Abstract: A light fixture includes a housing with a skylight aperture, and one or more louver blades spanning the skylight aperture. When open, the one or more movable louver blades block little of the light passing through the skylight aperture; in intermediate positions, the louver blades block a portion of the light; when closed, the louver blades block most light from passing through the skylight aperture. The light fixture also includes: a dimmable artificial light source configured to project artificial light toward the illuminated space; a light sensor that detects light illuminating the space; and a control unit that is integrated with the housing and communicates with the light sensor. The light sensor detects intensity and chromaticity information of the light illuminating the space. The control unit controls position of the louver blades and brightness and chromaticity of the dimmable artificial light source, in response to the light sensor.

Abstract: A light fixture delivers light to an illuminated space. The light fixture includes a housing that defines a skylight aperture therethrough, and movable louver blades coupled within and spanning the skylight aperture. Open, the louver blades do not substantially block light through the skylight aperture; closed, the louver blades block substantially all light through the skylight aperture. In intermediate positions, the louver blades block a portion of light through the skylight aperture. The light fixture also includes a dimmable artificial light source, integrated with the housing and configured to project light toward the illuminated space; a light sensor; and a control unit that is integrated with the housing and communicatively coupled with the light sensor. The control unit receives a signal from the sensor, and controls position of the louver blades and brightness of the artificial light source, in response to at least the signal from the light sensor.
