用于LED灯的交流和直流驱动器结构的灯引擎
摘要：
一种灯引擎包括串联耦合的多个第一二极管。多个第一二极管包括第一阳极端和第一阴极端。多个第二二极管串联耦合。多个第二二极管包括第二阳极端和第二阴极端。第一端子电耦合到所述第一阴极端和所述第二阳极端，以形成第一节点。第二端子耦合到所述第一阳极端。多个第三二极管串联耦合。多个第二二极管包括第三阳极端和第三阴极端。第三端子耦合到第三阴极端。第四端子电耦合到所述第二阴极端和所述第三阳极端，以形成第一节点。
摘要（英）：

A light engine includes a first plurality of diodes coupled in series. The first plurality of diodes includes a first anode end and a first cathode end. A second plurality of diodes is coupled in series. The second plurality of diodes includes a second anode end and a second cathode end. A first terminal is electrically coupled to the first cathode end and said second anode end to form a first node. The second terminal is coupled to said first anode end. A third plurality of diodes is coupled in series. The second plurality of diodes includes a third anode end and a third cathode end. The third terminal is coupled to the third cathode end. A fourth terminal is electrically coupled to the second cathode end and the third anode end to form a first node.
