The most heavily polluted countries are China and India. As far as China is concerned, Beijing, Tianjin, Hebei and most areas have shown severe air pollution, which seriously affects people's health and production activities. It restricts the sustainable development of the environment and social economy. The management of fog and haze is now truly of global concern. Currently, the primary means of managing fog and haze levels is the traditional method of absorbing them via an artificial spray. It takes a considerable workforce and material and is neither economically nor environmentally friendly. This can easily contribute to secondary pollution. Street lamps it is an essential but necessary element of urban infrastructure construction. It has a wide range of distribution. If environmental energy power can be used, the high-energy electron plasma technology on street lamps might be an effective way to solve problems. The practicability and application value of streetlights will be significantly improved. However, most existing street lamps still use an external power supply, which consumes enormous energy and quickly leads to traffic jams when the line fails. There are more potential security risks. At the same time, the existing roadside devices do not availably solve the problem of haze pollution. My invention, "Streetlight Eco", effectively solved the above issues.
