    • The light emission device (1) comprises a base substrate (2) and, preferably, three light-emitting diodes (3a, 3b, 3c), respectively associated with three primary colours and emitting a portion of their signal in the direction of the base substrate (2). The device (1) includes three chromatic photodetectors (7a, 7b, 7c) formed in the base substrate (2), constituting a semiconductor substrate, each chromatic photodetector being placed beneath an associated light-emitting diode (3a, 3b, 3c). Each chromatic photodetector (7a, 7b, 7c) comprises superposed first layers (9a, 9b, 9c), second layers (10a, 10b, 10c) and third layers (11a, 11b, 11c). The first layers (9a, 9b, 9c) and third layers (11a, 11b, 11c) have a first type of conductivity and the second layers (10a, 10b, 10c) have a second type of conductivity. The device (1) includes a control component (6), connected to the chromatic photodetectors (7a, 7b, 7c) and to the light-emitting diodes (3a, 3b, 3c), in order to control the overall colour of the light emitted by the device (1).
    • 发光装置(1)包括基底(2),优选地包括分别与三原色相结合的三个发光二极管(3a,3b,3c),并且在基底的方向上发射它们的一部分信号 基板(2)。 器件(1)包括形成在基底(2)中的三个彩色光电探测器(7a,7b,7c),构成半导体衬底,每个彩色光电探测器放置在相关联的发光二极管(3a,3b,3c)的下方。 每个彩色光电检测器(7a,7b,7c)包括叠置的第一层(9a,9b,9c),第二层(10a,10b,10c)和第三层(11a,11b,11c)。 第一层(9a,9b,9c)和第三层(11a,11b,11c)具有第一类型的导电性,第二层(10a,10b,10c)具有第二类导电性。 装置(1)包括连接到彩色光电检测器(7a,7b,7c)和发光二极管(3a,3b,3c)的控制部件(6),以便控制光的整体颜色 由设备(1)发射。
