Abstract

A universal digital dimmer is revealed. The universal digital dimmer includes an electromagnetic radiation control circuit, a zero level detector, a leading / trailing edge automatic detector, an encoded signal generator, a no-load detection circuit, a power supply circuit, a dual-core or multi-core microcontroller, a state indicator and an output controller. The dimmer has a leading edge control mode and a trailing edge control mode. The dimmer detects and gets suitable waveform by switching between the leading edge control mode and the trailing edge control mode. Moreover, detection and automatic dimming control are performed independently by the dual-core or multi-core microcontroller. One dual-core or multi-core central processing unit (CPU) of the dual-core or multi-core microcontroller is used for detection operation while the other / another dual-core or multi-core CPU thereof is used for control operation. Thus 0ˆ¼100% dimming range of the load is achieved. The dimmer can work with different loads and the brightness stability is improved.

Description

technical field [0001] The invention relates to the technical field of dimmers for lamps, in particular to a digital universal dimmer. Background technique [0002] Phase dimmers are generally used in series with the load. Load characteristics affect the characteristics of phase dimmer operation. Traditional technology must decide which dimmer to use depending on whether the load is inductive, capacitive or resistive, so as to exert the best dimming effect. At present, due to the trend of LED energy-saving and environmental protection applications in lighting, traditional phase dimmers are used in LED lighting, which cannot achieve the best LED dimming effect. The reasons for the impact are as follows: For example, ①The LED brightness change corresponding to the input dimming range; ②The minimum load limit of the dimmer dimming; ③Because the LED must be driven by the servo drive circuit, the input capacitance of the drive circuit, current charge and discharge Noise interf...
