May i ask what is the maximum temperature of cree xre led
As my LED is getting quite hot with direct drive like rising to 40*c in a min
So i wanna know at which stage my light can endure
Quantitatively, let say 40 degree c. or others
I understand that LED can sustain a pulse of high temperature, like when you solder a bare chip on board
But it seems that CREE's data poop didnt mention the continuous operation temperature
Would someone tell me?
The temperature of rapid degrading of phosphorus powder is also important
Thanks
