[High-tech LED reporter / Wang Cairong] "The global high-end and low-end LED lighting market is becoming more and more clear. Most of the low-end and mid-end markets will be occupied by Chinese lighting companies in the future. Most of the global LED lighting products will also be OEM or ODM by Chinese enterprises." Dr. Zhang Xiaofei, Chairman of Gaogong LED, analyzed and discussed the current trend of the LED lighting industry at the 2014 China LED Lighting Supply Chain Good Product Tour Symposium held in Foshan on the afternoon of May 16.
In the first half of 2014, the 2014 China LED Lighting Supply Chain Good Product Tour Symposium held by Gaogong LED has successively set foot in several major lighting industry towns such as Guangzhou, Xiamen, Hangzhou and Zhongshan, all of which have achieved great success. The fifth stage of the supply chain good product roving seminar continued to advance into Foshan City, one of the largest electric light source production bases in China, attracting nearly 150 LED lighting companies from the Pearl River Delta region including the local area.
In addition, sponsored by Foshan Kangrong Fine Ceramics Co., Ltd., the 2013 “Kangrong Cup†National LED Heatsink Design Competition hosted by Gaogong LED was in the semi-annual registration, primary selection, evaluation and final review stage. The final award results were announced at the second Foshan station seminar and an award ceremony was held.
The reshuffle will increase in the next three years, and the growth rate of output will slow down.
“In 2014, industry consolidation began to be obvious. The number of traditional lighting companies to LED lighting reached its peak. The number of LED-based companies will reach its peak, and the total number of LED companies will reach its peak.†Dr. Zhang Xiaofei at the meeting It is pointed out that some enterprises, especially small enterprises, will be integrated or eliminated. In 2015, the channel dispute is the most fierce. The traditional lighting enterprises on the scale are more likely to win. After the withdrawal of a large number of middle and downstream enterprises in 2016, they will appear. Ten billion comprehensive LED lighting companies.
In fact, today, LED lighting channels are fiercely competitive in the provincial and first-tier cities in the circulation field, but LED lighting companies still have opportunities in the third- and fourth-tier cities and county-level markets. Many lighting manufacturers have begun to look for them. Belong to your own market segment.
Whether it is an emerging LED lighting company or a traditional lighting company, it is looking for its own survival rules in the development process.
Dr. Zhang Xiaofei believes that most of the emerging LED lighting companies can neither do the scale nor the circulation field. Most of them are OEMs or ODMs for large domestic and foreign enterprises, and they must strive for better survival in the future market competition. Innovate continuously in technical processes, product forms and functions, and marketing models. Large traditional lighting companies need to quickly transfer and maintain channels, while small traditional lighting can focus on the lighting segment.
"In the future, the proportion of LED lighting industry affected by macro environment will increase, and the price of products in all links of the industry chain will drop rapidly. However, with the rapid growth of LED lighting output base, the growth rate of output value of the entire lighting industry will slow down in the next three years. Dr. Zhang Xiaofei said at the seminar that lighting companies should extend the product line horizontally, accelerate the frequency of product replacement, open up new market segments, and actively carry out systematic transformation of the marketing system, making full use of mobile Internet, O2O and other platforms to continuously improve Product premium ability.
Jingtai Optoelectronics PCT Materials Helps Cost-effective Packaging Products
In fact, one of the main reasons for the excellent performance of LED lighting products depends on the structural design of the packaged device and the use of materials and processes. In particular, scaffold materials that play a key role in heat conduction play a vital role in upgrading and improving product performance.
It is understood that the current package bracket is mainly composed of plastic, copper and electroplating, and the key to heat resistance is plastic material. At present, the main materials are PA6T, PA9T, PCT, EMC and so on.
Dr. Shao Pengrui, Technical Director of Jingtai Optoelectronics R&D Center, compared the cost performance of major materials such as PPA, EMC and PCT, said that PCT materials are superior to existing ones in high temperature endurance, high temperature long-term yellowing, reflectivity and UV irradiation. PPA, which can achieve unmatched color stability and low water absorption (about one thousandth) of other similar materials, can achieve good environmental adaptability.
“By comparing LM-80 with EMC, PCT 1W products are not lost to EMC 1W products. Currently, PCT raw material prices are more advantageous than EMC.†Dr. Shao Pengrui pointed out that PCT high temperature performance determines the heat dissipation requirements for lamps. It is not very demanding, which can reduce the cost of the radiator to a certain extent, and ultimately bring the high cost performance of the lamp. In addition, the PCT has various voltage schemes, covering 3-27V, which is convenient for cost-effective power supply design and ultimately reduces power supply cost.
Mingwei Electronics discusses the development trend and selection of LED power supply
As one of the important steps in determining the life and cost of LED whole lamp system, the importance of LED drive power has been neglected in recent years, but in recent years, as the focus of LED lighting market shifts from price competition to product quality, LED drive power Development trends and selection are getting more and more attention from LED lighting factories.
"The current LED driver power supply mainly includes isolated, non-isolated and linear cross-flow drives. The future development trend of drive power will be characterized by miniaturization, integrated de-energization and no stroboscopic intelligent development." Marketing director Zhao Chunbo said that the lamp bead and the outer casing are the two main factors affecting the LED drive power.
Zhao Chunbo said that in view of the future development trend of the above LED driving power supply, Mingwei Electronics has successively introduced various solutions such as SM7313P full patch integrated bulb lamp scheme, SM2087 integration scheme, SM7650, SM7630, SM208ND stroboscopic scheme, etc. The LED lighting market and the needs of customers are diversified.
Zhao Chunbo also introduced that in product design, Mingwei Electronics fully considers the performance and safety factors of power supply, uses innovative design to improve product performance, and then reduces product cost through large-scale production.
Overclocking three technology sharing high-power LED cooling solution
With the advancement of technology, the light effect and index of LED lamp beads have been significantly improved, but the problem of heat dissipation is still a stagnation of current LED lighting sources and lamps. If not handled properly, it is easy to cause LED lamps. Life and performance are greatly reduced.
Up to now, high-power LED lighting applications have become increasingly popular, covering a wide range of fields including streets, plazas, department stores and stadiums, and the scope of application is becoming wider and wider. However, due to the technical influence, the LED luminous efficiency is still low, and most of the energy is converted into thermal energy, which causes the LED light flux to drop, the efficiency is deteriorated, the chip aging is accelerated, and the life span is shortened. The heat dissipation problem has become the bottleneck of high-power LED technology in lighting engineering applications.
Wenkong Liang, director of overclocking technology engineering, said that overclocking technology has taken advantage of PC cooling technology for the heat dissipation of high-power LED lamps. Innovatively invented a series of heat-dissipating technologies such as heat pipe riveting, successfully solving the problem of high-power LED heat dissipation. “The 1000W floodlight cooling kit, the H-series mining lamp cooling kit, and the new industrial and mining lamp cooling kit have been launched, and are widely recognized by customers.â€
In addition, Overclocking III has established an optoelectronic laboratory, thermal laboratory and industrial design center to provide users with comprehensive and detailed engineering construction opinions and optical distribution analysis to maximize customer service.
Kang Rong Fine Ceramics - LED Ceramic Heatsink Solution Receives Attention
As we all know, LED lamps can only achieve stable luminous efficiency and quality under the good heat dissipation design, thereby reducing heat exhaustion and improving the life of products and peripheral components. In recent years, ceramic heat sinks have received wide attention in the industry due to their high insulation (15KV/mm), high thermal radiation (>0.95), high thermal conductivity, excellent electromagnetic compatibility, and thermal cycle stability.
There are three main ways of heat dissipation: conduction, convection, and radiation. The ceramic material itself has a high emissivity (>0.95) and a large microscopic specific surface area, which can promote the heat of the surface of the ceramic heat sink to the air. Jiang Rong, from Rongrong Ceramics Research and Development Center, pointed out at the seminar that the thermal conductivity of air is 0.03W/m·k at 75 °C. If there is no convection, the air conduction heat is very small, and the radiation heat determines the overall heat radiation. Therefore, in this case, ceramic materials have a unique heat dissipation advantage.
In Jiang Yan's view, LED lamps use ceramic heat-dissipating materials instead of metal materials to obtain more stable quality, simplify product system, reduce size, save system cost, and directly metal coating.
Optimize enterprise supply chain management strategy
The rapid increase in the penetration rate of the global LED lighting market is due to the breakthrough and rapid application of key LED technologies, and on the other hand, the optimal control of the supply chain cost. For domestic LED lighting companies, after experiencing the adverse consequences of a vicious price war, more and more lighting manufacturers began to try to optimize the product structure and accelerate the improvement of their own supply chain control.
“The concept of supply chain sounds quite complicated, but it is not difficult in fact. We can simplify it into two aspects: first, integrated management ideas and methods, and second, supply and demand management.†Zhou Shuiming, general manager of Jiamei Times Lighting Marketing In the speech of the seminar, the optimization of the lighting enterprise supply chain is mainly reflected in the cooperation management between suppliers, manufacturers, logistics providers, sellers, retailers and other enterprises, as well as the effective management of the internal departments of the enterprise.
After optimizing their own supply chain management, LED lighting companies can reduce inventory and costs on the one hand, and enhance the competitiveness of the industry to a considerable extent on the other hand, and predict and grasp future trends in a timely manner.
“The key to enterprise optimization supply chain management is to strengthen its understanding, attention and tactical needs, establish a supply chain management center, carefully grasp the implementation links and supply chain dynamics, and become the leading enterprise in the supply chain.†Zhou Shuiming stressed that enterprises are In the future development process, in any case, we must become an important part of the supply chain, in order to grasp a certain voice, so as to survive in the future shuffle.
