<P>PROBLEM TO BE SOLVED: To improve performance of a lighting system through enhancement of coupling stability between a radiator and a cover part. <P>SOLUTION: The lighting system is provided with a radiator having a surface, a guide part with a housing part, and a first protruded part arranged on an outer periphery of the surface, a light-emitting module part arranged on a surface of the radiator, and a cover part coupled to the radiator, having a locking projection coupled to the housing part of the radiator and a groove coupled to the first protruded part of the radiator. Separation between the radiator and the cover part is restricted due to coupling between the locking projection and the housing part, and therefore, rotation of the cover part is restricted due to coupling between the first protruded part and the groove of the cover part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
