Abstract

A device for providing chemiluminescent light from a chemical reaction of suitable compounds in the presence of a fluorescent compound, the device being a self-contained buoyant light unit.

Claims

1. A light marker device adapted to float on a liquid surface comprising a weighted buoyant float and a tubular member containing chemical means for producing light, the tubular member having an extension, the said float having a socket-like receptacle therein with a provision thereon adapted for receiving and removably engaging the tubular chemical light producing means, the tubular member extension having an opening to engage the protrusion in the socket-like receptacle of the float.

2. The device of claim 1 where the float has means for varying the buoyancy through the addition or removal of a ballast material.

3. A light marker device as in claim 1, said tubular member comprising a tubular chemiluminescent light stick, said light stick comprising an outer flexible, light transmitting means and an inner rigid, breakable tube means, substantially coextensive with said outer tube means, a chemiluminescent component in each said tube means, means to close said tube ends, and means to maintain said inner tube means relatively fixed with respect to said outer tube means.

4. The device of claim 3 comprising a pair of concentric tubes.

5. The device of claim 3 wherein said inner tube means comprises more than one tube.

6. The device of claim 3 wherein said buoyant member comprises a reflective material adjacent said light stick.
