Abstract
The circuit comprises a bidirectionally conductive switch GL, T1, including at least one FET, connected in series with a lamp Z across an A.C. supply, a control circuit CO causing the switch to turn on at zero crossings for an adjustable portion of each A.C. half cycle, and means R,C giving rise to a gradual turn off of the switch in each half cycle. The switch may comprise a bridge rectifier GL with a diagonally connected FET T1, two series-connected FET's (T1), (T2) with respective parallel-connected inverse diodes (D1), (D2), (Fig 4), or two parallel-connected FET's (T3), (T4) with respective series-connected diodes (D3), (D4), (Fig 5). <IMAGE>
