Hongdae Phosphors: Carrying out anti-counterfeiting work to the end
Text / "High-tech LED" reporter Tang Guirong
"We have been using Hongdae phosphors for more than ten years." In the white light package exchange meeting held by Hongda Trading Co., Ltd. (hereinafter referred to as "Hongdae") in May, the packaging manufacturers of the conference told the senior engineers. LED reporter.
In the case of domestic phosphors almost blank, Hongdae entered the Chinese market, cultivated for dozens of years, and occupied 50% of China's phosphor market share. However, Hongdae has always maintained a low-key attitude.
The brand's trust and loyalty may be a double-edged sword. On the one hand, Hongdae's phosphors are on the mainland, but on the other hand, they have attracted many counterfeit and shoddy products. In the face of the Hong Kong counterfeit products that Hong Kong has repeatedly banned, Zheng Weiyuan, general manager of Hongda University, frowned. "Fake and shoddy products have made Hongda's customers suffer."
However, Zheng Weiyuan did not show much concern. "We have been doing anti-counterfeiting work, and constantly improve the anti-counterfeiting certification website and launch anti-counterfeiting trademarks. In the future, we will have more exchanges in the mainland."

"This is a freely competitive economic era, and the market needs reasonable competition," Zheng said. "We think that Intel is a respectable competitor because he has never used any counterfeit goods."
Hongdae has maintained a low-key attitude in the Chinese market. However, in response to repeated counterfeit and shoddy products, Hongdae vowed at the May seminar that Hongdae phosphors were all produced in Japan, and Hongdae did not do OEM work in China or Taiwan.
At the same time, Hongdae pioneered the anti-counterfeiting trademark in the LED packaging industry and established an anti-counterfeiting certification website. “In the past, we only released product information for certain specific manufacturers. Now all product information is published on the website, and the product trademark is inquired on the anti-counterfeiting certification website.â€
In recent years, China's LED lighting industry has developed very rapidly. Although it has suffered from counterfeit and frustration, Hongdae phosphors still maintain a 50% market share, and the year-on-year growth rate has risen rapidly.
“Hongdae cherishes this 50% market share and has always attached great importance to the Chinese mainland market.†For this reason, Zheng Weiyuan came to the mainland for the first time in more than ten years, and exchanged white light packaging technology and experience with packaging engineers.
Test 3000 hours
In 1962, Hongdae was established. "At the beginning, we also always have problems that we are currently studying, such as the ratio of phosphors, wavelengths, pigments, etc." Zheng Chengyuan said, "However, engineers are most important to know how to study, How to achieve the best stability."
Currently, phosphor manufacturers generally test for 3,000 hours, but half-light decay usually occurs after testing.
“It’s easy to measure 1000 hours of phosphors, but the lighting should be lit at least 3000-5000 hours. When Hongda tests the phosphors, the brightness is also from the original 100% from 1000 hours to 3000 hours. 80%", although the results of this test did not reach the ideal value, but these data can be used to study the series of factors affecting brightness.
It is understood that the brightness of phosphors that have been tested for 3,000 hours on the market is generally maintained at around 60%. After years of testing, Hongdae has achieved a brightness of 80% after 3000 hours.
"Testing 3000 hours, there is another meaning. Testing 3000 hours is not simply to see the brightness of the phosphor. You can also test other related accessories, because in the lighting and backlight applications, a thousand of data is really deceiving yourself. Three thousand does not necessarily have good data, and it does not necessarily return to the data you want, but that is the data that can help you improve next. This is the point."
Maintain product stability <br> This year, LED lighting showed a downward trend in prices, but the price of phosphors rose. Li Dongping, general manager of Hongda phosphor agent Dongguan Hongcheng, said that although the country's control of rare earth resources is a direct factor leading to the rise in phosphor prices, the maturity of the LED industry needs to be integrated over time.
At present, the price wars on the market are one after another. Zheng Weiyuan said that Hongdae did not participate in the price war, because manufacturers of price wars often ignore product quality problems.
Zheng Weiyuan also repeatedly stressed that although the phosphor comes from Japan, Hongdae does not distinguish between Taiwanese phosphors and continental phosphors.
Regarding the quality of the products, Hongda phosphor agent Lin Lizhen said that Lu Yao knows horsepower, the key to phosphors depends on stability.
“The target map is an important factor in measuring the concentration. It is also an important difference between Hongdae and some domestic manufacturers. At present, no one has a target concentration of 100%, which can only be 100% closeâ€, Zheng Yuanfeng Said. Because the highest brightness is not necessarily the best uniformity and stability, the highest concentration.
The position of the engineer is to study the brightest phosphors, and the buyer's position is to get the most reasonable price.
"The inheritance of experience has also made certain Japanese chemical plants in Japan have an advantage in product uniformity and stability." It is understood that the current production of phosphors by Hongda can also achieve high concentration.
Enrich product lines and improve color rendering
Where is the myth behind the phosphor? The process and technology of phosphors have attracted the curiosity of many industry peers. "In fact, phosphors are not so simple, and there are no myths. The types of phosphors are very complex, requiring not only technology but also experience."
Many packaging customers believe that Hongdae's phosphor product line is relatively simple. Zheng Weiyuan said that Hongdae's product line is actually very rich. 00902 and 432 are the mother systems of phosphors, and almost all of them are derived from this.
New products derived from 00902 and 432 are emerging one after another. Will old products such as 432 and 00902 be replaced? To this end, Zheng Weiyuan said that while packaging manufacturers identified 432 and 00902 as old products, they also recognized that they are stable products, so despite the continuous improvement of R&D and innovation, 432 and 00902 have launched different series from sales to the present. But the product has never been removed.
For the development and trend of phosphors in the future, Zheng Weiyuan said that phosphors have been roughly shaped in terms of types and types. The next topic is how to improve color rendering, but because some phosphors have been restrained and cannot be solved, therefore, The high color rendering of future phosphors will improve in green and red-green.
For how to improve the first color rendering, Zheng Weiyuan revealed that he first started with YG Green Light, and then proceeded from the nitride red. It is understood that due to the existence of blind spots in silicate, Hongdae has always maintained a conservative attitude towards silicates, but there will be a major breakthrough in silicates, with customers offering a variety of options.
“Nano-phosphor is a direction, but the time has not yet arrived because the cost of using nano is too high.â€
