Abstract

A Christmas/Decorative light without wires. This is a solar rechargeable indoor/outdoor Christmas/Decorative light that is characterized by a bright long lasting LED and long lasting energy source. The rechargeable energy storage device is electrically coupled to a flexible solar array that powers the light. The light assembly is constructed with a small, flexible solar array that allows it to be used on a variety of light sizes including mini-light, C6, C7, and C9 bulb. The LED holder has a nearly unbreakable lens for illumination and allows for varying colors. The solar array is mounted on the casing and is maximized to collect the ambient/solar energy during the daylight hours. The light assembly is designed with a clip that allows it to be attached/mounted to a variety of indoor and outdoor structures including Christmas Trees and houses.

Claims

1. A solar powered light, comprising:

a conical casing,

a light emitting diode,

a micro battery,

a clip attached to the casing,

a solar cell, wherein the solar cell is a flexible solar cell wrapped forming the conical casing and recharge the micro battery that provides power to the light emitting diode,

a printed circuit board disposed within the casing and electrically connected to the solar array, and

a light sensor on the casing for automatically turning the light emitting diode on during time of low light and off during the day.

3. The solar powered light of claim 1 wherein the light emitting diode is monochromatic.

4. The solar powered light of claim 1 wherein a lens encapsulates the light emitting diode within an end of the casing.

5. The solar powered light of claim 1 having an on/off switch that disconnects the light emitting diode from the micro battery.

6. The solar powered light of claim 1 wherein the printed circuit board includes circuitry to control the rate of discharge of the energy storage device.

16. The solar powered light of claim 1 wherein the casing has a height and the solar array has a height, wherein the casing height is no greater than the solar array height.

2. The solar powered light of claim l wherein electrical connections between the solar cell, micro battery and the light emitting diode are within the casing.

7. The solar powered light of claim l wherein the printed circuit board includes circuitry to control the rate of charge of the micro battery by the solar cell.

8. A string of solar powered lights comprising:

a plurality of lights, each light including a casino, a light emitting diode extending from the casing, an energy storage device secured within the casing, a printed circuit board operatively connected to the diode, a casing, wherein the casing is a conically wrapped flexible solar cell which recharges the energy storage device that provides power to the light emitting diode, and a light sensor on the casing to automatically control power discharge of the light; and

a connecting medium for connecting the plurality of lights to one another.

9. The string of solar powered lights of claim 8 wherein the connecting medium is a string.

10. The string of solar powered lights of claim 8 wherein the connecting medium is a wire.

11. The solar powered light of claim 8 wherein a lens covers each light. emitting diode at an end of the casing.

12. The solar powered light of claim 11 wherein a uniform color of lens is used.

13. The solar powered light of claim 11 wherein a variety of colored lenses are used.

14. The solar powered light of claim 8 wherein at least one light produces a single color of light.

15. The solar powered light of claim 8 wherein at least one light produces a white light.
