Title:
LIGHT SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/027717
Kind Code:
A1
Abstract:
The light source device (1) according to the present invention is provided with: a long-wavelength light source (23) emitting long-wavelength light (Lr) having a peak wavelength in a red wavelength band; a single broadband light source (22) emitting broadband light (Lg) which includes a green wavelength band of 500-580 nm, has a peak wavelength of 580 nm or less, and has, at a long-wavelength side thereof, a wavelength band overlapping a wavelength band at a short-wavelength side of the long-wavelength light (Lr); and a multiplexing unit (32) for multiplexing a wavelength band having wavelengths longer than a predetermined wavelength of the long-wavelength light (Lr) and a wavelength band having wavelengths less than or equal to a predetermined wavelength of the broadband light (Lg), wherein the predetermined wavelength is between the peak wavelength of the long-wavelength light (Lr) and the peak wavelength of the broadband light (Lg), and is also a wavelength in which the intensity of the long-wavelength light (Lr) is 10% or more of the peak intensity thereof, and the intensity of the broadband light (Lg) is 10% or more of the peak intensity thereof.
