Lysande belysning? En komparativ sutdie mellan belysningsmöjligheter och rekommendationer

Abstract

One part of preventive conservation is controlling the lighting in the exhibitions. As a first step we have to accept the fact that the very act of displaying objects is causing them damage, and because the trend is for everything to be open to the public view all the time, the aim is to minimize light exposure of exhibits. This essay will present lighting options and relate them to the current recommendations. I have put the emphasis upon describing which methods one can use to minimize the degradation of exhibits on display by eliminating UV- and IR-radiation and reducing the visible light. The intention with this essay is to investigate the current lighting options and compare these to the recommendations on lighting exhibitions. The selections of different lighting options such as LED-, halogen- and energysaving lamps were made based on avaibility. Thereafter I did two types of investigations. The first one was to examine how much luminance, UV- and IR- radiation the lamps gave on 1, 2 and 4 meters and the second one was to determine at which distance you received the recommendations 50 and 200 lux. The results were put in relation to the recommendations and analyzed. The results I had from the investigations are that there are two different types of lamps that are suitable for lighting in museums. These are the LEDsavers 48 and OSRAM halogen spot R63 ES. The LED lamp is a little bit better because it does not emit any UV- or IR- radiation.
