Abstract: A reflective lampshade that is has a main body in which the cavity of the lampshade is reflective, wherein said cavity diffuse axially from the end that is close to the light source to the end that is far from the light source. The inside surface of the cavity is smeared with nano coat. The nano coat on the inside surface of the cavity has high reflectivity for visible light and infrared light, and reflect the light and heat produced by the light source to the outside of the lampshade. The nano coat is heat and fade resistant. In addition, the nano coat reduces the accumulation of dust or vapors.
