Abstract: An illumination device for mounting inside a balloon comprises a light source, such as LED, and a battery power source for the light source, both mounted in a housing. The housing is provided as an inner part of a first plastics material in which the battery power source is housed and an outer casing of a second plastics material, which at least partially surrounds the inner part and provides a cover for the light source. The second plastics material is transparent and resiliently deformable and may be a thermoplastics elastomer. In preferred embodiments the housing is provided as a one-piece unit which is a co-molding of the first plastics material and the second plastics material, and which is provided as two mating sections hingedly connected to each other.

Abstract: In respect of a balloon (10) having an illumination device (20), including a light emitting member, which is mounted onto the wall inside the balloon cavity, at least one sheet (22, 24) of flexible material is connected to the illumination device inside the balloon cavity to serve as a parachute for the illumination device (20) in the event of rupture of the wall of the balloon when in an inflated condition. In embodiments where the illumination device is provided with a projection (12) and is mounted to the wall of the balloon by an attachment element, such as elastic band (18), engaging said projection from outside the balloon, the or each sheet of flexible material (22, 24) serving as the parachute may be connected to the illumination device (20) and to the balloon wall by location over the projection (12) and engagement by the same attachment member.
