Abstract

A light emitting device (1), which is adapted to be attached to at least one air cylinder (2, 3) that is to be carried by a diver, such as a scuba diver or a smoke diver, comprises an electroluminescent filament and a protective cover enclosing the filament and made of translucent, heat resistant silicone material. The light emitting device (1) further comprises resilient fastening elements (4a, 4b), which are arranged to secure the light emitting device (1) to the air cylinder/cylinders (2, 3) by a force determined by the resilient properties of the fastening elements.

Claims

1. A light emitting device, which is attached to a set of air cylinders that is carried by a diver, such as a scuba diver or a smoke diver, the set of air cylinders having two parallel air cylinders, the light emitting device comprising an electroluminescent filament and a protective cover enclosing the filament and made of translucent, heat resistant silicone material, the light emitting device further comprising resilient fastening elements, which secure the light emitting device to the cylinders by a force determined by the resilient properties of the fastening elements,

the light emitting device having the shape of a U, whose one leg is releasably fastened to one of the air cylinders by at least a first resilient fastening element and whose other leg is releasably fastened to the other air cylinder by at least a second resilient fastening element.

2. A light emitting device as claimed in claim 1, in which the filament with the protective cover is placed in a groove in a stainless steel support rail extending along the protective cover.

3. A light emitting device as claimed in claim 1, in which the filament is connected to a battery-operated power source in the form of a DC/AC converter, which is also enclosed by the protective cover.
