In 2018 the transition from incandescent sources to LED luminaires, in July 2021 the second intervention to digitalize and improve the efficiency of the lighting system: thus the National Gallery of Umbria has chosen to focus on adaptive management and the valorisation of existing technologies. Project objectives, edited by Turin-based company Rimaniincrease energy savings and reduce maintenance costs.
Results obtained thanks to a more rational use of light, connected to the real use of spaces, without requiring the replacement of fixtures. A reuse-oriented philosophy that aims to improve the use of products, avoid waste and promote adaptive lighting management in the museum rooms. The system today manages to adjust the light intensity independently depending on people’s movements, with operational and economic benefits.
Details of the lighting upgrade
To create this controlled lighting, the 42 rooms of the National Gallery of Umbria were made independent of each other. Inside each room, then, a presence detector that activates the lights as visitors pass by. The entry of people into a room involves turning the lights on in the two rooms that follow, to avoid sudden lighting. Simple and intuitive management of LED luminaires, enabled by Casambi bluetooth system.
The plus of this choice? Power create and modify scenarios in every room and on every illuminated work. Not less important, intervene on the electrical system without making any changes and in accordance with the constraints of the Superintendency of Fine Arts. In fact, even by replacing the existing tracks with DALI solutions, it would have been impossible to create the passage of data BUS inside a 1500s historic building on five levels, 10,000 m2 of illuminated surface and stone walls 80/100cm thick with few openings.
Technologies and advantages for the National Gallery of Umbria
Let’s start from the lighting choices with the Solar projector, installed in 2018 and updated in its variants Solar 100, Solar 100 compact, Solar 60, Solar 60 wall. In addition, Stay selected i Longitudinal and PRO4 products. The first is a linear LED fixture with high color rendering, with a 20mm diameter, designed for quality diffused light on frescoes, paintings and walls. PRO4, on the other hand, is a system for the installation of electrified tracks for projectors, linear luminaires, hooks for suspending pictures/panels and the passage of electrical cables. In short, the ideal solution for a historic and listed building like that of the National Gallery of Umbria.
The use of projectors with magnetic secondary optics has also made it possible to direct and illuminate only the works on display, avoiding unnecessary waste. All with warm light, around 3000K, and illumination values contained in the 100/150lx range in order to preserve the works as much as possible.
As for the benefits of the intervention, the solution integrated by Rimani effectively responded to the client’s technical requirements. In particular, regarding the operating costs of lighting systems, thanks to a simpler and more intuitive management for museum managers. The updating of the systems contributes to protection of works of artas well as the improvement ofvisitor experience.
