    Abstract: PROBLEM TO BE SOLVED: To generate light provided with a smooth spectral distribution in a visible light range so as to improve a color rendering property index by using a sulfur element, a selenium element, or a compound consisting of these elements as a filler of a lamp covered body, impressing electromagnetic radiation to a bulb so as to turn the filler into a plasma condition, and generating light by means of molecular radiation. SOLUTION: A lamp device 2, which is an electrodes lamp, is driven by means of microwave energy, and a filler inside the electrodless bulb (covered body) 3 contains a sulfur element, a selenium element, or one compound consisting of these elements. When the filler inside the non-electrode bulb 3 is excited by means of microwave energy so as to be turned into a plasma condition, light is generated by means of the filler so as to be taken out to the outside of a cavity via a mesh 5. In this way, light radiation dependent on molecular radiation inside a visible light area can be carried out and spectral luminous efficiency can be improved, while a small size high power light source emitting visible light can be accomplished.
