  • Patent number: 9693026
    Abstract: In a projection type display apparatus, a lighting device includes two reflection type cutoff filters (first cutoff filter and reflective second cutoff filter) which block out ultraviolet range light on an output optical path from a light source. A cut on wavelength of the second cutoff filter on the front side is longer than that of the first cutoff filter on the rear side. The two cutoff filters are formed on planar-shaped first faces of a first integrator lens and a second integrator lens. For this reason, both input faces of the two cutoff filters are orthogonal to an apparatus optical axis.

    Abstract: Methods and apparatuses for starting a discharge lamp are disclosed. In some embodiments, a lamp has an outer envelope connected at one end to a base and enclosing multiple double-ended arc tubes. Each arc tube is electrically connected at one end to an electrical lead positioned proximate the base of the lamp and at the other end to an electrical lead positioned proximate the distal end of the envelope. A voltage pulse is applied to the electrical lead positioned proximate the distal end of the envelope. Random starting of the arc tubes may thus be effected so that each arc tube is about equally likely to start, promoting uniformity of arc tube usage and long lamp life. Multiple arc tubes may be bulbous and staggered in axial displacement for space efficiency, and a diffusing shroud may improve optical characteristics. A heat barrier may facilitate fast restrikes.

  • Patent number: 8110972
    Abstract: A composite High Intensity Discharge (“HID”) arc tube includes a discharge tube and two outwardly extending tubes. The discharge tube is a composite two-layer shell with an outer of fused quartz glass or Vycor quartz glass, and a layer of translucent polycrystalline alumina (“PCA”). The outwardly extending tubes are made of fused quartz glass or Vycor quartz glass, and a layer of polycrystalline alumina is applied at ends of the outwardly extending tubes close to an arc chamber. After the arc tube is sintered at a high temperature, the electrode is sealed by being separated into two segments. The first segment of the outward extending tube applied with PCA is sealed by glass solders, and the second segment of quartz glass is sealed by a molybdenum foil under pressure.

  • Patent number: 8063565
    Abstract: A lamp and methods of forming are shown. In one example, a dielectric layer is formed over a gap between conductors in a plasma lamp. Electric arcing is reduced or eliminated, thus allowing tighter gaps and/or higher voltages. In one example a glass frit method is used to apply the dielectric layer. A lamp is shown with a barrier layer that prevents tarnish such as tarnish from sulfur exposure. The barrier layer reduces or prevents degradation of the lamp due to conversion of a conductor material to non-conductive tarnish material.

  • Patent number: 8049425
    Abstract: A lamp is provided having an arctube having a light-transmitting envelope. The arctube is surrounded by a gaseous medium confined by a containment envelope such as a hermetic shroud. The gaseous medium is preferably He or H2 or Ne or another gas whose thermal conductivity is greater than that of N2 at 800° C., or a mixture thereof, to help cool the arctube. The inside and/or outside of the shroud may be coated with a diffusion barrier. To help cool the hot spot of the arctube the gap between the shroud and the envelope can be made small, the portion of the shroud wall near the arc can be thickened, the arctube can be offset above the longitudinal axis of the shroud, and the return lead of the arctube can be located between the shroud and the arctube.
