Explosion-proof flashlights are used to provide mobile lighting in fire protection, power, industrial and mining enterprises and other flammable and explosive places. Geological exploration, tourism exploration, border defense patrol, sea defense patrol, rescue and disaster relief, field operations, tunnel operations, forest fire prevention, airport inspections, railway inspections, archeological and fire command, criminal investigation, traffic accident handling, power repair and other lighting needs.
Buy three major considerations:
1, close lighting (less than 1 meter, with the surrounding objects reflective)
Recommended multi-LED products, suitable for camping lights, headlights, etc. in close writing, repairs, meals, etc., but do not advocate the more the better the lamp, LED operating voltage is about 3V, so many flashlights, headlights are used 3AAA battery To promote, 20 to 30 lamp heads are close to the current load limit, and more likely to damage the battery, reduce the lighting time, the brightness is not obvious increase, personally think that more than 5 is enough, the extra LED will only increase The probability of failure.
2, in the distance (2 meters to 50 meters)
High-power LED products, especially 3W products, 3W chip is also recognized as the most mature product of the Lumens, buy a brightness of about 80 lumens, lower battery consumption, especially for night travel. If you use a good product, the spotlight can be done very well. Its use time can be calculated simply by the electronic knowledge that everyone has mastered in junior high school. For example, it is driven by a 3.6V2000ma battery. The operating current is about 1A, which is approximately 3W of power running, so that it can have two hours of use time, and actually On the other hand, the current will drop significantly with voltage drop, and the decrease in brightness will not be so obvious. This is a major advantage of LED. Unless the driver circuit is used at full power, the actual use time is much longer than the calculated value to the above 1000mA battery. For example, the actual use time may be greater than 4 hours.
3, long-range, large-scale search (more than 100 meters)
There is no emery Mogan that porcelain work, in order to go far, a huge lamp cup is indispensable, while high-power light bulbs also require a headlight cup to adapt, plus a larger backup battery supply, so these super East The East can not accommodate in the pocket, more suitable for search and rescue teams, firefighters, etc., personal use is not very convenient.
