<P>PROBLEM TO BE SOLVED: To provide an illumination device capable of superbly improving the way how the skin looks. <P>SOLUTION: An illuminating part consists of an LED element with a half-value width of 30 nm, a peak wavelength of 455 nm, and emitting blue-color light, a phosphor with a half-value width of 130 nm and a peak wavelength of 550 nm, and a phosphor with a half-value width of 95 nm and a peak wavelength of 640 nm. The illuminating part is so structured that, if an output value of the blue-color light with a peak wavelength of 455 nm is 100%, an output value of light with a wavelength of 500 nm is to be around 55%, an output value of light with a wavelength of 550 nm is to be around 70%, an output value of light with a wavelength of 600 nm is to be around 87%, and an output value of light with a wavelength of 640 nm is to be around 78%. The illuminating part is also so structured that an output value of light with a wavelength of 640 nm to an output value of light with a wavelength of 600 nm is to be around 90% that is within a range of 85 to 110% and an output value of light with a wavelength of 640 nm to an output value of light with a wavelength of 550 nm is to be around 111% that is within a range of 95 to 135%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
