Installation Attention:
It consists of 53 identical white transparent LED lamps. After the lighting, it will change the regular color of seven colors. When in the test, you should stay a few seconds after lighting to see the transformation of the lantern. Welding position is not distinguished, welding at random position, long foot as positive pole.

Schematic Diagram(PCB-B):

Working Principle:

From the schematic diagram, when connected with 3-5V, 18pcs LEDs are divided into 3 groups. When the power is on, one of the 3 transistors will be the first one to be connected.
If Q1 is the first connected, the LED1 group is lit. Due to the Q1 conduction, capacitance C2 close to 0V and Q2 to 0V too; Group LED2 goes out. At that time high voltage flowing from Q2 to C3 increases the Q3 voltage, thus connecting Q3 in this circuits; Group LED3 is lit. In this case, Q1 and Q3 collector are low level, group LED1 and LED3 is lit, LED2 goes out.
But when power flows through R2 and charges the C2, the base voltage of Q2 gradually increases; when Volt is over 0.7V, Q2 is connected, and group LED2 is lit. At the same time, base voltage of Q3 decreases, Q3 is cut off, group LED3 goes out. In all, the circuit repeats the process described above, and the three group Leds will be lit by turns, 2 of which will be lit at the same time to reach the waterfall light effect.
