At least one embodiment in accordance with the present disclosure relates generally to power devices, such as power strips, power distribution units, and uninterruptible power supplies (UPS), having illuminated outlet openings.
2. Discussion of Related Art
Many electronic and electrical systems, such as computer and home entertainment systems require that electrical power be supplied to various components of the system. The use of power devices, such as power strips, power distribution units, and uninterruptible power supplies (UPS) to supply power is known.
Power strips are a strip of power outlets that receive power from a power source and allow multiple devices to be plugged into the various outlets on the strip to distribute that power. In some instances, the power strips have a flexible cable with a plug attached to be engaged into a power source, such as a wall outlet. In other instances, the power strip has a “wall-tap” type design where the device is connected directly to a wall outlet duplex without the use of a cord. In the “wall-tap” design, the plug has prongs are flush against the rear housing of the unit, and no cord or cable is necessary. In addition to providing power to the devices, the power strip may also provide power surge protection. Power distribution units (PDU) often refer to large industrial power strips constructed for use in data centers.
Uninterruptible power supplies provide regulated, uninterrupted power for sensitive and/or critical loads, such as computer systems and other data processing systems, is known. A number of different UPS products are available including those identified under the trade name Smart-UPS® from American Power Conversion Corporation of West Kingston, R.I. In a typical UPS, a battery is used to provide backup power for a critical load during blackout or brownout conditions.
When power devices are located in dark room, or in places where they may have limited visibility, such as below a table or behind a shelf, identifying the outlet locations may be difficult, making it challenging to engage a plug into the outlet. Aspects in accord with the present invention provide power devices with illuminated outlet openings that provide better recognition to allow a user to identify an outlet and engage it with a plug.
According to principles of the invention, a power device includes a housing, a power input interface to the housing, and a plurality of power outlets on the housing for distributing power from the input. Within the housing of the power device, a printed circuit board has at least one LED positioned adjacent to at least one of the plurality of outlets to illuminate the openings of the outlets from within the interior housing.
The power device could be any electronic device that provides power through multiple outlets. Examples of power devices include, but are not limited to, surge protectors, power conditioners, power strips, power distribution units (PDU), or uninterruptible power supplies (UPS).
In embodiments consistent with principles of the invention, printed circuit boards in the power devices may have LEDs positioned adjacent to each of the plurality of outlets in the power device. In some embodiments, the LED in the power device may be activated by a light sensor. The power device may include a battery, from which the LEDs draw power, and in some circumstance may also provide battery power for a UPS.
In some embodiments, the outlets of the power devices are located on a face of the housing, the face being formed from non translucent material. In other embodiments the entire housing of the power device is formed from non-translucent material.
The accompanying drawings are not intended to be drawn to scale. In the drawings, each identical or nearly identical component that is illustrated in various FIGs. is represented by a like numeral. For purposes of clarity, not every component may be labeled in every drawing. In the drawings:
At least some examples in accordance with the present invention relate to systems and processes for providing improved control, monitoring and/or configuration of uninterruptible power supplies.
The aspects disclosed herein in accordance with the present invention, are not limited in their application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. These aspects are capable of assuming other examples and of being practiced or of being carried out in various ways. Examples of specific implementations are provided herein for illustrative purposes only and are not intended to be limiting. In particular, acts, elements and features discussed in connection with any one or more examples are not intended to be excluded from a similar role in any other examples.
In some embodiments, the LEDs may be powered through AC power from the input, or alternatively through battery power (the power path through the printed circuit board 130 not shown). In other embodiments, the LEDs may draw power and continuously illuminate the outlet openings, or they may be switched by a light sensor (not shown in
By having the openings of the outlets 125a-c on the surge protector 100 illuminated, a user may be able to easily locate the outlets in the dark, or in some visually obscured location, such as underneath a table or desk. This prevents a user from having to resort to the risky “feel and plug” approach that can result in electric shock. Further, by specifically lighting the outlet openings, rather than the entire surge protector 100 or outlet faceplate 120, specific visual guidance is provided for enabling a user to more easily engage a plug into illuminated openings of the outlets 125a-c. In some embodiments, the faceplate 120 is made of non-translucent material to allow the illuminated holes of the outlet to have more visual definition. In other embodiments the entire housing is made of non-translucent material to further highlight the outlet hole openings. It is preferably that the LEDs are not of such high intensity brightness to illuminate the openings in manner that the distinct holes of the outlets are not obscured by the brightness.
By having the openings of the outlets 325a-c on the power strip 300 illuminated, a user may be able to easily locate the outlets in the dark, or in some visually obscured location, such as underneath a table or desk. This prevents a user from having to resort to the risky “feel and plug” approach that can result in electric shock. Further, by specifically lighting the outlet openings, rather than the entire power strip 300 or outlet faceplate 320, specific visual guidance is provided for enabling a user to more easily engage a plug into illuminated openings of the outlets 125a-c.
