Abstract

An LED-based light can be installed in a conventional light fixture. The LED-based light can include a sensor operable to output a first signal indicative of whether an area of one or more of the rooms is in an occupied state or a non-occupied state, and the LED-based light can also include an LED controller operable to control at least one LED in the light in response to the first signal. Additionally, the LED-based light can include a transmitter operable to output a second signal indicative of whether the area is in the occupied state or the non-occupied state to a building environment regulator.

Claims

1. A system for use in conjunction with a conventional light fixture that is configured to receive a standardized electrical connector of a conventional light, the system comprising:

a sensor operable to output a first signal indicative of whether an area in a building is in an occupied state or a non-occupied state,

an LED-based light including;

at least one electrical connector compatible with the conventional light fixture,

at least one LED,

an LED controller operable to control the at least one LED in response to the first signal, and

a transmitter operable to transmit a second signal indicative of whether the area is in the occupied state or the non-occupied state to the regulator controller; and

a regulator controller remote from the LED-based light and is operable to control an environmental condition in the building in response to the second signal.
