Smoke detector, emergency light and alternate light source system

A self-contained smoke alarm detector, emergency light and alternate light source mechanism in one unit.

BACKGROUND OF THE INVENTION

Federal law requires that a smoke detector/alert unit be place in specific locations in all residential dwellings to provide warning to occupants in the event that smoke is detected. However, in the event of an electrical outage, occupants of these dwellings are usually not prepared and are given no warning. Residents can purchase an emergency light unit separately; however, this is not typically done. Generators are pricy, costly to operate and could result in fatality if not operated properly.

This unit detailed provides a smoke detector, emergency lighting and a light source in one unit. The unit eliminates the need to purchase separate smoke detector and emergency light units and requires no special electrical wiring since it plugs directly into the current hardwire smoke detector setup. A smoke detector in an existing home can be easily replaced with this unit.

Current smoke detectors/alarm system radiate a loud sound when smoke is detected; however, a hearing impaired person may not necessarily hear the sound. This unit consists of LED lights which pulsate when the sound warning is given so that a hearing impaired person will see the pulsating light and be warned of impending danger.

There still remains a need in the art for a single self contained emergency light and smoke detector system which this unit provides.

SUMMARY OF THE INVENTION

This unit is a fully functional hardwire interconnected home smoke alarm with light source. The unit is long lasting, low maintenance, and self contained.

When the electricity is on and no smoke is detected no sound will be heard and the lights will not be illuminated.

In the event of an electrical outage when no power is detected and no smoke is detected; the emergency lights will be illuminated. The alarm will not sound. When power is restored and detected the lights will go out. The lights can be turned on and off manually by a built in switch on the unit.

In the event that the electricity is on and smoke is detected, the alarm will sound and the lights will pulsate; when smoke is no longer detected the alarm sound will stop and the lights will be turned off.

In the event that the electricity is off and smoke is detected, the alarm will sound and the lights will pulsate; when smoke is no longer detected the alarm sound will stop. When power is restored and detected, the lights will go out. The lights can be turned on and off manually by a built in switch on the unit.

This unit can also be used as a continuous light source in the event of loss of electricity by simply changing out the battery periodically. The on/off switch can be wall mounted for easy access to turn on and off the light easily.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings;FIG. 1illustrates a general hardwire smoke detector circuit which includes a smoke chamber3, integrated chip2, transistor5, resistors R1, R2, R3, R4and a transistor5necessary to detect and activate the horn4and LED light signals8. This is further connected to a circuit which consist of chip6, resistors R5, R6, and R7and a transistor7which are interconnected to at least eight LED lights connected in series. The battery8is the source of electricity and can be activated and de-activated automatically or manually via the onboard manual switch controlled by the integrated chip1.

FIG. 2gives a general layout of the positions of the LEDs8A through8G for high impact light coverage. The system is designed to provide light coverage of 360° degrees and provide coverage for a standard size room. The speakers10A and10B will provide an audible warning signal. The photoelectric eye9is used to help detect the presence of smoke danger and set the warning process in motion.

The LED's will pulsate in the event of an emergency; this will serve as an added layer of warning in addition to the audible warning by the horn. The pulsating light will be a visual warning to hearing impaired occupants.

The battery source will provide the emergency source for electricity as well as function as the backup source for the operation of the smoke alarm detection.

In the absence of danger the LED lights with coverage of 360° degrees can serve as an alternate light source by simply turning the unit on or off by the manual switch on the unit. Light intensity will decrease overtime and will warrant periodic changing of battery unit to maintain intensity.

To be understood the invention is not limited to the illustration shown herein or described above. These are deemed to be merely illustrative of the best modes for carrying out the invention and are susceptible of modification of parts arrangements, sizing, timing, details of operation and technological advancements. The invention is intended to encompass all such modifications which are within the scope of the define claims.
