Abstract:
An electric incandescent lamp comprising:a shaped glass plate (1) which is connected in a gastight manner to current conductors (2) and to a metal tube (3) which extend through said plate;an incandescent body (4) occupying a predetermined position relative to the shaped plate (1) and connected to the current conductors (2);a glass bulb (5) around the incandescent body (4), connected in a gastight manner to the shaped plate (1) by means of enamel (6);a filling gas having a pressure of at least 1 bar inside the bulb (5),said metal tube (3) having a gastight seal (30) outside the bulb (5),characterized in that the shaped plate (1) is a sintered body made of a first glass and the bulb (5) is made of a second glass, the first glass and the second glass have coefficients of linear thermal expansion which are substantially equal at temperatures below the strain point of the glasses.
