Abstract

A light source assembly and a projection device are provided, wherein the light source assembly (10) comprises a light emitting assembly (101) which emits a first laser beam (S1) and a second laser beam (S2), the positions of the first laser beam (S1) and the second laser beam (S2) which are incident to a converging mirror group (105) are distributed on two sides of the optical axis of the converging mirror group (105) and are not symmetrical with respect to the optical axis (h) of the converging mirror group (105), so that the first laser beam (S1) and the second laser beam (S2) can excite a fluorescence area (1031) to generate first fluorescence (E1) and second fluorescence (E2) respectively, and the first fluorescence (E1) and the second fluorescence (E2) are reflected by a fluorescence wheel (103) and then incident to a first light combining part (1022 a) and a second light combining part (1022 b) respectively; and the first laser beam (S1) and the second laser beam (S2) can be reflected by the reflecting area (1032) of the fluorescence wheel (103) and are incident to the first light-combining part (1022 a) and the second light-combining part (1022 b), so that the combined light output of the laser and the fluorescence is realized. The light source component not only has a compact optical frame, but also can realize the output of higher luminous power.
