<P>PROBLEM TO BE SOLVED: To provide a multi-point light source unit in which at least only a phosphor or phosphor unit with short lifetime is replaceable to be it economical, and color rendering effect is improved without arranging a diffusion plate or the like, and emitting color is easily changed with a simple drive circuit. <P>SOLUTION: The light emitting elements 3 all having same emitting wavelength are used, and phosphors 4 of different kinds are used, thereby, each light emitting element 3 irradiates an illumination light having different emitting wavelength from each other to the outside. And at least the phosphor 4 is detachably installed on a base plate 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
