<P>PROBLEM TO BE SOLVED: To provide a lighting system capable of cooling an LED and a substrate with the LED mounted by rotating a fan without consuming power. <P>SOLUTION: A radiator 2 is fixed to a substrate-mounting plate 4 with a substrate 7 attached with an LED 8 mounted. Inside an inner space 11 of the radiator 2, a thermo-sensitivity actuating mechanism part 32 operated in accordance with temperature change inside the inner space 11, a fan-driving mechanism part 33 operated by the thermo-sensitivity actuating mechanism part 32, and a fan 34 rotationally driven by the fan-driving mechanism part 33 are housed. The substrate 7 with the LED 8 mounted and the LED 8 can be cooled by air flow generated by the fan 34 rotationally driven by the fan-driving mechanism part 33. Therefore, a motor is not necessary for rotating the fan 34, no power is consumed for rotating the motor, and thus, energy saving can be achieved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
