Abstract: A lighting device for emitting a red total radiation may be configured such that the lighting device has a semiconductor layer sequence configured to emit electromagnetic primary radiation. A conversion element may include a first fluorescent material of the formula Sr[Al2Li2O2N2]:Eu, crystallized in the tetragonal space group P42/m. The first fluorescent material may at least partially convert the electromagnetic primary radiation into an electromagnetic secondary radiation in the red region of the electromagnetic spectrum. The conversion element may include a second fluorescent material to at least partially convert the electromagnetic primary radiation into an electromagnetic secondary radiation in the red region of the electromagnetic spectrum and/or the lighting device may include a mirror or filter arranged above the conversion element.
