Patent ID: 8594495

Claim:
A short-range photographic light source module for use in an image capture device, the image capture device comprising an imaging lens having a light axis, wherein the short-range photographic light source module is mounted at a position corresponding to the imaging lens and serves as a light source when the image capture device is capturing an image of a target object at a short distance, the short-range photographic light source module comprising: a sleeve tube, extending along the central axis and being engageable with the image capture device, wherein the sleeve tube comprises a rear end portion adapted to be arranged close to the imaging lens, a front end portion opposite to the rear end portion and remote from the image capture device, an interior side connecting the front end portion to the rear end portion, and a light shield portion close to the front end portion; a first illuminating unit, mounted on the interior side of the sleeve tube to emit light with a first central wavelength in a direction corresponding to the central axis; and a second illuminating unit, mounted on the interior side of the sleeve tube to emit light at an angle with respect to the central axis, wherein the light emitted from the second illuminating unit has a second central wavelength different from the first central wavelength; wherein the first illuminating unit comprises a plurality of first light emitting diode (LED) elements and the second illuminating unit includes a plurality of second LED elements; and wherein the first LED elements are mounted on a first ring belt and the second LED elements are mounted on a second ring belt separated from the first ring belt, and wherein the short-range photographic light source module further comprises an optical lens unit mounted between the ring belts and the rear end portion and having a symmetry axis extending along the light axis.
