Many years having passed since I last looked at an electrical circuit, I been asked to design an electrical circuit at work.
We make tonic water, and the idea is to create a holder for bottles with a built-in UV light rigging. Due to the relative efficiency, robustness, cheapness etc, I am going to use LEDs. Due to the fluorescence of quinine, we expect this to create quite a cool effect in nightclubs and the like.
My plan is to set up three 360nm UV LEDs (Vf 3.4V, I=20mA) in parallel. My supply voltage will be 10.5V.
My question is, will I need one resistor for each LED, or just one bigger one for the entire circuit? The LEDs are identical. Also, what resistance will I require.
Any help much appreciated!
