Therefore, they should not be construed as limitations on this invention.
[0022] Figures 1 to 5 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 100 is provided, comprising: a light source 10 disposed on a circuit board 1 and configured to emit light; a lens 20 disposed in front of the circuit board 1 and the light source 10 and used to emit light from the light source; and a support 30 disposed along the edge of the circuit board 1 and configured to provide support and fixation for the lens 20; wherein the light-emitting component 100 further comprises a reflector 40 configured to reflect light from the light source toward the support 30.
[0023] 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.
[0024] In one example, the support member 30 includes a first support member 31 and a second support member 32 disposed at the ends of the circuit board 1 in the width direction, wherein the height of the second support member 32 relative to the circuit board 1 is greater than the height of the first support member 31 relative to the circuit board 1.
[0025] In one example, a plating or coating is formed on the support member 30. 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.
[0026] 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 member 31 than in other areas, which fails to meet the uniformity requirements.
[0027] In one example, such as Figure 2As shown, the reflector 40 is disposed at one end near the first support member 31 and is configured to reflect light from the light source 10 toward the second support member 32. The light reflected by the reflector 40 toward the second support member 32 reaches the first support member 31 and is reflected again by the second support member 32 before exiting through the lens 20.
[0028] In one example, the light-emitting component 100 is provided with a second reflector 42 near the reflector 40. The second reflector 42 reflects the light from the light source 10 toward the end of the second support 32 near the lens 20, and the light reflected by the second support 32 exits directly through the lens 20. Figure 3 As shown.
[0029] 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).
[0030] In one example, the reflector 40 and the second reflector 42 are integrated. Integrating the reflector 40 and the second reflector 42 simplifies the structure, facilitates manufacturing, reduces assembly steps, and lowers costs. In another example, the reflector 40 and the second reflector 42 can also be separate components.
[0031] Reflector 40 and second reflector 42 can be integrally formed with the first support member 31, or can be fixed to the first support member 31 or to the circuit board 1 by appropriate means. For example, an opening can be formed in the circuit board 1 for the positioning pin of reflector 40 to pass through, and then fixed. The positioning pin can be formed on the extension of reflector 40. This application does not impose specific limitations.
[0032] In one example, optical microstructures may be provided on one or more of the reflector 40, the second reflector 42, and the support 30. These microstructures diffuse the light reflected by the reflector 40, improving the uniformity of the light output. The optical microstructures can be formed, but are not limited to, protrusions, depressions, serrations, textures, stripes, blocks, etc. This application does not impose specific limitations on the location and form of the optical microstructures.
[0033] In one example, such as Figure 4As shown, the support member 30 further includes a third support member 33 that is attached to the circuit board 1. An opening 34 is formed on the third support member 33 to expose the light source 10. The surface of the third support member 33 can reflect light to a certain extent, improving light efficiency. Exposing the light source 10 to the third support member 33 ensures that the light source 10 emits light smoothly. The size of the opening 34 is preferably slightly larger than the size of the light source 10.
[0034] In one example, the opening 34 of the third support 33 includes sidewalls 35 located on both sides of the light source 10, wherein the sidewalls 35 are configured to reflect light from the light source. The reflection of light from the light source 10 by the sidewalls on both sides of the opening 34 can improve luminous efficiency and enhance the uniformity of the light output.
[0035] In one example, such as Figure 4 and 5 As shown, the sidewalls 35 are inclined outward relative to the plane of the circuit board 1, meaning the two opposing sidewalls 35 are open upwards. This arrangement ensures the angle at which light is reflected. The sidewalls 35 are preferably arranged along the direction extending from the first support member 31 and the second support member 32 for better results.
[0036] The light-emitting component of this utility model can effectively improve the uniformity of light output, and its simple structure enables it to achieve ideal lighting effect at a low cost.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] 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.
