[0032] The processing technology of the light-emitting structure, vehicle and light distribution mirror in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the prior art, due to the different colors of the car bodies, the light absorption rate is different, which leads to the same light having inconsistent brightness under the influence of different colored car bodies, uneven lighting effect, and certain defects in the lighting effect.

[0034] In order to solve the above technical problems, an embodiment of the present application provides a light-emitting structure, including a light source module and a light distribution mirror, wherein the light source module is used to emit light; the light distribution mirror is spaced apart and arranged on the side of the light source module emitting light; wherein the two side surfaces of the light distribution mirror in the thickness direction are respectively a first surface and a second surface, and the first surface is arranged between the light source module and the second surface; the first surface is coated with a light diffusion layer. By coating the light diffusion layer on the side of the light distribution mirror facing the light source module, the brightness of the light source can be adjusted according to different vehicle body colors to adapt to the brightness requirements of different vehicle body colors, thereby ensuring the uniformity and consistency of the light effect. This will be elaborated below.

[0035] See also Figure 1 In one embodiment, the light-emitting structure includes a light source module 10 and a photometric lens 20. The photometric lens 20 is spaced apart from the light source module 10, and the photometric lens 20 is arranged on the side where the light source module 10 emits light, that is, the light emitted by the light source module 10 passes through the photometric lens 20. In the thickness direction of the photometric lens 20, the two surfaces of the photometric lens 20 are respectively a first surface 21 and a second surface 22. The first surface 21 is arranged between the light source module 10 and the second surface 22, that is, the first surface 21 faces the light source module 10, and a light diffusion layer 23 (such as Figure 2 The light emitted by the light source module 10 can achieve different brightnesses through the different thicknesses of the light diffusion layer 23, and can be adjusted to a suitable brightness according to the different colors of the vehicle body. The brightness can be adjusted without the need for mold or electronic solution design, the adjustment cost is low, and the different brightness requirements of customers can be quickly responded to.

[0036] It should be noted that, in some embodiments, the light source module 10 can be a combination of a light-emitting unit 11 and a circuit board 12, and the light-emitting unit 11 is arranged on the circuit board 12, and the light-emitting unit 11 is controlled by the circuit board 12; in some embodiments, the light-emitting unit 11 can be a single LED lamp bead or a combination of multiple LED lamp beads to form a light-emitting unit 11, or it can be a monochrome lamp bead or an RGB lamp bead, which is not specifically limited and is determined according to the actual lighting requirements of the components; in some embodiments, the light-emitting unit 11 can be arranged on a plane or a curved surface to meet diversified designs. At the same time, the light-emitting unit 11 can be controlled individually, which can be achieved through a pre-set algorithm to meet the personalized needs of users.

[0037] In some embodiments, the light diffusion layer 23 may be a milky white scattering paint, which can evenly distribute light through scattering. The milky white color can ensure the brightness of the light, thereby making the overall light output of the light-emitting structure softer and fuller. Of course, in other embodiments, other materials can also be used, which is not limited here.

[0038] In this embodiment, the photometric mirror 20 includes a mounting portion 26 and a light-transmitting portion 27. The mounting portion 26 is arranged on the peripheral side of the light-transmitting portion 27, that is, the mounting portion 26 is arranged on the edge of the light-transmitting portion 27. The mounting portion 26 is fixedly connected to the mounting bracket 30 to achieve fixed installation of the photometric mirror 20. At the same time, the light diffusion layer 23 is laid on the light-transmitting portion 27, and the light emitted by the light source module 10 first passes through the light diffusion layer 23 and then passes through the light-transmitting portion 27 to be emitted; the photometric mirror 20 can be integrally formed by a two-color injection molding process, and can be made of transparent material or light-diffusing material. In some embodiments, the mounting portion 26 can be black or any color, depending on actual use.

[0039] Please refer to Figure 1 as well as Figure 2 In one embodiment, a pigment layer 24 (such as Figure 2 As shown), in the actual production process, it is the color of the vehicle body. Different colors have different absorption rates of light. The pigment layer 24 is provided with a plurality of luminous dot matrices 25 (such as Figure 3 As shown), the light emitted by the light source module 10 passes through the light distribution lens 20 and then is emitted through the light-emitting dot matrix 25 to achieve different visual effects. Each light-emitting dot matrix 25 includes a plurality of arrays of light-emitting holes 251. The intensity of the light can be further adjusted by adjusting the aperture size of the light-emitting hole 251 to adapt to different vehicle body colors.

[0040] It should be noted that due to the small thickness of the light diffusion layer 23 and the pigment layer 24, Figure 2The light diffusion layer 23 and pigment layer 24 are provided for illustrative purposes only, to facilitate understanding of the layer structure. They do not represent a dimensional ratio between the two layers and the lens 20, nor do they represent their actual thickness. In the above embodiment, the lens 20 is provided with the light diffusion layer 23 on the side facing the light-emitting module 10, and the light-emitting array 25 on the other side. The intensity of the emitted light can be controlled by controlling both the thickness of the light diffusion layer 23 and the aperture size of the light-emitting holes 251 in the light-emitting array 25. In some embodiments, the intensity of the emitted light can be adjusted by controlling either the thickness of the light diffusion layer 23 or the aperture size of the light-emitting holes 251 in the light-emitting array 25. The light-emitting holes 251 can be engraved into the pigment layer 24 using laser engraving technology. In actual production, a protective layer, such as varnish, is applied to the pigment layer 24 after the light-emitting holes 251 are engraved. Furthermore, in some embodiments, the light-emitting array 25 can have other shapes according to design requirements, and the intensity of the emitted light can be controlled by varying the area of ​​the shape to meet diverse usage requirements.

[0041] See also Figure 1 and Figure 4 In one embodiment, the light-emitting structure further includes a mounting bracket 30, which is arranged between the light source module 10 and the photometric mirror 20. The light source module 10 is fixed to one end of the mounting bracket 30, and the photometric mirror 20 is fixedly mounted on the other end of the mounting bracket 30. The light source module 10 and the photometric mirror 20 are spaced apart by the arrangement of the mounting bracket 30, and the distance between the light source module 10 and the photometric mirror 20 can be adjusted by the different sizes of the mounting bracket 30 in the light emission direction; in this embodiment, the mounting bracket 30 is arranged on the peripheral side of the light-emitting unit 11, and the mounting brackets 30 on the peripheral side of the same light-emitting unit 11 are surrounded to form a light channel 40, which can isolate the light emitted between adjacent light-emitting units 11 and avoid light interference. The light is reflected back and forth in the light channel 40 until it is finally emitted (such as Figure 4 As shown), the reciprocating reflection increases the uniformity of the light. When the light passes through the reciprocating reflection of the light channel 40 and then scatters through the light diffusion layer 23, the uniformity of the emitted light is further improved, making the boundary of the light clearer and sharper. At the same time, the light channel 40 can suppress the scattering of the light beam, avoid the overflow of the emitted light, and improve the display effect (as shown). Figure 7 shown).

[0042] It should be noted that, in this embodiment, the mounting bracket 30 is arranged on the circumferential side of a single light-emitting unit 11. In some embodiments, the mounting bracket 30 may also be provided on the circumferential sides of multiple light-emitting units 11 in the same column or row or adjacent to each other to form a light channel 40. The specific arrangement structure of the light channel 40 is determined according to actual usage requirements.

[0043] Please continue reading Figure 4In one embodiment, a group of light-emitting dot matrices 25 and a light-emitting unit 11 are respectively provided at both ends of the same light channel 40, that is, the light emitted by a light-emitting unit 11 passes through the light channel 40 and is used to illuminate a group of light-emitting dot matrices 25. Such an arrangement can effectively isolate the light interference between adjacent light-emitting units 11, and in some embodiments, the light-emitting unit 11 can be controlled individually to control the lighting or extinguishing of the light-emitting dot matrices 25, which can meet the diversity of use; for example, in the application of the light-emitting grid, different visual effects can be achieved by turning on and off different light-emitting dot matrices 25.

[0044] See also Figure 5 as well as Figure 7 In one embodiment, the second surface 22 is coated with a pigment layer 24, the light absorption rate of the pigment layer 24 is η, and the thickness of the light diffusion layer 23 is hμm (not shown in the figure), which satisfies the following conditions: η=(-0.8h+94) / 100, 30%≤η≤80%, 30≤h≤80, h is, for example, 30, 50, 60, 80, etc., and η is, for example, 30%, 46%, 54%, 70%, etc.; Figure 5 In the figure, the vertical axis increases vertically from bottom to top, and the absorption rate of light gradually increases, and the horizontal axis decreases from left to right. In this way, the higher the absorption rate η of light (that is, the darker the color of the car body), the smaller the thickness of the light diffusion layer 23, the stronger the emitted light, and the brighter the display. Therefore, the intensity of the emitted light can be adjusted by controlling the thickness of the light diffusion layer 23, so that even after spraying different car body colors, the lighting effect can still be consistent, ensuring that the display effect of the emitted light with the same lighting intensity after passing through the light-emitting structure is consistent, thereby improving the visual effect. It has been verified that when h and η satisfy the above relationship and are within the above value range, the consistency of the light is best, and the brightness can be adjusted without the design of molds or electronic solutions. The adjustment cost is low, and it can quickly respond to customers' different demands for brightness.

[0045] See also Figure 6 as well as Figure 7 In one embodiment, the light absorption rate of the pigment layer 24 is η, and the diameter of the light-emitting hole 251 is d mm (not marked in the figure), which satisfies: η = (93.75d + 1.875) / 100, 30% ≤ η ≤ 80%, 0.3 ≤ d ≤ 0.8, d is, for example, 0.3, 0.5, 0.6, 0.8, etc., and η is, for example, 30%, 48.8%, 58.1%, 76.9%, etc.; Figure 6In the figure, the vertical axis increases vertically from bottom to top, and the absorption rate of light gradually increases, and the horizontal axis increases numerically from left to right. In this way, the higher the absorption rate η of light (that is, the darker the color of the car body), the larger the diameter of the light-emitting hole 251, the stronger the emitted light, and the brighter the display. Therefore, the intensity of the transmitted light can be adjusted by controlling the diameter size of the light-emitting hole 251, so that even after spraying different car body colors, the lighting effect can still be consistent, ensuring that the emitted light of the same lighting intensity has a consistent display effect after passing through the light-emitting structure, thereby improving the visual effect. It has been verified that when d and η satisfy the above relationship and are within the above value range, the consistency of the light is best, and the brightness can be adjusted without the design of a mold or electronic solution. The adjustment cost is low, and it can quickly respond to customers' different demands for brightness.

[0048] It should be noted that laser engraving is a process of using a high-intensity focused laser beam emitted by a laser to evaporate the surface material at the focal point to expose the deeper material, or to cause chemical and physical changes in the surface material through light energy to leave traces, or to burn away part of the material through light energy to "carve" out traces, or to burn away part of the material through light energy to reveal the desired etching pattern.

[0049] The technical solution provided in the embodiment of the present application aims to provide a light diffusion layer 23 of different thicknesses on the surface of the light distribution lens 20 facing the light source module 10 and adjust the diameter of the light-emitting hole 251, so that the light emitted by the light source module 10 can be adjusted through the light diffusion layer 23 and the light-emitting hole 251; the light emitted by the light source module 10 can reach the required brightness according to different usage requirements, and the brightness can be adjusted without the design of molds or electronic solutions.
