    • A lighting system is provided that includes at least one lighting device, at least one connector, and a plurality of external power sources. The at least one lighting device includes at least one lighting source, and an internal power source applying a first electrical current to illuminate the at least one lighting element, wherein the internal power source supplies the first electrical current. The at least one connector electrically connects to the at least one lighting device. The plurality of external power sources include at least first and second external power sources that are adapted to be electrically connected to the at least one lighting device by the at least one connector. The first external power source supplies a second electrical current to the at least one lighting device to illuminate the at least one lighting source and the second external power source supplies a third electrical current to illuminate the at least one lighting source, such that the internal power source and one of the plurality of external power sources each supply electrical current to illuminate the at least one lighting source at different times.
    • 提供一种照明系统,其包括至少一个照明装置,至少一个连接器和多个外部电源。 所述至少一个照明装置包括至少一个照明源和施加第一电流以照亮所述至少一个照明元件的内部电源,其中所述内部电源提供所述第一电流。 所述至少一个连接器电连接到所述至少一个照明装置。 多个外部电源包括至少第一和第二外部电源,其适于通过至少一个连接器与至少一个照明装置电连接。 所述第一外部电源向所述至少一个照明装置提供第二电流以照亮所述至少一个照明源,并且所述第二外部电源提供第三电流以照亮所述至少一个照明源,使得所述内部功率 源和多个外部电源之一各自提供电流以在不同时间点亮至少一个照明源。
