    Abstract: An irradiation device is provided having a housing having an interior chamber and an infrared emitter arranged therein. The infrared emitter has an emitter tube made of high silica content glass having a round cross section and a defined outer diameter. Electrical connection elements are made of a metallic material and led out from the emitter tube through a seal. In order to provide the emitter with a long service life and potentially higher output, which is also suitable for being enclosed by a seal that separates the regions of different media, temperatures, or pressures, the emitter tube end also has a round cross section and the defined outer diameter. Between the electrical connection element and the emitter tube there is a seal containing at least one transition glass, which has a thermal expansion coefficient lying between that of the metallic material and that of the high silica content glass.

  • Patent number: 8766537
    Abstract: Methods for improving the efficiency of infrared (IR) halogen lamps and IR halogen lamps having improved efficiency are disclosed. In a method of aligning a filament in a lamp body, the lamp body having the filament therein is rotated, and tubular end portions are heated and necked down which may assist in positioning the filament within the lamp and reduce end losses. IR halogen lamps formed from glass tubes having an OD less than 5 mm are also disclosed. The reduced diameter of the glass tubing increases the surface area for IR energy reflection and reduces end losses. Spuds or beads may be used to position the filament within the lamp.

  • Patent number: 7402952
    Abstract: The incandescent lamp, which uses a carbon cycle process, is equipped with a luminous body which, together with a fill, is introduced in a vacuum-tight manner into a bulb, the luminous body including a metal carbide, the melting point of which is above that of tungsten. The distance between the luminous body and the wall of the bulb is less than 18 mm, with a first cycle process, which is attributed to the carbon, being effected by the use of carbon and hydrogen as fill additive, and a second cycle process, which is attributed to the metal, being effected by the use of halogen.

  • Publication number: 20080074057
    Abstract: The invention relates to lamps, and particularly to incandescent electric lamps. incandescent electric lamps operating at mains voltage are known for decades and are widespread throughout the world. However, this type of lamp is not power efficient. It is suggested to provide a halogen lamp with a burner surrounded by an outer envelope for an incandescent electric lamp. The appearance of this lamp is identical to known incandescent lamps, but the lamp is more power efficient as it uses the well-known technology of a 12 V halogen lamp.

  • Patent number: 7005800
    Abstract: An incandescent electric lamp includes a bulb, current-conductor wires, a filament having turns arranged in spiraling fashion around an axis of revolution, one end of the filament being connected to a conductor wire, a metal support connected to the other conductor wire and to the other end of the filament, and a metal bracket which is in electrical contact with one of the ends or one of the turns of the filament and which comprises a portion parallel to the axis of revolution of the filament and situated below the filament when the lamp is in its normal operating position. The metal bracket is, for example, at the potential of the end. At the end of lamp life, the filament sags and comes into contact with the metal bracket, thus causing a short-circuit and a breaking of the filament, which prevents an explosion of the lamp.
