To save the United States in the development of invisible insects "no charm" LED lamp

[LED] according to the British "Daily Mail" reported, scientists from the University of Southern California have developed a less blue and green emission wavelength of LED bulb, moths and other insects less attractive 20%. The era of light attracting swarms of insects is about to become a thing of the past.

The technology could even play a bigger role in the tropics, saving lives, because most of the insects in the tropics carry a large number of potentially fatal diseases.

The light emitted by the traditional light bulb, especially the blue wavelength emitted by the LED bulb, is very attractive to many insects. These insects such as mosquitoes, sand flies, triatomids will increase the risk of human infection of infectious diseases.

At present, a total of 6 million people worldwide infected with Chagas disease, most of them are concentrated in Latin America, and the spread of the disease is the light attracted by the vampire hunters. Pappataci can cause human infection, causing 20 thousand deaths annually; mosquitoes spread malaria, causing 600 thousand deaths per year.

In Australia, a large group of flies into the light

Although we may think that the brightness of the light is attracting insects, scientists from the University of Southern California have shown that the main cause is the color of the light. Travis, associate professor of space science at University of Southern California, said Longcore, the future of LED bulbs can be customized design, reducing the attractiveness of a particular insect. All insects are attracted to white light, but different insects are sensitive to specific combinations of wavelengths.

For example, blue, violet and ultraviolet wavelengths have a strong attraction to moths and other insects, so the LED bulbs are shielded in the experiments.

The team, led by Professor Longcore, with the help of PHILPS labs, hopes to reduce the amount of light that attracts insects, while maintaining the need for white light. PHILPS senior scientist Andr Barroso said: "in order to carry out this study, we design a special one-time LED lighting, by emitting different color wavelength, in order to reduce the attraction of insects. "

The researchers compared this special bulb with existing commercial lighting LED lamps and compact fluorescent lamps. They found that even though the special light bulb was brighter than the conventional LED, it attracted less than 20%.

Professor Longcore said: "the results of this study confirm that we can shield some of the spectrum of the LED lamp, which is detrimental to the environment, while still providing the necessary indoor lighting. It is important to reduce the amount of indoor lighting that attracts insects in places where the world is not yet popular. "(compiled /LED net Flora)
