In various embodiments, an illumination apparatus is provided. The illumination apparatus includes a housing, in which at least one radiation source is fixed. A phosphor that is fastened to the housing is arranged downstream of the radiation source. The phosphor is connected to a crack detector, which is used for crack monitoring of the phosphor. A signal path is provided. The signal path connects the crack detector to an evaluation unit that is fixed to the housing. The signal path is formed by at least two contact pins and a flexible printed circuit board that is connected to the crack detector.

Illumination apparatus and headlamp

In various embodiments, an optical arrangement is provided. The optical arrangement includes a carrier plate, on which at least one light source is arranged, at least one optical element for directing the radiation of the at least one light source, and at least one sleeve, which is connected to the light source and is intended to hold the optical element. At least one of the sleeve is configured in such a way that the light source and the optical element are respectively arranged therein at least in sections, or the optical element can be positioned exactly with respect to the light source.

Optical arrangement and lamp

An arrangement with a multiplicity of optical semiconductor elements is disclosed. The semiconductor elements are respectively clamped against a semiconductor element carrier by way of a spring element. Additionally lying against the spring element is an optical element assigned to a respective semiconductor element, the spring element in this case being configured in such a way that it defines a fixed distance between the semiconductor element and the optical element.
