[0030] At present, the LED motorcycle tail lamp on the market mainly adopts the direct light emitting mode, that is, the LED lamp bead directly emits light to the rear. However, although this light emitting mode can provide sufficient brightness, due to the high brightness and small light emitting area of the LED lamp bead, the light is relatively concentrated, which is easy to cause the driver of the rear vehicle to have a dazzling feeling when driving at night, and there is a certain safety hazard.

[0031] In order to solve the technical problem, the utility model provides a kind of LED motorcycle tail lamp.

[0032] Please refer to Figures 1 to 4 In an embodiment of the utility model, the LED motorcycle tail lamp includes tail lamp holder 100, light guide piece 300 and light cup 400, tail lamp holder 100 is provided with light emitting assembly 200;Light guide piece 300 is arranged in tail lamp holder 100, light guide piece 300 is formed in the shape of an arc along the horizontal direction to the direction away from tail lamp holder 100, the top of light guide piece 300 is provided with the light guide groove 301 of notch upwards, the bottom wall of notch opposite light guide groove 301 is provided with the through hole 302 for light emitting assembly 200 to extend into, through hole 302 is close to tail lamp holder 100 and is arranged;The bottom of light cup 400 is provided with the light reflection groove 401 of opening downwards, light cup 400 is covered in light emitting assembly 200 at the position corresponding to through hole 302.

[0033] Specifically, the light-emitting assembly 200 is arranged in the tail lamp holder 100, the light guide piece 300 has an arc structure which is away from the tail lamp holder 100, the light guide groove 301 is arranged on the top of the light guide piece 300, the groove opening is upward, and the through hole 302 is arranged on the groove bottom wall and corresponds to the position of the light-emitting assembly 200. The emitted light rays of the light-emitting assembly 200 first enter the light reflection groove 401 at the bottom of the light cup 400. The light reflection groove 401 has a downward opening and corresponds to the position of the light-emitting assembly 200, the emitted light rays of the light-emitting assembly 200 are received and reflected by the light reflection groove 401, the propagation direction of the emitted light rays is changed, the concentration of the emitted light rays is weakened, and the first reflected light rays are formed. Then, the first reflected light rays are downwardly injected into the light guide groove 301 on the top of the light guide piece 300 through the light cup 400. The light guide piece 300 having the arc structure is beneficial to uniformly disperse the light rays to all directions, avoids the light rays being too concentrated, the first reflected light rays are further reflected and scattered in the light guide groove 301 to form the second reflected light rays and are emitted to the external environment. Since the second reflected light rays have been preliminarily processed by the light reflection groove 401 of the light cup 400 and further adjusted by the light guide groove 301 of the light guide piece 300, the brightness, concentration and glare degree of the second reflected light rays are effectively controlled, so that the uniform and soft lighting effect is realized, the risk of dazzling the driver of the rear vehicle is reduced, and the safety of night driving is improved.

[0034] In the technical scheme, the tail lamp holder 100, the light guide piece 300 and the light cup 400 are matched, the emitted light rays of the light-emitting assembly 200 are reflected by the light reflection groove 401 of the light cup 400, are further reflected and scattered by the light guide groove 301 of the light guide piece 300 and are emitted to the external environment, the propagation direction of the emitted light rays of the light-emitting assembly 200 and the light intensity distribution are changed. Since the emitted light rays of the light-emitting assembly 200 are reflected and scattered for multiple times, the brightness, concentration and glare degree are controlled, the uniform and soft lighting effect is finally realized, the safety of night driving is improved, the dazzling of the driver of the rear vehicle is reduced, and the safety hidden danger is reduced.

[0035] As an optional implementation, in an embodiment, the tail lamp holder 100 is a lamp body radiator, the front surface of the tail lamp holder 100 is provided with an open cavity for accommodating the PCBA, the light cup 400 and other components. The open cavity provides mounting space for the PCBA and the light cup 400, so that the components can be compactly integrated in the tail lamp holder 100, and the integration degree of the LED motorcycle tail lamp is improved.

[0036] In addition, the tail lamp holder 100 is also provided with an opening for mounting the power line and the connector plug. The opening provides a mounting channel for the power line and the connector plug, so that the electrical connection is simpler and more reliable.

[0037] Please continue to readFigure 1 and Figure 3 In the embodiment of the utility model, the top of the light guide piece 300 is concave downward to form a first groove 311 and a second groove 312, the groove depth of the first groove 311 is less than the groove depth of the second groove 312, the first groove 311 is arranged away from the tail lamp holder 100 along the horizontal direction, and the second groove 312 is arranged between the first groove 311 and the tail lamp holder 100, and the first groove 311 and the second groove 312 are transitionally connected to form a light guide groove 301.

[0038] Specifically, the first groove 311 and the second groove 312 are both concave structures formed at the top of the light guide piece 300. The groove depth of the first groove 311 is less than the groove depth of the second groove 312, that is, the concave depth of the first groove 311 is less than the concave depth of the second groove 312. The first groove 311 is arranged away from the tail lamp holder 100 along the horizontal direction, and the second groove 312 is arranged between the first groove 311 and the tail lamp holder 100. The first groove 311 is located at one end of the light guide piece 300 away from the tail lamp holder 100, the second groove 312 is located at one end of the light guide piece 300 close to the tail lamp holder 100, and the two are transitionally connected to form a complete light guide groove 301.

[0039] When the emitted light rays of the light emitting assembly 200 are reflected by the light reflection groove 401 of the light cup 400 to form first reflected light rays, the first reflected light rays first enter the second groove 312. Since the groove depth of the second groove 312 is large, it helps the first reflected light rays to be fully reflected and scattered inside, so that the light distribution is more uniform. Subsequently, the light rays enter the first groove 311 with a smaller groove depth, and the first groove 311 can further guide and adjust the first reflected light rays to make them more soft, so as to form second reflected light rays and emit them to the external environment.

[0040] The present embodiment utilizes the internal space of the light guide piece 300 by cooperation of the first groove 311 and the second groove 312, prolongs the propagation path of the light rays in the light guide piece 300, and improves the mixing degree and uniformity of the light rays. At the same time, since the groove depth of the first groove 311 is less than that of the second groove 312, the light rays emitted from the light guide piece 300 are more soft, the generation of glare is reduced, and the illumination quality is improved.

[0041] Please continue to refer to Figure 3 In the embodiment of the utility model, the side of the light guide piece 300 facing the tail lamp holder 100 is provided with a connecting port 303, and the second groove 312 communicates with the connecting port 303.

[0042] Specifically, one side of the light guide piece 300 is provided with a connecting port 303, which is used for structural connection with the tail lamp holder 100 or other components, so as to fix the position of the light guide piece 300 and ensure the guiding effect of the light. Not only the effective transmission and distribution of the light are ensured, but also the structural stability and reliability of the whole LED motorcycle tail lamp are enhanced.

[0043] In addition, the connecting port 303 makes the assembly and maintenance of the whole light guide piece 300 more convenient, and the light guide piece 300 can be quickly installed or replaced, thereby reducing the maintenance cost and time.

[0044] Please continue to refer to Figure 1 and Figure 3 In the embodiment of the utility model, the groove bottom wall of the second groove body 312 is provided with a plurality of through holes 302, and the plurality of through holes 302 are distributed in a V shape.

[0045] Specifically, the second groove body 312 is located at one end of the light guide piece 300 close to the tail lamp holder 100, and the groove depth is large, which is beneficial to the full reflection and scattering of the light in the inside. A plurality of through holes 302 are opened on the groove bottom wall of the second groove body 312, and the plurality of through holes 302 correspond to the positions of the light emitting assembly 200, which are used to introduce the light emitted by the light emitting assembly 200 into the inside of the second groove body 312.

[0046] It is worth noting that the plurality of through holes 302 are distributed in a V shape, that is, the arrangement shape of the through holes 302 is similar to the letter "V". The light can be better guided to form crossing and scattering in the inside of the second groove body 312, so that the light distribution is more uniform. At the same time, the V-shaped distribution of the through holes 302 also helps to weaken the direct intensity of the light and reduce the generation of glare.

[0047] When the light emitted by the light emitting assembly 200 enters the second groove body 312 through the V-shaped distributed through holes 302, the light will be reflected and scattered multiple times in the inside of the second groove body 312, and then is emitted from the first groove body 311 of the light guide piece 300. Since the light has been fully mixed and adjusted in the inside of the second groove body 312, the emitted light has moderate brightness and uniform distribution, and the glare is reduced.

[0048] Please continue to refer to Figure 1 and Figure 3 In the embodiment of the utility model, the light emitting assembly 200 includes a lamp plate 210 and a plurality of LED lamp beads 220, the plurality of LED lamp beads 220 are installed on the lamp plate 210, the lamp plate 210 is installed on the tail lamp rear shell, the light guide piece 300 is installed above the lamp plate 210, the number of the LED lamp beads 220 is consistent with the number of the through holes 302 and is set one by one, and each LED lamp bead 220 extends into the corresponding through hole 302.

[0049] Specifically, the light-emitting assembly 200 is composed of a lamp plate 210 and a plurality of LED lamp beads 220. The lamp plate 210 is used to provide mounting support and circuit connection for the LED lamp beads 220, ensuring stable operation of the LED lamp beads 220. The plurality of LED lamp beads 220 are actual light sources that obtain electrical energy through the lamp plate 210 and emit light. The lamp plate 210 is installed in the tail lamp rear shell, so that the light-emitting assembly 200 forms an integral whole with other components of the tail lamp.

[0050] Notably, the light guide 300 is installed above the lamp plate 210, and the number of through holes 302 opened on the light guide 300 is consistent with the number of LED lamp beads 220 and is arranged one-to-one. That is, each LED lamp bead 220 corresponds to a through hole 302, and the LED lamp bead 220 can extend into the corresponding through hole 302. When the LED lamp bead 220 emits light, the light can directly enter the inside of the light guide 300 through the corresponding through hole 302, avoiding light loss and scattering. At the same time, since each LED lamp bead 220 has an independent through hole 302, the light entering the light guide 300 can be more accurately controlled and adjusted, reducing mutual interference and achieving more uniform light distribution.

[0051] In addition, the extension of the LED lamp bead 220 into the through hole 302 can also serve to fix and protect the LED lamp bead 220, avoiding displacement or damage of the LED lamp bead 220 under vibration and impact, thereby improving the reliability and stability of the LED motorcycle tail lamp.

[0052] Please continue to refer to Figure 1 and Figure 4 In the embodiment of the present application, the light cup 400 is in a V-shaped structure that protrudes from the tail lamp rear shell in a horizontal direction away from the tail lamp rear shell.

[0053] It should be noted that the light reflection groove 401 is in a V-shaped structure that is adapted to the light cup 400.

[0054] Specifically, the light cup 400 presents a special V-shaped structure, with its starting point located at the tail lamp rear shell and then converging, i.e., tapering, in a horizontal direction away from the tail lamp rear shell. When the light emitted by the light-emitting assembly 200 strikes the V-shaped light cup 400, the light will be reflected and refracted in the light reflection groove 401 of the light cup 400. Due to the particularity of the V-shaped structure, the light will form intersections and scattering inside the light cup 400, thereby weakening the direct intensity of the light and reducing the generation of glare. At the same time, the V-shaped structure also helps to uniformly disperse the light in all directions, achieving a softer and more balanced lighting effect.

[0055] In the embodiment of the present application, the light-emitting assembly 200 is electrically connected to an external power supply through a tail lamp adapter plate 500, which is arranged in the tail lamp holder 100.

[0056] Specifically, in order to connect the power supply to the light-emitting assembly 200, the tail lamp adapter plate 500 serves as a connection between the external power supply and the light-emitting assembly 200, ensuring that the power supply can be safely and stably transmitted to the light-emitting assembly 200.

[0057] The tail lamp adapter plate 500 is arranged inside the tail lamp holder 100, which can protect the electrical connection from external environmental factors such as water and dust, and also helps to maintain the overall appearance and neatness of the tail lamp system. The built-in tail lamp adapter plate 500 reduces the need for external wiring and reduces the risk of failure caused by improper wiring or external damage.

[0058] In addition, the tail lamp adapter plate 500 is closely integrated with the tail lamp holder 100, which not only optimizes the use of space but also enhances the structural strength of the entire LED motorcycle tail lamp. Especially when encountering bumpy roads during motorcycle driving, the tail lamp adapter plate 500 can better withstand vibrations and impacts.

[0059] As an optional implementation, the tail lamp adapter plate 500 is electrically connected with the built-in turn signal, external turn signal, license plate light, daytime running light, and brake light on the tail lamp panel 210. One side of the tail lamp adapter plate 500 is connected with the tail lamp panel 210, and the other side is welded with a connector plug, so that the LED motorcycle tail lamp not only has comprehensive functions but also is convenient for quick connection and disconnection with the same plug (male and female plugs), thereby improving the compactness and maintenance convenience of the LED motorcycle tail lamp.

[0060] Specifically, the tail lamp adapter plate 500 is equipped with various electronic components responsible for controlling different light functions such as turn signals, brake warnings, etc. The tail lamp adapter plate 500 tightly integrates these functions on a small circuit board, making the entire LED motorcycle tail lamp more compact and reducing the number of external wiring and components, which not only optimizes the space utilization of the motorcycle but also enhances the overall aesthetics of the vehicle.

[0061] In addition, one side of the tail lamp adapter plate 500 is directly connected with the tail lamp panel 210, and the other side is welded with a connector plug. This allows the LED motorcycle tail lamp to be easily connected with an external power supply or other control systems through plug-in connection, providing higher flexibility and convenience. When maintenance or upgrading is needed, users or maintenance personnel can easily disconnect the connection, making the replacement or maintenance process of the LED motorcycle tail lamp simple and efficient.

[0062] In the embodiment of the utility model, the tail lamp holder 100 is provided with a heat dissipation fin 110 on the side away from the light guide 300.

[0063] Specifically, the heat dissipation fins 110 are arranged on the side of the tail lamp holder 100 away from the light guide 300. The heat dissipation fins 110 are separated from the light guide 300 to avoid affecting the optical performance of the light guide 300. At the same time, it is also beneficial for the heat dissipation fins 110 to directly contact with the external environment to accelerate the dissipation of heat.

[0064] The heat dissipation fins 110 increase the surface area of the tail lamp holder 100, improving the heat dissipation efficiency of the entire tail lamp system. When the LED lamp beads 220 are working, the heat generated will be transferred from the lamp panel 210 to the tail lamp holder 100 through heat conduction, and then quickly dissipated to the external environment through the heat dissipation fins 110. The heat dissipation fins 110 ensure that the LED lamp beads 220 can work within a better temperature range, thereby maintaining high light efficiency and long service life.

[0065] In the embodiment of the utility model, the tail lamp holder 100 is provided with a lampshade 600, and the lampshade 600 is sleeved on the light guide 300, the light emitting assembly 200 and the light cup 400.

[0066] In the embodiment of the utility model, the tail lamp holder 100 is provided with a lampshade 600, and the lampshade 600 is sleeved on the light guide 300, the light emitting assembly 200 and the light cup 400.

[0067] Specifically, the lampshade 600 is sleeved outside the light guide 300, the light emitting assembly 200 and the light cup 400 to form a protective layer, which can prevent water, dust and other substances from entering the inside of the tail lamp housing, thereby reducing the risk of damage or functional decline of the light guide 300, the light emitting assembly 200 and the light cup 400 caused by environmental factors.

[0068] In addition, the transparent or translucent material of the lampshade 600 not only protects the internal components, but also ensures the effective transmission of light, without hindering the dispersion of light and the lighting effect.

[0069] In the embodiment of the utility model, the surface of the lampshade 600 is provided with a local covering layer.

[0070] Specifically, the local covering layer can be set by various processes, such as oil spraying, silk screen printing, laser engraving, etc. Taking the oil spraying process as an example, by spraying opaque or translucent paint on specific areas of the surface of the lampshade 600, the light transmission of these areas can be effectively blocked or adjusted, thereby forming different light transmission effects from the uncoated areas. This method is simple to operate and has high flexibility, and various different shapes and patterns of light transmission parts can be customized according to user needs.

[0071] The local covering layer not only improves the aesthetics of the tail lamp, but also enhances the recognition of the tail lamp. It makes the motorcycle more easily recognized by other road users when driving at night, thereby improving the safety of driving.

[0072] The above merely illustrates the exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the technical concept of the present application and by using the content of the present application specification and drawings are included in the patent protection scope of the present application.
