20130058072 | LIGHT-SOURCE DEVICE - Disclosed is a light-source device that allows for the color recognition and can prevent a UV (ultraviolet)-sensitive illuminated object from becoming exposed. A user can freely select the wavelength of said light-source device in accordance with the intended use. The light-source device is provided with a light-source unit comprising a combination of a plurality of light-emitting diode elements that emit different wavelengths of light; a control unit that controls the output of each of the various light-emitting diode elements in the light-source unit independently of each other; and a power supply unit that supplies power to the light-source unit and the control unit. The plurality of light-emitting diode elements include, at least, a blue light-emitting diode element. The blue light-emitting diode element emits a blue light with a wavelength of at least above 420 nm. | 03-07-2013 |
