摘要 |
A lighting device includes a radiation source that emits primary radiation in the wavelength range of 300 nm to 570 nm, a first phosphor arranged in a beam path of the primary radiation source that converts at least part of the primary radiation into secondary radiation in an orange to red wavelength range of 570 nm to 800 nm, and filter particles arranged in a beam path of the secondary radiation that absorb at least part of the secondary radiation. |
