Controversy renewed LED filament lamp way clear road?

LED filament lamp controversy renewed.

Recently, general manager of Samsung LED Chinese Tang Guoqing to attend a meeting: mentioned in the LED lamp in the end is a historical retrogression, and the future development direction of LED bulb, now the industry Public opinions are divergent. this phenomenon at least, LED is a filament lamp is obviously insufficient, suggest that we don't need a few more things, my heart why.

The Hongkong DesignLed technical director Xu Zhengrong's opposition is more clear. He said: LED filament is no security at all, simply can not pass the security regulations, not to mention the European and American markets, is the third world markets are afraid to push. Coupled with its ultra low yield, painful process, I do not think it is a future direction of development. Also, I get a clear message from PHILPS and Chinese international purchasing department is that PHILPS will not buy LED filament lamp, the PHILPS LED market to China outsourcing orders that determine the basic filament lamp is fake. "

Safety rules can not pass?

However, as Xu Zhengrong said, LED filament lamp no security at all, the third world markets are afraid to push it?

BYD lighting LED application development center manager and plant manager Tang Jun said, LED filament lamp we have in mind, I think life is always a problem, as the security rules are not a big problem. "

"I think those manufacturers LED filament lamp manufacturers still have a way to solve the safety problem. "Fan Zhencan also said President ashineon.

"We are about 80% of orders from Europe, LED filament lamp is a partial aristocratic style of products, this product in Europe and the United States on the Japanese market recognition is much higher than the domestic market. Wang Peng, deputy general manager of the lion lion in an interview with China LED network editor said that the lion LED filament lamp production capacity of 50-100 million / month, the current production capacity can not meet the order requirements, is expanding the scale of production capacity.

The successful transition from the traditional incandescent cut LED filament lamp Ayura Terua, the current production capacity has more than 2 million per month, and due to the demand for orders in the state of continuous expansion. Recently developed two new markets, the United States and Japan, are very good. In an interview with China LED network editor interview, chairman Ayura Terua Dai Jian revealed.

Wang Peng also said that the lion lion photoelectric part of the LED filament lamp products shipped to the United States and japan. "But it's still the largest in europe. Dai Jian and Wang Pengjun said.

As for the relevant safety regulations certification, Wang Peng believes that the lion lion photoelectric LED filament lamp has now passed the European CE, the United States and Japan ETL related certification. Dai Jian also said that in addition to the required certification through the target market, the recent Yapu'er got American UL certificate.

Gao Jiwei, director of the Department of optical technology, said, export, then the relevant safety certification is necessary. According to Gao Jiwei revealed that the current section of the LED filament lamp production capacity of 2 million / month, capacity utilization of about 50%, both domestic and foreign markets have sales, foreign markets are mainly concentrated in Europe and russia. "There's a part of South America and the middle east. "

Times pass certification testing center marketing manager Li Yanchan told the China LED network editor, there are related businesses LED filament lamp project in times to do the relevant certification, and has been adopted.

Yield low?

As for the yield rate of LED filament lamp, the company involved in the LED filament lamp manufacturers said that the need to further improve. Gao Jiwei said that the current section of the LED filament lamp mainly uses glass substrate and sapphire substrate, the current yield of the whole lamp in 90%, also need to upgrade. "

Wang Peng introduction, lion lion photoelectric LED filament lamp according to different products and customer needs using different substrates, the current glass, sapphire, metal three substrates have been used to sapphire substrate. If the finished product yield sapphire substrate in the 80-90%, the use of glass substrate will be lower, lower than sapphire 5-10%, using metal substrate yield is higher, at about 95%. "

The yield of the whole lamp is very difficult to describe, because it involves multiple processes, if integrated to count, probably in the 93-94%, the sapphire substrate and the glass substrate yield, we only use the two kinds of substrate lamps. Dai Jian said.

Filament lamp is currently facing an important problem is that the cost is too high, one because of its process needs to be improved, the degree of automation is low, the second is the choice of materials, there are still some deviations. "Wang Peng said," this road filament lamp placed in front of who is a difficult road, but to go through this road is only a matter of time. "

To do a good job of LED filament lamp filament is not easy, even welding, sealing foam control, exhaust temperature, air inside gas type and concentration, in control, the whole temperature of the filament arrangement, power supply and the lamp scale, etc, have a lot of knowledge. Gao said to the Chinese LED network editor.

Filament lamp is not good to do, filament, drive, assembly is not good to do. But don't think it's a bad thing because it's not good. I believe that the market, the market is the final say. Filament lamp is currently faced with insufficient awareness and price is too high two issues, to solve these two problems that the amount of. "Dai Jian thinks. (text / China LED network Sophie)
