[0007] In some embodiments, in a direction perpendicular to the surface of the circuit board, the light guide surface and the inner lens are spaced apart by a distance d1, where d1 satisfies: 0.2mm≤d1≤0.8mm.

[0008] In some embodiments, the light source includes a lamp substrate and a light guide portion.

[0014] The bottom wall of the first lamp trough includes a smooth area, and the smooth area and the surface of the support portion enclose the main lamp trough to form the main lamp trough. A portion of the light source is disposed in the main lamp trough.

[0015] The bottom wall of the first lamp trough also includes at least one recessed area, and each of the recessed areas encloses a sub-lamp trough, with another part of the light source disposed in the sub-lamp trough.

[0016] In some embodiments, the inner lens further includes a first mating portion disposed on the support portion, and the module decorative frame further includes a second mating portion disposed on the circuit board.

[0047] A. First direction; B. Second direction. Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0049] The inventors discovered that the lighting module of a vehicle headlight is usually tightly attached to the surrounding decorative frame, with a very small gap between the decorative frame and the lighting module. This makes it impossible to arrange ambient lighting on the decorative frame, limiting the improvement of the lighting effect around the lighting module. Based on this, this application provides a decorative frame and a vehicle headlight.

[0050] like Figure 1 The diagram shown is a three-dimensional structural schematic of a vehicle headlight 1 according to an embodiment of this application. The headlight 1 can be a headlight 1 for emitting light towards the front of the vehicle, or it can be a headlight 1 for emitting light towards the rear of the vehicle. The headlight 1 includes a lighting module 10, which can be a high beam lighting module for emitting high beam light, a low beam lighting module for emitting low beam light, or a high and low beam lighting module capable of emitting both high beam and low beam light. The low beam light emitted by the headlight 1 is mainly used for road lighting in urban areas, intersections, and when two vehicles meet, while the high beam light emitted by the headlight 1 is mainly used for road lighting on highways, in suburban areas, and in situations with poor lighting conditions.

[0051] like Figure 2 As shown, the headlight 1 also includes a module decorative frame 20, which encloses a receiving cavity and an illumination opening 101 communicating with the receiving cavity. The illumination module 10 is disposed within the receiving cavity, and the light-emitting surface 11 of the illumination module 10 faces the illumination opening 101 or is disposed within the illumination opening 101, so that the light emitted by the illumination module 10 can be smoothly emitted from the illumination opening 101. The module decorative frame 20 is used to provide protection for the illumination module 10, and at the same time, it serves to decorate the appearance of the headlight 1.

[0052] To ensure a compact overall structure for the headlight 1, the gap between the module decorative frame 20 and the side wall of the lighting module 10 is small. Installing a light-generating structure within this confined space is challenging due to space constraints and increased assembly difficulty. This application improves the structure of the module decorative frame 20. After assembly, in addition to the lighting module 10, the portion of the headlight 1 located on the side of the lighting module 10 also generates light, improving the headlight 1's illumination effect.

[0053] like Figure 3 As shown, the module decorative frame 20 includes a decorative body 100 and an ambient light assembly 200. The decorative body 100 is used to surround the outer periphery of the lighting module 10 of the vehicle headlight 1. The ambient light assembly 200 is installed on the decorative body 100, and the ambient light assembly 200 and the decorative body 100 together form a receiving cavity, and the decorative body 100 forms a lighting opening 101.

[0054] like Figure 3 As shown, the decorative body 100 includes at least one first sidewall 110 facing the sidewall of the lighting module 10. The first sidewall 110 is set at an angle to the light-emitting surface 11 of the lighting module 10. Each first sidewall 110 has at least one ambient opening 111. The light generated by the ambient light assembly 200 can be emitted through the ambient opening 111 so that when the ambient light assembly 200 generates light, the side of the headlight 1 can present a luminous effect.

[0055] Combination Figure 3 and Figure 4 The ambient lighting assembly 200 includes a circuit board 230, a light source 210, and an inner lens 220. The light source 210 and the inner lens 220 are located on the same side of the circuit board 230, and the circuit board 230, the light source 210, and the inner lens 220 are stacked sequentially in a direction Y perpendicular to the surface of the circuit board 230. The light source 210 is mounted on the circuit board 230 and electrically connected to it to receive electrical energy transmitted from the circuit board 230 to generate light. The inner lens 220 is located on the first sidewall 110 corresponding to the lighting opening 101, and is used to guide the light generated by the light source 210 to be emitted from the ambient lighting opening 111.

[0056] In this embodiment, the ambient lighting assembly 200 includes at least one light source 210. Optionally, the ambient lighting assembly 200 includes one light source 210, and the first sidewall 110 has one or more ambient openings 111, through which light generated by the light source 210 passes through the inner lens 220 and exits from the one or more ambient openings 111 of the first sidewall 110. Optionally, the ambient lighting assembly 200 includes multiple light sources 210, and the first sidewall 110 has multiple ambient openings 111 corresponding one-to-one with the multiple light sources 210 of the ambient lighting assembly 200, through which light generated by each light source 210 exits from the corresponding ambient opening 111.

[0057] In the direction Y perpendicular to the surface of the circuit board 230, one part of the inner lens 220 is sandwiched between the circuit board 230 and the first sidewall 110, and the other part of the inner lens 220 is located at the ambient opening 111. In this embodiment, the ambient light assembly 200 is integrated and installed on the decorative body 100. The inner lens 220 is clamped and positioned by the circuit board 230 and the first sidewall 110. There is no need to set other structures to limit the position of the inner lens 220. The structure is simple and helps to reduce the volume of the ambient light assembly 200.

[0058] The light source 210 has a light guide surface 213. The light source 210 is configured to emit continuous light from the light guide surface 213. That is, when the continuous light emitted by the light source 210 is observed by an external observer, the light guide surface 213 can present a lighting effect of being continuously lit without any shadow.

[0059] It is understandable that when the light source 210 uses multiple spaced LEDs, in order to present a continuous light emission effect, it is generally necessary to perform light homogenization processing on the multiple light sources 210. For example, the inner lens 220 is set to have a light homogenization effect to homogenize the light generated by the multiple LEDs. In this case, the inner lens 220 with the light homogenization effect needs to be far away from the light source 210 in order to achieve a good effect of eliminating the light and shadow of the LEDs. However, this light emission method results in a large distance between the light source 210 and the inner lens 220, which in turn results in a large size of the ambient light assembly 200, which is not conducive to installing the ambient light assembly 200 in a small space.

[0060] This embodiment selects a light source 210 capable of directly emitting continuous light, eliminating the need for subsequent light homogenization by the inner lens 220. This reduces the distance between the light source 210 and the inner lens 220, effectively minimizing the size of the ambient light assembly 200. During assembly, only a suitable assembly gap between the light guide surface 213 and the inner lens 220 needs to be considered to prevent collisions between the light guide surface 213 and the inner lens 220 during vehicle vibration. This maximizes the reduction of the gap between the light guide surface 213 of the light source 210 and the inner lens 220, making it ideal for installing the ambient light assembly 200 in confined spaces.

[0061] In some embodiments, the light guide surface 213 of the light source 210 and the wall surface of the inner lens 220 are spaced apart by a distance d1, where d1 satisfies: 0.2mm≤d1≤0.8mm. For example, d1 can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.8mm, or any range of the above. This assembly interval range is an effective safety interval range, preventing the light guide surface 213 of the light source 210 from having rigid contact with the wall surface of the inner lens 220, which could cause assembly stress or collisions. At the same time, it can also make the assembly structure of the circuit board 230, the light source 210, and the inner lens 220 compact, preventing the ambient light assembly 200 from having an excessively large Y dimension in the direction perpendicular to the surface of the circuit board 230.

[0062] like Figure 5As shown, each light source 210 includes a lamp substrate 211 and a light guide portion 212. The lamp substrate 211 has at least one light-emitting portion 214. The lamp substrate 211 is connected to the circuit board 230 to receive the light transmitted by the circuit board 230, thereby causing the light-emitting portion 214 to generate light. The light guide portion 212 is disposed on the lamp substrate 211 and covers the light-emitting portion 214. The light guide portion 212 has a light guide surface 213. The light guide portion 212 is used to conduct the light generated by the light-emitting portion 214 and emit the light from the light guide surface 213 to the inner lens 220. Optionally, the light guide 212 is used to homogenize the light generated by the light-emitting part 214 so that the light is emitted from the light guide surface 213; or, the light-emitting part 214 is in the form of a continuous sheet, and the light-emitting part 214 itself can emit continuous light. In this case, the light guide 212 may not have a homogenizing effect. The light guide 212 is only used to deflect the light generated by the light-emitting part 214 so that the light is emitted from the light guide surface 213 at a suitable angle.

[0063] In some embodiments, the light source 210 is a strip light source. Correspondingly, the lamp substrate 211 is elongated, and the light-emitting part 214 extends along the length direction of the lamp substrate 211, with the light guide part 212 covering the light-emitting part 214. Optionally, the ambient light assembly 200 includes multiple strip light sources, which are arranged side-by-side along a direction forming an angle with the length direction of the strip light source; or, the multiple strip light sources may also be arranged side-by-side along the length direction of the strip light source. The above is only an exemplary description of the arrangement of multiple strip light sources. The embodiments of this application do not limit the arrangement of multiple strip light sources, and the specific arrangement can be selected according to actual needs.

[0064] In some embodiments, the light source 210 may also be configured in other shapes. For example, the light-emitting portion 214 of the light source 210 may be circular, and correspondingly, the light guide portion 212 may be circular and cover the light-emitting portion 214; or, the light-emitting portion 214 may be rhomboid, and correspondingly, the light guide portion 212 may be rhomboid and cover the light-emitting portion 214. Of course, in some other embodiments, the light-emitting portion 214 may also be configured in other shapes to enrich the effect of the side of the headlight 1 being illuminated. Regarding the shape of the light-emitting portion 214, this application embodiment does not limit it in this regard, and the specific shape can be selected according to actual needs.

[0065] In some embodiments, the inner lens 220 has a first lamp groove 224 on the surface facing the circuit board 230, and the light source 210 is mounted on the circuit board 230. At least a portion of the light source 210 is disposed in the first lamp groove 224. By providing the inner lens 220 with a first lamp groove 224 capable of accommodating the light source 210, it not only helps to further reduce the volume of the ambient light assembly 200, but also allows the inner lens 220 to define that the walls of the first lamp groove 224 can be used to receive the light generated by the light source 210. Furthermore, by designing the surface shape of the walls of the first lamp groove 224, the inner lens 220 can deflect the light generated by the light source 210, thereby improving the light output effect of the ambient light assembly 200.

[0066] like Figure 6 As shown, the inner lens 220 includes a lens body 221 and multiple support portions 222. The multiple support portions 222 protrude from the surface of the lens body 221 facing the circuit board 230 and are in contact with the circuit board 230. The lens body 221 and the multiple support portions 222 together form a first lamp groove 224. Light generated by the light source 210 can enter the inner lens 220 from the surface of at least one of the lens body 221 and the multiple support portions 222. In the direction Y perpendicular to the surface of the circuit board 230, the light source 210 is disposed between the lens body 221 and the circuit board 230. The multiple support portions 222 provide support for the lens body 221, so that the inner lens 220 can be stably mounted on the circuit board 230.

[0067] In some embodiments, such as Figure 6 As shown, the first light trough 224 includes a main light trough 2241 and at least one sub-light trough 2242. A portion of the light source 210 is disposed in the main light trough 2241, and another portion of the light source 210 is disposed in the sub-light trough 2242. Specifically, the bottom wall of the first light trough 224 includes a smooth area, which, together with the surface of the support portion 222, forms the main light trough 2241. The bottom wall of the first light trough 224 also includes at least one recessed area, which together form a sub-light trough 2242. Thus, by providing the sub-light trough 2242 to further accommodate a portion of the light source 210, the size of the ambient light assembly 200 can be further reduced in the direction Y perpendicular to the surface of the circuit board 230.

[0068] Optionally, when the ambient lighting assembly 200 includes one light source 210, the first light trough 224 may correspondingly include one sub-light trough 2242. Optionally, when the ambient lighting assembly 200 includes multiple light sources 210, the first light trough 224 may include multiple sub-light troughs 2242, with the multiple light sources 210 correspondingly disposed in the multiple sub-light troughs 2242, so that the light generated by each light source 210 enters the inner lens 220 through the wall of the corresponding sub-light trough 2242, so as to meet the light output requirements of different light sources 210.

[0069] Furthermore, when a portion of the light source 210 is disposed within the sub-lamp trough 2242, at least a portion of the wall surface of the sub-lamp trough 2242 covers the light guide surface 213 of the light source 210 in the direction Y perpendicular to the surface of the circuit board 230, so that the wall surface of the sub-lamp trough 2242 can more fully receive the light generated by the light source 210, thereby improving the light utilization rate. For example, in the direction parallel to the surface of the circuit board 230, the width of the sub-lamp trough 2242 is greater than the width of the light guide surface 213 of the light source 210, and thus, in the direction Y perpendicular to the surface of the circuit board 230, the wall surface of the sub-lamp trough 2242 can completely cover the corresponding light guide surface 213 of the light source 210.

[0070] The wall surface of the sub-light trough 2242 can be configured to have a shape similar to the light guide surface 213 of the light source 210. For example, when the light guide surface 213 of the light source 210 is flat, the bottom wall surface of the sub-light trough 2242 is correspondingly configured to be flat; when the light guide surface 213 of the light source 210 is arc-shaped, the wall surface of the sub-light trough 2242 is correspondingly configured to be arc-shaped. Regarding the bottom wall surface of the main light trough 2241, when the bottom wall surface of the main light trough 2241 is set towards the surface of other parts of the light source 210, it is configured to have a shape similar to the surface of the corresponding light source 210; when the bottom wall surface of the main light trough 2241 is set towards the surface of the circuit board 230, it is configured to have a shape similar to the surface of the corresponding circuit board 230, so as to fit the shape of the surface of other parts of the light source 210 or the surface of the circuit board 230, resulting in a compact structure and reducing the volume of the ambient light assembly 200 in the direction Y perpendicular to the surface of the circuit board 230.

[0071] In some embodiments, in the direction Y perpendicular to the board surface of the circuit board 230, the wall of the main light groove 2241 is spaced apart from its corresponding surface, and the distance is d2, where d2 satisfies: d2≥d1, 0.3mm≤d2≤1.0mm, which also prevents the wall of the main light groove 2241 from contacting the surface of other structures, so that the wall of the main light groove 2241 has a safe distance from the surface of other structures.

[0072] In some other embodiments, the bottom wall of the first light trough 224 is a smooth surface, such as a smooth plane or a smooth arc surface. That is, the first light trough 224 may only include the main light trough 2241 and not the sub-light trough 2242. The light source 210 is disposed in the main light trough 2241, and there is no case where the light source 210 is disposed in the sub-light trough 2242. In this case, when the ambient light assembly 200 includes multiple light sources 210, all multiple light sources 210 are disposed in the main light trough 2241.

[0073] The light source 210 is sandwiched between the lens body 221 and the circuit board 230, such as Figure 8 and Figure 9As shown, in some embodiments, the surface of the circuit board 230 facing the inner lens 220 is provided with at least one second lamp groove 231, and a portion of the light source 210 is disposed in the second lamp groove 231. By providing the second lamp groove 231 to accommodate the light source 210, the size of the ambient light assembly 200 can be further reduced in the direction Y perpendicular to the surface of the circuit board 230. The side wall and bottom wall of the second lamp groove 231 are in contact with the surface of the light source 210, so that the second lamp groove 231 can also restrict the position of the light source 210 and improve the installation stability of the light source 210.

[0074] When the circuit board 230 does not include the second lamp slot 231, the first lamp slot 224 where the inner lens 220 is provided includes a main lamp slot 2241 and a sub-lamp slot 2242. The lamp substrate 211 is disposed on the surface of the circuit board 230 and housed in the main lamp slot 2241, and the light guide 212 is disposed in the sub-lamp slot 2242. Alternatively, the first lamp slot 224 where the inner lens 220 is provided only includes the main lamp slot 2241. The lamp substrate 211 is disposed on the surface of the circuit board 230, and both the lamp substrate 211 and the light guide 212 are housed in the main lamp slot 2241.

[0075] When the circuit board 230 includes the second lamp slot 231, such as Figure 9 As shown, the first lamp slot 224 for which the inner lens 220 can be installed includes a main lamp slot 2241 and a sub-lamp slot 2242. The lamp substrate 211 is disposed in the second lamp slot 231. One part of the light guide 212 is disposed in the main lamp slot 2241 and the other part is disposed in the sub-lamp slot 2242. Alternatively, the first lamp slot 224 for which the inner lens 220 is installed includes only the main lamp slot 2241, the lamp substrate 211 is disposed in the second lamp slot 231, and the light guide 212 is disposed in the main lamp slot 2241.

[0076] When the circuit board 230 includes a second lamp slot 231, the second lamp slot 231 also facilitates quick positioning of the installation position of the light source 210, improving assembly efficiency. In some embodiments, the inner lens 220 further includes a first mating portion 241 disposed on the support portion 222, and the module decorative frame 20 further includes a second mating portion 242 disposed on the circuit board 230. The first mating portion 241 and the second mating portion 242 are configured to quickly position the installation position of the inner lens 220 and the light source 210, so that the light generated by the light source 210 can enter the inner lens 220 at a suitable position.

[0077] Optionally, the first mating part 241 and the second mating part 242 are inserted into each other in a Y-direction perpendicular to the surface of the circuit board 230 to quickly align and install the inner lens 220 onto the circuit board 230. Alternatively, the first mating part 241 and the second mating part 242 are snap-fitted together to directly install the inner lens 220 onto the circuit board 230. For example, as shown... Figure 10As shown, one of the first mating part 241 and the second mating part 242 is a mating protrusion and the other is a mating groove. The mating protrusion can be inserted into the mating groove to achieve an insertion fit, or the mating protrusion can be disposed in the mating groove and the two are interference-fitted to achieve a snap-fit ​​fit. For example, one of the first mating part 241 and the second mating part 242 is a mating hook and the other is a mating slot. The mating hook and the mating slot engage to achieve a snap-fit ​​fit.

[0078] In some embodiments, the circuit board 230 and the inner lens 220 are integrally disposed. Optionally, the first mating part 241 and the second mating part 242 are fitted together, and the gap between the first mating part 241 and the second mating part 242 is filled with adhesive to bond and fix the first mating part 241 and the second mating part 242. Optionally, the gap between the circuit board 230 and the support part 222 may also be filled with adhesive to bond the support part 222 and the circuit board 230 together.

[0079] In some embodiments, the circuit board 230 and the light source 210 are integrally disposed. Optionally, when the circuit board 230 has a second lamp groove 231, the gap between the surface of the lamp substrate 211 of the light source 210 and the wall of the second lamp groove 231 can be filled with adhesive. Optionally, when the circuit board 230 has a second lamp groove 231, the lamp substrate 211 is disposed in the second lamp groove 231, or the lamp substrate 211 can be snap-fitted onto the circuit board 230, or the lamp substrate 211 can be mounted onto the circuit board 230 using screws.

[0080] A first mating part 241 and a second mating part 242 that mates with the first mating part 241 constitute a mating unit. The module decorative frame 20 has multiple mating units, with adjacent mating units spaced apart to increase the contact area and improve the assembly stability of the circuit board 230 and the inner lens 220. In some embodiments, in a first direction A or a second direction B parallel to the surface of the circuit board 230, the first direction A, the second direction B, and the direction Y perpendicular to the surface of the circuit board form an angle with each other. Some mating units are located on one side of the first lamp groove 224, and other mating units are located on the other side of the first lamp groove 224; or, multiple mating units are located on opposite sides of the first lamp groove 224 in the first direction A, and the remaining multiple mating units are located on opposite sides of the first lamp groove 224 in the second direction B. For example, when the ambient light assembly 20 includes multiple strip light sources, the length direction of the multiple strip light sources is parallel to the first direction A, and the multiple strip light sources are arranged side by side along the second direction B. The number of mating units is two sets. In the second direction B, one set of mating units is located on one side of the first light groove 224, and the other set of mating units is located on the other side of the first light groove 224. The inner lens 220 is fastened to the circuit board 230, which enables the two to be quickly aligned and is easy to assemble.

[0081] In some embodiments, the inner lens 220 includes at least one light-emitting portion 223, which protrudes from the surface of the lens body 221 away from the support portion 222. Each light-emitting portion 223 is disposed within one of the atmosphere openings 111, and the surface of the lens body 221 away from the support portion 222 is in contact with the surface of the first sidewall 110. Wherein, the light-emitting portion 223 disposed within the atmosphere opening 111, and the surface of the light-emitting portion 223 away from the lens body 221 can smoothly transition with the outer surface of the first sidewall 110; alternatively, a portion of the light-emitting portion 223 is disposed within the atmosphere opening 111, and another portion of the light-emitting portion 223 extends beyond the outer surface of the first sidewall 110, i.e., another portion of the light-emitting portion 223 protrudes from the outer surface of the first sidewall 110.

[0082] In some embodiments, an adhesive can be filled in the gap between the surface of the lens body 221 facing away from the support portion 222 and the surface of the first sidewall 110 to bond the inner lens 220 body to the surface of the first sidewall 110, so that the inner lens 220 is integrally formed with the decorative body 100. In some embodiments, an adhesive can be provided in the gap between the surface of the light-emitting portion 223 and the wall of the atmosphere opening 111 to bond the light-emitting portion 223 to the first sidewall 110; alternatively, a sealing structure can be provided in the gap between the surface of the light-emitting portion 223 and the wall of the atmosphere opening 111 for sealing and waterproofing.

[0083] In this embodiment, during assembly, the circuit board 230, light source 210, and inner lens 220 of the ambient light component 200 can be assembled into one unit first, and then the ambient light component 200 can be installed on the decorative body 100. The decorative body 100 and the ambient light component 200 together form a receiving cavity. Finally, the module decorative frame 20 is sleeved on the periphery of the lighting module 10, so that the surface of the circuit board 230 contacts the side wall of the lighting module 10. The ambient light component 200 is sandwiched between the side wall of the lighting module 10 and the wall of the first side wall 110, which limits the position of the ambient light component 200. This allows the ambient light component 200 to be installed in a small space, and the assembly method is simple.

[0084] In some embodiments, at least one of the light-emitting portion 223 of the inner lens 220 and the lens body 221 is used to homogenize the light, thereby further improving the light emission effect through the inner lens 220. Optionally, the lens body 221 is used to homogenize the light, and the lens body 221 is made of a homogenizing material; or, the wall surface of the first lamp slot 224 defined by the lens body 221 is provided with microstructures capable of homogenizing the light. Optionally, the light-emitting portion 223 is used to homogenize the light, and the light-emitting portion 223 is made of a homogenizing material; or, the surface of the light-emitting portion 223 is provided with microstructures capable of homogenizing the light. In this application embodiment, the material of the inner lens 220 is not limited; any material or structure in the art that has a homogenizing effect on light is applicable to this application.

[0085] Since the light guide surface 213 of the light source 210 of this application can emit continuous light, in some embodiments, the inner lens 220 can be made of a light-transmitting material, and the inner lens 220 can be a transparent lens, that is, the light-emitting part 223 and the lens body 221 of the inner lens 220 do not have a uniform light effect. At this time, except for the deflection that occurs when light propagates in different media, the inner lens 220 can be selected to not have a deflection effect on light. The surface shape of the bottom wall of the first lamp slot 224 of the inner lens 220 and the surface shape of the light-emitting part 223 can also be designed so that the light is deflected when it passes through the bottom wall of the first lamp slot 224 and the surface of the light-emitting part 223, so that the light is emitted at a suitable angle, for example, so that the light is emitted at an angle that is obliquely upward or horizontal, so that an external observer can observe the light-emitting part 223 being lit from a top-down or horizontal perspective. In addition, the inner lens 220 can be a colored transparent lens to make the ambient opening 111 present a richly colored lighting effect. For example, the inner lens 220 can be a transparent lens such as red, green or yellow.

[0086] In some embodiments, the decorative body 100 includes a first sidewall 110, which encloses and forms an annular structure. The first sidewall 110 may include a plurality of spaced ambient light areas, each of which has at least one ambient opening 111. The modular decorative frame 20 includes a plurality of ambient light components 200 that correspond one-to-one with the plurality of ambient light areas, so that the modular decorative frame 20 can present the effect of multiple areas being lit.

[0087] In some embodiments, such as Figure 11 As shown, the decorative body 100 includes a plurality of first sidewalls 110 and a plurality of second sidewalls 120. The first sidewalls 110 are provided with air vents 111, while the second sidewalls 120 are not provided with air vents 111. The plurality of first sidewalls 110 and the plurality of second sidewalls 120 are alternately arranged, with adjacent first sidewalls 110 and second sidewalls 120 arranged at an angle. Each first sidewall 110 is provided with at least one air vent 111. For example, as... Figure 11 As shown, the decorative body 100 includes two second sidewalls 120 arranged opposite each other along the vertical direction of the headlight 1, and two first sidewalls 110 arranged opposite each other along the horizontal direction of the headlight 1. The direction Y perpendicular to the surface of the circuit board 230 can be at an angle or parallel to the horizontal direction of the headlight 1, the first direction A can be at an angle or parallel to the front-rear direction of the headlight, and the second direction B can be at an angle or parallel to the vertical direction of the headlight. At this time, two sets of ambient light components 200 are provided corresponding to the two first sidewalls 110 of the decorative body 100, which can make the left and right sides of the headlight 1 appear lit.

[0088] In some embodiments, the decorative body 100 includes a decorative head 130 and a decorative tail 140, which are respectively disposed on opposite sides of the first sidewall 110 in the second direction B. The decorative head 130 encloses and forms an illumination opening 101, and the decorative tail 140 encloses and forms a mounting opening. The headlight 1 may also include a radiator, which can be mounted on the decorative tail 140 corresponding to the mounting opening to dissipate heat from the illumination module 10. For example, Figure 12 As shown, in the direction from the decorative head 130 to the decorative tail 140, the first sidewall 110 gradually tilts away from the lighting module 10. Correspondingly, the ambient opening 111 also tilts away from the lighting module 10. At this time, the first direction A can form an angle with the front-rear direction of the headlight. Thus, when the ambient light assembly 200 generates light, an external observer can not only observe the first sidewall 110 being lit up from the left or right side of the headlight 1, but also observe the first sidewall 110 being lit up from the front side of the headlight 1.
