| titleOfInvention | Lighting system |
| abstract | 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. |
