Abstract: An LED-illuminant includes a plurality of LED arranged on a corresponding plurality of supports each support having an angled support section. The angled support sections being adjacent to one another to form angled surfaces of a polyhedron. The heat of each LED is respectively dissipated from the angled support section to the rest of the support.

Abstract: A light shade is presented for a modular lighting system, such as for example the Occhio® system of the applicant, with a coupling element for connection with a lamp support element, an at least translucent outer shade and a screen with zones of differing light transmittance within the outer shade, whereby the outer shade and the screen are each connected detachably and therefore optionally interchangeably with the coupling element.

Abstract: An LED-illuminant comprises a plurality of angled supports (1.i). Thereby the angled support sections (2.i) of the supports (1.i) are adjacent. The solid angles of the surfaces of the angled support sections (2.i) substantially correspond to different solid angles of a polyhedron. The LED-element further comprises a plurality of LED-elements (4.i), which are arranged on the angled support sections (2.i), wherein the heat of the single LED-elements (4.i) is respectively dissipated starting from the angled support section (2.i) via the rest of the support (3.i).
