In the summer of June, the LED industry entered the finals. In the price war, mergers and acquisitions, the tide of closure, and the fierce battle of e-commerce, who can dominate? When the traditional LED package form becomes mainstream, is the new wave of mainstream fifth-generation light source LED filament? Is the power of LED companies flipping?
The industry integration pattern began to visit more than 20 LED industry-related pavilions at the Guangya Exhibition, interviewing more than a dozen senior executives who were in the forefront of the entire industry chain. For the price war, mergers and acquisitions, and the tide of closure, the big cafés are very calm. They all believe that this lighting demand continues to grow, but too many manufacturers have become a pain in the industry. The global LED chips will continue to be consolidated, but the previous industry consolidation is mainly vertical, and then the level will be the main. It is an inevitable trend that the entire industry is the largest.
Wang Donglei, chairman of Dehao Runda, said that the development stage of the LED industry is now equivalent to the home appliance industry in the early 1990s. The competition for the industry has just begun.
The lighting market is up, but the price continues to decline. It takes some time to replace the traditional lighting phenomenon, but the lighting is still growing overall. LED lighting technology still has a lot of room for improvement. The low-priced products in mainland China made everyone have no confidence in lighting. After the factory used quality and technology to attack the market, domestic companies also converted the concept of price war into quality. Lord, the price is supplemented, and the two complement each other.
According to the industry's big coffee, the realization of the downstream lighting industry's industrial chain is basically impossible. Because of the development of traditional lighting, the global market share of Philips' current lighting market with the largest market share is less than 3. The so-called big Hengda and oligarchy are confined to the middle and upper reaches.
LED filaments have become the ban on the ban, and incandescent lamps will be withdrawn from the market. The traditional LED light source is designed around LED lights that are 180 degrees bright. The illumination angle is always not ideal. Since the chip can be packaged on the bracket, in theory, it is also feasible to directly package the chip on the filament-shaped substrate, which promotes the rapid birth of the LED filament lamp, and also because of its characteristic of nostalgic incandescent lamps.
Relative to the entire LED industry is undoubtedly a good news, it is also an important transformation opportunity for traditional incandescent lamps manufacturers. This has also contributed to the cooperation between Baishi Optoelectronics and Chengdu Tianxing Lighting. At his meeting, Wang Peng, general manager of Baishi Optoelectronics Marketing Center, told the author that there are two major development directions for LED filament lamps in the future. One is to replace the market of incandescent lamps, and the other is to go to high lumens and high power. development of.

In addition, from the existing commercial and industrial fields to the civilian sector, energy conservation and emission reduction are implemented in residential indoor lighting, and the development of LED filament lamps coincides with the time. The emergence of LED filament lamps has a revolutionary significance. As long as it breaks through the technical bottleneck and lowers the cost price, the impact on the LED lighting field will gradually increase in the future, and it meets the needs of some nostalgic people. This part of the market potential is considerable. Baishi Optoelectronics and Tianxing Lighting will exert their strength in this field and occupy part of the market.
Flip-chip will monopolize the high-power market in the future. From last year to this year, the flip-chip LED chip technology with the advantages of improving luminous efficiency, improving heat dissipation and reducing the cost per lumen can be considered a real fire in the LED industry. When.
At this Guangzhou Lighting Exhibition, Jingke Electronics, Jingyuan Optoelectronics, New Century Optoelectronics and other manufacturers have exhibited products of flip-chip soldering chips.
It is understood that many years ago, many companies have been implementing the technology and research and development of flip-chip chip, and Philips Lumen has used flip-chip solder chips in large quantities seven years ago, but it has been lifted in the market. Only the Jingke Electronics Group is the mainstay of the welding technology banner, while other manufacturers are relatively low-key despite the launch of related products.
Jingdong Electronics President Special Assistant Song Dong said that compared with the formal and vertical structures, the use of flip-chip welding, it is easier to achieve ultra-high power chip-level modules, multi-function integrated chip light source technology, LED chip module yield And performance has a big advantage. Moreover, Flip-chip has a good heat dissipation function, and has the advantages of low voltage, high brightness, high reliability, and high saturation current density.
Taiwan's leading chip company, Jingyuan Optoelectronics Co., Ltd. is also the mainstay of the flip-chip welding technology. The partner of the marketing and marketing center of Jingyuan Optoelectronics Co., Ltd. Lin Yida personally went to the booth to scream for the recommended flip-chip solder chip this year. Teach customers how to use flip chip bonding technology.
Lin Yida said that flip-chip welding technology can greatly improve the stability and quality of the product, with larger solid crystal welding and higher past current, the value of lumens per watt will be greatly improved.
Yang Shiyi, the person in charge of the new century optoelectronics, said that the new century optoelectronics has also introduced flip-chip welding technology three years ago, but the market promotion was very rare at that time. Today, more companies are finally pushing this technology, the market accepts. The degree has also been greatly improved.
Zhao Sen, general manager of the sales department of Guoxing Optoelectronics White Light Devices Division, said that flip-chip soldering chips are definitely a market trend in the future, and will also affect the traditional packaging process, but the current volume is relatively small, the cost It is also relatively high, so there is no high-profile publicity in this regard.
Zou Jianqing, sales manager of Shenzhen Tiandian Optoelectronics Technology Co., Ltd., said that Tiandian Optoelectronics also introduced new products for flip chip soldering technology. Its advantages in terms of high power are unquestionable, and the orientation of later chips will definitely Develop in this direction.
Chen Haishan, director of the Advanced Marketing Department of Cree China, said that the direction of various technical routes, such as dressing technology, flip-chip welding technology, and package-free technology, is all in order to resist the smaller LED chip area. Driven by larger currents for higher luminous flux and thinner characteristics for better performance.
