Light device deriving condition of storage circuit

A device for providing power to a light arrangement for emitting light, the light arrangement being configured to be in a current conducting state or in a current blocking state, the device further comprising:

• a storage circuit coupled to the light arrangement, the storage circuit comprising a capacitor and a resistor located in parallel to the capacitance,
• a first determination circuit configured to determine whether the light arrangement is in the current conducting state or in the current blocking state,
• a second determination circuit configured to determine in the current blocking state of the light arrangement points of a discharging curve of the storage circuit, and
• a derivation circuit configured to derive from the discharging curve a condition of the storage circuit;
• wherein the device further comprises:
• a switch circuit configured to switch an element in parallel to the capacitor, and wherein
• the points of the discharging curve of the storage circuit comprise first points of a first discharging curve of the storage circuit determined for the capacitor being disconnected from the element and discharging via the resistor without the element, and
• the points of the discharging curve of the storage circuit comprise second points of a second discharging curve of the storage circuit determined for the capacitor being connected to the element and discharging via both the resistor and the element.
