On October 25, the 6th (Shenzhen) LED General Lighting Driving Technology Seminar hosted by Big Bit Information Organization and undertaken by Semiconductor Device Application Network (for details, please visit http://ic.big-bit.com/hdbd/led_6j /index.html), will be held at Marco Polo Shenzhen Hotel.
Before the meeting, Big Bit reporter interviewed Yuan Yuxiang, director of the technical department of Guangzhou Jiufo Electric Co., Ltd.
Guangzhou Jiufo Electric Appliance Co., Ltd. is an enterprise with more than 20 years of professional production of fluorescent lamps, emergency lamps, energy-saving lamps, fluorescent lamp inductors and other lighting products. It is one of the largest enterprises in China producing fluorescent lamps and fluorescent lamp ballast products.
Yuan Yuxiang participated in the third meeting held by Big Bit. He said: "Now recalling, I think the previous conferences are very good. As for the last power supply conference, I think it is very good, and I participated in Another session is also possible. The content of the meeting is very accurate and well managed. "
When talking about his impressions of Dabit, Mr. Yuan said: "The service is very good, good and good. Every time Dabit will notify me in advance, I can get the information immediately, and the service before the meeting is more thoughtful and better."
Speaking of the LED lighting industry, he said that the entire LED industry is chaotic, and the quality of the products is uneven. However, with regard to the development prospects of the LED lighting industry, he said: "I am optimistic about the development prospects of the LED general lighting industry, because now the whole country is in this direction, but the LED industry still needs to be developed, not to say it will be all right. . "
He said that the key to LED lighting is how to control the quality, and this quality is mainly reflected in the consistency, because the current LED lighting is difficult to do a good job of temperature consistency. In general, the consistency of the solution temperature is that many manufacturers can't do it, and can't do it well. For example, the original range is 270k-6500k, and the manufacturer wants 300k, but some people do 270k, 300k, and some people do almost 7000k. In this respect, this consistency is relatively poor.
Although the "temperature uniformity" mentioned by Yuan Yuxiang is indeed a big problem, the consistency of the LED lighting temperature is difficult to control. During the divergence process, you need to find a way to control the temperature consistency. Therefore, this is exactly the direction in which manufacturers need to make efforts.
After discussing the problem of temperature consistency, Mr. Yuan added one more point, he said: "The most talked about in the LED lighting industry is the heat dissipation problem. As long as the heat dissipation is done, then its reliability and stability will be good. For heat dissipation, he also said that heat dissipation materials have a greater impact on the production process. The key lies in the purity of the material. If the purity of the material is not high, it not only affects the production process, but also affects the stability of LED lighting, and its efficiency and other aspects will also have a certain impact.
Finally, returning to the topic of the meeting, Yuan Yuxiang said: "The most important thing we are attending this meeting is the power supply design. Power supply design is an important part for LED. Because the last meeting brought us new inspiration for lighting products, It ’s mainly the design. So I look forward to getting more information about the power supply this time, for example, to understand the new features and design of the power supply. "
