The Lighting Design Objectives (LiDOs) procedure

摘要

This procedure is based on the concept that there is real advantage to be gained from changing the illumination metrics used for specifying, measuring and predicting lighting applications so that they relate to peoples' responses to visible effects of lighting in indoor applications. The currently used illumination metrics are directed towards providing for visibility, or more specifically, enabling people to perform visual tasks efficiently and accurately. Proposals are made for lighting metrics that relate to how the quantity and distribution of illumination may influence the appearance of peoples' surroundings, and while the procedure includes work environments, it encompasses all types of indoor activities and locations. The procedure enables lighting design objectives (LiDOs) that relate to peoples' responses to visible effects of lighting upon their surroundings to be specified quantitively, and this leads to the development of a technical specification of lighting installation performance that enables the selection of luminaires to provide the illumination quantity and distribution that will achieve the LiDOs. The implications for both general lighting practice and professional lighting design are discussed.
