Abstract: A method and a power supply for use with a light emitting diode (LED) module is provided. A power factor correction (PFC) circuit switches a flyback converter to provide power supplied to the LED module. A current controller is for monitoring voltage and/or current for operation of the LED module and determining a feedback for correcting the voltage and/or current to provide constant light output of the LED module. The feedback is provided to the PFC circuit via a feedback circuit having an optical isolation device for providing isolation between the primary and the secondary side of the flyback converter. The feedback may be adjusted by sinking or sourcing current to or from the feedback circuit.
Abstract translation: 提供了一种与发光二极管（LED）模块一起使用的方法和电源。 功率因数校正（PFC）电路切换回扫转换器以提供提供给LED模块的电力。 电流控制器用于监测用于LED模块的操作的电压和/或电流，并且确定用于校正电压和/或电流的反馈以提供LED模块的恒定的光输出。 反馈通过具有光隔离装置的反馈电路提供给PFC电路，用于在反激式转换器的主侧和次侧之间提供隔离。 可以通过向或从反馈电路吸收或提取电流来调整反馈。

Abstract: A method and apparatus for controlling a streetlight is provided. GPS data is required from a GPS coupled to a process of the streetlight. A geographic location of the streetlight is determined from the received GPS data. A real local time is determined from the GPS data and a sunrise and sunset time associated with the geographic location can then be determined. The on and off state of one or more LED lighting modules of the streetlight can then be controlled upon the determined sunrise and sunset times.
Abstract translation: 提供了一种用于控制路灯的方法和装置。 从与路灯过程相连的GPS需要GPS数据。 从所接收的GPS数据确定路灯的地理位置。 从GPS数据确定真正的本地时间，然后可以确定与地理位置相关联的日出和日落时间。 然后可以根据确定的日出和日落时间来控制路灯的一个或多个LED照明模块的开和关状态。

Abstract: A high efficiency light emitting diode power supply for roadway lighting fixtures is provided. The power supply enables conditioning and monitoring of input power and monitors LEDs current to ensures consistent performance of the LED by changing a power correction factor. The LED output can also be adjusted based upon age or external input parameters and by modifying the power correction factor value. In addition, the LED output can be dimmed, turned down in output to a lower level at any time of night for a prescribed duration in order to further save energy. This dimming function uses a programming scheme that keeps track of the "seasons" (summer, fall, winter and spring) so that time of night is tracked accurately all year long.
Abstract translation: 提供了用于道路照明装置的高效率发光二极管电源。 该电源支持对输入功率进行调节和监控，并监控LED电流，通过改变功率校正系数确保LED性能一致。 LED输出也可以根据年龄或外部输入参数以及修改功率校正系数值进行调整。 此外，LED输出可以调暗，在任何时间夜间在任意时间输出到较低的电平，持续规定的时间，以进一步节省能源。 这种调光功能采用编程方案，可以跟踪“季节”（夏季，秋季，冬季和春季），以便整夜准确地跟踪夜间时间。
