    摘要： A power supply apparatus (1) for string light (400) includes a power cable (100), a switching circuit (200), a power transformer (300), and a casing (331). The switching circuit (200) is electrically connected to two wires (112) of the power cable (100) to selectively form a voltage grading between the two wires (112). The power transformer (300) includes a power transforming circuit (310) and a control circuit (320). The power transforming circuit (310) receives an external power (Ve) via an input terminal (311), transforms the external power (Ve) into a driving power (Vout), and outputs the driving power (Vout) via an output terminal (312). The receiving end (101) of the power cable (100) is electrically connected to the output terminal (312). The control circuit (320) detects a voltage grading status between the two wires (112), and generates a switch signal to the power transforming circuit (310) to modulate the driving power (Vout). The power transforming circuit (310) and the control circuit (320) are disposed within the casing (331) and the power cable (100) is disposed outside the casing (331).

    摘要： The invention relates to an electrical coupling device (110) for coupling functional elements (50) of a lighting system (200), wherein the electrical coupling device (110) comprises a first wire (11), a second wire (22), at least one spacer (20) and at least one coupling spacer (22). The at least one spacer (20) is arranged to provide a first defined distance between the first wire (11) and the second wire (12) at the position of the spacer (20). The coupling spacer (22) is arranged to provide a second defined distance between the first wire (11) and the second wire (12) at the position of the coupling spacer (22). The coupling spacer (22) is further arranged to electrically couple the functional element (50) to the electrically coupling device (110), wherein the at least one spacer (20) and the coupling spacer (22) are physically separated from each other, and wherein the at least one coupling spacer (22), the at least one spacer (20), the first wire (11) and the second wire (12) are embedded in a flexible cover (30). The coupling device (110) embedded in the flexible cover (30) enables flexibility in all three dimensions at a position between the at least one spacer (20) and the at least one coupling spacer (22).
    The invention further relates to a lighting system (200) comprising such an electrical coupling device (110) and a functional element (50).

    摘要： An LED flexible wire light in parallel-series connection comprises: first flexible wire, second flexible wire, third flexible wire, and a plurality of SMD LED groups; said first flexible wire, said second flexible wire and said third flexible wire are enclosed by non-conductive material without any conduction each other; said plurality of SMD LED groups are numbered as first SMD LED group, second SMD LED group, ..., Nth SMD LED group; said SMD LED groups with odd numbers are odd SMD LED groups, said SMD LED groups with even numbers are even SMD LED groups; said plurality of SMD LED groups are electrically connected between said first flexible wire and said second flexible wire in order of said SMD LED groups' number; said third flexible wire is the cathode of said LED flexible wire light, and said first flexible wire is the anode of said LED flexible wire light. The manual welding connection is reduced. The efficiency is higher to down the manufacture cost. And the resistance to tension of lights in parallel-series connection is enhanced. Thus, the LED flexible wire light in series-parallel connection can be manufactured in mass.
