40 LED AC 230V Bright Light Circuit Diagram | Transformer-less

This is an improved version of the circuit shown in the previous post.

Components Required:

Resistors:
R1 - 100E, 2W
R2 - 390K, 1/2W

Capacitors:
C1 - 0.27uF or 0.22uF, 400V or 630V
C2  - 10uF, 400V

BR - Bridge Rectifier ( DB107 or W04)
MOV - 275/20
LED - Ultra bright white LED(40 numbers)
General purpose PCB
Note:Always ask the forward voltage and current of the LED you are going to use before purchasing.

If you are going to use LED's of different current rating, please use the following calculation.

$X_{c}= \frac{1}{2\pi fC} Ohms  ---- (1)$

$X_{c}= \frac{V_{RMS}}{I} Ohms  ----(2)$

Where,
f - Frequency in Hertz (Hz)
C - Capacitance in Farads (F)
$V_{RMS} \text{- Mains Voltage Volt(V)}$
I - Current in ampere (A)

Known values,
f - 50Hz
V - 230V
C - 0.27uF (This is the value of C1)

Comparing (1) and (2), 


$$\frac{1}{2\pi fC} = \frac{V_{RMS}}{I}$$
$$\Rightarrow I = V_{RMS} \times 2\pi fC$$
$$\Rightarrow I = 230 \times 2 \times 3.14 \times 50 \times 0.27 \times 10^{-6} [\because \mu = 10^{-6}]$$
$$\Rightarrow I = 19.4994 \times 10^{-3} A$$
Rounding off, we get:
$$\Rightarrow I = 19 \text{ } mA$$
