Abstract: A positioning device includes a first substrate holder for holding the first substrate and a second substrate holder for holding the second substrate. The first substrate holder and the second substrate holder are mounted such that a distance between them is adjustable; and a distance-control element which has a body with a fluid inlet, a first substrate fluid outlet connected to the fluid inlet and which is directed towards the first substrate holder and configured to eject pressurized fluid from the body in the direction of the first substrate when the first substrate is located in the first substrate holder. A second substrate fluid outlet is provided connected to the fluid inlet and which is directed towards the second substrate holder and configured to eject pressurized fluid from the body in the direction of the second substrate when the second substrate is located in the second substrate holder.

Abstract: A phosphor composition may include first and second phosphors configured to emit light of a first and a second unsaturated color, respectively. The first unsaturated color may be associated with a first position in a CIE standard color chart adjacent to and above a position of a selected target color of the phosphor composition in the CIE standard color chart. The second unsaturated color may be associated with a second position in a CIE chromaticity diagram adjacent to and below the position of the selected target color of the phosphor composition in the CIE chromaticity diagram. Thereby, the position of the selected target color of the phosphor composition in the CIE chromaticity diagram may be located in an area defined by corner positions R=(cx; cy) given by R1=(0.645; 0.335), R2=(0.665; 0.335), R3=(0.735; 0.265), and R4=(0.721; 0.259).

Abstract: Various embodiments relate to a circuit support for an electronic circuit. The circuit support may include at least one conductor track, and an insulating matrix that is injection-molded over the at least one conductor path in such a way as to leave open at least a first region for connecting at least one electronic component of the electronic circuit. The circuit support may include at least one fastening aid that is formed from the material for the insulating matrix and/or from the material of the at least one conductor.

Abstract: A lighting may include at least one semiconductor light source which emits primary light, at least one phosphor region spaced apart from the at least one semiconductor light source and serving for at least partly converting the primary light into secondary light, and at least one filter disposed downstream of the at least one phosphor region, wherein the at least one filter is partly reflective at least to the primary light.
