[0020] Figures 1 to 3 A schematic diagram of a light-emitting component 100 according to an embodiment of this application is shown. Figure 1 As shown, a light-emitting component is provided, in Figure 1In this embodiment, the lens 20 of the light-emitting component 100 is omitted. The light-emitting component 100 includes: a light source 10, which is arranged on the circuit board 1 and configured to emit light; a lens 20, which is arranged in front of the circuit board 1 and the light source 10 and is used to emit light from the light source; a support member, which is arranged along the edge of the circuit board 1 and configured to provide support and fixation for the lens 20; wherein the support member includes a first support member 31 and a second support member 32 arranged opposite each other at the ends in the longitudinal direction of the circuit board 1.
[0021] In one specific example, the light source can be a light-emitting diode (LED) or a laser, or any suitable light source known or to be developed in the future; this application does not impose any specific limitations. The light source emits light within a half-space defined by its principal plane. The color of the emitted light is selected according to the required function. For this purpose, LEDs emitting white, red, or yellow light can be used to perform several illumination and / or signaling functions.
[0022] In one example, a plating or coating is formed on the support member. The plating is a metallic plating, and the coating is a metallic coating or a white coating. This is to reflect light and improve the uniformity of light output and light emission.
[0023] Due to the characteristics of the light source, the light emitted through the lens 20 has a lower brightness on the side closer to the second support 31 than in other areas, which fails to meet the uniformity requirements.
[0024] In one example, such as Figure 1 and 2 As shown, the light-emitting component 100 includes a reflector 40 and a second light source 11 at the end near the first support member 31. The reflector 40 is configured to reflect light from the second light source 11 toward the second support member 32. The reflection by the reflector 40 and the second support member 32 can improve the brightness on the side near the second support member 32 and improve the uniformity of the overall light emission effect.
[0025] The reflective surface of reflector 40 has an elliptical or parabolic profile. Specifically, the reflective surface is a surface obtained by rotating about an axis parallel to the optical axis. Alternatively, the reflective surface can also be a free-form surface, a swept surface, or an asymmetric surface. The term "parabolic" is generally used to describe reflectors whose surface has a single focal point (i.e., a converging region of light, that is, an area where light emitted by a light source placed in this converging region is projected a great distance after being reflected by the surface).
[0026] The second light source 11 is preferably positioned off-center from the reflective surface of the reflector 40 to avoid bright spots in the light output and improve uniformity.
[0027] In one example, such as Figure 3 As shown, the support also includes a third support 33 arranged along the length of the circuit board 1. The height of the second support 32 relative to the circuit board 1 is less than the height of the third support 33 relative to the circuit board 1. By extending the lens 20 toward the second support 32, an additional light-emitting surface is formed above the second support 32, so that light can be emitted when viewed from the side, thus meeting the requirements of relevant regulations.
[0028] In one example, optical microstructures are provided on the reflective surface of reflector 40 to diffuse the light reflected by reflector 40 and improve the uniformity of the light output. The optical microstructures can be formed in, but are not limited to, protrusions, depressions, serrations, textures, stripes, squares, etc. This application does not impose specific limitations on the location and form of the optical microstructures. By providing optical microstructures on reflector 40, light can also be reflected to the area above the second support 32, reaching the side of lens 20, thereby optimizing the visibility when viewed from the side at that location and meeting relevant regulatory requirements.
[0029] In one example, such as Figure 1 As shown, the second support member 32 may have optical microstructures to diffuse the emitted light and improve the uniformity of the light emission effect. The optical microstructures may be formed, but are not limited to, protrusions, depressions, serrations, textures, stripes, blocks, frosted surfaces, etc. This application does not impose specific limitations on the location and form of the optical microstructures.
[0030] According to a non-limiting embodiment of the present invention, the reflector 40 is integrally formed with the first support member 31. Integrating the reflector 40 and the first support member 31 simplifies the structure, facilitates manufacturing, reduces assembly steps, and lowers costs. In another example, the reflector 40 can also be a separate component, fixed to the first support member 31 or to the circuit board 1 in a suitable manner. For example, an opening is formed in the circuit board 1 for the locating pin of the reflector 40 to pass through, followed by fixation. The locating pin can be formed on an extension of the reflector 40.
[0031] According to a non-limiting embodiment of the present invention, such as Figure 1 As shown, the second light source 11 and the light source 10 are arranged on the same circuit board 1 to simplify the structure, facilitate production and processing, reduce assembly steps, and lower costs.
[0032] According to the light-emitting component of this utility model, by setting an additional reflector and light source, the uniformity of the light output effect can be effectively improved, and its structure is simple, which can achieve the ideal lighting effect at a low cost.
[0033] The light-emitting component 100 according to an embodiment of this application can be used as an example in any lighting and / or signaling device. This lighting and / or signaling device may include any type of vehicle lighting and / or signal lights, such as headlights, daytime running lights, center high-mounted brake lights, turn signals, position lights, taillights, etc. The light-emitting component 100 according to an embodiment of this application can also be used in areas other than vehicle lighting, such as streetlights, advertising lights, etc.
[0034] This application also provides a vehicle having the aforementioned light-emitting component 100, which has the advantages of the aforementioned light-emitting component. The term "vehicle" as used herein can refer to any type of vehicle, such as a car, motorcycle, or any other mobile machine capable of carrying at least one passenger or used for transporting people or goods.
[0035] Although this application has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of this application and should not be construed as a limitation thereof.
[0036] While some embodiments of the general concept of this application have been shown and described, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the general concept of this application, the scope of which is defined by the claims and their equivalents.
