    • This invention provides a small metal halide lamp which has a power input of 100 W or less, provided with: an arc tube having a pair of electrodes spaced apart from each other and containing a rare gas, mercury, sodium halide and scandium halide therein; and an envelope for housing the arc tube. The mixing ratio of sodium halide to scandium halide based on weight is 3:1 to 10:1, and the total content of the sodium halide and the scandium halide is 10 to 40 mg per unit volume (cc) of the arc tube. At least one phospor selected from the group consisting of a manganese-activated magnesium fluorogermanate phosphor and a cerium-activated yttrium aluminate phosphor is applied to the inner surface of the envelope. In addition, a green-emitting phosphor is preferably coated on the inner surface of the envelope.
    • 本发明提供一种功率输入为100W以下的小型金属卤化物灯,其具有:具有一对彼此间隔开的电极的电弧管,其中含有稀有气体,汞,卤化钠和钪卤化物; 以及用于容纳电弧管的信封。 卤化钠与卤化钪的混合比例为3:1至10:1,卤化钠和卤化钪的总含量为每单位体积(cc)的电弧管为10〜40mg。 将至少一种选自锰活化的氟氟代钼酸荧光体和铈活化的铝酸钇磷光体的磷选择施加到外壳的内表面。 此外,绿色发光荧光体优选涂布在外壳的内表面上。
