Fire and Smoke Emergencies are the primary utilizations for the present inventive concept. Use of LEDs in the present inventive concept is preferred, however, other lighting systems could be used. The present inventive concept is configured to light a door frame once a Fire Alarm is system triggered in a commercial or residential building. The present inventive concept is to complement existing systems as well as be part of new builds. The present inventive concept can be added to an existing system, e.g., retrofit, within any structure as long as there is a power source, battery or hard wired. The lights on the door frame line the entire frame from the floor on both sides to the top and across the top of the frame. A series of doors within one building would lead people to an exterior door, leading them to safety using green lights on one side of the door frame, i.e., lights configured to emit light having a wavelength between 495-570 nm. Red lights, i.e., lights configured to emit light having a wavelength between 620-750 nm on the opposite side of the same door frames would prevent individuals from moving to interior section of a building, which potentially could cause them harm. The lights can be controlled in sections if the building is large enough. A wireless option will be available as well to insure all methods of providing power to the lights are provided.
It is an objective of the present inventive concept to provide a system which will provide an exit or doorframe lined in lights so someone trying to escape on their knees, someone in heavy smoke or the visually impaired will have a better chance of seeing the way out. Also, having a color coded path leading people to safety based on common colors aligned with the universally recognized color of danger-red and the color of go-green. The system can be placed in new buildings as systems are being placed installed or retro-fitted to tie into existing systems to enhance them. One other advantage to a system like this is the unique feature can be retro fitted into an existing system either hard-wired or with a wireless system.
The aforementioned may be achieved in one aspect of the present inventive concept by providing a system to illuminate an emergency exit pathway. The system may include a receiver in communication with a transmitter, the transmitter configured to receive a signal indicative of an event and communicate the signal to the receiver, the signal may be originated by a smoke detector, the event being an emergency event requiring evacuation of a space, the space being an enclosed space; at least one lighting device wired to the receiver, the device surrounding at least a portion of an exit for the space and configured to emit light and illuminate the portion of the exit when the signal is received by the receiver, the device being a plurality of light emitting diodes arranged along at least three sides of the exit; and/or a power source configured to power at least one of the device and the receiver, the power source being a battery pack.
The aforementioned may be achieved in another aspect of the present inventive concept by providing a method to illuminate an emergency exit pathway. The method may include the steps of receiving a signal via a receiver in communication with a transmitter, the transmitter configured to receive the signal indicative of an event and communicate the signal to the receiver, the signal may be originated by a smoke detector, the event being an emergency event requiring evacuation of a space, the space being an enclosed space; illuminating at least a portion of an exit via at least one lighting device wired to the receiver, the device surrounding the portion of the exit for the space and configured to emit light when the signal is received by the receiver, the device being a plurality of light emitting diodes arranged along at least three sides of the exit; and powering at least one of the device and the receiver via a power source configured to power, the power source being a battery pack.
