Abstract
A lighting apparatus for securing to differently dimensioned objects, in particular mobile devices, is intended to be provided. For this purpose, a lighting apparatus comprising an illuminant and a holding element is proposed, wherein the illuminant is secured to a first end section of a bistable element and the holding element is secured to a second end section of the bistable element, said second end section being situated opposite the first end section. The bistable element is rolled out in a first stable state, such that the illuminant is at a maximum distance from the holding element. The bistable element is rolled together in a second stable state. The lighting apparatus is clampable to the mobile device by spring force of the bistable element.
