[0025] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0026] The following description, with reference to the accompanying drawings, describes a vehicle taillight according to an embodiment of this application.
[0027] like Figures 1-8 As shown, a vehicle taillight according to one embodiment of this application may include: a base shell 1, a reflector assembly 2, a decorative frame assembly 3, and a lamp cover 4.
[0028] The reflector assembly 2 and the decorative frame assembly 3 are respectively connected to the bottom shell 1, and the lampshade 4 is placed on the outside of the reflector assembly 2 and the decorative frame assembly 3, and the lampshade 4 is connected to the bottom shell 1.
[0029] The reflector assembly 2 includes a substrate, a first reflector 21, and a first position lamp PCB board 8.
[0030] It should be noted that the PCB (Printed Circuit Board) described in this embodiment is a circuit board composed of an insulating substrate, conductive lines and pads. It forms the circuit lines of electronic components on the substrate through printing and etching processes, which solves the technical problems of complex wiring and short lifespan of traditional wiring methods.
[0031] The base is located between the bottom shell 1 and the decorative frame assembly 3, and the first reflector 21 and the first position lamp PCB board 8 are respectively mounted on the base.
[0032] It should be noted that the substrate (not shown in the figure) described in this embodiment is an auxiliary component for mounting the first reflector 21 and the first position lamp PCB board 8. Its specific shape and structure can be determined according to the actual situation, and no specific limitation is made here.
[0033] The first position light PCB board 8 is equipped with an LED position light 23. The light source emitted by the LED position light 23 shines on the first reflector 21 and obtains reflected light.
[0034] It should be noted that the LED described in this embodiment is short for Light Emitting Diode, which is a commonly used light-emitting device that releases energy through the recombination of electrons and holes and is widely used in the lighting field.
[0035] The decorative frame assembly 3 includes a position light housing 5, wherein the position light housing 5 is a single-layer dual-color injection molded part, the single-layer dual-color injection molded part includes a diffusion material area 51 and a transparent material area 52, wherein reflected light shines on the diffusion material area 51, and multiple hemispherical structures are evenly distributed inside the transparent material area 52.
[0036] Specifically, the vehicle taillight mainly consists of a base shell 1, a reflector assembly 2, a decorative frame assembly 3, and a lamp cover 4. The reflector assembly 2 and the decorative frame assembly 3 are respectively mounted on the base shell 1, and the outer side is covered by the lamp cover 4 and sealed to the base shell 1.
[0037] The reflector assembly 2 includes a substrate, a first reflector 21, and a first position light PCB board 8. The substrate is located between the bottom shell 1 and the decorative frame assembly 3, and is used to support the first reflector 21 and the first position light PCB board 8. The first position light PCB board 8 integrates LED position lights 23, and the light emitted by them shines on the surface of the first reflector 21 and forms a guide beam after reflection.
[0038] The position light housing 5 in the decorative frame assembly 3 is made using a single-layer, dual-color injection molding process, and is divided into a diffusion material area 51 and a transparent material area 52. Reflected light first illuminates the diffusion material area 51, and after initial diffusion, enters the transparent material area 52. This area contains multiple uniformly distributed micro-hemispherical structures that can perform secondary refraction and homogenization of the incident light, allowing the light to be uniformly guided from the surface, achieving a soft and uniform visual illumination effect.
[0039] This structure, through the combination of a diffuser material region 51 and a transparent material region 52 with a hemispherical structure, effectively homogenizes light during transmission, thereby achieving uniform overall illumination. Relying solely on the minimum LED light source required to meet position light regulations, without the need for additional light sources or light guides, it simultaneously satisfies the regulatory requirements for signal functionality and dotted decorative visual effects, significantly enhancing the taillight's aesthetic appeal and better meeting consumers' aesthetic demands for automotive lighting.
[0040] To clearly illustrate the previous embodiment, in another embodiment of this application, the first position lamp PCB board 8 includes a single-sided position lamp PCB board and a double-sided position lamp PCB board.
[0041] The single-sided position light PCB board and the double-sided position light PCB board are respectively connected to the base through the first fixing component.
[0042] It should be noted that the first fastener described in this embodiment may include one or more of the following: a limiting structure, a screw, or a plastic fastener. The specific configuration of the limiting structure is prior art and is not specifically limited here.
[0043] In addition, LED position lights 23 are respectively installed on the single-sided position light PCB board and the double-sided position light PCB board described in this embodiment.
[0044] It should be noted that dual-side position lights are the normal and standard design, meaning that when the vehicle's position lights (parking lights) are normally turned on, both the left and right taillights will illuminate to indicate the vehicle's width and presence. Single-side position lights are usually a special function or mode, used in specific situations (such as temporary parking on the roadside at night) to illuminate only the front and rear position lights on the left or right side of the vehicle, in order to reduce power consumption and warn oncoming vehicles.
[0045] Specifically, when the driver turns on the rear position lights while driving the car, the first position light PCB board 8 receives the position light turn-on signal. When the first position light PCB board 8 (both side position light PCB boards and one side position light PCB board) receives the position light turn-on signal, the LED position light 23 will light up. The light emitted by the LED position light 23 shines on the aluminum-plated reflective surface 22 on the first reflector 21. The aluminum-plated reflective surface 22 on the first reflector 21 reflects the light onto the inner part of the position light 5. The light shining onto the inner part of the position light 5 will be evenly diffused by the diffusion material area 51 on the two-color injection molded part through the diffusion properties of the diffusion material itself. A portion of the diffused light will be evenly refracted out and transmitted through the lamp cover 4, thereby realizing the normal operation of the position light.
[0046] Another portion of the light will be evenly transmitted to the transparent material area 52, and the light will be refracted by the hemispherical structure with a diameter of 1mm inside the transparent material area 52 to form a uniform dotted decorative effect. Finally, the light with the dotted decorative effect will also shine on the lampshade 4 and be transmitted through the lampshade 4, thereby realizing the dotted decorative effect of the position light.
[0047] The operation of this position light does not require the addition of other components for light guiding, nor does it increase the number of light sources. It only uses the number of LEDs required for a normal position light. It not only achieves the light intensity required for the normal operation of the position light, but also serves as a decorative light with a dotted decorative effect for the car's taillights.
[0048] In one embodiment of this application, such as Figure 6 As shown, the junction of the diffusion material region 51 and the transparent material region 52 is provided with a first included angle 53 and a second included angle 54, wherein the first included angle 53 is 60° and the second included angle 54 is 120°.
[0049] It should be noted that, in this embodiment, the first included angle 53 at the junction of the diffusion material region 51 and the transparent material region 52 is 60°, and the second included angle 54 is 120°. This allows for a better refraction effect as light travels from the diffusion material region 51 into the transparent material region 52.
[0050] In addition, it also demonstrates an injection molding method that, compared with the traditional injection molding method (where the junction of the diffusion material region 51 and the transparent material region 52 is at a 90° angle), has the following advantages: ① Regarding mold processing: it is easier to process; ② Regarding the injection molding process: it can ensure full injection and avoid the problem of insufficient injection; ③ Regarding the injection molded part itself: the contact area of the intersecting part of the two-color materials is large, and they can support each other. The two are well bonded, which can effectively avoid the problem of joint breakage. ④ In terms of visual appeal: This injection molding method presents a gradual visual effect, further satisfying consumers' requirements for the appearance of car taillights.
[0051] In one embodiment of this application, the diameter of the hemispherical structure is 0.8-1.2 mm, and the distance between one hemispherical structure and another hemispherical structure is 2-4 mm.
[0052] Optionally, the diameter of the hemispherical structure is 1 mm, and the distance between one hemispherical structure and the other hemispherical structure is 3 mm.
[0053] Understandably, the hemispherical structure, with a diameter of approximately 1 mm and an optimized radius of curvature, can perform controlled secondary refraction of scattered light incident from the diffusion material region 51. This size ensures that each hemispherical unit can form a clear, full circular light spot, serving as the basic pixel unit for visual perception.
[0054] The 3mm spacing between adjacent light spots ensures that there is no obvious visual overlap causing a halo, nor are there excessively large dark areas that break the continuity of light. This distance matches the refraction angle of the hemispherical structure, allowing light to form a smooth optical gradient at the edges of adjacent light spots when it exits the surface of the transparent material area 52, thus splicing together a macroscopically uniform and continuous surface-emitting effect.
[0055] Each hemispherical structure acts as an independent microlens, directionally and gently refracting incident light off the surface. The optimized combination of size and spacing eliminates localized bright spots or shadows at the microscopic level, ensuring that the light output from the entire transparent material area 52 is visually highly uniform, meeting the light quality requirements of high-quality position lights. Therefore, the vehicle taillights only need to be equipped with a limited number of LED light sources that meet the minimum regulatory light distribution requirements. After being reflected by the first reflector 21 and initially scattered by the diffusion material area 51, the light source is refracted and enters the transparent material area 52. Then, through these densely and regularly arranged hemispherical structures, it undergoes final "shaping" and "extraction," simultaneously achieving two goals: first, meeting the regulatory requirements for the brightness and visibility of position lights; and second, forming a regular and aesthetically pleasing dot matrix decorative light effect, thereby satisfying consumer demand.
[0056] In one embodiment of this application, such as Figures 3-5 As shown, the first reflector 21 is provided with an aluminum-plated reflective surface 22.
[0057] Understandably, the aluminized reflective surface 22 possesses extremely high specular reflectivity (typically >90%), which minimizes the optical loss of light energy emitted by the LED position lights 23, LED brake lights 24, and LED turn signals 25. The smoothness and high consistency of the aluminized reflective surface 22 result in a more concentrated and regular initial shape of the reflected light spot. This provides a clear and controllable "light input" for subsequent scattering of light in the diffusion material region 51 and refraction in the semi-circular structure, avoiding the final output light from being hazy or uneven due to the initial scattered or uneven light spot.
[0058] In the embodiments of this application, when the LED position light 23 emits a light source, the mirror properties of the aluminum-plated reflective surface 22 can efficiently reflect the incident light at a precisely controllable angle to the diffusion material region 51 inside the position light. This ensures that every bit of light energy emitted by a limited number of LEDs is effectively collected and directed to the target area, physically reducing the number of light sources required to achieve the specified brightness, which is the basis for achieving a low-power, low-cost system design.
[0059] In one embodiment of this application, such as Figure 3 and Figure 4 As shown, the reflector assembly 2 also includes a brake light PCB board 11 and a turn signal PCB board 12.
[0060] The brake light PCB board 11 is equipped with an LED brake light 24, and the turn light PCB board 12 is equipped with an LED turn light 25. The brake light PCB board 11 and the turn light PCB board 12 are respectively mounted on the base by a second fastener.
[0061] It should be noted that the second fastener described in this embodiment may include one or more of the following: a limiting structure, a screw, or a plastic fastener. The specific configuration of the limiting structure is prior art and is not specifically limited here.
[0062] Specifically, when the driver presses the brake pedal, the brake light PCB board 11 receives a brake light activation signal. When the brake light PCB board 11 receives the brake light activation signal, the LED brake light 24 on the brake light PCB board 11 will light up. The light emitted by the LED brake light 24 directly shines on the aluminum-plated reflective surface 22 on the first reflector 21. The aluminum-plated reflective surface 22 on the first reflector 21 reflects the light onto the lamp cover 4 in the required shape, and then transmits it out through the lamp cover 4, thereby realizing the normal operation of the brake light.
[0063] When the driver turns on the turn signal while driving the car to a turn, the turn signal PCB board 12 receives the turn signal activation signal. When the turn signal PCB board 12 receives the turn signal activation signal, the LED turn signal 25 on the turn signal PCB board 12 will light up. The light emitted by the LED turn signal 25 shines on the aluminum-plated reflective surface 22 on the first reflector 21. The aluminum-plated reflective surface 22 on the first reflector 21 reflects the light onto the lamp cover 4 in the required shape and transmits it out through the lamp cover 4, thereby realizing the normal operation of the turn signal.
[0064] In one embodiment of this application, such as Figure 1 As shown, the decorative frame assembly 3 also includes a first decorative frame, wherein the position light housing 5 is connected to the first decorative frame via a third fastener.
[0065] It should be noted that the specific structure of the first decorative frame (not specifically marked in the figure) described in this embodiment can be determined according to the shape and structure of the actual vehicle taillight, and is not specifically limited here. The third fixing member may include one or more of the following: a limiting structure, screws, or plastic fixing clips. The specific configuration of the limiting structure is prior art and is not specifically limited here.
[0066] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the lampshade 4 and the base shell 1 are fixed together by hot plate welding.
[0067] Understandably, the hot plate welding process can form a uniform, dense, and continuous fusion sealing layer at the joint surface between the lamp cover 4 and the base shell 1, thereby constructing a highly reliable sealed inner cavity. This effectively prevents the intrusion of contaminants such as moisture and dust, ensuring the long-term operational stability and lifespan of internal precision optical components (such as reflectors, PCB boards, LEDs, etc.), and fully meeting the stringent waterproof and dustproof requirements of automotive lights.
[0068] In one embodiment of this application, such as Figure 6 As shown, the junction of the diffusion material region 51 and the transparent material region 52 is stepped, wherein the thickness of the diffusion material region 51 is greater than the thickness of the transparent material region 52, and the overlapping part of the diffusion material region 51 and the transparent material region 52 is greater than the remaining part of the diffusion material region 51.
[0069] Understandably, the stepped transition between the diffused material area 51 and the transparent material area 52 breaks the monotony of the flat surface. Through the staggered changes in material thickness and layers, a richer sense of three-dimensionality and depth is created visually, thereby enhancing the overall texture and design level of the taillights.
[0070] Furthermore, by making the thickness of the diffusion material region 51 greater than that of the transparent material region 52, the load-bearing foundation of the main structure is strengthened. The overlapping area of the two regions is larger than the rest of the diffusion material region 51, significantly increasing the bonding area between them. This design effectively improves the connection strength and durability by obtaining a larger connection interface, ensuring the structural stability of the component during long-term use.
[0071] A vehicle according to another embodiment of the present invention includes the vehicle taillights of the above embodiments and has all the beneficial effects of vehicle taillights, so they will not be described again here.
[0072] In summary, the vehicle taillight of this application embodiment, under the action of the first reflector, reflects the light source emitted by the LED position light into the position light housing. Without adding additional light sources or other light-emitting and light-guiding components, part of the light energy through the diffuser material area satisfies the indicator function requirements of the position light, while the other part of the light diffuses into the transparent material area, achieving a dotted decorative effect through light reflection and refraction, thereby further enhancing the appearance and texture of the car taillight and better meeting consumers' pursuit of visual aesthetics.
