LED Light Unit Li-ion battery miner's Lamp NEW (2008-6)

LED miner's lamp (LED cap lamp, LED safety lamp) NEW (2008-6)
The innovatively designed KL5M LED Li-ion Cap Lamp combines the latest lighting and battery technologies to result in a brighter and lighter cap lamp. Using lithium-ion technology in conjunction with a purpose designed LED the cap lamp is designed in accordance with the Restriction of Hazardous Substances Directive (RoHS). The KL5M is not only much smaller and ergonomically designed for wearer more comfortable than the traditional lead acid cap lamp, and they are one third of the weight at only 0.6kg. The use of lithium-ion technology also removes numerous hazards associated with the use of lead acid style batteries. Unlike traditional lead acid batteries, lithium-ion contains no dangerous chemicals or heavy metals and requires no maintenance such as topping up of acid. The KL5M significantly reduces cost of ownership with no requirement to replace bulbs and a service life three times longer than lead acid batteries. The cap lamp is also intrinsically safe and CE Certified (EN60079-0:2004, EN62013.1:2002, EN50020:2002, EN50033:1991) for use in explosive atmospheres. The KL5M was first introduced to the market in 2003 and has undergone constant refinements and improvements. The cap lamp is designed to withstand the harshest underground conditions and is manufactured from impact and temperature resistant Makrolon plastic material. The KL5M when fully charged holds its charge until use and will provide 15 hours of continuous light. To prolong the life of the cap lamp battery, the Lithium-ion battery has an over charge protection system that will automatically cut off the circuit to protect the battery from being over charged. Additionally, there is an automatic power off in the cap lamp so that if the surface of the lamp or the LED is broken it will automatically turn the power off for protection. The 2007 version of the KL5M LED Li-ion Cap Lamp has many improved features from its predecessor. A purpose designed LED with an upgraded antistatic capacity provides luminous flux of 90-110lm and increased brightness at 7,000-11,000lux. A new radiator in conjunction with the purpose designed LED has significantly reduced the amount of heat experienced at the glass. In addition, the cap lamps flood and spot light settings are operated by an upgraded push button. As an added safety feature the cap lamp now also incorporates a low battery warning with the last hour of discharge flashing every 5-10 seconds to warn the user. And the version 2008 is mainly improved base the version 2007 to make the lamp absolutely water proof and better usage with the button switch. The KL5M LED Li-ion Cap Lamp has set a new standard in reliability and safety for miners cap lamps. NOTE: we have patent of the lamp design, the patent No. is ZL 2006 3 0176325.1
Product Features:
Safety: Contained in a sealed battery case, the product has a short-circuit protection, LED light head lamp and anti-static housing which makes it explosion proof. The miner's lamp is CE Certified for use in explosive atmospheres such as coal mines.
Reliability: Tough housing, optimized design, a solid LED light that uses high efficient IC drivers guarantee the product is durable and strong. The durable Li-ion battery has an over charge protection system to protect the battery from over charging. The cap lamp is suitable for operation under harsh mining conditions.
Portability: Small in size, light in weight, ergonomically designed, maintenance free, simple charging, easy operation. The cap lamp has received praise from many miners and major mining companies.
Efficiency: LED light provides bright, clear, white light. The minimum luminous intensity is 7000-11000lux (at a distance of 1m). The quality of the light is maintained throughout the entire discharge cycle which lasts up to 15 hours. The battery has a life cycle of 1200 charges and discharges.
Environmental: The cap lamp is made from environmentally friendly Li-ion battery and other non hazardous materials. The KL5M is an environmentally friendly product as per RoHS Directive.
Economy: The cap lamp incorporates an environmentally friendly LiMn2O4 battery as a power source. The light is an efficient, high powered LED with a service life of over 30,000 hours. With no need to replace incandescent globes the KL5M eliminates the cost of labor and replacement parts associated with traditional lead acid batteries.

Summary of the advantages of the prod ucts are:
1. the LED is specially designed for only us, the chip is made in a big radiator which well deals with the heating. 90% and up of other LED in the market are made in a very small radiator then connect the legs of the LED to an aluminum pcb as radiator which will be a problem as we research for a long time because there will be a gap between the LED and aluminum pcb after a certain time of usage, hence seriously affect the heating radiator, and hence accelerating the decay ratio of the LED. Our LED light is the latest version of 80-100lm to make the brightness of the lamp to be more than 10000lux in one meter.
2. with the minding function in the last hour by flashing softly in each 5-10seconds so that user can well use the balance time of the lamp. It is very good for the miners use our lamp in the mine.
3. Our power source is also specially made for us only. It is Li-ion battery of LiMn2O4 material which is the most safety with 5.5-6.9Ah capacity, light weight, small size.
4. The plastic parts of our lamp are made from famous German brand--Bayer PC material. This way is to make our lamp can bear the heat to 120 degrees, very good quality, anti-attached, not easy to deformation, durable, good looking and feels well.
5. the APCBs of the head lamp, the battery and the charger are designed by us. We have skilful and experienced engineers to design the APCB in the best working situation for the mines and for our lamps and chargers. This way we can well control the quality and improve the function frequently whenever better new ideas come up, including applying better components whenever available and improved the circuit design.
6. We frequently improve the design of the APCBs by modifying the circuit designs. Now the APCB of the charger is near the charging theory for the Li-ion battery; The APCB for the cap lamp with minding function and very good working functions too; The APCB for the battery is very safety, high efficient with many protection function.
7. We have strict testing of our product so that we can make sure the quality is in good situation. For example, we use 1.5 atmosphere pressures to test the lamps working under the water. Since 2006 to now, we have test for thousands of times and adjusted SOP of 18 times for the technical of production and 62 times modules of parts, finally we have made the lamps absolutely water proof since six months ago. And we will continue monitor the quality by testing and keep the Lean Production statue.
8. We have our own advanced injection machine to make the plastic parts so that we can make sure to use the best materials to make the parts and we can inspect the production of the plastic parts to make the plastic parts better quality.
9. We use all stainless steel to make the metal parts for best quality possible.
10. We have applied the production management of 5S; so that we can make sure the workers are strictly produce the goods to our requirements strictly.
11. We keep improving our quality as your back up so that you can feel release to open the market in the best way.
