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. Local inputs indicative of light levels, occupancy statuses, and environmental conditions near lighting fixtures are received, and group inputs to control the dimming state of lighting fixtures are also received. The group inputs may utilize manipulation of mains power powering lighting fixtures to indicate a dimming level. The dimming states of light sources of lighting fixtures are based on group inputs and local inputs.

主权项

1. A method of adjusting lighting at a lighting fixture based on a local input and a global input, comprising:
providing a lighting controller controlling the dimming state of a light source, the lighting controller operable to execute instructions, stored in the memory; receiving local input via a first input, at the lighting controller, the local input indicative of sensor values, wherein the sensor values are indicative of one of light levels near a lighting fixture, occupancy status near the lighting fixture, and environmental conditions near the lighting fixture; receiving group input via a second input, at said lighting controller, the group input indicative of a group lighting controller output, wherein the group lighting controller output utilizes phase cutting to indicate a dimming level to control the dimming state of the lighting fixture and at least one additional lighting fixture; and determining, utilizing said lighting controller, the dimming state of the light source of the lighting fixture based on the group input and the local input.
