    • Metal halide lighting with good color during dimming may be obtained. An appropriate balance of commonly used metal halides (NaI, DyI3, CeI3, CaI2, TlI) is dosed in the lamp. No mercury is used. A higher than typical xenon fill pressure from 50 to 500 Kilopascals may be used to help control thermal properties and voltage. If necessary, modulation of the power at acoustic resonance frequencies may be used to straighten and center the arc. Efficient and pleasant white output is obtained. As the power is reduced, the chromaticity either (1) remains fairly constant or (2) drifts acceptably towards warm pinkish colors. Large factors of attenuation in output can be realized. The lumen output was reduced by at least a factor of twenty in one sample as the power was dimmed from 70 to 20 watts.
    • 可以获得在调光期间具有良好颜色的金属卤化物照明。 在灯中加入常用的金属卤化物(NaI,DyI 3,CeI 3,CaI 2,TlI)的适当平衡物。 不使用汞。 可以使用高于典型的50至500千帕斯卡的氙气填充压力来帮助控制热性能和电压。 如果需要,可以使用声共振频率下的功率调制来使电弧矫直和居中。 获得高效宜人的白色输出。 随着功率的降低,色度(1)保持相当恒定,或(2)可以接受温暖的粉红色。 可以实现输出衰减量大的因素。 当功率从70瓦变到20瓦时,一个样品中的流明输出减少了至少二十分之一。
