The working principle of LED formaldehyde purification lamp is that it can stimulate a large number of negative ions, quickly purify smoke and particulate pollutants suspended in the air, and sterilize at the same time, thus purifying the air and preventing pollution. Let the whole space have fresh and healthy natural air. People spend 3/4 of their life indoors. According to expert research, indoor air pollution is many times that of outdoor air. Therefore, it is urgent to purify indoor air, prevent pollution and create indoor ecological environment for people's health! LED formaldehyde purification lamp adopts low temperature plasma technology. When the lamp is lit, the micro negative ion emitter in the middle of the energy-saving lamp instantly releases high-concentration negative ions. Under the illumination of the lamp, negative ions spread evenly to every corner of the space. When negative ions combine with pathogenic cells in the air, the energy transfer structure inside the cells changes, leading to their death. And benzene, toluene, formaldehyde, smoke, dust, pollen, etc. Floating in the air attracts particles to gather and naturally settle, thus achieving the purpose of purifying the air.
