Definitions
- the metal halide high-pressure discharge lamp according to the invention is operated at specific arc powers between 100 and 180 W per mm arc length. With the compact geometric dimensions of the lamp - very short electrode spacing (a few mm) and small vessel volume (a few tenths of a ml) - this corresponds to wall loads of 70-120 W per cm 2 wall area of the discharge vessel. By means of the filling components of the discharge vessel according to the invention, average luminances of 25-75 kcd per cm 2 of arc area are achieved, which can be focused on a light spot whose diameter is less than 10 mm with the aid of a reflector or other optical system.
- Dysprosium (Dy), hafnium (Hf), lithium (Li) and indium (In) are added to the filling of the lamp according to the invention, which consists of mercury, at least one noble gas and at least one halogen.
- the fill quantities in ⁇ mol per ml vessel volume are advantageously between 0.3 and 3 for Dy, Hf and Li and between 0.2 and 2 for In.
- Dysprosium ensures a high radiation flow in the visible range of the electromagnetic spectrum and additionally contributes to the continuity component.
- Hafnium also produces a multi-line spectrum and also reduces the tendency to devitrification by building a reinforced halogen jacket on the piston wall.
- the high vapor pressure of the hafnium halides also reduces the tendency to bulge bulbs and consequently increases the useful luminous flux during the lamp life.
