Abstract
A supplementary lighting device with a replaceable electroluminescent light element is disclosed. A control system is provided to boost the light intensity of the electroluminescent light element. A light sensor is provided which detects light emitted from the electroluminescent lighting element and inputs this information to the control system. The control system automatically adjusts the intensity of the electroluminescent lighting element according to a pre-set value and the information from the light sensor. This allows for the electroluminescent lighting element to maintain a constant output despite the ageing of the electroluminescent lighting element. The pre-set value for the intensity of the electroluminescent lighting element can be adjusted by a user controlled dimmer. The dimmer varies the amount of light detected by the light sensor in order to increase or decrease the power provided by the control system to the electroluminescent lighting element.
