In a concise, but accessible for the first acquaintance form the procedure for the quantization of linear oscillator is set out. By analogy with this procedure the procedure of quantization (second quantization) of classical Maxwell’s electrodynamics is set up. The physical sense of the wave functions arguments of transverse electromagnetic field and its Fourier transformation is set up. One pay attention as for quantum coherent (almost a classic) states of the electromagnetic field and for photonics Fock states. Attention is drawn to the fact of absence the power of the universal content of such concepts as field amplitude, phase and number of particles (photons), which are used by experimenter’s to describe the states of a quantized field. The semi quantitative description the interaction processes of a quantum electromagnetic field with substance is set up. Specified situations are shown in which the discrepancy between the predictions of classical and quantum electrodynamics is noticeable at the macroscopic level.

Research indicates that intrinsically photosensitive Retinal Ganglion Cells are not evenly distributed or evenly sensitive throughout the retina. Still, most research looking into non-image forming (NIF) effects uses an integral measured quantity, illuminance or melanopic weighted irradiance, to represent the amount of light at the participantsХ eye level. This paper describes a theoretical approach to define the effective radiant flux for stimulating the ipRGCs, taking into account a spatially resolved sensitivity. Research on retinal sensitivity is scares and not yet substantial, but the methodology can easily be adopted when areas of specific sensitivity are set. Preliminary results indicate that, with similar vertical illuminances and spectral power distribution, typical office lighting solutions might have a lower NIF effectiveness than settings with higher luminances in the central part of the field of view. This could explain why research on NIF effects is inconclusive, even though reported lighting conditions are similar.

The standard tool for characterizing road surface photometry is the reduced luminance coefficient table (or R­table), as defined in the seventies by the CIE. Since these tables are no longer representative, measuring road photometry is necessary for optimizing a lighting installation and ensuring luminance level and uniformity. The objective of the study was to characterise and follow on site the photometric characteristics of different concretes with time and traffic. A first experiment was done with two concrete formulations (broomed and water jet scrubbed concrete) located around a much circulated concrete mixer plant. The photometric characterisation of these pavements was done with the portable reflectometer COLUROUTE device during three years. The selected surface treatment was applied in a tunnel and the photometric characteristics were measured during 30 months. It was shown that the concrete pavements are more diffuse and clear than classical pavements. Their use could generate significant energy saving.

Road lighting is on the verge of one of the most attentive changes since its first introduction. The synergetic effect of the advancement of road lighting technology and usage pattern is going to change the concept of road lighting. By most estimates, light emitting diodes (LEDs) are the most energy efficient light sources that can be used in road lighting. Today, the energy saving potential when replacing HPS lamps with LED luminaires is one-third with current technology and two-thirds with improved technology in the future. This technological transformation has the potential of energy saving up to 83 % in comparison with HPS lamps. The energy saving is achievable with changing the pattern of use by intelligent road lighting control based on reducing burning hours. Intelligent road lighting can be based on such parameters as traffic density, ambient light, road condition and weather circumstances. It can also be more dynamic and consider the combined effect of road lighting and individual car headlights. The widespread adaptation of these emerging technologies is envisioned to lead towards more sustainable lighting.

As an emerging industry, photovoltaic industry has won strong support from the government. However, many problems appear in industrial development with increasing maturation of photovoltaic industrial development. The governmental effect has a critical bearing on photovoltaic industrial development as governmental policies-driven industry. In order to investigate the influence of governmental intervention on growth of photovoltaic enterprises, sample data related to photovoltaic enterprises in Chinese A≠share market during 2007Ц2017 were selected, and the influences of fiscal subsidies and tax preferences on growth of photovoltaic enterprises were analyzed. The results show that both fiscal subsidies and tax preferences have positive promoting effects on growth of photovoltaic enterprises and influence of fiscal subsidies is more obvious. The conclusions provide decision-making support for the government to formulate intervening policies facilitating growth of photovoltaic enterprises.

With flourishing development of media industry, media have exerted more and more important functions in the capital market. For photovoltaic industry, which is an emerging industry, its innovative behaviours need support from the capital market. In order to investigate the influence of media reports on innovative behaviours of photovoltaic enterprises, 43 listed photovoltaic enterprises in China A­stock market were selected. 2013–2016 news reports related to photovoltaic enterprises were grabbed using Python method, and the influence mechanism of media reports on innovative behaviours of photovoltaic enterprise was explored. The results show that media reports facilitate innovative behaviours of photovoltaic enterprises. Facilitating effect of media reports on innovative behaviours of photovoltaic enterprises further strengthen with increasing business revenues of the enterprises. Policy-oriented media exert obvious effect on boosting innovative behaviours of photovoltaic enterprises, while market-oriented media have no significant influence. The conclusions contribute to further understanding of the effect exerted by media information dissemination on enterprises’ innovative behaviours.

Further understanding the building occupantsТ needs and behaviors can reduce lighting energy consumption. This research explores how the occupancy and interior architectural aspects become effective in manual lighting control in offices. It involves a multiple sectioned questionnaire focusing on the possible architectural factors such as the desk position, the surface colors, the distance to window, the distance between desk and lighting switch, and inquiring participantsТ manual lighting control behavior through the photographs of modified interior layouts, surface colors and time intervals. Statistical methods are used to determine the significant aspects, which may reduce the use of lighting control. Interior layout, distance to window, time of the day, and number of occupants in the offices are the most significant contributions to the manual lighting control behavior. To pay attention in these contributions, it would be possible to reduce the use of electricity for lighting while user satisfaction increases.
