Chemical lightstick generate light by the reaction of chemical

species . The best example of chemiluminescence in nature is

FIREFLY. Generally, the mechanism of chemiluminescence is

to transform the energy generated by the chemical reaction into

light energy instead of thermal energy. So the lightstick will not

burn or spark . In some occassions, such as, mine channel ,

confined space with burnable gas or room with the possibility of

gas leakage, using lightstick as illumination source is the only

safe alternative.

With the progress in chemical light technology in recent years ,

the duration time can last for hours long. Plus its small volume

and light weight, it can be applied in more and more fields.

Normal lightstick have double containers structure. The outer

container is made of plastics while the inner container is made

of glass. The glass ampoule contains solution A. Solution

B exists between the ampoule and plastics container. When

bending the lightstick, the glass ampoule breaks at the

same time. The two solution mix and chemical reaction occurs

and generate light.

Because of the air-tight sealing of the outer plastics container ,

the chemicals within the lightstick will not leak out. This way

make the lightstick can work at any weather condition.

Even under the deep sea, the lightstick can perform as usual .

Undoubtedly, with so many outstanding advantages,

the lightstick will play a unprecedentedly important role in the

field of illumination.
