Urban Space and Electric Light

AbstractSince its invention, electric lighting has had a decisive impact on the psychogeography ofurban space. Concentrating on the period from 1880 to World War II, the author argues thatelectrical lighting has been a major factor in the emergence of modern urban environments, inwhich the traditional function of architecture as a stable ground has increasingly given way toa growing mutability of forms and fluidity of appearances. This tendency both paralleled andconverged with the effects of modern media technologies such as cinema, contributing to theemergence of a new environment characterized by relational space, in which the city isincreasingly defined by the overlap of material and immaterial spatial regimes.Keywords: electricity; light; modern city; perceptual experience; relational space.One of the main issues in contemporary urban spaces and ways to improve its quality, Andthe entrances of cities as the first entrance to the city where the audience is confronted withits spatial quality is very important, Input cities have in the design of cities. In this paper, weinvestigate with a view to improving the quality of urban spaces and to provide input in orderto upgrade the quality of the environment and the city s entrance. Descriptive analyticalmethodology and data collection of books and articles have beennumerous mysteries, features inputspace Sakhtarkalbdy cities, always manifested elements of environmental, social, cultural,respectively. Input the cities as joint connecting natural space and artificial atmosphere insidethe city as well as to establish the relationship between the city and the surroundings of somespatial relationship patterns follow. Spontaneous and uncontrolled expansion and unplanneddevelopment of towns and not according to proper spatial development patterns weaken inthe form and content of the input spaces of cities in Iran. Since the input space in cities is oneof the urban spaces. And, even can be the first space in dealing with the phenomenon ofthought, According to the spatial relationship of input and current patterns of thisphenomenon is one of the most fundamental studies of the approach in urban areas. So as toachieve appropriate solutions in the design and organization of the current input of the cities,Due to the nature of the input and understanding of this phenomenon and also features one ofthe most basic issues Input should be considered Keywords: entrance to the city, improving the quality, components of the environment,urban environment.
