Abstract (en)
[origin: WO2009135620A1] A lamp device comprising illuminant (40; 94), which emits a primary radiation on applying a voltage thereto and solid particles (64, 66), at least partly enclosing the illuminant (40; 94) and which interact with the primary radiation. The particle number density (64, 66) changes in at least one direction away from the illuminant (40; 94) from a first particle number density to a second particle number density.
