Abstract

The invention relates to a method for measuring a light radiation (300) emitted by a light-emitting diode (210). In the method, an end (121) of an optical fiber (120) which is connected to a measuring device (130) is irradiated with the light radiation (300), which is emitted by the light-emitting diode (210), through an optical device (140), so that a portion of the light radiation (300) is coupled into the optical fiber (120) and is guided to the measuring device (130). The optical device (140) causes the light radiation (300) passing through the optical device (140) to be emitted in diffuse form in the direction of the end (121) of the optical fiber (120). The invention also relates to an apparatus (100) for measuring a light radiation (300) emitted by a light-emitting diode (210).
