Abstract
Methods and systems herein provide for determining lighting contributions of light fixtures to an environment. In one embodiment, a system includes a light sensor and a controller. The light sensor generates light level data based on measured light levels. The controller determines a nominal light level based on the light level data, and identifies an optical burst pattern in the light level data generated by a light fixture. The controller then determines a lighting contribution of the light fixture based on the optical burst pattern and the nominal light level.
Claims21
A for light sharping method comprising:
- receiving, at a light sensor controller, a humanly imperceptible burst pattern from a first light fixture, the burst pattern comprising a first light fixture identifier that identifies the first light fixture;
- determining a first fixture contribution value associated with the first light fixture;
- determining a first geometric relationship of the first light fixture relative to the light sensor based on the first fixture contribution value;
- associating the first light fixture identifier with the first light fixture;
- determining a first adjustment value for the first light fixture based on the first geometric relationship;
- and
- sending the first adjustment value and the first identifier to at least the first light fixture.
A for light sharping method comprising:
- receiving, at a sensor controller, a humanly imperceptible first burst pattern from a first light fixture, the first burst pattern comprising a first light fixture identifier;
- receiving, at the sensor controller, a humanly imperceptible second burst pattern from a second light fixture located within an architectural space closer to the sensor controller than the first light fixture, the second burst pattern comprising a second light fixture identifier;
- determining a first geometric relationship of the first light fixture relative to the sensor controller based on the first burst pattern;
- determining a second geometric relationship of the second light fixture relative to the sensor controller based on the second burst pattern;
- determining a first adjustment value for the first light fixture based on the first geometric relationship;
- sending the first adjustment value and the first identifier to at least the first light fixture;
- determining a second adjustment value for the second light fixture based on the second geometric relationship;
- and
- sending the second adjustment value and the second identifier to at least the second light fixture.
A light sensor comprising:
- a transceiver configured to communicate with at least a first light fixture;
- a photosensor;
- and
- a controller electronically coupled to the transceiver, and the photosensor, the controller configured to:
- receive, via the photosensor, a first humanly imperceptible optical burst pattern from a first light fixture that comprises a first light fixture identifier;
- determine the light contribution of the first light fixture from the first burst pattern;
- determine a first adjustment value from the light contribution of the first light fixture;
- associate the first light fixture identifier with the first light fixture;
- and
- send the first adjustment value and the first light fixture identifier to the first light fixture via the transceiver.
