Night cap LJ-1001 
 I. Overview 
 LJ-1001 is a night cap wolf Jie Optoelectronics, Shenzhen Development Co., Ltd. newly developed coal and building site safety, explosion-proof LED lamps headset cap, the indicators in full compliance with GB2812 "helmet test methods" and GB7957 -2003 "General requirements for safety miner's lamp," national standards and industry standards, mainly applied in the coal mine and construction sites and other activities needed to carry lighting applications. The night cap for the integrated structure, all of the light source and the battery installed in the cap body, good looks, compact, shock, vibration, heat changes, sealing, waterproofing, the use of portable, won the national patents (Patent No.: 200930327609X and 2009203163433). Selection of high quality imported light source semiconductor LED as a light source, low power consumption, low heat, energy efficient, long life. Battery using the most advanced JHW safety explosion-proof lithium iron phosphate battery maintenance free, long life and charge cycles is not less than 800 times. 
 Second, characteristics 
 Night cap LJ-1001 light source with high quality imported semiconductor LED as a light source, luminous flux, long life, stable and reliable. The main light source and the auxiliary light source with dual illumination in the form of a light damage to another can be used normally to ensure the safe use under any conditions. 
 Battery charging circuit using the most advanced lithium iron phosphate protection of high-precision special charge management integrated circuits and integrated circuits, charge by pre-charge - constant current - constant - and then charging, can effectively protect cells, but also to ensure that the battery capacity fully utilized to maximize the high-capacity lithium iron phosphate properties. Portable charger with external power supply, quick charging time, the red / green color LED charging status indicator has two kinds: the red charging light; fully charged the green light. 
 Optimized structure design and high-strength engineering plastic shell, high mechanical strength, with strong anti-collision and impact properties. 
 Special sealing process and optimization of surface treatment technology, the lamps waterproof, dustproof, corrosion, to ensure that lighting in a variety of reliable operation in harsh environments.
