摘要： An LED light string employs a plurality of LEDs wired in a series-parallel block. Further, each series-parallel block may be coupled in parallel, the parallel connection coupled across a supply voltage through an electrical interface. LEDs of the light string may comprise either a single color LED or an LED including multiple sub-dies, each sub-die of a different color. LED series-parallel blocks of the light string may be operated in continuous, periodic or pseudo-random state. The LED light string may provide polarized connectors to couple LED light strings end-to-end and in parallel with the supply voltage. The electrical interface may have one or more parallel outputs and a switch so as to operate multiple LED light strings in continuous, periodic or pseudo-random states. The LED light string may be adapted so as to employ LEDs of different drive voltages in each series section of the series-parallel block. Fiber optic bundles may be coupled to individual LEDs to diffuse LED light output in a predetermined manner.
摘要翻译： LED灯串采用串联在串并联块中的多个LED。此外，每个串联并联块可以并联耦合，并联连接通过电接口耦合在电源电压上。光束的LED可以包括单色LED或包括多个子模的LED，每个子模具具有不同的颜色。灯串的LED串并联块可以连续，周期性或伪随机状态操作。 LED灯串可以提供极化连接器以将LED灯串端对端并联并与电源电压耦合。电接口可以具有一个或多个并行输出和开关，以便以连续，周期性或伪随机状态操作多个LED灯串。 LED灯串可以适于在串联并联块的每个串联部分中使用不同驱动电压的LED。光纤束可以耦合到单独的LED以以预定方式扩散LED光输出。
