Embodiment Construction

[0020] figure 1 A schematic diagram of a first embodiment of an adjustable reflector according to the present invention is shown. It can be seen from the figure that the adjustable reflector has an assembly seat 1 and a plurality of sheet-shaped reflectors 2 . These flake reflectors 2 are enclosed in a conical cup shape on the mounting base 1 , and the inner surface of one flake reflector 2 rests on the outer surface of the other flake reflector 2 . These flake reflectors 2 can swing relative to the mounting base 1 . Wherein the light source 3 is arranged at the center of the assembly base 1 .

[0021] In this embodiment, the flake reflector 2 and the assembly seat 1 are integrally formed of an elastic material, and the elastic material may be plastic or resin. At the same time, a folding line portion 4 is provided at the connection portion between the sheet reflector 2 and the assembly seat 1 .

[0022] Optionally, the sheet reflector 2 and the mounting base 1 according t...

Abstract

The invention relates to an adjustable reflector, which is provided with an assembling seat (1) and a plurality of independent flake reflective bodies. One end of each flake reflective body (2) is connected to the assembling seat (1), and the flake reflective bodies (2) are lapped together and can swing relative to the assembling seat (1). The adjustable reflector can freely adjust the incident angle of light rays of a light source relative to the reflective bodies as needed, so that an adjustable light spreading scope and variable light intensity are obtained. In addition, the invention further relates to a lighting device with the adjustable reflector.

Description

technical field [0001] The invention relates to an adjustable reflector. Furthermore, the invention also relates to a lighting device of the type described above. Background technique [0002] An excellent lighting device should not only have a beautiful shape, reasonable structure, high-quality electrical components, but also a high-efficiency reflector, so as to obtain high reflectivity, good light control angle and uniformity of reflection . In the prior art, an integrated lamp cup is usually used as the basic frame of the reflector, and a reflective coating made of, for example, aluminum is provided on the inner side of the lamp cup. According to different usage conditions of the user, it is usually necessary to adjust the lighting angle and the light spreading range of the lighting device. Redesigning the reflector or changing the relative position of the light source and the reflector are the most common solutions. However, this obviously increases the manufacturin...
