Chemical glow stick

The invention relates to an emergency lighting device with a chemiluminescent light stick, one connected to it manual operating device for operating the light stick and a container for storage or the visible holder of the light stick.

It is known to use chemiluminescent glow sticks in emergency situations to use. Various glow sticks have been described for these uses. One such chemiluminescent Light stick essentially comprises a flexible translucent or transparent outer tube, which contains several chemical components for a chemiluminescent mixture, which in the outer tube by fragile Separating devices are separated from each other. If the fragile separators are broken, get the components inside the outer tube in contact with each other and they react to generate chemical Light. Typically, such a light stick comprises a flexible outer tube made of polyethylene which is attached at both ends is sealed, as well as one or two inner glass vials or glass ampoules, each of which is a separate component for the chemiluminescent mixture contains. As long as the vials or vials are intact, the components will kept separated from one another within the outer tube. They are practically inert and do not produce any light. But when the violas or ampoules housed inside the outer tube were broken by the action on the flexible outer tube are, the components get mixed with one another within the outer tube and the mixture of the reactants leads to the emission of chemiluminescent light. This reaction generates light without the simultaneous formation of Heat, flames, sparks, gases. This means that such a light stick can be used safely for lighting in an explosive environment

use. There is no danger of causing a fire or of the operator being burned. The reaction takes place exclusively inside the outer tube, so that the light also comes into contact with the light stick is not extinguished with water. This means that the light stick can even be used underwater. Certain glow sticks emit light of considerable intensity for several hours after being activated. They are therefore suitable for marking purposes during night rescue operations.

According to the invention, a light stick is housed in a container, which on the one hand serves for the easily accessible storage of the light stick and on the other hand especially the light one and convenient use of the light stick in various emergency situations.

A preferred glow stick for the present invention comprises two reactive components of the chemiluminescent Mixture in separate glass ampoules inside the outer tube. There is a reactive oxalate ester in one of the ampoules housed and in the other a reactive peroxy compound. These two components would when in contact with Air are subject to gradual decomposition. The air could penetrate through the outer polyolefin tube. However, it can do not get through the glass ampoules. Thus, a light stick of this type has a long life without the The light stick must be housed in a hermetic envelope during storage. In preferred embodiments With two inner glass ampoules, a third separate liquid component can be provided, which exclusively consists of non-air-sensitive components such as solvents, Fluorescent substances or the like.
