Abstract

An LED illuminated glow stick apparatus uses multicolored LEDs to illuminate an optically transmitting tube that is encased in a soft cushion that is at least partially transparent. The LED illuminated glow stick is capable of glowing in a variety of different colors. It is reusable and rechargeable and safe for children. The LED illuminated glow stick is useful as safety equipment and as a toy. The LED illuminated glow stick may additionally include an LED flashlight.

Claims

1. An LED illuminated glow stick apparatus, comprising:

at least one multicolored LED;

an optically transmitting tube in proximity to said multicolored LED that illuminates when said multicolored LED is illuminated;

a control circuit for controlling said at least one multicolored LED to be illuminated; and

a soft cushion that encases the optically transmitting tube, said soft cushion being at least partially transparent.
