[High-tech LED reporter Liu Pingping] On January 1 this year, the best-selling 40-watt and 60-watt incandescent lamps in the US market stopped selling. At the same time, in Asia, South Korea, Thailand, and the Philippines have also taken measures to promote the use of energy-saving light bulbs instead of incandescent light bulbs. As countries begin to completely ban incandescent lamps, the replacement of light sources will be fully opened in 2014, and LED lamps are expected to gradually occupy the lighting market.
Whether the LED light source can fully enter the lighting field, the cost of the light source is the most critical. From the current point of view, there is still a considerable gap between the cost difference of different LED products and the traditional products, and the main technical indicators need to be further improved. The continuous introduction of new structures, new materials, new technologies and new processes has undoubtedly brought new pressure on LED costs.
Faced with the survival challenge brought by price competition, it is the top priority of LED industry chain to find ways to control the cost of light source.
The industry believes that reducing costs can start with large-scale production and improved yield. From this level, the higher the scale of revenue, the more obvious the advantages, such as Sanan Optoelectronics, Hongli Optoelectronics, Guoxing Optoelectronics, etc.
The second is to reduce costs through technological innovation.
Speaking of this, I have to mention the "no package" chip that has recently triggered industry hot discussions. The reporter learned that Xiamen Tongshida Lighting Co., Ltd. has announced that it will use the "package-free" POD light source device of TSMC solid-state lighting to develop a new generation of lighting products.
Since no packaging technology can significantly reduce costs, there are many Taiwanese and foreign companies that have developed and produced them, including Taiwan LED chip factory, Jingdian, Yuyuan, one-stop factory, TSMC solid-state lighting, Ronda, and international company Toshiba. , CREE, PhilipsLumileds, etc.
Again, it includes package cost and lamp cost. This requires the joint efforts of midstream packaging companies and downstream application companies.
In addition, what are the space for LED light source cost reduction? How will it be implemented? On February 23, 2014, the New Year Forum hosted by Gaogong LED - 2014 LED lighting e-commerce and supply chain integration summit will be held soon, the CEOs of major companies will gather at Shangri-La Hotel, Guangzhou Pazhou, in the CEO round-table dialogue, will be The topic of “decreasing the cost of LED light sources in the next three years” is discussed together.
