Are the ultraviolet rays from mosquito killer lamps harmful?

In summer, we often see mosquito-killing lamps in gardens, and mosquitoes are always killed, but are the ultraviolet rays from mosquito-killing lamps harmful? In fact, everyone thinks that mosquitoes are killed by ultraviolet rays, but it is not. It is just a purple light that attracts mosquitoes and then kills them with electric current. Of course, excessive ultraviolet rays are harmful to the body, so we must do a good job of protecting against ultraviolet rays in the summer, but mosquito killer lamps do not use this principle.

It is not ultraviolet and is harmless to the human body. Mosquito lamps can be divided into two types: electronic mosquito killer lamps and airflow mosquito suction lamps. The mosquito killer lamp has the characteristics of simple structure, low price, beautiful appearance, small size and low power consumption. Since no chemical mosquito-killing substances are needed during use, it is a relatively environmentally friendly mosquito-killing method.

The working principle of the electronic mosquito killer lamp is to use the mosquito's phototaxis to attract mosquitoes and electrocute them to death. It uses high-efficiency mosquito-attracting lamp tubes, which have a high efficiency in attracting mosquitoes and other harmful flying insects, and can kill flying insects instantly through static electricity shock. The electronic mosquito killer lamp circuit is designed with current limiting, low power consumption, and high efficiency. It can be used as long as the power is turned on, and no chemical substances are volatilized. The airflow mosquito-absorbing lamp with a fan absorbs mosquitoes through airflow, thus killing them. The airflow mosquito-absorbing lamp is small in size and can be carried around, and is generally used in households. There are various models of electronic mosquito repellent lamps, and the larger ones are generally used in hotels and restaurants.

Generally speaking, a 12W electronic mosquito killer lamp can control an area of ​​12 square meters, and a 12W airflow mosquito lamp can control an area of ​​25 square meters, but the mosquito killing range of both is limited to one room. Airflow mosquito-absorbing lamps cannot be hung, but electronic mosquito-killing lamps can be hung. If they are placed in places where mosquitoes often appear, the effect will be better.

Expert advice: Although mosquito-killing lamps are environmentally friendly, they are relatively passive in repelling mosquitoes, a bit like sitting back and waiting for something to happen. It should be noted that mosquito repellent lamps are somewhat dangerous, especially in families with children. They should be placed high up to prevent children from touching them. In addition, do not insert conductive objects into the high-voltage grid to avoid electric shock. The mosquito killer lamp should be placed at a height of 1.5 meters to 2 meters to achieve the best killing effect. The "popping" sound made when electrocuting mosquitoes and flies is a normal phenomenon.

In addition, the dust on the fluorescent tube should be cleaned regularly and the power grid should be cleaned with a small brush. When cleaning mosquito and fly residues, the power supply must be cut off and the power grid must be short-circuited with a screwdriver to discharge any remaining power. The outer cover of the airflow mosquito killer lamp can be removed for cleaning, but the power supply inside must not be splashed with water. Finally, it should be noted that strong light should be avoided from directly shining on the electronic mosquito killer lamp.
