Description

CIRCUIT BREAKER PANEL BOARD INCLUDING ILLUMINATION UNIT

CROSS-REFERENCE TO RELATED APPLICATION This application claims priority from and claims the benefit of U. S. Patent Application Serial No. 14 710,781 , filed May 13, 2015, which is incorporated by reference herein.

BACKGROUND

Field

The disclosed concept relates generally to circuit breaker panel boards, and more particularly, to circuit breaker panel boards including an illumination unit. Background Information

Circuit breaker panel boards are configured to receive numerous circuit breakers. In applications such as residential circuit breakers, the lighting in the v icinity of the circuit breaker is not independent of the circuit breaker. That is, if the power at the circuit breaker goes out, power to any lighting will also go out. Furthermore, the lighting in the vicinity of the circuit breaker may be associated with a circuit breaker in the panel board. Thus, when the circuit breaker trips, power to the lighting is cut off.

In power outages, or in the event that power is cut due to a circuit breaker tripping, residents will want to check the circuit breaker panel board to see if any of the circuit breakers have tripped. However, the area around the circuit breaker may be dark if power to the lighting around the circuit breaker is cut. Thus, a resident would need to bring a flashlight or other light source to be able to see the status of the circuit breakers in the circuit breaker panel. This creates an inconvenience for the resident, and can also create a hazardous condition if the resident attempts to ascertain the status of the circuit breakers with insufficient lighting. Additionally, lighting around the circuit breaker panel board may not be oriented in a manner that provides adequate illumination for safely approaching the circuit breaker panel board and working on circuit breakers.

There is thus room for improvement in circuit breaker panel boards. SUMMARY

These needs and others are met by embodiments of the disclosed concept, which are directed to a circuit breaker panel board including an illumination unit having lights oriented in a direction toward a circuit breaker receiving area.

In accordance with aspects of the disclosed concept, a circuit breaker panel board comprises: a housing including a door structured to open; a circuit breaker receiving area disposed in an interior area of the housing, wherein the door is structured to open to provide access to the circuit breaker receiving area; and at least one illumination unit disposed outside the circuit breaker receiving area and including at least one light oriented to provide light in a direction of the circuit breaker receiving area.

In some example embodiments of the disclosed concept, the circuit breaker panel board 1 includes only the motion sensor 14 and the illumination unit 10 is structured to turn on the lights 1 2 when the motion sensor 14 detects motion in the vicinity of the circuit breaker panel board 1 . In some other example embodiments of the disclosed concept, the circuit breaker panel board 1 includes only the photo sensor 16 and the illumination unit 16 is structured to turn on the lights 12 when the photo sensor does not detect ambient light in the vicinity of the circuit breaker panel board 1 . In yet other example embodiments of the disclosed concept, the circuit breaker panel board 1 includes both the motion sensor 14 and the photo sensor 16 and the illumination unit 10 is structured to turn on the lights 12 when the motion sensor 14 detects motion in the vicinity of the circuit breaker panel board 1 and the photo sensor 16 does not detect ambient light in the vicinity of the circuit breaker panel board 1 . In some example embodiments of the disclosed concept, the illumination unit 1 0 is structured to turn off the lights 12 a predetermined period of time after the event that cause the illumination unit 1 0 to turn on the lights has cleared. For example and without limitation, the illumination unit 10 may turn off the lights 12 a predetermined period of time after the motion sensor 1 14 last detects motion in the vicinity of the circuit breaker panel board 1 .

In some example embodiments of the disclosed concept, the circuit breaker panel board 1 further includes a power storage unit 18. The power storage unit 1 8 is a device that is structured to store power and to provide such power to the illumination unit 10 so that the illumination unit 10 may continue operating after the circuit breaker panel board 1 stops receiving external power. The power storage unit 1 8 may include any device suitable for storing power such as, without limitation, non- rechargeable batteries, rechargeable batteries, capacitors, or any other suitable device for storing power. The power storage 1 8 device may be installed in the circuit breaker panel board 1 in a variety of manners. For example and without limitation, the power storage unit 1 8 may be structured such that it may be installed in one of the slots 8 for receiving circuit breakers (e.g., without limitation, the power storage unit 1 8 is a 'dummy' circuit breaker). It is also contemplated that the power storage unit 1 8 may be independently mounted on the circuit breaker panel board 1 inside or outside the circuit breaker receiving area 6 (see FIG. 4). It is also contemplated that the power storage unit 1 8 may be an in-line device such as a power storage unit that does not have any external mounting other than two wires which may be located, for example and without limitation, at either end of the power storage unit.

In example embodiments of the disclosed concept where the power storage unit 1 8 is rechargeable, a charging unit 20 may also be included in the circuit breaker panel board 1 . The charging unit 20 is structured to charge the power storage unit 1 8. The charging unit 20 may use external power, such as line power received by the circuit breaker panel board 1 , to charge the power storage unit 1 8. The charging unit 20 may be installed in the circuit breaker panel board 1 in a variety of manners. For example and without limitation, the charging unit 20 may be structured such that it may be installed in one of the slots 8 for receiving circuit breakers (e.g., without limitation, the charging unit 20 is a 'dummy^" circuit breaker). It is also contemplated that the charging unit 20 may be independently mounted on the circuit breaker panel board I inside or outside the circuit breaker receiving area 6 (see FIG. 4). It is also contemplated that the charging unit 20 may be an in-line device or as an accessory to other equipment installed in or on the circuit breaker panel board 1 .

FIG. 3 is a stylized diagram of the front of a circuit breaker panel board in accordance with another example embodiment of the disclosed concept. The circuit breaker panel board 1 ' of FIG. 3 is similar to the circuit breaker panel board 1 of FIG. 1 . However, the circuit breaker panel board 1 ' of FIG. 3 does not include the motion sensor 14 or the photo sensor 16. Rather, the circuit breaker panel board includes a door sensor 22.

The door sensor 22 is structured to detect when the door 4 is open. The door sensor 22 may be a switch or any other suitable device for detecting when the door 4 is open. In some example embodiments of the disclosed concept, the illumination unit 10 is structured to turn on the lights 12 when the door sensor 22 detects that the door is open and to turn off the lights when the door sensor 22 detects that the door is closed. The door sensor 22, and the motion sensor 14 and photo sensor 16 of FIG. 1 , allow the illumination unit 10 to limit the amount of time that the lights 12 lights are turned on. This extends the lifespan of the lights 1 2 as well as the lifespan of the power storage unit 18.
