[0003]

In the above-mentioned conventional example, the size of the body is three modules, that is, the size of a series module or the size of a double module, because the phase control triac generates heat. It had to be large. Also, even if the module is manufactured with the above-mentioned module dimensions, the size of the dimensions is limited in order to correspond to the switch box, and since it is mounted on the switch box, there is a limit on the heat dissipation capacity. There was a problem that the whole body became hot.

Further, since the operation section and the dimming section are provided integrally and the size of the body is restricted as described above, the load control capacity is limited. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to separate a dimmer unit from a dimmer unit by separating an operation unit that requires wall mounting from the dimmer unit. It is an object of the present invention to provide an incandescent light dimmer which is free from dimensional restrictions, enables higher load control capacity by improving heat radiation efficiency, and enables a downsized operation unit which requires wall mounting.
