The light-emitting film can absorb light in the light environment and light in the no light environment, commonly used with fire, lighting.
A light-emitting film which absorbs light energy in a light-emitting environment and emits light in a matte environment, and has a soft, light-colored base layer provided with a light-emitting layer having light-transmitting properties, Layer with a layer of transparent outer membrane layer, the back of the bottom with a sticker layer, stickers attached to the detachment of paper, the utility model using polymer materials as a substrate by a special process from the processing of the film The invention has the advantages of high luminous brightness, high luminous time and excellent weather resistance. The product is non-toxic and has no radiation. The utility model is mainly applied to low emergency lighting, fire safety sign and general guidance and identification.
The principle of luminescence of the luminescent film: the alkaline earth aluminate activated by rare earth elements, the molecules of the silicate material or the electrons at the periphery of the atom are excited from the ground state to the excited state by external energy such as heat, light and ray, and are in an unstable state The Still excited after the outside world to return to ground state, the excited state of the electronic by the environmental heat and gradually release the light.
Another explanation of the principle of light-emitting film luminescence: is a microscopic physical process. As the outer layer of rare earth material structure of the outer electrons in the case of light from the low energy level transition to high energy level, and fall into the structure of electronic traps and storage, in the dark electrons can be restored from the high energy level to low energy level characteristics, and thus light The
