KLJ4LM(A) is a new type of miner's lamp. It based on the power supply which is Li-ion storage battery, and its lamp-house is LED semiconductor illuminance.1) Product Specialty:1. Power supply is Li-ion battery closed power. It has the characteristics of maintenance-free, high-energy, longevity of service, light-weight, no leakage, environmental protection and safe.2.. Used two different lightness’ LED lighting inside the lamp. It could switch by the switch, and the subsidiary lighting can continue to use for more than 15 hours.3. The new type of miner’s lamp is maintenance-free in using life.4. Good color-rendering properties of light source and penetrability specialized in dust or fog environment.5. Humanity and green environmental protection: its weight is only sixth of lead 2 acid miner’s lamp----about 500 gram. It is portable and easy use. No leakage, no empoison.portability: head lamp and battery is separate,the head is very light,6.Economy:three times longer than lead and acid cap lamp and saving in maintenance makes the product more compatible in price7.wate resistant:1m.2) Main use The product is portable. It can use in the mine where full of admixture of firedamp.3 Magior technical specifications: Features                   KL4LM specificationsRated capability                4.5Ah(li-ion battery)Rated voltage                  3.6VContinuous discharging  time     >15hMain ligh LED working votage    3.2VMain light LED working Current   0.25AMain light power                1WMain light Luminous flux         >40LMLamp lighting degree (after 11 >500Lux(distance in 1 meter)Hours working time)Main light Usage life hour         >30000hAccessory light Usage life hour     100000hShort circuit protect time          <15msUsage duration of battery          500recharges(in reasonable working condition)(recharges)Charging time                  <8hours4 operation procedure5Charging:   Manufacturer provide charger to user,please use it onlyWhen long-term storage is needed,charging should be done within two months              1) 新型矿灯采用了镍氢密闭蓄电池作为电源，具有免维护、能量高、寿命长、重量轻、无液漏、无污染、安全可靠等性能。2) 采用了新型的LED半导体照明作为光源，做到不发热，能耗小，发光效率高，寿命长（达到2万小时以上），安全可靠。3) 灯头内采用了不同亮度的双LED的光源 (一个1W. 大功率LED和一个?10 LED), 可以通过开关转换使用, 副光源照明时间可达35小时。4) 新型矿灯在使用寿命周期内不需要进行维护，真正做到了免维护。5) 新型矿灯显色性好,穿透能力强。在煤矿井下照射的面积显色性好，粉尘、浓雾环境中穿透性很强，能见度高。6) 矿灯电源电路加装矿灯短路保护器，动作灵敏可靠，当矿灯发生短路时，能在15ms内切断矿灯电源，保证了使用安全。7) 更具人性化、绿色环保：产品重量仅为铅酸矿灯的六分之一,重量仅为500克,大大减轻了煤矿工人的负载.矿工携带方便，使用灵活无漏液，无污染。8)包装: 1个矿灯装一个包装盒, 盒子尺寸:135*100*120 mm
