Abstract
The invention reveals a chemiluminescent lighting element which consists of two concentric, long tubes each of which is made of a translucent and preferably flexible, synthetic material, one of which contains a first chemical liquid which emits chemiluminescent light, and the other of which contains a second chemical liquid whose function is to cause the light activation of the first liquid. The internal tube is provided with an element which moves essentially along the entire length of said tube, by a pressure imparted to it through the wall of the external tube. The sliding element is provided with a blade, which cuts the internal tube longitudinally as the element progresses along the tube and thus causes the liquid in each tube to mix whereby the first liquid is activated and chemiluminescent light is produced.
