Are you also calculating radiation? Would you be willing to post your model on here to have it examined?
Please see the model as requested.I haven't been paying attention to the radiation.
I've done simulations such as tutorials in this video, but I'm not sure the use of Junction so I applied Volume source heat for the LED.
I tried re-running the simulation without Contact resistance (I removed some parts: Thermal pad and Holder), the result temperature of LED decrease (around 75 degree Celsius) but it still higher than actual temperature.
Thanks and regards
Did you get this resolved? I am considering purchasing Flow for my startup company to use to model some LED bulbs we are designing and need to know how hard it is to produce meaningful and reasonably accurate models i.e. ones that generate useful results.
