Abstract: Disclosed is a lighting device (100) comprising a plurality of solid state lighting (SSL) elements (20) such as LEDs that can be manufactured in a cost-effective manner and that emulates the appearance of an incandescent lighting device. The lighting device has a luminous arrangement comprising opposing tubular portions (12, 14) in between which strip-shaped portions (16) that carry the SSL elements radially extend. The luminous arrangement is mounted on a support structure (30) fitted inside a transmissive body (1 10) of the lighting device. A luminaire including the lighting device, a method of manufacturing the luminous arrangement and a method of manufacturing the lighting device are also disclosed.

Abstract: 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.

Abstract: 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.

Abstract: 9A light emitting diode (LED) lighting device includes a concave mirror and a convex mirror having a diameter less than a diameter of the concave mirror. The convex mirror is positioned to face the concave mirror and is fixed to the concave mirror. An LED array is fixed to the concave mirror between the concave mirror and the convex mirror. The LED array faces the convex mirror such that light emitted by the LED array reflects off of the convex mirror. A power supply is provided for powering the LED array. Light emitted by the LED array is reflected from the convex mirror onto the concave mirror, and then reflected by the concave mirror to exit the lighting device.
