  • Lighting system combining natural and artificial light
    Patent number: 8569977
    Abstract: A system for lighting an interior of a building according to one example embodiment includes a curb positioned on an exterior of the building for receiving natural light. A light duct is positioned within the curb having a reflective inner surface for transferring the natural light. A light fixture is connected to an outlet of the light duct such that both natural light and artificial light are emitted from the light fixture to the building interior. A photo sensor is positioned in the building interior to sense an illumination level therein. A controller in communication with the photo sensor and the light fixture is programmed to adjust the amount of light emitted by a dimmable light source in the light fixture in response to fluctuation in the illumination level sensed in the building interior in order to maintain a desired illumination level.
