The working principle of a reaction kettle is to place a reaction solvent in the inner layer for stirring reaction, and the interlayer can be connected to different cold and heat sources (frozen liquid, hot water or hot oil) for circulating heating or cooling reaction. Inject a constant temperature (high or low temperature) hot melt medium or cooling medium through the interlayer of the reactor to heat or cool the materials inside the reactor at a constant temperature. At the same time, stirring reactions can be carried out under normal or negative pressure conditions according to usage requirements. The material reacts in the reactor and can control the evaporation and reflux of the reaction solution. After the reaction is completed, the material can be discharged from the discharge port at the bottom of the reactor, making the operation extremely convenient.

LED is undoubtedly the most mainstream lighting source in the world. As the saying goes, the ad slogan of Adidas (no brothers, no basketball) is called: no LED, no lighting. Whether it is international lighting brands such as Osram, Philips, Panasonic, or domestic leading companies such as NVC, Sanxiong Aurora, Dehao Runda, Sanan Optoelectronics, etc., are all in the middle of the LED industry chain. According to statistics, in 2013, the total output value of China's LED industry reached 263.8 billion yuan, a year-on-year increase of 28. Among them, the output value of LED upstream epitaxial chips, midstream packaging and downstream applications were 8.4 billion yuan, 47.3 billion yuan, and 208.1 billion yuan, respectively. 17, 19, 31.
In 2014, the rapid penetration period of LED lighting will be ushered in. It is expected that the output value of the industry will exceed 320 billion yuan, an increase of more than 20. Especially in the commercial and civil lighting field, the market penetration rate will reach 20-30.
The market capacity is so large that all companies inside and outside the industry are eager for LEDs. However, compared with traditional lighting sources, China's LED industry and enterprises still have several common shortcomings: First, the overall lack of LED core technology, especially LED chip technology; Second, product development and innovation capabilities are generally weak, still only The replacement application of the traditional light source does not give play to the individualized advantages of LED lighting; the third is that the adaptability of the LED lighting technology is constantly updated, and the forward-looking is not strong. LED lighting belongs to the technology-based and capital-based industries. The technology is changing with each passing day and the speed of upgrading is much higher than that of traditional light sources. Some experts even predict that after 3-5 years of blowout period, the LED market will have a clear pattern of survival of the fittest. Industry concentration will be formed rapidly. Therefore, how can China's LED lighting companies focus on the longer-term future and focus on more advanced lighting technologies?
