<P>PROBLEM TO BE SOLVED: To provide a light source unit and a lighting system, which irradiate light efficiently on an object, are easy to obtain desired light distribution, and suppress light leakage other than the purpose. <P>SOLUTION: The light source unit is equipped with: a light emitting element 52 disposed on an inner surface of a side wall 4; a reflective surface 31 which is opposed to the light emitting element 52 so that light emitted from the light emitting element 52 is irradiated parallel to the side wall 4, and is formed of a part of a curved surface which is opened in an irradiation direction; and a light shielding member 7 having one end positioned on an approximately straight line linking the light emitting element 52 and an end part of the reflective surface 31 in an irradiation direction, and the other end arranged so as to extend in the irradiation direction. <P>COPYRIGHT: (C)2011,JPO&INPIT |
