Beschreibung
Zusammenfassung:	An optical lens module includes a lens body and a transflective unit. The lens body has a central axis, and has an incident surface, a refractive surface and a side refractive surface. The refractive surface includes a refractive arc-surface and at least one auxiliary refractive surface on the side of the refractive arc-surface. The transflective unit covers the refractive surface. The light incident on the refractive surface is diverged away from the central axis and the diverged light on the transflective unit is partially through the transflective unit and partially reflected to travel out of the lens body through the side refractive surface. The light incident on the transflective unit is reflected to travel out of the lens body through the side refractive surface. The light incident on the side refractive surface is refracted out of the lens body through the side refractive surface.
