METHODS AND APPARATUS FOR CONTROLLING LIGHTING BASED ON COMBINATION OF INPUTS

摘要

Disclosed are methods and apparatus for lighting control based on a combination of inputs. One or more properties of light output of a lighting fixture (120A, 120B, 120C) are controlled based on local input (based on local sensor readings) and group input (provided to the lighting fixture and additional lighting fixtures) and/or one or more sensors (125A, 125B) are auto-calibrated. For example, in some embodiments a lighting controller (130A) of a lighting fixture may receive both the local input and the group input and control a dimming level of a light source (150A) of the lighting fixture based on the local input and the group input. For example, the local input may be based on input from a local sensor that is indicative of a light level near the lighting fixture and the group input may be indicative of a desired group level of dimming.
