This project belongs to the technical field of special new light source lighting appliances, involving the technical field of ultra-high temperature 3600℃ laser welding and the field of ultra-high temperature fine technical equipment for intelligent control robots. In the "Twelfth Five-Year Plan", with the advancement of public cultural service system construction projects such as national radio and television village access and rural film screening projects, projection lamp lighting technology has been widely used in industries. Ultra-high voltage electrode assembly equipment is a special new light source. The key main equipment of the projection lamp. At present, projection lamp equipment relies on imports, and its technology is monopolized by a few developed countries in Europe and the United States. To this end, we have formed a domestic projector alliance with dozens of companies, conducted industry-university-research cooperation with Shanghai Fudan University, and made breakthroughs in key components such as projection lamp electrodes, ultra-high voltage, and ultra-high temperature, and formed a number of scientific and technological achievements. The breakthrough in key technologies of ultra-high-pressure projection lamp click composition marks that China has entered the world's advanced ranks in the manufacturing of special light sources.
For the first time in China, an ultra-high temperature electrode with a working temperature of 3000 ° C has been successfully developed, a new material for burning hydrogen for vacuum treatment has been independently developed, a laser for removing impurities on the electrode surface has been designed to change the body structure, and a melting equipment laser with a temperature of 3600 ° C has been developed. The tungsten material is melted into a bullet-shaped electrode, which enables the melting of tungsten material as large as grains of rice into a key accessory for a bullet-shaped electrode with exactly the exact size requirements. The breakthrough in ultra-high temperature 3600℃ laser technology has had a huge impact on the industry, making Yar Light Source Company the world's leader in the point light source parts industry. Philips has withdrawn from the light source parts industry, closed its factories in the Netherlands, and purchased all Yar products; foreign light source companies such as GE of the United States, Osram of Germany and Panasonic of Japan purchase Yar products.
For the first time, the world has successfully developed 3600 ° C laser melting technology and ultra-high temperature laser welding process technology, and invented the micro-technology equipment technology of intelligent control robots to melt and weld hair-thick materials in an ultra-high temperature environment of 3600 ° C. It solves the technical bottleneck of traditional melting and welding, improves the quality of products, fills domestic gaps, and provides technical support for aerospace manufacturing, ultra-large-scale integrated circuits and other fields.
For the first time, China has successfully developed a microspace electrode assembly manufacturing process and equipment, breaking through the technical barriers of working electrode distance of about 1mm and working pressure of 200bar (atmospheric pressure), and achieving cleanliness during the manufacturing of ultra-high performance projection lamp electrodes., stability and other technical requirements have formed a series of product technologies with independent intellectual property rights, improved the core technology of enterprise lighting source technology, and promoted the development of product technology in the projector industry.
This project has been authorized for 1 invention, 2 utility models, 3 inventions, 1 technical standard, 1 specification, and 3 papers published. After scientific and technological novelty search consultation and expert acceptance, the project has reached the international advanced level in the process technology of electrode assemblies of special new light sources and ultra-high voltage projection lamps. This project has become a major product supplier to GE in the United States, Philips in the Netherlands, Panasonic in Japan, and Jiangsu Senlai Optoelectronics Technology Co., Ltd. Over the past three years, the project has a cumulative output value of 340 million yuan, a profit of 52 million yuan, an additional tax revenue of 18 million yuan, and a foreign exchange of 7.6 million US dollars. The scientific and technological achievements of this project have contributed to the development of the domestic projector industry.
