Abstract

An optoelectronic component device includes a first group of optoelectronic components including at least one first optoelectronic component, wherein the at least one first optoelectronic component provides electromagnetic radiation of a first color valence, a second group of optoelectronic components including at least one second optoelectronic component, wherein the at least one second optoelectronic component provides electromagnetic radiation of a second color valence, and a phase dimmer, wherein the phase dimmer is designed in such a way that a first operating mode and a second operating mode are provided, wherein the phase dimmer actuates the first and the second group of optoelectronic components in such a way that, in the first operating mode, a first array of optoelectronic components of the optoelectronic component device is energized and, in the second operating mode, a second array of optoelectronic components of the optoelectronic component device is energized.

First claim

The invention claimed is:

1. An optoelectronic component device, comprising:
a first group of optoelectronic components comprising at least one first optoelectronic component, wherein the at least one first optoelectronic component is designed to provide electromagnetic radiation of a first color valence;
a second group of optoelectronic components comprising at least one second optoelectronic component, wherein the at least one second optoelectronic component is designed to provide electromagnetic radiation of a second color valence; and
a phase dimmer,
wherein the phase dimmer is designed such that a first operating mode with a first degree of dimming and a second operating mode with a second degree of dimming are provided,
wherein the phase dimmer actuates the first group of optoelectronic components and the second group of optoelectronic components such that, in the first operating mode, a first array of optoelectronic components of the optoelectronic component device is energized and, in the second operating mode, a second array of optoelectronic components of the optoelectronic component device is energized;
wherein, with respect to the total intensity of the electromagnetic radiation provided of the optoelectronic component device, the proportion of electromagnetic radiation of the first color valence is less in the first operating mode than in the second operating mode and the proportion of the electromagnetic radiation of the second color valence is greater in the first operating mode than in the second operating mode.

2. The optoelectronic component device as claimed in claim 1 ,
wherein the phase dimmer is designed for the phase gating control and/or phase chopping control of the optoelectronic components.

3. The optoelectronic component device as claimed in claim 1 ,
wherein the first group of optoelectronic components has at least one optoelectronic component more or fewer than the second group of optoelectronic components.

4. The optoelectronic component device as claimed in claim 1 ,
