ABSTRACT:
Phosphorescent materials are incorporated into the composition and construction of various components of a skylight. The resulting skylight absorbs light through these relevant components in the presence of external light while emitting phosphorescence, or delayed luminescence, in the absence of external light. The light-storage effects of the phosphorescent components offer the added advantage of reducing sensitivity of internal illumination intensity to abrupt variations in external light intensity. Using commercially-available high-performance phosphorescent materials, such skylight components are manufactured safely and cost-effectively. The resulting skylights offer simple passive interior illumination for hours after daylight ceases.
