LIGHTING DEVICE, LIGHTING KIT AND LUMINAIRE |
| 摘要 |
Disclosed is a lighting device comprising a solid state lighting element (20, 21, 101,102); a reflective arrangement (10) for reflecting luminous output of the solid state lighting element, the reflective arrangement comprising: a reflective conical central section (12) on a central axis of the lighting device; and an annular reflective body around the reflective conical central section, said body comprising an ellipsoid surface (14) having a first focal point lying inside the reflective conical central section and a second focal point, wherein the solid state lighting element is located at the second focal point; wherein the reflective conical central section (12) is movably mounted along said central axis. A lighting kit and luminaire including such a lighting device are also disclosed. |

1. A lighting device comprising:
a solid state lighting element; a reflective arrangement for reflecting luminous output of the solid state lighting element, the reflective arrangement comprising: a reflective conical central section on a central axis of the lighting device; and an annular reflective body around the reflective conical central section, said body comprising an ellipsoid surface having a first focal point lying inside the reflective conical central section and a second focal point, wherein the solid state lighting element is located at the second focal point; and wherein the reflective conical central section is movably mounted along said central axis;
wherein the annular reflective body comprises an annular array of reflective ellipsoid surfaces extending radially from said reflective conical central section, each reflective ellipsoid surface having a first focal point inside the reflective conical central section and a second focal point; and the lighting device comprises a plurality of solid state lighting elements, each solid state lighting element being located at a respective one of said second focal points, and arranged to emit light towards said reflective ellipsoid surface. |
