    Abstract: A pulse-excited mercury-free lamp system, and method of sustaining the emission of light emission from such a lamp, is provided. The system includes a light-transmissive envelope having an inner surface and a phosphor layer coated thereon. A discharge-sustaining gaseous mixture of a noble gas, at a low pressure, and a metal halide, is retained inside the light-transmissive envelope. An electrical system provides a plurality of pulses to the discharge-sustaining gaseous mixture, resulting in a discharge, which causes the lamp system to emit light. The emission of light is maintained by turning the discharge on during a pulse width of each pulse in the plurality of pulses and by turning the discharge off during a remainder of each period in the plurality of pulses. Particularly in systems where the metal halide is indium-based, this maintains an efficient emission of light without the use of mercury.

  • Patent number: 8324790
    Abstract: A high illumination LED bulb includes a transparent lamp holder and a transparent reflective envelope having an inner face coated with a reflective membrane having light transmittance characteristic. A chamber is defined between the transparent lamp holder and the transparent reflective envelope and receives an actuator, a radiator and a light emitting module electrically connected to the actuator. The light emitting module includes a substrate disposed on the radiator and at least one LED disposed on the substrate. Light radiated from the LED is transmitted to produce superior projection beam by the transparent reflective envelope and reflected to produce inferior projection beam by the reflective membrane. Reflected halo formed by projection of the superior projection beam and the inferior projection beam on the transparent lamp holder and the transparent reflective envelope can form side projected halo, thereby radiating light with a full emission angle.

  • Patent number: 8258687
    Abstract: The present invention relates to a coaxial waveguide electrodeless lamp. The lamp is formed in analogy to coaxial waveguide cables, with an outer conductor, a central conductor, and a gas-fill vessel made of dielectric material between the outer conductor and the inner conductor. The gas-fill vessel is substantially hollow and filled with substances that form a plasma and emit light when RF radiation carried by the central conductor and ground conductor interacts with the substances in the gas-fill vessel. The present invention also relates to a leaky waveguide electrodeless lamp. The lamp is formed in analogy to leaky waveguides, with a conductor, a ground conductor, and a gas-fill vessel made of dielectric material butted against the conductor and encompassed by the ground conductor. The leaky waveguide electrodeless lamp emits light from a plasma similar to light-emission action of the coaxial waveguide electrodeless lamp described above.

    Abstract: A cold cathode lighting system comprising a cold cathode lamp with electrodes on either end of the lamp, oriented such that it includes an electrode extension in order to return the electrode to the same parallel position as the main body of the lamp. The lamp's electrodes are inserted into a casing that is comprised of a casing covers on either ends of the casing which may slid be opened. The casing covers interact with a electrode cover assembly underneath the casing covers, that allows the lamp to be inserted when the casing covers are opened. The closing of the casing covers will safely engage an interconnection with the lamp's electrodes through the electrode cover assembly.

  • Publication number: 20120218526
    Abstract: The present invention provides a high pressure discharge lamp with a start-up assist member, a lamp unit, and a lamp system that reduce breakdown voltage and provide high design flexibility by reducing restriction on a position of an adjacent conductor. In a high pressure discharge lamp 10 of a lamp unit 1, a dielectric member 20 is on the outer surface of a first sealing part 101A. The dielectric member 20 made of a titanium compound has relative permittivity higher than that of fused quartz. An upstream end of a metal wire 21 is connected to an external lead wire 102B projecting from a second sealing part 101B. A downstream end 21a is in contact with the dielectric member 20. Upon lighting of the lamp, a corona discharge occurs at the point where the end 21a is in contact with the dielectric member 20 so that breakdown voltage is reduced.
