New York's use of Induction Lighting
Citizens, users and customers everywhere are demanding that lighting be more efficient and lower maintenance.
"It's not just a theme of 'saves energy' anymore. We're concerned about quality of life, reducing maintenance and improving lighting environment," says Peter Jacobson, lighting specialist with New York City-based utility Consolidated Edison Inc., who is working with Osram Sylvania and the New York Parks and Recreation Department to install high-tech induction lighting in New York City parks.
Union Square Park, Battery Park and parts of Central Park have been converted, Jacobson says.
The market is slowly accepting the technology, and these new lighting systems will eventually become the standard, he says.
"Once we install this light source, we don't have to go back for 15 years. That light source we displaced, you'd be changing that every two or three years,"
Jacobson says.
Still, there is no guarantee anytime soon that
the incandescent bulb will be switched off permanently, says Sandra
Vasconez, manager of program development for the Lighting Resource Center, a
research center at Rensselaer Polytechnic Institute in Troy, N.Y.
The electrodeless lighting that New York City is installing in its parks has
been available for 10 years, but is not widely used, she says. It is now
only used for very specific applications, even though it is lower cost in the long run, she says.
"Nobody is paying attention. Why? Because their first cost is very expensive,"
she says.
LEDs, which depend on electronic systems, will also become more commonly used, especially as white LEDs are perfected, she says. And the market is watching their development closely, she says.
"I know its going to be a big light source, but I don't know that it's going to replace incandescent lamps. Incandescent lamps are most convenient, energy aside. I can go to the store, to my supermarket, to buy one for 25 cents,"
she says.
Even though LEDs will save energy, the design must still be further advanced, and manufacturers must adopt the technology. When that happens, some issues will disappear quickly and make LEDs more competitive with incandescent lighting, she says.
Other design trends are also influencing the market. Architects and interior designers are seeking smaller sources of light to illuminate space without intruding, says Christina Trauthwein, editor in chief of New York City-based Architectural Lighting magazine.
The market for old-fashioned incandescent bulbs remains strong, however, Vasconez points out.
In the United States, they are considered more convenient, and in developing
countries, they are all that people will be able to afford, she says. And
for that reason, none of the big lighting manufacturers will shut the lights
off on their incandescent bulb business, though it may not be where they
look to make their money.
