Integration of LED lighting with building controls
First Claim
1. A system for use in conjunction with a conventional light fixture that is electrically connected to a power source and that is configured to receive a standardized electrical connector of a conventional light and with a building environment regulator that regulates at least one environmental condition in one or more rooms of a building, the system comprising:
- an LED-based light including at least one electrical connector compatible with the conventional light fixture, at least one LED, 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, 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, wherein the LED controller estimates an amount of power being used by the building and controls the at least one LED based on the estimated amount of power; and
a regulator controller in communication with the transmitter and operable to control one or more functions of the building environment regulator in response to the second signal.

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.

9. An LED-based light tube operable in cooperation with a building environment regulator that regulates at least one environmental condition in one or more rooms of a building, the LED-based light tube comprising:
-
a tube including a light transmitting portion; a pair of electrical connectors attached to opposing ends of the tube, the electrical connectors compatible with a standard fluorescent light fixture; at least one LED operable to produce light that passes through the light transmitting portion of the tube; 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; an LED controller operable to control the at least one LED in response to the first signal, wherein the LED controller estimates an amount of power being used by the building and controls the at least one LED based on the estimated amount of power; and a transmitter operable to output a second signal indicative of whether the area is in the occupied state or the non-occupied state to the building environment regulator. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
