Title A new lighting concept for better vision and judicious power consumption
Original title Neues Beleuchtungskonzept fŘr besseres Sehen und sinnvolle Energienutzung [in German]
Bibliographic information 1978, Vol.52, No.4, p.185-187. Illus. 7 ref.
Abstract The basic relations between reduction of contrast and reflected glare and the American ESI (Equivalent Sphere Illumination) method of evaluating lighting systems are set out. A new system of lighting is presented, combining ceiling-mounted units with a broad light distribution curve and supplementary local luminaires with an asymmetric light distribution curve having fluorescent tubes and adjustable mirrors. This dual component technique permits a reduction in general lighting, flexible adaptation of local lighting, optimum contrast conditions, and savings in electricity.
