will not be described in detail here.
[0062] It should be noted that the thickness of the first light guide component 40 and the second light guide component 50 is the thickness used for light propagation.
[0063] In one embodiment, the first light guide component 40 is connected to the light-emitting side of the reflector 10 via a connecting structure 60, and the connecting structure 60 is disposed on the light-incident side of the first light guide component 40.
[0064] In this embodiment, the connecting structure 60 is disposed on the light-incident side of the first light guide component 40, that is, the first light guide component 40 can block the connecting structure 60, which is beneficial to improving the quality of the vehicle headlight when it is static.
[0065] In some embodiments, the first light guide component 40 may use an opaque light-monopolizing material, which ensures both the uniformity of the light emitted from the first light guide component 40 and improves the shielding properties of the first light guide component 40.
[0066] It should be noted that the second light guide component 50 can also be arranged between the light adjustment element 20 in this way, which will not be elaborated here.
[0067] See Figure 5 and Figure 6 In one embodiment, the optical module further includes a bracket 70, which is disposed between the angle formed by the first sub-part 31 and the second sub-part 32, and the bracket 70 is connected to the reflector 10 and the light adjustment element 20 respectively.
[0068] In this embodiment, the reflector 10 and the light adjustment element 20 are connected by 70 brackets, which can effectively avoid phenomena such as outward expansion, inward contraction and twisting between the reflector 10 and the light adjustment element 20, improve the overall rigidity of the optical module and help improve the lighting effect.
[0069] In some embodiments, the optical module further includes a first decorative ring 90 and a second decorative ring 100 connected to each other. The first decorative ring 90 is connected to the light-emitting side of the first light guide component 40, and the second decorative ring 100 is connected to the light-emitting side of the second light guide component 50. They can be connected by means of laser welding or other methods, but are not limited to these. One side of the bracket 70 can be connected to the reflector 10, and the other side can be connected to the second decorative ring 100. By staggering the connection points of the bracket 70, from the perspective of the optical module as a whole, the bracket 70 is connected in different places, which is beneficial to the improvement of the overall rigidity and facilitates the arrangement of the connection points of the bracket 70, which is beneficial to the spatial layout.
[0070] It should be noted that the trim ring (including the first trim ring 90 and the second trim ring 100) includes a visible portion and a non-visible portion surrounding the visible portion. The visible portion is for light transmission, ensuring that light from the optical module passes through smoothly. The non-visible portion can shield the internal mounting structure and defects, improving the quality of the headlight when stationary. Textured surfaces can be provided on the light-emitting and light-receiving sides of the visible portion of the trim ring, which is beneficial for light diffusion and improves the uniformity of illumination. For example, the texture depth on the light-receiving side is less than that on the light-emitting side. The smaller texture depth on the light-receiving side (relative to the texture depth on the light-emitting side) avoids excessive light dispersion while ensuring uniform illumination and light transmission, ensuring that the headlight brightness meets design requirements. The larger texture depth on the light-emitting side increases the light diffusion efficiency and the illumination range of the headlight. Furthermore, due to the larger texture depth on the light-emitting side, it can better shield the internal mounting structure and defects, preventing the internal mounting structure and defects of the headlight from being seen when the headlight is stationary (not illuminated), thus improving the quality of the headlight.
[0071] When the optical module is applied to vehicle lights, the light distribution lens 30 is placed on the housing of the vehicle light. The aforementioned reflector 10, light adjustment element 20, first light guide component 40, second light guide component 50 and other components are all located inside the housing, which will not be described in detail here.
[0072] In some embodiments, a third light guide component 80 may also be provided on the bracket 70. The optical module has three different light guide components, which can realize the use of vehicle lights with different functions. Integrating vehicle lights with different functions into one optical module reduces space occupation and is beneficial to vehicle styling design, etc.
[0073] On the other hand, this application also relates to a vehicle light, including any of the aforementioned optical modules.
[0074] The technical solution provided in this application aims to ensure that the energy emitted by the reflector 10 at various angles is nearly uniform by gradually increasing the orthographic projection of the angle between the principal optical axis of each first reflector sub-part 11 and the principal optical axis of the initial sub-part 11a on the mounting surface. This improves the uniformity of the headlight when it is lit from multiple angles. The reflector 10 can be designed with different angles and shapes according to the headlight shape. By varying the orthographic projection of the angle between the principal optical axis of each first reflector sub-part 11 and the principal optical axis of the initial sub-part 11a on the mounting surface, the light energy that can be observed by the human eye is consistent when the reflector 10 is observed from multiple angles. This is beneficial to the uniformity of the headlight and improves the headlight quality. Furthermore, the light reflected by each first reflector sub-part 11 will not interfere with each other, which is beneficial to improving the headlight lighting effect.
