    摘要： Disclosed is a lighting system capable of preventing damage to an outer-tube resulting from an outer-tube discharge that often occurs at the end of useful life of a lamp. The lighting system includes: a metal halide lamp having an arc tube housed within an outer tube; and a lamp .lighting device for operating the metal halide lamp. The lamp lighting device includes: a power supply unit operable to supply an electric power to the metal halide lamp; a detecting unit operable to detect an electrical property of the metal halide lamp; a judging unit operable to judge, based on the detected electrical property, whether a currently occurring discharge is an outer-tube discharge; and an instructing unit operable to instruct the power supply unit to suspend or reduce the electric power supply to the metal halide lamp upon a judgment that the currently occurring discharge is an outer-tube discharge. The detection unit detects a lamp voltage. The judging unit judges that the currently occurring discharge is an outer-tube discharge if the detected lamp voltage differs from a lamp voltage under normal operation.

    摘要： The present invention aims at providing a metal halide lamp that (i) prevents a decline in the lumen maintenance and a deterioration of quality in appearance due to the coloring of a casing tube surrounding the arc tube, and at the same time (ii) achieves high luminous efficiency. A metal halide lamp (1) has a pair of electrodes (20a&b) placed in an arc tube (3) made of translucent ceramic, and a sodium halide is enclosed therein. The metal halide lamp (1) satisfies L/D 4, where L (mm) is the length of the space between the electrodes (20a&b) and D (mm) is the internal diameter of the arc tube (3). The metal halide lamp (1) has a casing tube (2) surrounding the arc tube (3), at least around a portion between the electrodes (20a&b). Here, R/r 3.0 is satisfied, where R is the internal diameter of the casing tube (2) and r is the external diameter of the arc tube (3), within a region positionally corresponding to, in a radial direction of the arc tube, the space between the electrodes (20a&b), on a cross-sectional surface where an outer circumference of the arc tube (3) comes closest to the internal circumference of the casing tube (2).
