Description

Technical Field

[0001] This utility model relates to the field of lighting accessories technology, specifically to a high-reflectivity folding reflector. Background Technology

[0002] A reflector cup is a reflective device that uses a point light source as its core and a cup-shaped reflector to focus light over a long distance. It is mainly used to control the illumination distance and area of ​​the main light spot. Its core design parameters include the position of the light source, the aperture diameter, and the light emission angle. It achieves the focusing function through a parabolic curved surface and is commonly found in flashlights, searchlights, LED streetlights, and projection equipment.

[0003] Reflectors can be categorized into three types based on their material: metal, plastic, and glass. Metal reflectors offer high temperature resistance and, under automated spinning equipment, allow for excellent precision control and consistency, making them suitable for portable and high-power, high-temperature lighting fixtures. Plastic reflectors are low-cost and meet safety regulations, making them suitable for medium- and low-temperature applications. Glass reflectors offer the best precision and temperature resistance but are fragile and expensive, and are primarily used for fixed equipment. Metal reflectors require spinning, stamping, and polishing processes, offering advantages such as moderate cost and temperature resistance, making them commonly used in flashlights and high-power, high-temperature lighting fixtures. Current high-reflectivity folding metal reflector structures require the use of a single, integral stamping process for the high-reflectivity silver-plated aluminum sheet (which needs to be imported from Germany or Italy), resulting in significant waste and high manufacturing costs. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this invention provides a high-reflectivity folding reflector cup, which produces less waste and lowers production costs during manufacturing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-reflectivity folding reflector cup includes a horn-shaped outer shell and multiple fan-shaped reflective sheets formed by stamping in a forward and reverse arrangement. The outer shell has a lower edge and an upper edge. The lower edge has multiple mounting holes. The short arc edge of each reflective sheet has a lower protrusion and the long arc edge has an upper protrusion. The multiple reflective sheets are closely arranged on the inner wall of the outer shell. The lower protrusion is inserted into the mounting holes. The upper protrusion has a folded edge, which is interlocked with the upper edge.

[0007] Furthermore, the reflective sheet is a silver-plated aluminum sheet.

[0008] Compared with the prior art, the present invention has the following beneficial technical effects:

[0009] The high-reflectivity folding reflector of this invention has a reflective structure made up of multiple reflective sheets spliced ​​together. This structure is beneficial for stamping production, can reduce waste, and lower production costs. Attached Figure Description

[0012] Figure 3 This is a structural diagram of the reflector sheet of this utility model.

[0013] Figure 4 This is a schematic diagram of the stamping process of the reflective sheet of this utility model.

[0014] The components are: 1. Outer shell; 11. Lower edge; 12. Upper edge; 13. Mounting hole; 2. Reflector; 21. Lower protrusion; 22. Upper protrusion; 23. Folded edge. Detailed Implementation

[0015] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Example 1

[0017] like Figure 1-3 As shown, a high-reflectivity folding reflector cup includes a horn-shaped outer shell 1 and multiple fan-shaped reflective sheets 2 formed by stamping in a forward and reverse arrangement. The outer shell 1 has a lower edge 11 and an upper edge 12. The lower edge 11 has multiple mounting holes 13. The short arc edge of the reflective sheet 2 has a lower protrusion 21, and the long arc edge has an upper protrusion 22. The multiple reflective sheets 2 are closely arranged on the inner wall of the outer shell 1. The lower protrusion 21 is inserted into the mounting hole 13, and the upper protrusion 22 has a folded edge 23, which is interlocked with the upper edge 12. The reflective sheet 2 is preferably a highly reflective silver-plated aluminum sheet.

[0018] The production and installation method of the high-reflectivity folding reflector of this utility model is as follows:

[0019] First, spin-form the outer casing 1, and punch mounting holes 13 at the lower edge 11. Then, anodize the surface of the outer casing 1. Next, take high-reflectivity silver-plated aluminum sheets and arrange them in opposite directions (see reference). Figure 4Multiple fan-shaped reflective sheets 2 are stamped out by multiple layers of film; finally, the reflective sheets 2 are installed on the outer shell 1, the lower protrusion 21 is inserted into the mounting hole 13, and the upper protrusion 22 is engaged with the upper edge 12 through the folded edge 23. The reflective sheets 2 are then formed by a jig, which is consistent with the generatrix arc of the spun outer shell 1, so that the reflective sheets 2 are attached to the inner wall of the outer shell 1 to ensure the reflection angle of the reflector cup.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
