Beschreibung
Zusammenfassung:	The invention provides a light source module and a projecting device. The light source module comprises a light source and a lens, wherein the light source is used for generating a light beam, and the lens is arranged on one side of the light source and used for converging the light beam. An incident plane of the lens is a spherical surface or a first aspheric curved surface, an emergent plane of the lens comprises two second aspheric curved surfaces configured symmetrically about an optical axis of the lens, and an optical axis of each second aspheric curved surface deviates from that of the lens. Each second aspheric curved surface comprises a first portion and a second portion, wherein the second portion is close to the optical axis of the lens relative to the first portion, and the curvature radius of the second portion is less than that of the first portion. An absolute value of the curvature radius of the incident plane is more than that of the curvature radius of each second aspheric curved surface.
