The energy balance of high intensity discharge lamps

Abstract

Wen want to determine the energy balance of an HID lamp, by mapping the input energy and the energy flows to the total output energy of the lamp. For such a mapping, we need to determine the total spectral radiance. Therefore we will analyze absolute calibrated integrating sphere measurements of the complete spectrum. The current focus of the project is the infared range of the spectrum. New in this work is that absolute calibrated integratng spere measurements will be employed in the infrared part of the spectrum. Calibrating an integrating sphere in this wavelength range will be discussed
