  • Halogen Incandescent Lamp Having a Carbide-Containing Luminous Element
    Publication number: 20100156289
    Abstract: The invention relates to an incandescent lamp having a carbide-containing luminous element and current supplies holding the luminous element. A luminous element is introduced into a bulb together with a filling in a vacuum-tight manner, the luminous element having a metal carbide the melting point of which is preferably above that of tungsten, and the luminous element being helical. The luminous element has a core wire and a wrapped filament and is constituted of various materials and contains a metal carbide.

  • Reflector Lamp
    Publication number: 20090051287
    Abstract: A reflector lamp, in particular a halogen reflector lamp, has a light-transmitting lamp vessel, in which at least one luminous member is accommodated, at least one vessel section of the lamp vessel being provided with a reflective coating. According to the invention, the reflective coating has an interference filter, which is substantially impervious to light in the visible wavelength range and has defined transmission and reflection properties for light in the infrared wavelength range.
