LED-based fixtures, designed with help from Future Lighting Solutions, are being installed at Chidorigafuchi Park for the annual cherry blossom festival. ![]()
Solid-state floodlights recently installed in Tokyo's Chidorigafuchi Park were developed specifically to reduce the park's carbon footprint, particularly during the annual cherry blossom viewing season when the park plays host to thousands of people every night.
The new luminaires, which utilized Luxeon LEDs from Philips Lumileds, were designed by Nagasaki-based lighting manufacturer INEX Corp. Engineering support was provided by Future Lighting Solutions, the exclusive Luxeon supplier and LED application development specialist.
The transition from halogen to solid-state lighting is saving an estimated 90% in energy consumption and carbon dioxide emissions for each replaced fixture, helping the park do its part to combat global climate change as well as advancing Tokyo's efforts to become a model low- Carbon city.
In addition, the cooler LED beam and lower UV levels will provide a more flower-friendly environment that will help keep the cherry blossoms in peak bloom for as long as possible during the annual festival.
The INEX Sky Highbeam-X floodlights developed for the park come in 7- and 14-LED models with light outputs of up to 2800 lumens. The fixtures are built with Luxeon K2 LEDs, containing TFFC (thin-film flip-chip) devices. These were selected because of their ability to be driven at 1000mA to meet high brightness requirements.
Future Lighting Solutions' contributions to the project included thermal management support, as well as helping INEX meet an aggressive product development timeline by eliminating the need for extensive prototyping. Future's proprietary QLED thermal simulation software enabled rapid modeling of heat distribution as well as luminous flux without Lengthy trial-and-error design cycles.
Future also solved INEX concerns about LED color uniformity within each shipment as well as from order to order by guaranteeing a supply of LEDs from several cool-white color bins that met the project's specific requirements. Future's binning program offers 19 color bins for cool-white Luxeon LEDs alone.
