A street lamp having a tubular pole element has a projection device (6) light source (35) that is built into the pole element (4). With an optical focusing device (36) in the mast element (4), the rays of the light source are projected onto an optical deflecting mirror (20) via a focusing device (36), deflecting the light rays can be deflected through a light exit opening (5) of the pole element (4) onto a remote projection surface. A motif carrier (48) is provided in the ray path between the light source (35) and the deflecting mirror (20). The motif carrier accommodates a motif (49) to be depicted on the projection surface. An adjustable projection lens (57, 58) is arranged between the motif carrier (48) and the deflecting mirror (20), by means of which at least the sharpness of the motif (49) depicted on the projection surface can be adjusted. |
