Save in the invisible America developed on insect "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%. Light attracts crowds around the age of insects will become the past.

This technology can even play a greater role, to save lives in the tropics, because tropical insects are carrying a large number of potentially fatal diseases.

The traditional light bulb emits light, especially blue wavelength emitted from the LED light bulb, are very attractive for a variety of 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 are infected with Chagas disease, most of them are concentrated in Latin America, while the spread of the disease is attracted by the light to triatomids. 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 is the brightness of the light to attract insects, but scientists from the University of Southern California showed that the main reason is the color of the light. University of Southern California associate professor Travis Longcore said the space science, LED lighting can be customized for future design, reduce the attractiveness of certain insects. All the insects will be white to attract, but different insect specific combination of wavelength sensitive.

For example, blue, violet and ultraviolet wavelength has a strong attraction to moths and other insects, so in the experiment of LED lighting, the wavelength was blocked.

A team led by Professor Longcore, the PHILPS lab's help, hope to be able to reduce the number of light to attract insects, while maintaining required indoor lighting. 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 will be the special bulb with existing commercial lighting LED lamp, compact fluorescent lamp experiments. They found that, although the special bulb lamp is brighter than the conventional LED, but to attract insects less 20%.

Professor Longcore said: "the results of this study show that, we can be part of the spectrum in LED lamp (which is bad for the environment part) are shielded, and still provide indoor lighting required. In the world that have not yet universal glass window, reduce indoor lighting is very important to attract insects." (compiled /LED Flora)
