In this annual industry event, many domestic and foreign companies in the semiconductor lighting industry chain participated in various fields such as professional lighting, decorative lighting, LED technology, professional lighting, light source, lighting control system, lighting production equipment and instruments. The products are on display. Through these product displays, how many people feel the changes or trends in the industry, sort out the feelings of the scene for a few days, and communicate with you. Pragmatic and rational mentality is valued. Throughout the development of semiconductor lighting, experienced the initial silence and high-profile, in the eyes of many people in the industry, semiconductor lighting is fading away and returning to rationality. At the exhibition site, in the exchanges with many industry insiders, the reporter deeply realized this pragmatic attitude, paying attention to quality, focusing on doing their own good things, has become the direction of many enterprises. Talking about the current development status of the industry, products and technologies, Dr. Liu Guoxu, Executive Vice President of Yimeixinguang, told reporters that in the past few years, everyone will introduce various concepts, such as COB, CSP, etc., with the popularity of technology and on the product side. Application, after the concept, requires more pragmatic and application innovation. The industry needs rational development, and must not blindly follow the trend. Everyone has to do what they are good at. Shi Songgang, deputy general manager of Huacan Optoelectronics, said that Huacan Optoelectronics's series of actions this year are very interesting. For the development of Huacan Optoelectronics, Shi Songgang said that Huacan Optoelectronics needs to understand the needs of customers and provide complete solutions. Provide customers with the best products. During the exhibition, Huacan Optoelectronics exhibited its high-voltage LED chips, filament LED chips and other products and solutions and promoted its flip-chip series. When the corporate mentality is more pragmatic and rational, semiconductor lighting technology is also continuously improving. From the exhibition site, relatively mature and developing technologies such as flip chip, high voltage chip, COB and CSP package are still on display. However, compared with the frequent concept of previous years, the craze is frequent, and the frequency of new concepts has indeed decreased in recent years. Intelligent lighting is at the time. Intelligent lighting and smart home are hot words in the current industry. They are still in the process of exploration and development. There are distances from large-scale applications, including user demand, technology improvement, and standards. However, this does not hinder its attention, and it is still a major attraction in this exhibition. For smart lighting, the sense of experience is a factor that companies value very much and want to convey to the audience compared to the form of a specific product display. For example, Sanxiong Aurora and Feile Audio use the smart home experience pavilion to display and promote their products in a way that makes people feel the experience. In addition, the construction of smart cities is in full swing. In this boom, smart street lights seem to be a breakthrough in smart cities, and many companies inside and outside the industry are involved. At this exhibition, some companies, such as Zhilian ICT, exhibited their smart street lighting system products. UV LEDs are attractive. Ultraviolet LEDs are widely used in security, disinfection, curing and other fields. The market prospects attract enterprises' attention. The current proportion of UV LEDs in various enterprises is not high, but it has been included in many places to see and see. This year, many companies still exhibit UV LED products, including Hongli Optoelectronics, LG Innotek, Yiguang, Tiandian Optoelectronics and other enterprises. Plant lighting is waiting to take off. Plant lighting for agricultural lighting applications has been the focus of the industry. This year, some companies have also exhibited related products, such as Citizen, Pinyi Lighting and other enterprises. Almost all areas of modern agriculture are closely related to artificial light, and artificial light in agriculture will be ubiquitous. Compared with high energy consumption, low light efficiency; poor controllability, difficult to control light quality and light intensity; traditional artificial light source with large difference in spectrum and plant photosynthesis demand. LED monochromatic light can be combined, energy-saving, cold light source, good controllability, long life and obvious advantages, providing opportunities for modern agricultural applications. According to statistics, the global LED plant growth lamp is expected to be around US$300 million in 2017. According to the scale of China's LED agricultural market, the facility horticultural area is 60 million mu, of which about 45 million mu needs to be supplemental light source; plant (miao) factory More than 1 million square meters. The ideal scale of the LED agricultural market is estimated to be over 4,000-450 billion yuan. The application prospect of LED in the field of agricultural lighting is unquestionable. Plant illumination is a relatively mature part of agricultural lighting applications. Although there are many applications, there are still many problems in terms of price, demand satisfaction, and technology improvement. After the summary: equipment, chip, packaging, heat dissipation, drive, intelligent control, phosphor and other technical levels continue to improve, light efficiency, color rendering index, light quality and other indicators continue to improve; Internet technology, smart city, smart home, etc. The development has brought unlimited imagination to the LED lighting industry. The development of intelligent lighting can be expected; the field of general lighting is fierce, and the sub-areas such as plant lighting, automotive lighting and UV LED are gaining more and more attention. In addition, since the beginning of this year, the most frequent occurrence is the transformation, mergers and acquisitions, integration, a series of events, people are dizzying, such as the road to the sale of Philips lighting, the final choice of independent listing; Osram notice will be officially split in July The company's general lighting subsidiary Ledvance; German semiconductor equipment manufacturer Aixtron (Aixtron) intends to sell, the acquisition may be Chinese capital can be foreseen, the industry pattern will continue to change, and intertwined in environmental, technology, application and other factors Next, there will be a new world in the LED lighting industry, we will wait and see.
