Abstract: An LED Christmas lamp includes a lamp base, in which a receiving cavity is formed and having coupling slots formed in a cavity wall to receive and retain metal plates on ends of four conductive wires. A light source holder has a top forming a light disposition section, in which three receiving holes are formed and has a bottom on which a fitting section having four bearing surfaces is formed. The fitting section has a bottom face including six through apertures. Three LED illuminants are provided, each having two terminal pins, and are respectively inserted into the three receiving holes with the terminal pins bent and positioned against the bearing surfaces of the fitting section so that when the light source holder is inserted into the receiving cavity, the terminal pins are set in electrical engagement with the metal plates of the conductive wires.

Abstract: The present invention relates to a programmable controller of light string characterized in that the controller of light string is provided with a bluetooth receiver and a main IC electronically connected with the bluetooth receiver so as to further corporate with a smart phone to download a new song or music and then transmit it through the bluetooth of the smart phone to the bluetooth receiver. The rhythm of the new song or music is converted to signals by the main IC of the controller for controlling the flashing of all light bulbs at the corresponding rhythm. Thereby the light string is able to change the flashing pattern of light bulbs in association with the update of a song or music that varies the flashing effect of light string in a broad range of variety.

Abstract: The present invention provides a light string with diversified lighting, mainly disposing a controller having multiple blink and jump models on a electric wire at power supply leading edge of a light string formed by combining a plurality of lamp strings strung with several lamps together, thereby to allow the lighting of lamps on all lamp strings of the whole light string to change, blink and jump vertically and levelly simultaneously through the controller 20 in operation with the main control IC to achieve a more dazzling and appealing lighting effect.

Abstract: An LED Christmas lamp string includes a lamp base that has a bottom end receiving lamp string conductor wires to extend therein and covered by a bottom lid. The lamp string conductor wires form four segments inside the lamp base to respectively connect to terminal pieces. A circuit component board has an upper surface to which light-emitting elements and four circuit pins are mounted and a lower surface to which a control IC is mounted. The circuit component board is positioned on a socket to allow the circuit pins to extend through the socket to be bent to attach to projecting blocks of the socket. The socket is fit into the lamp base to have the circuit pins engage the terminal pieces for electrical connection. A light-transmitting cover is then set to cover the circuit component board. A decoration cap is fit to and coupled to the lamp base.
