LiGO chosen to light the Nation’s art treasures…

October 14, 2011

 Room 63 of the Sainsbury Wing at the National Gallery is the first to have its lighting controlled by LiGO. More by accident than design the artist’s work on show here is famous for their ‘observations of landscape and light effects.’ The LiGO is controlling ERCO OPTEC 14 Watt LED Spotlights with DALI drivers mounted at high level and focused on the 4 walls of the room. These replace the existing 90 watt fittings in the gallery and will reduce the number of lamps from 40 to 25, a significant energy saving .

 Colour rendering properties of the LED means the previously installed combination of blue and clear lamps is no longer required. Control is a combination of natural daylight and artificial light from the roof space above. Where ever possible natural light is used then augmented as required. The control and measurement is through a combination of LiGO and the Building Management System (BMS). Here LiGO comes into its own as it is designed to be interfaced directly to BMS systems without the need for costly interfacing components and engineering.

 Local control in the room is from a LiGO View panel where gallery staff can select scenes from the panel and override the lighting scenes as appropriate. Lamp failures are reported to the BMS so prompt repairs can be made.
