Smart Home LED lights 18650 lithium battery Solution

- Mar 22, 2017 -

Foreword: With the widening of domestic market, the reason that Mirror LED lights, wardrobe LED lights and other household LED lights are applied to indoors, propose high security and energy saving requirements. Compared with NiCd/NiMH battery LED lights, home LED lights Lithium batteries the most advanced LED lights Lithium battery in the world.
The 18650 lithium battery is approved by UL/CE safety standards, and main control IC and MOS tube used on protection board are all imported components, in addition, all standard Parts of Materials meets the environmental requirements.
1) The design requirements for Smart Home LED lights lithium battery 
Based on the demands of product specifications and consumers, smart LED light Lithium batteries matching household products, taking safety and environmental protection energy conservation into account, meet routine lighting requirements, and can be used as LED emergency power. The LED lights Lithium batteries can drive cosmetic mirror to work continually for a month, work time of 30-60 minutes daily, 200mA Operating Current of LED. 
1.Protection Board (PCM): designed for rechargeable smart batteries to protect circuit, the protection board needs to provide smart power calculation, overcharge, over discharge, short circuit, over current protection to avoid the hazard of burning and explosion because of its chemical properties.
2.Protection IC: The main function of the design is to protect the chip, and constantly monitor the situation of overcharge, over discharge, over current, short circuit occurring, so that the chip can operate in a safe, stable and efficient condition.
3.Overcurrent protection films (PTC): mainly for secondary protection design. PTC resettable fuses with overcurrent protection, automatic recovery dual function. Battery products in the PTC can prevent the battery from large current discharge with high temperature.
4.Battery Cell: 18650/2600mAh/3.7V known brand lithium-ion battery cell, with the high energy ratio and security.
5.MOSFET: acting as a switch in the protection circuit, and balances the voltage across the load
6.LED: LED light battery with high brightness, energy-saving LED.
