[0038] The following is combined Figures 1 to 5 This describes the optical structure, lighting system, and carrier of the lamp according to embodiments of the present invention.
[0039] According to an embodiment of this utility model, in one aspect, a lamp optical structure is provided, including a light source assembly 1, a bracket 2, and an optical thick-walled component 3. Specifically, as... Figure 1 As shown, bracket 2 is mounted on light source assembly 1, as... Figure 3 As shown, the bracket 2 is provided with a light emission channel 201 corresponding to the light source assembly 1, and the optical thick-walled member 3 is disposed on the side of the bracket 2 facing away from the light source assembly 1. That is to say, as Figure 3As shown, the bracket 2 is located between the light source assembly 1 and the optical thick-walled component 3. On the one hand, the bracket 2 serves as a bridge connecting the light source assembly 1 and the optical thick-walled component 3, ensuring a stable connection between the various components inside the lamp. On the other hand, the light output channel 201 can control the direction and range of light propagation, which helps to reduce light leakage and scattering, and improve the utilization rate of the light source and the lighting efficiency.
[0040] At the same time, such as Figure 1 and Figure 2 As shown, the optical thick-walled component 3 has a plurality of spaced light guides 301 protruding from the side opposite to the support 2, and an opaque layer 302 is provided between each adjacent light guide 301. That is, as... Figure 3 As shown, the optical thick-walled component 3 includes a thick-walled component body 303, which is located above the support 2. Multiple light guides 301 protrude from the upper surface of the thick-walled component body 303, and an opaque layer 302 is formed between adjacent light guides 301.
[0041] In this way, the light emitted by the light source assembly 1 enters the thick-walled main body 303 through the light emission channel 201. The light guides 301 on the light-emitting side of the thick-walled main body 303 can guide the light, thereby adjusting the direction of the light emitted from the thick-walled main body 303. This ensures effective focusing of the light source in the normal direction of light emission, avoiding excessive refraction angles of the light emitted from the thick-walled main body 303 that could affect the lighting effect. It also reduces light diffusion and reflection within the thick-walled component, resulting in higher optical uniformity and better light emission. Furthermore, the opaque layer 302 effectively prevents light leakage between adjacent light guides 301, reducing light waste and avoiding glare or light pollution caused by light leakage. Thus, through the synergistic effect of the light guides 301 and the opaque layer 302, the lighting efficiency of the lamp is significantly improved, enhancing the visual effect. In addition, when not illuminated, what is visible from the outside is the convex crystal optical structure of the optical thick-walled component 3, which enhances the aesthetics of the headlights and helps improve the overall visual appeal and attractiveness of the vehicle.
[0042] Understandably, the light transmittance of the opaque layer 302 is significantly lower than that of the light guide 301, thus achieving the effect of blocking light transmission. Optionally, the opaque layer 302 can adopt a frosted surface design or a textured design to achieve the effect of blocking light. Specifically, taking the opaque layer 302 with a textured design as an example, optical thick-walled parts 3 are generally injection molded. During processing, a textured etching can be performed on the injection mold at the position corresponding to the opaque layer 302, and the injection-molded part will have a textured surface at the corresponding position.
[0043] With this configuration, the bracket 2 is placed on the light-incident side of the optical thick-walled component 3, and multiple light guides 301 are protruding on the light-emitting side of the optical thick-walled component 3. An opaque layer 302 is placed between adjacent light guides 301. This adopts an outwardly convex crystal optical structure, which achieves the purpose of optical screen segmentation and light blocking. It eliminates the traditional mesh decorative frame on the light-emitting side of the optical thick-walled component, thereby eliminating the disadvantage of a large black border area caused by the traditional use of mesh decorative frames. Moreover, it is more aesthetically pleasing when not lit, improving the user experience and enhancing product competitiveness.
[0044] Optionally, in some embodiments of this utility model, such as Figure 1 As shown, multiple light guides 301 are arranged in an array. It should be noted that the number and arrangement of the light guides 301 can be determined specifically according to design requirements such as the desired pattern or text. Specifically, the light-emitting surface of the thick-walled main body 303 is either flat or curved, and each light guide 301 is evenly distributed on the light-emitting surface of the thick-walled main body 303. Furthermore, as... Figure 2 As shown, the light guide portion 301 is square. Of course, in other embodiments, the shape of the light guide portion 301 may include, but is not limited to, a square, and may also be a rectangle, a circle, etc.
[0045] like Figure 2 As shown, along the first direction Y, the first spacing between two adjacent light guide parts 301 is L1, where 1 mm ≤ L1 ≤ 2 mm. For example, L1 can be 1 mm, 1.5 mm, 2 mm, or any value between two values; this is only an example and no specific limitation is imposed. Along the second direction X, the second spacing between two adjacent light guide parts 301 is L2, where 1 mm ≤ L2 ≤ 2 mm. For example, L2 can be 1 mm, 1.5 mm, 2 mm, or any value between two values; this is only an example and no specific limitation is imposed.
[0046] It should be noted that the first direction Y intersects with the second direction X. In this embodiment, the first direction Y is perpendicular to the second direction X. For example, the first direction Y is the width direction of the lamp's optical structure, and the second direction X is the length direction of the lamp's optical structure. Figure 1 The diagram shows only a cross-sectional view of a segment of the luminaire's optical structure along its length. Additionally, the third direction Z represents the thickness direction of the luminaire's optical structure, and the first direction Y, the second direction X, and the third direction Z are all perpendicular to each other.
[0047] This arrangement, with spacings L1 and L2, ensures that light propagation will not result in noticeable dark areas or light leakage due to excessively large gaps between the light guide sections 301. If spacings L1 and L2 are too small, such as less than 1 mm, it will be difficult to process, increasing processing difficulty and manufacturing costs; if spacings L1 and L2 are too large, such as greater than 2 mm, it will cause the black border area between adjacent light guide sections 301 to expand after illumination.
[0048] Furthermore, in some embodiments of this utility model, the light-emitting sides 3011 of multiple light guides 301 are all provided with patterned structures. Optionally, the surface patterns of the light-emitting surface are evenly distributed, which can be achieved by etching the patterned lines on the mold surface and then injection molding. Alternatively, the surface patterns of the light-emitting surface adopt a crystal-cutting-like process, by calculating the refraction and reflection angles of light, and designing a multi-faceted prism structure such as a triangle, rhombus, or pyramid shape to ensure a sparkling effect when lit, simulating the layered refraction of natural crystal and enhancing the sense of light effect layering. During processing, a five-axis CNC machining center, laser engraving, or electrical discharge machining can be used to process micron-level faceted textures on the mold surface, so that a crystal-like surface texture pattern structure is formed on the injection-molded part.
[0049] This design, by creating surface patterns on the light-emitting side 3011 of the light guide 301, can present different light effects and visual effects when lit, increasing aesthetic appeal and spatial beauty, adding design and personalized elements to the lamp, helping to meet users' diverse needs for lamp appearance, and enhancing the product's market competitiveness.
[0050] Optionally, in some embodiments of this utility model, such as Figure 3 As shown, there are multiple light-emitting channels 201, each corresponding to a different light guide 301. It should be noted that by adjusting the shape and size of the light-emitting channels 201, the light distribution and illumination effect can be optimized to meet the lighting requirements of different scenes and needs. This arrangement, through the one-to-one correspondence between the light-emitting channels 201 and the light guides 301, ensures that each light guide 301 is responsible for the light transmission and distribution in a specific area, guaranteeing that the light emitted from the light source can enter each light guide 301 more evenly and reliably, thus enhancing the light distribution and illumination effect.
[0051] Furthermore, in some embodiments of this utility model, such as Figure 3As shown, the light source assembly 1 includes multiple light-emitting elements 101 spaced apart, such as LED lights. Each of the multiple light-emitting elements 101 corresponds one-to-one with a multiple light-emitting channel 201. This arrangement ensures efficient light transmission from the light-emitting elements 101 to the light-emitting channels 201, reducing light loss during transmission, improving light utilization, and making the overall luminaire more energy-efficient. Furthermore, since each light-emitting element 101 corresponds to a light-emitting channel 201, independent control of the light in each channel can be achieved, enhancing the flexibility of the luminaire.
[0052] Optionally, in some embodiments of this utility model, see Figure 4 and Figure 5 As shown, each of the multiple light-emitting channels 201 has a recessed platform 2011 adapted to the light-emitting element 101 on the side near the light-emitting element 101. This arrangement provides sufficient assembly space for the light-emitting element 101, facilitating its installation and preventing interference between the light-emitting element 101 and the bracket 2 during assembly due to manufacturing and installation precision issues. Furthermore, during the injection molding of the bracket 2, the recessed platform 2011 prevents residual parting lines on the injection-molded parts due to the matching of the front and rear molds, thus improving the surface molding quality of the parts.
[0053] Specifically, in some embodiments of this utility model, such as Figure 3 As shown, the light source assembly 1 also includes a circuit board 102 and a heat sink 103. The circuit board 102 is connected to the bracket 2, and multiple light-emitting elements 101 are disposed on the side of the circuit board 102 near the bracket 2. The heat sink 103 is disposed on the side of the circuit board 102 away from the bracket 2. Optionally, the circuit board 102 is a printed circuit board, such as... Figure 3 As shown, multiple light-emitting elements 101 are integrated on the upper surface of the circuit board 102, and the heat sink 103 is integrated on the lower surface of the circuit board 102. The circuit board 102 and the bracket 2, as well as the bracket 2 and the optical thick-walled member 3, can be fixedly connected by screws and hot riveting structures. Alternatively, they can be fixed by snap-fit or other fixing methods.
[0054] This configuration allows the circuit board 102 to connect and support other components, and enables precise control of each light-emitting element 101. Furthermore, the heat sink 103 effectively dissipates the heat generated by the light-emitting elements 101 during operation, ensuring that the light-emitting elements 101 maintain a low temperature during operation, thereby improving their luminous efficiency and lifespan.
[0055] Optionally, in some embodiments of this utility model, such as Figure 1As shown, the optical structure of the lamp also includes a base shell 4 and an outer frame 5. The outer frame 5 is connected to the base shell 4, for example, by welding with a hot plate. As an optional implementation, it can also be fixed by screws, clips, or other fixing methods. The base shell 4 and the outer frame 5 enclose a receiving cavity 6, in which the light source assembly 1, the bracket 2, and the optical thick-walled component 3 are disposed. Specifically, as shown... Figure 3 As shown, the bracket 2 is fixedly connected to the bottom shell 4, thereby connecting the light source assembly 1, the bracket 2, the optical thick-walled component 3, and the bottom shell 4 together. Furthermore, the outer frame 5 is provided with a clearance area 501 adapted to multiple light guides 301, with the multiple light guides 301 penetrating the clearance area 501.
[0056] This design provides a stable foundation for the base shell 4, which, together with the outer frame 5, forms a mounting space to facilitate the installation of other components and ensure the protection of internal components. At the same time, the clearance zone 501 ensures that the light guide 301 can smoothly pass through the outer frame 5, achieving smooth light output, while maintaining an aesthetically pleasing overall appearance and enhancing the visual effect of the lamp.

The derivation process of this beneficial effect is largely similar to the derivation process of the beneficial effects of the above-described lighting optical structure, and therefore will not be repeated here.
[0058] According to an embodiment of the present invention, in another aspect, a vehicle is also provided, including the lighting system as described in the above embodiments. Optionally, the vehicle is a vehicle, a low-altitude aircraft, etc. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the above-described lighting system, and therefore will not be repeated here.
[0059] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
