Abstract: A luminaire includes a first array light engine, a second array light engine, and a control system. The first array light engine includes a plurality of light emitters and first and second lens arrays, each with pluralities of lenslets. Collimation of light rays from the first array light engine varies as the second lens array moves relative to the first lens array. The second array light engine has a linear array of light emitters and a linear lens. Collimation of light rays from the linear lens varies as the linear lens moves relative to the linear array of light emitters. The control system controls a beam angle of the light rays from the first array light engine by moving the second lens array and controls a beam angle of the light rays from the linear lens by moving the linear lens.

Abstract: 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 reflect 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.

Abstract: A luminaire includes an enclosure, an air valve, and a control system. The enclosure includes a light source, an air pressure sensor, a temperature sensor and a first opening and is otherwise sealed from external air. The enclosure may include components that modify and emit a light beam. The air valve is coupled at a second opening to the enclosure and includes a membrane covering a third opening. The membrane reduces the passage of water droplets in air passing therethrough. The air valve blocks air passage between the enclosure and the membrane when closed and allows air passage when open. The control system determines whether the enclosure is adequately sealed based on air pressure as sensed by the air pressure sensor and a temperature as sensed by the temperature sensor.

Abstract: A luminaire includes a light engine control system and a light effect control system. The light engine control system includes a power delivery and measurement (PD&M) module, a light engine power control (LEPC) module, and a light engine. The light effect control system includes a motor driver module, a position monitor module, and a mechanical and optical effect system. The PD&M module measures electric power supplied to the light engine, determines whether the measured power deviates from a desired electric power and, in response, stops delivering power to the LEPC module. The position monitor module measures a sensed position of one or more effect motors of the mechanical and optical effect system, determines whether the sensed position deviates from the desired configuration, and in response, causes a reduction in an intensity of the light beam emitted by the luminaire.

Abstract: A luminaire includes a light source emitting a first light beam with a first optical axis. An optical element of the light source alignment system receives the first light beam and emits a second light beam with a second optical axis. The second optical axis is substantially parallel to, but not coaxial with, the first optical axis. A continuously adjustable position of the optical element determines a position of the second optical axis. A method for aligning an optical axis of a light beam includes receiving a first light beam with a first optical axis; emitting a second light beam with a second optical axis that is substantially parallel to, but not coaxial with, the first optical axis; and aligning the second light beam with an optical element of an optical system by adjusting a continuously adjustable position of an optical element relative to the first optical axis.

The fixed lens group has three lenses, comprising negative, positive, and positive optical powers.

Abstract: An automated luminaire and method are provided. The automated luminaire includes a range sensing module and a control system. The range sensing module calculates a distance to a closest object in a direction that the automated luminaire is pointed. The control system reduces a beam power density of a light beam emitted from the automated luminaire when the distance is less than a threshold distance. The method includes determining whether an emitted beam power determinant of the automated luminaire has changed; if so, calculating a threshold distance from current values of one or more beam power determinants; determining whether the distance to the closest object is greater than the threshold distance; and, if not, reducing the beam power density of the light beam emitted from the automated luminaire.

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 a beam size iris 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 an aperture of the beam size iris being smaller than a predetermined threshold value.

Abstract: A luminaire includes a light emitter, an asymmetric lens, and a mechanism. The light emitter includes an exit aperture and emits a light beam having an optical axis. The asymmetric lens receives the light beam and projects a projected beam. The mechanism rotates the light emitter about an axis of rotation passing through the exit aperture, thereby moving a point of entry of the light beam into the asymmetric lens. A size and location of a hot-spot of the projected beam varies as the point of entry of the light beam into the asymmetric lens moves. The asymmetric lens includes a long axis, a short axis, and an asymmetric surface, which has a long axis parallel to the long axis of the asymmetric lens. The asymmetric surface is asymmetric in a cross-section taken in a plane perpendicular to the short axis of the asymmetric lens.
