1. A system comprising:
- a light sensor operable to generate light level data based on measured light levels; and
a controller operable to determine a nominal light level based on the light level data, to identify an optical burst pattern in the light level data generated by a light fixture, and to determine a lighting contribution of the light fixture based on the optical burst pattern and the nominal light level.

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.

19. A light fixture comprising:
-
a light source operable to provide an optical output; and a controller operable to modulate the optical output of the light source to generate an optical burst pattern that is substantially imperceptible, to receive information for a lighting contribution of the light source at a light sensor based on the optical burst pattern and a nominal light level at the light sensor, and to adjust the optical output of the light source based on the lighting contribution. - View Dependent Claims (20, 21)
