Abstract

A seven-color light emitting module and a seven-color decorating lamp string comprising the same. The seven-color light emitting module includes a lampshade made of a transparent plastic or synthetic resin, and a lamp socket on which three colors self-flashing light emitting diode, a zener diode, a current limiting resistance and a double-side printed circuit board (PCB) are sealed. The three colors light emitting diodes connect with PCB and connect with the zener diode in parallel. One end of the zener diode or two ends of the zener diode connects with the current limiting resistance in series. A transparent epoxy resin or silicon glue is filled in the lampshade. The seven-color decorating lamp string include a power supply plugs, a power supply module which has a PCB and a rectifying and filter circuit connected by wires and a plurality of said seven colors light emitting modules.

Claims

1. A seven-color light-emitting module, comprising

a lampshade;

and

a lamp socket;

wherein

said lampshade is made of ivory-white light-transmission plastics or synthetic resin with good color-mixing effect and transparency;

a three-color self-flashing LED, a Zener diode, a current-limiting resistor and a printed circuit board (PCB) sealed in said lampshade are disposed on said lamp socket;

said three-color self-flashing LED is connected with said PCB, and both ends of said three-color self-flashing LED are parallel connected to said Zener diode;

one or both ends of said Zener diode are serially connected to said current-limiting resistor; and

said lampshade is filled with transparent epoxy resin or silicon glue.

2. The seven-color light-emitting module of claim 1, wherein

said PCB is a double-side PCB;

and

said Zener diode and said current-limiting resistor disposed thereon are piece components.

3. The seven-color light-emitting module of claim 1, wherein one or two three-color self-flashing LEDs are disposed in said lampshade.

4. The seven-color light-emitting module of claim 1, wherein a transparent sealing layer for sealing said three-color self-flashing LED, said PCB and said piece components on said PCB is disposed in said lampshade.

5. The seven-color light-emitting module of claim 1, wherein a thickness of said lampshade is 2-12 mm.

6. The seven-color light-emitting module of claim 1, wherein a positioning hole is axially disposed on a side wall at the bottom of said lampshade.

7. The seven-color light-emitting module of claim 1, wherein said lampshade is a sphere, a column, a rectangle, a rhombus, a lantern, or a shape of an animal.

8. The seven-color light-emitting module of claim 1, wherein said lampshade and said lamp socket is integrally formed into a sphere, a column, a rectangle, a rhombus, a lantern, or a shape of an animal.

9. A seven-color decorating lamp string, comprising

a plug;

and

a power supply and a plurality of seven-color light-emitting modules connected via wires;

wherein

said power supply comprises a house filled epoxy resin or silicon glue and a rectifying and filter circuit connected to a printed circuit board (PCB);

said seven-color light-emitting module comprises a lampshade, a lamp socket, and a three-color self-flashing LED, a Zener diode, a current-limiting resistor and said PCB disposed on said lamp socket and sealed in said lampshade;

said three-color self-flashing LED is connected with said PCB, and both ends of said three-color self-flashing LED are parallel connected to said Zener diode;

one or both ends of said Zener diode are serially connected to said current-limiting resistor; and

said lampshade is filled with transparent epoxy resin or silicon glue.

10. The seven-color decorating lamp string of claim 9, wherein a plurality of said seven-color decorating lamp strings can be connected altogether in structure to form a lamp string with hundreds to thousands of seven-color light-emitting modules.
