Abstract

The invention provides an AC LED light adjustment method which is characterized in that PWM signals are adopted to directly modulate the AC supply voltage for working of an AC LED, the AC voltage envelope wave form and the AC voltage peak value are kept constant, the AC voltage effective value is adjusted by PWM duty cycle, the light adjustment range of the AC LED is enlarged to be 1-100%, and the light adjustment is stable. The invention further provides an inductive light adjustment controller for realizing the AC LED light adjustment method. The adopted method or inductive light adjustment controller provided by the invention can be widely applied to AC LED lamps, light adjustment and inductive intelligent automatic light adjustment can be realized, the purpose of dynamic secondary energy conservation is achieved, and the energy conservation effect is obvious.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an ACLED dimming method and an induction dimming controller. Background technique [0002] At present, the dimmers on the market are divided into two methods: front-edge phase-cut dimming and trailing-edge phase-cut dimming. With the mature technology of ACLED, it is more and more widely used. Compared with low-voltage LEDs, high-voltage ACLEDs do not need to be driven, and the cost is relatively lower. In many places where lighting requirements are not very high, ACLEDs have very high advantages. [0003] The current dimmers are not compatible with ACLED lamps. Due to the high voltage required by ACLED, when the dimmer cuts the phase to a certain angle, the ACLED will go out, and the dimming range is narrow and flickering. If the ACLED adopts the segmented power supply mode, it will be more prominent, and it will go out when the dimmer is adjusted to half, and there is no dimming ef...
