Feature:

1. LED Solar Light: This solar light circuit board can drive one or more LED lamp beads or parallel light string in a variety of colours.
2. Easy Adjustment: White lamp beads are used by default, and other colour lamp beads can be used after modifying the parameters in batch.
3. Bright Lighting: Adopting peaking type inductance with high conversion efficiency, has long lighting time and high brightness as well.
4. Practical Using: Comes with light control function, which enables charging at day time and automatic lighting in the night, very useful.
5. Currents Modify: The battery discharge current is about 30ma by default, and the current can be conveniently changed in batches.

Welding Requirements:
1. The circuit board uses a large scale integrated circuit chip, which is sensitive to static electricity, and anti static measures must be taken when soldering, otherwise the circuit board will be damaged;
2. When assembling the lamps, the lamp beads should be welded first, and then the solar panels and batteries should be welded strictly in accordance with this process, otherwise it will cause damage to the circuit board.

Note:

Battery Discharge Current Adjustment: When the battery voltage and lamp bead colour are set, the battery discharge current is determined by the inductance, and the default inductance is 100uH. When the battery voltage is 1.2V and the white lamp is used, the discharge current of the battery terminal is about 30mA. When using other colours of lamp beads, you can change the inductance to obtain the discharge current you need, increase the inductance and reduce the discharge current, and reduce the inductance to increase the discharge current. The discharge current of the battery terminal needs to be controlled between 10 and 135mA. Exceeding this current range will damage the circuit board.
