Advanced Photoelectronic Technology Co., Ltd. (AdvancedPhotoelectronic Technology Ltd.) uses its core technology advantages to invest in the LED industry chain from the mid-stream chip position, while crossing and saving the traditional LED packaging process and cost, directly to the high-power, ultra-high power module Chip products are available to downstream lighting source customers. 10 invention patents in the United States and China, and continuous technological innovation at the rate of applying for 2 invention patents per year, with wafer-level flip-chip bonding technology, eutectic tin bump technology, lead-free tin bump technology, gold bump Point technology, flip-chip high-power chip manufacturing technology and multi-chip integration technology, Aladdin Lighting Network interviewed Dr. Xiao Guowei, CEO of Micro-Crystal, to share the success and industry trends of micro-crystals with industry friends and customers. Latin Lighting Network allows more netizens to understand the high-power chip makers from Hong Kong.
Can you introduce the development history of APT and the company's development history?
From the very beginning, we have focused on the technical development of high-power LEDs and high-brightness LED epitaxial chips. Especially in the past three years, our product technology has improved very fast. The luminous efficiency has grown from the initial 40 lumens per watt to the present 110. With lumens per watt, laboratory data can reach 120 lumens per watt. This is very leading in the domestic brands.
Our company's development-oriented market is high-power and high-brightness LED chips in semiconductor lighting. We often have our own intellectual property and core technologies, and we have a complete technical team. The entire company's investment has grown from less than 10 million US dollars. The registered capital is now $23 million and the total investment is $50 million.
Our main products are blue LED chips from 0.5W, 1W to 3w for white and commercial lighting. In addition, the proprietary technology of Micro-Crystal is module chip technology, which is the high-power flip-chip LED chip technology developed by us. It can realize 5W, 10W and 20W modules, which can be directly supplied to downstream LED manufacturers. . The customer group that is directly facing now is a high-power LED packaging enterprise and is applied in functional lighting, such as LED street lighting and LED indoor commercial lighting.
At present, LED itself has some problems, such as heat dissipation and light decay. Many LED lamps, especially LED street lamps, use a single 1W light source. If you use LED module light source, isn't it better to solve the heat dissipation? Where is the advantage of the module light source?
This question is very good. In fact, these two technical routes are not contradictory. So far, we still choose whether the light source is a single 1W package or a module light source package according to the customer's environment and the requirements of the lamps. Form, I believe that these two technical directions are complementary.
But with the advancement of LED chip technology, you can imagine that when the luminous efficiency is increased by 10%, the heat problem is actually reduced by 10%. The development of LED chip technology is quite rapid. When the luminous efficiency reaches 130 lumens per watt-150 lumens per watt, the heat is getting less and less, and the heat dissipation problem becomes more and more easy to solve. In fact, the middle and upper reaches are mastered. The core strengths are also here. Through technological advancement, downstream packaging and LED lighting application manufacturers will not encounter too much difficulty in application and heat dissipation and do not need to make too much investment.
The development of the LED industry, in fact, the middle and upper reaches of the enterprise is controlling the ultimate core power and technology. My view is that when the luminous efficiency of the LED chip reaches 130 lumens per watt, the application of the module light source will become larger and larger. Because with the improvement of LED luminous efficiency, thermal problems and other series of problems have become less serious. Of course, the application of the module light source is not a simple assembly of imagination, in fact, it is the added value provided by the chip enterprise, and the module is designed for the end customer. From the beginning of the chip to provide optical, electrical and matching solutions, which is what we call ODM, this is the first proposed by microcrystals. I was talking about this thing two years ago, and this matter will soon become a bigger market reality. Jinko Electronics hopes to cooperate with more packaging and lighting manufacturers in the future, and design special module light source chips according to our upstream technical advantages and customers' different needs. In this way, I believe that the promotion of LEDs in the lighting market will be faster. Module light source technology and chip light source technology are also the first in the industry, because our high-power flip-chip LED chip technology combined with integrated circuits and system integration can provide 0.5W of single crystal. , 1W light source, can also provide polycrystalline modules and light sources, and has integrated functions according to customer requirements for packaging and application manufacturers.
In fact, there are not many LED manufacturers that use module light sources. LED street lamp manufacturers choose more single-light sources. How does Jingke respond to the challenges of LED street lamp manufacturers?
As an upstream manufacturer of LEDs, it is the largest support and help for downstream enterprises to provide cost-effective and high-performance products. This is precisely what companies with good capital and technology investment like Jingke can do. It can be said that the chip and module light source of Jingke can achieve more than 20% improvement in light efficiency every year, which can meet the continuous growth of the market, and the cost of our products continues to decline. We believe that our products cost-effective in China. It is in a leading position, which is the biggest cooperation support we can do with our customers.
As for the LED lighting market, whether it is a single crystal source or a modular one, it is a technical route. I always think that the two are not exclusive. There is no need for them. They are a dynamic process of change. . That is to say, with the advancement of LED technology, the importance of single crystal mode LEDs may decrease, and the modularization will increase. However, if the modular light source is used too early, it may not be able to play the role of the LED module due to heat dissipation problems and other series of technical problems or cost problems, so it is necessary to dialectically look at this matter.
Some people will be entangled in this issue. In fact, there is no simple good or bad for a single LED light source and a module light source. It is a prerequisite. Microcrystals were the first to develop modular light sources, and Jingke Electronics will be mass-produced. We have not rejected any of them. We now have single crystal wafers for sale, and there are also polycrystalline modules for sale. This can only be chosen by customers and the market. You can't just rudely divide who is good or who is bad, but also depends on the final application. As for LED In terms of the street lamp market, more upstream and downstream and industrial chain systems are needed. For example, whether the power efficiency can be improved, whether the heat dissipation efficiency can be improved, and whether the cost of the whole lamp can be reduced. In this case, the chip manufacturers have already done Very work. At present, there is a set of data to illustrate that in the LED street light, taking the Jingke LED chip as an example, the price of the LED chip in the cost of the LED street lamp is less than 15% (the general data is about 1/3, about 33). %)
At present, it can be said that the manufacture and core technology of LED chips are in the hands of European and American companies, Japanese and Korean companies, so what kind of planning does Jingke have in the future, how does Jingke find its own survival point?
The development of a company must be based on the present and the future. We have such planning and confidence to be a national brand. At the same time, the biggest advantage of Jingke is that we have the technological development capability of independent and innovative technology core. Second, we make good use of the market in mainland China, do a good job in sales, marketing and services, better close to terminal and lighting application companies and customers, provide better sales services, and provide higher and better competitive products. In this way, I believe that there is room for us to develop and rise and the city is often
In Taiwan and Japan, the trend of developing LED TVs with high-power backlight modules has emerged. Backlight module companies have begun to use medium power, and high-power backlights have been used in Japan like Sony, with cost reduction and performance improvement. The use of medium-power modules as backlights is a trend, and precisely because of this, including Jingke Electronics, seeing this, I believe that our development and growth rate will be very huge in the future.
What is your evaluation of the current LED industry development trend?
For the development of the LED industry, there are several points that are relatively clear. As a high-tech development enterprise, there is never a maturity period. If it is mature, it has become a stable industry. The development of high-tech development industry is characterized by fast, this is a good thing, but it is indeed from my personal point of view that it is necessary to cool the LED. This industry is very hot. It is not good to be hot. It is not good to overheat the industry. Rather, it is said that all kinds of forces will not follow the normal high-tech market and laws, leading to chaotic development of the entire technology and market. As a government guidance, this time needs to be very important and critical. The role, the so-called extremes must be reversed or destructive, this kind of thing will appear in some high-tech industries, then the development of the LED industry seems to me to be at least a normal healthy development process, and in the next 5-10 years LED he still It will continue to develop, so it is not possible to achieve the best of both worlds, so we must always follow the laws of technology and market development. At this time, as an upstream and middle-end LED company, I personally made LEDs for so many years. In some blind introduction or catalytic methods, LEDs should be properly cooled down. In the benign market guidance or government investment, the LED industry still needs government policy support. If the development of this industry is relatively healthy, I believe that in the next 3-5 years, the market scale and technology upgrade will show a geometric index growth. But then again, it is necessary to properly cool down and stop to see what is right and what is wrong, which ones can be done now, and which ones need to be done in the next 2-3 years. This is the most important.
As an upstream LED manufacturer, what advice do you have for companies that want to enter the LED industry?
There are many entry points for the LED industry. There are more terminal applications and downstream markets. The most important thing is to have core competitiveness, to create their own added value in the industry chain, and to build their own brands and realize the upstream and downstream integration of the industry. It is very important. If it is just a single entry point, it is very difficult to develop independent products or simplistic repetition, imitation, and counterfeit mode development in the LED industry.
We are currently looking at the LED industry as a stable growth market, and our investment is based on autonomous core technologies. From the perspective of overall economic development, the future development tends to be stable, but there may be some twists and turns in the middle, but there is a general trend that is constant. With the development of society and technology, human consumption of energy Demand and consumption are getting bigger and bigger. Green energy and green lighting will be the eternal theme in the next few decades or even hundreds of years. A sustainable technology and industry will certainly have a good development prospect. The LED industry is such an industry and technology. As the person in charge of the enterprise, this should be seen. The prospects are very good, but the overall economic fluctuations, including the financial tsunami or some future economic impacts, in the final analysis, must have core competitiveness for enterprises. Core technology, this is the law that will never change for the high-tech industry.
Of course, in the end, Mr. Xiao Guowei hopes to use the platform of Aladdin Lighting Network to show that: Jingke Electronics provides LED chips and module light sources in the LED industry chain for the majority of users, especially for the terminal engaged in green lighting and energy saving and environmental protection industries. The industry chain and partners provide good technology and products. As a mid-to-highstream enterprise, we are willing to work together with terminal lighting companies and application manufacturers to promote the continuous upgrading and renewal of the LED industry.
