The lens assembly has a chamber protruding from a back surface of the wall plate, and a lens covering a front end of the chamber. The chamber is capable of receiving at least a portion of the light emitting diode, such that, light from the light emitting diode passes though the lens to illuminate an area around the switch.

  • Patent number: 7547131
    Abstract: The present invention is a low power and low heat dissipating, low illumination system that is based in an electrical box cover plate, preferably in a light switch cover plate. It allows for the maintenance of an electrical bleed current through the fluorescent light controlled by that light switch so as to keep a minimal thermal differential between the unlit and lit light. The light switch cover plate has a series of imbedded LEDs that illuminate an area all around the light switch. The unit is retrofittable on conventional light switches.

  • Publication number: 20090103329
    Abstract: An electrical device is formed by a combination of an electrical socket and a night lamp and includes a housing, a circuit board, at least one light-emitting diode, at least one socket, a sensor and a panel. The circuit board and the at least one socket are arranged inside the housing. The circuit board is electrically connected to an external power source and is also electrically connected to the at least one light-emitting diode and the sensor so that the sensor is electrically connected to the at least one light-emitting diode via the circuit board to form a circuit. The panel is releasably mounted to the housing and forms an opening corresponding to each of the at least one socket to expose the socket.

  • Patent number: 7478926
    Abstract: A lamp socket has a casing, a switching contact assembly, a stem assembly, an electric tab, a photo switch, a first electric connector and a second electric connector. The switching contact assembly is mounted in the casing and around the stem assembly. The stem assembly has a pawl. The pawl has multiple surfaces. The electric tab is mounted on two of the surfaces of the pawl and selectively contacts the switching contact assembly. The first electric connector and the second electric connector are connected electrically to the photo switch. The contact between the electric tab and the switching contact assembly switches via turning the stem assembly to turn on or off two lights. Furthermore, the lamp socket turns on one of the lights based on ambient light.

  • Patent number: 7455444
    Abstract: A multiple light source night light incorporates at least two sets of light sources to offer perfect illumination for decorative lighting and also for providing area illumination via openings, windows, holes, cut-outs, and/or light-transmitting areas of the housing. The multiple light source sets may include LED or EL elements (including sheet, wire, or tube type elements), neon bulbs or tubes, or the like. In addition, the night light may incorporate an air freshener, fan, mechanical device, O3 generator, potpourri, deodorizer elements, fragrance elements, oil, chemical compounds, sensors, heat elements, and/or switch devices to provide additional functions when the prongs are connected with a power source.

  • Patent number: 7357561
    Abstract: The device forms a single unit that includes the way by which the evaporation of active substances is achieved, as well the way that allows automatically lighting a small lamp or LED that emits a small light illuminating the container of the active substance to be evaporated. This allows one to see the contents in the dark and, in addition, constituting a light in the dark for the area surrounding the device, with the particularity that the volume of this device does not increase with respect to the devices meant to individually evaporate active substances and emit a light. The design of the device includes a general casing comprising a pinholder body for a plug and the container itself for the active substance, in such a way that the body incorporates a sensor that emits a signal for the automatic activation of the lamp or illumination LED when the light intensity is below a pre-established threshold.

  • Patent number: 7165876
    Abstract: A nightlight including a light bank having light-emitting diodes (LEDs) disposed in an array. The amount of light emitted from the light bank can be varied by engaging a switch that selects between a number of electrical pathways. The device includes a photosensitive device such as a light dependent resistor or photo-diode for switching the device on or off under varying ambient light conditions. The photo-diode may be temporarily deactivated in bright ambient light conditions to check and change the settings of the LEDs.
