At the time of the Internet and the concept of the Internet of Things, German academics and industry representatives first proposed the Industry 4.0 research project. After the Hannover Industrial Fair in 2013, the concept of Industry 4.0 spread rapidly from Germany to Europe and began to influence the world. The German federal government attaches great importance to Industry 4.0. In its High-Tech Strategy 2020, Industry 4.0 is identified as one of the top ten future projects and has risen to the national strategy. The government has invested 200 million euros. This concept is of great significance for advancing the fourth industrial revolution. From this we can easily introduce the era of industry 1.0, 2.0, 3.0: Industry 1.0, the first industrial revolution, which took place in the UK in the 1860s. This industrial revolution is widely used as a steam engine as a power engine. It completely changed the way of production of products and created an era of replacing manual labor with machines. In the first half of the 19th century, the machine itself was produced using machines, marking the completion of the industrial revolution. After the United Kingdom, France, the United States and other countries have also carried out the first industrial revolution. Industry 2.0, the second industrial revolution began at the turn of the 20th century. This industrial revolution was based on the division of labor, using large-scale production of electric drive products, thus bringing humans into the electrical era of mass production. Industry 3.0, which began in the early 1970s, introduced electronics and information technology to automate the manufacturing process. The machine not only took over a significant percentage of manual labor, but also took over some mental work. Through the summary of the industrial development stage, I can't help but think of the LED lighting industry. Since the development of red LED lighting tubes by GE Monsanto and IBM Joint Laboratory in 1962, the application range of LEDs has become wider and wider, and the application speed has become faster and faster, from indicators, displays, outdoor lighting, automotive lighting to ordinary Lighting, LED has penetrated into every aspect of our lives, and also directly led to the revolution in the lighting industry. As part of the electronics industry, the LED lighting industry also follows certain development rules. In order to better understand the past, present and future of LED lighting, It is necessary to divide the different stages of LED lighting development. This paper attempts to do some definitions of LED lighting development in different time periods and product characteristics. The purpose is to inspire and improve, and welcome to explore. Although LED was invented in 1962, its time for real lighting began in 2000 when OSRAM, Germany, invested $500 million in white LED industrialization projects. Since then, PHILIPS has integrated the upstream and downstream industries of LED through the power of capital. Japan NICHIA, CREE and other companies have also increased the industrialization research of lighting-grade white LEDs, while rapidly improving the performance of white LEDs, The cost of LED is reduced, which greatly promotes the technical progress and application speed of LED. Therefore, I feel that 2000 is the appropriate starting year for LED lighting. Secondly, the main LED lighting products are still in the stage of replacing traditional light sources and lamps. It is expected that in 2015, the lighting efficiency of mainstream lighting products will reach 100lm/w. Functional replacement can be achieved for traditional lighting products. According to the current technology development trend, it is expected that by 2020, the whole lamp will be eager to reach 200lm/w. At the same time, according to the characteristics of LED, the application and products of LED lighting will be innovated and unified to realize the LED lighting in the true sense. Based on this, we try to imagine different stages of development of LED lighting: Lighting 1.0 era: 2000-2015 (E), the overall lighting effect tends to 100lm / w, for traditional light sources and lamps can achieve the replacement of lighting functions, application forms It is the main way to imitate the shape and photoelectric parameters of traditional light sources and lamps. Lighting 2.0 era: 2016 (E)-2020 (E), the overall lighting efficiency tends to 200lm / w, LED bulbs, LED spotlights, LED tubes and other light source products are gradually reduced, based on LED characteristics of lighting integrated lighting The product category has gradually become the mainstream, and dimming and intelligent control have begun to spread. Lighting applications have also evolved from the current lighting needs to the demand. Lighting 3.0 era: 2021 (E) the overall lighting effect tends to 300lm / w direction, LED lighting and construction gradually merged into a part of the building. The luminaire has active signal transmission and feedback reception, passive signal reception and recognition functions. The intelligent control transitions from one-way communication to the illumination system (including the control system) and realizes two-way interactive communication with the object, and integrates functions other than illumination. As a lighting person, our future is bright! Although the current industry competition has become incandescent, enterprise development is in an impetuous period: everything wants to be done, changes are too fast, corporate resources can't keep up, listed listings, financing financing, and others are making big money, only It is difficult to make up his mind if he is not able to earn money himself and is in a contradiction or entanglement. In fact, we are now in the LED lighting 1.0 era, LED technology is still in rapid development and change, we need to calmly think: What kind of position do we need in the LED lighting 2.0 era, so what do we need to do now?
