| Zusammenfassung | We have developed a physical model for the spectral behaviour of the radiation of tungsten filament lamps. The model is based on Planck’s radiation law, published values for the emissivity of tungsten, measurement geometry, and measured values for a residual correction function. The model can interpolate and extrapolate spectral irradiances of 1-kW FEL and DXW type lamps, with additional uncertainties better than 1 % within the wavelength range 340 - 850 nm. The model makes it possible to estimate spectra of incandescent lamps with uncertainties of the order of 2.5 % based on illuminance and colour temperature, or even illuminance and resistance measurements only. |
