Basic colorimetric characteristics of white light sources have been reviewed. Special attention has been paid to semi-conductor sources. Chromaticity diagrams used presently have been discussed and the approximation-polynomial method of calculating correlated color temperature and Duv has been explained.
Standardized assessment methods of potential hazards connected with the optical radiation emitted by lamps and lamp classification scheme with respect to photobiological hazards have been discussed. The terminology used in the measurements of effective quantities has been discussed and an existing correlation between colorometric function (l) and relative spectral effectiveness function related to blue light hazard B(l) have been explained.
To measure properties like angle-dependant luminous intensity along with colorimetric values like colour, colour temperature and CRI of LED-based luminaries, a goniospectrometer better meets requirements.
The consumer electronics sector has been experiencing a boom in the ever-expanding offering of smartphones or tablets.
