PROBLEM TO BE SOLVED: To provide a low output (12W) or high output (20W) electrodeless discharge lamp capable of obtaining desired color development, a bulb color or a daylight color to be concrete, by correcting a luminescent color disturbed due to the influence of the plasma generated in a vessel, when driving the lamp at a high frequency (480 (±20)kHz). SOLUTION: When a low output bulb color is developed, the weight ratios of R,G,B phosphors are determined as 65.5-76.9:26.5-31.1:0-1.0 in this order respectively. When a low output daylight color is developed, they are determined as 34.13-40.05:29.86-35.06:28.01-32.89 in this order. When a high output bulb color is developed, they are determined as 66.4-78.0:25.6-30.0:0-1.0 in this order. When a high output daylight color is developed, they are determined as 35.69-41.89:30.51-35.81:25.81-30.29 in this order. COPYRIGHT: (C)2005,JPO&NCIPI
