[0050] The embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be understood that the embodiments of this application are primarily intended to illustrate possible implementations of the technical solutions of this application and should not be construed as limiting the technical solutions of this application. In this specification, identical or similar components are indicated by identical or similar reference numerals.

[0051] Figure 1 A schematic diagram of the optical guide component 100 provided in the embodiments of this application from a frontal view; Figure 2 for Figure 1 A schematic diagram of the optical guide component 100 as shown from the left side view; Figure 3 for Figure 1 The diagram shows the structure of the optical guide component 100 from a rear-view perspective.

[0052] like Figure 1-3As shown, an embodiment of this application provides a light guide assembly 100, which can be used in the headlights of motor vehicles. The light guide assembly includes a plurality of light guide blocks 10 and a connecting portion 30. The plurality of light guide blocks 10 are arranged sequentially along an arrangement direction X, spaced apart by gaps 20. Each light guide block 10 is a long, strip-shaped planar light guide extending approximately along a main light emission direction Z, and the plurality of light guide blocks 10 are arranged approximately parallel to each other. Each light guide block 10 includes a light-incident portion 11, a guiding portion 12, and a light-emitting portion 13 connected in sequence. The light-incident portion 11 receives light, the guiding portion 12 transmits the light received by the light-incident portion 11, and the light-emitting portion 13 emits the light L transmitted by the guiding portion 12. Each of the light guide blocks 10 includes a first surface 14 and a second surface 15 disposed opposite each other along the thickness direction Y, and a pair of side surfaces 16 disposed opposite each other along the arrangement direction X. The first surface 14 and the second surface 15 are respectively connected between the light input portion 11 and the light output portion 13. The side surfaces 16 are respectively connected between the light input portion 11 and the light output portion 13, and are also connected between the first surface 13 and the second surface 14. The gap 20 is located between the side surfaces 16 of adjacent light guide blocks 10. The arrangement direction X, the thickness direction Y, and the main light output direction Z are orthogonal to each other. The connecting portion 30 includes a first connecting bridge 31, which connects at least two of the plurality of light guide blocks 10. At least a portion of the first connecting bridge 31 is located on the first surface 14 of each connected light guide block 10. The first surface 14 is shown as the top surface in the figure. When the light guide assembly 100 is oriented at other angles in three-dimensional space, the first surface 14 may be presented as a left surface or a right surface. In other embodiments, at least a portion of the first connecting bridge 31 may be located on the second surface 15 of each of the connected light guide blocks 10, i.e., the bottom surface shown in the figure.

[0053] The first connecting bridge 31 can connect at least two separate light guide blocks 10 into a single unit, facilitating the integration of multiple optical functions through the light guide assembly 100. This not only reduces the overall size of the light guide assembly 100, but also saves space in vehicle lights when used therein, and simplifies installation. Furthermore, at least a portion of the first connecting bridge 31 is located on the first surface 14 of each connected light guide block 10, or at least a portion of the first connecting bridge 31 is located on the second surface 15 of each connected light guide block 10; that is, the first connecting bridge 31 is disposed on the same side of the connected light guide blocks 10. Compared to providing a connecting portion in the gap between multiple light guide blocks 10, the first connecting bridge 31 in this embodiment can significantly reduce light leakage between connected light guide blocks 10. Because the first connecting bridge 31 protrudes from the plurality of light guide blocks 10, that is, the first connecting bridge 31 and the plurality of light guide blocks 10 are offset from each other in the thickness direction Y and located on different planes, it is difficult for light rays propagating in the light guide blocks 10 along the main light emission direction Z to enter the first connecting bridge 31; even if a small amount of light leaks into the first connecting bridge 31, the leaked light will be greatly attenuated after reflection in the first connecting bridge 31, so that even less light rays can enter the adjacent light guide blocks 10; thereby reducing light crosstalk and light leakage between adjacent light guide blocks 10. This advantage is of great significance in multifunctional integrated vehicle lights.

[0054] In this embodiment, the first connecting bridge 31 is entirely located on the first surface 14 of each of the connected light guide blocks 10, which can further reduce light leakage between the light guide blocks 10. Of course, the first connecting bridge 31 can also be entirely located on the second surface 15 of each of the connected light guide blocks 10.

[0055] In this embodiment, the plurality of light guide blocks 10 and the connecting portion 30 can be formed from the same material, for example, the material forming the light guide assembly 100 can be the same PC material or PMMA material. The plurality of light guide blocks 10 and the connecting portion 30 can be a single piece formed by a one-time injection molding process. The entire light guide assembly 100 is a single piece formed from the same material by a one-time injection molding process, which can significantly speed up the production cycle of the light guide assembly 100 in mass production without increasing the cost. In addition, the positioning and installation of the light guide assembly 100 will be more convenient when it is subsequently assembled into the vehicle light.

[0056] In this embodiment, a total of 5 light guide blocks are shown. However, it is worth noting that in other embodiments, the number of light guide blocks 10 can be other values, such as 2, 3, 4, 6, or even more. This application does not specifically limit the specific number of the plurality of light guide blocks 10. Preferably, the first connecting bridge 31 can be connected to the first surface 14 of each of the plurality of light guide blocks 10, so that one first connecting bridge 31 can connect all the light guide blocks 10 into one piece, which simplifies the mold structure. Of course, the first connecting bridge 31 can also be set to connect to the second surface 15 of each of the plurality of light guide blocks 10, as long as normal demolding can be achieved during the manufacturing process.

[0057] The plurality of light guide blocks 10 includes a first light guide block 101 and a second light guide block 102, wherein the first light guide block 101 and the second light guide block 102 are arranged adjacent to each other. There can be a plurality of first light guide blocks 101 and a plurality of second light guide blocks 102, and the plurality of first light guide blocks 101 and the plurality of second light guide blocks 102 can be arranged alternately at intervals. Figure 1 The diagram shows three first light guide blocks 101 and two second light guide blocks 102, with the two second light guide blocks 102 respectively disposed between the three first light guide blocks 101. However, it is worth noting that in other embodiments, the number of first light guide blocks 101 and second light guide blocks 102 can be other values, and this application does not impose specific limitations on this. The first light guide blocks 101 and the second light guide blocks 102 can be used for different optical functions, thereby realizing the integration of multiple optical functions.

[0058] like Figure 1-3 As shown, the main light-emitting directions Z of the plurality of light guide blocks 10 are approximately the same, and each light guide block 10 extends approximately along the main light-emitting direction Z from the light-incident portion 11 to the light-emitting portion 13. The first surfaces 14 of the plurality of light guide blocks 10 all face the same side, and the second surfaces 15 of the plurality of light guide blocks 10 all face the same side. The light-incident portion 11 forms the rear portion of the light guide assembly 100, and the light-emitting portion 13 forms the front portion of the light guide assembly 100. Each light guide block 10's light-incident portion 11 includes a light-incident surface 111 and a first reflective surface 112. The light-incident surface 111 receives light L emitted from the light source, and the first reflective surface 112 reflects the light received from the light-incident surface 111 to the guide portion 12, resulting in better uniformity of the reflected light compared to the unreflected light.

[0059] Furthermore, each of the light guide blocks 10 has two second reflective surfaces 121 in its guiding portion 12. These two second reflective surfaces 121 are respectively disposed on the first surface 14 and the second surface 15. The two second reflective surfaces 121 are used to transmit the light received from the light-incident portion 11 to the light-emitting portion 13 after two reflections. The light-emitting portion 13 is a light-emitting surface with a diffusion structure. For example, an optical microstructure for diffusing light can be disposed on the light-emitting surface. The diffusion structure can further diffuse the light before it is emitted, resulting in better uniformity of the emitted light.

[0060] In this embodiment, the first connecting bridge 31 is closer to the light-incident section 11 than the light-emitting section 13. Of course, in other embodiments, the first connecting bridge 31 can also be positioned closer to the light-emitting section 13, or in the middle of the guide section 12, as long as it can stably connect the plurality of light guide blocks 10 together without affecting the overall light-emitting performance of the light guide assembly 100. The first connecting section 31 is typically designed to avoid the second reflective surface 121 to prevent affecting its function.

[0061] When the length of the light guide block 10 is relatively long, in order to ensure better stability of the entire light guide assembly 100, a second connecting bridge 32 can be provided in the light guide assembly 100. The second connecting bridge 32 is, for example, located closer to the light emitting part 13 than the light input part 11. Specifically, the second connecting bridge 32 can connect at least two light guide blocks 10, and the second connecting bridge 32 is located on the first surface 14 of each connected light guide block 10, or on the second surface 15 of each connected light guide block 10. Preferably, the second connecting bridge 32 is connected to the first surface 14 of all light guide blocks 10, or the second connecting bridge 32 is connected to the second surface 15 of all light guide blocks 10. In this case, the plurality of light guide blocks 10, the first connecting bridge 31, and the second connecting bridge 32 can be configured as a single piece formed from the same material through injection molding. The first connecting bridge 31 and the second connecting bridge 32 respectively connect the plurality of light guide blocks 10, which can significantly improve the stability of the light guide assembly 100, and both can reduce light leakage between the plurality of light guide blocks 10.

[0062] Furthermore, in order to manufacture a usable light guide assembly 100, the connecting portion 30 may further include a connecting structure 33 and a third connecting bridge 34. The connecting structure 33 is located on the side of the light input portion 11 away from the light output portion 13, that is, at the rear of the light guide assembly 100. The connecting structure 33 and the light input portion 11 are spaced apart, and the entire connecting structure 33 is an elongated strip extending approximately along the arrangement direction X. The third connecting bridge 34 connects at least one of the light guide blocks 10 to the connecting structure 33. Specifically, at least a portion of the third connecting bridge 34 is located on the first surface 14 of the connected light guide block 10 and a surface of the connecting structure 33 on the same side as the first surface 14, or at least a portion of the third connecting bridge 34 is located on the second surface 15 of the connected light guide block 10 and a surface of the connecting structure 33 on the same side as the second surface 15. For example, two pairs of third connecting bridges 34 are provided. Each pair of third connecting bridges 34 connects the wider second light guide block 102 to the connecting structure 33; however, no third connecting bridge 34 is required between the narrower first light guide block 101 and the connecting structure 33. This improves vibration resistance, and the connection structure 33 also prevents mode flow problems from affecting the optical performance of the light guide block 10. Of course, this application does not specifically limit the number or specific location of the third connecting bridges 34, as long as the connecting structure 33 and the plurality of light guide blocks 10 can be stably connected together.

[0063] The connecting portion 30 may further include a positioning structure 35, which is preferably disposed on the connecting structure 33. The positioning structure 35 can be used for limiting the position of the light guide assembly 100 between itself and other components. By providing the positioning structure 35 on the connecting structure 33, the need for additional positioning structures on the plurality of light guide blocks 10 can be reduced or completely eliminated, which is beneficial to the optical performance of the light guide assembly 100. In this case, the plurality of light guide blocks 10, the first connecting bridge 31, the second connecting bridge 32, the connecting structure 33, the third connecting bridge 34, and the positioning structure 35 are integral parts formed from the same material through a single injection molding process. It is worth noting that in the entire light guide assembly 100, only the plurality of light guide blocks 10 are used to guide light; other parts, such as the first connecting bridge 31, the second connecting bridge 32, the connecting structure 33, the third connecting bridge 34, and the positioning structure 35, are used for connecting or positioning the plurality of light guide blocks, not for guiding light. Therefore, these other parts, such as the connecting structure 33, are separated from the plurality of light guide blocks 10; or these other parts, such as the first connecting bridge 31, the second connecting bridge 32 and the third connecting bridge 34, are located at different heights from the plurality of light guide blocks 10, thereby avoiding light leakage between the plurality of light guide blocks 10.

[0064] Figure 4A schematic diagram of the structure of the vehicle headlight 1000 provided in an embodiment of this application from a frontal view; Figure 5 for Figure 4 The diagram shows the structure of the headlight 1000 from a rear view. Figure 6 for Figure 4 The exploded view of the headlight 1000 shown.

[0065] like Figure 4-6 As shown, embodiments of this application also provide a vehicle lamp 1000, which includes the light guide component 100 described in any of the above embodiments.

[0066] In this embodiment, in addition to the light guide assembly 100, the vehicle lamp 1000 also includes a light source assembly 200. The light source assembly 200 is mounted upside down on the light guide assembly 100 and is used to emit light. Specifically, the light source assembly 200 includes a circuit board and a light source soldered to the lower side of the circuit board. The light source may include multiple LEDs, such as RGB LEDs, dual-color LEDs, and / or single-color LEDs. Different light functions can use different light sources; for example, RGB LEDs can be used for exterior ambient lighting, yellow LEDs for turn signals, and white LEDs for position lights and daytime running lights. The circuit board is provided with limiting holes or limiting grooves 201. The positioning structure 35 on the light guide assembly 100 cooperates with the limiting holes or limiting grooves 201, so that the light source is positioned relative to the light-incident part 11, and the light emitted by the light source is coupled into the multiple light guide blocks 10 through the light-incident part 11. Some of the positioning structures 35 may have threaded holes, and external screws pass through the limiting holes or limiting grooves 201 and threaded holes of the circuit board in sequence to realize the installation and fixation between the circuit board and the light guide assembly 100 in the light source assembly 100.

[0067] The vehicle headlight 1000 may also include a support member 300 and a light shield 400 that cooperate with each other. Figure 7 It shows Figure 4 A schematic diagram of the structure of the support member 400 in the vehicle headlight 1000 shown; Figure 8 It shows Figure 4 The diagram shows the structure of the light-shielding member 400 in the vehicle headlight 1000. The support member 300 and the light-shielding member 400 cooperate to sandwich the plurality of light guide blocks 10 between them. The support member 300 mainly supports and shields the portion of the plurality of light guide blocks 10 near the light-incident portion 11. The light-shielding member 320 mainly supports and shields the portion of the plurality of light guide blocks 10 near the light-exit portion 13. The support member 300 and the light-shielding member 400 reliably fix the light guide assembly 100 in the motor vehicle and can block other parts of the plurality of light guide blocks 10 except for the light-incident portion 11 and the light-exit portion 13, preventing light leakage.

[0068] Specifically, the support member 300 includes a support portion 310 and a plurality of light-shielding arms 320 formed on the support portion 310. The support portion 310 supports the light guide assembly 100 and supports the portions of the plurality of light guide blocks 10 near the light-incident portion 11. The light-shielding arms 320 are inserted into the gaps 20 between the plurality of light guide blocks 10 to block light leakage between the plurality of light guide blocks 10. The light-shielding member 400 includes an arm portion 420 forming a mounting groove 410. The portions of the plurality of light guide blocks 10 near the light-emitting portion 13 are respectively positioned in different mounting grooves 410, and the arm portion 420 is used to block light leakage from the plurality of light guide blocks 10.

[0069] In some embodiments, the first light guide block 101 can be used for a first light function and a second light function, while the second light guide block 102 can only be used for the second light function. When the first light function is turned on, the second light function is turned off; when the first light function is turned off, the second light function can be turned on or off according to control commands. The first light function can be at least one of a position light, a turn signal, and a daytime running light; the second light function is an exterior ambient light, which can only be used when the vehicle is parked or stationary. Of course, in other embodiments, the vehicle light 1000 can also be used for other functions, which will not be listed here.

[0070] Embodiments of this application also provide a motor vehicle that includes the light guide assembly 100 or the headlight 1000 described in any of the above embodiments.

The dimensions and proportions in the drawings are merely illustrative and should not be construed as limiting this application.

[0072] While some embodiments of the general concept of this application have been shown and described, those skilled in the art will understand that this application may include many other equivalent embodiments without departing from the general inventive concept of this application, and the scope of protection of this application is defined by the claims.
