There is disclosed a lighting device of which the light sources and/or optical elements are hidden in a first cover state associated with a first light state. This enables an unobtrusive lighting system in the first cover state. In a second cover state associated with a second light state, optical elements, e.g. shutters or beam shaping elements, are switched, induced by the heat or the light flux generated by the light sources, such that the lighting system can function properly. |
