PROBLEM TO BE SOLVED: To provide a close-up lighting system that can be mounted easily in a photographic lens by necessary minimum miniaturization by enabling lighting for the time necessary for photographing by a light source enhancing emission efficiency and enabling illumination, without irregularities, from omnidirections to a close-up object. SOLUTION: In the accessory of a camera that can be mounted on the edge of the photographic lens, a cylindrical member 4 has a ring-like light source embedding a plurality of white color emission diodes 8 on the edge in the form of a ring, mounts a switch 5 for on-off operations for supplying current to the white color emission diodes 8, and has lens hood functions. In addition, the ring-like edge of the cylindrical member 4 is sealed with a ring-like optical beam transmissive plate 9 on the front of the buried white color emission diode 8. The optical beam transmissive plate 9 is molded into a Fresnel lens 9a, to uniformly irradiate the light source toward the object. COPYRIGHT: (C)2007,JPO&INPIT
