Document Type and Number:
WIPO Patent Application WO/2020/077953
Kind Code:
A1
Abstract:
A dimming signal processing circuit having multiple functions comprises a dimming signal input terminal and a dimming signal output terminal, and further comprises: an input signal processing circuit (10), a modulation circuit (20), an isolation circuit (40) and an output shaping circuit (50) connected in cascade to the dimming signal input terminal; and an oscillation signal output circuit (30) connected to the modulation circuit (20), wherein the output shaping circuit (50) comprises a plurality of signal output circuits separately connected to the dimming signal output terminal. The dimming signal processing circuit having multiple functions reduces costs while meeting more use requirements.
