The LED lighting industry is currently facing a serious crisis of overcapacity, homogenization competition and low-price competition. The LED industry chain needs to be developed. Therefore, the development of new, stylish, high-quality LED lighting fixtures will be a major topic for future research, with high added value and output value, we must pay attention to it from now on.
LED industry development is divided into two stages
The first stage of LED development has low luminous efficiency, and the efficiency of the second stage continues to increase.
The LED industry development is divided into two phases. The first phase is from 1968 to 1999. It is the growth stage of the LED industry. The product features low luminous efficiency and is mainly used for signal and display. The second phase is from 2000 to 2020. It is the development stage of the LED industry, and the product efficiency continues to increase, from 15 lm/W equivalent to incandescent lamps to 258 lm/W, exceeding all existing electric light sources. Its range of applications extends to the field of lighting until it becomes the protagonist of the field. Due to the leadership of technology development and the gradual expansion of the market scale, the total scale of the LED industry has increased tenfold or even 100 times.
Adjustment to the semiconductor lighting industry chain
Under the new situation, the LED industry chain must be adjusted to the semiconductor lighting industry chain. In the first stage of the development of the LED industry, the structure of the industrial chain is relatively simple, which is what we usually call the upstream, middle and downstream industries of LED.
In the second stage of LED industry development, LED luminous efficiency continues to increase substantially. In addition to further development in the original signal and display fields, the application is gradually expanding to the lighting field. By 2012, the efficiency of LED devices will reach 130lm/W, which can not only replace incandescent lamps, halogen lamps, but also fluorescent lamps (including compact fluorescent lamps). The scale of the industry has increased significantly, especially in the lighting application market. A typical example is the sale of 20 million LED bulbs in Japan in 2010 and sales of 35 million in 2011. The European spotlight and PAR light market started, North American downlights and bulbs started, and Chinese LED street lights started. People called 2010 the first year of LED lighting. LED lighting applications will develop rapidly. Under the new situation, the LED industry chain will have to be adjusted to the semiconductor lighting industry chain.
The structure of the semiconductor lighting industry chain has developed into an inverted triangle. From the data of the global semiconductor lighting industry chain in 2010 and 2020, we can see the following five development trends: First, in 2010, the whole industry chain is a small diamond with two small heads in the middle, which is extremely abnormal. The healthy industrial structure should be For example, the reverse triangle in 2020, the export of an industry should be large; secondly, the total output value of the whole industry chain will increase by 53 times in 2020 compared with 2010, and the growth rate is very fast; third, the largest increase is the intelligent control of LED lighting. Engineering, more than 700 times; Fourth, the second increase is the lighting fixtures, 30 times in 10 years, again LED package, 25 times in 10 years; Fifth, from the output value in 2020, lighting system The output value is almost four times that of LED packaged devices.
There are several views on the development of the semiconductor lighting industry chain:
First, continue to develop materials and device production based on the initial establishment of a complete industrial chain. It is the foundation of the industrial chain, and its first growth will promote the sustainable development of downstream industries. Under the prospect of expanding the output value by more than 50 times, we will strive to develop manufacturing and testing equipment, especially MOCVD equipment, and vigorously support the priority use and promotion of qualified products, and strive to use our own equipment in the next wave of development.
Second, in the initial solution to the quality, life and market of LED light sources, increase the research and development of lighting fixtures. Combining energy-efficient light sources, quality lighting and culture and art will be an eternal theme. Like cloth and fashion, fabrics will be eliminated and developed, and no matter what fabrics, fashion will keep up with the times, long-lasting, and even 30 years. Providing high-grade LED lighting fixtures can be done now, and many of the advantages of LEDs provide more room for innovation in lighting fixture design.
Third, the biggest development should be lighting services and system solutions, or intelligent lighting system control engineering. Modern technology provides us with sensors, network technology, wireless communications, and other hardware and software conditions that we can build. LEDs can be dimmed, toned, and integrated with integrated circuits in a system. The development of LED display technology and landscape lighting technology has provided us with a direction and can generate secondary energy saving benefits. We used a mobile phone or computer to switch outdoors or regulate home lighting a few years ago. This year we saw experimental prototypes at the show. It is said that products will soon be sold. The energy-saving, environmentally-friendly and beautifying life of LED lighting will be carried out on a larger scale in a wider field.

A PON consists of an Optical Line Termination (OLT) at the communication company's office and a number of Optical Network Units (ONUs) near end users. Typically, up to 32 ONUs can be connected to an OLT. The passive simply describes the fact that optical transmission has no power requirements or active electronic parts once the signal is going through the network.
N-NET supply Ethernet Passive Optical Network (EPON) and Gigabit-Capable Passive Optical Network(GPON),EPON and GPON are popular versions of passive optical networks (PONs). All PON systems have essentially the same theoretical capacity at the optical level. The limits on upstream and downstream bandwidth are set by the electrical overlay, the protocol used to allocate the capacity and manage the connection.
