hello members

I started a project with a little more work than I thought but that's not a problem then it takes just a little longer.

My current lamp (see photos below this post) has led and halogen, it comes to these LEDs are now blue and I want to replace for rgb.
but now I have about a few questions like how to connect them.

I want t o make it with Straw hat LEDs but the I must found holders to because the originals are with a connector.


in the drawing, I try to explain what I do not know and what I think.


Thanks for any response.

only led

led and full halogeen

Rule number one: You can't put LEDs in parallel. This means you can't feed 2 or 3 or 126 LEDs with one resistor. The first approach is 378 resistors and a controller that ranges from about 1.4 volts to 24 volts to give full range dimming with a small dead band near the zero voltage range. About 1200 ohms should do.

Another trade-off might be 3 LEDs in each series string with 820 ohms, but the dead band near zero volts will find the blue LEDs dropping out while the reds and greens are still running, all voltages being the same.

I'm afraid you have bitten off quite a lot more than you expected.

 

I think tis is more the way I have to make it.
This is good good way to do it right?
It is much more work but then my little project is a kind of bigger now.

I gonne look to LEDs @aliexpress is there something value`s or something to hold on with it.

 

Or with resistor network array
is that correct.
