Holiday LED lighting system and methods of use

1. An adapter comprising:

a first end comprising an adapter plug;

a second end comprising an adapter outlet; and

a rectifier placed between one side of the adapter plug and the corresponding side of the adapter outlet, wherein the other side of the adapter is non-rectified, the adapter is configured to receive a plug of a light string, wherein the plug of the light string is plugged into the adapter at orientations to adjust current flow.

2. A method of using the adapter of claim 1 to half-rectify the electrical current passing through a wired system, said method comprising:

connecting the adapter to a power means;

connecting a plug of a wired system into the adapter outlet in a first orientation, wherein when the plug of the wired system is in the first orientation, the rectifier allows passage of a half-rectified wave that is passed through the wired system for at least a first set of parallel wired elements; and

connecting the plug of the wired system into the adapter outlet in a second orientation, wherein when the plug of the wired system is in the second orientation, the rectifier allows passage of a half-rectified wave that is passed through the wired system for at least a second set of parallel wired elements.

3. The adapter of claim 1 , wherein the adapter is polarized.

4. The adapter of claim 1 , wherein the adapter is non-polarized.

5. The adapter of claim 1 , wherein the adapter comprises a second outlet.

6. A decorative light system comprising:

at least one light string comprising a first end comprising a plug, a second end comprising a receptacle to receive a plug electrically connected to the plug of the first end , and a plurality of light bulbs dispersed between the first end and the second end, each light bulb arranged electrically in series, the light bulbs comprising at least two LED chips, wherein at least one LED chip is connected in parallel and at least one LED chip is connected in reverse parallel; and

an adapter comprising a first end comprising an adapter plug, a second end comprising an adapter outlet, and a rectifier placed between one side of the adapter plug and the corresponding side of the adapter outlet, wherein the other side of the adapter is non-rectified and wherein the plug of the light string is plugged into the adapter outlet and the adapter plug is connected to a power source; and wherein if the plug of the light string is plugged into the adapter outlet in a first orientation, the first LED chip is forward biased relative to the second LED chip, lighting the LEDs connected in parallel according to the first LED chip and wherein if the plug of the light string is plugged into the adapter outlet in a second orientation, the second LED chip is forward biased relative to the first LED chip, lighting the LEDs connected in parallel according to the second LED chip, wherein the plug of the light string is plugged into the adapter at orientations to adjust current flow.

7. The decorative light system according to claim 6 , further comprising a plurality of light strings electrically connected in series.

8. The decorative light system according to claim 6 , further comprising at least one current limiting resistor serially connected to the light string.

9. The decorative light system according to claim 6 , wherein the bulb comprises at least a first LED in a first color and at least a second LED in a second color.

10. A method of changing the color of light emitted from bulbs on a light string system comprising a plug, the light bulbs comprising at least two LED chips, wherein at least one LED chip is connected in parallel and at least one LED chip is connected in reverse parallel and an adapter comprising a rectifier placed between one side of an adapter plug and a corresponding side of the adapter outlet, said method comprising:

connecting the adapter to a power means;

connecting the plug of the light string into the adapter outlet, wherein when the plug of the light string is in a first orientation, the rectifier is connected allowing passage of a positive half-rectified wave that is passed through the light string lighting half of the LEDs connected in parallel in a first color; and

reversing the plug of the light string to the second orientation, wherein the rectifier is connected allowing passage of a half-rectified wave that is passed through the light string thereby lighting half of the LEDs connected in reverse parallel in a second color, wherein the plug of the light string is plugged into the adapter at orientations to adjust current flow.

11. The method of claim 10 , wherein the light string is directly connected to the power means.

12. The method of claim 11 , wherein the first color is white and the second color is red such the combined color is that of a pink or pastel appearance.

13. The method of claim 10 , further comprising changing the color of light by unplugging the plug of the light string from the adapter, turning the plug of the light string by 180 degrees, plugging the plug back into the adapter, with each blade of the plug placed in an outlet hole opposite the outlet hole that the blade of the plug was in originally.

14. The method of claim 10 , further comprising adjusting an overlap time of the LEDs.
