Abstract: Temperature radiators are briefly discussed and their fixed spectral distribution for a given operating condition is mentioned. The generation of light in a high-pressure vapor discharge lamp and the relevant physical theory and mechanisms are described, including the effect of the introduction of a metallic element such as lithium. Formulas for the calculation of a lamp's light efficiency and flux as a function of the number of excited particles are given. Halides may be added as emission boosters. The addition of rare earth elements produces closely packed spectral lines. The conditions that metal halide lamps must meet for color television are considered. By introducing Hg, Na, Tl, In and Li into the envelope and adjusting energy ratios between the spectral lines, a 5000-K. daylight booster light can be produced. Some experiences with this lamp, the HQI 1000 C, are described and its technical parameters are given. A specifically adjusted combination of Hg, Tl, Na and Li—plus the halide as emission booster—yields a low-color-temperature lamp, the light of which can readily be mixed with that of 3200-K. incandescent studio lamps. For the blue-screen process special lamps can be designed by using In and Ga. Investigations have demonstrated that the three types of lamps are possible in principle. A unified type of lamp construction, based on the HQI 1000 C model, is used.
