<P>PROBLEM TO BE SOLVED: To provide a plasma lamp system which can be applied most suitably to an optical system requiring a point light source, and in which illumination efficiency can be maximized by making the point light source characteristics and a light spectrum characteristics improved, and provide a bulb used for it. <P>SOLUTION: This is the bulb of the plasma lamp system in which metal halide and mercury as main light-emitting materials are filled together, and the actuation pressure of the metal halide has a range of 0.1-10 atmospheric pressure, and the actuation pressure of the mercury has a range of 30-150 atmospheric pressure. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
