According to the roadmap plan to phase out incandescent lamps, from October 1, 2014, China has banned the import and sale of incandescent lamps of 60 watts and above for general lighting. At the "Analysis meeting on the elimination of incandescent lamps above 60 watts" held not long ago, Liu Shengping, chairman of the China Lighting Association, said that due to the rapid development of the lighting industry, there have been many new situations and new problems, which should be given great attention. The promotion of high-efficiency lighting products represented by solid-state lighting sources such as "improved LED lamps" will be the general direction for the development of alternative products for incandescent lamps in the future.

In the past few years, China has mainly replaced incandescent lamps by promoting energy-saving lamps. With the strong support of national policies and funds, the incandescent lamp industry has rapidly transformed, and the energy-saving lamp market has also developed rapidly and achieved remarkable results. "At present, in China's second- and third-tier cities and vast rural areas, although some consumers are still using incandescent lamps, in China's Beishangguang and other major cities, except for the combined crystal chandeliers of some hotels, 60 Watt, 40-watt incandescent lamps have basically disappeared." Liu Shengping said.
"Judging from the current market situation, energy-saving lamps have just become mainstream products in the market, and LED lamps have developed rapidly, which has formed a general trend of LED lamps replacing energy-saving lamps." You Zuowen, general manager of Shili Dengmao (Beijing) Investment Management Co., Ltd. Said that in response to the rapid development of LED lights, the state should adjust relevant industrial policies in a timely manner and give strong support to the LED industry.
Energy-saving lamps usually refer to compact fluorescent lamps, which are coated with fluorescent powder and filled with liquid or solid mercury. The mercury vapor is excited by high frequency and high pressure, and the mercury vapor strikes the phosphor to emit light. Energy-saving lamps can use about 15% of the energy to emit light, and the luminous efficiency has been greatly improved compared to incandescent lamps.
LED is a kind of light emitting diode, which will produce electronic transition phenomenon and cause photon emission when it is energized, and directly emit red, yellow, blue, green, cyan, orange, purple and white light. LED lighting products are lighting fixtures that use LEDs as light sources. LEDs are called fourth-generation lighting sources or green light sources, which are more energy-efficient than energy-saving lamps, but are also much more expensive. With the continuous advancement of technology and the continuous expansion of production scale, the current price of LED lamps has dropped sharply and is close to the price of energy-saving lamps.
"At present, the cost-effectiveness of LED lamps exceeds that of energy-saving lamps, and naturally they have become the main products of merchants." Chen Xuguang, general manager of Beijing Smart Space Rijiujun Company, introduced that in 2013, energy-saving lamps were still the main products of merchants. By 2014, LED lamps It has actually accounted for more than 90% of the products sold by many merchants. The change is really fast.
The LED lights currently sold mainly use the blue light LED technology that won the Nobel Prize in Physics not long ago, that is, by projecting the blue light emitted by the LED chip onto the yellow phosphor inside the LED bulb to mix it to form white light. "Nowadays, the improvement of 'blue LED lights' is also progressing rapidly. By eliminating the driving device, sapphire substrate, etc., there is even an 'integrated light source' that can emit light with only one chip." Office of the National Semiconductor Lighting Industry Leading Group Consultant An Lanpo said that consumers should be made aware of "what lamps we should use".
"From energy-saving lamps to LED lamps or other new light sources, and then to miniaturization and intelligence, lighting products have become more energy-saving, environmentally friendly, and comfortable, and consumers have more choices. This is a good thing." Liu Shengping Said that in the long run, vigorously promoting high-efficiency lighting products represented by solid-state lighting sources such as "improved LED lamps" will be the general direction for the development of incandescent replacement products in the future, and also the general direction for consumers to choose new lighting products.
