PHOTOLUMINESCENT (PL) APPLICATIONS ON MOVEABLE EQUIPMENT

摘要

An equipment article and method of illuminating equipment articles in low light conditions. The equipment article includes a rotatable element and a photoluminescent application to a surface of the rotatable element. The photoluminescent application includes a plurality of strontium aluminate phosphor crystals. 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. The method of illuminating equipment articles in low light conditions illuminates the articles by the exhibited luminance.
