LIGHTING

16

ALICE LANE AUDITORIUM B ecause auditoriums and lecture halls are multi- purpose spaces, the lighting within needs to satisfy a range of requirements if it is to accomplish each task successfully. This demands the utmost scrutiny and effort from lighting designers. The Alice Lane Auditorium is remarkable for its faceted ceiling and acoustic panels and Regent Lighting was responsible for matching the lighting to the venue. To do this, the company used a custom designed DALI addressable Linear Mini 24 W p/m. Slender lines of light set in an architectural environment are the essence of the Linear Mini, and its simple elegance and adaptability accommodate the auditorium perfectly. The fittings are

recessed into the ceiling at various lengths and connected continuously at carefully identified angles to meet the design requirements of the intricate modern ceiling. To provide sufficient lighting onto the stage area, Regent used the recessed ceiling mounted Kibo 2001 29.5 W, 4000 K. The Kibo, which is 45° adjustable around the horizontal plane and 355° adjustable on the vertical plane is supplied with an external power supply and is DALI dimmable. The end result is impressive and the auditorium, like the building in which it is housed, is iconic.

LIGHTING A MUSEUM

THE GRAEME NAYLOR MUSEUM in the Timba- vati Private Nature Reserve is devoted entirely to the display of mammals, reptiles and birds found on the reserve. The museum, which has been operational for some time, was recently enlarged and upgraded and Bergstrom Lighting along with Advanced Lighting Systems undertook the light- ing for the new facility. The museum consists of three sections: the main room, which is also used for functions, and two smaller adjacent rooms, one of which houses the butterfly collection while the other is devoted to the display of birds and eggs. The preserved animals and birds (all of which died of natural causes) are housed in units built into the walls, or in free-standing wood and glass display cabinets. A number of the animals are mounted on the walls too. LEDs were used throughout the installation to reduce maintenance and operational costs, provide maximum flexibility, preserve the displays and keep the colour true. Helvar LED strips, with a colour temperature of 4000 K and a CRI of 80, are used in all the cabinets. The fittings, designed and locally manufactured by Bergstrom, tilt 180 degrees in order to minimise shadow onto the animal displays and the fittings in the wooden cabinets are bronze anodised so they do not conflict with their surrounds. Because the site is remote and far from day-to-day supplies, the LED drivers are remote. General illumination from the rafters is achieved using 42 W surface mounted spots with decorative up/downlighters accenting the main room and lighting up the pillars between the built- in displays. Five chrome chandeliers add a graceful element to the venue and enhance its suitability for private functions. Although there was no requirement for control of the lighting, DALI ballasts were installed for future management of the light should that be required at a later stage.
