1.Product Features
KL2.5LM(A) is designed based on GB7957-2003,< General requirements for safety of cap lamp >, the lights have advantage of small, light, convenient to carry, long using life, high lighting, maintenance-free, safe and less wasting, charging fast, safe and less wasting, etc. As the main light source damage or lighting time outstrip the provision, use another LED auxiliary light source to provide the workers for faint light in well, at the same time, it plays a life-saving role when happened special circumstance. The auxiliary power source can provide more than 60 hours.
This light have lithium battery inside, set a protecting circuit for over-charge, over-discharge, over-heat, extending the battery's using life. The battery inside of the lamp, so the structure to dexterous, convenient to carry, improve work efficiency.
2.Structure and Principle
KL2.5LM(A) is consisted of lamp holder, cable, batteries ( including safety protection device for lithium batteries ).There is LED light source in lamp holder, and fixed on the mining head lamp.
Basic circuit of KL2.5LM(A) is made of light source, lamp holder, LED luminous diode, switch etc, the lamp holder has circuit switch, control main light or auxiliary
Light to shine or put out. The lamp holder have charging device, adopt lamp holder charge ways, there are short circuit protection device in lithium batteries, can cut off the power automatic and protect safety once the short-circuited phenomenon happened.
3.Usage and Operating Environment
Mining light can continuous discharge or intermittent discharge, use maintenance-free of lithium batteries can use directly under generally. To use after charging as long time shortage or for insurance purpose. Can charge by traditional 5v charging rack for mining lamp, stop charging automatic after charging no more than 8 hours.
There are two directions in lamp holder switch. One is main source, to work. Another is auxiliary light source, to spare or non-working. The lamp holder have automatic outage device, can cut off charging for the bulb when glass or bulb broken, avoid blasting through flammable gas.
4.Environment and Condition
a)Environment temperature:-5℃~+40℃
b)Air relative humidity (RH): < 95%(25℃)
