New York's bridges to get multi-million dollar LED facelift

New York City's iconic Hudson River bridges are set to undergo an LED make-over, in a move that mirrors London's 'Illuminated River' project to revolutionise its own river-scape.

Nine New York bridges will receive an LED overhaul during the first phase of the $500 million project, ranging from the Henry Hudson Bridge in the Bronx to the Crossbay Veterans Memorial Bridge in the Rockaways.

Meet the streetlights that are powered by footsteps

Meet the streetlights that are powered by footsteps

A new street lighting system that harnesses energy from pedestrians’ footsteps has been installed in Las Vegas in the United States.

The foot-powered fixtures were developed by EngoPlanet, a New York based start-up. The street lights are part-powered by kinetic energy generated by footsteps, which is absorbed by tiles installed in the pavement. Solar panels are also used to boost energy levels when necessary.

Could LED insect discovery help to beat Zika and malaria?

Could LED insect discovery help to beat Zika and malaria?

A study completed by academics at Bristol University has found that LEDs attract significantly less insects than other light sources. The discovery could be beneficial to nations in South America and Africa, which are fighting mosquito-borne diseases.

The researchers considered a number of different light sources ranging from a tungsten filament lamp to fluorescent light sources and white LEDs and concluded that the heat emitted by light sources has more of an effect on insect attraction than the colour of the light.

Modern building facades can be just as worthy of floodlighting as historic ones. It’s the quality of architecture that counts rather than the age of the structure.

London bridges plan in troubled water as critics pan ideas

The lighting schemes unveiled as part of the Illuminated River design competition to illuminate central London's river bridges have received a frosty response from lighting designers. The submissions, which include proposals to link each bridge with lasers of light, were slammed as ‘impractical’ online. It was also noted by designers that the project will only add further to London’s light pollution problem.

A set of radical lighting schemes have been unveiled as part of the Illuminated River design competition to illuminate central London's river bridges. The submissions, produced by a number of international designers, include proposals to link each bridge with lasers of light, bathe London Bridge in a fiery hue and plant retro light posts in the waters of the river itself.

Is this the world's longest lasting LED installation?

Is this the world's longest lasting LED installation?

Pulsar is claiming a world first after 12 LED panels on the front of their factory building in Cambridge clocked up 11 years of unbroken use. The panels were installed in 2005 and are still going strong now, prompting Pulsar to claim another world record for the longest lasting LED installation.

Smart lighting revolution reaches Swaziland

Smart lighting revolution reaches Swaziland

A network of smart sensory street lights is being installed in the Kingdom of Swaziland. In the West, smart street lights are being used, in most cases, to monitor traffic, but in developing countries they can be put to an entirely different use altogether.

Most Americans have never seen stars due to pollution

Most Americans have never seen stars due to pollution

Nearly a third of people on the planet have never seen the Milky Way, due to artificial illumination in towns and cities. The situation is considerably worse in the United States, where 80 percent of people have never seen an unrestricted night sky view. 

Why LEDs have a key role in the horticulture revolution

Why LEDs have a key role in the horticulture revolution

In the most basic sense, light is crucial for most living things residing above deep sea level. Plants use light to develop by a process of photosynthesis, where CO2 is converted into carbohydrate in the chloroplasts of the plant cells. It is also possible to enable photosynthesis using artificial light, and control the development, shape, and flowering period of a plant.
