    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.

    摘要: A metal halide discharge lamp with which essentially permits disusing mercury is provided. The metal halide discharge lamp comprises a refractory and transparent hermetic vessel, a pair of electrodes fixed to the hermetic vessel, and a discharge medium sealed in the hermetic vessel and containing a first halide, a second halide, and a rare gas. The first halide is a halide of metal which achieves a desired light emission. The second halide has a relatively high vapor pressure, being at least one halide of metal which is unlikely to emit a visible light compared with the metal of the first halide and acts as a buffer gas.
