Relative Light Output vs. Junction Temperature at IF=350mA, TA=25℃

Hi Chaps

Using the Relative Light Output vs. Junction Temperature at IF=350mA, TA=25℃ plot is it a fair assumtion that the same relative light output holds true at higher currents.

The seould data sheet quotes for at 350mA....Is it ok to use the same figure at 1A?

I've wondered this also...I don't think it does. The junction temp is the big kicker. At higher current levels (like 1 amp), I think it would take a lot of design work to keep that kind of junction temp. Maybe we could design a radiator system for our heatsinks. :thinking: :grin2:

maybe i could use it as a heat source to keep me warm during 24 hour races...especically if its wet hehe.
