Abstract:
In various embodiments, a lighting device is provided. The lighting device may include: a pump light source; a phosphor arrangement; and a light control element arranged between the pump light source and the phosphor arrangement; wherein the light control element is configured to split the pump light beam into a reflected part and a transmitted part and for controlling the ratio between reflected part and transmitted part; and wherein the phosphor arrangement includes at least one phosphor which can be irradiated with the reflected part and/or transmitted part of the pump light of the pump light source and emits said pump light again at least partly in a wavelength-converted fashion.
