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.

Luminaire safety system

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.

Light source alignment system

A zoom optical system includes a light source and focus, zoom, and fixed lens groups. The light source illuminates an object in or adjacent to an object plane. The focus lens group has a first positive optical power and moves to focus an object. The focus lens group has four lenses of positive, positive, positive, and negative optical power. The zoom lens group has a negative optical power and moves relative to the object plane and the focus lens group to control a beam angle while the focus lens group remains fixed relative to the object plane. The zoom lens group comprises two negative power lenses. The fixed lens group has a second positive optical power, remains in a fixed position relative to the object plane, and projects an image of the object. The fixed lens group has three lenses, comprising negative, positive, and positive optical powers.

Optical system for an automated luminaire

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.

Range sensing and safety system for a luminaire

An optical system includes a light source, a lens, and a light effect ring. The lens has first and second surfaces and receives a first light beam from the light source at the first surface and emits a second light beam from the second surface. The light effect ring includes a first plurality of light emitters emitting second light beams that obliquely illuminate the first surface of the lens and a second plurality of emitters that emit third light beams through the lens. The light effect ring may include a plurality of segments that move into and out of the first light beam, where each segment includes a first subset of the first plurality of light emitters and a second subset of the second plurality of emitters.
