| 摘要 |
The present invention relates to an illuminating device (1), comprising a pump radiation source (2) for emitting pump radiation as a beam (4), a phosphor element (22) and a lens system (3, 5) disposed between the pump radiation source and the phosphor element (2, 22); the lens system has a focal point, at which the phosphor element (22) is arranged, wherein a lens (5) of the lens system (3, 5) has a scattering means (26) which passes through the pump beam (4) and is thereby expanded, so that the pump beam (4) falls around a focal point (27) in an expanded manner onto the phosphor element. |
