Abstract
Disclosed herein are methods, systems, and devices for providing illumination in harsh environments having airborne floating debris. In one embodiment, an illumination device includes an enclosure having a pinhole and a light source positioned within the enclosure. The light source is configured to provide illumination external of the enclosure via the pinhole. The enclosure is configured for providing a first gas flow exiting the pinhole. The first gas flow prevents any of the airborne floating debris from entering the pinhole. In another embodiment, a method is disclosed. The method includes providing illumination via a pinhole of an enclosure comprising a light source and providing a first gas flow exiting the pinhole. The first gas flow prevents float airborne debris from entering the pinhole.
