Abstract
The invention relates to a light-curing device, comprising a plurality of individual LED chips, each associated to a reflector, which LED chips are in particular each separately controllable and are arranged about a common central axis, in particular in each case at the same distance, and comprising reflection elements of the reflectors which adjoin one another, wherein the distance of the reflectors from one another is in each case substantially less, in particular less than a fifth, of the reflectors' diameter. The reflection elements () are arranged like a clover leaf and are part of a common reflector body () which separates the reflection elements (-) from one another by means of dividing walls (), and the reflector body () has externally on the reflection elements (-) reinforcing walls () which—in relation to each cone ()—lie opposite the central axis ().
