It is well known that solar energy is an energy source that can be regenerated and has no pollution. Therefore, the application of solar insecticidal lamps developed in agriculture and other industries is naturally an eco-friendly and energy-saving agricultural technology product. It gives us the entire agriculture, Economic, social, and other industries bring more benefits and are of great significance to human progress and development. From the 1958 fluorescent lamp in our country to the black light in 1964, the prevention of farmland pests and the development of today's solar insecticidal lamps took a while.

Nowadays under the background of the country’s strong support for renewable energy and the rapid development of solar energy, new types of solar insect killer lamps have been widely used. Solar insecticidal lamps use solar photovoltaic modules to convert solar energy into electricity during the day and store them in maintenance-free storage batteries. At night, the control system automatically turns on the high-voltage power grid and LED light sources according to the light illumination. The ultraviolet radiation emitted by the LED lamp generates a phototaxis effect on the insects, which induces the insects to pounce on the LED light source. The LED light source is configured with a high-pressure killing net to kill the pests when the pests plunge into the light source, thereby achieving the purpose of killing pests.

At present, most of the wavelengths of the light emitted by the LED lamps used in the solar-powered insecticidal lamps on the market are the wavelengths of ultraviolet light of a special wavelength of 365±50 nm for pest trapping. In Ding Yanqin’s behavioral selection experiment of 13 monochromatic lights on Helicoverpa armigera, it was found that the peak of the visual acuity curve of Helicoverpa armigera was at 333 nm; whereas the solar insecticidal lamp found in the phototaxis experiment conducted by P. We have a phototaxis response to monochromatic light above 333 nm. From the above findings, we can find that the various phototaxis pests have different visual acuity curves.

Because the energy used by the solar insect killer lamp is quite unique, its advantage is that many power-supply insecticidal lamps cannot reach it, reduce the number of insecticides used, reduce the cost, and make pesticide residues in crops and vegetables in people's lives. Less, this is an important way to protect food safety. At the same time, reducing environmental pollution is undoubted. Maintaining ecological environment and balance is an important significance brought about by solar insect killer lamps.

Bearing rings: Dimension tolerance, geometric tolerances, and surface quality of bearing` s working surface will influent the operating noise. Naimei Bearing adopts precision CNC machining to dimension precision, geometric tolerances, design drawing, mold making, grinding, cleaning, assembly, testing, every link of strict checks, so as to ensure all our products are tested by our strict criteria.

Balls: The balls evenly with by the cage, often make rolling movement between 2 rings. The shape, size and number will directly influent bearing`s load tolerance and operating capability. We use high precision, small vibration steel ball. It`s surface must be strengthened, no bumps scratches, lacerations, pitting and notch.

Cage: Enclose and move with all or part of the balls. It also be used to insulate the balls, guide the balls` movement and to improve lubrication performance inside the bearing., etc. Naimei Bearing`s cage is commonly made of cold rolling carbon steel. But in the corrosiveness environment, nonparallel or high-speed situation, stainless steel, engineering plastics cagecan be decided on request.

Seal: Naimei Bearing adopts different kind of seal material to meet the requirement of their operating in high temperature and being compatible with grease. Acrylonitrile-butadiene rubber is our standard material. but in high temperature environment ,often adopt fluorocarbons, silicone , PTFE shield.
