Abstract

An LED light bulb having separately addressable groupings of LED'"'"'s. The LED light bulb can serve as a visual indicator of emergency or non-emergency conditions by selectively illuminating groupings of LED'"'"'s in a variety of colors, each color corresponding to a predetermined condition.

Claims

1. A method for controlling a light emitting diode (LED) light bulb system, wherein the LED light system comprises a system controller having a wireless transmitter, an LED bulb apparatus comprising a wireless receiver for receiving signals from the system controller, an LED grouping of plural LEDs, control circuitry connected to the LED grouping for effecting a desired illumination condition of the LED grouping, a power supply for conditioning and powering the control circuitry, and the LED bulb apparatus connected to a power source, comprising

monitoring a telephone line using the controller to detect removing the hand set of a telephone, which is the off-hook condition;

listening on the telephone line, using the controller, for a code when the off-hook condition is detected;

receiving the code at the controller, wherein the code is indicative of a desired illumination condition;

translating the code into instructions by the controller; and

transmitting the instructions to the wireless receiver of the LED bulb apparatus via the wireless transmitter to effect the desired illumination condition.

2. The method of claim 1, wherein the LED grouping comprises plural elongated boards, the plural elongated boards being disposed generally parallel to one another.

3. The method of claim 2, wherein the LED boards comprise LEDs of a plurality of colors.

4. The method of claim 2, wherein transmitting the instructions to the wireless receiver of the LED bulb apparatus via the wireless transmitter to effect the desired illumination condition comprises transmitting the instructions to the wireless receiver of the LED bulb apparatus via the wireless transmitter to apply power selectably to the plural elongated boards.

5. The method of claim 4, wherein the LED boards comprise LEDs of a plurality of colors.

6. The method of claim 1, wherein receiving the code comprises receiving the code from a sensor.

7. The method of claim 1, wherein the code is indicative of an emergency condition and wherein transmitting the instructions to the wireless receiver of the LED bulb apparatus via the wireless transmitter to effect the desired illumination condition comprises transmitting the instructions to the wireless receiver of the LED bulb apparatus via the wireless transmitter to effect an illumination condition associated with the emergency condition.
