LEDinside visited the former chairman of Guolian Optoelectronics Co., Ltd., and now serves as the chairman of Lianjia Optoelectronics and Liansheng Optoelectronics, Dr. Huang Guoxin, and Lianjia Optoelectronics General Manager Huang P P Xianxian, mixing the current situation and future development of Lianjia Optoelectronics Group. direction. At present, Lianjia Group has formed a complete supply chain in the LED industry, including Liansheng Optoelectronics of the upstream epitaxial, Lianxinfeng of the midstream package, and Lianjia Optoelectronics of the downstream products and channels.
The subsidiaries of Lianjia Group have a good performance. Lianjia Optoelectronics has made great gains in the traffic light and Christmas lights market. The Christmas light products have been successfully cut into the supply of American hypermarkets, and the LED traffic lights are in the world. 270KK's LED number lamp market also has a place. The upstream Liansheng Optoelectronics continues the R&D energy of the former Guolian Optoelectronics era (the National League later merged into the crystal power), and will launch the æ•£çƒ-substrate-type blue LED chip with better heat dissipation in the second half of 2009, which is the third in the world to develop the ruthenium substrate. LED manufacturers, in the future, Lianjia Optoelectronics will use its own 矽 substrate LED to enter the field of street lighting.
Lianjia Optoelectronics: the first brand of LED traffic lights
The main products of Lianjia Optoelectronics include the modules of Christmas lights, horn lights and car lights. Lianjia Optoelectronics is strategically unwilling to compete with most LED manufacturers in the Red Sea for backlight applications. Instead, it focuses on the inconspicuous Christmas lights and the traffic light market. It has mastered the key brands and channels and found another blue ocean.
Lianjia Optoelectronics has a high market share in the traffic number, and its market share in Taiwan is as high as 60%. And what is the size of the traffic light market? Chairman Huang Guoxin said that there are currently more than 9 million intersections in the world. There are 4 directions for each intersection. In the case of positive or negative, there are 8 sets of traffic lights, and an average of 30 LED lamps (red, yellow and green). , plus pedestrians, around and so on). If the average luminaire is calculated at $30, LEDinside estimates the global LED luminaire market. If it is completely replaced by LED luminaires, it will be about $8.1 billion. With the current energy policies of various countries, the room for growth can be expected.
LED traffic lights must be exposed to the outdoors for a long time, so the reliability and longevity of the product is very important. Generally speaking, the traffic light product is changed once every five years and the warranty is also required for five years. Lianjia has a very early layout in the traffic light market, so it has long measured data and is more advantageous in the competition of international standards. In addition, traffic lights are also very important in optical design. Since there are about 44 points on the traffic light, there are different heights and directions for pedestrians or driving, so the optical design capability is also very high. important. Since each region has different requirements and specifications for traffic lights, how to quickly cooperate with the customer's customization ability is the competitive advantage of Lianjia Optoelectronics in the traffic light market.
In the near future, Lianjia has also developed a high-power LED slogan. At present, the United States has applied specifications for high-power LEDs for traffic loyalty lights. Currently, there are not many LED manufacturers that can provide specifications. Since the high-power red-yellow LED brightness can be increased to 20 or 30 times, the number of LEDs used can be greatly reduced, so future high-power LEDs will gradually be applied to the market. However, the price difference between high-power LED traffic lights and general LED traffic lights is not great. In the future, the increase in penetration rate of the former will be driven by regulations to a certain extent.

Liansheng Optoelectronics: the world's third mass production plant for substrate-type LED
Focusing on the upstream epitaxial products of Liansheng Optoelectronics, the technical team is from the former Guolian Optoelectronics. The main products are mainly quaternary red and yellow LED chips. Due to the competitive advantage in cost, the market share is over 50%.
As for the blue-green optical chip, Liansheng has developed a blue- and green-light chip of the substrate type, which is the third in the world after OSRAM and CREE. At present, the mainstream technology of epitaxial manufacturers, blue LED is a sapphire substrate crystal, although the sapphire substrate has good light transmission, but the heat dissipation is not good. Therefore, the key technology of Liansheng is to cut the sapphire substrate into a ruthenium substrate after completing the crystal growth.
At present, Liansheng Optoelectronics has developed the world's brightest green LED with 505nm wavelength using 矽 substrate LED, and the blue LED chip of 矽 substrate is also expected to be mass-produced in September.
Chairman Huang Guoxin said that the heat dissipation and reliability of the ruthenium substrate is better than that of the sapphire substrate, which is suitable for LED street lamps that require excellent heat dissipation. In addition, Lianjia, which is responsible for the products, will use the products of Liansheng to manufacture street lamps and Traffic number lights.

LEDinside view
Chairman Huang Guoxin believes that the research and development budget invested by Taiwan LED Company is still too small. Taiwanese manufacturers generally use mass production, fight costs and fight management. However, when each industry has improved its management capacity and cost to a certain extent, it is still Will face the problem of overcapacity. Therefore, the importance of taking root in technology is especially emphasized.
LEDinside observes the business model of Lianjia Group and masters the technology and access to the core competitiveness of the company. Although the LED industry is very large in scale, there are many competitors. In a highly competitive environment, excellent technical capabilities are already one of the prerequisites for competition. At this stage, LED manufacturers have their own skills. After the technology has progressed to a certain extent, the key to profitability is to master the brand and the channel, and to master the brand and the channel's estuary to avoid the price competition. Therefore, the LED industry should be able to avoid the dilemma faced by Taiwan's two-megabit double-star industry at this stage.
