Three reasons for the loss of technology direction in the LED industry

one of the reasons for the loss of technology direction: emphasizing production and neglecting research and development

at present, everyone's business is lagging behind. It's good to restart the screw (the speed is within 10r/min). Chip factories have broken the sky and calculated the area shortage of various geometric shapes. The price has begun to rise. Chips are often out of stock, and the factory operates 24 hours a day. Ask carefully, what is everyone doing? The most feedback is smd2835, smd5730, cob, flip cob and optical engine. Again, what are you going to do next year? According to the feedback of most enterprises, the expectation of next year is not yet obvious, and they may continue to make their current products. The problem reflected here is that the technical direction of the packaging enterprise is not clear, or more seriously, it has been lost. Most packaging plants have no R & D department, only engineering technology department. Engineers in the engineering technology department are mainly responsible for the improvement of poor production lines and process adjustment, and have no time to take into account the changes of chips, scaffold materials and other markets. The product line is basically to follow the big enterprises. What Cree, Philips and OSRAM do, we will follow up. In the early stage of industry development, when the technical route is not clear, it is indeed a good method to adopt the follow-up strategy to wait for the opening of the market. However, when LED has entered the homes of ordinary people, it is necessary to compete for product innovation. How to stand out among many enterprises and attract customers' attention. Many enterprises adopt the price strategy. As long as you dare to sell 1 yuan, it will immediately drop to 9 cents. After several rounds, everyone has no profit. The market has become a completely competitive market, and the production enterprises do not have the right to decide the price. At this time, the person in charge of the enterprise thinks about how to do it again? What new products? Looking back, after the subsidy fell, I found that in recent years, in addition to earning a pile of used equipment, supporting hundreds of employees, and paying millions of taxes, there was little left. This is still a more successful enterprise. Let's not talk about those who run away from bankruptcy. The enterprise found that the investment in technology research and development had been wasted due to busy production in these years, and found that there were no new products and technologies in hand. This leads to the above technical loss

the second reason for the loss of technological direction: downstream reverse guidance

customers will decide the resource allocation of the company. Because enterprises need to maintain product profits and invest limited resources in products that can produce more output, customers who buy such products virtually allocate resources for the company. The downstream Lighting Factory determines the product input and technical direction of the packaging factory. At present, most of the products made by LED lighting factories are still substitutes for traditional lamps, which leads to the direct PK cost performance of LED lighting products and traditional lamps. After decades of development from glass production to metal processing, traditional lamps have achieved technological optimization, cost optimization and relatively stable price. The popularity of LED lighting products has been less than a decade, and many technologies are still worth discussing. The insufficient industrialization of some technologies leads to high costs. In the process of competition with traditional lamp enterprises, lighting factories will put forward requirements for LED packaging devices: light efficiency, color quality, thermal conductivity and price. These factors will determine the resource investment of LED packaging plants: reducing costs or improving quality? Ordinary packaging factories first see the price and think that as long as the price is low, they can better develop customers. Therefore, packaging factories began to look for chip, bracket, glue, phosphor and other raw material manufacturers to reduce prices. The support was reduced from dozens of yuan/k to a few yuan/k, and it was completed in just two years. Chip factories are trying to increase equipment and expand factories to dilute high equipment investment. The competition among phosphor enterprises is more intense. Some enterprises have begun to give yellow phosphors free of charge (sold with red phosphors). Remember that the grand yellow phosphor sold for more than 20 yuan a gram. Another reason for the price reduction may be the formation of the qualifications of R & D personnel in the industrial chain. Most of the extension R & D personnel are formed by doctors from famous universities and overseas returnees (except for Beijing hukou). Chip R & D personnel generally have master's degrees. R & D engineers in packaging enterprises are mainly composed of undergraduate graduates. Lighting factories are mainly undergraduate and junior colleges. Most of the personnel who buy lamps are graduates of nine-year compulsory education. (the above part is not about discriminating against employees with low academic qualifications, but about controlling the technical details and direction. There are differences among employees with different academic qualifications, and there are also many employees in Vocational and technical colleges who are better than doctors). Doctoral students hope that undergraduate students can make requests, and undergraduate students need to ask junior high school students for technical feedback. Can this feedback mechanism find the correct technical problem points (except price)

the third reason for the loss of technical direction: does the rising curve become slow

the development of any technology cannot always seriously run on the same 45 ° curve, but the upward trend slowly slows down. The progress of LED technology is determined by the epitaxial mechanism, chip structure and packaging design. At present, blue and white LED chips are mainly on heterogeneous substrates (GaN is produced on sapphire substrates). The droop effect always exists, and the quantum well structure is basically finalized. Using graphic substrate, buffer layer optimization, surface coarsening, transparent conductive layer, current expansion layer and other methods to improve the overall performance of the product is getting smaller and smaller (it will certainly improve, but the range is small). The effects of yellowing resistance, refractive index improvement, bottom reflectivity and solid-state adhesive optimization of packaging materials are also getting smaller and smaller. Formed a relatively stable curve, leading enterprises to wait and see the next step of development

how to break the lost direction of technology

1. Adhere to the spirit of craftsmanship and find customers with high quality (not high profit margin). The direction of technological development is not terrible, but the terrible thing is that we have lost our ingenuity. Only high-quality customers can provide positive feedback, rather than blindly forcing the price. Get positive feedback to better find the product direction and match the technical direction

2. Pay attention to product research and development and technology research and development. The product R & D system maintains existing customers, and the technology R & D platform ensures the development of next-generation products. You need to settle down to do technology and become an engineer rather than a technician

3. Cautious investment in niche markets. At present, the concepts of infrared and ultraviolet are very hot, so it is recommended to invest cautiously. The niche market that everyone sees is an illusion. Once it enters, it becomes a red sea

4. Challenge products with thresholds. Having a technological threshold is a good thing. Enterprises need to overcome obstacles, and competitors also need to overcome them
