CN106030206A 具有初级光源和发光材料体积部的照明设备 有权

具有初级光源和发光材料体积部的照明设备
Abstract:
照明设备(1，W)具有：至少一个初级光源(2)；用于至少部分地将初级光(P)转换成次级光(S)的、与所述初级光源间隔开的发光材料体积部(4)；用于检测借助至少一个初级光源(P)产生的光(P，S)的至少一个光传感器(5，7)和用于确定发光材料体积部(4)的损坏情况的评估装置(9)，其中照明设备(1，W)具有用于辐照发光材料体积部(4)的至少一个附加光源(Z1，Z2，Z3)并且构建用于：在初级光源(2)被切断的情况下运行至少一个附加光源(Z1，Z2，Z3)、至少一个光传感器(5，7)和评估装置(9)。一种用于确定照明设备(1，W)的发光材料体积部(4)的损坏情况的方法，其中所述方法具有至少下列步骤：仅借助附加光源(Z1，Z2，Z3)辐照发光材料体积部(4)并且基于至少一个光传感器(5，7)的传感器数据确定发光材料体积部(4)的损坏情况。
Abstract(English):

The lighting device (1, W) comprises at least one primary light source (2), a phosphor volume (4) spaced apart therefrom and serving for at least partly converting the primary light (P) into secondary light (S), at least one light sensor (5, 7) for detecting light (P, S) generated by means of the at least one primary light source (2), and an evaluation device (9) for determining a case of damage to the phosphor volume (4), wherein the lighting device (1, W) comprises at least one additional light source (Z1, Z2, Z3) for irradiating the phosphor volume (4) and is designed to operate the at least one additional light source (Z1, Z2, Z3), the at least one light sensor (5, 7) and the evaluation device (9) with primary light source (2) switched off. A method serves for determining a case of damage to a phosphor volume (4) of a lighting device (1, W), wherein the method comprises at least the following steps: irradiating a phosphor volume (4) only by means of the additional light source (Z1, Z2, Z3) and determining a case of damage to the phosphor volume (4) on the basis of sensor data of at least one light sensor (5, 7).
