Abstract: A light projector (10) for projecting a beam of light (19), which comprises: a housing (16) containing a light source (40) and a projector lens (18), and a drive motor (42), and defining an aperture; and a main shaft (20) extending through the aperture. A flexible and resilient elastomeric coupling (30) links the main shaft (20) to the housing (16) at the aperture. The drive motor (42) is coupled by a drive mechanism (50) to the main shaft (20), so that activation of the drive motor (42) moves the orientation of the housing relative to the longitudinal axis of the main shaft (20). Consequently a light beam (19) from the projector (10) sweeps out a conical surface in space around that longitudinal axis.
