Lighting control system with corrugated heat sink
First Claim
1. A dimming panel for controlling the intensity of a plurality of electrical light sources, said dimming panel comprising a thermally conductive support plate having a plurality of heat-generating dimming circuits disposed thereon, said support plate being a continuous serpentine sheet of material having a selected substantially uniform thickness and being shaped to form a plurality of first flats and second flats, said first flats and said second flats being substantially parallel to one another and being joined by portions of said continuous sheet which define wall portions disposed at an angle to said first and second flats, said first and second flats and said wall portions defining open channels between opposing wall portions.

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.
