照明设备
摘要：
一种照明设备，包括有机发光二极管(1)(OLED)，有机发光二极管(1)(OLED)具有随着使用而变化的光输出，并具有照明/有效区域(2、3)，为了照明目的在所说照明/有效区域(2、3)处发射光；参考区域(4)，参考区域(4)充分地小于照明区域(2)，其中，参考区域(4)是没有连接至照明/有效区域(2、3)的隔离区域(4)；基底，参考区域(4)、照明/有效区域(2、3)位于所说基底上；驱动器(5)，驱动器(5)连接至参考区域(4)、照明/有效区域(2、3)，驱动器(5)具有测量电路(6)，测量电路(6)检测照明/有效区域(2、3)的至少一个有效值以及参考区域(4)的至少一个参考值；控制电路(7)，控制电路(7)对有效值和参考值进行比较并响应之产生校正信号以补偿照明区域(2)的光输出中的变化，其中控制电路(7)基于有效值和参考值计算用于照明区域(2)的校正信号。
摘要（英）：

An illumination device comprising an organic light-emitting diode (1) (OLED) having a light output that changes with use with an illumination/active area (2,3), where light is being emitted for an illumination purpose, a reference area (4) being substantially smaller than the illumination area (2), wherein the reference area (4) is an isolated area (4) not connected to the illumination/active area (2,3), a substrate, on which the reference area (4) and the illumination/active area (2,3) are located, a driver (5) connected to the illumination/active area (2,3) and the reference area (4), with a measurement circuit (6) detecting at least one active value of the illumination/active area (2,3) and at least one reference value of the reference area (4), a control circuit (7), which compares the active and the reference value and produces a correction signal in response thereto to compensate the changes in the light output of the illumination area (2), wherein the control circuit (7) calculates the correction signal for the illumination area (2) based on the active value and the reference value.
