Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, specifically to a combined 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 stamping process for the high-reflectivity silver-plated aluminum sheet (which needs to be imported from Germany or Italy), resulting in significant waste, high manufacturing costs, and complex assembly. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a combined high-reflectivity folding reflector cup, which produces less waste during production, has lower production costs, and is easy and convenient to assemble.

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

[0006] A combined high-reflectivity folding reflector includes a reflector shell, a fixing plate, and multiple fan-shaped reflective sheets. The fixing plate is snapped into the reflector shell, and there is a fixed gap between the edge of the fixing plate and the inner wall of the reflector shell. The multiple reflective sheets cover the inner wall of the reflector, with the short arc edge of each reflective sheet inserted into the fixed gap. The long arc edge of each reflective sheet has a folded edge, which interlocks with the edge of the reflector shell. The reflective sheets are formed by stamping with a front-and-back arrangement.

[0007] Furthermore, it also includes a heat sink and a light source, the light source being attached to the heat sink, and the reflector cup housing covering the light source.

[0008] Furthermore, it also includes a light source pressing sheet and a housing welding sheet. The light source pressing sheet presses down on the light source and is connected to the heat sink. The housing welding sheet is fixedly connected to the reflector housing and is detachably connected to the light source pressing sheet.

[0009] Furthermore, the light source pressure plate is provided with a buckle, and the outer shell welding plate is provided with a locking hole, and the buckle is engaged with the locking hole.

[0010] Furthermore, thermal grease is provided between the heat sink and the light source.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] This utility model features a combined high-reflectivity folding reflector cup. The reflective structure is formed by splicing multiple reflective sheets, and the reflective sheets are stamped in a forward and reverse arrangement, which can reduce waste and lower production costs. The reflective sheets adopt a plug-in and snap-fit ​​installation structure, which makes assembly simple and convenient. Attached Figure Description
