Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a light guide component, 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 automobiles, 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 outlined. To make the light strip more eye-catching, the individual LEDs can be sequentially lit and extinguished, creating a flowing light or breathing light effect. Market testing has shown that this flowing light or breathing light effect is quite popular with consumers.

[0004] However, during the manufacturing process, to achieve the flowing light or breathing light effect, multiple LED beads are needed in the light strip structure. Such a large number of LED beads undoubtedly increases the production cost of the vehicle lights, and the increased number of LED beads also places higher demands on the control system. Furthermore, if one or more of the LED beads fail, the flowing light or breathing light effect will be significantly diminished, and replacing the damaged LED beads is time-consuming and labor-intensive. Therefore, reducing the number of LED beads used in the lighting fixture while still achieving the flowing light or breathing light effect is the direction for simplifying the lighting fixture structure, reducing production costs, and subsequent 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 automobiles, 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 outlined. To make the light strip more eye-catching, the individual LEDs can be sequentially lit and extinguished, creating a flowing light or breathing light effect. Market testing has shown that this flowing light or breathing light effect is quite popular with consumers.

[0029] However, during the manufacturing process, to achieve the flowing light or breathing light effect, multiple LED beads are needed in the light strip structure. Such a large number of LED beads undoubtedly increases the production cost of the vehicle lights, and the increased number of LED beads also places higher demands on the control system. Furthermore, if one or more of the LED beads fail, the flowing light or breathing light effect will be significantly diminished, and replacing the damaged LED beads is time-consuming and labor-intensive. Therefore, reducing the number of LED beads used in the lighting fixture while still achieving the flowing light or breathing light effect is the direction for simplifying the lighting fixture structure, reducing production costs, and subsequent maintenance costs.

[0030] In response, this application proposes a light guide component. This light guide component scatters the light beam emitted by the LED beads through the light diffusing part, and then shines the scattered light beam outward through the reflective part to create a light strip effect. Moreover, by switching the individual LED beads on and off in sequence, the effect of flowing light or breathing light can be achieved. However, compared with the traditional light strip structure, the number of LED beads used is reduced, thereby reducing production costs and the difficulty of controlling LED beads.

[0031] In addition, this application also proposes a vehicle lamp and a car including the above-mentioned light guide components.

[0032] Reference Figure 1 The light guide assembly in the first aspect embodiment of this application includes an incident portion 100, a diffuser portion 200, and a reflector portion 300. The incident portion 100 is used to connect to an external LED chip. After a light beam is emitted from the LED chip, the beam is guided by the incident portion 100 and enters the light guide assembly. The diffuser portion 200 is used to diffuse the light beam guided by the incident portion 100. Inside the diffuser portion 200, the light beam is repeatedly reflected and refracted, thereby scattering multiple light beams from a single beam. The reflector portion 300 is used to reflect the light beams transmitted from the diffuser portion 200, so that each beam is emitted outward at a similar angle.

[0033] Specifically, the incident section 100 is used to guide the light beam emitted by the LED beads. The diffuser section 200 is connected to the incident section 100 to receive the guided light beam. It is worth noting that, referring to... Figure 2 and Figure 3 The incident portion 100 forms an acute angle with the length direction of the diffuser portion 200, so that the light beam in the incident portion 100 enters the diffuser portion 200 at an acute angle. The light beam can be repeatedly reflected within the diffuser portion 200 and spread along the length direction of the diffuser portion 200. Finally, the light beam can pass through the side of the diffuser portion 200 and enter the subsequent reflector portion 300.

[0034] The reflector 300 is connected to the diffuser 200 to receive the transmitted light beam. Specifically, the reflector 300 is mounted on the side of the diffuser 200, and the light beam passes through the side of the diffuser 200 and enters the reflector 300. Multiple reflecting prisms 310 are provided inside the reflector 300, and reflecting surfaces 311 are provided on the sides of the reflecting prisms 310 to reflect the light beam. Each light beam is dispersed outward in a manner perpendicular to the length direction of the reflector 300.

[0035] The incident part 100, the diffused part 200 and the reflective part 300 together form an integrated structure. This integrated structure is manufactured directly in the factory without the need for subsequent assembly, which reduces the difficulty of subsequent assembly and improves production efficiency.

[0036] Furthermore, there are multiple incident portions 100, which are equidistantly arranged along the length of the diffuser portion 200. Specifically, the number of incident portions 100 is the same as the number of external LED beads, and each LED bead is connected to an incident portion 100 in a one-to-one correspondence, so that the light beam emitted by each LED bead can enter the light guide assembly along its corresponding incident portion 100.

[0037] Furthermore, the incident part 100 is tubular, with one end of the incident part 100 used to connect to the LED lamp bead, and the other end of the incident part 100 connected to the diffuser part 200. When the LED lamp bead is turned on, the light beam can be continuously reflected in the incident part 100 until the direction of the light beam is approximately the same as the length direction of the incident part 100, thereby playing the role of guiding the light beam of the incident part 100.

[0038] Furthermore, there are multiple reflecting prisms 310, which are equidistantly arranged along the length of the reflecting section 300, and the reflecting surfaces 311 of each reflecting prism 310 are parallel to each other. Thus, by setting multiple reflecting prisms 310, the light beam can be reflected outward uniformly, and since the reflecting surfaces 311 of each reflecting prism 310 are parallel to each other, it can be ensured that the emitted light beams are in approximately the same direction, thereby guiding the light beam outward.

[0039] Furthermore, the light beam transmitted from the astigmatism section 200 enters through two adjacent reflecting prisms 310 and is reflected outward by the reflecting surface 311 of one of the reflecting prisms 310. Thus, only the light beam that enters precisely between two adjacent reflecting prisms 310 can be reflected to the outside, effectively filtering the light beam and ensuring that subsequent light beams reflected by the reflecting surface 311 have approximately the same direction. Light beams that cannot exit between two adjacent reflecting prisms 310 will continue to be reflected in the astigmatism section 200 or the reflecting section 300 until they can exit between any two adjacent reflecting prisms 310.

[0040] Furthermore, the integrated structure formed by the incident part 100, the scattering part 200, and the reflecting part 300 is a supporting structure, as shown in the reference. Figure 1 The plane of symmetry of the integrated structure is perpendicular to its length. Notably, the exit ports of each incident section 100 are all oriented towards the center of the integrated structure, causing the light beam to diffuse towards the center, resulting in higher brightness in the center compared to the ends. The purpose of this design is to bring the light beams emitted by each LED as close as possible to the center of the integrated structure, thereby attracting greater consumer attention.

[0041] Furthermore, this integrated structure is transparent, allowing the light beam to propagate freely within the incident section 100, the diffuser section 200, and the reflector section 300. In addition to the exit port of the reflector section 300, 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.

[0042] Furthermore, for the overall structure of the integrated structure, refer to Figure 4 The integrated structure includes an extension portion 410 and two bend portions 420. The two bend portions 420 are respectively disposed at both ends of the extension portion 410. The bend portions 420 are bent along the thickness direction of the extension portion 410, thereby forming an L-shaped structure at the end of the extension portion 410 to adapt to the outer contour of the car.

[0043] A vehicle lamp according to a second aspect embodiment of this application includes LED beads and the light guide assembly described above. The number of LED beads is the same as the number of incident parts 100, and each LED bead is connected to an incident part 100 in a one-to-one correspondence.

[0044] The automobile in the third aspect embodiment of this application includes an automobile body and the aforementioned headlights, the headlights being mounted on the automobile body.

[0045] 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.
