Safety: in sealed design of the whole product,short-circuit protection and anti-static housing make the product has very good function of explosion-proof.
Reliability: The high strength housing, optimized structure design, the perfect of protection for Li-ion battery over charge/discharge design strengthen the reliability of the lamp.The miner's lamp is very sutibale to work under bad environment of the coal mine.
Portability: Small in size, light in weight, portable to carry, free of maintenance of the Li-ion battery, simple charging, easy usage.The miner's lamp has received many praises from the miners.
Efficiency: the maximum lighting degree reaches 2800Lux, work time last to 15h, usage life 1000 cycles (in reasonable working condition).
Environmental Friendliness: the miner's lamp is made from environmental Li-ion battery and other environmental materials.So the miner's lamp is an very good green product.
Economy: duration of usage three times longer than lead and acid miner's lamp, plus Li-ion battery is free maintenance then save in maintenance fee make the product higher economy benefit. Much more better than the traditional miner's lamp.
Safety Lamp User Guide:
1. There's no need for initial charging for high power Li-ion battery miner's lamp, it can be used immediately after daily charging.
2. Stable current stable voltage charging, the charging current is 1000mA ±100mA, voltage is 4.2V ±0.05V, charging time is about 8-12 hours. The circuit designed with perfect watching and controlling system, able to automatically watch and control charging process. At the beginning of charging it is stable current charging at 1000mA ±100mA, the charger indicator is red color. When charging voltage reaching 4.2V, automatically turn to stable voltage charging, at this moment the battery is charged about 70%, at this moment, the charger indicator start turn into orange color and current is reduced step by step. when the battery is charged enough it automatically powered off to stop charging and charger indicator display as green color. (note: you can charge at any time, no need to wait to charge after use up the power, bring forward charging is better for prolonging the life span of the battery).
1. In case of short-circuit, the protection circuit will cut off the
power at an instant. After the problem of short-circuit is solved,
re-switching on of the lamp would restore the usage.
2. The miner's lamp can't be used or stored in a environment of over
60ºC and should be stored in a low-temperature and dry environment.
When long-term storage is needed, charging should be done half year,
50% charging capacity should be reached each time.
at the meantime miner's lamp also call Miners Lamps, Mining Lamps, safety lamps, etc
