New Osaka Street Lamps Lit by LUXEON® Power LEDs
Philips Lumileds today announced the installation of the first street lights
using LUXEON power LEDs in Osaka Prefecture in Japan, reflecting
the emergence of solid-state lighting as an energy-efficient alternative to
street lamps using standard light sources. The fixtures, developed by Osaka-based
Three Force, are contributing to an overall savings of 88% in electricity
bills over the older high-pressure
mercury lamps used elsewhere in the region.
"Our new street lamps in Osaka are saving a tremendous amount of energy and pedestrians really enjoy the quality of light that we get from the LUXEON LEDs," said Mr. Kazuaki Ueshima, CEO & President, from Three Force.
Each of the LED-based street lamps installed at a park on the Kizu River utilizes 36 cool white LUXEON LEDs. The LED array generates 30 lux at a pole height of 4.5 meters, comparable to the brightness of mercury lamps, while using just 25 W of power per fixture.
In addition to energy savings, LUXEON LEDs offer a 60,000-hour lifetime that is 5 to 10 times longer than mercury vapor, mercury-free construction, and the ability to achieve uniform light distribution with minimal glare in street lamp applications because of the greater control over light direction made possible by LUXEON’s small form factor. Light can be precisely targeted through LED placement and optics optimization.
“This initial installation in Osaka Prefecture is part of an emerging movement to bring LED illumination to streets and sidewalks. We are seeing growing interest in solidstate street lamps from partners and cities around the globe and certainly here in Japan” said Norihide Yamada, General Manager, Japan for Philips Lumileds. “Municipalities are familiar with the energy and maintenance benefits of LEDs, and street lighting promises to be the next big wave of LED adoption at the municipal level.”
