Light a bulb yet keep the flies away.

Light a bulb yet keep the flies away.

Everyone enjoys spending the long summer evenings beyond the walls of home. Be it enjoying a cold lemon tea in your garden or playing along with your siblings, everyone loves to spend the summer evenings joyfully. But one thing that bugs this sweet evening is the insects outside. Many solutions to get rid of these bugs are available in the market. Ranging from mosquito repellent cream to anti-insect sprays. Unfortunately, all of these come with some or the other side effects. Some mosquito repellent creams might cause allergy or skin irritation. 

Asthmatic patients might be sensitive to anti-insect sprays or worse. So what is the elegant solution for this bug? Definitely, staying inside the house is one but let’s not bereft our young generation from enjoying the summer evenings..

In order to have fewer insects attracted by the lights, researchers have devised a new combination of series of colours to attract minimal number of insects. This light bulb is very simple yet an elegant solution to avoid attracting insects by the lights. While fluorescent and existing light bulbs emit light consisting of all the wavelengths from the visible spectrum, the energy-efficient light bulbs are more inclined towards the blue wavelength of the spectrum.

 Too much exposure to a particular wavelength, say blue light may cause disruption in the circadian rhythm of human beings, not only this but at the same time these wavelengths attract the insects and bug our lives. In order to avoid attracting the bugs , researchers have combined a series of LEDs which emit light of different wavelengths from the energy spectrum. This was to minimise the emission of blue and green light which is suspected to be most attractive for the insects. The resulting combination of light is claimed to attract 20% lesser insects than the conventional light source. Moreover, the combination continues to lighten up the surrounding with white light, thereby causing no discomfort to us.

The prototypes are already being tested and are giving positive results. Researchers say that there is more scope of expanding this technology. They believe that there are other combinations of LEDs possible which may give even better results than the current configuration. Maybe further research may yield a complete bug-free environment, till then we can be a little cautious about the insects around. Don't let them bite you.
