Abstract: An LED light string employs a plurality of LEDs wired in block series-parallel, where the one or more series blocks, each driven at the same input voltage as the source voltage (110 VAC or 220 VAC), are coupled in parallel. The LED light string interfaces to the source voltage using a common household plug; it may also include a corresponding common, household socket, coupled in electrical parallel, to enable multiple light strings to be connected to each other from end to end. In order to directly drive a network of diodes without current-limiting circuitry, the voltage of each series block of diodes must be matched to the input source voltage. This voltage matching requirement for direct AC drive places fundamental restrictions on the number of diodes on each diode series block, depending on the types of diodes used. For the voltage to be “matched,” in each series block, the peak input voltage must be less than or equal to the sum of the maximum diode voltages for each series block.

Abstract translation: LED灯串使用串联并联的多个LED，其中以与源电压（110VAC或220VAC）相同的输入电压驱动的一个或多个串联块并​​联耦合。 LED灯串使用普通家用插头连接到源电压; 它还可以包括相互并联的相应的公用家用插座，以使得多个灯串可以从一端到另一端相互连接。 为了直接驱动没有限流电路的二极管网络，每个串联二极管的电压必须与输入源电压相匹配。 根据所使用的二极管的类型，直流交流驱动器的这种电压匹配要求对每个二极管串联模块上的二极管数量做出了基本的限制。 对于每个串联块中的“匹配”电压，峰值输入电压必须小于或等于每个串联块的最大二极管电压之和。
