A simple method for the power balance analysis of HID lamps
PosterHildenbrand, V.D., Rijke, A.J., Gendre, M.F., Haverlag, M. & Kroesen, G.M.W. (2012). A simple method for the power balance analysis of HID lamps.
Improvement of the efficacy of high-intensity discharge lamps and, for instance, the development of
Mercury free discharges require a good understanding of the power balance and loss factors involved.
Comprehensive measurements from the ultraviolet until the deep infra red are mandatory in order to
separate the role of different lamp components. They are normally not possible in a development
environment. The objective is therefore to develop a simple, quick method with standard
measurement techniques. Using Mercury free lamps as example, a method is derived to extract the
respective loss factors and contributions from wall temperature measurements in the middle of the
discharge vessel and visible power measurements.
