230 V 50Hz AC (or 110V 60Hz) Main Operated LED Powerful NIGHT LAMP Circuit Diagram.

Electrical Technology
  230 V 50Hz AC (or 110V 60Hz) Main Operated LED Powerful NIGHT LAMP Circuit Diagram.

Please Note That if you want to make this circuit at home, then read carefully all the instructions.
Also, If you have plane to use this Circuit on 110V 60Hz instead of 230V, 50Hz, or want to modify this circuit, Then See the Section ” Common Question about this Circuit” below the “instruction”.
Also Note that here is two circuit diagrams, so the first one is recommended. the second one (as i tried) is for experimental purpose only, so don’t try the second one at home. i will be not liable for any Damage/Loss(es). Please be careful because your safety is better than everything.

Below is a very simple , power full and extra bright LED NIGHT LAMP circuit diagram than can be operated directly from 230V AC 50HZ MAINS Supply.
Description and important instruction and data are given below (step by step).

230V AC Main LED Night lamp
DATA :
LED 24 No (3.2V / 25mA each)
C1 = 0.22μF / 1000V (Polyester Type)
R1 = 1kΩ / 3W
INPUT :
230 V AC
50HZ

OUTPUT:
15 Watts.

Instruction:
  • Try to make this Circuit on a General purpose PCB.
  • White LED’s are recommended in this circuit.
  • Use Polyester type Capacitor (C1)
  • Do not operate on DC. Operate only on AC 230 V.
  • as this is an AC (230V) Operated Circuit. So pleas be careful about your safety
  • Do not Touch any wire while operating the circuit.
  • Please be careful because your safety is better than everything.

Common Questions about this Circuit:

  • Power Consumption of the Circuit is about 2Watts
  • Volt-Amp rating of each LED’s is 3.2V -25mA
  • For 100No of LED’s,(connect back to back as shown above) reduce the R1 to 220Ω 1W. and increase C1 to 0.47μF/400V
  • For 50No of LED’s, (Connect back to back as shown above). Change R1 to 220Ω -1/2 or 1/4 Watt and change C1 to 0.47μF/400V 
  • By reducing the resistance to 220ohms 1/4 watt you can further reduce the power consumption of the circuit, as it is Night Lamp 
  • If Your plane is to use this circuit with 110V 60Hz AC main Supply then change CI to 0.68μF (684 / 250Volts) polyester capacitor. Reduce the value of  R1 to 220Ω 1/2 watt. Ensure that you use 3.2 volt 25mA Bright LED’s
  • With 0.1μF you can connect 1 pair of LED’s (back to back)

 The second one ( Circuit diagram) which i have tried so here is the result.

110VAC 60Hz AC main Operated LEDs Lamp

in real ( i did not make the circuit on PCB, that’s why i m saying that pleas be careful) supply voltage off.
