  • Patent number: 10744692
    Abstract: An extrusion molding machine for manufacturing the spiral bicolor LED hose light just needs a single process and equipment to greatly increase the production efficiency and save the equipment investment costs. The input channel terminal of the second flow channel connected with a first horizontal channel is gradually smaller, and the transportation end terminal of the first horizontal channel connected with a second horizontal channel of larger diameter is gradually larger. The transportation end terminal of the second extruder is connected with the input terminal of the third flow channels. The light strip input channel inputs the LED light strip to pass through the first and second flow channel, which the transparent molten plastic squeezed by the first extruder wraps and covers the LED light strip and the molten plastic with the other color squeezed by the second extruder is spirally wounded on the surface of the transparent molten plastic.

  • Patent number: 10641444
    Abstract: A SMT LED light string which the ICs with IDs are embedded in the light beads; wherein the light string is formed by connecting a plurality of SMT LED light beads which the IC control chips with IDs are set inside. All of the corresponding IC control chips with IDs for the SMT LED light beads can be controlled because the IC control chips with IDs are set in the SMT LED light beads. Therefore, the stable and orderly flashing can be achieved, and the lighting effects such as the line-up, the progression, and the chasing . . . , etc. can also be made. No matter for a monochrome light string or a colored light string, the effective control can both be achieved to make the various lighting effects because the IC control chips with IDs are set in the SMT LED light beads.

  • Patent number: 9635722
    Abstract: The string light contains three copper wires and a number of lighting units and each lighting unit contains at least two surface-mount-device (SMD) light emitting diodes (LEDs). A first wire and a second wire are connected to a positive terminal and a negative terminal of a power source, respectively. Within each lighting unit, a first SMD LED has its anode connected to the first wire, a second SMD LED has its cathode connected to the second wire, and the first and second SMD LEDs have their cathode and anode connected to a third wire, respectively. The string light is capable of withstanding stronger pull by employing three wires. The parallel-connected lighting units and the series-connected SMD LEDs within each lighting unit significantly reduce the effect of voltage drop.
