Problems solved by technology

Segmentation has so far not been possible with satisfactory quality
Separation by means of lasers can lead to blackening of the components and thus a loss of brightness of the LEDs, sawing does not offer the possibility of realizing cutouts in the components, and water cutting leads to poor edge quality of the wavelength conversion components

Embodiment Construction

[0061] In the exemplary embodiment and the figures, identical or identically acting components can each be provided with the same reference numerals. The shown elements and their mutual size relations are not to be regarded as true to scale; rather, they may be shown with exaggerated or exaggerated dimensions for better illustration and / or for better understanding. Identify individual elements such as layers, components, devices, and regions.

[0062] Figure 1a A schematic side view of an optoelectronic component with a semiconductor chip 2 and a wavelength conversion element 10 is shown. The wavelength converting element 10 is arranged by means of the first surface 10 a on a semiconductor chip which in turn is arranged on the carrier 1 . The semiconductor chip 2 and the wavelength converting element 10 are surrounded by an encapsulation 5 which is flush with the second surface 10b of the wavelength converting element. The wavelength conversion element 10 has a cutout 11 th...

Abstract

A method is proposed for producing a wavelength converting element (10), wherein a wavelength converting layer (100) is provided, the surface of the wavelength converting layer is treated with a plasma (50) and the wavelength converting layer is punched out. Furthermore, a wavelength-converting layer and an optoelectronic component having a wavelength-converting layer are proposed.

Description

technical field [0001] The invention relates to a method for manufacturing a wavelength converting element, a wavelength converting element and a device comprising the wavelength converting element. Background technique [0002] Light-emitting diodes (LEDs) generate light in a narrow wavelength range through which generally a monochromatic luminous impression is produced. In order to obtain a polychromatic or mixed-color luminous impression, pigments are usually arranged downstream of the LEDs, which partially convert the light emitted by the LEDs into light having other wavelengths. Thus, by superimposing the converted light with the light originally emitted by the LED, a wider wavelength spectrum can be obtained which can lead to a polychromatic or mixed-color luminous impression. [0003] In this case, wavelength-converting pigments are usually embedded in wavelength-converting layers which have to be divided into wavelength-converting elements in order to be able to be ...
