Abstract

A light source module for macro photography is disclosed. The light source module is for connecting to a lens of an image capturing apparatus and bearing against a plane surface to capture the image of the plane surface. The light source module includes a barrel, a contact unit and a lighting unit. The barrel has a rear portion for connecting to the lens and a front portion opposite to the rear portion. The contact unit is arranged on an end face of the front portion. The contact unit has a plurality of contact pads arranged at intervals on the end face for contacting with the plane surface. The lighting unit is arranged on the inner surface of the barrel.
