Embodiment Construction

[0112] according to Figure 1a The converter element 1 shown in FIG. 1 shows a thin plate 2 made of mineral glass, for example borate glass. The sheet is, for example, 200 μm thick. Arranged in the thin plate are first converter particles 3 with a diameter of 30 μm. Deviations of up to 10% in diameter are possible. The first converter particles are completely embedded in the mineral glass of the thin plate 2 and are in direct mechanical contact with this mineral glass. The first converter particle 3 consists of a core 3b and an outer shell 3a. The molecular formula of core 3b by nitrogenation is M 2 SiN 8 : EU 2+ (where M=Ca, Sr, Ba) or mixtures thereof constitute and emit light in the red wavelength range of the electromagnetic spectrum. Housing 3a is for example made of SiO 2 constitute. Such as Figure 1a As shown in , the sheet 2 has a first major surface 2a and a second major surface 2b. The first main surface 2 a has a smaller distance from the first converter...

Abstract

A converter element is specified which has a thin plate comprising inorganic glass and which has first converter particles. The first converter particle has a shell and a core. The shell includes an inorganic material, and the core includes a nitrided oxynitrided luminophore. The first converter particles are arranged on and / or in the sheet.

Description

technical field [0001] The invention relates to a conversion element, a method for producing the conversion element and an optoelectronic component comprising the conversion element. Background technique [0002] Optoelectronic components, such as light-emitting diodes (LEDs), usually have a conversion element with a luminescent substance. The luminophore converts the radiation emitted by the radiation source into radiation having a modified, for example longer, wavelength. In this case, heat is generated in addition to the emitted modified radiation. Conventional conversion elements usually have silicone as the matrix for the luminophore. However, silicones have insufficient heat dissipation of the heat generated by the illuminants. This results in overheating in the conversion element, which leads to a reduction in the luminous intensity and a change in the color position and to an early selection of the LED. Contents of the invention [0003] It is an object of at l...
