Switch cover plate providing automatic emergency lighting
TLDR
In this paper, a wall mounted cover plate (40) conceals an electrical circuit (50) capable of sensing the field provided by a covered switch (30) or electrical socket circuit.Abstract:
A wall mounted cover plate (40) conceals an electrical circuit (50) capable of sensing the field provided by a covered switch (30) or electrical socket circuit. When power is lost at the wall circuit the electrical circuit (50) senses the loss of power and activates one or more LEDs (90A) to provide emergency illumination. The electrical circuit (50) is self contained and does not require stand-by energy so that the batteries (58) are long lasting.read more
