DIRECT AND INDIRECT LIGHT DIFFUSING DEVICES AND METHODS |
摘要 |
Some embodiments provide a daylighting apparatus comprising an internally reflective tube configured to direct daylight from a first end of the tube to a second end of the tube opposite the first end. A diffuser can be positioned at the second end of the tube. The diffuser can comprise a first optical structure configured such that, when the daylighting apparatus is installed with the first end positioned outside a room and the second end positioned to provide light to the room, a reflected portion of the daylight is directed towards at least one upper region (e.g., a ceiling or upper wall surface) of the room and a transmitted portion of the daylight is directed towards at least one lower region (e.g., a floor surface) of the room.
