Safety system and method for conventional lighting fixtures
Abstract:
A safety device is incorporated within conventional lighting fixtures, such as table lamps, floor lamps, wall lighting fixtures, ceiling lighting fixtures, chandeliers, recessed lighting fixtures, and decorative lighting fixture structural members such as ceiling medallions. The safety device incorporates several safety function response mechanisms within conventional lighting fixtures to conceal or obfuscate their presence. The safety device provides power failure lighting, alert signals in response to gas, smoke, fire, intrusion, and any other externally generated alarm signal. It may also provide night lighting. The safety device may include a safety module having a light and/or audio source, a power sensing circuit, a control circuit, and a light sensing circuit.
