on video 10 watts led run direct 230 volt AC


 10 watts led run direct 230 volt AC

A simple circuit diagram for a single LED on AC Mains 110v or 230 volts or even DC battery!!!

Parts:


1. An LED - 5mm or 10mm of any colour

2. A diode, preferably 1N 4007

3. A resistor of 2 watts or higher rating, of value anywhere from 22 kilo ohms up to 100 kilo ohms.

4. A two pin male plug (hollow)


Lower resistor values ​​will give more brightness and higher values ​​will prolong LED life. So choose the tradeoff, depending on requirement.


Lower wattage of resistor like 1/2 watt or lower will not do and may burn since they are meant for 6v DC circuits, not for 220v AC Mains.


Assembly:

1. Connect the black anode of the diode to the negative of the led.

2. Connect the resistor to the positive of the LED.

3. Connect the free ends of the diode and resistor to the male pins.


Done. See the attached pic for clarity.


Another circuit with the diode connected "across" the LED is also attached. A bulb base adapter is used instead of a male pin.


It should work on 110v AC as well as 220v AC Mains systems.


DC Feature:


It will also work on any battery!!

Edited: April 2014

This instructable is becoming popular and common sense tells me that despite the "important" disclaimer about being proficient in working with AC Mains, many new people may also venture into making one.


So few guidelines as below:


Since only two components are used, both of them have to be robust to withstand AC Mains load.


1. The diode that i have used is 1N4007.


This 1N4007 diode is rated for 1000 volts and hence is robust to withstand both 110 v AC as well as 220 v AC Mains that different countries follow. Its also readily available, i guess.

2. The resistor 22 kilo ohm and above, should be rated for at least two watts or higher.


This will ensure that it will not burn due to continuous operation. A resistor is a current limiter. It limits the AC Mains current and converts it to heat and then dissipates it.


HEAT is a problem, since the capacitor is not used. However, since a higher wattage resistor is used, it will not fail. Lower wattage resistors will fail and can cause damage.


Please be responsible and thoroughly test your work.


3. I could not use a capacitor (non-polarised ceramic capacitor for AC Mains) since space was a constraint inside the male pin.
