摘要
结合农村道路路灯的特点及LED驱动电源发展的现状,设计了一款通用型小功率农村道路LED照明驱动电源。该设计基于BP3309路灯开关电源的设计方案,BP3309是一款单级、带有源功率因数校正的高精度原边反馈LED恒流控制芯片,适用于交流电压在85~265 V范围内输入的反激式隔离或升降压型非隔离的LED恒流电源。
Combined with characteristics of rural road lamps and development status of LED power supply,a general type of low power LED lighting power supply for rural roads was designed. Design was based on BP3309 street lamp switch power supply,BP3309 was a single stage power factor correction,a source of high precision original edge LED constant current feedback control chip,suitable for AC voltage between 85 ~ 265 V range input of type isolation or lifting pressed isolation of LED constant current power supply.
