Patent ID: 7821569

Claim:
A converter lens attached to an object side of a non-interchangeable lens of a compact digital camera, comprising: a mounting seat being a disk with a hollow portion and having a plurality of holes thereon; a lens embedded in the hollow portion of the mounting seat; a printed circuit board (PCB) with a centered hollow corresponding to the lens, parallelly mounted on the mounting seat, having a plurality of light emitting diodes (LEDs) on one side of the PCB, and having a plurality of conductive pins on an another side of the PCB, wherein the conductive pins pass through the holes of the mounting seat; an adapter ring accommodating the mounting seat and the PCB; a light diffuser made of translucent plastic, composed of a hollow cone and a mounting ring at a small end thereof, a gap being remained between the mounting ring and the small end of the hollow cone, and the mounting ring being accommodated in the adapter ring to connect with the PCB, wherein the LEDs face the gap for emitting light through the hollow cone; a sleeve having a surrounding flange for leaning against the adapter ring, and passed through by the hollow cone, wherein the mounting seat, the PCB, the light diffuser and the sleeve are fixed together by one or more fastening elements; a barrel axially connected to the sleeve for entirely accommodating the hollow cone; and a base body removably connecting with the adapter ring, having a plurality of cavities for being inserted by the conductive pins, having a battery therein for supplying power to the PCB through the conductive pins, and having a switch thereon for switching on/off power from the battery to the PCB; thereby the base body is removably mounted on the camera.
