摘要： A light-dimming device (10) of an aspect includes: first and second terminals (1, 2) a switch (3) connected between the first and second terminals (1, 2); an adjuster (6) configured to adjust a conduction angle of the switch (3); a controller (4) configured to control the switch (3); and a power supply module (5) connected between first and second terminals (1, 2) and configured to supply power to the controller (4). The controller (4) is configured to, within each half cycle of an AC voltage, keep the switch (3) off until a prescribed period of time (T1) elapses from zero-cross of the AC voltage, turn on the switch (3) when the prescribed period of time (T1) elapses, and turn off the switch (3) when a period of time (PW) corresponding to the conduction angle adjusted by the adjuster (6) elapses from turning on the switch (3).
