We propose the analysis of the control systems associated with ornamental lighting applied to the architectural and monumental heritage from our teaching experience developed since 2017 at the University of Córdoba-Illumination Faculty of Philosophy of Córdoba, year 2017, and Center of Experimental Culture in the Plaza de la Corredera, year 2018-and the lighting project of the facade of the Hospital de Santiago de Úbeda, Jaén. The DMX system is the one which mostly fulfill the requirements of this kind of lighting. Its implementation is increasingly simple and is associated in many cases with the type of luminaire to be used and the particularity of differential wiring. This solution allows a personalized, creative, and dynamic control and the adaptation of the daily lighting to different events of singular character. It can be used as an instrument of economic revitalization of the tourist and commercial sectors, and of diffusion of the architectural and historical heritage values. The application of the Internet of Things (IoT) and Big Data could allow the creation of a predictive model that helps the spectral design of light sources and an objective tool that contributes to the confluence of art and science.
