<P>PROBLEM TO BE SOLVED: To provide a dimmer capable of effectively radiating heat even if it is interconnected with each other. <P>SOLUTION: A plurality of interconnected dimmers 1 comprises cases 11, a plurality of circuit elements (i.e. a variable resistor 53, a triac 54 or the like) for organizing dimming circuits which light-control incandescent lamps housed in the cases 11, and radiating plates 62 for radiating heat generated on the circuit elements housed in the cases 11. The radiating plate 62 is provided with a first plate-shaped radiating piece 62a arranged parallel to the front face of the case 11, and a second radiating piece 62b and a third radiating piece 62c which are orthogonal to the interconnecting direction of the dimmer 1 at the first radiating piece 62a and respectively extend backward from both ends in the direction parallel to the front face of the case 11. <P>COPYRIGHT: (C)2009,JPO&INPIT |
