PROBLEM TO BE SOLVED: To provide an electrodeless discharge lamp lighting apparatus with high light emitting efficiency, superior starting ability, and little deterioration of luminous flux. SOLUTION: This electrodeless discharge lamp lighting apparatus 1, having a valve 2 made of a translucent material enclosing a discharge gas, an induction coil 3 disposed adjacent to the valve 2 and a high-frequency power supply 5 for feeding a high-frequency current to the induction coil 3, excites the discharge gas enclosed in the valve 2 to emit light by causing a high-frequency electromagnetic field to act on the discharge gas. The apparatus also has a device for generating a static magnetic field to disperse the discharge gas excited cause it to emit light. |
