The invention proposes a lighting device, in particular an emergency lighting device. The lighting device includes a first housing (), a lighting means (), for example an LED arranged at the first housing () and an electronic circuitry accommodated in the first housing () for operating the lighting means (). A second housing () of the lighting device accommodates an energy storage means () such as a rechargeable battery, wherein the first housing () and the second housing () are arranged spaced apart. An interconnecting means () mechanically connects the first housing () and the second housing () in an elastic manner and also connects electrically the electronic circuitry and the energy storage means (). The interconnecting means () of the lighting device of a preferred embodiment comprises a cable which is overmoulded to provide compressive strength in an axial direction of the cable.

Lighting device

The invention relates to an operating device () for at least one light-emitting diode () having an input () for coupling to a DC bus () in order to receive a DC supply voltage. The operating device () has a configurable emergency light function. The operating device () is designed to produce, in the emergency light case, the LED currently for the at least one light-emitting diode () in dependence on how the emergency light function is configured.
