Mine with KJ4LM nickel hydrogen miner, lithium miner 

 I. Scope of application: 
 KJ4LM (A) the individual wearing the use of coal mine workers dedicated lighting. The miner's lamp of this type of nickel-metal hydride battery pack for power supply, install dual light source for the LED bulb holder, the overall structure of the delicate and exquisite, light weight, battery maintenance-free LED light source life, my company to design a new generation of products. 

 Second, the product structure characteristics: 
 KJ series of cold light miner with at the national patent miner special safe polymer lithium-ion battery power, high power LED light source, precision high-tech manufacturing miner IC to protect the device design, the appearance of the light volume small, light weight, large capacity, a long time to light lamps, the light shines high penetrating ability, easy to use maintenance-free, long life, non-polluting. Automatically shipped reality. 
 An energy-saving performance: The main light source with a super-highlight high-power 1WLED secondary light source 6 low-power LED, low power consumption, high luminous efficiency, power consumption is only 20% of the incandescent lamp of the same luminous flux, breaking the traditional tungsten the mercerizing efficiency of low-defect, with the energy efficient features. 
 (2) environmental performance: white LED light and soft, no glare, operations staff does not cause eye visual fatigue, improve work efficiency. 
 (3) Working time: light continuous working time of up to 12 hours, you can meet the duty needs, but also as 
 Blackout emergency lighting; charging time of only 8 hours once fully charged, can be used at any time in six months. 
 Intelligent protection: light with a put, and short circuit protection device, effectively protect the battery and extend fixtures 
 Life; smart charger with short circuit protection and charging display device. 
 5 Durable performance: use of optimized structural design and special engineering plastics to ensure the product can withstand strong 
 Collision and impact (in the case of accidentally dropping or collision force can normally use), and easy to use, strong 
 Light, helmet wear three ways, according to the need to select the handheld hip, and any conversion. 
 6. Reliable and practical: specially designed lithium battery pack has no memory, no pollution, safe and stable performance, low self discharge rate, 
 On a single charge light can work continuously for about 12 hours. 

 The miner's lamp for portable cable superstructure will be part of the lamp and battery part even as the overall miner's lamp, the lamp can be fixed on the miner. KJ4LM (A)-type lamp designed with a main light source LED 180 MA, LED auxiliary light source. Clockwise rotary switch knob to the main light source is lit, the counterclockwise rotation of the switch knob auxiliary light is lit. The miner's lamp battery shell design has a closed structure of the wear ring, easy to wear. The lamp design of the charging device, and charging rack supporting, charging convenient and reliable. Ni-MH miner require specialized charger for charging in the charging process to determine whether the battery is full.
