Hi @kalpa210 ,
You should be able to light up that area with around 10W give or take depending how bright you need it, by using a single higher power LED or a few smaller ones placed around the lens (4, 6, 8 etc.). Multiplying the LED voltage by the LED current will give an approximate power rating. This should at least get you started with experimenting to see which LEDs and wavelengths work best for you and the specific camera.
