WASHINGTON: An Indian-origin designer has developed unique 'smart' street-lamps which light up only in presence of people, an invention that could slash energy costs by 80 per cent.

The 'on-demand' streetlights only glow in the presence of a people, bicycle or car, and remain dim the rest of the time

The system dubbed Tvilight was invented by designer Chintan Shah while a student at Delft University of Technology in the Netherlands.

Shah, while flying overseas, noticed street-lamps lighting streets that, in the middle of the night, were empty and desolate, CNN reported.

"I started researching. I wondered, why are they burning? How much does it cost? Is this a problem? I discovered some amazing numbers," he said.

Shah said that Europe pays over USD 13 billion a year powering streetlights, which accounts for more than 40 per cent of government energy bills.

His offered a solution to develop an intelligent, lighting system using wireless sensors to conserve energy.

Shaw believes the system will slash energy costs and CO2 emissions by 80 per cent, and maintenance by another 50 per cent, due to the integrated wireless sensor that allows lamps to alert a central control center.

The technology to distinguish between people and smaller animals, like cats and mice, so it would avoid lighting up unnecessarily has also been developed.

"I thought, why should each citizen pay for street lights that aren't being used? We now have a solution for that," he said.

Tvilight has already been implemented in four municipalities in Holland and one in Ireland.

"We have enquiries from Israel, Turkey, the United States, Australia, India and Japan. The problem is not a lack of enquiries, it's the team's capacity to deliver the solution worldwide," he said

research on this sort of pedestrian aware smart street lights based on wireless sensors has been around for many years. it might be useful in deserted areas, but it requires extremely high public safety level, and in the states, such areas are usually quite dangerous for people to walk around even fully lit.

Sorry. But is this new?

In my part of America, infront of our garage or behind in backyard, we have those "on-demand" lights all over the place.

Just a link from the Lowe's:

Shop Utilitech 360-Degree 3-Head LED Motion-Activated Flood Light at Lowes.com

Description:
360-Degree 3-Head LED Motion-Activated Flood Light

•3-Light, 360-degree motion detector area flood light
•No-tools adjustment for desired coverage
•Total 1929 lumens output
•14 x 3W LED's with power supply (Cree XP-G model)
•Energy star rated

Or LED Sensor Ceiling Light which is much better: http://www.goldenkayi.com/upfile/20130307110557575.pdf‎
Function:
1、In the low intensity environment , human body moves in induction area, the ceiling lamps light and delay about 1 minute to close.
2、In the higher brightness environment, human body moves in induction area,the lamps do not light.
3、Inductive zone 8 M farthest,Induction Angle is 140 degree.
4、Different light mode:
Mode 1:When Induction to human body,ceiling lamp 100% bright,fully closed after a delay.
Mode 2: When Induction to human body,ceiling lamp 100% bright,after a delay the brightness is 30%.
This mode is applicable to the place can not all the dark,such as footpath,stairwells,ect.
5、Can install the built-in sensor or the external one according the needs.

Exactly the concept is very old .
May be the writer doesnt really know what sort of smart behaviour does the light have.Not just turing the light on off. there may be other features to it. Other wise it nothing but a rip off . :D

In 1990s, we have already applied this lamp in apartment buildings. A slight sound or move could trigger the light on, nothing new.

You mean its kinda like a motion detector?

Next Indians will invent lights that turn on and off by clapping.
