Daylight uniformity
WebNatural illumination (daylight or skylight—analo- gous to total and diffuse radiation) is normally meas- ured with a photometer resembling a pyranometer. Ideally, the spectral response of the sensor should be the same as that of the human eye. In practice, this is best approximated through the use of a sele- nium barrier-layer photo cell ... WebThe more uniform daylight is distributed in the required illuminance range, the more light stability is achieved, and the longer time is illuminated by daylight, the more electrical lighting...
