Abstract
A projecting lamp for projecting images to create visual and decorative effect is provided. The projecting lamp mainly includes a lamp cylinder mounted on a supporting structure. A projecting structure is mounted in a front opening of the lamp cylinder and includes a focus control bar. By rotating a threaded body of the focus control bar, a distance between a projecting lens located at a front of the projecting structure and a projecting picture located at a rear of the projecting structure is finely adjusted to enable projection of a magnified and clear image. The lamp cylinder is adjustable in its elevation angle and its angular position in a plane. The whole projecting lamp may be quickly disassembled for easy storage and conveyance.
