LIGHT-EMITTING DEVICE |
| 摘要 |
A light-emitting device is specified, said device comprising: a light-emitting semiconductor element (23) which emits greenish white light (10) during operation of the device, a filter element (4) which has a higher optical transmittance (11) in a spectral region of red light than in a spectral region of blue and green light, wherein the filter element (4) is arranged in such a way with respect to the light-emitting semiconductor element (23) that solely filtered light (12) which passes through the filter element (4) is emitted by the device during operation of the device, and the filtered light (12) is warm-white light. |
