Lighting device with perpetually clean lens |
摘要 |
An outdoor lighting fixture or luminaire includes an enclosure having within it a light source for projecting light through an opening in the enclosure and a motor train for slowly moving a transparent plastic film across the opening and over the light emitting surface of the light source, thereby preventing the light emitting surface or lens from becoming dirty over time.
