| 发明名称 | Lighting device with pump light source and phosphor arrangement | ||
| 摘要 | 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. | ||

| 主权项 | 1. A lighting device, comprising: 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 comprises at least one phosphor which can be irradiated with at least one of the reflected part and 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, wherein the light control element has a front side and a rear side; and wherein the front side comprises a region which is designed to be reflective for the pump light. | ||
