Description

Eye protection lamp for repelling mosquitoes by using light waves

Technical Field

The utility model relates to a lamp, in particular to an eye protection lamp using light waves to repel mosquitoes.

Background

Mosquito is offensive because it affects not only work, learning and sleep but also more importantly, the spread of diseases such as malaria, epidemic encephalitis b, filariasis and dengue fever, which are well known to people. How to safely and effectively prevent mosquitoes and expel mosquitoes and take peace in summer is a practical problem which is commonly concerned by people.

With the continuous improvement of requirements on ecological environment, the technical requirements on pest killing are higher and higher, the traditional mosquito repelling products such as mosquito coils and mosquito killing aerosols mainly adopt chemical drugs to achieve the effect of repelling and killing mosquitoes, and the products can cause harm to human bodies after long-term use and can cause the mosquitoes to generate drug resistance after long-term repeated use.

The electric mosquito-repellent incense tablet has good mosquito-repellent effect, but no matter the electric mosquito-repellent incense tablet or the liquid electric mosquito-repellent incense contains organic compounds harmful to human bodies, and adverse reaction can be caused if the electric mosquito-repellent incense tablet or the liquid electric mosquito-repellent incense is used in a closed room. The mosquito repellent liquid is also called mosquito repellent, and its principle is that the medicine can be directly used on the tactile organs and chemical sensors of mosquito so as to repel mosquito. The mosquito killing aerosol is an insecticide, and the main chemical component of the mosquito killing aerosol is a substance called pyrethrosin. The mosquito killing and repelling methods are chemical methods, and chemical substances inevitably contain irritant or toxic substances, so that the method has certain harm to the health of a human body. The conventional physical mosquito repelling method, such as a mosquito trapping lamp, uses phototaxis and sensitivity to a specific wavelength of a mosquito, ultraviolet light is attractive to the mosquito, a lamp tube is used for trapping the mosquito to contact with a net surface, and a high voltage is used for electrically shocking a net wire to instantly burn the mosquito.

Entomologists have found that mosquitoes are sensitive to and prefer certain wavelengths of light and are particularly aversive to other wavelengths of light (e.g., green and yellow). The mosquito repelling lamp can repel mosquitoes by visible light, so that the lamp has no pollution and harm to human bodies and the environment, and is the most safe and environment-friendly mosquito repelling product at present.

The existing mosquito-repellent lamp is mostly manufactured by using phototaxis of the mosquito to light with a certain wavelength as a principle, the mosquito is killed by using a physical or chemical method by attracting the mosquito to a specific device, the mosquito-repellent lamp is strictly a mosquito-repellent lamp and cannot be called as a mosquito-repellent lamp, the mosquito-repellent effect of the common mosquito-repellent lamp is not obvious, various products with uneven quality can appear on the market, and electric energy can be greatly wasted due to unreasonable circuit design of some products.
