First, China’s semiconductor lighting digitized current development
(A) The central government attaches great importance to the development of energy-efficient lighting industry
To accelerate the semiconductor lighting technology progress and industrial development, according to “Long-term Scientific and Technological Development Plan (2006-2020)”, “the State Council on accelerating the cultivation and development of emerging industries of strategic decision” and the “national” five “scientific and technological development” and other relevant requirements, the ministry on July 3, 2012 issued a “semiconductor lighting technology development,” second five “special plan.
“”Special plan” that should apply to seize the commanding heights of innovation as the goal, process innovation, system integration and solution-focused, developed with cost-competitive semiconductor lighting products to replace inefficient lighting products. Focus on intelligent, networked LED lighting system development, including: reducing lighting energy management and maintenance management costs of system integration technology research; lighting system network topology and network performance optimization technology; cloud-based Internet and public lighting management system development; things based semiconductor lighting control systems, and energy management systems development; lighting system with residential, office buildings, and transportation control system combines integrated approach and technical research.
(Two) needed to implement the policy foundation
Currently semiconductor lighting market prospects, the government introduced various support measures, large capital inflows. Policy was enacted to regulate and guide the market, but the policy issued to the specific implementation, with the distance of space and time. The market has been changing in so there will be policy-oriented and market demand there is a deviation of the situation, which is not in place to implement the policy one of the reasons.
Ministry of Finance, Development and Reform Commission, Ministry of Science and three ministries jointly undertaken semiconductor lighting products financial subsidies to promote the project, due to the existing technology is not yet mature, public awareness is low, the cost of production higher negative factors, the enterprise technology, product and service level varies greatly, industrial chain to be further improved and other reasons, temporarily unable to achieve the desired effect of the promotion and application. The lack of policy support conditions, positioning is not accurate enough. As the market is not mature enough, so that the unit has shelved plans to use programs such as subsidies, so hesitant units continue to wait, thus delaying the application of the scale of the market’s healthy development, and even vicious competition.
Industrial development should take full account of the guiding ideology of the basic conditions for industrial development of the market will have to take full account of the actual demand. Any goals, targets, tasks, content settings must eliminate empiricism, to have efficient and effective safeguards. General lighting market maturation and development of policy support in addition to this factor, should also follow the development of the market, only a low-carbon society, environmental awareness into the Chinese people’s hearts and change people’s ideas, in order to promote the healthy semiconductor lighting industry healthy development.
(Three) increasing social demand
As society advances, in recent years, semiconductor lighting technology has come to the people’s lives in the past, toward a higher luminous efficiency, better luminous quality, lower cost, more features, more reliability and a wider application of direction . The realization of digital lighting, effectively changing the traditional concept of lighting people, the lighting in the area of product application systems, maintenance systems and advanced management system elevated to a new height, opened a new chapter in the history of lighting. For the situation is now speaking, China’s large public buildings lighting function is dependent on the support of various lighting equipment, requires a lot of manpower and resources to maintain. But managers commonly used regular maintenance mode less than ideal, the urgent need for an integrated management of the effective ways to change this status quo.
From the point of view of energy conservation, many hair up State / Territory governments have arranged a special fund, set up a special program to develop a strict incandescent phase-out plan, and vigorously support national and regional semiconductor lighting technology innovation and industrial development . Semiconductor lighting industry has become an international strategic shift in the direction of large enterprises, patents, standards, talent competition heated up, industrial development was the explosive growth. R & D investment in the country’s continued support and market demand, China’s semiconductor lighting technology innovation capability has been rapid increases in functional lighting energy-saving effect is already apparent. With urbanization, consumption for lighting products will further increase, increasing pressure on energy conservation, need large-scale application of semiconductor lighting energy-saving products. Therefore, an urgent need to have energy efficient, advanced and convenient management system, dramatically reducing the cost of management and maintenance of digital semiconductor lighting products to meet the needs of society as a whole.
Second, the digital semiconductor lighting products debut
In 2009, the semiconductor functional lighting products into the overall application of large public buildings, which marked China’s semiconductor lighting from the outside into the interior, from the non-functional lighting developed into functional lighting to achieve a first semiconductor lighting across , opened a new chapter in the history of lighting.
2012, the birth of semiconductor lighting industry a new milestone. First overall application of semiconductor functional lighting products gratifying results after three years of operation, the user units strict inspection results show that more than 20% increase mall illumination, energy-saving rate of 70%, the failure rate of less than 1%, the light fades less than 20% the indicators are in line with national, industry and user requirements.
2013, semiconductor lighting a steady pace into the digital era, digital semiconductor lighting system in the country “Three Green Project” demonstration project debut, forming a third semiconductor lighting industry spans. The project through the network management platform software CNC semiconductor functional lighting with a combination of hardware, the original tradition of the overall transformation of efficient lighting digital semiconductor lighting to achieve a time-sharing basis for lighting, partitions, automatic control; lighting equipment on-line operating conditions monitoring and management; and lighting systems with energy metering. This is the digitization and digital lighting management means an overall implementation, is the first large-scale use of the lighting industry by means of intelligent management of large public buildings for energy-saving lighting and management, China’s semiconductor lighting industry is another milestone.
Third, the semiconductor lighting industry into the digital age
(A) semiconductor functional lighting is an extension of the digital semiconductor lighting
The 21st century is the era of digital technology, digital technology has brought people to facilitate the efficient and increasingly high demand, the salient features of the present era is the digital lifestyle. With the rapid development of semiconductor lighting technology, its application has access to digital, intelligent era of digital lighting control needs more and more clear, digitization, networking and remote monitoring and other technical means of lighting systems has become the standard configuration . Semiconductor lighting experiencing the initial stage of decorative lighting and outdoor lighting, functional lighting intermediate stage, the development of digital lighting stage. With digital technology is becoming more sophisticated lighting, LED lighting and digital lighting combined, will give people ideas and illumination lighting to bring a new revolution.
Semiconductor functional lighting fixtures for lighting terminals, and the number of semiconductor lighting contains a monitoring system, a communication unit, a control module and a semiconductor functional lighting. See Chapter.
(Two) the advantages of digital lighting
Semiconductor functional lighting fundamental research is only a lighting fixture, depending on the requirements of matching the corresponding fixture to meet the demand, but does not support management system for monitoring, control and management. Observed only by artificial lighting system running, not easy to manage and maintain, unable to detect a fault condition occurs, can not guarantee their normal life. Therefore, the semiconductor functional lighting is only available on specific, small, easy maintenance and overhaul of functional lighting environment, unable to meet the large public buildings, factories, mines and workshops such as the need for large-scale application of integrated management of lighting environments.
With the rapid development of LED technology, the field of digital lighting and remote monitoring needs more and more clear, digitization, networking and remote monitoring has become a standard in lighting technology, semiconductor lighting applications blindly from the past into the pursuit of the luminous efficiency of digital , intelligent era. Whether in color performance ability, the ability to control lighting or energy-saving and environmental protection sectors, or in the condition monitoring of sophistication, ease of maintenance system, and better than ordinary semiconductor functional lighting has obvious advantages.
Digital semiconductor lighting fixtures terminal has operating conditions data acquisition, data upload, accepts PC remote control functions, the number of applications is not much lighting effects can be unified for the entire lighting system for monitoring, control and management for large architectural lighting and management to truly achieve a high level of quality and energy efficient lighting effects.
Promote the use of large public buildings digitized lighting, through remote monitoring of equipment to improve the level of automation equipment management, reduce equipment failure, to achieve normal equipment life, reduce production and management costs, optimize energy use and improve energy use metering measures to rationalize energy drop consumption, to achieve large-scale public construction equipment running stop management. Digital content is unusual semiconductor lighting technology in the semiconductor functional lighting, because of its hardware and facilities, products and strong self-test function, high transparency, it is difficult to fish, may lead to some industry lack of core competitiveness of enterprises is difficult to maintain.
Fourth, the industrial development needs analysis
(A) digital semiconductor lighting industry chain is difficult to naturally formedDigital semiconductor lighting industry chain, including upstream epitaxial wafer manufacturing, chip manufacturing midstream and downstream LED packaging, digital intelligent control systems, lighting and other aspects of the application. Upstream of the high technology, capital investment, quality, high-impact, high profit margins for the entire digital semiconductor lighting industry is extremely important. The middle reaches of technology and capital-intensive sectors, the chip is currently the most competitive part of the patent, with investment intensity but slow effect characteristics. Packaging and lighting applications are digital semiconductor lighting industry chain downstream part, is a direct link with the market closely. Part due to the application of investment required is small, lower barriers to entry, the application of product variety, semiconductor lighting industry is the largest and fastest-growing fields.
Digital semiconductor lighting become the future mainstream of the field is illuminated outside the industry consensus, but blindly follow the trend of investment, expand production capacity can not form a complete industrial chain of health. Manufacturers need to strengthen, establish and improve the development, production and testing system, to fully understand standards, understand the use of ambient lighting requirements, understanding of user needs, but also need to improve the core competitiveness of industries to enhance the competitiveness of their products.
(Two) the need for government guidance and support
Eighteen major report proposed a “new four modernizations” which contains new ideas, new thinking, new ways, new structures. “The new four modernizations” What is new in the highlights “information.” The so-called information technology, refers to the culture, the development of digital, intelligent representative of the new productivity tools, and make it the benefit of society historical process. In our country the “new four modernizations” construction process, the core content is the use of advanced technology to promote industrial, social progress and development of the city, the development of digital lighting technology of the “new four modernizations” building has an important positive role.
An emerging industry can not develop without the support of national policy, it is because we see the semiconductor lighting industry immeasurable future prospects, governments support the policy does not lose each other, and today, China’s semiconductor lighting industry did not meet expectations effect, because it is extremely complex. First, China’s investment environment prone government under the guidance of the investment boom, which in photovoltaic, wind power investment may slightly miniature. Compare other countries’ development model, America’s core line is “driven by the market through technological breakthroughs, accelerate the market penetration speed”, by controlling the core technology, market profits hold steady flow of about 80% of the industry profits obtained. At this point, the United States and the largest producer of LED first Japanese coincide, and both have chosen to focus on basic technology research and development, which is sorely lacking in our country is the development of an attitude or basis points.
Development of digital semiconductor lighting from national policies, government policy departure, seeking industry and government policies butt to better and faster development of China’s semiconductor lighting industry digitization. Only through the government on a variety of social integration and utilization of resources, the formation of the relevant research institutions, expert in-depth investigation and analysis of the case, the government policy and financial support given and carried out, thus leading digital semiconductor lighting industry developed steadily.
(Three) semiconductor lighting products manufacturers struggling
Although the Chinese government on a grand scale semiconductor lighting industrial bases rally, but financial support and access to finance expansion and obviously stretched, it is difficult for the industry to pave the way for future development. Therefore, the current semiconductor lighting industry funding bottlenecks to be solved. Due to the double whammy of policy and market, has been eliminated small scale, weak competitiveness of the core semiconductor lighting company, but most companies are still blind due to capacity expansion and product sales into trouble, resulting in deficits, cash flow problems, and even has face closure. If you do not get rid of low-price competition on innovative design model, the domestic LED photovoltaic industry may soon face the dilemma.
Guangdong is China’s LED lighting industry’s first city, but the rise of new industries not yet fully appeared signs of excess capacity, one is in Shenzhen has four billion dollar level enterprises face closure due to funding strand breaks, on the other hand substantial investment is still flocked. Stir beneath, LED industry is destined to continue to struggle in torment.
Competitive pressures in the market, the semiconductor lighting industry in order to truly break through the bottleneck, the right to speak on the market, it must have a strong technical advantage, and has its own independent intellectual property rights and core technologies to be able to have development potential. Although the semiconductor lighting enterprise innovation much faster than expected, but still huge room for improvement.
