A conversion material for a white or colored light source is provided. The material includes a matrix glass that, as bulk material, for a thickness of about 1 mm, has a pure transmission of greater than 80% in the wavelength region from 350 to 800 nm and in the region in which the primary light source emits light, wherein the sum of transmission and reflection of the sintered matrix glass without luminophore is at least greater than 80% in the spectral region from 350 nm to 800 nm and in the spectral region in which the primary light source emits light.

Conversion material for white or colored light source, method of production, and light source having the conversion material

The present disclosure relates to a bonding glass which has improved water resistance and has a coefficient of thermal expansion &#x3b1;(25-300) of from 14&#xb7;10Kto 17&#xb7;10K, comprising, in mol % on an oxide basis, 5-7 of BO, 10-14 of AlO, 36-43 of PO, 15-22 of NaO, 12.5-20 of KO, 2-6 of BiOand &#x3e;0-6 of R oxide, where R oxide is an oxide selected from the group consisting of MnOand SiOand SnOand TaOand NbOand FeOand GeOand CaO. The bonding glass is free of PbO except for, at most, impurities. The bonding glass may have a glass transition temperature Tg of from 390&#xb0; C. to 430&#xb0; C. The present disclosure also relates to uses of this bonding glass.

High-expansion bonding glass having improved water resistance and uses thereof

An electric energy production device or an electric energy storage device including a housing and a feed-through. The feed-through includes at least one body which has at least one opening through which the at least one conductor in an electrically insulating material is fed. The insulating material has a layer structure of at least two layers wherein a top layer being arranged towards the outside of the electric energy production device or the electric energy storage device consists of a sealing glass and an inner layer one of comprises and consists of a further glass material or glass ceramic material. The electrically insulated material is bonded with at least one of the base body and the conductor, wherein the sealing glass one of includes and consists of titanium glass.

Feedthrough

A feed-through includes at least one main body which has at least one opening through which at least one conductor in an electrically insulating material comprising or consisting of a sealing glass is fed, wherein the main body comprises or consists of a light metal and/or a light metal alloy, with an integral bond being formed between the light metal and/or the conductor and the sealing glass, wherein the sealing glass comprises or consists of a titanate glass and has only a small phosphate proportion.

The invention relates to a conversion material, in particular for a white or colored light source comprising a semiconductor light source as primary light source, comprising a matrix glass that, as bulk material, for a thickness d of about 1 mm, has a pure transmission &#x3c4;of greater than 80% in the wavelength region from 350 to 800 nm and in the region in which the primary light source emits light, wherein the sum of transmission and reflection of the sintered matrix glass without luminophore is at least greater than 80% in the spectral region from 350 nm to 800 nm and in the spectral region in which the primary light source emits light.
