4. Below the zener reference voltage Vz, all the current flows through LED and as the voltage rises to

Vz, the zener diode “breakdown." If the voltage tries to rise above Vz current flows through the

zener branch to keep the voltage at exactly Vz.

5. When the LED is connected using serial circuit, if either piece of LED is no light up but current

can’t flow through causing others to light down. In new design, the LED is parallel with zener diode.

if either piece of LED is no light up but current can flow through causing others to light up.

6. Soldering Condition

Careful attention should be paid during soldering. When soldering, leave more then 3mm from
