<P>PROBLEM TO BE SOLVED: To suppress manufacturing costs of an entire lighting system, while downsizing the entire lighting system. <P>SOLUTION: A lighting system 100 includes: a movable module 20 having a light-emitting element light source 1, a circuit board 2, a light guide lens 4, and a joint member 5; and a lighting system housing 6 for storing the movable module 20. The surface of the light guide lens 4 is constructed with a spherical surface 4a. The surface of the joint member 5 is constructed with a spherical surface 5a which has a smaller radius than the spherical surface 4a of the light guide lens 4, and is coaxial with the spherical surface 4a of the light guide lens 4. A hole 6a engaged with the spherical surface 4a of the light guide lens 4 is formed in the lighting system housing 6. A suspension member 9 contacted with the spherical surface 5a of the joint member 5, with the spherical surface 4a of the light guide lens 4 engaged with the hole 6a of the lighting system housing 6, is connected to the lighting system housing 6. The movable module 20 can be rotated around a central point C of the spherical surface 4a of the light guide lens 4 and the spherical surface 5a of the joint member 5, with respect to the lighting system housing 6. <P>COPYRIGHT: (C)2011,JPO&INPIT |
