US Patent 7506990 Switchplate area light

A light emitting diode (LED) and associated driver circuit wherein the LED is mounted on the front of a switchplate and the driver circuit on the back of the switchplate. The LED is mounted at a downward angle on the outside of the switchplate so as to light a pathway beneath the switchplate. The drive electronics are designed to work with a return path through an electrical load. Additionally, the LED driver circuit is designed to allow operation of the LED with both resistive and reactive loads controlled by the switch to which the switchplate is connected. The device is also designed to be connected to any electrically valid combination of 2-way, 3-way, and 4-way switches either singly or in combination.
