Light emitting diode lamp shade, has concave cavity with inner surface and multiple annular convex mirror assembly, formed on surface, where cavity communicates with opening through which light rays of light emitting diode pass

摘要

The shade (10) has openings of different diameters permitting light rays of a light emitting diode to pass, where the openings are opposite to each other. A concave cavity (11), communicating with the openings, has an inner surface (12) and a multiple annular convex mirror assembly (13) which is formed in a coaxial manner on the surface (12). Each mirror has a trapezoidal edge and is assembled closely, without an interval, with the adjacent convex mirrors.
