The cathode comprises a focusing device, an incandescent wire and a ceramic carrier, which ceramic carrier supports the focusing device and the incandescent wire in the housing.
Do not spray on a naked flame or any incandescent material.
The invention relates to a lamp comprising a lamp vessel (101), an incandescent body (102) arranged in the lamp vessel and current supply conductors (103) connected to the incandescent body.
The aim of the invention is to provide an incandescent body or a burner for an incandescent body which, independently of the above-mentioned fixing material, has increased durability in terms of resistance to impacts.
The proposed control circuit for an incandescent element serves to regulate the electrical heat energy of an incandescent element used in particular for auxiliary heating systems in vehicles.
The first filament is preferably used as a main beam filament and the second filament is used to generate a daylight driving beam.
The impermeable filling material (20) ensures reliable thermal conduction to the glow tube (5), without it being necessary to compress the filling material (20) by peening the glow tube (5).
The filaments (21, 22) are designed in such a way that the second filament (22) generates a lower luminance than the first filament (21).
The heating body (2) also comprises a ceramic heating element (15), which is placed inside the glow tube (6) and which serves to heat the glow tube (6).
The invention further relates to a production method for such a filament (22) and to electric lamps, preferably halogen lamps, having at least one such filament (22).
Method and apparatus for infrasonically intensifying a glow bed (13), supported by a grate (12).
In order to improve the service life of the glowing body (4), the sieve element (6) in the interior (3) of the connection piece is at least partially spaced apart from an inner wall (7) of the connection piece (1) facing the sieve element (6).
The inventive devices treats said material during the movement of the endless material and in the extension direction thereof and can be used for heating or annealing the endless material or for cleaning the surface thereof.
The distance between the luminescent element (6’) and the bulb (1) is less than 18 mm.
The surface igniting element (1) is supplied with combustion air during the operation of the vaporising burner.
The glow tube (6) guarantees a thermal and mechanical protection for the ceramic heating element (15).
An oxygen ion containing plasma is generated using a hot filament ion source.
Said luminescent element is provided with a metal carbide whose melting point lies above that of tungsten.
The small particles are specifically directed into a coiled ignition tube (25) located completely within the furnace (27).
