DEVICE AND METHOD FOR PRODUCING OUTPUT LIGHT HAVING A WAVELENGTH SPECTRUM IN THE INFRARED WAVELENGTH RANGE AND THE VISIBLE WAVELENGTH RANGE

摘要

PROBLEM TO BE SOLVED: To provide a device for producing output light in which the wavelength characteristics of the output light can be adjusted.;SOLUTION: The device of this invention comprises: a housing; a first light source which is coupled to the housing so as to function, and configured so as to generate first light having a peak wavelength in the infrared wavelength range, the first light being a component of output light; and a second light source which is coupled to said housing so as to function, and configured so as to generate second light having a peak wavelength in the visible wavelength range, wherein the light source contains a fluorescent material having a wavelength-converting property to convert at least some of original light generated by the second light source to produce the second light, the second light also being a component of the output light such that the output light has a wavelength spectrum in the infrared wavelength range and the visible wavelength range.;COPYRIGHT: (C)2007,JPO&INPIT
