Implementación de una nueva concepción científico-educativa en el diseño de exhibiciones en el museo de historia natural de Pinar del Río, sustentada en sistemas de iluminación LED

The followed approaches are presented for the assembly of an exhibition of cavern ecosystems with some outstanding archaeological elements, for that which the basement of the current installation of the Museum was selected. For the planning the illumination expositive system, was selected the LED (Ligth Emition Diode) technology. The types of lamps were selected before the placement of the exponents. The assembly of the cavern was carried out using the technique of papier maché where different physical and biological elements of this ecosystem type were inserted. It is pointed out how derived of this technological application, an energy saving was obtained of more than 60% compared with the assemblies that use the fluorescent lights. It was made and it validated a didactic proposal so much for this exhibition type that facilitates to establish a more interactive holistic speech, from the physical point of view as cognitive. It is emphasized in that the implementation of the LED technology has allowed the recovery of three Rooms of the Museum like permanent rooms of exhibitions, at the same time that it allows an assembly of high efficiency and durability.
