<P>PROBLEM TO BE SOLVED: To provide a luminous flux control member can controll an advancing direction of an emitted light by matching to an irradiated surface and reducing dazzlingness when looking squarely. <P>SOLUTION: The luminous flux control member 100 includes an incident part 110 formed on a central part of the luminous flux control member 100 and making light emitted from a light-emitting element 200 incident, a plate-shaped light guide part 120 formed between the central part and an outer peripheral part of the luminous flux control member 100 and guiding light incident from the incident part 110 to the outer peripheral part of the luminous flux control member 100, and an emitting part 130 formed on the outer peripheral part of the luminous flux control member 100 and emitting light guided with the light guide part 120 to the outside. <P>COPYRIGHT: (C)2013,JPO&INPIT |
