    Abstract: A light source assembly, an imaging device and an imaging method are provided. The light source assembly comprises a light source component emitting a first light beam; a fluorescent excitation device receiving the first light beam and exciting a second light beam; a coupling device receiving an incident light beam and coupling the incident light beam into a third light beam, wherein the incident light beam includes the second light beam or includes the second light beam and the first light beam. The imaging device comprises the above-mentioned light source assembly and a projection system receiving the third light beam. The imaging method comprises: generating a first light beam; exciting a second light beam by using the first light beam; coupling the second light beam into a third light beam or coupling the second light beam and the first light beam into a third light beam; and imaging with the third light beam. The light source assembly, imaging device and imaging method can represent more plentiful colors and have wider color gamut.
