| 20080251764 | Carbidonitridosilicate Luminescent Substance - The invention relates to a luminescent substance consisting of a doped host lattice which absorbs at least one part of exciting radiation when it is excited by a high-energy radiation, thereby releasing an energy-poor emission radiation. The host lattice is embodied in the form of a carbidonitridosilicate-based compound. An illuminant which is used for producing white light and comprises a light emitting element and said luminescent substance are also disclosed. | 10-16-2008 |
| 20090294788 | LIGHT EMITTING DEVICE WITH A NON-ACTIVATED LUMINESCENT MATERIAL - 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. | 12-03-2009 |
