1 / 38 page  September 2010 Doc ID 15473 Rev 2 1/38 AN2946 Application note Solar-LED streetlight controller with 25 W LED lamp driver and 85 W battery charger based on the STM32F101Rx Introduction The solar-LED streetlight controller described in this application note is designed to achieve an 85 W solar energy battery charger and a 25 W LED lamp driver. During the daytime the controller preserves the electricity energy gathered by the solar module (PV module), then stores it in the battery. In the evening the controller uses the battery energy to power the LED streetlight. When the battery runs out of power after several rainy days, the controller enables the external offline power supply (not included in this system) instead of the battery to power the LED streetlight until the system battery is fully charged again. Due to the clean nature of solar energy, and the highly efficient energy conversion of the PV module and very long operating life of the LED lamp, the solar-LED streetlight controller, compared to conventional streetlights, can save electricity remarkably, thus abating greenhouse gas (e.g. CO2) emission. This application note is based on the solution of solar-LED streetlight controller architecture, including a battery charger and LED lamp driver. The description of the architecture involves hardware and firmware design with design parameter settings. The solar-LED streetlight controller demonstration board is shown in Figure 1. Figure 1.
