Recently, as LED filament lamps have gradually been recognized by the world market, the technology of filament lamps needs to be standardized, and the related patents for filament lamps also need to be recognized by manufacturers and sellers of filament lamps. On April 26th, Shenzhen Qingqing World, Gaogong LED held the first stop of the national patrol research activity of this year--a special seminar on filament lamps, and Professor Rui Chongguang, senior technical consultant of Ruidisheng, came to the scene to give a keynote speech. "At present, the key technologies of LED filament lamps include: LED filament design and manufacturing technology, filament lamp glass bulb sealing technology, stroboscopic constant current driving power supply technology, etc. These key design and manufacturing technologies are necessary for filament lamp manufacturers. Concern and have." Yan Chongguang pointed out. Yan Chongguang introduced that in 2010, Ruidisheng Optoelectronics took the lead in proposing a complete filament lamp solution in the industry and had its basic patent. The patent inventor is Ge Shichao, a retired researcher at Zhejiang University, and his team. After years of painstaking research, Mr. Ge successfully developed a light bar type LED bulb. The technology has obtained 2 national invention patents, 6 utility models and 13 appearances. At present, Ruidisheng has applied for a number of international patents, and the company has filed patents in 15 member countries of the European Union. The international patents that have been authorized so far are: the United States, Europe, Japan, South Korea, Canada, Australia, Denmark, Norway, Russia, Taiwan, Hong Kong, Macau, Singapore and other countries and regions. "The world needs 9 billion incandescent lamps every year. China produces about 4.44 billion incandescent lamps a year. If incandescent lamps are delisted, only the safety light source with similar performance and cost-effectiveness can be directly replaced." Point out. Yan Chongguang said that in 2015, the output of China's filament lamps will be about 150 million. In 2016, the output will increase by 3-5 times. The annual demand for safe light sources that can replace incandescent lamps in the world is still small. “But in this, the manufacturers of Chinese filament lamps need to strive for excellence and make better products to meet the needs of the world market. The filament lamps will inevitably become the wisdom of China in the future, and at the same time, the Chinese-made filament lamps will be sold to the global market. At that time, we must pay attention to relevant patents and cooperate with all parties. Only in this way can we win the world together!" Yan Zhongguang finally mentioned.
