How to circumvent the defects of foreign brands' technology routes and build their own core technology system-Li Yi, who has been troubled by this problem for a long time, found inspiration from the development process of the LED lighting industry, and finally set the tone to the fluorescent color wheel + Laser ideas. However, the road to innovation is not so easy to imagine-the use of fluorescence means that the problem of burning high-energy lasers with fluorescent materials must be solved. After repeated attempts and verification, this technical problem was finally overcome and China's own laser pointer projection technology was created. This unique technical route has no speckle, high brightness (55000lm fluorescent laser projector has been developed at present), long life (30,000 hours), slow light decay (maintain 70% of the initial brightness at the end of life), and low power consumption (Enhancing energy consumption by about 40% compared with bulb machines) and other inherent advantages, while achieving technological breakthroughs, it also avoided the shortcomings of the remaining laser projection technology to the greatest extent, and for the first time established a "new height in China" in the field of projection technology.
However, the market application of new technologies with laser pointers is just the beginning. For the stock market of projection equipment completely covered by xenon light sources, the inherent usage habits of theater operators and the relatively high cost of laser machines have become the two "stoppers" that hinder the landing of laser projection technology. This problem has become a foreign technology brand. The common challenge faced by the RGB laser camp and Dr. Li Yi's ALPD camp means that whoever can take the lead in solving application problems can take the lead in the laser projection technology market, and will become the stick of the industry's right to speak in the future. By.
In this regard, Zhongying Guangfeng has also made bold innovations in its business model: based on its own advantages in the field of technology research and development, the use of light sources has replaced the application, simplifying the upgrade process. At the same time, the company has introduced a rental model that counts by the hour. The theater operator only needs to pay the rent according to the length of use, thereby avoiding the huge investment in the purchase of the overall laser projection equipment-optimized movie projection quality + reasonable use costs, giving the ALPD fluorescence laser projection technology a sharp sword After starting commercial use, in just two years, it has achieved 9,000 installations in the domestic market alone-this time, Chinese brands finally ran ahead.
In ten years, from being initially questioned by the industry to the launch of ALPD 4.0, the product has achieved full coverage of 10,000 to the current maximum of 55,000 lumens in the field of fluorescent lasers; from the initial question by investors, to the present With 9,000 sets of domestic market installations, ALPD fluorescent laser projection technology has caused a series of chain reactions, which not only drove the film development towards high dynamics, high frame rate, wide color gamut, etc., but also promoted film post-production. Role-The road of R & D and promotion of Dr. Li Yi and China Film Guangfeng is also the epitome and hope of the development of Chinese film projection technology.
In a deeper sense, the laser pointer projection technology has won more than 1,000 patents worldwide, and a stone city soup pond surrounding a fluorescent pink wheel + laser has been firmly erected. One sword in ten years, in the field of film screening in the high-tech test field, Chinese brands have leapt from imitating and following to leading the world with independent patents. This is probably the birth of a "Chinese core" with a very high gold content.
