| 摘要 |
The invention relates to a lighting device (1), comprising a pump radiation unit (2) and a luminescent element (9) arranged at a distance therefrom, wherein a pump beam (4) is guided from the pump radiation unit (2) to the luminescent element (9) by means of a lens (7) between the pump radiation unit (2) and the luminescent element (9), which lens focuses the pump beam (4), wherein a scattering element (8), which the pump beam (4) passes through, the pump beam thus being expanded, is arranged between the pump radiation unit (2) and the luminescent element (9). |
