Mona Lisa Projector

A Led lamp has been exclusively designed with the purpose of giving the highest lighting quality to Mona Lisa painting. This new design has been financed by the (well-known) Japanese firm Toshiba. The new lamp has been installed in a shelf designed by the room’s architect (Lorenzo Piqueras, 2005) . This system works upwards and is composed of 34 LEDs (single chip and multi chips. It replaces the former 7 LED lamp that had been working since 2005. Three optical systems have been developed in order to obtain high illuminance uniformity on the painting: primary optics on the LEDs, a “Scheib” mixing the colours, and a third system consisting of a double lens with an integrated filter, focusing the light on the painting and regulating its quality. A framer was also incorporated. The other aim of this lamp is to control freely the colour temperatures, keeping a high CRI (>95) with a maximum Gamut Area (in relation to the scientific research of the International Lighting Commission).
