Abstract: The present invention relates to a multi-mode series light controlling system, including a main control device that includes a front plug, a control unit, a mode switching key, a tail plug, and a connection module. The tail plug is electrically connected to the front plug through the control unit. The connection module is able to connect with multiple series lights simultaneously. The front plug is used to connect an AC power source. The control unit generates a lighting control signal according to the mode switching key and provides it to the connection module through the tail plug. The main control device provides functions to control multiple series light to switch between on, off, and different lighting patterns. Therefore, the controlling system is a progressive replacement for multiple control switches for multiple series light, achieving the purpose of managing series lights with one device.

Abstract: A light string with a non-extinguishing function and an independent LED blinking function includes an LED light string having a plurality of LED bidirectional lamp groups and a plurality of LED independent blinking lamp groups connected in series, and a switchable-polarity power supply connected to the LED light string for providing a pair of DC voltages with switchable polarity to the LED light string. The LED bidirectional lamp group includes a plurality of LED bidirectional lamps connected in parallel, and the LED independent blinking lamp group includes a blinking control circuit and a plurality of LED bidirectional lamps connected in parallel. The plurality of LED bidirectional lamps may be a plurality of LED two-color bidirectional lamps or LED mono-color bidirectional lamps; and the blinking control circuit controls the plurality of LED bidirectional lamps to blink independently and to cyclically vary the brightness of the plurality of LED bidirectional lamps.

Abstract: A multi-color light apparatus is provided and includes a power adapter, a power switch and a plurality of light bulbs. The power adapter has a converter to convert AC power to DC power. The power switch is electrically connected to the power adapter and includes a controller to provide a plurality of time division multiplexed signals. The light bulbs receive the time division multiplexed signals and are configured to perform different illumination effects in accordance with the time division multiplexed signals. By using the multi-color light apparatus, only two power wires are used so as to simplify the manufacture of the multi-color light apparatus and reduce the cost of the manufacture.

Abstract: An electrical connector includes a male insertion piece and a female insertion piece. The male insertion piece has an insulation base, an insulation tube being hollow and formed on one end of the insulation base, an outer electrode securely mounted around the insulation tube, and a conductive needle mounted in the insulation tube. The female insertion piece has an insulation sleeve having a guiding slot for the insulation tube to be inserted therein, an outer connection electrode mounted inside the insulation sleeve and mounted around the outer electrode, and an inner connection electrode having a first conductive part abutting against a top portion of the conductive needle and at least two second conductive parts holding two lateral portions of the conductive needle. When the male insertion piece engages the female insertion piece, there are at least three contact positions forming a firm and stable triangular connection.

Abstract: Provided is a quick mount connector assembly of an artificial Christmas tree, the connector assembly including: a male connector and a female connector. The male connector has a male shell that has a plug end, an electrical connection shaft being cylindrical and extending outward from the plug end, a through hole, and a clamping pin installed in the through hole. The female connector is detachably connected to the male connector and has a female shell detachably connected to the male shell and having an electrical connection hole receiving the electrical connection shaft for building an electrical connection, a through hole, and a clamping pin installed in the through hole of the female shell. When any one of the connectors is broken, the broken connector can be quickly dismantled and repaired because the shells are detachable. The connector assembly is suitable for both DC and AC currents.
