Network control-based driver for road lighting LED

Abstract

The invention discloses a network control-based driver for a road lighting LED. The network control-based driver comprises an EMI input filter circuit, a PFC power factor correction circuit, an LLC variable-frequency conversion circuit, a control module and an RF module, wherein an input end of the EMI input filter circuit is electrically connected with electric supply; an output end of the EMI input filter circuit is electrically connected with the input end of the PFC power factor correction circuit; the output end of the PFC power factor correction circuit is electrically connected with the input end of the LLC variable-frequency conversion circuit; the output end of the LLC variable-frequency conversion circuit is electrically connected with an LED lamp; the control module is electrically connected with the RF module, a control end of the EMI input filter circuit and the control end of the LLC variable-frequency conversion circuit; and a radiator is also arranged on the driver. The network control-based driver for the road lighting LED can achieve the functions of timing control, dimming control, data wireless transmission and the like of the road lighting LED; and the power factor and the efficiency are improved.

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...

Problems solved by technology

At present, the drivers used for road lighting LEDs only have simple driving functions, without functions such as timing control, dimming control, parameter monitoring and data wireless transmission, and the power factor and efficiency are also insufficient.
