3.7V 2600mAh Smart Home LED Light Lithium Battery Design
Foreword: As the household product market expands, new applications of household LED lights such as mirror LED lights and wardrobe LED lights have appeared. Because these products are used indoors, they generally have high safety, energy saving and environmental protection requirements. Different from some nickel-cadmium/nickel-metal hydride LED lamp batteries, our company adopts a household LED lamp lithium battery solution, which is the most advanced LED lamp battery application solution.
The solution adopts a well-known brand 18650 lithium battery cell design that meets UL/CE safety standards. The main control IC and MOS tube used on the protection board are imported components. All materials use standard components that meet environmental protection requirements.
1. The design requirements of the furniture LED lamp lithium battery:
According to product specifications and customer requirements, design smart LED light lithium batteries that match household products, and integrate the safety and environmental protection and energy saving of smart lithium battery LED lights into the solution. While meeting daily lighting use, it can also be used as LED Emergency power use. The LED lamp lithium battery developed by our company requires that it can drive the makeup mirror to work continuously for one month, working for 30-60 minutes a day, and the LED working current is about 200mA.
2. Smart home LED lamp lithium battery design scheme:
1) Protection board (PCM): It is mainly designed to protect the rechargeable smart LED lamp lithium battery. Due to the chemical characteristics of the lithium battery itself, it needs to provide intelligent overcharge, overdischarge, short circuit, overcurrent and overtemperature protection Features. To avoid safety accidents such as burning and explosion.
2) Protection IC (Protection IC): The main protection function chip of the design scheme, which constantly monitors the online function of the battery. Make the battery core work in a safe, stable and efficient range.
3) Overcurrent protection sheet (PTC recoverable fuse): Mainly designed for secondary protection function. PTC has the dual functions of over-current protection and automatic recovery. The PTC in the LED light lithium battery can prevent the high-temperature discharge of the battery and the occurrence of unsafe high current.
4) Battery: 18650/2600mAh/3.7V well-known brand lithium-ion battery, with high energy ratio and high safety.
5) Field effect tube (MOSFET): MOSFET, which acts as a switch in the protection circuit, always keeps the voltage at both ends of the load from increasing or decreasing, ensuring voltage stability.
6) Light-emitting diode (LED): LED lamp battery solution uses high-brightness, environmentally friendly and energy-saving LED.
7) Battery pack packaging: PVC casing.
