Abstract: An LED lighting includes an LED lamp, a connecting wire, and a connecting copper sheet used to connect the LED lamp and the connecting wire. The connecting copper sheet includes a first fixing sheet used to connect with the pin of the LED lamp, a second fixing sheet used to connect with the core wire of the connecting wire, a third fixing sheet used to connect with the sheath of the connecting wire, and a copper strip for connecting the first fixing sheet and the second fixing sheet. The length of the third fixing sheet is longer than that of the second fixing sheet. The width of the third fixing sheet is shorter than that of the second fixing sheet. The third fixing sheet is concatenated with the second fixing sheet, and the connecting copper sheet is sheathed with an insulating sleeve.

Abstract: A controller structure is applied to electrically conduct at least one LED light string and contains: a control box, a high voltage circuit unit, and a lid. The control box includes an opening, a hollow accommodation portion, two pins, and a first fitting portion. The high voltage circuit unit is accommodated in the hollow accommodated portion and includes an input segment and an output segment, a positive-electrode contact and a negative-electrode contact of the input segment are electrically connected with the two pins, a positive-electrode contact and a negative-electrode contact of the output segment are electrically connected with at least two power wires, and the high voltage circuit unit further includes a control unit. The lid covers the opening and includes a socket and a connection portion which is electrically connected with the output segment of the high voltage circuit unit via the at least two power wires.

Abstract: A power supply of a transformer outputs alternating current (AC) and direct current (DC) and contains: a housing and a lid for covering a first end of the housing. An input interface is formed on a second end of the housing, and the lid includes a DC output interface and an AC output interface. A light string contains a power supply of a transformer and a light emitting unit, the power supply outputs alternating currents (AC) and direct currents (DC), and the power supply contains: a housing and a lid for covering a first end of the housing. An input interface is formed on a second end of the housing, the lid includes a DC output interface and an AC output interface, and the DC output interface couples with a DC output connector, and the DC output connector connects with plural bulbs of the light string.
