Abstract
A lampshade has a body and multiple light-concentrating units formed on the body. Each light-concentrating unit has a light input recess and a light output protrusion. The light input recess is defined in one of the side of the body and has an inner wall to define a holding space in the light input recess. The light output protrusion is formed on and protrudes from the other side of the body, corresponds to the light input recess and has a smooth outer wall. Accordingly, the light emitting from an LED lamp can be further concentrated with the curvatures of the inner walls of the light input recesses and the outer walls of the light output protrusions, such that the illumination of the light emitted from the LED lamp can be improved.
