Abstract:
A balloon illumination system, for use with a thin film balloon having a pair of film panels sealed together to form a balloon interior, balloon top and a balloon bottom, a mouth near the balloon bottom, an apex at the balloon top, and a flat film valve defining a sleeve which provides gaseous communication between the mouth and the balloon interior, comprising:a tube having a proximal end and a distal end, the tube sealed at the distal end, the tube sized to fit tightly within the sleeve yet allow said tube to pass therethrough, the tube having a length between its proximal and distal ends such that the tube extends substantially from the mouth to the apex when fully inserted into the balloon through the valve; a light source located within the tube between the proximal end and distal end, the light source located substantially midway between the proximal end and distal end; an electrical cable extending from the light source proximally through the tube, exiting said tube at the distal end thereof; and a power source, connected to the electrical cable for selectively illuminating the light source.
