After nearly 10 years of development, China's LED packaging industry has a considerable output value, and has become one of the world's major LED packaging production bases. The LED phosphor industry, which is compatible with LED packaging, has developed rapidly in recent years. According to the survey of high-tech LEDs, as of December 2012, there are more than 60 LED phosphor suppliers with a certain sales scale in China, mainly distributed in various Chinese-funded, Taiwan-funded, US-funded phosphor companies. Among them, there are more than 15 local enterprises in China, and some LED phosphors have sold more than 100 kg/month.
After several years of rapid development, the overall quality of LED phosphor products has been greatly improved. Due to technical limitations, China's domestic LED phosphors still have a certain gap between quality and international level. At present, there are still a lot of inferior LED phosphor products on the market. From the perspective of the needs of LED packaging companies, local LED phosphors can not fully meet market requirements, especially in the field of high-end phosphors.
It is expected that many companies will enter the LED phosphor industry in the next few years. However, many companies and other investors did not understand the actual situation of the current industry when they entered the LED phosphor field, and lacked accurate data related to the Chinese LED phosphor industry.
In 2012, Gaogong LED collected a large amount of first-hand information through the field investigation of the world's major LED phosphor suppliers and LED packaging companies, and the face-to-face interviews with the LED phosphor industry leaders, which laid the foundation for the preparation of this report. solid foundation.
This report has carried out detailed research and analysis on the development characteristics, main products, output value and investment opportunities of China's LED phosphor industry in 2012. Gaogong LED hopes to provide the most accurate and optimal reference value report for investors, industry insiders, securities companies and those who want to learn about the LED phosphor industry through actual research.

As LCD display in YFJ company that we usually use it to military grade battery ,especially Lithium-ion batteries ,for these battery applications ,we have obvious advantage is that we focus more on shor circuit protection which we follow the US military standard.
Short circuit protection:The following test shall be performed. Charge batteriesas specified in ; use of 4.6.3 is permitted. Measure and record the OCV. Short each battery across all the positive and negative terminals with a total external resistance not greater than 50 milliohms. After one hour remove the short from across the terminals. Measure and record the OCV. Stabilize batteries at the normal conditions of 4.3.1 for not less than 2 hours. Chargebatteries in accordance with 4.6; use of 4.6.3 is permitted. Stabilize batteries at normal conditions for not less than 2 hours, then discharge the battery in accordance with 4.7.2.3. The battery shall meet the requirements of 3.7.2.3.
