Abstract
A light source system and a lighting apparatus comprising: a light-emitting module which emits first light along a first light path and second light along a second light path; a wavelength conversion device which received the first light to emit excited light with a different color from that of the first light; and a compensation device which guides the second light and adjusts a luminous intensity distribution of the second light so that the luminous intensity distribution of the second light exiting from the compensation device is substantially identical to that of the excited light. The second light exiting from the compensation device is combined with the excited light to form third light to be emitted from the light source system. The luminous intensity distributions of the first light and the second light in the third light are substantially the same, and illumination light spots have a uniform color.
