[Source: "High-tech LED" magazine June issue (total 54)] With the COB in each store in Zhongshan Guzhen vying for fresh, many packaging manufacturers have vicious competition, and hope that the COB market will come to a climax, I have a place in this wave.
In 2014, for many COB packaging manufacturers, the overall situation increased by 20-30% compared with the total production in 2013. Of course, there are a small number of manufacturers with less orders than in previous years, because the price war in 2014 was basically stable, but the reliability competition However, for most manufacturers, it will be a weakness. Compared with the world-class manufacturers Citizen, Sharp, Nichia, Everlight, Puri and Samsung, there is still a gap.
In 2004, Shenzhen Tongfang Optoelectronic Technology Co., Ltd. increased its sales in April and May by 45% to 8 million in the same period of the previous year, while the increase in customer volume was 15%. As a professional manufacturer of COB, Tongfang Optoelectronics is also actively exploring overseas markets, and its overseas sales volume has increased by 60%. For overseas markets, the same party photoelectric COB has passed EN62471 certification and LM80 certification, and has established a national laboratory to increase the reliability of its products. In the future, market competition will eventually return to the reliability competition of products. Only on the basis of high reliability can products win the recognition of customers, especially overseas customers. The requirements of overseas customers will now drive some manufacturers to shift from price to strength and win more orders in long-term cooperation.
At present, from the information collected by the same party from the sales department, the sales of COB will increase by 30% in the second half of the same period of last year, but it will not usher in. The climax that everyone expects will only rise steadily. Due to the fact that most of the manufacturers of Foshan traditional lamps have not yet undergone transformation, they are still in a wait-and-see state, and the transition is slow. The peak period should be in 2017-2 2009. China's lighting market will continue to maintain a growth rate of 10%, surpassing the growth rate of other markets. In 2014, the global LED commercial lighting market penetration rate is still rising rapidly, and the annual growth is expected to reach 23%. Analyze and organize the main market demand, product specifications and lighting manufacturer development strategies. As far as the market is concerned, commercial lighting uses LED tubes, spotlights, and bulbs as the main product applications; China is the most important area for LED commercial lighting in the world. The spotlights and bulbs can use COB light source, which becomes an irreplaceable product. In addition, the sales volume of downlights has been increasing at a rate of 25%. From the current sales analysis, the same side photoelectric does not appear. Talk season, has been welcoming the off-season with 15% growth.
At present, bulbs in COB packaging have occupied 40% to 50% of the market share of LED bulbs, and the ratio is expected to gradually expand. The market has begun to gradually accept COB light source, no longer in a wait-and-see state, and COB light source has outstanding advantages such as good heat dissipation performance and high cost performance, and is an important development direction of LED packaging in the future. Compared to SMD SMD packages and high power packages, COB packages offer significant advantages. In terms of performance, through reasonable design and construction of optical lenses, COB light source can effectively avoid spot light and glare, and can also effectively improve the color rendering index of the light source by changing the chip combination; in application, the COB light source makes the lamp Installation and production is simpler and more convenient, and can also improve the pass rate of finished lamps.
With the upstream chip manufacturers (Mainland Sanan and Taiwan Jingyuan), the demand in the Chinese market continues to increase, and at the same time, the price of the chip will be promoted. With the medium-power COB market, the price will be lowered by 10 -15%, while SMD's price advantage for COB will no longer exist, providing a reasonable price base for the use of COB. With the standardization of zhaga, it is gradually forming, making COB research and development, and confirming the direction in the future.
1. Maximum size (mechanical shape);
2. Fixing method (eg, fixed position of the screw, or a lamp holder);
3. The heat generated by the LED light engine and the maximum operating temperature;
4. The position and size of the light-emitting surface of the LED light engine related to the mirror of the luminaire;
5. Optical characteristics of the LED light engine: including light distribution, consistency and others;
6. Electrical characteristics (such as power supply voltage requirements, control methods).
The final quantitative production of COB will lock in resource-rich packaging manufacturers. At this time, the quality of COB will enter a relatively stable period, and the price war will play a significant role in the promotion of COB.
