    Abstract: The invention relates to a low-pressure mercury vapor discharge lamp (10) comprising a metal compound which is selected from the group formed by compounds of titanium, zirconium, hafnium and their mixtures. The effect of adding the metal compound selected from said group to the gas filling of the discharge space (14) results in an increased efficiency of the low-pressure gas discharge lamp (10), because part of the emitted light from the discharge space (14) is in the visible range of the electromagnetic spectrum.

In another embodiment of the invention, the luminescent layer (16) is applied to the discharge vessel (12) of the low-pressure gas discharge lamp (10). The light emitted by the luminescent material can be mixed with the light emitted from the discharge space (14) to produce the required color.

  • Patent number: 6242851
    Abstract: This invention relates to dimmable metal halide lamps using ceramic arc tubes for the application of energy saving, mood control, and constant light output over the life of the lamp. Under dimmed conditions, as low as 50% of rated wattage, the color temperature (CCT) can remain substantially the same and be perceived by the viewer as a constant color light source. Furthermore, the invention improves the color rendering index (CRI) and the efficacy of the lamp under dimmed operation. Such improvements are provided by placing a metal shield on an end of the arc tube, whereby the emissivity of the shield is lower than the emissivity of the ceramic in the arc tube, whereby cold spot temperature in the lamp is increased, even under dimmed conditions.

  • Patent number: 6140751
    Abstract: A light source system includes a heat sink. A base connector receives electrical power. A housing is secured to the base connector. A ballast unit is secured within the housing and electrically connected to the base connector. At least one electrical component is both mechanically and electrically connected to the ballast unit. The at least one electrical component is driven by the electrical power received by the base connector. A lamp unit is secured to the housing and electrically connected to the ballast unit. An additional electrical component includes a portion which contacts an inside wall of the housing. The additional electrical component is electrically connected to the ballast unit and has a life span which decreases as an operating temperature of the additional electrical component increases. The inside wall of the housing acts as the heat sink for the additional electrical component.

  • Patent number: 6137210
    Abstract: A halogen lamp includes a bowl-shaped lamp housing, a light source, a reflector which has the light source mounted thereon and which is disposed on the lamp housing, and a heat insulating washer which is made of a heat insulating elastic material. The heat insulating washer is interposed between an upper end rim of the lamp housing and an upper end rim of the reflector in such a manner that the washer contacts the lamp housing and the reflector and that the lamp housing is spaced apart from the reflector, thereby minimizing heat transfer from the reflector to the lamp housing.

  • Patent number: 6087775
    Abstract: A lamp assembly comprises a incandescent lamp capable of generating light. The incandescent lamp comprises a incandescent lamp tube and at least one filament. The assembly also comprises a shroud separate from the incandescent lamp and mounted in communication with the lamp tube on an exterior of the incandescent lamp tube. The shroud also comprises a coating disposed on the reflecting section of the shroud for reflecting energy having predetermined wavelengths emitted by the incandescent lamp. The shroud comprises a reflecting section disposed about the incandescent lamp tube, where the geometry of the shroud generally conforms to the geometry of the at least one filament of the lamp, to reflect energy having predetermined wavelengths back substantially toward the incandescent lamp and focusing the reflected energy generally at the at least one filament of the incandescent lamp so as to increase the output from the assembly.

  • Patent number: 6057635
    Abstract: A low-pressure mercury vapor-filled discharge lamp has a glass arc tube and a glass outer tube disposed coaxially with the arc tube forming a space therebetween. A gas is disposed in the space. The arc tube contains a gas and is coated with a phosphor. A first seal hermetically seals the inner tube. A second seal seals the inner tube to the outer tube. The inner tube further contains a pair of cathodes coupled to Dumet wires extending from the interior of the inner tube to the outside of the lamp structure. The pressure in the space is set at not more than 1 Pa, which is nearly high vacuum. The longer the radial dimension of the space, the greater the heat retaining capacity and the better the temperature characteristics which can be obtained. However, by setting the pressure of the space at 1 Pa or less, the optimum heat retaining capacity can be obtained while reducing the diameter of the low-pressure mercury vapor filled discharge lamp 1.

  • Patent number: 5844364
    Abstract: A display has a matrix array of cells formed in a silicon plate and each containing a tungsten strip filament. The cells are filled with a halogen gas and are sealed by a double-glazed window with an infra-red reflecting filter to reflect heat back into the cell while allowing the transmission of visible radiation. The rear of the plate is treated to make it microporous and reduce its thermal conductivity.

  • Patent number: 5471110
    Abstract: A high pressure discharge lamp having a discharge vessel with opposing end chambers includes discharge electrodes each consisting of an open elongate filament of refractory metal wire having a plurality of succesive coil turns extending transverse to the longitudinal axis of the discharge vessel. The filament electrodes are dimensioned so that the discharge arc which terminates thereon is sufficiently retracted into the end chamber of the discharge vessel so that the fill constituents condense on a region of the discharge vessel which is primarily axially between the filament electrodes. In a favorable embodiment, the lamp is a metal halide lamp in which the electrode and the discharge sustaining fill is free of thoria and its compounds.
