The present invention is aimed to design an improved lighting assembly for camera module of an endoscope. The camera module is received in a cylinder body, which is connected with the tail end of the tube of the endoscope. The character of this invention is to provide a secondary lighting apparatus between the cylinder body and the tube. The secondary lighting apparatus includes several LEDs being mounted inside annular-arrayed and covered by a transparent ring. The annular-arrayed LEDs can emit light through the transparent ring with 360 degrees lighting outwards that provides a perfect lighting effect for capturing the inner images of patients and will facilitate the judgement of users or doctors.
