Light affects many aspects of human physiology, through the non-image-forming (NIF)
pathway. To account for this pathway, lighting design simulation tools need to combine …

This study developed a low-cost, portable and wireless spectrometer to measure Spectral
Power Distributions (SPD) of light sources with a resolution of 3.5 nm in the visible spectrum …

There is a high relevancy in the luminance distribution related to the perceived visual
comfort. Moreover, the required technology is maturing such that it is feasible to integrate …

Light is an essential element of building design that influences human health, comfort,
performance, and well-being. Humans' daily rhythms in behavior and physiology, such as …

A large portion of the Dutch working population spends a significant amount of time in the
office environment. Therefore, it is essential that high quality lighting is achieved. However …
