For the public health, it is essential to determine in what light environment people will develop, live and work in the near future. The present and future of the light environment determine trends in the development of lighting sources. It is important to make a hygienic assessment of the spectra of modern light sources to match the spectrum of the safe sunlight. Trends in the development of led lighting until 2020 and methods of experimental and computer (numerical) modeling of the spectrum of sunlight based on LEDs of various types and their analytical models are considered. The proposed models are shown to allow synthesizing the spectra of led lamps close to sunlight, but they do not meet the requirements of biological adequacy for the human visual analyzer in spectrum width, continuity, uniformity and a set of wavelengths of photon streams that ensure the effective functioning of the human visual analyzer and its hormonal system. The limitations must be taken into account in the development of led lamps by the criterion of root mean square approximation to the spectrum of sunlight and technical implementation to protect the light sensitivity of ganglion cells.
