Abstract: This lighting system improves the illumination of enclosed spaces by reducing undesirable shadows. Elongated curved reflective surfaces at the upper periphery of the illuminated space reflect light from a central source to the activity area. Light arriving at the activity area from many directions softens or eliminates shadows. Appropriate lighting contrast may be selected at installation and maintained by simple adjustments in response to changes in layout, furnishings, and activities conducted in the illuminated area. Contrast may be controlled as needed by varying the ratio of light reflected from the periphery to that proceeding directly from the central source to the activity area. A smaller number of efficient, powerful light sources lowers power consumption, reduces fixture installation and wiring costs, and diminishes maintenance labor compared to conventional lighting systems.
