Researchers at the University of Malaya are using streetlights to combat the spread of dengue fever in Malaysia.
The outdoor energy efficient LED lamp essentially gives off a ‘human scent’ that attracts mosquitos and traps them.
Might sound simple, but there’s a lot going on under (and above) the surface. The LED lamps produce UV light that shines on a titanium dioxide surface, causing the release of small amounts of CO2 – mosquitoes are attracted to humans and other prey by following CO2 trails. Then, once the insects are close enough, they get sucked in by a fan and trapped in a net.
Powered by wind and solar energy, these street lamps are effectively off the grid, so can go in even the remotest parts of the country, providing light while controlling disease.
