This one I am using for testing and the other one I have just uploaded Clear color LED I am gonna use.

 

Hello,

The image you where showing is from this led:

Yeah. I am using this Type LED for testing.

 

hi,
This is a clip from that Amazon advert:
Clear Round Infrared 940 nm DC 1.2V 30mA 100mW) Lighting Bulb Lamps Electronics Components Light Emitting Diodes

So the maximum current is 30mA, so recalc the resistor values to suit 1.2v at 30mA.

If you still have insufficient IR radiation choose a higher power LED.

I think it will work After I make a PCB and do testing I can say for sure.

You think what will work?

Your three LED strings should have a 47Ω resistor in series with the LEDs. The string with two LEDs needs a 82Ω resistor (using standard resistor values. Go back to ericgibbs or my calculations to see why.

I have placed a 57Ohms resistor around 3 LEDs in series and 100 ohms with 2 LEDs in series.

On calculating I got 24.56mA for 3 LEDs and 26mA for 2 LEDs. So this will work right. there will be no issues.

 

hi R,
It should work OK.
If the operating range of the remote is insufficient, you will have to use higher powered LED's

Ok, I will now make it on zero PCB and test it by sending the signal through ATMEGA328P used as a custom Arduino for control.
