Patent number: 12698885Abstract: A luminaire includes a light source configured to generate an emitted light beam, and a beam reducer configured to move between a first position and a second position. In the first position, the beam reducer is outside the emitted light beam, and in the second position, the beam reducer receives the emitted light beam and occludes an outer portion of the emitted light beam to emit a reduced light beam having a smaller beam angle than the emitted light beam. The luminaire also includes an imaging subsystem configured to receive (i) the emitted light beam when the beam reducer is in the first position and (ii) the reduced light beam when the beam reducer is in the second position. The beam reducer is configured to move to the second position in response to a position of the imaging subsystem.Type: GrantFiled: March 11, 2025Date of Patent: August 4, 2026Assignee: ROBE lighting s.r.o.Inventors: Pavel Jurik, Jan Vilem, Josef Valchar
