Patent Images
1. A liquid-activated lighted artificial ice cube, comprising:
- a hollow body;
a pair of electrodes exposed on the exterior of said hollow body;
a printed circuit board disposed within said hollow body, said circuit board having mounted thereon an LED, an integrated circuit in die form, and a transistor; and
a battery disposed in the lower half of said hollow body below said printed circuit board, said battery being connected to said LED, said integrated circuit, said transistor and said electrodes;
wherein said electrodes are located at the bottom of said hollow body;
wherein said LED is located in the upper half of said hollow body; and
wherein said hollow body includes a bottom wall having at least one lower standoff extending upwardly therefrom and includes a top wall having at least one upper standoff extending downwardly therefrom, said circuit board being sandwiched between said lower and upper standoffs.

Abstract
A liquid-activated lighted ice cube includes a battery-powered electrical circuit and LED housed in a hollow body that resembles an ice cube. The circuit includes electrodes exposed to the exterior of the hollow body that, when in contact with water or other liquid beverage, cause the circuit to turn on the LED and illuminate the beverage.
