ELECTRICITY LEAD-IN BODY FOR BULB AND METHOD FOR MANUFACTURING THE SAME

摘要

The object of the invention to devise an electrical insertion body for a tube lamp in which sealing bodies of an electrically conductive inorganic material component and a dielectric inorganic material component and upholding parts of the electrodes are attached securely to one another by sintering, and in which neither leaks nor falling out of the upholding parts of the electrodes occur. The object is achieved as claimed in the invention, in an electrical insertion body for a tube lamp in which an upholding part of the electrode is inserted into the center opening of a respective sealing body of a functional gradient material for a tube lamp, in that in the boundary areas between the sealing bodies and the upholding parts of the electrodes one diffusion area at a time is formed, in which the electrically conductive inorganic material component of the sealing body, the metallic component of the upholding part of the electrode and a diffusion accelerator are present diffused into one another, which at the sintering temperature accelerates diffusion of the electrically conductive inorganic material component of the sealing body and of the metallic component of the upholding part of the electrode and that in this way the upholding part of the electrode and the electrically conductive inorganic material component of the sealing body are joined to one another. <IMAGE>
