Abstract
The present invention provides methods and systems for moveable pieces of equipment comprising a passively charged photoluminescent material to improve visibility of the equipment in low light conditions. This moveable piece of equipment may be a piece of ground support equipment such as that used in support of an operation. Further, these operations may include, for example, nautical operations (e.g., Naval operations or ocean-going cargo transportation), construction of a structure (e.g., building construction), aviation (i.e., flight) operations (e.g., in support of an airport), transportation of goods (e.g., via rail or truck), drilling operations (e.g., drilling for oil, water, gas or explosives), mining operations, oil processing (refinery) operations etc.
Claims34
A moveable piece of equipment for use in supporting a military operation, the moveable piece of equipment comprising:
- a photoluminescent application to a surface of the moveable piece of equipment comprising a plurality of strontium aluminate phosphor crystals, wherein the photoluminescent application exhibits a luminance of greater than or equal to 0.05 millicandela per square meter (mcd/m2) for a period of at least 4000 minutes.
A method to improve visibility in low light conditions of a piece of moveable equipment used in support of an operation, the method comprising:
- applying a photoluminescent material to a moveable piece of equipment, the photoluminescent material comprising a plurality of strontium aluminate phosphor crystals, wherein the photoluminescent application exhibits a luminance of greater than or equal to 0.05 millicandela per square meter (mcd/m2) for a period of at least 4000 minutes.
