A lighting fixture appears as a skylight and is referred to as a skylight fixture. First and second light engines of the fixture provide different color points, peak light intensity angles, far-field light distribution characteristics, and/or circadian stimulus values. A skylight fixture may include a sky-resembling assembly and a plurality of sun-resembling assemblies, with dedicated optical assemblies and/or light sources. A lighting fixture may include multiple waveguides that different extraction feature patterns and/or may be sequentially arranged.

A three-way bulb including light emitting diodes is used to achieve a variety of light output colors and/or intensities. In some embodiments, the inputs to a three-way bulb are configured to perform other functions, such as power a motor. In some embodiments, a bulb including light emitting diodes includes a replicable cover and/or a replicable LED. This cover may be configured to project images or support a shade made of a heat sensitive material.

A candle device with a solid candle wax and a permanent display is provided. In preferred embodiments the candle device is reusable. In other preferred embodiments the candle device contains an LED device capable of providing LED light to the candle device.

A fixture system includes a housing configured to be mounted in an upper region of a room or area. A light source is supported by the housing for providing visible light to illuminate at least a portion of the room or area. An ultraviolet radiation (UVR) system is supported by the housing for emitting UVC radiation in an upper region of the room or area. The UVR system includes at least one UVC emitting source and an optic member configured to direct UVC radiation in a pattern having a vertical width dimension that is above a threshold height from a floor or ground in the room or area.

The present invention relates to an optomechanical system (1), for dynamically controlling the photometric distribution of a luminaire, comprising a static frame (10), a light emitting substrate (50) with one or more light emitting elements (51) capable of emitting incident light (80), an optical layer (40) comprising one or more optical elements (41) capable of capturing incident light (80) and transmitting transmitted light (90), and a shifting mechanism (60) for translationally moving along at least one direction a movable element, which is chosen from either the optical layer (40) or the light emitting substrate (50). The shifting mechanism (60) comprises further one or more guiding elements (61), capable of maintaining the inclination angle between the light emitting substrate (50) and the optical layer (40) while moving the movable element (40,50). The optomechanical system is configured in such a way that the photometric distribution of the luminaire is dynamically controllable by adjusting the relative positon of the light emitting elements (51) with respect to the optical elements (41). The present invention relates also to luminaires comprising such an optomechanical system (1) and to a related method for adjusting the photometric distribution of luminaires.

A light-emitting device includes a multiplicity of light-emitting modules arranged on a first substrate. Each light-emitting module of the multiplicity of light-emitting modules includes a multiplicity of light-emitting components arranged on a second substrate. The second substrate is electrically connected to the first substrate, and includes a common primary lens for the multiplicity of light-emitting components.

A light system is provided. The light system includes a top housing, a bottom housing, and a side surface extending between the top housing and the bottom housing. An angled reflective surface is arranged between the top housing and the bottom housing and a lighting element is arranged between the top housing and the angled reflective surface. The lighting element is configured to direct light toward the bottom housing to reflect off of the angled reflective surface and out of the side surface.

An illumination device for a firearm may include a housing supporting multiple lamps. A switch actuator of the device is rotationally coupled to a rear end of the housing. A cam is coupled to the switch actuator, such that the cam rotates with the actuator, the cam having a first end including a magnet and a second end having a shaped cam surface configured to interface with a cam follower. The actuator and the cam are biased toward a neutral position. Selective rotation of the cam causes a magnet of the cam to operate one or more magnetic switches. The cam is transitionable between a plurality of discrete positions, e.g., including a pair of toggle positions in the first rotational direction from the neutral position, and a pair of momentary positions disposed on the cam in the second rotational direction from the neutral position.
