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.

GM announced that its Cadillac ELR's external light source uses LED lighting, which means that Cadillac EUR will be the world's first electric vehicle that uses LEDs for all external lighting.
The advantages of LED lighting are obvious, and a lot of applications have begun to be used in automotive lighting. China's automobile production and sales volume are very large. According to the statistics of China Association of Automobile Manufacturers, China's automobile production and sales last year were 19,217,800 and 19,390,400, respectively, up 4.6 and 4.3 respectively, driving the booming of related auto parts industry, including LED vehicles. The growth rate of lighting is nearly 10 times the sum of production and sales.
According to the Ministry of Industry and Information Technology, as of the end of 2015, automotive lighting needs to meet the carbon dioxide emission reduction targets. LEDs have the advantages of long life, high brightness and low energy consumption. Applications in automobiles can reduce energy consumption. In addition, LED lights can withstand higher intensity stroboscopic, which plays an important role in automotive lighting; LED lamps have shorter response times, which can also effectively reduce reaction time and reduce traffic accidents.
However, there are not many related companies in China, and the technical strength is not strong enough, which creates opportunities for other manufacturers. After seeing this market, LED lighting manufacturers and European and American manufacturers in Taiwan have also begun to enter the mainland automotive LED lighting market.
LED lighting companies in Taiwan have set off a wave of transformation to automotive lighting last year. Including the old companies such as Jingdian, Yuyuan, AUO, Dongbei, etc., they have extended their business to international auto brands, and take advantage of the mainland labor cost to actively invest in the mainland to build factories and accelerate their own LED lighting. The pace of development in the field.
