Apparatus, systems, and methods for controlling light output in a lighting system based on defined light profiles are provided. In one example implementation, a light fixture can include a first light emitting diode (LED) array having one or more LED light sources and a second LED array having one or more LED light sources. The light fixture can include a power circuit configured to provide power to the first LED array and the second LED array according to a power distribution among the first LED array and the second LED array. The light fixture can include one or more control devices configured to control the power circuit to adjust the power distribution among the first LED array and the second LED array based at least in part on a signal indicative of a real time clock and a defined light profile associated with a user identified to be present in a space illuminated by the light fixture.

Configurable lighting system

Multi-function lighting fixtures are provided. In one example implementation, a lighting fixture may include an optical housing extending lengthwise between a first end and a second end. The optical housing may include a plurality of light sources disposed within an interior of the optical housing and a plurality of optical elements disposed along an exterior of the optical housing. The optical housing may also a plurality of sections defined within the interior of the optical housing. Each of the optical sections may be associated with a separate light source of the plurality of light sources and a separate optical element of the plurality of optical elements.

Each of the optical compartments may be associated with a separate light source of the plurality of light sources and a separate optical element of the plurality of optical elements.

A ceiling mounted light fixture includes a lens assembly including a central lens and a pair of side lenses. The central lens extends along a longitudinal axis, and each side lens extends parallel to the central lens and is positioned on a lateral side of the central lens. The fixture further includes at least one central light emitter for emitting light directly through the central lens and a pair of side light emitters. At least one control component operatively connected to the central light emitter and the side light emitters is configured to operate in a first mode in which the central light emitter is deactivated and the side light emitters are activated, and a second mode in which the central light emitter and the side light emitters are activated.

Medical examination light fixture

Multiphase lighting fixtures having one or more light emitting diode (LED) light sources are provided. In one example implementation, a light fixture includes one or more light sources, such as LED light sources and a power conversion circuit. The power conversion circuit includes a phase shifting transformer for implementing a phase shift between output phases of secondary windings thereof, a multi-phase rectifier having a first rectifier and a second rectifier connected in parallel for converting a multiphase input power to a rectified output or a six-pulse configuration, a zero sequence blocking transformer for reducing harmonic distortion, an interphase transformer for further reducing harmonic distortion, and a current regulator for providing a constant DC current output to the one or more light sources. In some example implementations, the DC rectified output has a voltage ripple of less than about 7%, or less than about 3%.
