Abstract:
An incandescent lamp having a carbide containing luminous element, uses a wire for the luminous element that is coated on the outside with at least two different high melting metal compounds from at least one of the groups of carbides, borides and nitrides. The luminous element reaches a temperature of at least 3000° K during operation.
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.
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, 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.
Abstract:
An electric lamp with a fuse seal, which seals off the lamp bulb, a metal seal with power supply wires and feed lines being provided in the fuse seal, and the metal seal with power supply wires and feed lines being provided with a structure, which has been produced by a laser.
