LIGHTING DEVICE AND LUMINAIRE |
摘要 |
Disclosed is a lighting device including a reflective element (10) comprising a reflective conical central section (12) having a conic constant in the range of −0.7 to −1.3; and an annular array of reflective ellipsoid surfaces (14, 14′) extending radially from said reflective conical central section, each reflective ellipsoid surface creating a first focal point (16) inside the reflective conical central section and a second focal point. The lighting device further comprises a solid state lighting element (20, 20′) located at the second focal point of each of said reflective ellipsoid surfaces and arranged to emit light towards said reflective ellipsoid surface; and an exit window (30) opposite said reflective conical central section. A luminaire including such a lighting device is also disclosed. |
