Abstract
The present invention is a solar powered flat, electroluminescent lamp night light adapted to be placed upon or attached to a window sill. The night light has a vertical upper portion which retains a solar cell unit that faces toward the window when the night light is placed on the window sill. The night light also has a horizontal middle section which is either adapted to rest upon a window sill, thereby balancing the night light in place, or adapted to attach the night light directly to the a portion of the window sill. The night light also a vertical lower portion which houses a flat, electroluminescent sheet light source. When the night light is placed upon a window sill, the flat, electroluminescent sheet light source faces into the room and illuminates the area of interest. The solar cell unit is configured to receive sunlight and convey electrical current to the flat, electroluminescent sheet light source and to an energy retaining device. The device could also have a set of sensors which determines if the night light should be on or off. A switch could also be provided for manual operation.
