Described are an improved automated luminaire and automated luminaire system with both a spot light and wash light mode of operation, which employs an improved beam shutter blade system that serves as framing shutters in spot light mode and barn doors in wash light mode.

Disclosed is an LED light source automated luminaire with a multi sided elongated light collimator/mixer/integrator with receiving lens and output lens both with spill shields and where the receiving spill shield is nesting in the output spill shield. The elongated integrator has a square input cross-section and a hexagon or octagon output cross section and is tapered so that the input cross section is smaller than the output cross section.

A light fixture has an elongated track comprising an upper channel comprising a first wall having a first slot and a second wall having a second slot. The assembly has a support assembly comprising a base and a swivel arm rotatably attached to the base at a swivel. The base comprising a first flange received in the first slot and a second flange received in the second slot, said base extending across the upper channel. The swivel arm has a first end and a second end. The swivel is disposed at the first end and a cable connector is disposed at a second end of the swivel arm. The cable connector receives a cable therein.

A lighting device includes a baffle extending about an optical axis to surround a light source, and a reflector module connected to the baffle. The reflector module includes a main reflector having a light exit opening from which a light output of the lighting device is projected towards a target area, the optical axis passing through the opening, and reflective surfaces adjacent to the opening for reflecting light incident thereon away from the opening. The reflector module further includes auxiliary reflectors for adjusting the shape of the light output of the lighting device. Each auxiliary reflector has a reflective surface, and is moveable relative to the main reflector between a stowed position and a deployed position in which at least part of the reflective surface of the auxiliary reflector is exposed, by the opening of the main reflector, to reflect light incident thereon away from the target area.

A plant growing apparatus including a chamber for growing plants. The chamber includes a base for receiving the plants, a lid movably mounted in relation to the base having an outer face and an opposite inner face, and a collapsible screen having an inner surface and being mounted between the base and the lid for closing the chamber. The collapsible screen is operable between an extended configuration and a collapsed configuration. The collapsible screen is configured to collapse upon approaching the lid towards the base and to extend, upon distancing the lid away from the base. The plant growing apparatus also includes a horticultural lamp mounted on the inner face of the lid.

An arrangement (10) for generating a light effect (26) includes an obscuration sheet material (11) and a divergence sheet material (12) arranged in spaced apart relation to a rear side (23) of an effect sheet material (13). The obscuration sheet material (11) has at least one transmission region (17) and at least one shielding region (18). On the light entry side (15), which faces away from the effect sheet material (13), light (L) impinges on the obscuration sheet material (11) and is severely reduced or completely shielded in shielding region (18), while light (L) passes through the at least one transmission region (17). By means of the divergence sheet material (12), divergent light rays (LD) are produced at the corresponding transmission region (17), which divergent light rays impinge on the rear side (23) of the effect sheet material (13) and generate a light effect (26) for a viewer (25) looking at the viewing side (24).

A light source includes: light-emitting elements of different colors, forming a light-emitting element group; a light-emitting element base on which the light-emitting elements are placed in a way that a main optical axis direction intersects a placement surface of the light-emitting element base; a reflection unit including a reflection surface configured to narrow light emitted from the light-emitting element group, a front-side opening portion formed on a front side of the reflection unit in the main optical axis direction, and a rear-side opening portion formed in a rear side of the reflection unit in the main optical axis direction; and a diffusing portion placed in front of the reflection unit in the main optical axis direction, and configured to diffuse the light. In the reflection unit, an area of the front-side opening portion is smaller than that of the rear-side opening portion.

A Shabbat bulb and a related method is provided allowing control of illumination without electrical intervention by a person observing strictures of Shabbat orthodox Jewish law. The bulb includes a housing covering an electrically operated light source. A blackout mechanism is attached to but easily separable from the housing and has no operating connection with electrical circuitry. The mechanism includes a disc having at least one disc aperture through which light from the light source is transmitted; and an arm projecting radially outward from the disc. Manual movement of the arm from an open position to a closed position respectively allows full or totally no illumination to exit the bulb via the disc.

A luminaire includes a light source and a framing shutter system. The light source is configured to emit a light beam. The framing shutter system includes an aperture that is configured to receive the light beam. The framing shutter system further includes a plurality of shutter blades configured to be positioned across the aperture and mask a portion of the light beam. Each of the shutter blades includes a blade substrate material having a front surface that is configured to receive the light beam and a rear surface on an opposite side of the blade substrate material from the front surface. The front surface of each shutter blade includes a first coating that is configured to reflect one or both of light and heat. The rear surface of each shutter blade may include a second coating configured to reduce reflection of light from the rear surface.
