The present invention provides a polarized quick plug having replaceable fuse. The cable is fixed on the rear end of the inner seat by the breaking plates and the rear cover, so the inner seat has sufficient space to receive two fuses. The housing further has a window corresponding to the two fuses, and a movable plate is arranged at the window to selectively cover the window. The user can open the movable plate to exchange the working fuse and the spare fuse.

A high voltage controller contains: a casing and a wire receiving orifice defined on a predetermined position of the casing and configured to receive a preferred wire and to connect with a predetermined light-emitting diode (LED) light source. The casing further includes an electric circuit board accommodated therein, and the electric current board includes a wave filter, a rectifier, an inverter which are arranged from a voltage input end to a voltage output end of the electric circuit board, such that the wave filter and the rectifier rectify electric currents, and an alternating current (AC) voltage is rectified into a direct current (DC) voltage. The inverter includes at least one transistor arranged in a matrix so as to invert into the AC voltage, and the AC voltage is outputted, hence the AC voltage and the DC voltage are transformed repeatedly to obtain no-shaking lights.

Disclosed is an LED light string power adapter having a valley-fill circuit, comprising a shell and a plug arranged at a predetermined position of the shell. An energy-saving circuit board is arranged in the shell; the energy-saving circuit board sequentially comprises a filtering device, a rectifying device, a valley-fill circuit, and a transformer from a voltage input end to a voltage output end. The valley-fill circuit is located between the rectifying device and the transformer; the conduction angle of a rectifying tube is greatly increased by using the valley-fill circuit after the rectifying device; by filling a valley point, input current is changed from a spike pulse to a waveform close to that of a sine wave, a power factor becomes very close to 0.7 or more, the total harmonic distortion is remarkably reduced, and thus the advantages of reducing input loss and saving energy are achieved.
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.
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.
