The LED demand market continues to be optimistic, and the mid-stream package is now a new round of capacity expansion.
Following the announcement of Zhaochi's new 1000 LED packaging production line in Nanchang, on June 30, Yimeixinguang high-quality LED device module project will be settled in Nanchang High-tech Zone, with a total investment of 2 billion. The first phase is planned to be 300 packages. And the module line, after the completion of production, it is expected to increase the annual output value of over 1 billion yuan.
“Yimeixinguang is a leading innovation enterprise in LED in North China. It is a well-known brand of high-quality LED devices and modules. It has established LED R&D and production base in Beijing Economic and Technological Development Zone. This time, the company increased its capital and expanded production in the high-tech zone. It will form a dual base between Beijing and Nanchang, take advantage of Beijing's R&D and internationalization, combine Nanchang's geographical advantages and industrial advantages, and accelerate the expansion of Yimeixinguang's high-quality LED packaging devices and module components. Dr. Fan Zhencan, President, said.
At the same time, Zhaochi shares announced on June 29 that the company will invest no less than RMB 1.5 billion and no more than RMB 1.6 billion to invest in LED epitaxial wafer and chip production projects in Nanchang High-tech Industrial Development Zone. The first phase of the project plans to jointly invest RMB 5 billion (including construction land, plant construction and renovation costs), of which the equipment investment is not less than RMB 3 billion.
Jiangxi Province Zhaochi Photoelectric Co., Ltd., a wholly-owned subsidiary of Zhaochi Energy, has applied for the construction of LED packaging project to apply for key industry development funds. The investment amount of the Industrial Development Fund is RMB 700 million. The capital increase will be used to add 1,000 LED packaging production lines to Jiangxi Zhaochi.
The background of this capacity expansion has a certain difference from the previous round of expansion. Compared with the previous round of "civil war", this round of capacity expansion is directed at the competition among the top ten in the world. Leading companies including Sanan Optoelectronics, Huacan Optoelectronics, Hongli Zhihui, Guoxing Optoelectronics, and Mulinsen have completed a new round of expansion plans.
In recent years, with the continuous increase of LED penetration rate, the growth rate of the global LED industry is gradually slowing down. In the Chinese market, the market share of LED chip manufacturers has exceeded 70%, and the global packaging capacity is also accelerating to China. In 2017, mainland packaging capacity will continue to grow.
Long wave pass filters are usually used for wavelength order classification. One side is plated with hard medium long wave pass filter film and the other side is plated with antireflection film, which can cut off sharp light at a specific wavelength, while the other wavelength region has high transmission, so as to achieve the purpose of isolating a wide region of the spectrum
Filter is an optical device used to select the required radiation band. A common feature of filters is that no filter can make the imaging of celestial bodies brighter, because all filters will absorb certain wavelengths, making objects darker.
The filter is made of plastic or glass with special dyes. The red filter can only let the red light pass through, and so on. The transmittance of glass sheet is similar to that of air, and all colored light can pass through, so it is transparent. However, after dyeing with dye, the molecular structure changes, the refractive index also changes, and the passage of some colored light changes. For example, when a white light passes through a blue filter, it emits a blue light, while there are very few green and red light, and most of them are absorbed by the filter.
