Recently, the Global Efficient Lighting Forum hosted by the United Nations Environment Program was held in Beijing. Jan Denneman, president of the Global Lighting Association, predicted at the forum that the transition from incandescent lamps to LED lighting heralded a revolution in lighting energy efficiency. The United Nations Environment Program has analyzed the lighting market in more than 150 countries around the world. At present, lighting power accounts for more than 15% of global electricity consumption, and carbon dioxide emissions account for 5% of the world; and the application of advanced lighting technology represented by LED can Reducing carbon dioxide emissions from more than half of the world's lighting use is equivalent to the entire Australian emissions. With this lighting energy efficiency revolution, it is green and smart lighting. Recycling and utilization can not be ignored. According to Robert Koppejan, director of the International Environmental Consultation Center, how to recycle and utilize used lighting products is the final step in completing the closed loop of efficient lighting. According to Robert's experience, it is the first step to establish consumer awareness of the recycling and utilization of lighting products. The next step is to collect and recycle the waste products into glass, plastic, mercury, etc., and obtain reusable raw materials. Robert pointed out that the establishment of an effective recycling mechanism requires professional institutions and a large amount of financial support. Moreover, there are still many problems in terms of the recycling and utilization systems established in developed countries. For example, although the Swedish lighting product recycling system is worth learning, it is based on the high environmental awareness of consumers, and it is difficult for other countries to replicate its model. Many countries still lack a unified recycling system. The most typical is the United Kingdom, whose lighting product recycling system actually As many as forty, for consumers, if you want to distinguish between different types of products for recycling, recycling will be very complicated and not operational. Robert stressed that LED lights also need to be recycled. In 10 years, LED lights will be popularized, and some pollutants will still be produced. However, due to its small size, consumers often do not have a sense of recycling and utilization. Therefore, it is necessary to conduct consumer education from the beginning, strengthen the construction of a financing system for recycling and utilization, and create a unified, simple and easy-to-use waste lighting recycling system. . Robert concluded. Wisdom lighting can't be seen at the forum. China Semiconductor Lighting Technology Evaluation Alliance signed a cooperation agreement with the international Wi-Fi Alliance. This is in the view of Chen Yansheng, secretary general of the China Lighting Association, which is an inevitable measure to develop lighting technology and interconnection technology to a certain extent. The combination of lighting technology and mobile internet is also one of the important trends in the development of smart lighting. The application of smart lighting in the field of road traffic has attracted the attention and optimism of the industry. It is also one of the initiatives that have achieved remarkable results in building smart cities in recent years. For example, the LED luminaire adopting the wireless intelligent control system can adjust the brightness of the night tunnel illumination to ensure the optimal illumination brightness in the tunnel, and effectively avoids the waste of electric energy caused by excessive illumination of the traditional fluorescent luminaire during the night operation of the tunnel. The advent of the era of big data has made intelligent lighting more and more interesting. Chen Yansheng pointed out that true intelligent lighting should not be restricted by mobile phone apps, manual operations, etc., but on the basis of collecting big data, fully realize intelligent lighting. Wisdom lighting is advancing, but the real market has not yet been formed. The reason is the development of technology and the limitation of economic level. There is still a long way to go to the popular wisdom lighting. Chen Yansheng said.
