Abstract

The present invention describes a control circuit to be used in a lamp adapter that gives the user the ability to flash the main bulb on and off and, at the same time, flash a colored LED to indicate the purpose of the main bulb flashing. A first brief power interruption from the main switch starts the main bulb flashing and energizes a LED of a first color. A second interruption continues the flashing and energizes a LED of a second color. The intended purpose of the invention is be draw attention to a home and indicate whether or not an emergency exists.

Claims

1. A light control circuit comprising:

logic means for detecting power interruptions shorter in time than a prescribed period of time and for selecting modes of operation based on the positions of said interruptions in a series of interruptions, and for providing output signals for each of said modes;

power switching means coupled between a source of power and a load, which controls the application of said power to said load in response to said output signals from said logic means; and

,

light producing devices responsive to other of said output signals from said logic means.

2. The circuit according to claim 1, wherein said load is a light bulb.

3. The circuit according to claim 2, wherein said light bulb is caused to flash on and off in one or more of said modes.

4. The circuit according to claim 1, wherein said devices produce different colored lights.

5. The circuit according to claim 4, wherein said devices are LED'"'"'s.

6. The circuit according to claim 4, wherein said output signals cause said devices to flash on and off in one or more of said modes.

7. The circuit according to claim 3, wherein said output signals only energize said devices when said light bulb is de-energized.

8. The circuit according to claim 3, wherein said flashing occurs at different rates in different of said modes.

9. The circuit of claim 2, wherein said output signals cause said power to be applied to said bulb in a gradual manner whenever said bulb has been de-energized for a relatively long period of time.
