Dimming Control of a Smart LED Converter with Zigbee

A smart LED converter with a CC/CV setting was proposed. A dimming function, which adjusts the brightness of the LED by varying the current passing through it, enables users to dim the brightness of the lighting to desired levels and reduces unnecessary power consumption. Such a function was also added to this converter to maximize the energy consumption efficiency. We also used the Zigbee standard to wirelessly control multiple LED modules; this involved the construction of mesh networks in places such as underground parking lots and straight networks to control straight distances, such as those between streetlights. Finally, the control protocol for this setting was developed using MODBUS along with industrial PLC and MHI.
