PURPOSE: An LED light source module is provided to precisely detect image information of an object by supplementing a red light component through a sub light source. CONSTITUTION: An LED light source module includes a module plate, a printed circuit board(110), a white light source part(120), and a red light source part(130). The printed circuit board is mounted on the module plate. The white light source part is arranged on the printed circuit board, and has a plurality of LEDs(121), an optical pipe(122), and an optical pipe receiving part(123). The LEDs emit a white light. The white light of the LED is incident inside the optical pipe. The optical pipe receiving part receives the optical pipe. The red light source part is arranged on the printed circuit board in order to be separated from the white light source part.
