The semiconductor-illuminant has a semiconductor-lighting unit (26,28), illuminated by tension admission, and a substrate (12) which is permeable for the light produced by the semiconductor-lighting unit. The substrate comprises a glass material or a crystal material which is aluminum oxide. The substrate has a thickness of approximately 0.1 millimeter to approximately 1 millimeter, preferably from approximately 0.1 millimeter to approximately 0.5 millimeter, again preferably from approximately 0.2 millimeter to approximately 0.4 millimeter. |
