Description

technical field

[0001] The invention relates to the technical field of drivers, in particular to a driver for road lighting LEDs based on network control. Background technique

[0002] Lamps using high-power LED light-emitting devices have the characteristics of low power consumption, flexible control, high luminous efficiency, and long life. Currently, they are widely used in urban roads, tunnels, squares, parks, factories and other places that require outdoor lighting. At the same time, LED street lights can be combined with wind power generation equipment, solar power generation equipment and energy storage equipment to form a wind-solar complementary lighting system, further exerting the advantages of green environmental protection, which is of great significance to urban lighting energy saving. In order to meet the needs of urban road lighting, usually a road needs to be equipped with a large number of street lights, which are divided into several light groups according...
