The production technology of LED light-emitting tube is developing continuously. The previous light-emitting power was low, the original blue light could not be made, and the red and green were not pure; Now, the process of red, green and blue light has been completed, especially the white light source used as lighting. If it is used as daily lighting, Then its color temperature should be strictly controlled at 2800k (warm tone) ~ 5500k ~ 6500k (positive sunlight), and the photoelectric conversion power should be high, that is, it should not only save power, but also have high brightness and long service life, so it can be really used as a new light source. Now these conditions are basically mature, so they can be introduced to shopping malls. It is said that the South Korean Ministry of housing and urban rural development has included LED lighting in the lighting scheme to be enforced in 2012.

       There is another point about energy-saving lamps that many people do not know, that is, the energy-saving lamps in shopping malls now need to use a large number of toxic gases in the production process, including phosphor and mercury to be sprayed into the lamps! These are very harmful things! And the energy consumption in the manufacturing process is also very large. Some small factories have simple equipment and simple technology, so the quality of lamp products is naturally very poor! (energy saving lamps are basically completed by two or more factories: one for lamp making, one for power supply and assembly; and LEDs are made by large-scale factory automatic production lines with guaranteed quality. Therefore, compared with LEDs, the advantages of LEDs are clear.

        Another problem is that many of the energy-saving lamps sold in our domestic shopping malls are of very poor quality and have a very short service life. Some even break after being lit for one month. In fact, these unscrupulous businesses threw the backlog of things in the warehouse at low prices to the shopping malls to defraud the Ministry of industry and information technology of subsidies for the implementation of energy-saving lamps! This makes energy-saving lamp shopping malls more chaotic! The ordinary people also throw away the broken lamps at will. They don't know that when the lamps are broken, the phosphor and Mercury will be emitted into the air and into the groundwater in the future! This damage to the human living environment is very serious! The consequences are unimaginable!

       To sum up, it is very important to promote a new generation of LED lighting in China.
