[0043] With the improvement of consumer aesthetic concept, the design of car lamp modeling gradually develops towards the direction of more delicate and more scientific and technological. Now, the car lamp modeling with more prominent line feeling, better light uniformity and stronger three-dimensional effect has become the mainstream trend in the market. Such modeling not only can add unique visual charm to the car and improve the overall appearance quality, but also can reflect the technical strength and design concept of the car brand to a certain extent. In practical application, such car lamp modeling is more commonly realized by the light emitting structure of LED light source cooperating with thick wall part. The LED light source has the advantages of high brightness, low energy consumption and long service life, and the thick wall part can effectively conduct and diffuse light, and through the cooperation of the two, a variety of car lamp modeling can be generated by changing the shape and position of the thick wall part.

[0044] However, according to the research of the applicant, it is found that in practical application, the traditional direct injection type or reflective type thick wall part is prone to high bright spot or dark area with relatively dark brightness, so that the brightness of the car lamp is uneven when lighting. Please refer to Figure 1 In order to solve the problem of poor light uniformity of the traditional thick wall part, some technical solutions adopt the combination of two thick wall parts. The light emitted by the light source plate 1 is received by the first thick wall part 2-1, the light propagates and diffuses in the first thick wall part 2-1, and finally is emitted from the light emitting surface of the first thick wall part 2-1, and then the light enters the second thick wall part 2-2, propagates and diffuses in the second thick wall part 2-2, and finally is emitted from the light emitting surface of the second thick wall part 2-2. Among them, the second thick wall part 2-2 plays a role in further uniformly distributing the light. This light emitting structure improves the distribution of light to a certain extent, so that the light emitting of the thick wall part is more uniform. But this light emitting structure also has the disadvantage of large volume. The larger volume not only increases the overall weight of the car lamp, but also occupies more internal space of the car lamp, which brings certain difficulty to the layout and design of other parts of the car lamp.

[0045] In view of this, the utility model provides a light-emitting structure to solve or at least alleviate the above problems.

[0046] In an embodiment of the utility model, please refer to Figures 2 to 4 , the light-emitting structure 1000 includes light source plate 1 and thick wall piece 2, wherein, light source plate 1 includes multiple spaced arrangement's lamp pearl 11, and lamp pearl 11 is used to emit light 111;Thick wall piece 2 includes main body 21 and multiple light collecting parts 22, and light collecting part 22 is arranged at the bottom of main body 21, and light collecting part 22 includes light collecting hole 221, and light collecting hole 221 faces lamp pearl 11, and light collecting hole 221 is set up one by one with lamp pearl 11;Main body 21 includes oppositely arranged divergent surface 211 and reflection part 212, and reflection part 212 includes multiple primary reflection surface 2121 and multiple secondary reflection surface 2122, and along the extension direction X (see Figure 3 The direction indicated by the arrow X in the middle), primary reflection surface 2121 and secondary reflection surface 2122 are alternately arranged in sequence, and primary reflection surface 2121 faces light collecting hole 221, and primary reflection surface 2121 and secondary reflection surface 2122 are both inclinedly arranged;Please refer to Figure 5 And Figure 6 , light 111 enters main body 21 through light collecting part 22, is reflected to secondary reflection surface 2122 and divergent surface 211 by primary reflection surface 2121, and the part light 111 falling on secondary reflection surface 2122 is reflected to divergent surface 211 after reflection.

[0047] Specifically, in the embodiment, light source plate 1 adopts one of LED lamp plate and laser lamp plate.Thick wall piece 2 is integrally formed, and the manufacturing material includes one of polycarbonate, polymethyl methacrylate and other light-transmitting materials.In the embodiment, primary reflection surface 2121 and secondary reflection surface 2122 are both inclinedly arranged, along the direction gradually away from light source plate 1, the distance between primary reflection surface 2121 and secondary reflection surface 2122 and divergent surface 211 is smaller, and primary reflection surface 2121 faces light collecting hole 221, so that light 111 conducted to main body 21 in light collecting hole 221 can be reflected to secondary reflection surface 2122 and divergent surface 211 under the action of primary reflection surface 2121, on this basis, secondary reflection surface 2122 can reflect light 111 falling on the reflection surface again to reflect the part light 111 to divergent surface 211. Please refer to Figure 6 , it should be noted that, along the direction away from light source plate 1, the diameter of light collecting hole 221 gradually reduces, and the top of light collecting hole 221 is provided with light collecting patterns, and the light collecting patterns cooperate with the inner wall of light collecting hole 221 to play the role of converging light 111, and this setting can reduce the waste of light energy to improve the optical efficiency of light path.

[0048] The technical scheme provided by the embodiment makes the light rays 111 emitted by the lamp bead 11 after being aggregated by the light collecting part 22 to form incident light, pass through the primary reflection of the main reflection surface 2121 to the secondary reflection surface 2122 and the divergence surface 211, the part of the light rays 111 falling on the secondary reflection surface 2122 pass through the secondary reflection of the secondary reflection surface 2122 to the divergence surface 211 again, and the incident light can be uniformly dispersed on the divergence surface 211 after twice reflection, so that the bright spots or dark areas in the divergence surface 211 are eliminated, the light emitting effect of the divergence surface 211 is more uniform, meanwhile, the light emitting structure 1000 does not need to be provided with multiple thick-walled parts 2, and the volume of the thick-walled part 2 does not need to be increased, so that the defect that the light emitting structure 1000 has a large volume can be avoided.

[0049] Further, please refer to Figure 3 With Figure 4 In an embodiment of the present application, the surface of the main reflection surface 2121 is provided with a first optical pattern, and the first optical pattern is used for reflecting the light rays 111 to the divergence surface 211 and the secondary reflection surface 2122; the secondary reflection surface 2122 is provided with a second optical pattern, and the second optical pattern is used for reflecting the light rays 111 to the divergence surface 211. This staged reflection mechanism can significantly improve the utilization rate of the light rays 111 and avoid the problem of uneven brightness caused by the long light guide in the traditional design. The divergence surface 211 is the final light emitting surface, and the light rays 111 are projected to the divergence surface 211 at different angles through the alternate reflection of the main reflection surface 2121 and the secondary reflection surface 2122. Through the microstructure design of the first optical pattern on the main reflection surface 2121 and the second optical pattern on the secondary reflection surface 2122, the local dark area can be effectively eliminated, and more uniform distribution of the light rays 111 can be realized. The first optical pattern is used for controlling the main reflection direction of the light rays 111, and the second optical pattern is used for twice scattering or collimation of the residual stray light. This design can meet the requirements of clearness of the cut-off line and light type expansion at the same time. At the same time, by setting the pattern in the reflection surface, the wavelength deviation of the light rays 111 in multiple reflections can be reduced, the chromatic aberration and halo phenomenon can be reduced, and the visual comfort can be improved.

[0050] It should be noted that the first optical pattern and the second optical pattern are integrally formed with the thick-walled part 2 when the thick-walled part 2 is produced. According to the design requirements, the types of the first optical pattern and the second optical pattern can be flexibly adjusted.

[0051] In an embodiment of the utility model, the first optical pattern comprises arrayed checkered arc surface patterns, and the second optical pattern comprises arrayed strip patterns. Specifically, the first optical pattern comprises one of arrayed checkered arc surface patterns, rhombic arc surface patterns and triangular arc surface patterns, and the second optical pattern comprises one of arrayed strip patterns and the above pattern types. In this embodiment, in order to facilitate design and manufacture and achieve the expected optical effect, the first optical pattern adopts arrayed checkered arc surface patterns, and the second optical pattern adopts arrayed strip patterns. The checkered arc surface patterns of the main reflecting surface 2121 are similar to the structure of "compound eye", and the arc surface is divided into bundles of light rays 111, which reduces the local light intensity concentration in the diverging surface 211 and avoids the appearance of bright spots or dark areas. Each checkered unit can disperse the incident light into multiple directions for reflection, and a part is directly transmitted to the diverging surface 211, and another part is reflected to the secondary reflecting surface 2122 for secondary reflection, thereby improving the overall light uniformity. The strip patterns of the secondary reflecting surface 2122 are arranged longitudinally or obliquely, and the regular texture can guide the light rays 111 to diffuse along a specific angle, further eliminate stray light and ensure that the angle distribution of the light rays 111 received by the diverging surface 211 is more uniform.

[0052] Further, please refer to Figure 2 With Figure 5 In an embodiment of the utility model, the diverging surface 211 is provided with diverging optical patterns, and the diverging optical patterns comprise arrayed corn kernel patterns. The arrayed concave-convex structure of the corn kernel patterns diffuses the light rays 111 transmitted by the main reflecting surface 2121 and the secondary reflecting surface 2122 through micro-curved surface refraction and diffuse reflection. For example, after the checkered arc surface of the main reflecting surface 2121 divides the light rays 111 into bundles, the strip patterns of the secondary reflecting surface 2122 direct light, and finally through the random scattering of the corn kernel patterns on the diverging surface 211, the residual bright-dark boundary is eliminated. The spherical cap unit structure of the corn kernel patterns can expand the effective light angle of the diverging surface 211 to more than 120°, while avoiding the generation of a granular feeling of light on the diverging surface 211, and meeting the requirements of the light intensity distribution in the horizontal and vertical directions of the vehicle lamp regulations. In addition, from the appearance, the arrayed layout of the corn kernel patterns can produce a diamond-cut-like appearance effect when lighting, thereby improving the appearance quality of the vehicle lamp.

[0053] In an embodiment of the utility model, first included angle is arranged between main reflection surface 2121 and secondary reflection surface 2122, definition: first included angle is alpha, alpha satisfies: 0 ° < alpha < 180 °. When alpha is in acute angle range (such as 30 ° < alpha < 90 °), the light 111 of main reflection surface 2121 is incident to secondary reflection surface 2122 with specific angle after first reflection, and multiple reflection path is formed. This design can prolong optical path, reduce the transverse attenuation of light in thick wall part 2, and improve the uniformity of light 111. If alpha is close to 180 ° (such as 150 ° < alpha < 170 °), main secondary reflection surface 2122 is approximately parallel arrangement, and is suitable for flattening car lamp structure (such as through type tail lamp). By adjusting the angle of alpha, the square arc surface pattern of main reflection surface 2121 and the strip pattern of secondary reflection surface 2122 can cooperatively form specific light type. Meanwhile, the non-coplanar design of main reflection surface 2121 and secondary reflection surface 2122 can increase the heat dissipation area, which is beneficial to the heat dissipation of thick wall part 2.

[0054] Please refer to Figure 2 、 Figure 6 and Figure 8 , in an embodiment of the utility model, light emitting structure 1000 still includes support 3, support 3 is set with through hole 31, light source board 1 is installed at the bottom of support 3, lamp pearl 11 is set to through hole 31, light collecting part 22 is threaded in through hole 31, light collecting hole 221 is opposite to lamp pearl 11, main body 21 is installed at the top of support 3. The light 111 emitted by lamp pearl 11 directly enters light collecting part 22 through light collecting hole 221, which can reduce scattering loss and improve optical efficiency. Light source board 1, support 3 and main body 21 are directly connected by screw or buckle, so that the connection between the three is more fastened, and the risk of displacement of light source board 1 and thick wall part 2 after being vibrated is reduced.

The light shielding cavity accommodates part of light collecting part 22 in its interior, blocks the stray light interference of adjacent lamp pearl 11 through the physical boundary of cavity, thereby limiting the invalid light 111 into main light path, making the light type of main light path more pure, to meet the requirements of regulations on low beam cutoff line etc.

[0056] In an embodiment of the utility model, please refer to Figure 2 and Figure 7The light-emitting structure 1000 further comprises a decorative ring 4, the decorative ring 4 is installed on the support 3, and the decorative ring 4 is formed with a hollow area 41, the diverging surface 211 passes through the hollow area 41, so that the main body 21 is arranged in the decorative ring 4. The decorative ring 4 is used for shielding the support 3, the light source plate 1 and the like, and can also shield stray light escaping from the upper and lower directions of the main body 21, so that the overall appearance effect of the vehicle lamp can be avoided.

[0057] In an embodiment of the utility model, please refer to Figure 8 The main body 21 is connected with a positioning shaft 23, the support 3 is provided with a positioning hole 33, and the positioning shaft 23 is arranged in the positioning hole 33.
