Now LED lamps have become the dominant light source in lighting systems due to their high luminous efficiency and longer service life. The development of information technology has led to the popularization and widespread implementation of various smart devices, including smart lighting systems. In this regard, the demand for brightness control of LED light sources is also increasing. This article considers the features of brightness control for LED lamps powered by AC, the problems that arise in this case, analyzes their main causes. The main attention is paid to the phase-cut dimming method, an approach to its application for brightness control is considered, which ensures a change in brightness in accordance with its human perception, a dimmer circuit for its implementation is proposed.
