This instructable is inspired by Tool Using Animal ( https://www.instructables.com/id/LED_Lightbulb/ ).
He has used two LEDs for his project and he has used a light bulb. We shall use only one LED and a male plug (pin) instead of an old light bulb.
Many of us want to make a simple night light or a mood light but dont want to run it on batteries or DC power sources. Here is a simple AC Mains solution for the LED newbies.
Caution: When dealing with power mains, safety cannot be understated. pl use your discretion before performing anything on your own for the first time.
Ok, so all the things we need:
1. One LED (10 mm or better still, one super bright led)
2. one 1000 Ohm 1/4 W Resistor for 110V AC Mains (We are on 220 V systems here in India - so use 1000 ohm 1/2 watt resistor)
3. One 0.47 uF, 250 Volt Capacitor for 110V AC Mains (We are on 220 V systems here in India - so use 0.22 uF 400 v capacitor)
4. One male socket plug / pin (With screws so that it can be opened and LED assembly can be fitted in)
5. Solder - optional (?)
Comments and mods welcome...
Step 1: Steps
Connecting the stuff:
For 110V Mains: (For 230V Mains, resistor & capacitor configs, as above)
1. Connect the 1000 ohm 1/4 W resistor to the longer leg (anode) of the led.
2. Connect the 0.47 uF, 250 volt capacitor to the shorter leg (cathode) of the led / super bright led.
3. preferably, solder the stuff
4. Now stick the assembly in a male socket plug / pin.
This is your night light / mood light / low voltage power saver - whatever you want to call it.
You can use a red led to improve night vision.
You can use a super bright led for enhanced brightness.
