[0026] The reflector and the rear fog lamp having the same according to the embodiment of the utility model will be described in detail below with reference to the accompanying drawings.
[0027] like Figure 1-Figure 3 As shown, the reflector and the rear fog lamp having the same according to the embodiment of the utility model include: a main body 1, the main body 1 is a parabola with a focus, a reflective surface is formed on one side of the main body 1, an aluminum layer is formed on the reflective surface, the main body 1 is composed of a plurality of reflective units 2, and the plurality of reflective units 2 can form a plurality of diamond-shaped light spots after reflecting the light.
[0028] In the present embodiment, a parabola with a focus is used to realize the formation of light into parallel light for emission, so that the light is reflected to the light emitting direction, and the light is prevented from deviating from the light emitting direction, so as to reduce light loss and improve the utilization rate of light. An aluminum layer is used to increase the reflectivity of light. Therefore, an aluminum layer is provided on the parabola with a focus to improve the lighting effect. The main body 1 has a simple structure, which reduces the thickness requirement while meeting the lighting effect, thereby reducing the volume and saving the occupied space. In addition, by providing the reflective unit 2, a diamond-shaped light spot is achieved, which meets the functional regulations of the rear fog lamp and further improves the lighting effect.
[0029] The thickness of the aluminum layer can be 30 μm-200 μm to ensure the required system light efficiency.
[0030] The reflective unit 2 is a parabola with a focus, and the focuses of the plurality of reflective units 2 are concentric with the focus of the main body 1 .
[0031] In this embodiment, a plurality of reflective units 2 and the main body 1 share a focus, thereby achieving a unified reflection direction, so that the light is emitted in the light-emitting direction, thereby satisfying the diamond-shaped light spot and ensuring the utilization rate of the light.
[0032] The projection surface of the reflective unit 2 is triangular, and the projection surfaces of two adjacent reflective units 2 form a rhombus. The two triangular light spots form a rhombus light spot, which enhances the light at the overlap of the two triangles and improves the central light intensity.
[0033] The thickness of the main body 1 is 2-3 mm; the main body 1 and the reflective unit 2 are integrally formed, which reduces the manufacturing process of the main body 1 and avoids the installation of the reflective unit 2. Therefore, while ensuring the accuracy of the angle of the reflective unit 2, it reduces the installation difficulty and the space required for installation, further reducing the space occupied by the main body 1.
[0034] The main body 1 is a plastic layer, and the main body 1 can be made of PMMA material or PC material according to needs, and can be transparent, white, black, etc. The plastic layer can be used to prepare the main body 1 and the reflective unit 2 using an injection molding process, thereby reducing the weight of the reflector and reducing the production cost.
[0035] A rear fog lamp adopts the above-mentioned reflector, including a light source and a lampshade, wherein the light source is located at the focus of a main body 1, the reflective surface is located in the light-emitting direction of the light source, the lampshade is located in the reflective direction of the main body 1, and a diffusion pattern is formed on the lampshade; the focus of the main body 1 is higher than the main body 1 to prevent the light source from blocking the light reflected by the main body 1.
[0036] In this embodiment, the light source emits light onto the main body 1, which is reflected by the main body 1 to the light emitting direction, so that the light is emitted through the lampshade. During the emission process, the light is diffused by the diffusion pattern, thereby increasing the emission area.
[0037] The diffusion pattern can be selected according to user needs, such as corn kernel pattern, leather pattern, etc.
[0038] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.
