摘要
The invention relates to an apparatus for measuring light and a luminaire comprising the apparatus. The apparatus measures light from a first light emitting device located in a first position and comprises a light transmissive device having at least three surfaces: a first surface, a second surface and a third surface; and a photo sensor. The first surface is arranged for incoming light from the first position, the second surface is arranged for reflecting incident light within the light transmissive device and the third surface is arranged such that outgoing light incides onto the photo sensor.
