230 Volts LED night light project.
Here is an addition to the popular LED indicator lights.
I have made some LED lamps as well for 230 Volts. I used an old base from a discarded compact fluorescent lamp. It got the B22 socket and has a wider base which is excellent for the LED project. I use them as night lights in my house so I don’t have to switch lights on and wake myself up too much when going to the loo.
Of course an Edison E27 base can be used as well and for 110 Volts use 2 *8k2 or 10 k Ohms resistors in series.
3552 The B 22 base with 4 * 8k2 ohms , 1 Watt resistors and the 1 N4007 diode.
3553 Side view of B 22 base.
3554 9 LED’s glued with araldite to a transparant pvc base. (8 blue, 1 green).
3559 Section of LED’s under test. I find it very handy to test for correct polarity when a string of LED’s is soldered. It saves a lot of messing about later on when things don’t work when a LED is put in the wrong way around. I use a 12 Volt power supply limited to 10 mA, so I can’t blow up any LED’s.
3561 Test run at 230 Volts. Current is only 3.17 mA.
3565 LED lamp going in my lounge.
3566 LED lamp from different angle.
Regards, Raymond
Keen to hear ideas or see photo’s from other forum members who have built some LED lamps.
