发明名称 DIFFUSELY RADIATING LED LIGHT SYSTEM
摘要 A lighting device (7) for illuminating objects, the lighting device comprising: a plurality of light emitting diodes (1) wherein at least one of the plurality of light emitting diodes is adapted to generate light having a spectrum different from a spectrum of light generated by another light emitting diode of said plurality of light emitting diodes; and a chamber (8) comprising a first reflective surface (3a) and an opening (5) for allowing light to exit said chamber, said opening having a periphery, wherein the plurality of light emitting diodes (1) are positioned along the periphery of said opening. The opening (5) has a centre point defined as the centroid of said opening, and that said plurality of light emitting diodes are positioned along a limited portion of the periphery of said opening, wherein an angular distance between any two light emitting diodes of said lighting device relative the centre point of the opening is smaller than 135 degrees and said first reflective surface (3a) is a diffuse reflective surface.
