Abstract:
Luminous body for an incandescent lamp and method for producing such a luminous body. A wire for a luminous body is used whose diameter increases from the outside in. The production method is based either on a deposition method or a metal-removal method.
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, said luminous element having a metal carbide the melting point of which is preferably above that of tungsten, and the luminous element being helical. The rise of the filament varies from the center towards the ends.
Abstract:
Disclosed is a halogen light bulb comprising a carbide-containing filament and lead-in wires which retain the filament. A filament is vacuum-tightly introduced into a bulb along with a filling. The filament is provided with a metal carbide whose melting point is greater than that of tungsten, the carbon concentration of the metal carbide being smaller than that corresponding to complete carburization, i.e. carburization resulting in the production of metal carbides in which the number of metal atoms and the number of carbon atoms are at an integer stoichiometric ratio relative to each other.
Abstract:
The invention relates to a light bulb (1), equipped with an illumination body (7), which is enclosed together with a filler (2) in a vacuum in a bulb (2). Said illumination body (7) comprises a metal carbide, whose melting point lies above that of tungsten. The bulb also contains carbon, hydrogen and fluorine, preferably in combination.
Abstract:
The invention relates to an incandescent lamp (1) which is provided with an illuminant (7) which is inserted in a bulb (2) together with a filling in a vacuum-tight manner, said illuminant (7) comprising a metal carbide that has a melting point above that of tungsten. The bulb also comprises a source and a sink for a material of which the illuminant is depleted during use.
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, said 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.
Abstract:
A light source comprising a heatable filament (1) or an electrode, wherein the filament (1) or the electrode is arranged in a lamp (2) or in a tube. In order to use the light source in a wide variety of manners even in rough conditions, the filament (1) or the electrode is provided at least partially with a mechanical stabilization system. The invention also relates to a method for mechanical stabilization of the filament (1) or electrode of a light source, wherein stabilization is produced by exposing the filament (1) or electrode to a short pulsed gas pressure increase, involving a rare gas, during heating or stabilization is formed by a coating or deposition (4).
Abstract:
Disclosed is an incandescent lamp that uses a carbon cycle and comprises a luminescent element which is inserted in a vacuum-tight manner in a bulb along with a filler. Said luminescent element is provided with a metal carbide whose melting point lies above that of tungsten. The distance between the luminescent element and the bulb is less than 18 mm. A first cycle for the carbon is created by using carbon and hydrogen as an additional filler while a second cycle for the metal is created by using halogen.
Abstract:
The invention relates to a halogen incandescent bulb comprising an illuminant having nitride. An overpressure fill using nitrogen is used simultaneously.
