Embodiment Construction

[0039] A component for an electric lamp that increases the service life of a lamp cap will be described using a halogen lamp cap as a first example. However, these components can also be used for lamps that operate on different principles, such as ordinary incandescent lamps that do not use the halogen cycle, metal halide lamps, high intensity discharge tubes, mercury vapor lamps, and sodium vapor lamps. Common parts for these lights are in Figure 4 Illustrated with a virtual ordinary light in . In each of the mentioned lamps, the interior of the lamp envelope contains a gas and / or vapor mixture which is isolated from the surroundings of the lamp envelope. The electrodes or filaments are located inside the lamp envelope and are connected to the terminals by means for conducting the electric current which must pass through the lamp envelope. The components described here contribute to prolonging the sealing between the interior and exterior of the lamp envelope, especially i...

Abstract

A lamp comprising a lamp envelope of vitreous material having a pinched portion at at least one end to form a seal isolating the interior of the lamp envelope from the surrounding environment of the lamp envelope, which The lamp also includes means for conducting current to the interior of the lamp envelope, the means having a section embedded in one of the pinch portions of the lamp envelope and a section outside the lamp envelope. At least a portion of the embedded section of the device for conducting electrical current is at least partially surrounded by a composition comprising at least one of phosphorus and phosphoric acid in non-volatile form.

Description

technical field [0001] The invention relates to lamps comprising a lamp envelope of vitreous material having a pinched portion at at least one end to form a seal isolating the interior of the envelope from the surrounding environment of the envelope, The lamp also includes means for conducting electrical current inside the lamp envelope, the means having a section embedded in one of the pinch portions of the lamp envelope and a section outside the lamp envelope. [0002] The invention also relates to a method of manufacturing a lamp comprising: providing a lamp envelope of vitreous material which is open at at least one end; providing at least one means for conducting electric current; A device for conducting current is inserted through at least one open end, leaving a protruding section of the device protruding from the open end; clamping the open end to form a pinched portion of the lamp envelope; connecting the interior of the lamp envelope to the The environment around th...
