LED street lamps attract, capture dengue-carrying mosquitoes

By eeNews Europe

The LED lamp produces carbon dioxide – by combining ultraviolet light with titanium dioxide – in low-enough amounts that is claimed to be irresistible to mosquitoes. The mosquito trap takes advantage of the mosquito’s sensory abilities by tricking them with features that mimic the odors associated with humans.

Decoyed mosquitoes enter the trap through the capture windows on the upper part, and then are strongly sucked into the capture net in the lower part by a suction fan. Once they are sucked into the capture net, they cannot fly away. The lamp’s self-sustaining green technology allows it to be functional even during floods.

For remote areas with no access to the electrical grid, the system can serve as a stand-alone, self-sustained renewable energy source to supply basic electricity needs. The system is scalable to match the energy demand.

The battery, electrical wiring and controller have been designed to be placed on the top portion of the pole which allows the system to continue functioning during floods. Based on life-cycle analysis – electricity prices are relatively low in Malaysia – the payback period is six years. In urban settings, the installation of the conventional street lights requires landscape disruption in order to have electrical connection.

The invention is capable of reducing the energy demand in urban areas while helping to generate energy in rural areas which may not have access to electricity. More than 96,000 dengue cases had been registered in Malaysia, up more than 19%, according to the World Health Organization (WHO).
