  • Patent number: 9689543
    Abstract: A novelty lamp, which includes a transparent or translucent container with a top surface and a bottom surface. The bottom surface of the container is mounted in a base member. Two substances are received in the container, one of which is ferro fluid. The ferro fluid has a higher relative density at room temperature and is immiscible with the other substance. Upon application of heat, which is supplied by a light bulb mounted within the base member, globules of the substance with the initially higher relative density become less dense, rise in the other substance and flow around the container. As the globules rise toward the top surface of the container they cool, become denser and drop back down toward the bottom surface of the container. Because the ferro fluid is a magnetic liquid, magnets can manipulate it, while it changes density and flows in the container.

  • Patent number: 9595812
    Abstract: A crossed nanobeam structure for strain engineering in semiconductor devices is provided. For example, such a structure can be used for a low-threshold germanium laser. While the photonic crystal nanobeam enables light confinement in a subwavelength volume with small optical loss, another crossing nanobeam induces high tensile strain in the small region where the optical mode is tightly confined. As maintaining a small optical loss and a high tensile strain reduces the required pumping for achieving net optical gain beyond cavity losses, this technique can be used to develop an extremely low-threshold Ge laser source. Moreover, the structure can be easily integrated into electronic and photonic circuits.

  • Patent number: 8684553
    Abstract: A solar powered lighting fixture having a multi-paneled solar array that maximizes the generation of solar energy during the course of a day. The outdoor lighting fixture of the present invention includes a multi-paneled solar array housing positioned on an extension rod that includes a plurality of solar panels arranged in a slanted configuration about the periphery of the housing unit. The housing unit is positioned on the extension rod so as to be elevated above the ground but below the actual light fixture. Employing a housing unit separate from the light fixture permits a greater variety of shapes to be used for the light fixture. Moreover, it allows the individual solar panels to be positioned at an optimal angle for maximizing exposure to solar radiation. Each of the solar panels is independent of the others, charging the battery separately so as not interfere with the other solar panels.

    Abstract: A wind-driven light-emitting device comprises a housing, a first shaft sleeving member, a second shaft sleeving member and a plurality of blades. The blades are coupled to a first shaft. The first shaft has a first speed-change gear driving a second speed-change gear of a rotating second shaft. The second shaft has a magnetic element. The second shaft sleeving member has a coil connected with a circuit. The circuit is connected to a plurality of light-emitting (or light-guiding) elements arranged on the blades. When the device is windward, wind propels the blades to rotate. Thus, the magnetic element of the second shaft is rotated to induce voltage on the coil. The circuit rectifies, boosts, stabilizes and regulates the power to drive the light-emitting (or light-guiding) elements. Thereby, the present invention provides a decorative lighting effect without using any external electric power.

  • Patent number: 6257734
    Abstract: A flashlight apparatus includes a quantity of tritium within a transparent capsule for emitting light independently of any power source for helping a person locate the apparatus in the absence of substantial external light. The tritium glows in the dark for many years without any external power source. The apparatus also includes the conventional elements of a power source, a primary light source, a power circuit for electrical communication between the power source and the primary light source, a switch, and a housing containing the power source, the primary light source. The light source is preferably a light emitting diode, and may alternatively be an incandescent bulb. The light emitting diode is preferably a high intensity, low power consuming light emitting diode. The transparent capsule includes a vial containing the tritium, which capsule provides a virtually unbreakable enclosure.

  • Patent number: 6161949
    Abstract: A replica flame for simulating a flame on a wick extending from a top of a candle positioned in a candlestick. The replica flame includes a three-dimensional flame body and a rigid pin connected to extend from a base side of the three-dimensional flame body. The rigid pin includes a pointed end opposite the connection with the three-dimensional flame body, the rigid pin being able to pierce the top of the candle for releasably connecting the three-dimensional flame body to the top end of the candle at the wick. When releasably secured to the top of the candle, the replica flame creates an illusion of a flame burning on the wick of the candle thereby producing the appearance that the candle is lit. The three-dimensional flame body may include a vertical groove on one side thereof for receiving the wick of the candle and is preferably a pear shaped member having realistic colors of a natural flame duplicated thereon.

  • Patent number: 6095661
    Abstract: Improved method and apparatus for hand-held portable illumination. A flashlight and corresponding method are described. The flashlight includes a housing, a plurality of LEDs, and an electrical circuit that selectively applies power from the DC voltage source to the LED units, wherein the flashlight is suitable for handheld portable operation by a user. In one embodiment, the first electrical circuit further includes a control circuit for maintaining a predetermined light output level of the LED units as a charge on a battery varies. In another embodiment, the control circuit maintains an average predetermined light output level of the LED units as the charge on the battery cell varies by changing a pulse width or frequency as the charge on the battery cell varies to maintain a given average light output.

  • Patent number: 6092912
    Abstract: Portable, small, and light-weight radiant and/or electrical power generating sources, constructed according to the principles of this invention, comprise an air/fuel delivery device that houses a fuel canister of pressurized hydrocarbon fuel therein. The fuel canister includes a check valve that is selectively activated to release the pressurized hydrocarbon fuel to a pressure regulator and then through a venturi disposed within the delivery device. The delivery device includes an ignitor that is also activated when the fuel is released. A radiant head is attached to the delivery device and includes a luminous mantle in gas flow communication with the venturi and formed from a fibrous rare earth oxide. The head includes a lens and reflector system adjacent the mantle. Alternatively, or in addition to the radiant head, a thermophotovoltaic head can be attached to the delivery system.
