At this stage, both domestic and foreign LED lighting industry is developing rapidly. However, behind the rapid development, China's LED lighting industry has exposed problems such as lack of core technology, insufficient innovation capability, and disorderly market competition. The specific performance is as follows:

One: In terms of output value, the current penetration rate of LED in the domestic lighting market is only 5, and the core technology relies on imports, and the overall cost has become a stumbling block to the further development of the LED industry. LED chips are like the engine of a car. The lack of core technology will directly constrain the development of this industry. It is understood that the main technologies for LED upstream chip production are in the hands of foreign companies, and the process of localization of technology is slow, which has affected the development of the industry. MOCVD epitaxial furnace and its related supporting technology are the highest end of the LED industry chain. At present, it mainly relies on imports, which greatly restricts the cost control of the upstream of the LED industry.
Second: As far as the overall level is concerned, there is still a gap of two years between China and the international first-class level. Many developed countries and developing countries or regions in the world are accelerating the development of semiconductor lighting technology and industry. In terms of technology, China is in the second echelon.
Third: Blind investment and lack of core technology make China's LED lighting market mixed, and the quality is mixed. Unstable quality is also a common problem faced by LED companies. At present, there are many small and medium-sized enterprises producing low-quality products in the LED lighting market, and the industry pattern is unstable.
Four: As international giant manufacturers enter the Chinese market, many domestic enterprises with certain core competitiveness will face the risk of being merged, and enterprises that lack competitiveness will be directly eliminated. If we do not regulate the market, the future will likely fall to the point of making wedding dresses for foreign lighting giants.
How can we solve a lot of industry defects and hidden dangers?
According to the analysis of many experts, the following suggestions are made:
I. Strengthen the country's overall guidance for local LED industry planning, and issue national industry standards as soon as possible, especially the industry standards for related products in demonstration projects, such as street lights, tunnel lights, display screens, landscape lights, etc., so that local governments can purchase There are standards for products provided by companies.
Second: the market competition is becoming increasingly fierce, and it is imperative to strengthen the research and development of the next generation of semiconductor lighting technology. At the same time, the localization of MOCVD for semiconductor lighting core equipment will be realized as soon as possible, fundamentally changing the situation of high-end equipment and attracting people, and promoting the rapid, healthy and sustainable development of China's semiconductor lighting strategic emerging industries. We will introduce relevant supporting policies as soon as possible, strengthen the establishment and standardization of testing institutions, avoid some non-conforming test results, and improve the overall testing level and credibility.
The Introduction of PCD
The PCD (Polycrystalline diamond) is a composite material, consisting of sintered diamond particles with a metallic binder. Diamond is the hardest material in absolute terms and therefore also the most resistant to abrasion. Used as a cutting tool, it has a good wear resistance, and a yield superior to traditional sharp carbide. The machined surface roughness with the PCD can reach comparable to the adjustment.
Main applications
â–²Processing of non-ferrous
â–²Aluminum alloys with high or low silicon content (pistons, engine blocks engine, wheels, carburetors, connecting rods, gear boxes, cylinders for brakes, etc.).
â–²Bronze and copper alloys (copper manifolds, engine bearings, bushings, connecting rods eyes, locations pumps etc.).
â–²Tungsten carbide (trafilatori rollers and other components sintered etc).
â–²Pieces composed of aluminum and lead, aluminum engine blocks with cast iron pipes reported
â–²Processing of non-metallic materials
â–²Very abrasive materials, such as ceramics industrial uncooked.
â–²Some fired ceramic: zirconia aluminum oxide, such as spark plugs and insulators.
â–²Glass, plastics with glass fibers, carbon fibers.
The Introduction of PCBN
PCBN has the characteristics of high thermal stability, high hardness, high wear resistance and. It`s inert to iron family element, hence PCBN is mainly used for the machining of high hardness and hard processed ferrous materials, such as d facing alloys, harden steel, pearlitic gray cast iron, high temperature alloy, high-speed steel, hard facing alloys, Ni-Cr alloy, powder metallurgy metals.
