Abstract

This study presents a practical, evidence‑based strategy for lighting design in night‑work environments. It brings together insights from prior research on both visual effects (how we see) and non‑visual effects (how light affects the body beyond vision). A case study with spatial and lighting analyses grounds the strategy in real‑world conditions. The outcome is a schematic design diagram with three lighting schemes tailored to spaces with low, medium, and high levels of functioning. Each scheme sets out principles for four key elements: corneal illuminance (light at the eye), surface illuminance (light on surfaces), correlated color temperature and spectral power distribution (CCT/SPD; the color and spectrum of the light), and distribution (how light is spread in the space).

Dette studie præsenterer en praktisk, evidensbaseret strategi til belysningsdesign i natarbejds­miljøer. Strategien samler viden fra tidligere forskning om både visuelle effekter (hvordan vi ser) og ikke‑visuelle effekter (hvordan lys påvirker kroppen ud over synet). Som grundlag anvendes et casestudie med rumlige og lysmæssige analyser for at sikre, at anbefalingerne kan bruges i virkelige rum. Resultatet er en skematisk designoversigt med tre belysningsskemaer målrettet rum med lav, mellem og høj funktion. Hvert skema beskriver principper for fire centrale elementer: korneal belysningsstyrke (lys ved øjet), belysningsstyrke på overflader, korreleret farvetemperatur og spektral effektfordeling (CCT/SPD; lysets farve og spektrum) samt fordeling (hvordan lyset spredes i rummet).
