Evaluations of long-term lighting qualities for computer labs in Singapore

چکیده
This paper presents a study that investigates lighting qualities within three computer labs from long-term perspective. Subjective assessments 173 participants were collected. Accurately calibrated simulation models of generated to simulate annual quantities based on horizontal illuminance (Eh), vertical (Ev) and monitor (Em). Gender, eyewear access exterior views have impacts subjective assessments. Due the low daylighting distributions, climate-based daylight metrics (CBDM) with thresholds over 300 lx, including autonomy (DA) lx 500 Useful Daylight Illuminances (UDI) autonomous (UDI300–3000 lx), UDI-exceeded (UID>3000 lx) Annual Sunlight Exposure (ASE) 1000 (ASE1000 are inapplicable in context this study. UDI-fell-short (UDI <100 UDI-supplementary (UDI100–300 associated Ev outperform other CBDMs terms predicting satisfaction daylight. In addition Eh- Ev-based predictors, Em-based ones practically correlated However, contradictory correlations logistic regression between predictors found across daylit lab electrically lit labs, which emphasizes importance differentiating according type, sources classroom arrangement.

متن کاملLighting Controls for Computer Cinematography
Lighting is an essential component of visually rich cinematographic images. However, the common computer graphics light source models, such as a coneshaped spotlight, are not versatile enough for cinematographic-quality lighting. In this paper we describe the controls and features of a light source model for lighting computer graphics films. The model is based on generalized light cones, emphas...
