Chai Jing's smog investigation triggered a nationwide anti-smog campaign under the dome, and for the lighting industry, which accounts for a large proportion of total electricity consumption, effectively reducing energy consumption has become the trend. According to Ma, the main source of smog is pollution from combustion, mainly from chemical, petrochemical and steel industries. Lighting has little effect on emissions, but fly legs are meat! "If we could all use better, more energy-efficient light sources! And with the corresponding control system, the lights will automatically go out when not in use, and reduce more unnecessary lighting, such as building appearance lighting, urban landscape lighting, etc., which waste electricity and have no practical significance, I believe our air will be cleaner!" "Mr Ma stressed.

It is well known that before the introduction of LED lighting products, fluorescent lamps were widely used as energy-saving lighting sources. The luminous principle of fluorescent lamps determines that the lamps must contain a small amount of mercury vapor, which has certain pollution to the environment. In the interview, Ma repeatedly stressed that the mercury in the fluorescent light source is extremely terrible for groundwater and soil pollution, and it is almost impossible to compensate in our lifetime. "Fluorescent lamps have been in the market for decades, but sadly until now have been almost phased out without a recycling system in place. In my opinion, the market entering the LED era will completely eliminate fluorescent light sources, and it is urgent to establish a recycling system."
