Claim:
1. An apparatus comprising a mount and a plurality of LED light scattering apparatuses, each LED light scattering apparatus comprising a body, said body comprising a substantially hollow spherical cavity including a light entry port arranged to receive visible light from an LED mounted outside the cavity, a light exit port located opposite the entry port and through which the LED light exits the cavity for analysis, and a baffle located in a central region of the cavity in a direct optical path between the entry port and the exit port to interrupt the passage of visible LED light between the entry and exit ports, wherein each LED light scattering apparatus further comprises a resilient member which is caused to contract by movement of the LED light scattering apparatus towards the LED, and wherein the body of each LED light scattering apparatus is mounted to the mount and the bodies are all independently moveable with respect to the mount against forces exerted by the corresponding plurality of resilient members.
