Digital light as a concept of media theory

Abstract

This article introduces the concept of “digital light” into the Russian-language space of media theory, and also offers its conceptualization as a distributed network medium that transforms cultural practices. The article substantiates the need to distinguish digital light as a separate concept. Unlike the concept of “electric light” introduced by McLuhan, the content of the concept of “digital light” is based on the constructive and physical features of this medium, and not on abstract ideas about “pure information”. This article describes the media properties of digital light, determined by its semiconductor structure and the property of sampling the electrical signal. It substantiates the productivity of considering these structures in the context of a broad concept of digital light, rather than individual technological forms or software solutions. Considered not as a separate technological form, like a light bulb or a screen, but as covering the entire set of radiating and controlling means, and as a dynamic developing network, the elements of which can be both visible to a person and invisible to him (as a part of the infrastructure), digital light creates various situations of multi-channel exchange of electrical signals, eliminating the boundaries between its own digital structure and the illuminated objects of the environment. In particular, digital light allows interactive digital installations to exist and can process and visualize big data in real time. Digital light, understood in this way, turns out to be a medium with its own “message”, which overcomes McLuhan’s claim of electric light as a “medium without a message”.
