A radiation emitting device may have a plurality of emitters and a plurality of optical elements. The emitters may be arranged along a first emitter direction at a first average emitter spacing AEand along a second emitter direction extending obliquely or perpendicularly to the first emitter direction at a second average emitter spacing AE. The optical elements may be arranged along a first optics direction at a first average optics spacing AOand along a second optics direction extending obliquely or perpendicularly to the first optics direction at a second average optics spacing AO

Uniformly illuminating radiation emitting device and method of manufacture

A method for operating an optoelectronic semiconductor device. The semiconductor device includes a first optoelectronic semiconductor chip for generating, for example, blue light, an optional second optoelectronic semiconductor chip for generating, for example, green light, and a third optoelectronic semiconductor chip for generating, for example, red light. The semiconductor device also includes a driver unit which supplies the semiconductor chips with current during operation. The third semiconductor chip is operated on the basis of a temperature-brightness characteristic curve stored in the driver unit. The temperature-brightness characteristic curve is configured for a minimum color location deviation over an intended operating temperature range, relative to at least one reference color location.

Method for operating an optoelectronic semiconductor device and optoelectronic semiconductor device

A light-emitting component is disclosed. In an embodiment a light-emitting component includes at least four light sources configured to emit light of different wavelength ranges in pairs and a control device configured to operate the light sources independently of one another in such a way that light from at least two of the light sources is mixed to form a mixed light and adjust an mvalue of the mixed light, wherein the at least four light sources include a first light source configured to emit electromagnetic radiation with a dominant wavelength of at most 450 nm, a second light source configured to emit electromagnetic radiation with a dominant wavelength of at least 480 nm and at most 520 nm or a dominant wavelength of at least 455 nm and at most 470 nm, a third light source configured to emit electromagnetic radiation in a spectral range of green light, and a fourth light source configured to emit electromagnetic radiation in a spectral range of yellow and/or amber light.
