At 8 p.m. on February 4, the world-renowned Beijing 2022 Winter Olympics officially kicked off at the "Bird's Nest" National Stadium.
At the same time, thousands of miles away from the opening ceremony of the Winter Olympic Games in Shenzhen Branch, Shenzhen Guangfeng Technology, the world's leading laser display manufacturer, used this laser beam to write the four big characters of "One in the World" in the cloud at a height of thousands of meters, and played the "five rings" logo in the cloud, using original technology and creative images to cheer and cheer for the Beijing Winter Olympics.
Why can Guangfeng Technology "write" in the cloud at a height of 1,000 meters
It is reported that this is Guangfeng fueling the Winter Olympics, and it is the world's first laser imaging technology to "write" in the cloud at a height of 1,000 meters. For the final presentation of such a creative plan, the relevant personnel of Guangfeng Technology said that the implementation of the image scheme of "cloud book" of thousands of meters can be said to be short cycle time, heavy task, and great social significance.
The implementation of this plan is particularly complex in the process, and the impact of factors such as weather and complex scenes on the site must be taken into account. Behind this, it is especially necessary to achieve perfect "balance" between key technologies such as fusion technology, ultra-high brightness, speckle suppression technology, and uniform illumination. Fortunately, Guangfeng Technology relies on the original hard-core ALPD laser technology and strong technical service capabilities to ensure that this solution is finally perfectly presented.
It is understood that ALPD laser display technology has the characteristics of high imaging efficiency and stable optical performance, compared with other light sources, the color is more pure, the brightness is more uniform, the color range is wider, the light source control is more accurate, and it is not disturbed to break through the obstacles, which can perfectly present the reality of the world.
In this case, five dazzling laser pillars of light rushed into the clouds, and finally wrote out the four big characters of "One in the World" at a height of thousands of meters, and typed "five rings" in the cloud, which is a good demonstration of the ALPD laser display technology independently developed by Guangfeng Technology, which has the characteristics of high brightness, high image quality and high reliability.
Zhang Feng, general manager of Guangfeng Science and Technology Engineering Division, said that there is no limit to the pursuit of brightness in laser display technology. Laser light source is not only an efficient, high-brightness, high-reliability light source, but also has a "linear feature", using the method of fiber coupling, theoretically can obtain "infinite brightness" light source system.
This time, the demand for "cloud book" in the Shenzhen branch venue synchronous superimposed ultra-long-distance projection technology, breaking through the distance limit of 500 meters of conventional projection technology, to achieve high-altitude long-distance imaging up to 3,000 meters, especially relying on Guangfeng Technology in the stand-alone laser equipment up to 100,000 lumens ultra-high brightness, but also because of this high brightness to ensure that thousands of meters of clouds show the naked eye visible to the naked eye.
In addition, according to the relevant personnel of Guangfeng Technology, the display of the "cloud book" program of thousands of meters, in addition to the laser display equipment to 100,000 lumens ultra-high brightness will inevitably require many technical upgrades. For example, although the laser display "as long as the volume allows, the brightness is not a problem", but the key to the problem is how to ensure the brightness at the same time, but also to make the volume space become "slim", which is a relatively complex system problem, testing the R & D personnel on thermal management, system management and internal architecture and other aspects of the comprehensive balance ability. In this regard, the laser is required to greatly improve the efficiency of electro-optical conversion, reduce heat loss, combine the heat dissipation technology of 3DVC, so that the volume of the device is doubled, and the traditional ultra-high brightness display device heat is large, and many technical problems such as large heat dissipation devices are required.
In particular, the brightness reaches above tens of thousands of lumens, and each time the first lumen is pulled up, it is a great test of the manufacturer's ability to grasp the "performance balance" of heat dissipation and various internal optical indicators. It is conceivable that the equipment this time can reach 100,000 lumens of the optical machine placed in a relatively small volume space, which fully demonstrates that Guangfeng Technology has achieved "perfect balance and optimization" in various core technical links such as laser light source, fixed optical path and light effect management technology, and heat dissipation as the core support system, which is behind The comprehensive embodiment of Guangfeng Technology's strong original innovation strength and solid research and development capabilities in laser display technology.
Through a beam of light, what does Guangfeng Technology "illuminate"?
According to Lotu technology data, in the first half of 2021 last year, the Chinese mainland laser projection market shipments were 234,000 units, and it is expected to exceed 600,000 units throughout the year, which is becoming the most "dazzling" display technology solution in the entire large display sector.
However, compared with other display technologies, the overall total scale of laser display is still in the "initial stage". In the future, this display category also needs to "walk in tandem" in terms of brand engagement, technical propulsion, and product segmentation scene breakthroughs.
Especially from the current development trend, the laser display should maintain the upper volume or further in the market side. The key pusher is to play the "application" card well and explore the special value of lasers, such as high brightness, long life, low maintenance, high reliability and other advantages.
The great advantage of laser display is that it is not only an ideal solution for giant screen display, but also the characteristics of "the picture can be deformed at will", which will bring more diversified application innovation space to creative images. For example, complex commercial application scenarios such as floor display, ceiling display, whole wall display, arc display, spherical display, and photo-carved projection display have a high degree of compatibility with the advantages of laser display products.
This time, Guangfeng Technology used 100,000 lumens of high-brightness equipment to "write a book" in thousands of meters of clouds, imaged with light, and lit up the night sky! This not only interprets the illumination height of the laser display, but also highlights the width and thickness of the laser display application, which is another "demonstration benchmark" of the innovative application of laser display technology, which will bring more "enlightenment" to the industry application, which can be said to be an innovation of application breakthrough, and once again broadens the application scope of projection vision.
In this regard, an industry expert said that the application width and height of laser display technology are exerted, giving it more application scenarios and vitality, and building a laser display full ecological innovation and collaborative innovation, which may be the most important proposition for the sustainable development of laser display manufacturers. Perhaps the scale of quantity has never been the connotation of laser display: higher, faster, stronger Olympic spirit is the most compatible with laser display, laser display to do is to achieve the height of experience that other technologies can not reach, and then achieve their own unique market.
Through a beam of light, he plays the role of a subversive in the world of light and shadow. This is the original intention of Li Yi, the founder of Guangfeng Technology. It can be said that Guangfeng Technology's use of laser light to "write a book" in the thousand-meter cloud is the first step in realizing Li Yi's grand vision.
Postscript: In 2022, Guangfeng Technology opened the kilometer cloud through the laser display to "write a book" for the Beijing Winter Olympics, which can be described as "setting the future height of laser display again". At the moment when laser display applications break through the skyline, that is, the starting point for the laser display market to further jump to new limits. The peak of light laser shows that the target "star sea" will climb the peak again from this moment.
