Power supply devices with illuminated receptacles
The present invention provides power supply devices having illuminated receptacles. Some or all of the receptacles are encircled or otherwise circumscribed by a lighting member. The lighting member may be a continuous strip of material, such as an electroluminescent laminate. The lighting member may illuminate the receptacles regardless of whether the receptacles themselves are currently powered. Thus, although the power supply device is in a no or low light environment, or when the device is plugged in but is turned off, a user may easily identify where the receptacles are, which ones are available, and which equipment is plugged into which receptacles. The lighting member may be color coded according to a surge protection rating for the power supply device. In this case, the user can immediately identify which power supply devices have a given surge protection, and can therefore distinguish among different power supply devices having similar physical configurations.
1. A power supply device, comprising:
a housing member having a side including an on/off switch and a plurality of receptacles adapted for electrical connection to external electronic equipment;
a power connector operable to electrically couple to a power source, the power connector having a hot lead, a neutral lead and a ground lead;
a first power plate electrically coupled to the hot lead of the power connector and operable to provide a hot connection to the plurality of receptacles;
a second power plate electrically coupled to the neutral lead of the power connector and operable to provide a neutral connection to the plurality of receptacles;
a ground plate electrically coupled to the ground lead and operable to provide a ground connection to the plurality of receptacles; and
a surge protection device electrically coupled to the first and second power plates and having a light means for identifying a surge protection rating of the surge protection device and for illuminating at least some of the plurality of receptacles;
wherein the light means completely circumscribes all of the receptacles.
2. The power supply device of claim 1 , wherein the light means provides a color identification associated with the surge protection rating for distinguishing from similar power supply devices having different surge protection ratings.
3. The power supply device of claim 1 , wherein the light means includes an illumination portion of an electroluminescent material.
4. The power supply device of claim 3 , wherein the electroluminescent material is a single continuous sheet of material.
5. The power supply device of claim 3 , wherein the light means further comprises a cover portion on the side of the housing member, the cover portion overlaying the electroluminescent material.
6. A power supply device, comprising:
a housing member having a side including an on/off switch and a plurality of receptacles adapted for electrical connection to external electronic equipment;
a power connector operable to electrically couple to a power source, the power connector having a hot lead, a neutral lead and a ground lead;
a first power plate electrically coupled to the hot lead of the power connector and operable to provide a hot connection to the plurality of receptacles;
a second power plate electrically coupled to the neutral lead of the power connector and operable to provide a neutral connection to the plurality of receptacles;
a ground plate electrically coupled to the ground lead and operable to provide a ground connection to the plurality of receptacles; and
a surge protection device electrically coupled to the first and second power plates and having a light means for identifying a surge protection rating of the surge protection device and for illuminating at least some of the plurality of receptacles;
wherein the light means substantially encircles selected ones of the receptacles.
7. The power supply device of claim 6 , wherein the light means provides a color identification associated with the surge protection rating for distinguishing from similar power supply devices having different surge protection ratings.
8. The power supply device of claim 6 , wherein the light means includes an illumination portion of an electroluminescent material.
9. The power supply device of claim 8 , wherein the electroluminescent material is a single continuous sheet of material.
10. The power supply device of claim 8 , wherein the light means further comprises a cover portion on the side of the housing member, the cover portion overlaying the electroluminescent material.
