摘要:
The invention concerns an illumination system for generation of colored, especially yellow, amber or red light, comprising a radiation source and a fluorescent material comprising at least one phosphor capable of absorbing a part of light emitted by the radiation source and emitting light of wavelength different from that of the absorbed light; wherein said at least one phosphor is a yellow to red-emitting europium(II)-activated oxonitridoaluminosilicate of general formula EA2-zSi5-aAlaN8-aOa:Euz wherein 0

The invention relates to an improved red light emitting material of the formula M1−yA1+xSi4−xN7−x−2yOx+2y:RE whereby M is selected out of the group comprising Ba, Sr, Ca, Mg or mixtures thereof, A is selected out of the group comprising Al, Ga, B or mixtures thereof, RE is selected out of the group comprising rare earth metals, Y, La, Sc or mixtures thereof and x is ≧0 and ≦1 and y is ≧0 and ≦0.2. This material is believed to crystallize in a novel structure type that comprises two individual lattice sites for rare earth metal incorporation, which leads to an improved lighting behaviour.

摘要:
A lighting device having a cell structure (101) of polygonal cells (105), which is a heat sink, and light sources (103) arranged to be cooled by the cell structure. The light sources are arranged in at least some of the cells, one light source in each cell. The light sources are attached to the cell structure and electrically connected with the cell structure, which in turn is arranged to provide the light sources with power.

A solid-state lithium secondary battery includes an electrode body including a positive electrode containing positive electrode active material particles and solid electrolyte particles, a negative electrode, and a solid electrolyte layer composed of solid electrolyte particles and disposed between the positive electrode and the negative electrode. In the solid-state lithium secondary battery, the solid electrolyte particles contained in the positive electrode and the solid electrolyte particles of the solid electrolyte layer are each composed of a lithium ion conductive material represented by chemical formula Li+(12−n−x)Bn+X2−(6−x)Y−x (Bn+ is at least one selected from P, As, Ge, Ga, Sb, Si, Sn, Al, In, Ti, V, Nb, and Ta; X2− is at least one selected from S, Se, and Te; Y− is at least one selected from F, Cl, Br, I, CN, OCN, SCN, and N3; and 0≦x≦2) and having an argyrodite-type crystal structure, and the positive electrode and the solid electrolyte layer are obtained by firing, at 100 to 400° C., a stacked body of a positive electrode precursor and a solid electrolyte precursor.

A mixing element has a grid which includes a plurality of rows parallel to each other and a plurality of deflector elements which project from the grid and are inclined in relation to the grid plane normal. All deflector elements of one row are inclined in the same direction. The deflector elements of at least two immediately adjacent first rows are inclined in the same direction. The mixing element is used in an exhaust system of an internal combustion engine.
