LEDs emit neutral light that renders the colors of works of art
as they actually are.
Thus far, museum lighting has faced the thorny issue of ultraviolet and infrared rays from lamps, which can damage works of art. It is also crucial for light to show the actual colors of the works faithfully, and reducing power consumption is also an important issue. For this reason, museums have predominantly used fluorescent or other lighting that emits fewer ultraviolet rays and is thus geared toward museum applications.
A combination of wallwashers on gallery walls and LED spotlights enables adjustment of color temperature tailored to the works on display.
LED light has numerous advantages in a museum. It contains barely any ultraviolet or infrared rays that may harm the artworks, and the fixtures are energy efficient, compact, and long lasting, while high color rendering abilities bring out the original charms of each work. The Panasonic Shiodome Museum, on the fourth floor of the Panasonic Tokyo Shiodome Building, is lit entirely by next-generation light fixtures (high color rendering LED lights) that do a terrific job of presenting each artwork in all its original beauty. LED light is more neutral than its predecessor light sources, and more faithfully renders the actual colors of the works.
LED wallwashers are mounted on gallery walls, and LED spotlights with built-in light modulators on the ceiling. Brightness, color temperature, lighting angle, and other factors can all be adjusted, enabling a wide variety of lighting patterns tailored to the works or exhibition themes.
Also, a networked light modulation system makes it possible to monitor the facilities and adjust light positioning and distribution in response to actual conditions.
A networked light modulation system enables monitoring and adjustment of lighting conditions.
At the Shiodome Museum, replacement of light fixtures with LED has lowered temperatures and reduced the need for air conditioning, and overall power consumption has been cut by approximately 32%. Not only do these next-generation lights do a better job of presenting each artwork in all its original beauty, they are also environmentally friendly.
