| 20090050846 | Illuminant and Light Source Containing the Same, and Method for Producing said Illuminant - An illumination from the class of oxynitridosilicates, doped with bivalent europium and comprising a cation M2+, said illuminant corresponding to the basic formula M | 02-26-2009 |
| 20090261366 | OPTOELECTRONIC COMPONENT - An optoelectronic component with a semiconductor body that comprises an active semiconductor layer sequence is disclosed, which is suitable for generating electromagnetic radiation of a first wavelength that is emitted from a front face of the semiconductor body. The component also comprises a first wavelength conversion substance following the semiconductor body in its direction of emission, which converts radiation of the first wavelength into radiation of a second wavelength different from the first wavelength, and a first selectively reflecting layer between the active semiconductor layer sequence and the first wavelength conversion substance that selectively reflects radiation of the second wavelength and is transparent to radiation of the first wavelength. | 10-22-2009 |
| 20090278441 | Luminescence conversion of led - A luminescence conversion of LED, which uses a blue emitting chip and two illuminating substances, whereby one emits a red and the other a yellow to green. Both illuminating substances are separated upstream from the chip. | 11-12-2009 |
| 20090322209 | Luminescent Substance of the Class of Nitride Silicates and Light Source Having such a Luminescent Substance - A phosphor from the class of nitridosilicates from the M-Al—Si—N system, comprising a cation M, wherein M is represented by Ca alone or is represented by a mixture of Ca with at least one further element from the group Ba, Sr, Mg, Zn, Cd, Li, Na, Cu, wherein the phosphor is activated with at least one element from the group Eu, Ce which partly replaces M, characterized in that the phosphor forms a phase that is to be assigned to the system M3N2-AlN-Si3N4, wherein the atomic ratio of the constituents M:Al ≧0.375 and the atomic ratio Si/Al ≧1.4. | 12-31-2009 |
| 20100096592 | Red-Emitting Luminophore and Light Source Comprising such a Luminophore - A red-emitting phosphor composed of an M—Al—Si—N system, comprising a cation M, wherein M is represented by at least one of the elements Ca or Ba or Sr and, if appropriate, can additionally be combined with at least one further element from the group Mg, Zn, Cd, wherein the phosphor is activated with Eu, which partly replaces M, and wherein the phosphor additionally contains LiF | 04-22-2010 |
