Circuit to keep electronic transformers working while under-loaded

Abstract:

An LED light source includes a sub-circuit (24) that is connectable via terminals (12,13) to an electronic transformer and to a powered circuit including at least one LED (4). The sub-circuit (24) includes a sub-circuit rectifier (1a, 1b, 1c, 1d) that is connectable to the transformer (25), and a constant current regulator (7) and a sub-circuit capacitor (6) that are connected parallel to the sub-circuit rectifier (1a, 1b, 1c, 1d).

Abstract(Chinese):

LED光源包括可经由端子（12,13）连接到电子变压器和包括至少一个LED（4）的供电电路的子电路（24）。子电路（24）包括可连接到变压器（25）的子电路整流器（1a，1b，1c，1d）和恒流调节器（7）和子电路电容器（6），其中并联连接到子电路整流器（1a，1b，1c，1d）。
