[0027] The core of the utility model is to provide a light-emitting structure for a vehicle lamp, so as to reduce the occupied space of the light-emitting structure while realizing lighting of multiple light-emitting surfaces.

[0028] Another core of the utility model is to provide a vehicle lamp having the above-mentioned light-emitting structure for vehicle lamps.

[0029] Another core of the present invention is to provide a vehicle with the above-mentioned vehicle lamp.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The development of car lighting technology has been pursuing better lighting effects and more efficient energy utilization. With the advancement of technology, car lights have gradually evolved from the original halogen lamps to xenon lamps, LED lamps, and even laser lamps. These advances not only improve the intensity and service life of light, but also reduce energy consumption. In particular, the application of LED technology is widely praised for its high efficiency, long life and flexible design. In modern car light design, LED can not only provide sufficient brightness, but also realize the lighting effect of multiple light-emitting surfaces in various ways, thereby meeting the lighting effect and vehicle aesthetics, and increasing the user experience.

[0032] At present, if the automotive lighting industry needs to light up multiple light-emitting surfaces, the following two forms are mainly adopted. One is to achieve it by lighting up multiple thick walls or light guides, that is, by increasing the number of thick walls or light guides and the number of light sources at the same time, so as to achieve the effect of lighting up multiple light-emitting surfaces. However, this method increases the number of parts and light sources, so that the light-emitting structure will occupy a large amount of internal space and increase the production cost; the other is to light up a single thick wall or light guide and then light it up by covering it with a decorative frame, but the decorative frame needs to work closely with the thick wall or light guide, which increases the difficulty of assembly. At the same time, due to the setting of the decorative frame, the light-emitting structure will occupy a large amount of internal space and increase the production cost.

[0033] For this reason, Figure 1 As shown, the embodiment of the utility model discloses a light-emitting structure for a vehicle lamp, including a light guide structure 100. By arranging a light inlet 101 and at least two light outlets 102 on the light guide structure 100, it is possible to achieve the effect of two or more light-emitting surfaces in appearance with only one light source assembly 200, thereby reducing the occupied space of the light-emitting structure, and at the same time reducing the number of light source assemblies 200 and light guide structures 100 used, thereby reducing the production cost.

[0034] The following will be combined Figure 1 The light-emitting structure for a vehicle lamp disclosed in an embodiment of the utility model is specifically explained and illustrated.

[0035] like Figure 1 As shown, the light guide structure 100 is provided with a light inlet 101 and a light outlet 102, and there are at least two light outlets 102, and the light inlet 101 and the light outlet 102 are arranged on different planes, that is, the light inlet 101 and the light outlet 102 are not arranged on the same plane. Among them, the light inlet 101 can be arranged on one side of the light outlet 102, such as Figure 1 As shown, it can of course also be arranged between two adjacent light outlets 102. At the same time, the light source assembly 200 is arranged at the position of the light inlet 101 to inject light toward the light guide structure 100, and the light is emitted from each light outlet 102. When the light source assembly 200 is lit, the emitted light passes through the light inlet 101 of the light guide structure 100 and the light guide structure 100 and is respectively emitted from each light outlet 102, thereby forming the effect of multiple light-emitting surfaces in appearance. Through one light source assembly 200, the effect of two or more light-emitting surfaces can be achieved in appearance, which reduces the occupied space of the light-emitting structure, and at the same time can reduce the number of light source assemblies 200 and light guide structures 100 used, thereby reducing production costs.

[0036] like Figure 1As shown, there can be two light outlets 102, so as to form two light-emitting surfaces in appearance. Of course, the number of light outlets 102 can also be three, four or more to form the effect of multiple light-emitting surfaces. The specific number of light outlets 102 can be determined according to actual needs. In addition, when the light-emitting structure is used for a car lamp, the light-guiding structure 100 can adopt but is not limited to a thick-walled light-guiding strip, and can also adopt an optical fiber light-guiding strip, a nano-scale light-guiding strip or a multi-color light-guiding strip, etc., which is not limited herein.

[0037] In a specific embodiment, the light guide structure 100 includes a light guide surface 103 that can conduct light. For ease of understanding, the two ends of the light guide structure 100 are defined as a first end and a second end, respectively, and the light inlet 101 is located at the first end of the light guide structure 100, and the light outlet 102 is located at the second end of the light guide structure 100. Among them, the light outlet 102 can adopt but is not limited to a strip structure, and can also adopt a ring structure or a combined structure to form a light-emitting surface of various forms to improve the lighting effect of the car lamp. When the light outlet 102 is a strip structure, each light outlet 102 is arranged parallel to the light guide surface 103, that is, each light outlet 102 is stacked and arranged at the second end of the light guide structure 100, and the light inlet 101 is arranged at the first end of the light guide structure 100. If there are two light outlets 102 and the light inlet 101 is located between the two light outlets 102, after the light source assembly 200 is lit, the emitted light passes through the light inlet 101 at the first end of the light guide structure 100, is transmitted along the light guide structure 100, and is respectively emitted from each light outlet 102, thereby forming the effect of two light-emitting surfaces in appearance.

[0038] Furthermore, in order to increase the visual sense of hierarchy, each light outlet 102 is staggered along the direction of the light guide surface 103, so that the headlights can create more light and shadow levels. When the vehicle is driving at night, it can have a better visual sense of hierarchy, which improves the appearance and recognition of the vehicle. At the same time, it makes the vehicle more eye-catching when driving at night, and increases other drivers' recognition of the vehicle, thereby reducing the risk of traffic accidents. Specifically, when there are two light outlets 102, the two light outlets 102 are arranged one after the other along the light conduction direction of the light guide structure 100, so that the light can be distributed more reasonably to meet the lighting needs of different positions. At the same time, it can effectively reduce the heat concentration in a single area and improve the overall service life of the headlights.

[0039] It should be noted that when there are three or more light outlets 102, each light outlet 102 can be stacked and arranged, and each light outlet 102 can be arranged alternately one after another along the light transmission direction of the light guide structure 100. Of course, each light outlet 102 can also be arranged in a gradient along the light transmission direction of the light guide structure 100 to increase the visual layering. Alternatively, each light outlet 102 is distributed in a ring shape, and each light outlet 102 can be arranged alternately one after another or arranged in a gradient along the light transmission direction of the light guide structure 100, so as to achieve a cooler lighting effect.

[0040] Furthermore, if Figure 1 As shown, in a specific embodiment, the light inlet 101 is arranged on one side of the light outlet 102, and the light guide structure 100 further includes a reflective surface 104, and the light is reflected by the reflective surface 104 to each light outlet 102. Specifically, the light guide structure 100 is an L-shaped structure, that is, the first end and the second end of the light guide structure 100 are arranged perpendicular to each other. When the light inlet 101 is located at the first end of the light guide structure 100, and the light outlet 102 is located at the second end of the light guide structure 100, the light inlet 101 is located on one side of the light outlet 102. At this time, when the light source assembly 200 of the light inlet 101 is lit, the emitted light passes through the light inlet 101 at the first end of the light guide structure 100 along the horizontal light guide surface ( Figure 1 The light is transmitted to the reflective surface 104 and then reflected, and then transmitted along the vertical guide surface ( Figure 1 The light is transmitted by the light outlets 102 at the second end of the light guide structure 100, thereby forming a plurality of light-emitting surfaces in appearance. By providing the reflective surface 104, the light incident from the light source assembly 200 is reflected to the positions of the light outlets 102, so that the space in the vehicle lamp can be reasonably utilized, and the space occupied by the light-emitting structure when installed can be reduced.

[0041] Furthermore, if Figure 1As shown, the reflective surface 104 is tilted, and there is a preset angle between the reflective surface 104 and the light guide surface 103 of the light guide structure 100. Specifically, the reflective surface 104 is arranged at the corner position of the light guide structure 100, and the preset angle between the reflective surface 104 and the light guide surface 103 of the light guide structure 100 can be but not limited to 45°. When the light incident from the light source assembly 200 is incident along the horizontal light guide surface parallel to the light guide structure 100, the preset angle between the reflective surface 104 and the light guide surface 103 of the light guide structure 100 can be 45°. When the light incident from the light source assembly 200 is incident at a certain angle to the horizontal light guide surface of the light guide structure 100, the preset angle between the reflective surface 104 and the light guide surface 103 of the light guide structure 100 needs to be adjusted according to the angle between the light incident from the light source assembly 200 and the horizontal light guide surface of the light guide structure 100, so as to ensure that the light incident from the light source assembly 200 can be reflected to the position of each light outlet 102 through the reflective surface 104. At the same time, the reflective surface 104 and the light guide structure 100 can adopt, but not limited to, an integrated structure. In this embodiment, the reflective surface 104 is formed by cutting the light guide structure 100 so as to reduce the size of the light guide structure 100 while reflecting the light incident from the light source assembly 200 to the positions of the light outlets 102 , thereby reducing the space occupied by the light emitting structure.

[0042] It should be noted that the horizontal light guide surface and the vertical guide surface in the above embodiment are both Figure 1 In actual use, it is necessary to Figure 1 The light guide structure 100 is shown rotated 90° counterclockwise or clockwise.

[0043] Further, the light source assembly 200 includes a circuit board 201 and a light source 202 disposed on the circuit board 201. In this embodiment, the light source 202 may be, but not limited to, an LED, a laser light source, a xenon light source, or a halogen light source. When LED lamp beads are used, multiple color displays can be achieved by adjusting the current and optical design, which is beneficial to improving visibility and ensuring road safety. In addition, LED light sources with different color temperatures and color effects can provide better road recognition and visual comfort, while having lower energy consumption. In addition, LED supports more nuanced adaptive headlight control, such as matrix technology, which can turn off a single LED to avoid blinding oncoming vehicles, thereby providing the best lighting effect while enhancing the safety of night driving. In order to prevent light from irradiating the external environment and causing heat concentration at other parts, an anti-transmission layer is coated on the outer side of the light guide structure 100 to prevent light from passing through the light guide structure 100 or refracting through the light surface 104 to the external environment, causing heat concentration at other parts. Among them, the anti-transmission layer may be, but not limited to, graphite material.
