  • Mercury short-arc lamp with niobium getter
    Patent number: 6369508
    Abstract: The invention proposes arranging a getter (7) made from niobium on the electrode rod (4) of a mercury short-arc lamp, the two following conditions being fulfilled: D>1.8·d and &agr;≧20°. In this case, D and d denote a diameter of the relevant electrode head (2) or the associated electrode rod (4), and &agr; denotes an angle which is defined by the longitudinal axis of the electrode and an imaginary connecting line between the end of the getter (7) averted from the electrode head, and a point on the perpendicular, running through the end of the electrode rod on the electrode head side, to the electrode longitudinal axis. The point mentioned corresponds to the projection of the maximum radius of the lateral surface of the electrode head onto this perpendicular. An improved maintenance of the lamp is thereby achieved.
