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

  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).

                                           (click image to enlarge)
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.

  1. Can you please tell me what is the purpose of connecting wire between two LED lines
    after each LED
    And what is benefit of making two groups of LED's

    (1).. Making two LED's in Parallel and so on.
    (2).. Actually it seems that there are two Strings or Two LED's Groups,,,but if you design this circuit on general PCB or in any simulation program. you will find that it is the same (i.e one and only one) String or Group of LED's.

  3. I got the 2nd point
    1)why to make LED's parallel?
    No current flows through these wires at any time
    what if these wires are not inserted

  4. Dear FURQAN463@
    If you design this whole circuit in a notebook paper without inserting that wires, you will find that their will be 4 strings each having 6 LED's. and these LED's will be in Series.
    So then try to make the same circuit with that specific wires. it will clear that each of two LED's will be in parallel.

  6. Awesome circuit. Pretty simple. I set up this way. however the resistor in the circuit is burning out in less than a minute. Im waiting eagerly for a solution.
    I connected 24 leds with one resistor and one capacitor in series.
    1kohm/3w
    .22uF/1200w

    Heya i am for the first time here. I came across this board and I in finding It truly helpful & it helped
    me out much. I'm hoping to give something again and help others like you
    aided me.

  8. Good afternoon friends.
    My name is john, my passion to design an LED star lighting system is very intense but i don't have the complete knowledge yet, that is why i decided to access the internet to acquire more knowledge, in search i found your blog, with what i saw i was amase and as well happy because i know i can get some aid from you.

    My question is if my main is 220V, how can i connect 50 LED in series .i dont know the value of resistor and capacitor and diode . id you dont mind plz give me diagram to use in series with the 50-LED?

  9. What is purpose of inserting the capacitor in series with circuit ......

  10. what is the benefit of this grouping of led's ?
    and what is the advantage of this type circuit over a circuit in which we connect all led's in series and a resistor accordingly without capacitor ?
    also, what is the purpose of capacitor in first diagram, doesn't it cause over-voltage in the circuit whenever the ac cycle gets reversed ?

    also, isn't it dangerous to connect capacitor in parallel to ac main (second diagram) ?
