LIGHTING DRIVER AND DRIVE METHOD

A lighting driver has a switch mode power converter, and a detect arrangement for detecting if the driver is in a single mode and connected across the external power source alone or is in a dual mode and connected across the external power source in series with another driver. A valley fill circuit...

description A lighting driver has a switch mode power converter, and a detect arrangement for detecting if the driver is in a single mode and connected across the external power source alone or is in a dual mode and connected across the external power source in series with another driver. A valley fill circuit is provided between the power input and the switch mode power converter. The valley fill circuit is enabled for the single mode and disabled for the dual mode. 一种照明驱动器,具有开关模式功率转换器,以及检测装置,用于检测驱动器是处于单模式并单独跨接在外部电源上,还是处于双模式并与另一驱动器串联跨接在外部电源上。在功率输入与开关模式功率转换器之间提供填谷电路。填谷电路在单模式下启用,并且在双模式下禁用。
