Abstract
A lens arrangement for an LED display device includes a lens. The lens has a first lens surface and an optical axis. The optical axis penetrates the first lens surface of the lens. Furthermore, the lens arrangement includes a transparent transition body, which is firmly coupled with the lens on the first lens surface, which is more temperature-resistant than the lens and which has an optical axis that is parallel to the optical axis of the lens.
