The eye drives non-visual (NV) responses to light, including circadian resetting, pupillary reflex and alerting effects. Initially thought depend on melanopsin-expressing retinal ganglion cells (ipRGCs), classical photopigments play a modulatory role in some of these responses. As most studies have investigated only limited number NV functions, generally under conditions relatively high light levels long duration exposure, whether functions share similar irradiance sensitivities response...
In past years there has been substantial funding from the European Commission to develop information systems on solar radiation data, such as Solar Radiation Atlas, projects SoDa, Satel-Light, PVGIS, PVSAT, PVSAT-2 or Heliosat-3 and Envisolar project of Space Agency (ESA). Additionally national services were set up Meteonorm by Meteotest in Switzerland SOLEMI DLR Germany. From regional point view, focused mainly Europe its regions, leading situation that several different data bases exist...
The Daylight Illuminant D65, a standardised reference light source in design and research with colour temperature of 6500 K, is often used to describe the daylight. However, it represents an overcast sky, failing capture variability richness actual daylight, particularly blue clear skies. Recent shows that both sunlight skylight significantly influence our mood, perception physiological responses. daylight influenced by factors like sun position, weather conditions, as well geographical...
In recent years, the spectral properties of solar radiation and daylight have become increasingly important in lighting design research, various approaches to implement these been applied. This paper proposes modify adapt CIE reconstruction method, a procedure developed early 1960s define standardised power distributions (SPDs) daylight, for this purpose. The D Illuminants resulting from are widely used standardisation purposes but based on smaller number measurements do not consider...
Many physiological and pathological conditions are associated with a change in the crystalline lens transmittance. Estimates of opacification, however, generally rely on subjective rather than objective measures clinical practice. The goal our study was to develop an improved psychophysical heterochromatic flicker photometry technique combined existing mathematical models evaluate spectral transmittance human ocular media noninvasively. Our results show that it is possible accurately...
The aim of this paper is to present a complete analysis the sky luminance distribution data measured with scanner at International Daylight Measurement Program station in Lyon. Besides presentation distribution, we also derive CIE type based on S 011/2003 standard. gradation and indicatrix functions. Determination group calculation ratio between two elements every almucantar. Since there are six groups, have 36 combinations but only 15 them listed some really rare, provide table show how...
Solar energy is abundant and capable of providing much our needs. It has several uses: photovoltaic, biomass (wood energy, biogas, biofuel), daylighting. For each use, its potential depends on the match between spectral response collector (silicon, retina photoreceptors.) local solar spectrum. Increasing performance technologies by making most spectrum (sun plus sky), requires a better understanding long term variations. Radiative Transfer Models (RTMs) could be used to produce routinely...
This study aims to compare different hyperspectral imaging devices and identify their suitability for in-situ color lighting research. Three cameras were compared radiometric, photometric, colorimetric accuracy. The visual quality of the images obtained with each device was also evaluated test psychophysical experiments on perception. accuracies LED sources correlated temperatures ranging from 2351 K 6922 K. tested found have acceptable radiometric chromatic content photometric accuracies....
