Abstract
A dimmer panel for controlling the intensity of a plurality of electric light sources includes a plurality of dimming circuits. Each dimming circuit has a control circuit, a heat producing controllably conductive power switch such as a triac, and a heat producing coil such as a choke. The power switches and coils are arranged on a corrugated heat sink to minimize component temperatures in the dimming control circuit and of the power switches. The heat producing coils are remotely located from the control circuit and the power switches, so that the heat generated by the coils does not increase the temperature of the components in the control circuit or of the power switches.
