On April 21, 2015, the 2015 G20-LED Summit CTO Conference (Hangzhou Station) was successfully held in Hangzhou, Zhejiang.
The topic of this CTO conference is “New Opportunities for Technology-Driven Supply Chainsâ€, which explores how to conduct technology research and development and innovation for the supply chain in the current industry environment. Participants are composed of technical leaders (CTO, technical director, technical chief) of G20-LED summit members. The conference continues to adhere to the purpose of the G20-LED Summit, creating a platform for technical exchanges and interactions for member companies, and is committed to promoting deep cooperation between technology and supply chain among member companies.
The meeting reached the following consensus:
1. Significance: This CTO meeting is a memorable meeting. Especially in this year, the LED industry development has reached a very critical turning point, especially for the optimization of the supply chain, which has reached the point of concern for the company's life and death. At the same time, I would like to thank the member companies, Sunshine Lighting, for their thoughtful work and support during the whole process of participating in the conference.
2, chip: LED penetration rate is gradually increasing, but the price is decreasing year by year. Therefore, whether it is a chip company or a packaging company, what everyone values ​​is how to reduce costs. The extension and the chip are linked together. Only by borrowing some of the technologies of the package, it is possible to produce a good quality and cost-effective LED through the cooperation of the entire supply chain in the upper, middle and lower reaches.
At present, the emergence of high current density chips provides favorable conditions for reducing production costs. At present, the key point of high current density chip products is how to achieve scale in terms of extension. Only brightness improvement, size reduction is the real cost reduction, which is now the pursuit of the entire chip manufacturer.
3. Substrate: At present, silicon substrate has no advantage, and the advantage of sapphire is more obvious. The advantage of a silicon substrate is that it can be 8 inches, but its lattice matching is poor and the process is more complicated than sapphire. The biggest problem in the industry of GaN substrates is the cost. If the cost problem is solved, the market potential in the future is very large.
4. Packaging trends: The evolution of packaged products will move toward chip-level packaging trends. The first is the CSP package, and then the flip-chip COB, mainly reflected in the future consumption of these two products will be very large, especially in commercial lighting. At the same time, the 2835 product has a great advantage, including the application of the whole field, excellent cost performance and strong compatibility. Since the 2835 is mainly used in the small and medium power field, the isolated power supply will be used more, and the PCT is expected to form a scale.
5, CSP package: Now everyone is moving towards small-sized CSP devices, CSP package will greatly reduce the cost of packaging in materials. The CSP chip with flip-chip structure will bring about a significant increase in packaging efficiency for the packaging company, and the product concentration will be greatly improved. The color consistency and color uniformity will be very large. Improvement.
6, power: power supply development trend has three main points. The first is standardization. The early power supplies are matched point-to-point. In the future, they will be point-to-point matching. Secondly, digital power supply can make the volume smaller, the response speed is faster, and the cost performance is higher. Once again, it is intelligent, and now intelligent lighting has begun to enter more applications.
7. Driver IC: The idea of ​​“de-energizing†is popular in the industry. In the realization of optics, thermals, electricity, and collection drive, light source module, phosphor, heat management, to achieve miniaturization of power supply, this pair The technical requirements of the enterprise are relatively high. At the same time, the ultimate integration of intelligence, so this is also the direction of the power companies' efforts.
Consumers have high requirements for intelligence. Smart cities are not just street lights, but also indoor lighting, which provides a good direction for the development of technologies such as driving, monitoring and sensing. All of these will undoubtedly bring great challenges to the technical level of the company, and it is expected to attract a new round of industry reshuffle.
8. Equipment: At present, the three major problems of lack of human resources, product quality and factory performance have always plagued the healthy development of enterprises in the industry. Therefore, around the mechanized, intelligent, and efficient management of the three major pieces of intelligent equipment, has become the current research and development direction of equipment companies. With the factory intelligent upgrade, to improve product quality, order delivery, inventory reduction, management optimization, and corporate image, to help customers improve the core competitiveness of the entire plant.
9. Indoor lighting: At present, the intelligent lighting on the market can only be the simple control of light and color. The best is to use the mobile APP control. This level can be done by anyone. There is no need to develop at all. The current intelligent lighting is far from true wisdom. Lighting is too early. Intelligent lighting can only reach the customer's consumer demand point in order to attract customers.
From a market perspective, technology needs to serve sales and lead sales. Consumers are concerned about the angle of illumination, color rendering index and other factors, indicating that the light efficiency is above 90, followed by R9. The company's product portfolio needs to be able to meet the different needs of customers, and can be combined at will, convenient and fast. Only when the product keeps pace with the times can we form a strong competitive edge.
10, outdoor lighting: to achieve customer core needs, is the ultimate goal of the enterprise. The product is simplified and rationalized to meet the needs of direct users, the demand for lighting life, and the development of smart cities, so that the heat dissipation of products is close to the needs of users, and it is an ideal state for all street lamp management departments.
The two core requirements of outdoor lighting are nothing more than reliability and ease of maintenance. The maintenance of ordinary outdoor lighting requires a lot of cost. Good lights are easy to repair and disassembled by hand. This is an important direction of R&D. Modularization provides favorable conditions for solving these two demands. At the same time, the emergence of intelligence has become the focus of outdoor lighting appreciation.
Therefore, the research and development direction of outdoor lighting mainly has four points: 1. Deeply digging customers' needs; 2. Optimizing costs, 3. Avoiding the continuous deterioration of price wars; 4. Developing products with independent concepts, based on the understanding of the market, to be yourself Recognized things.
