Automatic temperature monitoring and constant current driving high power led supplied by PV/wind/grid hybrid system

摘要：

A kind of constant temperature and current operating high power LED module supplied by photovoltaic (PV)/wind/grid hybrid power system was designed in this paper. The LED was monitored while was controlled at room or lower temperature by a closed loop feedback circuit. An optimal PV/wind/grid complementary generation with lead-acid rechargeable battery was employed to supply the LED module. The maximum power point tracking (MPPT) scheme was adopted in the charging/discharging/unloading controller for the accumulator. Necessary computer software was programmed to perform technical tasks. The experimental result indicates that it’s benefit to improving luminescence when the LED is controlled by the designed circuit at low temperature.
