Further improvements of the efficacy of HID lamps require a better understanding of the energy balance of these lamps. An energy balance provides an overview of the most important energy flows and energy conversions. Such an energy balance is determined by using a calibrated integrating sphere setup suitable for spectrally resolved measurements from 250 nm to 10 µm. Being able to predict these energy flows is crucial for lamp development. For these predictions a one dimensional lamp model is made. Spectrally resolved measurements are used to estimate the broadening constants of the radiating species. By using the same broadening constants a comparison is made between the predicted and experimentally determined energy balance for several lamps outside the calibration parameter range.
