Save people from invisible beauty, research and development of insect "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%. Lights are drawing crowds of insects around, the times are about to become the past.

This technology can even play a greater role in the tropics save lives, as tropical insects carry most of the potentially deadly diseases.

The light emitted by traditional bulbs, especially the blue wavelengths emitted by LED bulbs, has attracted a wide range 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 are infected with Chagas, most of whom are concentrated in Latin America, which is transmitted by lights. 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 lights attracted insects, scientists from the University of Southern California showed that the main reason was the color of the lights. Travis Longcore, an associate professor of space science at the University of Southern California, says the future of LED bulbs can be tailored to reduce the attractiveness of specific insects. All insects are attracted by white light, but different insects are sensitive to specific combinations of wavelengths.

Blue, violet, and ultraviolet wavelengths, for example, have a strong appeal for moths and other insects, so these wavelengths are shielded in the experimental LED bulb.

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 white light needed for the room. 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 the special bulb with existing commercial lighting, LED lights, and compact fluorescent lamps. They found that while special bulbs were brighter than regular LED lights, 20% fewer insects were attracted.

Professor Longcore said: "this study confirms that we can screen some of the spectrum in the LED lamp (those that are not good for the environment) and still provide room for lighting.". It is important to reduce the attraction of indoor lighting to insects in those parts of the world where glass windows are still not widely available." (compiling /LED nets Flora)
