Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, and specifically to a thick-walled component for automotive lighting. Background Technology

[0002] In the field of automotive lighting, thick-walled components are key optical elements in vehicle lights and signal lights, and are widely used in daytime running lights, turn signals, brake lights and position lights. These components are usually made of transparent PC / PMMA plastic material through injection molding and have excellent optical properties.

[0003] However, when the headlight housing has an irregular or curved shape, traditional thick-walled component designs often use a stepped structure for adaptation. This requires the PCB to be designed to fit the thick-walled component, such as... Figure 1 As shown, a PCBA is made by bonding stepped aluminum plates with an FPC flexible board (3). This type of PCBA requires the use of FPC and stepped aluminum plates and a stepped design, which increases the design complexity of the PCBA and leads to an increase in manufacturing costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a thick-walled automotive lamp component that reduces material costs through optimized design.

[0005] To address the above problems, the present invention provides the following technical solution:

[0006] A thick-walled component for automotive lights, comprising:

[0007] A lens with an entrance port for light;

[0008] The substrate, at least on the side facing the lens, is designed to be planar;

[0009] LED beads are located on the side of the substrate facing the lens, and the LED beads are electrically connected to the substrate;

[0010] The LED beads are movable relative to the lens and can be aligned with the light inlet by the displacement, so that the light from the LED beads is concentrated into the light inlet and emitted outward from the other side of the lens.

[0011] In one embodiment, the thick-walled component of the vehicle lamp includes an extension rod disposed between the light inlet of the lens and the substrate. The LED lamp bead is mounted on the extension rod and moves closer to or further away from the light inlet by extending and retracting the extension rod.

[0012] In one embodiment, the extension rod is mounted on the substrate;

[0013] Alternatively, the extension rod may be mounted on the lens;

[0014] Alternatively, the extension rod may be located between the substrate and the lens and be assembled and connected to the substrate and the lens.

[0015] In one embodiment, the extension rod includes a fixing rod mounted on the substrate, and the LED beads are mounted on the top end of the extension rod.

[0016] In one embodiment, the extension rod includes a telescopic rod and a support rod, with the extension rod disposed between the telescopic rods. The telescopic rod is used to connect the substrate and / or the lens, and the support rod is used to mount the LED beads.

[0017] In one embodiment, the telescopic rod includes a first rod body and a second rod body. The first rod body is installed inside the second rod body, and one end of the second rod body is fixed to the base plate. The first rod body is provided with a limiting buckle for limiting the second rod body. The limiting buckle moves on the first rod body so that the second rod body can be movable or fixed relative to the first rod body.

[0018] In one embodiment, the telescopic rod includes a sleeve rod and a compression rod and a spring installed within the sleeve rod. The spring is installed on the compression rod and connected to one end of the compression rod, and the spring abuts against the support rod within the sleeve rod. One end of the compression rod is fixed to the support rod, and the spring applies an elastic force to the support rod to compress or extend the compression rod.

[0019] In one embodiment, the telescopic rod includes a sleeve rod and a compression rod and a spring installed within the sleeve rod. The spring is installed on the compression rod and connected to one end of the compression rod, and the spring abuts against the support rod within the sleeve rod. One end of the compression rod is fixed to the support rod, and the spring applies an elastic force to the support rod to compress or extend the compression rod.

[0020] In one embodiment, the thick-walled component of the vehicle lamp further includes a ball joint, which is mounted on one end of the telescopic rod near the light inlet, and the LED lamp bead is mounted on the ball joint.

[0021] In one embodiment, there are multiple light inlets, the number of LED beads corresponds to the number of light inlets, and each LED bead is supported by a ball joint and abuts against the periphery of the light inlet or is spaced apart from the light inlet.

[0022] The beneficial effects of this invention are: by adjusting the position of the LED beads, the LED beads can be displaced, and by displacement, the LED beads are aligned with the light entrance of the lens, thereby concentrating the light into the lens from the light entrance. This allows the thick-walled component of the vehicle lamp to achieve the required optical performance based on the planar design of the substrate, thereby reducing the overall design cost of the thick-walled component of the vehicle lamp and improving the simplicity of the thick-walled component of the vehicle lamp.

Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] Please refer to Figure 3-10 As shown, this embodiment provides a thick-walled component 100 for a vehicle lamp, comprising: a lens 110, a substrate 111, and LED beads 112. The lens 110 reflects and refracts light 100a to increase the light intensity of the light 100a. In this embodiment, the lens 110 has a light inlet 11a for receiving light 100a from the LED beads 112 and processing the light 100a through its internal structure. Furthermore, in this embodiment, the side of the substrate 111 facing the lens 110 is designed as a plane, and the LED beads 112... 12 is located on the side of substrate 111 facing lens 110. LED bead 112 is electrically connected to substrate 111. By connecting substrate 111, current can be transmitted through substrate 111 to LED bead 112, causing it to emit light. Furthermore, LED bead 112 can be displaced relative to lens 110, so that it can move closer to or further away from lens 110. It can also be aligned with light inlet 11a by displacement, so that the light 100a of LED bead 112 is concentrated into light inlet 11a and emitted outward from the other side of lens 110.

[0038] Understandably, when the headlight housing has an irregular or curved shape, traditional thick-walled component designs often use a stepped structure for adaptation. This necessitates a PCB design to accommodate the thick-walled component. Thick-walled components are typically designed with two structures: one is... Figure 1 As shown, a PCBA is made by bonding stepped aluminum sheets with an FPC flexible board. Furthermore, because it is necessary to combine FPC with stepped aluminum sheets to manufacture PCBAs, another method is... Figure 2 As shown, make all TIR condenser cups flat ( Figure 2 In order to lay out LEDs, the former method increases the design complexity of the PCB, resulting in higher manufacturing costs, while the latter method results in thick-walled components, lenses with excessive height and weight, leading to high material costs.

[0039] The key design feature of this embodiment lies in the adjustable position of the LED beads 112, allowing them to move closer to or further away from the lens 110. When the LED beads 112 are adjusted to be closer to the lens 110, they can be more accurately aligned with the light entrance 11a of the lens 110, thus concentrating the emitted light 100a into the lens 110. After processing by the internal structure of the lens 110, this light 100a exits from the other side of the lens 110. It is understood that by designing the LED beads 112 to be adjustable, the substrate 111 can be designed as a flat surface, avoiding the need for the substrate 111 to match the curved surface structure of the lens 110 (resulting in a stepped structure) or for the lens 110 to match the LED beads (resulting in a flush structure at the light entrance 11a near the substrate 111), both of which increase design and production costs. Furthermore, it improves the simplicity and reliability of the thick-walled component 100 of the vehicle lamp. With this structural design, the entire vehicle lamp system can flexibly adjust the position of the light source within different types of vehicle lamp housings, thus adapting to different types of vehicle lamps to achieve the required optical performance.

[0040] Optionally, in this embodiment, the position adjustment of the LED bead 112 is achieved through a specific mechanical mechanism, such as an extension rod 113.

[0041] Based on the above plan, please refer to Figure 3-7As shown, in this embodiment, the LED bead 112 is positioned on the side of the substrate 111 facing the lens 110, and is electrically connected to the substrate 111. The LED bead 112 operates by transmitting current through the substrate 111. Furthermore, through further design, the LED bead 112 can be displaced relative to the substrate 111, allowing it to move to the position of the light inlet 11a when it approaches the lens 110, and align with the light inlet 11a. This allows the light 100a from the LED bead 112 to be concentrated into the light inlet 11a and emitted outward from the other side of the lens 110. This structure, by designing the LED bead 112 to move on the side of the substrate 111 facing the lens 110, allows the LED bead 112 to be moved to the position of the light inlet 11a and aligned with the light inlet 11a during assembly. This allows the side of the substrate 111 facing the lens 110 to be designed as a plane, thereby simplifying the design of the PCB and reducing the design and production costs of thick-walled components.

[0042] It is understandable that the substrate 111 in this embodiment is a PCB board.

[0043] Please refer to Figure 3-4 and Figure 8-9 As shown, preferably, the lens 110 is provided with a light-emitting mirror 1111 for the light 100a to be emitted outward. The light-emitting mirror 1111 is located on the side of the lens 110 away from the light inlet 11a. It can be understood that after the light 100a of the LED lamp bead 112 enters the lens 110 through the light inlet 11a, it is reflected and refracted within the lens 110, and then emitted outward from the light-emitting mirror 1111. In this embodiment, the light-emitting mirror 1111 is designed as a structure of multiple block-shaped reflective mirrors to improve the light emission effect of the light-emitting mirror 1111.

[0044] Please refer to Figure 6-9 As shown, according to the above scheme, preferably, the thick-walled component 100 of the vehicle lamp includes an extension rod 113. The thick-walled component 100 of the vehicle lamp achieves dynamic adjustment of the position of the LED lamp bead 112 relative to the light inlet 11a of the lens 110 by introducing the extension rod 113. In this technical solution, the extension rod 113 is disposed between the light inlet 11a of the lens 110 and the substrate 111, and serves as a support structure to support the LED lamp bead 112.

[0045] Please refer to Figure 4-5As shown, in some preferred embodiments, the extension rod 113 includes a fixing rod 210, which is mounted on the substrate 111. The LED beads 112 are mounted on the top of the extension rod 113. In this embodiment, the fixing rod 210 is fixedly mounted on the substrate 111. By designing the distance from the top of the fixing rod 210 to the light inlet 11a, the LED beads 112 can be directly aligned with the light inlet 11a when they are mounted on the top of the fixing rod 210.

[0046] Understandably, the extension rod 113 can extend and retract axially to approach or move away from the light inlet 11a, thereby driving the LED beads 112 fixed thereon to move. When it is necessary to adjust the position of the LED beads 112, the extension rod 113 can be extended or shortened to allow the LED beads 112 to approach or move away from the light inlet 11a of the lens 110. In some embodiments, the extension rod 113 can be a mechanical device including an inner and outer sleeve structure, wherein the inner rod can slide inside the outer rod to achieve a change in length. In other embodiments, the extension rod 113 adopts a combination of a spring 412 and a compression rod 411, using the elastic force of the spring 412 to drive the extension and retraction of the compression rod 411.

[0047] Understandably, regardless of the method used, the extension rod 113 must ensure sufficient rigidity and stability to ensure that the LED bead 112 maintains the correct posture in any position and does not shift due to external vibrations or other factors. Furthermore, the extension rod 113 can be electrically connected to the LED bead 112 by making its body a conductor, thus electrically connecting the LED bead 112 to the substrate 111, or by threading wires through the extension rod 113 to electrically connect the LED bead 112 to the substrate 111, thereby enabling operation. In addition, the extension rod 113 needs to fit tightly with the substrate 111 and any possible lens 110 components to ensure the compactness and reliability of the overall structure. Through this design, the LED bead 112 can be precisely positioned according to actual needs to achieve the most favorable position for the concentrated light 100a to enter the light inlet 11a of the lens 110.

[0048] In this technical solution, the extension rod 113 is designed to provide multiple installation methods to adapt to different structural requirements. Specifically, in some embodiments, the extension rod 113 is directly mounted on the substrate 111, which allows the LED bead 112 to move relative to the lens 110 while maintaining a stable electrical connection with the substrate 111. In this configuration, one end of the extension rod 113 is fixed to the substrate 111, while the other end can extend and retract freely, thereby moving the LED bead 112 closer to or further away from the lens 110. In other embodiments, the extension rod 113 is designed to be mounted on one side of the lens 110. This arrangement allows the LED bead 112 to move from the side of the lens 110 toward the substrate 111. In this way, one end of the extension rod 113 is fixed inside or at the edge of the lens 110, while the other end is connected to the LED bead 112, allowing the LED bead 112 to move along the axial direction of the extension rod 113, thereby adjusting its position relative to the light entrance 11a. In a third embodiment, the extension rod 113 can be placed between the substrate 111 and the lens 110, with both ends respectively assembled and connected to the substrate 111 and the lens 110. This design ensures that the extension rod 113 is securely fixed between the two main components while providing sufficient flexibility to adjust the position of the LED bead 112. In this case, the extension rod 113 may require a more complex mechanical structure to ensure its effective operation on both sides while maintaining the compactness of the overall structure.

[0049] In this embodiment, the extension rod 113 is mounted on the substrate 111. This means that the main support point of the extension rod 113 is located on the substrate 111, and the telescopic function is achieved through the fixing point on the substrate 111. In this way, the LED beads 112 can change the distance between themselves and the light inlet 11a of the lens 110 by extending or shortening the extension rod 113, thereby achieving the purpose of precisely controlling the light 100a entering the lens 110. This setting simplifies the installation process of the extension rod 113 and also facilitates fine-tuning of the position of the LED beads 112. The installation position of the extension rod 113 can also be adjusted according to different models of the thick-walled component 100 of the vehicle lamp, as described in the above two embodiments, which will not be elaborated here.

[0050] Please refer to Figure 3 and Figure 6As shown, preferably, the extension rod 113 includes a telescopic rod 211 and a support rod 212. The main function of the extension rod is to provide necessary stability support for the entire telescopic structure, and one end of it is fixedly connected to the substrate 111 or the lens 110. This fixing method ensures that the extension rod 113 can be stably installed in the internal structure of the thick-walled component 100 of the vehicle lamp, while allowing its other end to extend and retract freely. Optionally, in this embodiment, the telescopic rod 211 can be designed as a single rod or multiple rods combined for use, depending on the required support strength and space constraints. Furthermore, the support rod 212 is located between the telescopic rods 211 and is specifically used to support the LED beads 112. One end of the support rod 212 is close to the lens 110, and the LED beads 112 are installed at this position. With this arrangement, when the extension rod 113 extends or retracts, the support rod 212 will drive the LED beads 112 to move along a predetermined path, thereby changing the relative distance between the LED beads 112 and the light inlet 11a of the lens 110.

[0051] Optionally, the support rod 212 may also have a certain adjustment mechanism, such as a fine-tuning screw or a sliding groove, so as to more precisely control the position of the LED bead 112 and make the LED bead 112 more aligned with the light inlet 11a.

[0052] Understandably, the entire extension rod 113 achieves dynamic adjustment of the position of the LED lamp bead 112 relative to the light inlet 11a of the lens 110 through the coordinated work of the telescopic rod 211 and the support rod 212. The telescopic rod 211 is responsible for providing structural stability and a fixed point, while the support rod 212 focuses on achieving precise positioning and movement of the LED lamp bead 112. This double-layer structure not only simplifies the overall design of the extension rod 113, but also improves the reliability and operability of the system.

[0053] Preferably, the telescopic rod 211 includes a first rod body 311 and a second rod body 312, which are connected to each other by nesting. The first rod body 311 is installed inside the second rod body 312, and one end of the second rod body 312 is fixed to the base plate 111, providing a stable support point. This double-layer structure design allows for a certain range of relative movement between the two rod bodies. The first rod body 311 can slide freely within the second rod body 312, thereby driving the LED beads 112 installed thereon to move. Furthermore, to ensure that the relative position between the first rod body 311 and the second rod body 312 can be accurately controlled, a limiting buckle 313 is provided on the first rod body 311. The limiting buckle 313 can move on the first rod body 311 and restrict or allow the movement of the first rod body 311 relative to the second rod body 312 by cooperating with a specific position inside the second rod body 312. When the position of the LED bead 112 needs to be fixed, it can be locked in a certain position by operating the limiting buckle 313, thereby fixing the first rod 311 in a specific position within the second rod 312. When the position of the LED bead 112 needs to be adjusted, the limiting buckle 313 can be released, allowing the first rod 311 to slide freely, thereby changing the distance between the LED bead 112 and the light inlet 11a of the lens 110. This design not only provides sufficient flexibility to meet the position adjustment under different lighting needs, but also ensures that the LED bead 112 remains stable in any selected position and will not be accidentally displaced due to external factors (such as vibration).

[0054] Specifically, in this embodiment, the limiting buckle 313 is designed as a slider, with openings on both the first rod 311 and the second rod 312. The limiting buckle 313 can move on the surface of the first rod 311. When the second rod 312 moves, the opening on the second rod 312 slides to a certain position on the first rod 311, and the opening on the second rod 312 aligns with the opening on the first rod 311. At this time, the limiting buckle 313 can be adjusted so that it can partially or completely engage with the opening where the first rod 311 and the second rod 312 overlap, locking the second rod 312 and the first rod 311 through friction and the buckling mechanism. When the limiting buckle 313 is not locked in the opening, the second rod 312 can slide freely within the first rod 311, and the user can easily adjust the length or position of the support rod 212. When it is necessary to fix the support rod 212 at a certain length, the user only needs to adjust the limiting buckle 313 to make the first rod 311 and the second rod 312 move relative to each other, and make the second rod 312 move to the required height, find the opening where the second rod 312 and the first rod 311 overlap, and adjust the limiting buckle 313 to re-engage it, so that it is engaged and locked.

[0055] like Figure 7 As shown, in some preferred embodiments, the telescopic rod 211 includes a sleeve rod 413, a compression rod 411 and a spring 412 installed inside the sleeve rod 413. The spring 412 is installed outside the compression rod 411, with one end connected to the compression rod 411 and the other end abutting against the bottom end of the support rod 212. When the LED bead 112 is installed on the ball joint 114 at the top of the compression rod 411, the LED bead 112 generates a force on the support rod 212, which increases the elastic force of the spring 412 on the support rod 212, exceeding the maximum elastic force that the support rod 212 can withstand on the spring 412. This allows the spring 412 to be triggered by external force and pop outward, driving the compression rod 411 to stretch outward from the sleeve rod 413, allowing the compression rod 411 to extend accordingly. The length of the compression rod 411 can be adjusted by rotation, thereby adjusting the overall length or position of the telescopic rod 211. By reasonably designing the stiffness of the spring 412 and the material and size of the compression rod 411, precise control of the movement range and support force of the support rod 212 can be achieved. Specifically, the support rod 212 includes a compression rod 411 made of elastic material and a spring 412. One end of the compression rod 411 is connected to the base plate 111 by welding or other fixing methods, while the other end is designed as a free end for contacting or connecting with the item to be loaded. A helical spring 412 is sleeved on a compression rod 411. One end of the spring is fixed to the substrate 111, and the other end is connected to the middle of the compression rod 411 or near the free end. When the LED bead 112 is installed, the connection of the spring 412 near the free end is unlocked by the installation of the LED bead 112, thereby decompressing the compression rod 411 from its original compressed state. This elastic force allows the compression rod 411 to maintain a certain rigidity while being able to extend a certain length, so that the LED bead 112 can move at the top of the compression rod 411, thereby approaching the light inlet 11a and corresponding to the light inlet 11a.

[0056] Please refer to Figure 4-7 As shown, preferably, the thick-walled component 100 of the headlight also includes a ball joint 114. The design of the ball joint 114 increases the flexibility of adjusting the position of the LED bulb 112. Specifically, the ball joint 114 is installed at the end of the telescopic rod near the light entrance 11a of the lens 110, while the LED bulb 112 is directly fixed to the ball joint 114. The design of the ball joint 114 allows it to rotate and tilt at multiple angles relative to the support rod 212, thereby forming a certain angle of motion. This structure allows the LED bulb 112 to still be finely adjusted through the ball joint 114 even after the position of the support rod 212 is fixed, ensuring that the light 100a can be accurately aligned with the light entrance 11a of the lens 110.

[0057] In a specific embodiment, the telescopic rod 211 is adjusted to an ideal position through the sleeve structure of the first rod body 311 and the second rod body 312, as well as the limiting buckle 313. At this point, if it is necessary to further optimize the relative angle between the LED bead 112 and the light inlet 11a of the lens 110, fine-tuning can be performed using the ball joint 114. The ball joint 114 typically consists of two hemispherical parts, one of which is fixed to the support rod 212, while the other can rotate freely around the center point. The LED bead 112 is mounted on this rotatable part, and by manually or with tools, the LED bead 112 can change its illumination direction within a certain range.

[0058] In this technical solution, the ball joint 114 is designed to allow the LED bead 112 to form a movable angle relative to the support rod 212, with the angle range limited to 0° to 60°. This design provides a wide adjustment range for the LED bead 112, allowing the operator to manually rotate the ball head to adjust it within the 0° to 60° range. Once the ideal angle is reached, the ball head is secured using a locking screw. This ensures that even when encountering bumps during vehicle movement, the LED bead 112 remains at the set angle without displacement. This design not only simplifies the multi-angle adjustment process of the LED bead 112 but also ensures precise optical control in various application scenarios.

[0059] In this technical solution, the lens 110 is designed to have multiple light inlets 11a, each corresponding to an LED 112. This multi-light-inlet design allows the headlight to produce more complex lighting patterns or provide a wider illumination coverage. Each LED 112 is supported by a ball joint 114 and its position and angle relative to its respective light inlet 11a can be adjusted as needed. In a specific embodiment, assuming the lens 110 has twenty-eight light inlets 11a, there will be twenty-eight corresponding LEDs 112, each connected by an independent ball joint 114. These ball joints 114 allow each LED 112 to adjust its illumination angle individually, ensuring that its light 100a accurately enters the corresponding light inlet 11a. When the position of a particular LED 112 needs to be adjusted, the ball head on the ball joint 114 can be manually rotated gently until the LED 112 is aligned with the light inlet 11a. Once adjusted, the position of the ball joint can be fixed using a locking mechanism (such as a screw or clip) on the ball joint 114. This ensures that each LED bead 112 remains at its set angle even during vehicle operation, preventing displacement due to external vibrations or other factors. Each LED bead 112 can either fit snugly against the edge of the light inlet 11a or be spaced at a certain distance as needed to accommodate different optical design requirements.

[0060] In summary, this invention provides a thick-walled component for automotive lamps. The key design feature is that the position of the LED beads can be adjusted to be closer to or further away from the lens. When the LED beads are adjusted to be closer to the lens, they can be more accurately aligned with the light entrance of the lens, thus concentrating the emitted light into the lens. After being processed by the internal structure of the lens, this light is emitted from the other side of the lens. This structure allows for planar design of the substrate, simplifying the design and production costs of the substrate. In addition, it improves the simplicity of the thick-walled component for automotive lamps. With this structural design, the entire automotive lamp system can flexibly adjust the position of the light source within different types of automotive lamp housings, thus adapting to different types of automotive lamps to achieve the required optical performance.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.

Claims

1. A thick-walled automotive lamp component, characterized by include: A lens with an entrance port for light; The substrate, at least on the side facing the lens, is designed to be planar; LED beads are located on the side of the substrate facing the lens, and the LED beads are electrically connected to the substrate; The LED beads are movable relative to the lens and can be aligned with the light inlet by the displacement, so that the light from the LED beads is concentrated into the light inlet and emitted outward from the other side of the lens; The thick-walled component of the vehicle lamp includes an extension rod, which is disposed between the light inlet of the lens and the substrate. The LED lamp bead is mounted on the extension rod and moves closer to or further away from the light inlet by extending and retracting the extension rod. The extension rod includes a telescopic rod and a support rod. The extension rod is used to connect the substrate and the lens, and the telescopic rod is used to install the LED beads. The telescopic rod includes a sleeve rod, a compression rod installed inside the sleeve rod, and a spring. The spring is installed outside the compression rod, with one end connected to the compression rod and the other end abutting against the bottom end of the support rod. It also includes a ball joint, which increases the flexibility of LED bead position adjustment. The ball joint is installed on the end of the telescopic rod near the lens light inlet, and the LED bead is directly fixed on the ball joint. When the LED beads are installed on the ball joint at the top of the compression rod, the LED beads will exert a force on the telescopic rod, which will increase the elastic force of the spring on the support rod. The spring can be triggered to pop outward under the action of external force, so that the LED beads can move at the top of the compression rod, thereby getting closer to the light inlet and corresponding to the light inlet.

2. The thick-walled automotive lamp component of claim 1, wherein: The extension rod is mounted on the base plate; Alternatively, the extension rod may be mounted on the lens; Alternatively, the extension rod may be located between the substrate and the lens and be assembled and connected to the substrate and the lens.

3. The thick walled automotive lamp component of claim 1, wherein: The light inlet is configured as a plurality of ports, the number of LED beads corresponds to the number of light inlets, and each LED bead is supported by a ball joint and abuts against the periphery of the light inlet or is spaced apart from the light inlet.
