What is the difference between fluorescent film and luminous film?


Fluorescence: Fluorescence is by ultraviolet laser beam irradiation, the object surface will emit a dim light with a color. The fluorescent light source is generated by external irradiation, and the fluorescent material does not have the ability of self-luminescence.
Glow-in-the-dark: glow-in-the-dark materials are those that emit subtle self-emitting light when no light is illuminated, without the need for external energy. It glows in the dark.

1. Different principles
 
The principle of fluorescence film is that under the excitation of light source, the fluorescence color is visible, and after removing the light source, the fluorescence is not visible; The principle of luminous film is that after the light source is excited, the light source is removed, and it can glow for a long time. The luminous time is determined by the amount of luminous powder and the nature of luminous powder. There are long-term (long specific afterglow) and short-effect (short luminous time) points, and the light storage time is better.
 
2. Different uses
 
Fluorescent film is more conspicuous, often used during the day; Glow-in-the-dark film is often used in evacuation tunnels and underground working areas.
 
Luminous characteristics:
 
1, short light storage time, high brightness, long afterglow time, rich color varieties.
 
2, extremely stable physical and chemical properties, strong environmental adaptability and extremely long service life.
 
3, non-toxic and harmless no radiation, no combustion, no explosion, no other harmful heavy metal elements or chemicals.
 
4, small particle size, uniform particle size distribution, easy production and processing.
 
5, products made of this material have established a number of independent intellectual property protection systems.
 
6, luminous powder after color film treatment, weak effect in strong acid and alkali environment, and suitable for use in water-based coatings.
 
7, excitation conditions sunlight, general lighting lights, environmental stray light can be used as excitation light source.
 
8, luminous time a light absorption can glow for more than 8 hours
