Normalized Luminous Intensity vs. Junction Temperature
When mounted in a 10°C/W socket and operated at Absolute
Maximum Electrical conditions, the display will show an LED
junction rise of 17°C. If T
Under these conditions the following Figure „Max. LED Junction
Temperature vs. Socket Thermal Resistance“ shows that the l
be 75% of its 25°C value.
