Abstract

A reflective illumination structure is provided. It includes a heat dissipation base, a lighting unit disposed at a top of the heat dissipation base, and a reflective lampshade enclosing the lighting unit. An inner wall of the reflective lampshade is provided with a specular reflection arc surface disposed at a bottom end of the inner wall of the reflective lampshade and a diffuse reflection arc surface disposed at a top end of the inner wall of the reflective lampshade. A part of light emitted from the lighting unit is directly emitted to the diffuse reflection arc surface, and another part of the light is reflected by the specular reflection arc surface and then is emitted to the diffuse reflection arc surface. The light reflected by the diffuse reflection arc surface is emitted through a bottom of the reflective lampshade and forms a uniform rectangular light spot.
