Hi all gurus and experts, i got a few question about a triple setup in a single cell powered light, what is the different and advantage of running 3 emitter in parallel vs in series? In a parallel setup, lets say i got a 3amp measurement at the tailcap, does it means that each emitter is drawing 3 amps or is it 3/3= 1amps? and how does this differ in a series setup?
Besides, which is a more ideal setup, a parallel setup or a series setup with a boost driver?
Thanks
parallel device current: 3/3=1 [EDIT: where 3A is measured on the string]
series device current: 3/1=3 [EDIT: where 3A is measured on the string]
I don’t want to be unfriendly, but Google would have told you that.
Parallel emitters are cheap and easy for flashlight folks. Series emitters are expensive because of the more specialized boost driver required. Maximum power achievable in parallel with our current technology is higher than maximum power achievable in series (on one cell). Nobody has published like-for-like testing to see which is more efficient or which stays in regulation longer when run at similar output power levels.
