HIGH EFFICIENCY EMITTER FOR INCANDESCENT LIGHT SOURCES

WIPO Patent Application WO2004079773

A3

An emitter (F) for incandescent light sources, in particular a filament, capable of being brought to incandescence by the passage of electric current is obtained in such a way as to have a value of spectral absorption alpha that is high in the visible region of the spectrum and low in the infrared region of the spectrum, said absorption alpha being defined as alpha=1-rho-tau, where rho is the spectral reflectance and tau is the spectral transmittance of the emitter.
