Abstract: A power interruption protection structure for an LED string light implements a Zener diode connected between an anode and a cathode inside or outside a casing of each of plural monochromatic or polychromatic LEDs that are connected in series to form the LED string light. In case of a burnout or breakdown of one of the LEDs, the Zener diode provided at the malfunctioning LED serves to instantly restore electrical conduction, allowing the LED string light to function normally without interruption. Accordingly, failure of one or some of the LEDs does not affect the LED string light as a whole.

Abstract: A color-changing light string comprises a plurality of color-changing luminous bodies connected in series, driven by a rectifier circuit and controlled by a control switch, so that each of the luminous bodies in the light string can emit lights of various colors individually, making the entire light string sparkle with vibrant and different colors and effectively enhancing visual effects of the light string as is not seen in conventional light strings.

Abstract: An optical fiber light-transmissive structure especially suitable for decorative objects and capable of displaying splendid light effects, is formed by rolling process applied at any appropriate position of an optical fiber cord, so as to produce sophisticated changes at refracting planes at an interior of the optical fiber cord. Using the structure according to the invention, light beams entering into an input end of the optical fiber cord are able to show dazzling light effects at a light-emitting segment formed, thereby achieving results such as increasing a light-emitting area thereof, providing flexible arrangement of the light-emitting segment, and displaying artistic and lively light effects.

Abstract: A compound color LED comprises a light-and-off controller IC, a plurality of different colored mini-LEDs, and a variable resistor; each of the components is installed into a transparent light body of a LED of regular size, and the light-and-off controller IC is driven by using a direct current of low voltage between 3˜4.5V, and the output of the light-and-off controller IC controls each mini-LED to produce the on and off lighting effect, so that the lamp of the present invention emits colorful light with glistering variation to attain the effect of producing a variety of colored light by means of a single common LED lamp.

Abstract: A light emitting device for optic fiber decoration, comprising a flash control IC, a plurality of different colored LED's, a variable resistor and a light-sensitive resistor, driven by 4.5V DC voltage to control the flash control IC, with output from the flash control IC controlling each LED to produce alternated and gradually changing flashing lights. Each LED projects lights into the optic fiber, producing romantic light changes to the optic fiber decoration. The invention can be used to replace the light-emitting device, including light bulbs, a motor, color discs and such sophisticated structures in a conventional optic fiber decoration, for the effects of safer use, more energy saving and higher efficiency than conventional types.

Abstract: A water-resistant base device for optical-fiber Christmas trees, consisting of a main base unit, a upper base cover, a rotating unit, a fixing unit, a water-resistant hood, a top cover and a tree unit. The rotating unit is installed on the fixing unit structure on the upper cover of the base, using a ringed wall protruding from the top periphery of the main base unit, the water-resistant hood fastened onto the top of the upper base cover, and the arched top cover covering the top of the water-resistant hood, to enable heat radiation and water resistant functions to the entire base assembly, so the Christmas tree can be installed for indoor and outdoor purposes.

Abstract: An artificial tree structure with decorative lamps, comprising a plurality of hollow tubes or iron wires of various lengths, in the shape of tree branches, arranged from top to bottom around the main trunk supported by detachable legs. On each side sticks are installed a plurality of iron wires to form the shape of tree branches. The exterior of the hollow tubes or iron wires is wound by dense tree leaves. The lamps installed in the hollow tubes or on the iron wires are serially connected to become decorative lamp strings. The decorative lamp strings are then combined in parallel connection, running down the main trunk to be connected to a control box and a power transformer. The structure described above provides the artificial tree with decorative lamps, using the control box to produce music and lighting effects of different luminosity and flashing speeds.

Abstract: An angel doll for displaying on a table or mounted on a Christmas tree in Christmas season or such occasion includes a slow transmission device inside a base. The transmission includes a main shaft that drives a palette, two rotating cylinders and two rotating rods, so the palette rotates slowly, and colorful rays can be projected from the lamp inside the base, through the two rotating cylinders, to the margins of the optical fiber wing units. The swinging movement activated by the two rotating cylinders and the two rotating rods through the connecting rods and the side shaft in linkage, causes the wing units and the arm units to swing reciprocally, creating an active and lively atmosphere to the angel doll.
