China plans to completely eliminate incandescent lamps in 2018

Recently, the National Development and Reform Commission is working on the "Roadmap for Incandescent Lamp Elimination", with a preliminary plan to no longer produce incandescent lamps with more than 100 watts after 2015, and to completely phase out incandescent lamps from 2018. Among all lighting fixtures, incandescent lamps have the lowest efficiency. Only 12% to 18% of the electrical energy consumed can be converted into light energy. The rest is lost in the form of heat energy, and the service life is not high, not exceeding 1000 hours.

In 2010, the Australian government launched the world's first plan to ban incandescent lamps to reduce greenhouse gas emissions. In addition, the European Union, the United States and other countries have already proposed a timetable for the elimination of incandescent lamps. In December 2007, China began to implement a financial subsidy system for the promotion of efficient lighting products, and in July 2009, jointly initiated with the United Nations Development Programme and the Global Environment Facility. China is gradually phasing out incandescent lamps and accelerating the promotion of energy-saving lamps. "

According to the statistics of the China Lighting and Electrical Association, there are currently more than 10,000 lighting and electrical manufacturing enterprises nationwide, mainly in Guangdong, Fujian, and Zhejiang. There are too many manufacturers. If they are eliminated at once, they will have many negative effects and need to be phased out.

Relatively speaking, this policy is good for large enterprises in the industry. Large companies have sufficient time and strength to prepare for transformation. In addition, after many countries have proposed a phase-out schedule, foreign incandescent lamp manufacturers have ceased production one after another, which also provides an opportunity for China's incandescent lamp exports.

However, compared to incandescent lamps, energy-saving lamps are not perfect. For example, fluorescent lamps in energy-saving lamps will produce mercury pollution. How to recycle waste lamps is a big problem. Although LED energy-saving lamps are not polluted, they are currently expensive. As the price of LED products decreases in the future, LED lighting will become popular.

LED Bulb

LED is the abbreviation of Light-Emitting Diode. It is made of semiconductor materials. It has a positive pole and a negative pole. When DC is applied to its positive and negative poles, it will emit light. From 1907 to 1993, LED has experienced 86 years of history. The application of LED technology is generally divided into visual and non-visual categories. The application of visual category includes LED lighting technology, and the non-visual category includes plant photosynthesis and medical care.
LED process:
The whole production process of LED Lamp Beads is divided into epitaxial chip production, chip production, and lamp bead packaging. The whole process reflects the manufacturing technology level of modern electronic industry. The manufacturing of LED is a combination of multiple technologies and a product with high technology content. The knowledge of LED for lighting purposes also needs to know how LED lamp beads are produced.
LED epitaxial wafer production process:
LED epitaxial wafer growth technology mainly uses organic metal chemical phase deposition (MOCVD) to produce synthetic materials with semiconductor characteristics, which is the raw material for manufacturing LED chips
