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.

19. A system for controlling the 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; geographic location source providing geographic location data; a controller, said controller receiving at least one climate-related parameter for said geographic location; a light source generating a light output; said controller alters at least one of a 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 (20, 21, 22)
