With the development of global communication technology and the explosion of the smartphone market, the market demand for flash lamps is increasing and the requirements are getting higher and higher. In order to meet the market demand, domestic and foreign manufacturers have shifted their research and development focus to LED flash lamps with longer life, more energy saving and higher performance. However, researching LED flash lamps is not an easy task. It is a "hard nut" that requires a lot of effort.
Foreign giants "monopolize" technology and it is difficult to find cooperative customers
LED flash has been developed for nearly ten years. The current market structure is basically dominated by four major manufacturers including Philips Lumileds, Osram, Everlight Electronics, and Samsung. It is divided into two camps, namely Osram, Cree, and Samsung that use vertical structures, and Philips Lumileds and Nichia that use flip-chip structures. With the rapid growth of the mobile phone market, Taiwanese manufacturers Epistar, New Century, and Lite-On are also rushing in. LED flash supply chain. Among them, Everlight's Flash LED products have captured a lot of market share in mainland China, driven by their entry into the smartphone supply chain in mainland China.
Faced with the huge cake of LED flash, domestic companies are unwilling to give up to others and have invested in research and development in order to get a share of this emerging market. However, this process of tackling key problems has not been smooth for domestic companies, and many companies have been blocked by technical and market barriers. Since LED flash is a high-profit product, major international manufacturers closely protect this market segment, and it is difficult for domestic packaging plants to break through this technical bottleneck. In addition, high market barriers also make it difficult for fledgling domestic companies, because even if they make qualified products, the costs are difficult to compete with mature products on the market.
As Zhou Xuejun, marketing director of Philips Lumileds, said: "It is indeed very difficult for domestic companies to break into the supply chain of mobile phone manufacturers. On the one hand, LED flashlights have very high technical requirements and no mistakes are allowed. On the other hand, mobile phone manufacturers will not easily replace already installed ones. With stable parts suppliers.
Ou Weineng, product director of Jinko Electronics (hereinafter referred to as Jinko), also has the same concern: "To enter the flash market, the product must meet high performance requirements and be stable and reliable for a long time. In addition, flash is mainly used on mobile phones and belongs to a different industry from the display, lighting, backlight and other fields that domestic LED manufacturers are accustomed to. Clients need time to understand domestic LED companies, and there is a process for product certification introduction." ”

Continue to fight and face difficulties
Technology is difficult to attack and customers are hard to find. These have repelled the desire of many domestic LED companies to attack, but in the eyes of Jinko, they have become motivation. Ou Weineng said: "Flash requires high performance, stability and reliability, and at the same time, it must consider matching with optical lenses. These have put forward a lot of requirements for developers. Although there are many difficulties, Jinko is ready for long-term operations." ”
Jinko Electronics, as the only domestic Companies that can mass-produce "gold-wire-free packaging" products and have been in mass production for three years have accumulated rich experience in flip-chip soldering technology and "package-free" R&D. Unlike other domestic LED companies that focus on vertical structure research and development of LED flashlights, Jinko uses gold-wire-free packaging technology. It is also the only domestic company that uses gold-wire-free packaging technology to develop LED flashlights.
Compared with the traditional packaging structure, the gold-wire-free packaging technology ensures high reliability of the product. It also has the advantages of low thermal resistance, ultra-thin packaging, small size and small color temperature difference. It can better leverage the advantages of LED. At the same time, it eliminates the need for packaging and wiring.
With this comparison, Jinko has embarked on the road of developing gold-wire-free packaged LED flash without hesitation. After a long period of painstaking research, Jinko finally reaped the rewards. It cracked the hard nut of LED flash and successfully developed a series of LED flash - E-Flash LED (gold-wire-free ceramic substrate packaged Flash LED light source). This series of products has the characteristics of compact structure, high luminous flux, high In order to quickly gain market recognition due to its advantages such as light efficiency, high current impact resistance, and good thermal conductivity, Jinko also invested a long time in solving application supporting solutions before putting it into the market. It is very easy for customers to use. Therefore, this star product, which Jinko has built this year, has received good response from customers once it was launched on the market.
