Which lighting strategy can conserve works of art?
Light for high conservation requirements
High quality LEDs with a low-damage, museum-compliant spectrum and controlled illuminance levels fulfil the conservation requirements of museum lighting.
Directing the focus onto the art with a dark background
Presenting works of art to a wide public and simultaneously protecting light-sensitive exhibits poses major challenges for designers. LED technology and an appropriate lighting strategy ensure visitors have an impressive experience of art despite high conservation demands. High-quality LEDs enable lighting without damaging spectral components in the UV and IR ranges.
Conserving exhibits with dimmed light
To protect light-sensitive exhibits, the illuminance of spotlights can be individually set via potentiometer dimmers to limit this to an acceptable level. In contrast to halogen lamps, the colour temperature of the LEDs remains constant. This means that even with strongly dimmed LEDs an authentic impression of colours and materials is maintained.
Emphasising pictures with crisp-edged projection
To offset light-sensitive pictures using high contrast in dark surroundings, crisp-edged light beams can be used instead of soft gradients. This effect is created with contour spotlights. The projected area is precisely matched to the format of the artwork using a slider. The intensive contrast between bright and dark at the edge of the light projection gives the impression that the painting illuminates from within, despite the low lighting level.
