Description

technical field [0001] The invention relates to the field of dimmers, in particular to an intelligent switch dimming control circuit. Background technique [0002] For dimmers, the commonly used adjustment method is phase-cut adjustment. By adjusting the input voltage to output within a certain phase, different dimming requirements can be achieved. In the existing technical solutions for phase-cutting adjustment, research is often conducted on a certain type of phase-cutting method, such as independent leading-edge phase-cutting or trailing-edge phase-cutting, but a single type of phase-cutting circuit cannot meet the requirements. All the requirements of phase-cut adjustment, and the characteristics of leading-edge phase-cutting or trailing-edge phase-cutting, make it impossible for switching dimming circuits using them independently to meet all requirements. [0003] At the same time, the dimmers on the market are often targeted at a certain standard grid for matching re...

Problems solved by technology

As we all know, the voltage range and frequency of grid voltage in different countries and regions are different, but the existing dimmers have not considered this issue, that is, the existing products often use different types of dimmers for different grid voltages. dimmers, the use of existing dimmers is greatly limited

[0004] Furthermore, the intelligent control switches or sockets of dimmers are currently used in the market to realize remote control of electrical equipment, and what is controlled is the switch of the equipment; for lighting fixtures, the brightness of the light cannot be adjusted, which cannot satisfy the user's needs.
