Abstract
The invention is related to a light modulator using after-edge phase controllation consists of a light modulating controllor, an electronic after-edge phase controllor, an active switch, an overload protective circuit and a sealed out casing. The after-edge phase controlled light modulator using MOSFET or IGBT as active switch is also called MOS or IGBT light modulator. MOS-1, MOS-2 and MOS-3 modes are suited to be used for electric network in 220-277 V and 100-277 V. Said light modulator can do modulating for not only filament lamp but also electric energy-conserving lamp, electric ballast fluorescent lamp and electric radio lamp with capacitive impedance, it is a new and high technology product to replace silicon controlled light modulator.
