Abstract
Disclosed is a projection ring, including an annular body; a telescopic portion disposed on the annular body; and a projector disposed on the telescopic portion. The location of the projector on the projection ring is easily adjustable, thus it's convenient to adjust the size of the picture as projected or the projection angle.
