Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a light transmission structure, an automotive lamp, and an automobile. Background Technology

[0002] Currently, in order to improve the aesthetics of family cars and win more consumer favor in the market, the headlight system, as the most conspicuous part of a car, is a top priority for improvement. Traditional headlights mainly include low beams, high beams, turn signals, and brake lights, which have practical functions. However, in recent years, in order to make their cars more differentiated from those of competitors, more and more car manufacturers have added headlights that only have decorative functions.

[0003] These decorative headlights are typically installed on the exterior of the car, with light strip structures being the most common. When illuminated, these light strips create a band of light on the car's surface, through which patterns or lines can be drawn. Market testing has shown that this type of light strip structure is quite popular with consumers.

[0004] However, during the manufacturing process, multiple LED chips are required in the light strip structure. This increased number of LED chips undoubtedly raises the production cost of the vehicle lights, and it also places higher demands on the control system. Furthermore, if one or more LED chips fail, the lighting effect of the light strip structure will be significantly reduced, and replacing the damaged LED chips is time-consuming and labor-intensive. Therefore, reducing the number of LED chips used in the lighting fixture while still achieving the desired light strip effect is the way to simplify the fixture structure and reduce production and maintenance costs.

[0027] Currently, in order to improve the aesthetics of family cars and win more consumer favor in the market, the headlight system, as the most conspicuous part of a car, is a top priority for improvement. Traditional headlights mainly include low beams, high beams, turn signals, and brake lights, which have practical functions. However, in recent years, in order to make their cars more differentiated from those of competitors, more and more car manufacturers have added headlights that only have decorative functions.

[0028] These decorative headlights are typically installed on the exterior of the car, with light strip structures being the most common. When illuminated, these light strips create a band of light on the car's surface, through which patterns or lines can be drawn. Market testing has shown that this type of light strip structure is quite popular with consumers.

[0029] However, during the manufacturing process, multiple LED chips are required in the light strip structure. This increased number of LED chips undoubtedly raises the production cost of the vehicle lights, and it also places higher demands on the control system. Furthermore, if one or more LED chips fail, the lighting effect of the light strip structure will be significantly reduced, and replacing the damaged LED chips is time-consuming and labor-intensive. Therefore, reducing the number of LED chips used in the lighting fixture while still achieving the desired light strip effect is the way to simplify the fixture structure and reduce production and maintenance costs.

[0030] In response, this application proposes a light transmission structure in which the light beam emitted by the LED bulb enters from the end of the incident section, is transported along the incident section, and passes through to the exit section on one side, where the beam is reflected outward by reflective teeth. This structure requires only a small number of LED bulbs, but can still produce a light strip-like effect, thereby reducing the production cost of automotive lights by reducing the number of LED bulbs.

[0031] In addition, this application also proposes a vehicle lamp and automobile, which includes the above-mentioned light transmission structure.

[0032] Reference Figure 1The light transmission structure in the first aspect embodiment of this application includes an emitting section 100, reflective teeth (not shown), and an incident section 200. The incident section 200 guides the light beam emitted by external LED chips into the light transmission structure, preparing for subsequent reflection and emission. The reflective teeth reflect the light beams guided by the incident section 200, ensuring that each beam enters the emitting section 100 at a similar angle, preparing for subsequent emission. Each beam undergoes multiple reflections within the emitting section 100 to bring its emission direction closer together, creating a near-parallel emission effect and maximizing the utilization of the light beams emitted by the LED chips, ensuring the final light brightness meets requirements.

[0033] Specifically, the ejector section 100 has a strip-shaped structure, and the first side surface of the ejector section 100 is along the first direction (refer to...). Figure 1 The beam transitions from the x-direction of the beam to the second side, where an emission port 110 is provided. The emission port 110 extends along the length of the emission portion 100. Thus, when the beam is emitted outward from the strip-shaped emission port 110, the entire emission port 110 presents a light strip visual effect, meeting the market demand for strip-shaped vehicle lights.

[0034] Multiple reflective teeth are arranged within the emission section 100, specifically near the first side of the emission section 100. The sides of the reflective teeth have reflective surfaces. When a light beam enters the emission section 100, the beam is illuminated by the reflective surfaces of the reflective teeth and directed towards the emission port 110 of the emission section 100, ultimately emitting outward from the emission port 110. It is easily understood that the arrangement of the reflective teeth depends on the position and angle at which the light beam enters the emission section 100, and their function is to reflect the light beam to the emission port 110.

[0035] The incident portion 200 has a strip-shaped structure, and its side surface is attached to the exit portion 100, making the light transmission structure more uniform in appearance. It is worth noting that the light beam can penetrate from the incident portion 200 to the exit portion 100, specifically from the side surface of the incident portion 200. The end of the incident portion 200 is used to connect to an LED bead, and the end of the incident portion 200 is curved and forms an acute angle with the first direction. Thus, on the one hand, the light beam enters from the end of the incident part 200 and can propagate along the length of the incident part 200, so that the entire incident part 200 is lit up. When the light beam propagates into the exit part 100, it is more uniform and easier to achieve the light strip effect. On the other hand, since the end of the incident part 200 forms an acute angle with the first direction, the light beam has an initial velocity in the first direction. After repeated reflection in the incident part 200, it is easier to enter the exit part 100 along the side of the incident part 200, thereby completing the penetration of the light beam and causing the light beam to enter the exit part 100.

[0036] Both the emission section 100 and the incident section 200 are transparent, allowing the light beam to be conducted within them and tending to be reflected when it comes into contact with the boundary. The light beam generated by the LED lamp bead can be injected from the end of the incident section 200, and the reflective teeth can reflect the light beam to the emission port 110 through the reflective surface.

[0037] Furthermore, referring to Figure 2 The emitting portion 100 is arc-shaped, allowing it to better fit the outer contour of the vehicle and create a more rounded curve. Correspondingly, the incident portion 200 also adopts an arc-shaped structure to fit the emitting portion, improving the overall shape consistency of the light transmission structure. It is easy to understand that the curvature of the arc-shaped structure of the emitting portion 100 or the incident portion 200 can be selected based on the actual outer contour curvature of the vehicle, thereby ensuring that the light transmission structure fits the outer contour of the vehicle.

[0038] Furthermore, both the emitting section 100 and the incident section 200 are symmetrical structures with the same plane of symmetry, perpendicular to the length directions of both the emitting section 100 and the incident section 200. LED beads are mounted at both ends of the incident section 200, and the two LED beads project a light beam towards the center of the incident section 200. Thus, the light beams projected by the two LED beads converge in the incident section 200, are reflected, and then enter the emitting section 100, finally emitting outwards from the outlet of the emitting section 100. This design uses only two LED beads to achieve an effect similar to a light strip structure, significantly reducing the number of LED beads used compared to traditional light strip structures, thereby lowering the production cost of the vehicle light structure.

[0039] Furthermore, multiple focusing lenses 111 are installed at the emission port 110. Each focusing lens 111 is a concave-convex mirror with a curved surface, designed to converge the emitted light beam, creating the visual effect of multiple light points to satisfy the aesthetic preferences of some consumers. Each focusing lens 111 can be mounted on a transparent base plate and then mounted at the emission port 110 using this base plate; alternatively, a grid can be installed at the emission port 110, with each focusing lens 111 fixed within its open mesh. The installation methods for each focusing lens 111 will not be elaborated further here.

[0040] Specifically, the reflective teeth are arranged at equal intervals along the length of the emission section 100, thereby uniformly reflecting the light beam transmitted from the incident section 200. The number of reflective teeth can be adjusted according to the actual situation to avoid affecting the passage of the light beam due to too many teeth, or to avoid the distance between two adjacent reflective teeth being too large due to too few teeth, resulting in uneven brightness of the light strip and affecting the final presentation effect.

[0041] Optionally, in some embodiments, the light transmission structure further includes a reflective portion 300, which is a transparent element, and the first surface of the reflective portion 300 is along the second direction (refer to...). Figure 1 The light beam transitions from the y-direction of the reflector 300 to the second surface. The first surface of the reflector 300 is connected to the incident part 200, and the second surface of the reflector 300 is connected to the exiting part 100. Thus, after the light beam enters the light transmission structure through the exiting part 100, it first moves along the second direction of the reflector 300, then moves along the first direction after entering the exiting part 100, and finally exits outward from the exit port 110 of the exiting part 100.

[0042] Correspondingly, the end of the incident portion 200 forms an acute angle with the second direction. The purpose of this design is to give the light beam incident at the end of the incident portion 200 an initial velocity in the second direction. After repeated reflections in the incident portion 200, the light beam is more likely to enter the reflecting portion 300 along the side of the incident portion 200, thereby completing the penetration of the light beam and causing the light beam to enter the reflecting portion 300.

[0043] Furthermore, the emitting part 100, the incident part 200, and the reflecting part 300 together constitute an integrated structure. This integrated structure is a transparent component, which can be manufactured as a single unit in a factory, eliminating the need for subsequent assembly, reducing assembly difficulty, and improving assembly efficiency. In addition to the incident port and the exit port 110 of the emitting part 100, a light-shielding layer can be applied to the outer surface of the integrated structure to prevent the light beam from escaping from other locations. This light-shielding layer can be applied as a coating to the integrated structure, or a housing can be installed on the outer surface of the integrated structure to achieve the light-shielding effect.

[0044] A vehicle lamp according to a second aspect embodiment of this application includes an LED lamp bead and the light transmission structure described above. The LED lamp bead is installed at the end of the incident part 200 and is used to emit light and project a light beam from the end of the incident part 200 into the interior of the incident part 200.

[0045] An automobile according to a third aspect embodiment of this application includes an automobile body and the aforementioned headlights, the headlights being mounted on the automobile body.

[0046] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
