each exhibit was favoured. How did you obtain this result, knowing that at the time of the general project design you did not know which works of art would be chosen? By considering project requirements that included very small works of art as well as large works of art on the wall. Actually this need was used as a rigorous selecting instrument in identifying products available in the market that could respond with a high quality to the double task of illuminating very small to very large exhibits. Undoubtedly, here the great ability of the manufacturer / supplier who had to optimize the relation of the efficient light-flux of the LEDs and the very high quality level lighting designed for the delicate task of adapting to the most diverse situations, was seen. A narrow spot is a unit with a very narrow beam of light, with a less than 10 ° beam angle, however a wall-washer is a type of unit that carries out practically the opposite function. The former is designed to concentrate all the available light energy within a target spot, that is circumscribed and " clean ". The latter must distribute light over a vast background, challenging the limits of optical-physics and the law of light, in which the intensity is inversely proportional to the square of the distance. In other words it must compensate for the effects of the distance and angle, so that the value of the work of art is enhanced without the interference of any light smudging, visible geometric concentrations or however non-homogeneous light visible to the naked eye. A very delicate task!
Do you also think that a good project is the representation of an excellent compromise between the requirements of the museum and those of the architecture, tied to the context of space? Can this be made easier today by solid state light sources? How? Certainly! In these years the content and versatility of the instruments that are available to the lighting designer are changing greatly and the choice of the LED universe is now quite common for projects that require a high technical quality and duration in time, bearing in mind the advantages in terms of preservation of the works of art, and energy efficiency. Besides these qualities, I might say that miniaturization has an important role in integration in the architecture. Furthermore, minimalism and a certain amount of rationalism are ingredients that mix well with spatial structures that are rich in history, and decorative and monumental archetypes, however this type of design must be chosen along with the innovations that the museum needs today. It is clear that in this passage towards a qualitatively flexible light with a great potential, as is offered by LEDs, something really new is being defined: the possibility of managing not only static but also dynamic situations. In other words, everything that can be seen today by the eye and the mind, when a planned variation in the lighting allows us to make use of a new way of describing a work of art, a collection or a prestigious site. In this sense, the fact that we speak of electronic light is absolutely crucial, because it represents the potential of the digital age, that can stimulate our senses towards the discovery and re-discovery of the vast and extraordinarily rich culture of Italy.

ANDREA NAVA " In Italy we have very talented lighting professionals "
You became a supplier of the new lighting system in 2015 / 2016. What type of work did you expect? Palazzo Diamanti is a name that evokes important historical references, and when architect Pasetti told us about this great exposition, there was great curiosity. There were going to be works of art on loan from the most important international museums, and the quality and controls of the lights were crucial elements in order to view such masterpieces. After many years, I must admit that it is particularly in delicate situations like this, that Erco performs best, and the installations that we completed with very qualified Italian lighting designers are a proof of this. I like to point out that they were Italian, because in Italy we have lighting professionals who can compare with famous names from other countries. And Pasetti is certainly one of them.
Since some time the public visiting museums and exhibitions is increasingly demanding with regard to visual perception. This is also the inauguration of a lighting design project which is estimated to last many decades. Is there anything you believe can improve as a result of this experience, in a future exhibition or exposition site? Art curator Barbara Guidi has succeeded in an exceptional feat with this exhibition that is really unique, which describes Ariosto from an unprecedented point of view. The work carried out by Pasetti astonished me due to his ability to balance the light of the entire course of the exposition. For someone working in the field of lighting engineering, to admire masterpieces that are so delicate from the point of view of their preservation, illuminated with 30-40 lux and not missing even the smallest detail, is a reason to be proud. It is an excellent example of high quality-illumination, where the control of light, using high precision optics and management of light intensity, becomes a key element for a perfect view of the exhibited works. Knowing that Palazzo Diamanti has decided to invest in a state of the art lighting system, characterized by great flexibility and duration in time, is a rewarding approach that the public administrations are choosing to apply more and more often for works of the Italian cultural heritage.
