Abstract:
A supplementary lighting device comprising:an electroluminescent lighting element having a light intensity; a control system coupled to said electroluminescent lighting element, wherein said control system varies the light intensity of said electroluminescent lighting element; a user-adjustable dimmer coupled to said control system, wherein said dimmer includes a dimmer control and user adjustment of said dimmer control causes said control system to vary the light intensity of said electroluminescent lighting element; electrical connection blades, wherein the supplementary lighting device is coupled to a standard alternating current outlet through said electrical connection blades; and a light sensor coupled to said control system and disposed in the device so as to detect light emitted from said electroluminescent lighting element, wherein said control system varies the light intensity of said electroluminescent element so that said control system receives an input from said light sensor which effectively matches a pre-set level. wherein said user-adjustable dimmer includes a mechanical dimmer element positioned to optically and/or mechanically adjust the amount of light which is detected by said light sensor from said electroluminescent lighting element.
