Application
Can be used as portable lighting fixture under gaseous mine and normal mine; also can be used as portable lighting fixture in other environments.
Features
Portable and durable: small volume, light in weight, first discharging time can reach up to 20 hours, maintenance free and low cost.
Constant lighting and uniform illuminance: main and auxiliary lamp source adopt power supply mode of consistent current boosting, which ensures service life of both lamp source and allows uniform illuminance.
One main and seven auxiliaries: when spare lights work, working light of main lamp also exist with illuminance achieving up to 130Lx.
Fast charging, safe and reliable: charging voltage and current of high integration control the circuit, PWM pulse width modulate mode, advantage in large current charging without heating and enables full charging in 6-8 hours.
Very long service life: it uses lithium battery which has long life and high level of safety, also, it will not lead to explosion when overcharged and overdischarged in 5-10 times rated voltage and harsh crash, etc. It is able to withstand high temperature e (300C-500C), LED life can reach up to 50,000 hours without need to replace, which is green and environmental friendly.
Easy operation: easy and reliable operation, and long service life.
Short circuit can resume: this product has resume function, when it is short circuit, mine light fitting can resolve charging by itself without taking any charging measures.
