Because of the LED, we have already passed the stage of energy saving. In the future, we should develop towards smart lighting and people-oriented. This is the future trend of LED. During the Guangzhou International Lighting Exhibition this year, Chen Yansheng, Chairman of China Lighting Association, gave a wonderful speech on the theme and development trend of China's lighting industry at the 2017 Aladdin Forum-Opening Conference. The author has compiled the speeches of Chen Yan's physicist, and shared them with the same people who are lighting people. Overview of the global lighting industry Due to the maturity of LED lighting technology, LED lighting is gradually replacing traditional lighting on a global scale, presenting a long-term situation. Take Japan and the United States as examples: the total amount of light sources in Japan has been declining. Since the 311 earthquake, Japan has promoted LEDs in large numbers. In fact, the share of LED light sources has not changed much in recent years, and the total number of LED lamps is rising rapidly. This is the current status of the Japanese LED lighting industry. In addition, Japan proposes that in 2020, traditional light sources will no longer be produced, and all will be converted to LEDs. By 2030, the traditional light source on the market will be completely replaced by LEDs. In the United States, the total amount of incandescent lamps has fallen sharply in recent years, and the decline rate of fluorescent lamps has also been rapid in the past two years. In addition, halogen lamps account for a considerable proportion of the US market, and LED growth has been very fast in the past year or two. However, in the entire lighting market, the LED replacement situation did not reach the expected speed. During the period, Chen Yan's physicist pointed out that we are one of the important qualities of color rendering when we improve product quality, but Rf can't replace Ra, which is the conclusion reached by international academic circles and industry after years of discussion. This conclusion provides a basis for us to evaluate the color rendering of LED lighting products, and Ra is still effective. In 2016, China's lighting industry slowed down. Looking at the development of China's lighting industry in 2016, the industry's sales reached 560 billion yuan, which was the same as in 2015; exports reached 38.8 billion US dollars, down 14% from 2015. There was a double-digit decline in 2016. This is a change. This change is due to the fact that the curve of LED lighting growth has accelerated from accelerating growth to slowing down, and the overall growth rate has slowed down. Chen Yansheng said. Specifically, in terms of enterprise status, the business conditions of large enterprises are generally good, and the transformation from traditional lighting to LED lighting has been basically completed. Most lighting listed companies have achieved double growth in revenue. However, small business operations have experienced difficulties, and some enterprises have successively transformed or exited the competition in the lighting industry. In terms of product status, most enterprises have switched from LED light source to LED lamp production several years ago. At present, all kinds of indoor and outdoor lamps can use LED as light source, including downlights, flat lamps, ceiling lamps, street lamps for outdoor lighting, tunnels. Lights, garden lights, lawn lights, etc. Among them, the filament lamp has developed rapidly in the past two years, and the cost performance has been continuously improved. The export to Europe and the United States market has been widely welcomed and widely used in the decorative lighting market. In terms of production process, with the gradual maturity of the process, mass-produced products are gradually mechanized and automated. Since LED lighting products have the nature of consumer electronic products, the level of automated production is constantly improving, which also promotes the development of industrial scale. On the basis of LED bulbs and tube production lines a few years ago, the automatic production line of lighting products is maturing. In terms of product exports, the decline in exports of products in 2016 was mainly due to the significant decline in the export volume of traditional lighting products. The export value of LED lighting products was approximately US$12 billion, an increase of 20% over 2015. From the data of various traditional light source exports, there is basically a negative growth, and only the high-pressure sodium lamp has not experienced negative growth. From the data of the export of lamps, the export of fixed lamps, portable lamps, Christmas lights and other lamps also showed negative growth, while LED lighting products (light sources and lamps) showed a slight increase. In 2016, the top ten domestic LED lighting products export enterprises are Lidaxin, Sunshine, Debon, Qiang Ling, Tongshida, Shenghui, Kaiyao, Expressway, Ouke, Philips, among which Lidaxin’s exports reached 426.21 million US dollars. From the perspective of exporting countries and regions, the United States is far ahead, reaching US$446.22 million. The total LED export volume of the United States is basically the same as that of Europe. Except for Japan, exports to Europe and the United States account for the majority of China's total LED exports. In terms of landscape lighting, a major hot spot in the lighting industry in 2016 was landscape lighting, which was affected by anti-corruption and was quiet for several years. It was exploded in 2016. Taking G20 Hangzhou as the representative, a small climax of landscape lighting was set up. This climax continued to this year's Belt and Road Summit and the Xiamen BRICS Conference. In addition, from this year's Guangya Exhibition, you can also see that the exhibitors engaged in landscape lighting are also highly motivated.
