Previously we introduced LED night lamp circuit for 110V. Today we introduce same circuit for 230V. Also here, we used white LEDs for D6 to D15 and D5 Zenar Diode used as a voltage limiter. The circuit uses 30mA current. So that, this night lamp good solution against to the higher power consumption lamps. You can use this night lamp to your room.
C1 – 0.47uf/250v (474) Polyester
C2 – 100uf/50v Electrolytic
R1 – 270K/0.25W
R2 – 4.7Ω/0.5W
D1...D4 – 1N4007
D5 – 1N4754
D6...D15 – 10 x 8mm White LEDs
Be careful works with electricity.
Build this circuit on good quality PCB.
