    • A light source apparatus (10) includes a red light emitting device (100, 130) to emit red light; a green light emitting device (110, 140) to emit green light; a blue light emitting device (120) to emit blue light, each of the red light emitting device, the green light emitting device, and the blue light emitting device disposed separately from any other. Among the red light emitting device, the green light emitting device and the blue light emitting device, at least two light emitting devices each includes a first light source (100, 110) and a second light source (130, 140), the first light source (100, 110) emitting light having a wavelength of a light of a primary color, and the second light source (130, 140) emitting light having a wavelength deviated from the wavelength of the light of the primary color.
    • 光源装置(10)包括发射红光的红光发射装置(100,130) 绿光发射装置(110,140),发射绿光; 用于发射蓝光的蓝光发射装置(120),所述红光发射装置,所述绿光发射装置和所述蓝光发射装置中的每一个被布置为彼此分离。 在红色发光装置,绿色发光装置和蓝色发光装置中,至少两个发光装置均包括第一光源(100,110)和第二光源(130,140),第一光源 源(100,110)发射具有原色光的波长的光,并且第二光源(130,140)发射具有偏离原色光的波长的波长的光。
