The lumen seen in a new light: Making distinctions between light, lighting and neuroscience

Abstract

The implicit homology between light, lighting and neuroscience limits international commerce, the effectiveness of lighting applications and the relevance of basic and applied research. A comprehensive system where the distinct, but interrelated roles of light, lighting and neuroscience are recognized provides a meaningful foundation for international commerce, for improving the value of lighting for society and the environment, and enriching the neuroscience research agenda. By replacing V(λ) with a broader luminous efficiency function, termed the universal luminous efficiency function [U(λ)], light is better defined. By formally accepting a set of benefit efficiency functions for use in lighting regulations and lighting practice, the value of lighting applications increases. By formally accepting a set of benefit efficiency functions in standards and applications, a platform for collaboration among lighting practitioners and neuroscientists is built.
