Embodiment Construction

[0018] Figures 1A to 1G Various method steps of an exemplary embodiment of the method are described, wherein a schematic partial cross-sectional view of the transparent base layer 1 and further layers already arranged thereon is shown in each case. Dimensional relationships, especially layer thickness relationships, are not to scale. In addition according to Figure 1A with 1B The method steps are optional and thus can be omitted; correspondingly can also be omitted in Figures 1C to 1F Layer 5 in . From this practical approach to Figure 1C Initially, the glass solder 2a that is not yet phosphorescent is deposited or coated in another way—either directly on the transparent base layer 1 or (as shown) previously applied to the base layer 1, which can On the selected scattering layer 5.

[0019] According to an improved scheme, the scattering layer 5 ( Figure 1A ) is first deposited directly on a (preferably planar and plane-parallel) transparent substrate 1 of substrate t...

Abstract

The invention relates to a method for producing a conversion element (10) for an optical and / or optoelectronic component, wherein the method comprises at least the following steps: a) providing a transparent substrate (1); b) applying a layer (2) that contains powdery glass solder; c) vitrifying the layer (2) by means of a first temperature treatment (TB1), whereby the glass solder (2a) of the layer (2) is vitrified and thus is converted into a transparent glass material (2b) having low natural coloring; d) applying a material containing luminescent substance to the layer (2); and e) performing a second temperature treatment (TB2), whereby the luminescent substance (4) of the material containing luminescent substance sinks into the glass material of the layer (2).

Description

technical field [0001] The invention relates to a method for producing a conversion element and to a conversion element. In combination with optical and / or optoelectronic components, the conversion element serves to change the spectrum and thus the perceived color perception of the electromagnetic radiation emitted by the element. For this purpose, the conversion element is mounted in front of the element, for example a light-emitting semiconductor chip, so that the radiation emitted by the component passes through the conversion element. The phosphors in the conversion element here adjust the color range and color temperature. Background technique [0002] Conventionally, matrix material and phosphor are mixed with one another during the production of the conversion element. Silicone resins are traditionally used as matrix material. Silicones are poor thermal conductors, so that during operation of the light-radiating component the phosphor is subjected to increased ther...
