Scientists at the University of Malaya have used solar panels and mosquitoes to be attracted to light and human odors to create energy-saving LED streetlights . Not only can it fight the local severe dengue epidemic, but it also successfully combines public health with renewable energy.
In order to combat local dengue fever disease, scientist Chong Wen Tong has developed a led street lamp with a mosquito trap, powered by solar energy and wind power.
According to Chong, the mosquito-trapping device uses the characteristics of mosquitoes to favor human odors, and the mosquitoes are easily attracted by ultraviolet rays. The system also integrates weak ultraviolet rays and suction fans.
Ultraviolet light reacts with the titanium dioxide generated by the reaction between the trap and the photocatalyst, and then produces carbon dioxide exhaled by humans. When the mosquito is successfully trapped, it will be inhaled by the fan to reach the bottom of the net, so it cannot escape.
In addition, in order to avoid the shading effect and maximize the collection energy, the solar panel is designed above the system, and the vertical axis wind turbine (VAWT) is composed of an Omni-Directional Guide Vane (ODGV) that can increase the wind speed. Covered, and the circuit is designed above the light, suitable for use in areas prone to waterlogging.
The Guardian pointed out that there are currently 8 street lights set up on campus and in downtown Kuala Lumpur. The research team has completed a licensing agreement with a company, and the first version of the street light is ready for commercialization.
According to the World Health Organization (WHO), the dengue fever outbreak in Malaysia rose to 19% in 2015, with 96,000 notified cases, and the number of dengue deaths in the same year also increased. From January to November 2014, 162 people have increased to 282. .

The RJ-45 interface can be used to connect the RJ-45 connector. It is suitable for the network constructed by twisted pair. This port is the most common port, which is generally provided by Ethernet hub. The number of hubs we usually talk about is the number of RJ-45 ports. The RJ-45 port of the hub can be directly connected to terminal devices such as computers and network printers, and can also be connected with other hub equipment and routers such as switches and hubs.
