    Properly Defining A Light Bulb As A Heat Source?

    Samuel Broadwater

      I'm trying to figure out how to properly model multiple light bulbs, with wattages ranging from 35W to 1000W, as heat sources. I've read that some like to put the the wattage on as a surface source on the light bulb model and others like to model the light bulb and apply the wattage as a volume heat source. My issue with both is I am getting unreasonable results when they are being mounted in a fixture to measure how much heat is generated when multiple light sources are reflecting on one material. Some of them get ridiculous (1100K or so).

       

      So how do you guys go about modeling the thermal properties for light bulbs and light sources in an external simulation?
