ABSTRACT:
A light stick is formed from an elongated, light-transmitting member having a plurality of grooves formed in its exterior surface and an aperture at one end for receiving a light source, such as a light-emitting diode (LED). The light from the LED is directed into the interior of the elongated member. The grooves or other recesses, reflect the light traveling along the length of the elongated member, radiating the light outwardly to enhance the brightness of the light emitted from the exterior surface along the longitudinal axis of the elongated member.
