Abstract
In various embodiments, a lighting device is provided. The lighting device includes at least one light source for emitting primary light, at least one phosphor body which is illuminatable by the primary light and is spaced apart from the at least one light source, and at least one light scattering body which is situated optically downstream of the phosphor body in a light propagation direction of the primary light that is uninfluenced by the phosphor body. The lighting device is designed in the case of an intact phosphor body to generate an illumination pattern by light generated by the phosphor body, and otherwise to generate a light emission pattern by light generated by the at least one light scattering body. The light emission pattern differs from the illumination pattern.
