Abstract

A LED melody decoration kit with multicolor light sources comprises an electrical wire with a plug-connector to get a voltage from a traditional lighting string, one or more LED lights to emit single or multiple lighting colors, and a cover package having a driving IC to drive and control the LED lights, which is directly applicable to change one of the incandescent lamps from a traditional lighting string for replacement, and which do not change the function of the original lighting string to emit single color or different multiple colors and obviously create plenty of effect in lighting string.

Claims

1. A LED melody decoration kit with multicolor light sources, comprising:

an electrical wire integrated with a plug-connector arranged to fit into one of a plurality of incandescent light sockets of a traditional lighting string including said plurality of incandescent light sockets, to get a voltage Vm from the traditional lighting string;

a control unit connected between the electrical wire and the one or more LED lights, said control unit having a driving IC that includes a driver circuit and a programmable control circuit for driving and controlling the LED lights, a voltage-multiplied and rectified circuit connected to the electrical wire to receive and double the voltage Vm from the plug-connector and obtain a pulse/surge voltage 2 Vm, and a constant voltage regulated circuit connected between the voltage-multiplied and rectified circuit and the driving IC to stabilize the pulse/surge voltage 2 Vm and input the pulse/surge voltage 2 Vm to the driving IC; and

one or more LED lights connected to be driven and controlled by the driver circuit and the programmable control circuit of the driving IC to emit single or multiple lighting colors.

2. The LED melody decoration kit with multicolor light sources as defined in claim 1, wherein the control unit further has a music device with horn which is driven and controlled by the driving IC.

3. The LED melody decoration kit with multicolor light sources as defined in claim 1, wherein the control unit has a hook for hanging the control unit from the traditional lighting string.

4. The LED melody decoration kit with multicolor light sources as defined in claim 2, wherein the control unit has a hook for hanging the control unit from the traditional lighting string.

5. The LED melody decoration kit with multicolor light sources as defined in claim 1, wherein the lighting color emitted from the one or more LED lights includes red, yellow, green, amber, blue, white or mixed with various changes in colors.

6. The LED melody decoration kit with multicolor light sources as defined in claim 1, wherein at least one of the at least one or more LED lights is covered with an outfit for decoration.

7. The LED melody decoration kit with multicolor light sources as defined in claim 1, wherein several of the LED lights are integrated with a flat ornament or card.

8. The LED melody decoration kit with multicolor light sources as defined in claim 1, wherein several of the LED lights are integrated with a three-dimensional pattern.
