This happened on June 5438+065438+ 10 in 2020. More than 60 such landscape street lamps were installed in Jianghan Road Pedestrian Street in Wuhan, which can be used for lighting and wireless charging. At present, each street lamp has two charging platforms, which can be directly placed in the circle marked with the location for wireless charging, and both of them are high-power wireless fast charging, which Wuhan citizens can turn on for free when shopping, but the current charging platform only comes with it. At present, there are the following security risks, which can be basically ignored. First, the radiation problem of wireless charging. Take the most mainstream qi as an example here. Because wireless charging is the same as wired charging, only the interface is outside, so the circuit should be continuous without charging, so the circuit will cut the magnetic induction line to keep energy, but the wireless charging will emit a low-frequency non-ionizing frequency (1 10-205KHz) that is harmless to human body. First of all, this power is basically harmless to the human body, and the power is too low. Secondly, the charging of street lamps is generally temporary, not long-term, so it can be said that there is no harm to the human body. Finally, the effects of radiation itself on the human body are mostly objective, such as mental state, so the radiation problem can be basically ignored.
Second, the heating of the charging platform causes the mobile phone to heat up. I don't think this is a hidden danger. Because in the usual charging process, if we use the wrong charger model and the charging of the equipment is unreasonable, there will be fever. However, using the original model with wireless charging function has little effect. Here, take Apple's mobile phone as an example. When using iPhone5 wired charging and 3G network to brush Weibo, the mobile phone will generate fever due to running programs and other problems, which is very normal. The heat generated during wireless charging is even less than this. ?
