Abstract

A mercury-free high-pressure discharge lamp includes a light-transmissive airtight envelope enclosing therein a discharge space, a pair of electrodes sealed inside the light-transmissive airtight envelope and facing the discharge space, and an ionization medium substantially excluded mercury therefrom, which is filled in the light-transmissive airtight envelope, wherein the ionization medium contains, a principal metal halide including thulium (Tm) as primary constituent thereof and capable of emitting light mainly at a visible range, an accessory metal halide including zinc (Zn) as primary constituent thereof and capable of fixing lamp voltage, and rare gas.
