DO LED LIGHTS ATTRACT INSECTS?

How many outdoor summer dinners have been completely ruined by that swarm of insects that flutters around the lights? How many times have we had to wait in the dark to be able to close the windows so that the insects wouldn't fly in? Insects, in fact, are endowed with a particular sensitivity to light, which leads them to be attracted or rejected. Some, such as cockroaches, instinctively run away from every ray of light, looking for the first dark corner; others, like moths, mosquitoes or gnats, are attracted to light and fly near it, often even at the cost of their own life, since they risk being killed by the heat of the light bulb. This phenomenon is called phototaxis, that is the correlation between movement and light, and negative phototaxis is defined when its research consists in the refusal of light and phototaxis. This still does not explain the reason for this correlation. Light is, for some insects, a source of orientation: in nature, in fact, they move thanks to the faint light of the moon and stars and fly while maintaining a certain angle with respect to this light. Artificial light appears instead as an inconstant factor invests them on all their sides and prevents them from maintaining an orientation.

But the question that has occupied scholars recently is different: is there a different reaction of insects to different types of light? Studies presented at the AAAS (American Association for the Advancement of Science) conference found the effect of different types of light sources on insects. According to this data, published in the journal Science, these animals are more attracted to incandescent bulbs, while the number of insects that comes close to LED lamps or so-called "bug lights", the lights specially designed to be unwelcome to mosquitoes and gnats.

The LED lights emit neither UV nor heat, elements clearly attributable to sunlight, and are therefore less attractive to insects. If you then choose cold light bulbs, characterized by a brightness more tending to blue than yellow, you can further reduce the number of attracted insects. Obviously, this is not a repellent and does not involve the total absence of these annoying animals, but it is certainly an element of relief for those who want to enjoy the summer evenings outdoors. The LED lights do not, therefore, have the only advantage of providing a precise brightness with greater energy savings, but they are also useful with regard to insects, which are confused in smaller quantities by their brightness.

DIY CHANDELIERS: CREATIVE IDEAS

Image
The chandeliers give a light and a more complete look to any room, but often we don't always find the one that meets our needs and our tastes. Not to mention that many of the most original and design chandeliers have a considerable cost. So how to do it if we want to save money but have a touch of originality and lighting that highlights a room or all of them? With ingenuity we can make a DIY chandelier that perfectly meets our tastes and the style of our furniture! For example, if we have a living room with exposed beams or a tavern to be illuminated we could make a chandelier made of glass vases, such as those of preserves or alternatively in a crystal (scotch bottles). How to do? Just cut the bottom part, insert a bulb holder cable long enough to connect it and then insert the light. The game is done. But a suggestion before making it must be given. You need to choose the type of lighting and the effect you want, so you have to focus on the shapes (drop, round, p...

THE RIGHT LIGHTING FOR A GYM

Image
In a place like a gym, it is necessary to find the right light to create a comfortable environment that helps instructors and all those who attend it. The light, in an environment like the gym, has an importance that could be underestimated. In fact, the task of lighting is not to strain your eyes, so you don't need to have too much artificial light, like white or blue ones, nor should there be direct points that can be too annoying. The right light for a gym must be warm and indirect, and above all uniform. In fact, by creating more illuminated points and shadow points, the eye may become unnecessarily fatigued. If the gym is composed of a single room the ideal is the use of led ceiling lights conical in shape that projects light towards the floor. These must be placed above the tools, at least once every two. Beyond the lights, mirrors must also be chosen which have the function of further illuminating the room and allowing the athlete to check that his movements are corre...
