Abstract

La presente invención se refiere a un sistema de control de iluminación especialmente adaptado para su empleo en escaparates basado en el mantenimiento del contraste entre interior y exterior sustancialmente constante, ahorrando consumo eléctrico y mejorando la exposición de los productos.#Para ello, el sistema de control de iluminación comprende una fuente de alimentación regulable, conectada con una o más lámparas, un medidor de luminancia configurado para medir la luminancia interior del escaparate y unos medios de procesamiento configurados para estimar la luminancia exterior y el contraste a partir de la luminancia interior medida. Dichos medios son capaces de calcular, a partir de un valor deseado de contraste entre la luminancia exterior y la luminancia interior, la potencia que necesita la fuente de alimentación para conseguir tal efecto.The present invention relates to a lighting control system specially adapted for use in shop windows based on maintaining the constant contrast between interior and exterior substantially constant, saving electricity consumption and improving the exposure of the products. lighting control comprises an adjustable power supply, connected with one or more lamps, a luminance meter configured to measure the interior luminance of the showcase and processing means configured to estimate the external luminance and the contrast from the measured internal luminance . Said means are capable of calculating, from a desired value of contrast between the outer luminance and the inner luminance, the power that the power supply needs to achieve such an effect.
