    • A luminous unit (1) for an optical recording device (13) comprising a light source (2) for generating radiation and a partly reflective element, which is disposed downstream of the light source (2) in a main emission direction (H) and subdivides a space into a first half-space facing the light source (2) and a second half-space remote from the light source (2), wherein the partly reflective element at least partly transmits the radiation coming from the light source (2) from the first half-space and at least partly reflects the external radiation coming from an opposite direction from the second half-space.
    • 一种用于光学记录装置(13)的发光单元(1),包括用于产生辐射的光源(2)和部分反射元件,所述光源单元设置在所述光源(2)的主发射方向(H)的下游,以及 将空间细分成面向光源(2)的第一半空间和远离光源(2)的第二半空间,其中部分反射元件至少部分透射来自光源(2)的辐射, 并且至少部分地反映来自与第二半空间相反的方向的外部辐射。
