 Lighting control equipment from Helvar is playing an integral part in the new lighting scheme for the Miniature Gallery at the Victoria & Albert Museum, London.
The gallery contains some 150 portrait miniatures on display in 17 cases, and Helvar's DIGIDIM system has enabled the illumination of the miniatures without risking damage to the exhibits.
The gallery tells the story of the portait miniature in Britain, from its first appearancve in the 1520s to its decline with the emergence of photography.
As the miniatures are sensitive to light, infrared sensors are used to operate the lighting only when the exhibits are being viewed. When cases are approached, the lights increase from 10 lux to a maximum of 50 lux, gradually dimming back down after four minutes.
