摘要: A metal halide lamp in which an arc tube is housed within a bulb having base at one end thereof. The includes main tube, two thin tubes that extend from each of the and pair electrode inductors. are made translucent polycrystalline alumina constitute discharge vessel space therein. Lamp power under dimming conditions set range defined by maximum Wmax [W] minimum Wmin [W], with surface area S [cm2] inner satisfying Wmax/60 ≤ Wmin/20.
