• at least one first LED configured to emit light of a first color;
• at least one second LED configured to emit light of a second color different from the first color;
• a light mixing device arranged to receive and mix light from the at least one first LED and the at least one second LED and to emit the mixed light,
• wherein the light mixing device comprises:
• a body made of a material having a higher refractive index than air and comprising scattering particles distributed within the material;
• wherein,
• the outer surface of the body comprises a light incident area and a light emergent area, the light incident area being arranged to receive the light from the at least one first LED and the at least one second LED;
• and
• the material and the scattering particles are arranged for mixing the received light and emitting the mixed light from the light emergent area,
• wherein the light emergent area is smaller than the light incident area.
