Lighting device having uninterruptible illumination and external power supply function

The present invention provides a lighting device having uninterruptible illumination and external power supply function, in which the lighting device (L100) is combined with an energy storing/discharging device (ESD100) thereby providing an uninterruptible illumination function and supplying uninterruptable AC or DC power to the exterior during power blackout, a controller assembly (1000) is integrated with an operation device (OP100), an external power supply interface device (C100), an electric-driven lighting device (L100), a public power and/or solar power and/or wind power generation source (PS100), and an energy storing/discharging device (EDS100), thereby capable of providing the uninterruptible illumination function and supplying uninterruptable AC or DC power to the exterior during power blackout.
