摘要： A metal halide lamp comprises a light-transmitting discharge vessel having a discharge space portion, a sealed portion, and a pair of electrodes projecting into the discharge space. The discharge vessel is constructed and arranged to have a D/L ratio being in a range of about 0.25 to about 1.5 and a t/L ratio being in a range of about 0.16 to about 1.1, wherein L is an interspace of tips of the electrodes, D is a maximum inner diameter of the discharge vessel, and t is a maximum wall thickness of the discharge space portion. An ionizable filling contains a rare gas and a metal halide including at least sodium (Na) or scandium (Sc) and does not substantially include mercury (Hg). Each of conductive wires is connected electrically to the electrodes extending from the discharge vessel. The metal halide lamp may be used for a metal halide lamp apparatus or a vehicle lighting apparatus.
