According to the research results of National Semiconductor Lighting Engineering R&D and Industry Alliance, in 2013, the technological evolution process of LEDs was always accompanied by the outbreak of the market. The two complement each other and promote each other, but always focus on the theme of lower terminal cost. On the other hand, in the process of market expansion, the characteristics of high quality, environmental protection, health and other products are increasingly concerned by the market and society, and have become an issue that must be faced in the sustainable development of the LED industry. The industry's attention gradually shifted from lm/W to lm/$, and the price/performance and light quality became the core competitiveness of LED.
1. Cost reduction is still an important direction of technological breakthroughs In 2013, emerging technologies presented a situation of contending, among which COB packaging, eutectic EMC packaging, and gold-free wire packaging and other processes and technologies developed rapidly, becoming a breakthrough to continue to reduce costs and improve reliability. . In addition, in terms of product specifications, packaging companies have been aligning with high power in the past, and the proportion of medium power devices has increased due to the orientation of application requirements.
2. Beyond the lighting creative application to open up the new blue ocean in the fourth quarter, in the field of transcending lighting, the cross-border cooperation of optoelectronics and communication emerges endlessly. The innovative application of LED has appeared in aviation applications, positioning navigation, fashion creativity, living and home, etc. product. Wearable LEDs have become the highlight of Haute Couture clothing. LED simulation sunlight is the rehearsal of the No.3, and the 26th World University Winter Games uses LED light source torches to replace traditional fossil fuels. The successful application of indoor navigation and downhole positioning products based on LED optical communication. These industrial applications not only highlight the green, environmentally friendly, high-tech characteristics of LED, but also successfully expand the field of LED applications, or will become the new blue ocean of the future.
3, health, environmental protection, quality has become the focus of LED In 2013, the light pollution incident of outdoor advertising screens has been reported frequently, and cities such as Shenzhen and Guangzhou have introduced regulations to regulate and regulate. In the same period, the Blu-ray debate also aroused people's concern about the impact of LED lamps on human health. In terms of product quality, the recall of LED lighting fixtures frequently occurred, and the rate of unqualified products in the domestic market was high. Taking street lamps as an example, the Guangdong Provincial Bureau of Quality and Technical Supervision recently released the results of the special supervision and inspection of the quality of LED street lamps and light source controllers in Guangdong Province in 2013. The product failure rate still reached 25. While the market price of LED lamps is chaotic, the brand is not Significant, uneven quality has also become a constraint to the healthy development of the industry.
On the one hand, the standards, norms, testing and other services that regulate the market need to be matched; on the other hand, the industry also needs to strengthen self-discipline, do a good job of quality, establish a brand, and actively promote the benign development of the entire industry.
