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

Claims

1. A method for spatial orientation determination for a lightbulb, the lightbulb including a plurality of indexed light emitting elements, the method comprising:

progressing the lightbulb through an orientation pattern, comprising;

sequentially transitioning individual light emitting elements of the lightbulb from a low emission mode, to a high emission mode, to the low emission mode, wherein each light emitting element is fixed at an angular light emitting element position on the lightbulb and is associated with a light emitting element identifier;

recording an origination timestamp for each light emitting element identifier during lightbulb progression through the orientation pattern, each timestamp corresponding to operation of the respective light emitting element in the high emission mode;

receiving, from an external device, data associated with measurements of light emitted by the lightbulb during lightbulb progression through the orientation pattern, wherein each measurement is associated with a recordation timestamp;

identifying the light emitting element identifier corresponding to an origination timestamp, the origination timestamp within a threshold time duration of a recordation timestamp, the recordation timestamp corresponding to a brightest light measurement as determined from the data; and

storing the light emitting element identifier in association with an identifier for the external device.
