Abstract
The invention relates to a light emitting device having a radiation emitting element, for example a light emitting diode, and a luminescent material which is able to absorb a part of the radiation sent out by the radiation emitting element and to send out light with a wavelength which is different from the wavelength of the absorbed radiation. The device further has diffusing particles which are able to scatter a part of the radiation sent out by the radiation emitting element, and/or to scatter a part of the light sent out by the luminescent material. The diffusing particles are of non-activated luminescent material, through which production is simplified.
