Methods and apparatus for control of illumination in an interior space
First Claim
1. A method of controlling illumination in a space, comprising:
- determining an orientation relative to the Earth'"'"'s magnetic poles or about a nadir axis of a lighting fixture;
determining a geographic location of said lighting fixture;
determining at least one climate-related parameter for said geographic location; and
adjusting at least one light output characteristic of said lighting fixture based on said orientation and said climate-related parameter.

Abstract
Methods and apparatus related to controlling illumination in a space. The method may include determining a heading of a daylight blocking element and/or a lighting fixture (301) and automatically adjusting at least one characteristic of the daylight blocking element and/or the lighting fixture based at least in part on the determined heading (305). The method may additionally or alternatively include proactively determining likely daylight conditions at a future time and beginning to adjust at least one characteristic of a daylight blocking element and/or a lighting fixture prior to the future time (202/203). Daylight blocking elements and/or lighting fixtures are also provided that may facilitate one or more aspect of the methods of controlling illumination.

10. A system for controlling illumination in a space, comprising:
-
an orientation sensor generating orientation data of at least one lighting fixture relative to the Earth'"'"'s magnetic poles or about a nadir axis; a geographic location source providing geographic location data; a controller, said controller receiving at least one climate-related parameter for said geographic location; and a light source generating a light output, wherein said controller alters at least one light output characteristic of said at least one lighting fixture based at least in part on said orientation data and said climate-related parameter. - View Dependent Claims (11, 12, 13, 14)
