This is a Compact LED Light on the lines of a COMPACT FLUORESCENT LIGHT. (CFL). It runs on 220 Volts AC or can also be made to run on 110 volt AC, if the value of the CONDENSER is changed to .47uF / 250Volts, AND the RESISTOR is changed to 1K / 1Watt.
Step 1: STEP-1
30 Extra bright White LED's of 5mm size.
3 Strips of Sun-mica Lamination Board.
One Condenser- value of 0.22uF / 400 Volts.
One Resistor- value of 1K - 1/2 Watt.
Making of the base BOARD.
Three strips of Sun-mica Lamination Board, is cut to size as to make a Triangle to fit the inside of the PVC base of the light. The base is taken from the bottom portion of a fused CFL light, as shown in STEP-3.
The length of the three strips of Sun-mica Lamination Board is to be determined by you, but 4.5 inches will do.
Drill small holes for the legs of the LED to penetrate through the board.
Each 3 sections of the board is laid together and taped with cello tape at the back to reinforce it and hold it together.
Step 2: STEP-2
EXTRA care should be taken to maintain the POLARITY of the LED's.
For this reason see the placement of the LED's as shown in the diagram
with the long and short legs of the LED's.
Long leg = + (plus) . Short Leg = -.(minus)
Step 3: STEP-3
and how the Capacitor and Resistor are fixed to it.
The base of he light is made of the lower portion of a fused CFL tube light.
The two leads goes to the bottom of the base.
Step 4: STEP-4
Each legs of the 4-LED's are soldered in the middle and so on......................
Step 5: STEP-5
The Capacitor and Resistor are put inside the bottom housing taking care that they should not
short circuit. Place a small plastic piece between them.
Cut a plastic bottle from the top so that the diameter fits the bottom housing and tape it to the base.
Step 6: STEP-6
Fix it in an electric bulb holder and switch it on and ENJOY the soft light.
Step 7: STEP-7
For those who wish to get an even brighter light, then they can MODIFY it by
Using 3 Capacitor and 3 Resistor as shown in this Circuit Diagram of STEP-7.
