Lighting Science Group Corporation, a developer and integrator of intelligent LED lighting solutions, and the Office for Visual Interaction, Inc., a global architectural lighting design innovator, announced today that the companies have been selected by The New York City Department of Design and Construction (DDC) to engineer, produce and test the winning design of the City Lights Design Competition. The DDC created this two-stage, international competition to select a new streetlight design for New York City for the 21st century and OVI was selected for its LED-based streetlight design. OVI has partnered with LSG to engineer, produce and test prototypes of its winning design of the LED-based streetlights.
OVI and LSG intend to commence the engineering work this month, followed by testing of the prototypes in Spring 2009 for the City Lights Streetlight project. The goal is to provide a model for widespread lighting of streets, sidewalks and parks within the City's five boroughs.
"Lighting Science is honored to be part of New York City's project to test long-lasting, eco-friendly lights to illuminate our world-renowned streets and boroughs," said Govi Rao, chairman and chief executive officer of LSG. "We are proud to play an integral role in realizing this important carbon-reduction goal. We expect this project will herald a new era of LED adoption and the continued greening of New York City."
"The new streetlight is the first of its kind, and will set the new standard of lighting for city streets worldwide," said Enrique Peiniger, principal, OVI. "The long lasting properties of LED technology enhances security, minimizes maintenance and the energy savings can be considerable as the technology develops. Rather than outdating itself in 20 years, the lighting solution can evolve with technology and improve with age, becoming less costly and consuming less energy over time," said Jean Sundin, principal, OVI.
In this phase of the project, OVI and LSG will be responsible for: -- Fabrication of working prototypes, including all necessary parts; and
-- Performance of all testing necessary to ensure that the prototypes meet all design and performance criteria.
When full development of the winning design is completed and that design is determined to have met the project's standards, New York City intends to add it to the Department of Transportation's Street Lighting Catalogue, continuing its tradition of innovative street lighting that began more than two centuries ago.
There are more than 300,000 streetlights in New York City, the majority of which are based on high-pressure sodium technology. Replacing a commonly used 150 watt high pressure sodium lamp with the proposed LED lighting solution will reduce the energy consumption by 25-30 percent to an estimated 105 watts per LED module.
Winning Design
The winning design developed by OVI combines hi-flux LED technology with state-of-art lensing optics in a small oval-shaped profile, which provides the structural framework and heat sink for the LED modules.
Linear arrays of LEDs are grouped into segments. Each segment has a primary and secondary optics system to achieve the required light distribution pattern. This modular design strategy of components allows usage and interchangeability among the various streetlight configurations. The segmented, modular lighting design innovation for the new streetlight also streamlines fabrication, product handling and can accommodate future generations of LED technology as it becomes available.
