    • The invention relates to a lighting device comprising a light source (1) that emits incoherent light with a total radiation power P and has a radiation-emitting area (S) divided into a plurality of subareas (Si), wherein assigned to each subarea (Si) is a light ray (2) having a radiation power Pi and the sum of the radiation powers Pi is equal to the total radiation power P, and disposed after said light source (1) is an optical element (4) having a decoupling surface (5) and a total reflection angle (θc) assigned to said decoupling surface (5), said decoupling surface (5) being shaped so that at least for a portion of said light rays (2) the angle (α) of incidence on said decoupling surface (5) is smaller than the total reflection angle (θc), and the radiation power of said light rays collectively is greater than a predetermined fraction, equal to at least 50%, of the total radiation power P.
    • 本发明涉及一种照明装置,其包括发射具有总辐射功率P的非相干光的光源(1),并具有分成多个子区域(Si)的辐射发射区域(S),其中分配给每个子区域 Si)是具有辐射功率Pi的光线(2),并且辐射功率Pi的总和等于总辐射功率P,并且设置在所述光源(1)之后是具有去耦的光学元件(4) 表面(5)和分配给所述去耦表面(5)的全反射角(& t; c),所述去耦表面(5)被成形为使得至少对于所述光线(2)的一部分角度(α) 所述去耦表面(5)上的入射角小于全反射角(& C),并且所述光线的辐射功率总体上大于等于总辐射功率的至少50%的预定分数 P.
