Hey Guys,
Electronics just fascinates me........
But I am really dumb when it comes to working on it.
I have a night lamp that glows on neon bulbs. I want to replace them with LEDs so that the life will be longer.
The circuit is like the below but to a 230V power supply - from main power supply, this is linked to MPET D105K2E Capacitor and a resistor, and from there, the neon bulbs are connected in a series.
I am not trying to save the power of the lamp. One of the neon bulbs were fused within a matter of days. Not sure what has caused this - may be the voltage supplied is too high for those tiny fellows to handle. As they are in series, the lamp didn't work. I just removed the fused one and connected the others and got the lamp glowing. Again, in a few days, another one went off. So, I thought replacing them with more LEDs, say eight numbers, could get the lamp running at least for a year.
1. What do you think? Would that work?
2. And do you think the LEDs are reliable than the neon bulbs?
3. Is there a way I could connect them in parallel, of course, adding more resistors?
4. Do the LEDs produce more heat?
5. And could heat be the cause for the neon bulbs to go off quickly?
The image below shows the serial connection of the Neon bulbs - the connection starts with a resistor and then the series of bulbs and the end goes to the main power line.
This image shows the main power line coming to the MPET D105K2E Capacitor from right (black wire) and a resistor connected parallel to the capacitor and this line goes to the resistor in the first picture.

If needed, I would try to get you the resistor values shortly.
Really very sorry for the poor quality.....
I hope my description of the issue and my question is clear. :smile:
