| 摘要 |
The present invention relates to an energy efficient lighting system, more particularly a system and method for controlling the individual power consumption and light output for each lighting luminary at a local level based upon a multitude of inputs whereby at least one of the inputs preferably is from central building control. Preferably, the ballast or lighting fixture is operatively associated with and preferably includes a microcontroller that processes all signals from sensors and other control devices including a building central control sensor that manages building power consumption and selects the most energy efficient input signal to power the lamps. The lighting system preferably includes a plurality of lighting fixtures and the lighting output of each fixture is determined on the local level by the microcontroller associated with and preferably in each circuit housing or ballast associated with the fixture.
