The invention relates to a lighting device (1), comprising: a radiation source (2) that emits primary radiation in the wavelength range between 300 nm to 570 nm, a first luminescent substance (3), which is arranged in the beam path of the primary radiation source (2) and converts at least part of the primary radiation into secondary radiation in an orange to red wavelength range of 570 nm to 800 nm, preferably 580 nm to 650 nm, further preferably 590 nm to 640 nm, and filter particles (4), which are arranged in the beam path of the secondary radiation and absorb at least part of the secondary radiation. Such a lighting device can have higher color purities and higher intensities of the emitted radiation in relation to traditional lighting devices. |
