Abstract

A solar light stick for use as a lawn or garden novelty. The solar light stick has a support member, a solar panel, a rechargeable battery, an LED, and a wand. The wand contains a light transmissive material that may be transparent or translucent. The solar panel charges the rechargeable battery which, in turn, provides power to the LED. The LED is positioned to provide light to the interior of the wand. As such, the LED may be located within a recess in the wand. Voids, such as interior bubbles, suspended objects, or surface irregularities may help to disperse light from the LED in a direction external to the wand.

Claims (23)

1. A solar light stick for use as a lawn novelty, comprising:

(a) a support member, the support member having an upper end and a lower end, the support member comprising a tube;

(b) a housing at the upper end of the support member;

(c) a solar panel connected to the housing such that the solar panel may be exposed to ambient light;

(d) a rechargeable battery within the housing and in electrical communication with the solar panel;

(e) an LED connected to the rechargeable battery;

(f) a wand, the wand having a proximal end and a distal end, the wand comprising a rigid, clear plastic and having a smooth, cylindrical surface, the wand having a recess at its proximal end, the LED being located within the recess at the proximal end of the wand, the wand containing interior bubbles to disperse the light from the LED;

(g) an ambient light sensor within the housing; and

(h) an on-off switch within the housing and in electrical communication with the LED.

2. A light stick for use as a lawn novelty, comprising:

(a) a support member;

(b) a solar panel connected to the support member;

(c) a rechargeable battery connected to the solar panel;

(d) a light source connected to the rechargeable battery, the light source emitting light; and

(e) a wand, the wand comprising a light transmissive material, the wand having an interior and an exterior, the wand being located adjacent the light source such that the light emitted from the light source provides light to the interior of the wand, the wand containing interior bubbles to disperse the light from the light source.

3. A method of using a lighted ornament, comprising the steps of:

(a) providing a lighted ornament having

1. a solar power generator;

2. an LED connected to the solar power generator; and

3. a wand, the wand comprising a light transmissive material, the wand having an interior and an exterior, the wand being located adjacent the LED such that the light emitted from the LED provides light to the interior of the wand, the provided wand containing bubbles to disperse the light emitted from the LED;

(b) locating the lighted ornament by selecting a location where the solar power generator will receive ambient light;

(c) providing electrical power to the LED via the solar power generator; and

(d) illuminating the LED as a result of the provided electrical power.
