-- Interview with Professor Cai Zuquan, a famous expert in electric light source. The reporter's Shanghai reporter Kong Jisong's background information Cai Zuquan, male, born in 1924 in Zhejiang Yuhang. Self-study, is a power expert from the workers. He entered Fudan University in 1952, was promoted to professor in 1978, and served as a master instructor in September 1981. He served as vice president of Fudan University, director of the Institute of Electric Light Sources of Fudan University, vice chairman of the Shanghai Association for Science and Technology, China Optical Society, China Light Industry Association. The first vice chairman, vice chairman of the China Lighting Society, is one of the pioneers of new electric light sources.
In the early 1960s, an electric light source research group led by Professor Cai carried out a series of research on new light sources, and made China's first high-pressure mercury lamp. By 1965, it had successfully developed iodine-tungsten lamps, long-arc xenon lamps, and super More than ten types of illumination sources and instrument light sources, such as high-pressure spherical xenon lamps, ultra-high pressure mercury lamps, hollow cathode lamps, hydrogen arc lamps, and isotope cesium (86) lamps, have greatly shortened the gap between China's electric light source research level and the international level. All kinds of novel and energy-saving light sources developed by him have won national and provincial-level creative invention awards and scientific and technological progress awards.
Cai Zuquan said: China needs to be strong, and the light source needs independent innovation!
On the afternoon of November 18, in the dormitory building of Fudan University, the reporter visited Professor Cai Zuquan, an electric light source expert at Fudan University. The scholar who has spent more than a year, is very enthusiastic, and he is very enthusiastic. He is 83 years old, and he is more and more rare in the coming year, but his vitality and spirit can not be trusted to believe that he is an "elder." Because the length of life is always limited, most people gradually return to calm and solitude at the end of their lives, but Professor Cai’s life has shown us a magnificent and horrifying scene: he still travels to the business and academic circles, and is busy Do technical guidance.

In 1951, Professor Cai was transferred from the Sino-French Pharmaceutical Factory to the X-ray Tube Laboratory of the Department of Physics, Shanghai Jiaotong University as a technician, assisting Zhou Tongqing and Professor Fang Junxin in the research and development of X-ray tubes. At that time, Shanghai Mayor Chen Yi attached great importance to intellectuals. In a symposium, Fang Junxin hoped to transfer Cai Zuquan from the Chinese medicine factory to the university. Soon at the end of the year, Cai Zuquan received a order and began to work in the X-ray tube laboratory of the Department of Physics of Jiaotong University. In 1952, the department was greatly adjusted. Cai Zuquan came to Fudan University with Professor Zhou Tongqing and Fang Junxin. He continued to work on the research and development of X-ray tubes, and was responsible for the welding technology of glass and metal copper rings, the glass sealing of X-ray tubes and the vacuum of glass. System maintenance.
In 1955, under the leadership of Professor Zhou Tongqing, I finally independently developed China's first X-ray tube to fill the gap in the domestic market technology. This was a great encouragement and inspiration to Professor Cai, who was only 30 years old at the time. Then, he saw that the main equipment of the vacuum system for developing X-ray tubes was imported. At that time, he decided to make more contributions to the country. In this technical field, he must step out of his own innovation, so he began to study vacuum. After obtaining and vacuum measuring equipment, after his research, in 1956, China's first vertical three-stage glass oil diffusion pump was successfully trial-produced, and the vacuum was 10 (-5) Pa, and then the McLaugh mercury vacuum hopper was developed, which can be measured. The vacuum degree of 10(-1)-10(-5)Pa has also been successful. These technologies and equipments have been successfully developed. They have made a foundation for the development and research and production of new electric light sources. After the 1960s, Cai Zuquan, who had not interrupted self-study, created China's first electric light source laboratory and began systematic research in this field. The first hydrogen lamp, the first high-pressure mercury lamp, the first iodine tungsten lamp, the first xenon lamp, and the first long-arc xenon lamp in the history of electric light source in China were born from his hands. It can be said that the Chinese electric light source industry has grown from scratch, from small to large, and reached a very high level today. Professor Cai Zuquan contributed a lot. He developed new light sources and new lights to make life change. Many middle-aged Shanghainese people still remember that in the 1960s, the 100KW long arc lamp on the Fudan campus and Shanghai People’s Square caused a huge sensation. It was also called “artificial sun†and was also called The Chinese "competition lamp", the inventor Cai Zuquan is also famous, with the "China Edison". This move has made Fudan University a leader in the field of electric light sources in the country.
In July 1966, Professor Cai attended the four continents international physics summer seminar on behalf of China. During the meeting, he was cordially received by Premier Zhou Enlai. Professor Cai said that this was the most memorable thing in his life! After the 1980s, Professor Cai’s research work entered a new period of development. On the one hand, Professor Cai actively engages in the writing of academic papers and the academic exchange of international light source and lighting. He has attended many international scientific and technological seminars to understand the latest development of electric light source development and timely transfer international professional information to domestic enterprises. To guide the research and development of light source lighting in China. At the same time, in response to the needs of modern economic construction, on the basis of the successful development of new light sources, more emphasis will be placed on secondary development-engineering development research, which will quickly transform scientific research results into productivity and achieve great economic and social benefits. Received the second prize of the National Science and Technology Commission.
Retire
After retiring in 1992, he still served as the honorary director of the Institute of Electric Light Sources of Fudan University. He always cares about the development of electric light source and talent cultivation, especially the promotion of energy-saving fluorescent lamps. He is often invited by well-known domestic enterprises to participate in corporate information. And the discussion of new product development, and he also continually took time and the teachers of the institute, the engineers of the enterprise to participate in the international electric light source academic seminar and foreign study about the famous lighting company, draw on the foreign electric light source innovation achievements and related development information, introduce To Chinese enterprises, to promote the development of China's electric light source, at the same time, he saw foreign companies doing electric light source, are large companies, have a very strong R & D team, have their own patented products, and at this time Professor Cai look In my eyes, I am anxious, he thinks, how to make China's lighting enterprises stronger and bigger, and more hope to win the international electric light source academic discussion in China, let more enterprise technicians and entrepreneurs attend the meeting, soon this After the proposal was put forward, it was supported by the China Lighting Industry Association, the China Lighting Society, the Fudan University Electric Light Source Research Institute and the electric light source enterprise. At the same time, we are enthusiastically supported by international light source and lighting experts. After six years of preparation, the 11th International Symposium on Electric Light Sources was officially held at Fudan University in China on May 21, 2007. This “Olympic Conferenceâ€, which has been hailed as a light source, has become an international electric light source. The largest number of academic conferences, the number of people reached 460, of which 180 were Chinese representatives. Through this international academic exchange, China's electric light source enterprises have a deep understanding of the development trend of international electric light sources, and have become more powerful for China's electric light source enterprises.
Heart-to-business relationship is a source of light. For our current Chinese lighting company, Professor Cai has placed deep expectations. He said: 1) The scale of light sources must be expanded. In foreign countries, light source companies are operating in large group companies. The light source enterprises are still in a growth period, and this international gap must be reduced. 2) Light source technology must be independent. In foreign countries, many core technologies are in the hands of some large group companies, but domestic enterprises are more It still relies on the research institutions of major universities or the imitation and imitation of foreign technology to innovate or introduce and absorb innovation. However, Chinese companies must have their own R&D team and core technologies to be strong and big. 3) The light source products must be rich. The three major light source giants such as GE, Osram and Philips have their own rich products on the product line. In contrast, our domestic enterprises are still too single in the product line. Invisible, this kind of competitiveness is inferior to these giants. "Of course, there are many problems in this process that need us to solve step by step. I believe that in the near future, our country will definitely have light source giants like GE, Osram and Philips...".
