[High-tech LED reporter / Yue Mengdi] This year's LED lighting application demand growth is obvious, the market situation is more clear than last year. Since the end of last year, the overall benefits of both listed companies and small and medium-sized enterprises have increased significantly.
However, the current market competition is fierce and disorderly, the transformation of traditional lighting enterprises, the unregulated product technology, and the limited sharing of resources inside and outside the industry restrict the development of the domestic LED lighting supply chain.
According to data from the High-Tech LED Industry Research Institute (GLII), by 2017, the global LED general lighting penetration rate will reach 62.8%, and most of the low-end and mid-end markets will be occupied by Chinese lighting companies.
On the afternoon of July 8, “2014 China LED Lighting Supply Chain Good Product Tour Seminar--Shenzhen Station†was held in the International Ballroom on the 4th floor of Shenzhen Qian'an International Hotel. Dr. Zhang Xiaofei, Chairman of Gaogong LED, analyzed at the meeting: “The global high-end and low-end LED lighting market has a clear-cut phenomenon, and most of the lighting products will be OEM or ODM by Chinese enterprises.â€
Dr. Shao Pengrui, Technical Director of Jingtai Co., Ltd., Xu Chonggao, Quality Manager of Xuyu Optoelectronics, Li Zhaohua, Deputy General Manager of Mingwei Electronics, Ding Rui, Saudi Basic Application Development Manager, Jane Yucang, General Manager of Confucian Electronics, and Lu Guoming, General Manager of Tengsheng Control Glue Excellent corporate guests in all aspects of the lighting supply chain gave keynote speeches on issues related to all aspects of the supply chain.
Dr. Zhang Xiaofei said that Gaogong LED hopes to provide a platform for the conference to integrate the cost-effective lighting source and key components and accessories manufacturers in mainland China. Through the quality upgrade strategy, the lighting supply chain channel will be further optimized and the LED will be strengthened. Lighting companies screen and introduce high-quality, cost-effective upstream components and lighting accessories resources to enhance the added value of LED lighting companies.
Shares polycrystalline table: PCT obvious advantages <br> <br> material It is understood that the current package is mainly composed of a plastic holder, and copper electroplating, but the key is that the heat-resistant plastic material, the main material: PA6T, PA9T, PCT, EMC, etc.
The quality of LED lighting products has a lot to do with the design of its packaged devices and the use of materials and processes. In particular, the scaffold material, which plays a key role in heat conduction, plays a vital role in upgrading the performance of LED lighting products.
Dr. Shao Pengrui, Technical Director of Jingtai Co., Ltd. said that from the perspective of lumen maintenance, PCT 1W and EMC 1W products have comparable performance, but PCT raw material prices are now more advantageous than EMC. However, PCT materials are superior to existing PPA in terms of high temperature resistance and water absorption, and have excellent properties such as low yellowing and relatively easy forming, and the performance of products above 0.5W is more guaranteed.
Asahi Optical: cost-effective lamp beads selection is the key <br> <br> market attention on the increasing light. However, many LED lighting manufacturers still lack a complete evaluation system when selecting LED lamp beads. In the face of uneven quality LED packaging manufacturers, some enterprises are hesitant to choose LED lamp beads.
How to choose cost-effective LED lamp beads? Xu Yuguang, the quality manager of Xuyu Optoelectronics, believes that packaging companies should do a good job of lighting beads. Lamp beads include chips, brackets, glue and phosphors, all of which are related to the quality of the light source.
In terms of lamp price, for example, 5630, Samsung's 300 yuan / k, domestically may sell more than 100 yuan. Brand influence, company size and product stability all have an impact on prices.
The stability of the product is linked to reliability. In general, companies will test to determine whether the product is reliable, but Zhai Chongao said that cost-effective lamp beads are generally not enough to pass the aging test, but require specific high temperature and high humidity aging tests.
Ming Microelectronics: innovative design and scale both <br> <br> recent years, with the focus LED lighting market by price competition gradually go to product quality, the decision as an important part of the whole LED lamp life and system cost one, The development trend and selection of LED driving power sources are getting more and more attention from LED lighting factories.
In view of the future development trend of the above LED driving power supply, Li Zhaohua, deputy general manager of Mingwei Electronics, proposed at the meeting that Mingwei Electronics will use innovative design to improve product performance and reduce product cost through large-scale production. And has introduced the SM7313P full patch integrated bulb lamp solution, SM2087 integration solution, SM7650, SM7630, SM208ND stroboscopic solution and other solutions to meet the diversification of LED lighting market and customer needs.
SABIC Innovative Plastics: plastic <br> <br> highlighted the role of innovation is the core competitiveness of enterprises. It is understood that the Saudi foundation is the world leader in blow molding technology, and can guarantee 96.5% light reflectance in the thinness of 0.3 mm, which is one of the most favorable factors in LED lighting design products. Recently, Saudi Basic Innovative Plastics has launched a new innovative plastics such as specialty resins.
Ding Rui, Saudi Basic Application Development Manager, analyzed the application and development prospects of innovative engineering plastics in the LED industry. According to reports, Lexan flame retardant polycarbonate resin provides excellent light transmission and good light diffusion, suitable for LED optical applications. At the same time, Lexan flame retardant resins have higher thermal properties than standard polycarbonates. Because it does not use any bromination or chlorination additives, it has good flame retardancy and is more in line with UL certification standards.
Ru is an electron: LED heat innovation subvert the traditional thinking <br> <br> It is understood that the best conventional thermally conductive material within the thermal conductivity 2.5w / (m · k), with respect to the thermal conductivity of the LED itself rapid cooling The demand must be tens or even hundreds of times different. The result is sometimes that the chip beads are hot and the heat is dissipated.
The LED lamp can only achieve stable luminous efficiency and quality under the good heat dissipation design, thereby reducing heat exhaustion and improving the life of the product and peripheral components.
At the meeting, Confucian Electronics General Manager Jian Yucang discussed the current domestic LED heat dissipation and shared the current Confucian Electronics' new technologies and new achievements in LED heat dissipation: thermoelectric separation and polishing mirror COB technology, discrete thermoelectric separation MPCB and CIB light source.
Teng Sheng-controlled glue: LED packaging localization trend evident dispensing equipment <br> <br> Teng-sheng, general manager Lu Guoming control glue and finally we discussed the "high-precision, high-performance fully automated intelligent dispensing solutions."
At present, the development status of the domestic dispensing industry is that the single-component dispensing technology is relatively mature, and its development direction is gradually transitioning to automation and high precision. Lu Guoming believes that the trend of localization of LED packaging and dispensing equipment is becoming more and more obvious, and the phenomenon of increasing profits will still exist, and the competition between packaging companies will become more intense. But in his view, the market space that can be tapped is still huge.
In response to the market's intelligent demand, Tengsheng Controlled Plastics has launched a highly intelligent LED dispensing machine--FAD9400, which has a one-button debugging function and a closed-loop automatic detection and compensation system for dispensing, which greatly reduces the technical dependence on operators.
During the round-table dialogue, Dr. Zhang Xiaofei and the speakers expressed their opinions and opinions on how to optimize the supply chain and create differentiated and competitive products for LED lighting companies, and also caused heated discussions among the participants.
However, the current market competition is fierce and disorderly, the transformation of traditional lighting enterprises, the unregulated product technology, and the limited sharing of resources inside and outside the industry restrict the development of the domestic LED lighting supply chain.

Mobile Phone Headset is a pair of switching units that accept the electrical signals from a media player or receiver and convert them into audible sound waves using a speaker close to the ear. The headset is typically detachable from the media player and is connected by a plug. The advantage is that you can listen to the sound alone without affecting others; you can also separate the sound of the surrounding environment.
Mobile phone headset maintenance and care notes:
1: Be sure to lower the volume before use. If the volume of your output device is too large, not only damage ears, but also diaphragm folds, or even burne the voice coil of the earphone.
2: The earphones are away from strong magnets. The magnetic properties of the magnet of the unit will drop, and the sensitivity will decrease over time.
3: The earphones are away from moisture. The pads in the earphone unit will be rusted, the resistance will increase, and your earphones will be biased.
4: Keep away from chemicals. The outer casing of the earphone is very soluble in organic chemicals, so it is not good to look at it.
