Sine wave light-adjusting apparatus for lamp, has negative semi-period flywheel unit, connected with energy-storing unit and lighting unit, which is controlled by microprocessor to conduct during negative semi-period of sine wave voltage

摘要

A positive semi-period flywheel unit is connected with an energy-storing unit and a lighting unit. A microprocessor controls the flywheel unit to conduct during the positive semi-period of a sine wave voltage. A negative semi-period flywheel unit, connected with the energy-storing unit and lighting unit, is controlled by the microprocessor to conduct during the negative semi-period of the sine wave voltage.
