摘要:
An incandescent lamp for a vehicle headlight comprising a transparent vessel that encloses at least one filament and the vessel is at least partly covered with a coating. The coating comprises at least one pigment, which is arranged such that light emitted by the at least one filament and traversing the coating is transformed to transformed light. The transformed light is characterized by a chromaticity according to the CIE 1931 xy-chromaticity with y being in between the Planckian locus and y=0.5*x+0.205 and 0.36
