摘要：PROBLEM TO BE SOLVED: To prevent thermal effects such as deformations and fusion resulting from heat generated by a dimmer used for a luminaries, and to downsize the same. SOLUTION: An auxiliary heat radiating plate 14, having the nearly same plane shape as a case outer shape is, sandwiched between a fitting plate 13 used for sealing a dimmer board 2 in a case and an insulation plate 12, so that its one part touches a heat-radiating plate 10 integrally connected with a triak 8 to become particularly high temperature. Thereby, the generating heat of a dimmer board in the case of a dimmer is efficiently and uniformly transferred to the fitting plate, and the side face portion of the case via the auxiliary heat-radiating plate for preventing the local temperature rise of the case thermal effects such as deformations and fusion resulting from the heat of the case are suppressed. Through efficient heat conduction, the dimmer itself can be downsized and a load capacity can be improved.
