Abstract
The invention relates to an optical arrangement including LED lighting elements arranged on a support surface. An optical axis X extends from the support surface. A first collimator unit includes at least one support element and first collimator elements. The support element is supported on the support surface between at least two of the LED lighting elements. The first collimator elements are arranged in front of the LED lighting elements in the direction of the optical axis X to collimate light emitted from the LED lighting elements. A second collimator unit is arranged in front of the first collimator unit in the direction of the optical axis X. The second collimator unit includes second collimator elements arranged in front of the first collimator elements to collimate light emitted therefrom.
