Title: ELECTRIC INCANDESCENT LAMP
Abstract:
The electric incandescent lamp has a sintered glass plate (1) through which current conductors (2) and a metal tube (3) extend. An incandescent body (4) is connected to said current conductors (2) aligned with respect to the plate (1). A glass bulb (5) is present over the incandescent body (4), gastight secured to the plate (1) by means of enamel (6). A water getter (20) and a heavy gas at an elevated pressure are present inside the glass bulb (5). The lamp may consume a relatively high power and may be relatively small, but nevertheless has a relatively long life.
