<P>PROBLEM TO BE SOLVED: To provide a lighting system in which a heat radiation property of a heat generated by a light emitting element is improved and light from the light emitting element is irradiated radially, and the light utilization ratio from the light emitting element is improved. <P>SOLUTION: In the lighting system in which a plurality of radiation fins 2b1 to 2b8 to radiate a heat generated by the light emitting element 4 are arranged radially, open mouths 2b1c to 2b8c through which a light from the light emitting element 4 passes are formed between neighboring fins 2b1 to 2b8, and reflecting faces 2b1a, 2b1b, 2b2a, 2b2b, 2b3a, 2b3b, 2b4a, 2b4b, 2b5a, 2b5b, 2b6a, 2b6b, 2b7a, 2b7b, 2b8a, 2b8b are formed on surfaces of radiation fins 2b1 to 2b8. <P>COPYRIGHT: (C)2007,JPO&INPIT |
