[0025] Figure 1 Exemplarily shown is a schematic diagram of a light-emitting device according to the present utility model; Figure 2 Exemplarily shown is a schematic diagram of the light-emitting device according to the present utility model when a camera is installed in the accommodation middle.
[0026] As Figure 1 and 2 shown, the light-emitting device includes: a housing 101, and a first light-emitting component 102 and a second light-emitting component 103 that are symmetrically arranged left and right, and an accommodation space 104, which is configured to be arranged between the first light-emitting component 102 and the second light-emitting component 103 of the lamp component 101, and is configured to form a groove on the housing 101 of the lamp component 101. Designing the light-emitting components symmetrically can make the overall light-emitting device more beautiful.
[0027] Figure 3 Exemplarily shown is Figure 2 a schematic diagram of one of the light-emitting components of the light-emitting device according to the present utility model. The two light-emitting components have the same structure but are symmetric left and right to each other, so the other light-emitting component is not shown again. In one example, as Figure 3 shown, the first light-emitting component 102 and the second light-emitting component 103 both include a light source (not shown) and a light guide element 1015.
[0028] Among them, the light source can be any suitable light-emitting device, such as a halogen lamp, a xenon lamp, an LED, a laser, etc. According to actual needs, the light source can be arranged on a carrier. As an example, the light-emitting component may further include a circuit board, such as a PCB, and the light source is mounted on the circuit board.
[0029] The light guide element 1015 is made of a material suitable for transmitting light, such as, but not limited to, polymethyl methacrylate (PMMA), polycarbonate (PC), etc., thereby ensuring that light can propagate and exit in the light guide element.
[0030] In one example, as Figure 3 shown, the light guide element 1015 is an optical fiber rod with a circular cross-section. Such a design can save space to a greater extent.
[0031] In one example, the accommodation space 104 is arranged on the connection line of the two light guide elements 1015. Such a design can ensure a better appearance and smaller space requirements for the light-emitting device.
[0032] In one example, the light sources of the first light-emitting component 102 and the second light-emitting component 103 are both arranged at one end of the light guide element 1015 close to the accommodation space 104 to ensure the light-emitting effect of the light-emitting device.
[0033] For the case where the accommodation space 104 is left at the central position of the light-emitting device 100, in order to ensure the area of the light-emitting region, there is usually a small gap between the light-emitting regions of the first light-emitting component 102 and the second light-emitting component 103. This is likely to cause the light from the light source not to have a sufficient light mixing region, affecting the light-emitting effect, such as optical defects like bright spots, light leakage, and light spots.
[0034] In one example, as Figure 4 shown, the first light-emitting component 102 and the second light-emitting component 103 include a light-shielding structure 1016, which is arranged at one end of the light guide element 1015 close to the accommodation space 104 and is arranged circumferentially around the light guide element 1015. By providing the light-shielding structure 1016, light leakage caused by too short a light mixing region can be effectively avoided. Since the distance between the light-emitting regions of the first light-emitting component 102 and the second light-emitting component 103 is small in the transverse direction, the light guide elements of the first light-emitting component 102 and the second light-emitting component 103 can only have a very short light mixing distance, which will affect the uniform light emission of the light guide element and may cause problems such as light leakage and light spots. Adding the light-shielding structure 116 can effectively solve the foregoing problems.
[0035] In one example, a buckle 1018 is formed on the light-shielding structure 1016 to cooperate with the housing 101 of the light-emitting device 100, thereby providing fixation for the light-shielding structure 1016.
[0036] In one example, the first light-emitting component 102 and the second light-emitting component 103 further include a second light source at an end far from the accommodating space 104. The light guide element of the light-emitting component enables light to enter from both ends, which can increase the range of visible light, improve brightness and uniformity, and avoid visibility problems that may occur when viewing from the outer side angle. Moreover, by setting an RGB light source, a mixed light dynamic effect can also be generated.
[0037] In one example, the light-emitting device 100 further includes a cover. By providing the cover, the accommodating space 104 can be separated from the outside, so as to prevent the components placed in the accommodating space 104 from being affected by the external environment, ensure its normal operation, and extend its lifespan.
[0038] In one example, a camera is disposed in the accommodating space 104. By integrating the camera with the light-emitting device, vehicle body space can be saved to a certain extent while improving the appearance. In other examples, devices for detecting road conditions such as sensors can also be disposed in the accommodating space.
[0039] In one example, a vehicle logo is formed on the cover. For the case where a camera is not required, forming a vehicle logo on the cover can utilize the accommodating space, eliminating the need to separately design the light-emitting device for the high-end and low-end versions of the vehicle, thereby saving costs to a great extent and ensuring the beauty and consistency of the appearance.
[0040] In one example, the light-emitting device 100 according to the present application can be used as a high-mounted brake light of a vehicle. Of course, it can also be used to implement other lighting or signal indication functions such as turn signals, brake lights, side marker lights, parking lights, daytime running lights, position lights, grille lights, etc. The present application does not make specific limitations.
[0041] According to the design of the present utility model, the light-emitting device can integrate components such as a camera with the light-emitting device, which can save vehicle space and improve the appearance at the same time. The light-emitting device according to the present utility model can also ensure the uniformity and visibility of the light output effect, meeting relevant requirements.
[0042] In addition, the present utility model also provides a vehicle, which includes the aforementioned light-emitting device. The vehicle at least has the beneficial effects brought by the aforementioned light-emitting device 100. The term "vehicle" mentioned herein can refer to any type of vehicle, such as a motor vehicle, a motorcycle, or any other mobile machine capable of carrying at least one passenger or used for transporting people or goods.
[0043] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, but can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
