Since the length of the first conductive strip end 20 is short and is not enough to contact with the connecting pin, and an insulating protective sleeve 22 is arranged outside the first conductive strip end 20, a short circuit between the first conductive strip 7 and the second conductive strip 8 is further avoided.

In one embodiment, the lampshade 1 is a transparent lampshade 1, and the transparent lampshade 1 is made of glass or plastic; the lampshade 1 and the lamp holder 2 are connected by screw threads or glued joint.
