## Abstract

A lampshade comprises a support seat, a reflector, and a cover. The support seat includes a frame and a clamping unit, the frame defining a central space, the clamping unit having two opposing connection bars attached to the frame and two grasp portions each being provided at one end of a corresponding connection bar. The distance between the two grasp portions is adjustable. The reflector is placed on top of the frame and has a reflective surface that can be fitted through the central space of the frame. The cover is placed on top of the reflector and fastened to the frame from a side opposite to the clamping unit. Accordingly, when a lighting device, such as a flashlight, is clamped by the lampshade, the light emitting from the lighting device can be reflected by the reflector to diffuse into the surrounding environment so as to increase the illuminating range.
