7. Comparative Tabulations of the Properties and Energy Consumption of Lamps
Lamps are not only radiation sources but also heat sources. The increasing importance of integrated illuminating installations - included in the air-conditioning and noise control measures - requires also knowledge of the energy balance of lamps. The energy balance represents the division of performance into heat of conduction and convection heat as well as the entire radiant flux (radiation power). In this context, it is of special importance how the total radiant flux splits up into the individual wavelength ranges.
