An optical converter for producing colored or white light from blue excitation light is provided. The converter has good scattering properties to be able to produce nearly white light from the scattered blue light components and the scattered, converted yellow light components. The optical converter includes material including one or more of a YAG ceramic, a LuAG ceramic, and a magnesium-aluminum ceramic exhibiting strong scattering.

A feed-through component for a conductor feed-through which passes through a part of a housing, for example a battery housing, is embedded in a glass or glass ceramic material and has at least one conductor, for example an essentially pin-shaped conductor, and a head part. The surface, in particular the cross-sectional surface, of the head part is greater than the surface, in particular the cross-sectional surface, of the conductor, for example of the essentially pin-shaped conductor. The head part is embodied such that is can be joined to an electrode-connecting component, for example an electrode-connecting part, which may be made of copper, a copper alloy CuSiC, an aluminum alloy AlSiC or aluminum, with a mechanically stable and non-detachable connection.

A feed-through, in particular a feed-through which passes through a housing component of a housing, for example a battery housing, such as a battery cell housing. The housing component includes at least one opening through which at least one conductor, for example an essentially pin-shaped conductor, is guided. The pin-shaped conductor is at least partially surrounded by an insulator, for example made of a glass or a glass ceramic material. The at least one conductor connection, for example of the essentially pin-shaped conductor and/or of the housing component with the insulator, which is a glass or a glass ceramic material, is formed, the connection being an ultrasonic welding.
摘要:
A method for producing a cavity in a substrate composed of hard brittle material is provided. A laser beam of an ultrashort pulse laser is directed a side surface of the substrate and is concentrated by a focusing optical unit to form an elongated focus in the substrate. Incident energy of the laser beam produces a filament-shaped flaw in a volume of the substrate. The filament-shaped flaw extends into the volume to a predetermined depth and does not pass through the substrate. To produce the filament-shaped flaw, the ultrashort pulse laser radiates in a pulse or a pulse packet having at least two successive laser pulses. After at least two filament-shaped flaws are introduced, the substrate is exposed to an etching medium which removes material of the substrate and widens the at least two filament-shaped flaws to form filaments. At least two filaments are connected to form a cavity.

A feed-through, in particular a feed-through which passes through part of a housing, in particular a battery housing, for example made of metal, in particular light metal, for example aluminum, an aluminum alloy, AlSiC, magnesium, an magnesium alloy, titanium, a titanium alloy, steel, stainless steel or high-grade steel. The housing part has at least one opening through which at least one conductor, in particular an essentially pin-shaped conductor, embedded in a glass or glass ceramic material, is guided. The base body is, for example, an essentially annular-shaped base body and is hermetically sealed with the housing part such that the helium leakage rate is smaller than 1*10−8 mbar l/sec.
摘要:
A feed-through has a base body, for example in the form of a disk-shaped metal part. The base body includes at least one opening through which at least one conductor, for example an essentially pin-shaped conductor, embedded in a glass or glass ceramic material, is guided. The base body includes a material having a low melting point, such as a light metal, and the glass or glass ceramic material is selected in such a manner that the melting temperature thereof is lower than the melting temperature of the material of the base body.

Thin glass elements with improved edge strength are provided—from a sheet glass element that has two opposite parallel faces and an edge connecting the faces. The sheet glass element has a thickness of at most 700 μm. At least a portion of the edge is defined by an edge surface portion that is convexly curved, so that at least one of the faces merges into the edge surface portion, wherein a curved arc of the edge surface portion has a length that is at least 1/30 of the thickness of the sheet glass element. In the region of the convex curvature, the edge surface portion has indentations in the form of furrows.
