One of Australia’s most iconic stretches of road in the nation’s capital, Anzac Parade went through a complete facelift in time for ANZAC Day 2017. The upgrade provided the Parade with impressive, even illumination befitting the importance of this national monument.
Stretching from the Australian War Memorial to Capital Hill and the Australian Federal Parliament House, Anzac Parade commemorates the members of the Australian and Imperial Armed Forces who served in the major wars.
The Anzac Parade lighting upgrade involved the replacement of the existing 150W induction fittings in all 116 poles with LED modules from Gerard Lighting.
A key challenge for Gerard Lighting was that the LED upgrade could not significantly change the appearance of the luminaire design, which was inspired by the distinctive helmets worn by ANZAC forces during World War I.
The brief sought illumination to V2 category lighting standard (AS/NZS 1158.1.1), which required the light output to be increased by 30% while power consumption had to be reduced by 40%. The fitting also needed to be capable of being dimmed to V4 category lighting after midnight.
To ensure balance between driver safety, comfort and visual aesthetic to accompany the gardens, displays and monuments along the Parade, each luminaire had to provide total maintained output greater than 5,300 lumens, with a maximum intensity of 3700 cd required at 45° vertical and 67.5° horizontal. Optics needed to meet the IES specification for Type II full cut off performance. Additionally, the luminaires had to avoid leaking any upward light from the main optics to control light pollution into surrounding streets and residences. All light technical parameters had to be equivalent to or better than the original 150W lamps.
Weighing in at 95kg, each light fitting was large and difficult to manoeuvre. The fittings were also sealed to ensure they retained their IP65 rating for at least 15 years, reducing the maintenance requirement.
Gerard’s solution involved 6 STLED modules and a custom dimpled reflector system with the appearance of a large luminous opening to reduce the glare impact. A large internal heatsink was designed to dissipate the 80W of power while a dimmable driver allowed power to be adjusted to suit the V2 to V4 category levels.
Key advantages delivered by Gerard’s LED modules over the original induction lamps included a longer rated life of >88,000 versus 60,000 hours; higher lumen maintenance over life (0.8 versus 0.7); reduced power consumption of <85W versus 165W; and dimmable function saving even more power. Each pole is fitted with a 2-channel C-BUS controller, allowing the LEDs to be programmed to dim after peak operating hours.
ANZAC Parade’s LED upgrade project was a true team effort involving close collaboration between Gerard’s sales, engineering and manufacturing personnel and partners in Ecowise and ACT local government.
