Skylight having multiple stationary tilted reflectors aimed in different compass directions including inverted pyramidal or wedge geometry

摘要

A skylight system uses multiple stationary tilted reflectors aimed in different compass directions, including inverted pyramidal or wedge geometry to enhance the light output of a skylight using a conventional horizontal penetration into the building. The reflectors are made of very low cost metallized polymer film, and configured to maximize the useful lumen output of the skylight over the whole day and over the whole year. The skylight system furthermore improves the light distribution under the horizontal penetration by directing more light vertically into the working space beneath the roof penetration rather than horizontally onto walls and into the building occupants' eyes, creating glare and discomfort.

主权项

1. A skylight for providing natural lighting to the interior of a building comprising:
a transparent dome projecting above a roof of the building and defining at one end a light passage from the interior to the exterior of the building: a first stationary and tilted reflective surface defined by a vector normal to the reflective surface having a first compass direction; said vector oblique to the horizon; one or more additional stationary and tilted reflective surfaces, each of the one or more additional stationary and tilted reflective surfaces defined by a respective vector normal the respective reflective surface having a respective compass direction, said respective vectors oblique to the horizon; wherein the first and additional reflective surfaces are positioned within said transparent dome; wherein the first compass direction and the respective compass direction are not the same, and wherein the vector and respective vector have a common vertical direction wherein the first and additional reflective surfaces reflect light having an incident angle with respect to the horizon lower than a predetermined threshold into the light passage; wherein the first and additional reflective surfaces define a Y shaped wedge.
