  • Patent number: 9121581
    Abstract: The present invention proposes a LED Christmas light, using an LED bulb with four connection pins to insert in a soft core configured with four through holes allowing the four connection pins to be passed through and bended configured on the bottom thereof, and the soft core being inserted in a soft head with four convex plates in pairs face-to-face and extended to the bottom face thereof configured on the inside thereof, where an engagement space is formed between each two adjacent convex plates in the soft head, allowing four metal conducting sheets with a conducting wire to be engaged therewith, and a blocking plate adapted to isolate the conducting wire of each metal conducting sheet is configured on the center of a face of each convex plate, thereby allowing one LED Christmas light unit to use an LED bulb with a light source of more than four colors.

  • Patent number: 8803429
    Abstract: The present invention provides a structure of color mixing circuit of LED light. The LED light includes two input terminals and two output terminals. The two input terminals are respectively an input terminal of reverse parallel connection of any two light-emitting chips of three primary-color light-emitting chips of R, G, B and an anode input terminal of the remaining light-emitting chip and the two output terminals are respectively an output terminal of reverse parallel connection of any two light-emitting chips of the three primary-color light-emitting chips of R, G, B and a cathode output terminal of the remaining light-emitting chip. The structure is simple and the purposes of reducing the number of IC control chips and synchronous color change of light-emitting chips are achieved with modification only made on electrical connection among the three primary-color light-emitting chips in realizing operation of a group of LED lights connected in series.

  • Publication number: 20100109538
    Abstract: The invention relates to a continuous current control circuit module of series string bulbs type, which can maintain the normal current and voltage across each of the bulbs when any of series connected bulbs burn out. The string includes a shunt in every bulb assemblies, which is especially a Zener diode with a tiny volume. The shunt will thus provide a secure electrical connection of the light string whenever any bulb is burn out or broken.
