Abstract

The invention discloses a digital universal light modulator which integrates an electromagnetic radiation suppression circuit, a rectifying circuit, a switch circuit, a low-power-consumption current amplification circuit and acceleration loop, a power supply circuit, a single-core or multiple-core microcontroller, a zero potential detecting circuit, a front/rear shifting switch, an upper/lower regulation ON/OFF digital coding incrementer. The digital universal light modulator can change dimming/speed-regulation into front shifting or rear shifting waveforms according to different loads so as to achieve the purpose that any load is accessible, and the loads include loads of a halogen lamp, an electronic transformer, a CFL lamp tube stabilizer, a front shifting LED lamp, a rear shifting LED lamp, a fan speed regulator and the like different in capacitive character, inductive character and resistive character.

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...
