METAL HALIDE LAMP

摘要

A metal halide lamp comprising a discharge vessel (3) enclosing a discharge space (11 ) of volume V(cm3) and containing an ionizable gas filling comprising Hg in a quantity of mass m(g) and at least a metal halide, wherein in said discharge space (11) two electrodes (4, 5) are arranged whose tips (4b, 5b) have a mutual interspacing EA so as to define a discharge path between them, the discharge space (11 ) having a length L(mm) measured along the discharge path and a largest diameter D(mm) square thereto, wherein the ratio X=LVD satisfies the relation 0.7
