LED LIGHTING DRIVER AND DRIVE METHOD

A driver is for driving a lighting load. A switch mode power converter is controlled in dependence on the input voltage, in particular so that the same current is delivered by a preset (fixed) switching mode at a first nominal operating voltage (Vr/2) and by a feedback (dynamic) switching mode at a...

Zusammenfassung:	A driver is for driving a lighting load. A switch mode power converter is controlled in dependence on the input voltage, in particular so that the same current is delivered by a preset (fixed) switching mode at a first nominal operating voltage (Vr/2) and by a feedback (dynamic) switching mode at a second nominal operating voltage (Vr). The first operating voltage corresponds to the voltage present when two drivers are connected in series across a power input, and the second operating voltage corresponds to the voltage present when a single driver is connected. 驱动器用于驱动照明负载。取决于输入电压来控制开关模式功率转换器，特别是使得在第一标称操作电压(Vr/2)处通过预设(固定)开关模式并且在第二标称操作电压(Vr)处通过反馈(动态)开关模式来传递相同的电流。第一操作电压对应于在电源输入两端串联连接两个驱动器时的电压预设，第二操作电压对应于连接一个驱动器时的电压预设。
