Two Stages

A new concept of the architecture of hybrid lighting systems for installations of combined lighting is considered. The cascade principle of constructing the optical path of such complexes is described, in which the design contains two stages of the cascade: the upper and lower stages. The upper (input) structure is made on the basis of the corresponding modification of the hollow tube “Solatube®” (daylight), and the lower one, based on the “Solatube®” fibre of a larger diameter, is combined with LED artificial light block and is designed to transmit mixed light (daylight and artificial light). The results of studies on the efficiency of light transmission made it possible to optimize the solution of the new modification of the hybrid lighting complex “Solar LED”, lower stage of the cascade, and to develop the nomenclature of the production line “S”. The description of the first experience of using this complex in the pilot combined illumination system of the “meeting room” in the shopping centre “IKEA Belaya Dacha” headquarters is given. A completely autonomous power supply system for a lighting installation based on solar panels has been implemented.

Enveloped in artificial light, many urban dwellers have never experienced real darkness. Seeing this as a loss, scholars and organizations have initiated discussions on light and darkness and advocated the preservation of the dark skies. This article aims to further this study by emphasizing the importance of the stars. Instead of studying lights, stars, and darkness ethnographically, the article examines the ideas of stars and darkness in Thierry Cohen’s photographs and two of Vincent van Gogh’s paintings. This article will suggest that the dark, star-filled skies represented in van Gogh’s paintings provide a visual blueprint of what the article calls the “star-lit cities,” which goes beyond a simple preservation of darkness, and may be significant in driving vital changes in combating the current environmental crises.

Diversity Of Life

Elements of the physical aspects of urban environments determine which micro-organisms, plants, and animals live in urban environments. In this chapter, climate, air, water, soil, noise, and light are discussed. Urban environments are affected by the climate of the region in which they are located, and in turn and create their own, distinctive urban climate. Air, water, and soil are all affected by urbanization. Pollution of these elements is common. High noise levels and artificial light at night (ALAN—a new phenomenon) are both strongly associated with urban environments. Details of both are discussed. The discussion in this chapter provides a foundation for further exploration of the diversity of life in urban environments and for later exploration of how organisms adapt to urban living, which will be discussed in Parts II and III.
