Directional lighting system and method

Abstract

The method of spatial lightbulb operation includes determining the position of the lightbulb relative to a physical space, detecting a contextual event, determining a spatial lighting pattern associated with the contextual event, and selectively controlling lightbulb light emitting elements based on the position of the lightbulb and the spatial lighting pattern. A lightbulb including: a plurality of individually controlled light emitting elements mounted in fixed, predetermined positions on the substrate; a light sensor mounted to the substrate; a wireless communication module; and a processor configured to: index each light emitting element; progress each of the plurality of light emitting elements through an orientation pattern; associate a reference point on the lightbulb with an external reference point; and selectively operate individual light emitting elements of the plurality according to lighting instructions, based on a relationship between the reference point on the lightbulb and the external reference point.

We claim: 
     
         1 . A method for controlling lightbulb operation, comprising:
 determining a lightbulb orientation for the lightbulb within a venue, the lightbulb comprising a plurality of light emitting elements, each with a predetermined spatial position on the lightbulb;   determining a spatial lighting pattern for the venue, the spatial lighting pattern comprising a set of light parameters for a target location within the venue;   identifying a light emitting element from the plurality of light emitting elements based on the lightbulb orientation, the predetermined spatial positions, and the target location; and   selectively operating the identified light emitting element based on the set of light parameters.
