Description

technical field

[0001] The invention relates to an LED dimming driver, in particular to a networked high-power group LED intelligent dimming driver. Background technique

[0002] Lighting energy consumption occupies a pivotal position in the entire electricity consumption. According to the data from the US Department of Energy, 22% of the electricity consumption in the United States is in the lighting field. It is even worse in China. Taking Shanghai as an example, lighting electricity consumption accounts for more than 1 / 3 of the city's electricity consumption. A lighting revolution that is both energy-saving and environmentally friendly is imminent. Semiconductor lighting (LED lighting) is a new generation of cold light source developed in the 1990s. It has incomparable advantages over traditional light sources: energy saving, environmental protection (no harmful substances such as mercury), long life (50,000 hours), Reducing maintenance costs, providing better light qual...
