mining lamp ,miner lamp,led headlamp,led headlight mining lamp miner lamp led headlight mining lamp Certificate: 1.Quality Management System Certificate No:GB/T19001-2000 idt ISO9001:2000 2..Explosion-proof Certification Of Compliance No.KD06250,KD06251 Main technical parameters: No Item Unit Data 1 Rated capacity Ah 4 2 Nominal voltage V 3.7 3 Lighting time h ≥15 4 LEDlight source Rated voltage V 4.2 Main light source/power mA 300 Auxiliary light source mA 110 5 Max illuminance at 1m Begin lighting Lx 4500 Lighting 11h Lx 4000 6 Weight g 450 7 Nos of battery cycle times ≥500 8 Carton packing roll/CNT 20 9 Packing size cm 36*36*44 Usage: It is suitable for mineral industry,tunnel projects,construction and maintenance for power, communication,highway,railway at night,night lamp for cutting off rubber plant and absorbing mucus and for lighting a flood,rescuing and marine use. Features:Lost cost ,high safety. 1. LED : less energy and super brightness LED 2. Battery : safety lithium ion battery 3. Small in size, light in weight, free maintenance, explosion prevention, waterproof, long life 4. Lighting time : more than 15 working hours, double light source design 5. Charger AC input : AC110 240V, 50/60Hz DC output : DC4.2V,1A 6. Working temperature : -10 45 degrees 7. Relative air humidity : <= 95% +- 3RH Technical specification: 1.Battery (Lithium ion)It adpot new styled lithium ion battery which is with over-charging , over-discharging and a short circuit protection fuction.Every battery cycled lifetime is more than 500 times.It has 75% rated capacity after using 500 times.Its a newest environmental protection battery. 2.LED:it adpot 1W high-power Led,The life is more than 50000 hours.illumiance is more than 3000 lux/60lm,it adpot two sets of light source,one is main - six auxiliary light source or main-axiliary in one .when main light source lose function,pls turn a switch axis into auxiliary light source then it go into work normally(This is for meet an emergency) 3. Charger(Lithium ion): It adpot isopiestic pressure current limiting charging way.Its setting value volatge is 4.2V(normal charging voltage is 4.2V).When charging max current is 1A and voltage approachs to 4.2V,charging current will reduce gently.When batterys voltage is 4.2V and current is less than 100A,the indicator light will display green color.this mean that miners lamp can be used normally.When its charging ,the indicator light will display red color.
