Abstract

There is provided a battery powered lighting system having illuminating units and a battery module with rechargeable batteries for providing electrical power to the illuminating units. A temperature sensor is arranged to measure a temperature of the battery pack. A charger and discharger are arranged to (dis)charge the battery module, where discharging means powering the illumination units. A control system is arranged to adjust a lighting profile using measurements received from the temperature sensor. The adjusted lighting profile will assures that the temperature of said battery module stays within a predefined temperature range, and in particular above a predefined temperature. This will extend the life time of the batteries.
