  • Patent number: 7423367
    Abstract: Broadband output high power pulsed flash lamps are useful in many applications, and when specifically optimized, can become an excellent source of ultraviolet (UV) light, which is particularly useful for photo-chemically-induced materials processing applications. Multiple factors involved with the production of high-energy light pulses can in certain cases adversely affect the ultraviolet lamp operation, thereby resulting in the development of micro cracks in lamp envelopes and subsequent limitation in lamp lifetime. Similar factors can be responsible for an increased absorption of UV radiation by lamp components and degradation of lamp efficiency. This invention describes new pulsed flash lamp designs that enable a new generation of high power and performance as required by, for example, many large-scale photo-processing applications.

    Abstract: A discharge lamp is disclosed comprising an enclosed discharge vessel for the generation of an electrical discharge and a casing made of glass which surrounds the discharge vessel. In order to achieve as constant properties as possible over the service life of the lamp, it is proposed that the glass material of the casing be doped with sodium in a concentration of at least 10 ppm, and preferably at least 30 ppm. According to a further embodiment, it is proposed that other alkali metals (except for sodium) be contained in a maximum concentration of 25 ppm. Surprisingly, by the appropriate choice of the outer bulb, not in direct contact with the actual discharge, the diffusion of sodium from the discharge vessel is reduced. In addition to this, the material of the outer bulb has a reduced inclination to crystallization.

An amount of the cerium halide is in a range from 20 wt % to 69.0 wt %, an amount of the sodium halide is in a range from 30 wt % to 79.0 wt %, and a total amount of the thallium halide and the indium halide is in a range from 1.0 wt % to 20 wt % with respect to the entire metal halides. Accordingly, the arc discharge is spread, bending of the arc discharge toward the arc tube wall is suppressed, and thus, the metal halide lamp has improved luminescent efficiency, where lowering of the flux maintenance factor is suppressed even after a long-time use, and hues of the luminescent colors are corrected.

  • Patent number: 6696788
    Abstract: An electric discharge lamp includes a light transmissive inner jacket that defines a sealed inner chamber, a first material in the inner chamber that emits light when activated, and a light transmissive outer jacket around the inner jacket. The outer jacket defines a sealed outer chamber between the inner and outer jackets that contains a second fill material. The second fill material, when activated by heat from the inner chamber when the lamp is operating, converts ultraviolet (UV) and deep blue light emitted from the inner chamber to visible light, thereby increasing an amount of visible light transmitted through the outer jacket compared to an amount of visible light transmitted through the inner jacket.

  • Patent number: 6661168
    Abstract: A miniature or subminiature incandescent lamp designed to operate with an energy source of 20 volts or less includes a filament enclosed in a first glass envelope and supported by a pair of metal contact pins. A first glass bead seals the envelope and has a pair of openings through which the metal contact pins penetrate and wherein they are hermetically sealed. A second glass bead of low melting solder glass is larger than the first bead and is sealed below the first bead and extends circumferentially beyond the perimeter of the first bead. A third bead of high melting glass is disposed below the second bead also in sealing relationship with the second bead. The outside perimeter of the third bead is substantially co-extensive with that of the second bead. A second glass envelope is sealed to the outside perimeter of the second bead and is also in abutting relationship with the third bead.

  • Publication number: 20030048052
    Abstract: A discharge lamp is disclosed comprising an enclosed discharge vessel for the generation of an electrical discharge and a casing made of glass which surrounds the discharge vessel. In order to achieve as constant properties as possible over the service life of the lamp, it is proposed that the glass material of the casing be doped with sodium in a concentration of at least 10 ppm, and preferably at least 30 ppm. According to a further embodiment, it is proposed that other alkali metals (except for sodium) be contained in a maximum concentration of 25 ppm. Surprisingly, by the appropriate choice of the outer bulb, not in direct contact with the actual discharge, the diffusion of sodium from the discharge vessel is reduced. In addition to this, the material of the outer bulb has a reduced inclination to crystallization.

  • 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.
