Claim:
1. A lighting device comprising: at least a first light emitter; at least a first heat transfer element having an annular outer region, an inner space defined by and completely surrounded by the outer region, a first plane and a second plane, the first light emitter in the inner space; and a plurality of heat dissipation elements comprising at least a first heat dissipation element and a second heat dissipation element, each heat dissipation element having at least a first region and a second region, the first region in contact with the first heat transfer element, the second region closer to the first light emitter than the first region is, the first heat dissipation element having a first dissipation element first region and a first dissipation element second region, the first dissipation element first region in contact with the first heat transfer element, the first dissipation element second region closer to the first light emitter than the first dissipation element first region is, the second heat dissipation element having a second dissipation element first region and a second dissipation clement second region, the second dissipation element first region in contact with the first heat transfer element, the second dissipation element second region closer to the first light emitter than the second dissipation element first region is, the second dissipation element second region closer to the first light emitter than the first dissipation element second region is, the first heat dissipation element attached only to the first heat transfer element at only the annular outer region of the first heat transfer element, at least the first heat dissipation element extending from the outer region into the inner space, the first light emitter thermally coupled to the first heat transfer element.
