For the mine lamp, is the more function the better? 

For the mine lamp, is the more function the better, is the lighter the better? 

About the mine lamp, most of us know, then the mine lamp is the coal miners underground must be equipped with lighting tools, is a special explosion-proof products. As the core components of mine lamp, the power source and light source of mine lamp are related to the safety of mine production and the life safety of miners. Therefore, the mine lamp needs to fully understand the performance of the battery, in order to do a good job in the mine lamp management and battery maintenance.

At present, there are many kinds of mine lamps produced in China. The commonly used domestic new mine lamps are KS -- 6, KS -- 7, KS -- 8, (A), (B), (E), (P), (M) and other types of lead acid battery lamp and KJ -- 12, 2TN -- 10 type alkaline battery lamp. In addition, there are KSW12H type lead acid methane alarm lamp, roadway lamp, Explosion-proof headlights, etc. Alkaline battery mine lamp is divided into nickel battery mine lamp, iron and nickel battery mine lamp and lithium mine lamp because of the different material of negative electrode. Its products are KJ - 12, 2TN - 10 type and so on. 

Alkaline battery mining lamp has the performance of acid battery mining lamp in addition to the volume quality has his unique. Some alkaline mining lamp shell using nylon material, monomer to one combined type, compared with the same capacity of lead-acid battery weight 85% lighter, 60% smaller volume. Another feature is long life. For example, the mass of Julongji nickel KJ -- 12 (B) type mine lamp is only 0.9kg, the capacity can reach 16A.h, up to 2200(kos) at the beginning, 11 hours after up to 900 (kos), its circuit uses the microelectronic chip composed of safety circuit, the service life is 2 times higher than the same capacity lead-acid battery, cycle life 88 times. 

Although the structure of the dragon type alkaline mining lamp is simple, but the use of monofilaments bulb, bulb no switch, is its weakness. More important is to use constant current charging, electrolyte consumption is large, and need to open the cover to charge. 

Alkaline mining lamp voltage is 2.5 volts, bulb current is 1 ampere light flux 22 (lumen), but the rated capacity is different, the lamp time is different.
