摘要：
The present invention relates to a light emitting device 100 which employs light sources 102 having a narrow or limited light intensity distribution, and which device is arranged for redistributing the light from the light sources and outputting a light with a broader spatial light intensity distribution via a circumferential light output surface 115 arranged on a funnel-shaped light output portion 112. The light emitting device further comprises a light mixing portion 120 for mixing the light emitted from the light sources 112 before entering into the light output portion 112.
