  • Patent number: 6527400
    Abstract: An electroluminescent supplementary lighting device having three-dimensional configuration will typically have a curved front face, or a partial conical front face; or have the configuration of a truncated pyramid. The entire front face is light emitting when the device is plugged into a wall receptacle. The front face is translucent, and an electroluminescent panel having substantially the same configuration as the front face underlies the front face within the attached interior of the lighting device. A connection tab extends from an edge of the electroluminescent panel into an enclosed volume within the lighting device, where connections are made to electrical prongs so as to provide a voltage across the electroluminescent phosphor lying within the electroluminescent panel between the electrically conductive front and back sheets.

  • Patent number: 6431719
    Abstract: A self-contained night light is disposed in a housing containing spaced-apart male AC prongs the mate with an AC socket. The housing contains an array of differently colored, preferably light emitting diode. Light sources that can dynamically output different patterns of differently colored light in response to drive signals. A microcontroller executes a sequence of instructions causing the controller to output different sequences of signals that are coupled to a driver unit that drives the light sources. The result is that the array dynamically produces different patterns of differently colored light. A user operable control allows a viewer to “freeze” any desired pattern of light, such that until reset, the night light will continue to output a static pattern of colors. The night light may include a manual or light-sensing ON/OFF switch.

  • Patent number: 5670776
    Abstract: An improved wall plate incorporating an electroluminescent lamp for providing illumination to the immediate area proximate the wall plate. The electroluminescent (EL) panel is activated and deactivated by a photoconductive cell, in response to the intensity of ambient light falling on the wall plate. A further embodiment provides for an easily accessible regulating means for regulating the intensity of the light emitted by the EL panel.

  • Patent number: 5622424
    Abstract: A picture holder is disclosed for bayonet connection to a standard right angle wall plug mounted night light. An opaque frame is provided having a transparent convex outwardly exposed arcuate front wall with a defined frame periphery. A corresponding arcuate slot in the front top of the frame provides for insertion and removal of pictures to be displayed. A translucent backing is provided to the frame having an arcuate profile opposite and complimentary to the arcuate transparent profile of the transparent cover. The translucent backing has a profile to intimately surround the partial profile of the lamp to which the frame mounts. The frame with picture mounted can be inserted to the wall plug mounted bulb so that a first portion of the bulb is exposed to the enclosed interior of the frame and a second portion of the bulb is exposed to the wall of a wall mount plug immediately behind the frame. The frame includes as the base portion thereof the bayonet connection to the light.

  • Patent number: 5544025
    Abstract: A nightlight is disclosed which includes, in a single unitary fixture, an outlet cover plate having a rearward extending set of male contacts which cover and plug directly into a first set of the duplex outlet receptacle contacts and a nightlight portion having extended life characteristics and extending forward of the cover plate. The unit simply and easily plugs into a standard duplex outlet. The plug may extend into a first one of the receptacles and the forward extending portion covers a second one of the receptacles. The cover plate and nightlight combination is simply secured with at least one ordinary screw fastener in such a manner as can be accomplished with a minimum level of skill, well within that of the ordinary homeowner.

  • Patent number: 5481442
    Abstract: A night light integral with a low profile cover plate assembly for electrical wall outlets utilizes two parts, a wall plate and a cover plate. The wall plate has a flat rear panel which is attached to the wall outlet, lies against the wall and includes peripheral lips holding a plurality of detent ridges. The cover plate includes the night light assembly which, in turn, includes power blades engaging the slots of the wall outlet to energize a night light bulb. Light escapes from underneath the cover plate through clear plastic lenses filling openings in the cover plate. Snap action projections on the inner surfaces of the cover plate periphery engage the retention ridges on the outer surfaces of the wall plate to ensure that the cover plate night light is attached to the wall plate by forces other than simply the friction of the power blades in the outlet slots. The cover plate may simultaneously used to cover a low profile plug in the other outlet slots of a standard duplex wall outlet.
