Solar Energy LED Lighting Design Based On DC Carrier Technology

Solar energy has attracted more attention as a clean, non-polluting and renewableenergy. It has expansive application prospect in the future. But, relative to the radiation ofenergy the conversion efficiency of solar power system is lower. In the past, the solarpower generation can’t be promoted because of the high cost. With the advance oftechnology, the price of photovoltaic devices has been reduced. So the photovoltaic powergeneration will be widely used in the practical engineering.This article designed a control equipment which puts the solar as a energy source forLED based on dc carrier technology. Through comparing several automatic trackingmethods for solar panels, it proposed the optimal scheme, and completed the hardware andsoftware design. Besides, this paper improves the output power by tracking the maximumpower point of solar power generation system; When processing the charging control ofsolar battery, the monitoring data is remotely transferred by DC carrier technology at thesame time. These monitoring data mainly include the temperature of the solar panel.output voltage, output current, battery voltage, and output current value. All of them aresent into control chip. And though the module of the DC carrier communication applied inthe field send the DC data with the DC power line to the master control module, throughthe LCD to display the data.The control scheme of LED lighting circuit mixes the sound and light method, realizethe remote on-off control by the switching circuit in master control module.
