1, I am doing wireless charging, you said the radiation problem should not have any problems, the frequency is very low, if you worry about it can also use the shielding scheme. You don't have to worry about radiation. Enter my nickname to get to my website. You can check out the product.
2, yes, because there is a AC/DC conversion circuit, AC to DC, DC and then inverter to AC as long as there is AC radiation, but the mains frequency is low, the radiation is small, but the conversion is likely to have high-frequency devices, especially in the inverter circuit generally have high frequency,It will produce strong radiation, good electronic products, which have metal mesh cover, is radiation protection. Radiation is everywhere, power lines have radiation, the sun has electromagnetic radiation.
3, not so bad, very little, don't be afraid of treasure mom, it's okay. I wish Xiao Bao health and happiness.
4, from a physical point of view, the chip of the led lamp is very small, so few light chip and driver chip, the radiation of the human body will be very small, the charging power supply is generally lithium pollution is also very little, the radiation is also less. However, the blue light of the led itself is still harmful to the human eye. Current state pairEye protection led lamp, there is no formal specification.
5, with a certain radiation. The lamp has a certain radiation, the specific size of the radiation, need to be judged according to the material of the lamp, the current lamp is mainly the use of energy-saving lamps, energy-saving lamps produced by the radiation is on the lamp. The lamp has electromagnetic radiation like any household appliance in nature, but the electromagnetic radiation decays quickly.
6, mostly the use of LED, it is low power consumption and high brightness, other luminous products can not be compared with it, if it is a rechargeable LED, it is basically no radiation when used, because of itPossible exposure to radiation. Natural radiation passes through the Earth's atmosphere, which means that people are exposed to more radiation in the air when they are at a higher altitude or in an airplane.
Electromagnetic radiation has become one of the pathogenic sources endangering human health. In the electromagnetic field, the incidence of leukemia in the population was 93 times that in the normal environment, and the incidence of muscle tumor was 26 times that in the normal environment. Electromagnetic radiation can induce the proliferation of human cancer cells, affect the human reproductive system, lead to intellectual disability in children, affect the human cardiovascular system, and have adverse effects on people's visual system. Cosmic radiation hazard.
ElectricityMagnetic radiation pollution will affect the replication of lymphocytes, resulting in the reduction of white blood cells and red blood cells, greatly reducing the body's immune function, so that people often suffer from colds, dizziness, head pain, insomnia, neurasthenia and so on. It can also damage the endocrine and metabolic functions of the human body, can lead to cancer, fetal deformity and so on. The higher the intensity of electromagnetic radiation, the higher the incidence of cancer.
Radiation can cause serious damage to the internal chemical environment of the human body by breaking the chemical bonds between various atoms and molecules in human tissues. Destroying human DNA. After being exposed to strong radiation, people will get radiation sickness, radiation sickness will have a period of incubation and then emergeSymptoms are now fatal, abdominal pain, nausea, dizziness, immune system breakdown, and death can occur within days or even hours.
1, electromagnetic wave in the strong range of electromagnetic field is electromagnetic radiation, electromagnetic radiation is electromagnetic wave, electromagnetic wave to human contribution is mobile phones and other radio communication equipment, as well as radar, space telescope, or radio telescope, microwave oven is also using the special relationship between electromagnetic wave and water molecules,Water molecules can amplify electromagnetic wave energy, induction cooker is the use of electromagnetic wave and metal relationship.
2, the progress and application of electromagnetic science and technology for human society to create a huge material civilization, but also brought human into the artificial electromagnetic field. For example, household appliances, office equipment, radio and television transmission towers, urban transportation systems, etc. It can be said that in modern society, electromagnetic fields are everywhere. Scientific research has shown that not all electromagnetic fields will have an impact on the ecological environment, when the energy exceeds a certain limit value will have a negative impact.
3, people often say that electromagnetic radiation pollution is mainlyRefers to artificial electromagnetic radiation, artificial electromagnetic radiation pollution will cause discomfort to the body of the organism, will affect the normal use of electrical equipment, is a special prevention of electromagnetic radiation.
4, the impact of solar magnetic storms on the Earth is significant, it can have a profound impact on the Earth's electromagnetic environment, the atmosphere and human technological systems in many ways. First, solar magnetic storms produce large amounts of electromagnetic radiation and high-energy particles that enter the Earth's magnetic field.
ElectricityThrough the power supply guide rail buried under the ground wireless lamp radiation , the electric energy is transmitted to the electric energy picking mechanism at the receiving end of the vehicle running in a certain range above the ground in the form of high-frequency alternating magnetic field wireless lamp radiation . And then power the vehicle energy storage device. When charging begins, the power transmitter PTx generates an alternating current through its coils, which creates an alternating magnetic field according to Faraday's Law.
The breakthrough of vehicle wireless power transmission technology is to find a way to "catch" electromagnetic wavesThat is, using the "resonance" principle of physics - two objects that vibrate at the same frequency can efficiently transfer energy. The system consists of the main circuit located outside the car and the secondary circuit, rectifier and drive system located inside the car.
The wireless charging principle of the car is by converting electrical energy into electromagnetic waves, which are then sent to the receiver, and then the electromagnetic waves are converted into electrical energy. Charging technology is not complex, mainly the use of electromagnetic induction and magnetic resonance, but the biggest difficulty of wireless charging is that the lack of a unified standard, charging time is too long, efficiency is too low, high cost.
The basics of wireless chargingPrinciple Wireless lamp radiation : electromagnetic induction type: A certain frequency of alternating current in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end.
