The ninth big-screen exhibition, although there are not many exhibitors, and Beijing-based enterprises are the most important, but the project of "LED light source", which has been deeply valued by the industry, still ushered in two exhibitors.
At the conference, Qiu showed a back projection LED light source to the industry audience. The product label indicates that its original factory is Japan. This is also a rare public display of Japanese background LED light source back projection products. The product uses red, green and blue ternary primary color LED light source. The order of arrangement is not a common "mouth" type, and the three-color source is arranged in three sides; instead, the "L" type, green and blue are arranged on the same side. The unique design of this product has attracted the attention of many viewers.
On the other side of the show, Lanbo showed a 2*5 LED light source splicing wall. Although from the field effect, LED light source products compared to another product of Lanbo, the dual-lamp DLP rear projection is strong, and still does not dominate the brightness, but its color performance is significantly better than the traditional light source products. According to Lanbo, the company is one of the few companies in China that can practically use LED light source TV wall products. Although there is still a certain way to go in terms of brightness, from the perspective of trend, the future of the splicing wall must belong to the LED light source.
As an energy-efficient cold light source technology, LED light source products are increasingly penetrating many aspects of production and life. Not only is the projection light source product, the technology has the opportunity to show great glory. In the ordinary lighting field, the LED light source has already revealed the king's breath.
Applied to projection display technology, LED light source first solves the life problems of traditional mercury lamps, environmental pollution problems, high energy consumption problems, and also helps to improve the display quality of products. From the perspective of long-term technological evolution, the cost of LED light sources will also be lower than that of traditional mercury lamps. Therefore, the industry also has this saying, "In addition to the technically climbing stage, LED light sources are everywhere."
In this year's big-screen exhibition, under the background of few DLP rear-projection and positive investment products, there are still two products grandly unveiled, which fully reflects the market and the industry's consensus on the bright future of LED light source.
However, among the factors learned in the projection era, there are also opinions that are not conducive to the popularity of LED light sources. For example, some insiders are also worried that once the LED light source is popular, the profits of related companies selling "light bulbs" will disappear. This will significantly change the current value chain of DLP projection and large-screen industry, and even have a reconfigive impact on the entire industry, and it will not rule out a certain "unemployment" phenomenon.
There is also a lot of worry about the slow increase in brightness of LED light sources and the fact that the cost is not as good as expected. It is understood that most of the companies in the industry are still in the "testing" mentality. It is very good for enterprises, or customers to use LED light source as the main application demand. Most enterprises in the industry have a "small taste" and "testing water" attitude, and the lack of upstream industrial chain of the domestic LED industry, high-end and upstream products rely heavily on import factors, is considered to be a certain degree of slowdown LED light source products The pace of market maturity.
According to the analysis, in the next two or three years, the LED light source projection display technology will be in the stage of “diving†and will not become the main profit point and main product of the enterprise. The market volatility and low-key of the industry climbing period will be the LED light source projection during this period, especially the main trend and law of the rear-projection wall industry.
PUR cable is a type of cable that is specifically designed to withstand exposure to oil and other petroleum-based substances. The sheath of the cable is made from a material called polyurethane (PUR), which is known for its resistance to oil, chemicals, and abrasion.
The oil resistance of this type of cable makes it ideal for use in industrial environments where there is a high risk of exposure to oil or other similar substances. It can be used in applications such as oil refineries, chemical plants, and automotive manufacturing facilities.
The PUR sheath also provides excellent mechanical protection, making the cable highly durable and resistant to damage from impacts or abrasion. This makes it suitable for use in harsh environments where the cable may be subjected to heavy use or rough handling.
In addition to its oil resistance, PUR sheathed cable often has other desirable properties such as flame resistance, UV resistance, and flexibility. These properties make it a versatile choice for a wide range of applications where durability and reliability are important.
Overall, PUR cable is a reliable and durable option for applications that require protection against oil and other petroleum-based substances. Its ability to withstand harsh environments and resist damage makes it a popular choice in various industries.
