DC arc lamp

摘要

The lamp filling consists of an ignition gas, e.g. argon, mercury and a halogen. To this is added a proportion of zinc to amplify the red component whilst reducing the color separation effect. The lamp bulb is of an asymmetrical shape relative to the plane (1) vertical to the longitudinal axis (2) in that the inner wall (3) enclosing the anode (4) is further from it than from the cathode (5),(radius of curvature ((8).smaller than (9)). This increases the temperature homogeneity
