junction loss fever temperature rise at room temperature near the temperature rises 1 ℃, LED luminous intensity will be correspondingly reduced by 1%, the package heat dissipation; to maintain color purity and luminous intensity is very important, in the past to use more ways to reduce the drive current and lower junction temperature, the majority of LED drive current is limited to 20mA or so.
However, LED light output with the increase of current, at present, a lot of power type LED drive curr
