Document Type and Number:
WIPO Patent Application WO/2020/052297
Kind Code:
A1
Abstract:
Disclosed by the present invention is a light regulation and speed regulation circuit, comprising a main trigger circuit connected in series between a live end and a neutral end; the main trigger circuit comprises an adjustable resistance network; further comprised is a compensation circuit connected in parallel with the adjustable resistance network, the compensation circuit comprising a switch execution element, and the compensation circuit providing current compensation to the adjustable resistance network within a period of time after the power supply switch is closed so as to meet the start-up current of a load and cause the switch execution element in the compensation circuit to be continuously switched on during said period of time; therefore, the brightness of the load or the speed of the load may be adjusted by means of the adjustable resistance network and the switch execution element in the compensation circuit. The present invention causes a lamp to work in a state of or close to the minimum brightness that may be self-maintained by the lamp after the light regulation switch is closed, or causes a fan to be in a state of the minimum operating current after a speed regulator switch is closed so as to solve the problem of dead stroke (invalid stroke) upon startup as well as the problem wherein use is inconvenient.
