摘要:
The present invention relates to a metal halide lamp substantially containing no mercury, a metal halide lamp lighting device using the same and an automotive headlamp apparatus using the same. And object of the invention is to provide such products in which a rapid rising of luminous flux is achieved. A metal halide lamp (MHL) according to the present invention has: a discharge vessel having an inner volume of C (cc) and having a pair of electrodes (2), (2) sealed in a hermetic vessel (1a) at opposite ends of a discharge space (1a) in the hermetic vessel (1a) at a distance of 5 mm or less; and a discharge medium containing xenon gas at 3 atmospheres or higher, a halide of sodium Na, and at least one of halides of scandium Sc and rare earth metals, the melting point of the halides being T (K), in which a lamp power in a stable state is 50 W or lower, and the formula (1) is satisfied: (H/C)×[R/(T/500)6]

A metal halide lamp comprises a discharge container including a discharge space and a pair of sealing sections. A discharge medium containing a metal halide and a rare gas and essentially free from mercury is sealed in the discharge container. A pair of electrodes are arranged to face each other within the discharge space, and the side edge portions on the side of the proximal end portion of these electrodes are held by the sealing sections. The amount of water contained in the metal halide, i.e., the light-emitting material, included in the metal halide lamp essentially free from mercury, i.e., Hg-less metal halide lamp, is controlled to 50 ppm or less.
