On May 25th, the 9th China International Performing Arts Equipment and Technology Forum hosted by China Performing Arts Equipment Technology Association and China Technology Market Management Center, organized by Beijing Performing Arts Technology Magazine and China Performing Arts Equipment Technology Association Performance Stadium Professional Committee The Beijing Royal Hotel held more than 200 experts from more than 10 countries, including the United States, Germany, and the Czech Republic, as well as experts, scholars, and application technicians from government agencies, research institutes, performance venues, and performance groups from across the country. Forum. The forum was chaired by Lao Weijie, deputy director of the China Performing Arts Equipment Technology Association. The theme of this forum selected green, low-carbon topics that are of common concern to all governments at the moment: “Green lighting technology and stage lighting”.
Wang Feng, Deputy Director of the Department of Culture and Technology of the Ministry of Culture, on behalf of the Ministry of Culture, congratulated the opening of the forum and introduced the current state’s policy of attaching importance to cultural and scientific innovation. He said that the cultural innovation project, the restructuring of cultural and scientific technology, the formulation of a plan for the promotion of cultural and scientific innovation, and the establishment of a cultural innovation and development fund in the next step are all concrete examples of national support for this area. The Ministry of Culture and Technology recently organized a related meeting. The participating experts showed considerable enthusiasm for the development and demonstration application of green light stage functional lamps. Zhu Xincun, Chairman of the China Performing Arts Equipment Technology Association, and Huang Yajuan, the General Manager of the Yazhou District of the distinguished guest of the National Research and Exhibition Group, addressed the organizers.
This forum adopted the keynote speech and invited seven industry experts from home and abroad to share in-depth themes from different aspects.
Shanghai Academy of Drama Professor Liu Dean, entitled “Thinking about Green Lighting for Stage Lighting”, released his joint research results with Jin Changlie, Chen Guoyi, and Yao Hanchun. He raised the standard issue of green lighting for stage lighting fixtures - high performance, energy saving, environmental protection, safety and perfect stage performance. He believes that high-efficiency energy-saving is to reduce electric energy consumption, and at the same time reduce power plant pollution to the environment. Environmental protection should be reflected in the entire process of production, use, and disposal of lamps and lanterns. The problem of pollution-free, recyclable, and recycled use of light sources and lamps after they are scrapped is new area. He stressed that long life is an important part of energy conservation and environmental protection. The optical life of the LED does not replace the lifetime of the product. The lifetime of the electrical
Accessories and the optical device will directly affect the life of the LED product.
"The application and prospect of LED lamps in film and television studios" is the development manager of Germany Allai Television Equipment Co., Ltd. and Marcus Ludwig brings professional topics to the forum. He combined the example of LED lamps in the studio application, put forward the advantages and problems faced by LED in TV studio and feature film shooting. He believes that under the current technical conditions, LED lamps cannot be replaced. All light types, but its use will become more and more extensive.
The speech of Mike Wood, the chairman of PLASA Professional Lighting and Sound Association, was entitled “The Application of Solid-State Light Sources in the Performing Arts Lighting Industry”. With his own long-term optical experiments and practical experience, from a technical point of view, he compared the LED light source and the plasma light source. He believes that, in practical use, the performance and characteristics of the light fixture should be fully understood, and the combination of lengths and shorts should be applied.
The leader of the PLASA Professional Lighting and Sound Association Management Committee, Mr. Steve Terry from the United States focused his speech on the professional technical field - the performance characteristics of LED stage lighting. His speech started with the comparison of the color gamut characteristics of incandescent, HID, and LED fixtures, and deepened the problems of thermal-induced light decay, color accuracy, and color control solutions for multi-color LED fixtures. The discussion. He pointed out that the LED luminaires must be correctly selected according to the needs of different users for a particular application.
Joseph Foreher, CEO of the Czech company Robe Lighting, addressed the theme of plasma technology in the development of computer lights. He combined his company's development of plasma lamps in 2009 and explained the application of plasma light sources in moving head lighting equipment. . Tom Morris, the manager of Ocean Optics Co., Ltd. of the United States, combined with a large number of actual cases of LEP products around the world, from the manufacturer's point of view, described the actual application of plasma lamps.
Nguyen Jun, Deputy Secretary-General of National Semiconductor Lighting Engineering R&D and Industry Alliance pointed out from the macro perspective of the development strategy of China's semiconductor lighting industry. From the point of view of development, the industrial chain of this industry is still shortening, the integration technology is continuously applied, and the current LED industry development bottleneck It mainly focuses on the competition of talents caused by the small scale of the industry and competition in the industry; and the localization of core technologies is the key issue in reducing production costs.
