Abstract:
Lighting devices and methods for illuminating the interior of a building with natural daylight are disclosed. In some embodiments, a daylighting apparatus includes a tube having a sidewall with a reflective interior surface, an at least partially transparent light collector with one or more light turning elements, and a light reflector positioned to reflect daylight into the light collector. The one or more light turning elements can turn direct and indirect daylight into the tube so that it is available to illuminate the building. In some embodiments, the tube is disposed between the light collector and a diffuser positioned inside a target area of a building. In certain embodiments, the tube is configured to direct at least a portion of the daylight transmitted through the light collector towards the diffuser.
