Abstract

A high power light string device comprises a plug with a plug blade set, a tail receptacle, and at least an LED string, wherein a first power adaptor disposed in the plug converts an AC voltage through the plug blade set to a high DC voltage, and a second power adaptor disposed in the tail receptacle converts the AC voltage through the plug blade set to a low DC voltage. Two ends of the LED string are respectively connected to the first and second power adaptors to receive the high and lower DC voltages so that the LED string is turned on to emit light. The power adaptors are directly disposed respectively in the plug and the tail receptacle to simplify the whole light string device so as to enhance the decorating effect of the light string device.

Claims (11)

1. A high power light string device comprising:

a plug having a first plug blade set and a first power adaptor, wherein said first power adaptor is disposed in said plug to convert an AC voltage through said first plug blade set to a high DC voltage;

a tail receptacle having a conducting strip set and a second power adaptor disposed interiorly, said second power adaptor converting said AC voltage through said first plug blade set to a low DC voltage; and

at least an LED string having a first end and a second end, said first end being connected to said first power adaptor to receive said high DC voltage and said second end being connected to said second power adaptor to receive said low DC voltage so that said LED string is turned on to emit light.

2. The high power light string device as claimed in claim 1 , wherein said conducting-strip set is electrically plugged by a second plug blade set of a second plug.

3. The high power light string device as claimed in claim 1 , wherein said conducting-strip set is electrically connected to said second power adaptor.

4. The high power light string device as claimed in claim 1 , wherein said conducting-strip set is electrically connected to said first plug blade set.

5. The high power light string device as claimed in claim 1 , wherein said plug and said tail receptacle are driven at the same voltage.

6. The high power light string device as claimed in claim 1 , wherein a fuse component is further disposed in said plug, and said fuse component is electrically connected to said first power adaptor and said first plug blade set.

7. The high power light string device as claimed in claim 1 , wherein said plug and said tail receptacle are made of plastic material.

8. The high power light string device as claimed in claim 1 , wherein each LED of said LED string is selected among a white LED, a red LED, a blue LED, a green LED, a yellow LED, and a LED of another color.
