Last month, visited a lot of the LED industry enterprises. Which is given priority to with packaging companies, lighting, lighting and power supply enterprises also have several.

Casual talk about your chat with so many bosses or technical director feelings and their own reflection, only for the personal view.

Technical factor: the lost in the direction of the research, production, light weight.

Now everybody business is pretty good, fab ground-breaking began to rise, chips are often out of stock, factory 24 hours a day to operate. Careful questioning, everyone was doing? The most feedback is: SMD2835, SMD5730, COB, inversion COB light engine. Ask again, going to do next year? Feedback, most enterprises is expected next year also didn't look at, is likely to continue to do the product. Response to the problem is here, the packaging enterprise technical direction is not clear, or serious point has been lost.

Most of the assembly house no r&d department, engineering department only. The engineer in engineering department is primarily responsible for the improvement of the poor production line and process adjustment, busy chip, the change of scaffold materials and other markets. Product line is basically walked with large enterprises, CREE, PHILIPS, OSRAM companies do, we will follow up. This at the beginning of the industrial development, technical route is not clear when the following strategy is used to wait for the market to open, is indeed a very good method. However, when the LED has entered the common common people, competing product innovations will be needed. How to stand out in many enterprises attract the attention of the customer. Many enterprises adopt the strategy of price, as long as you dare to sell 1 piece, to 9 hair soon. A few rounds down everybody don't have any profit. Market into a perfect competition market, manufacturing enterprises do not have the price of the decision. At this time, the enterprise, head to think how to do it? Do any of the new product? Looked back and found these years in addition to earn a pile has become a second-hand equipment, feed several hundred employees, hand over the left after millions of taxes and fees. This is a successful enterprise. Bankruptcy run is not to say. Enterprise found from these years abandoned due to busy production technology research and development investment, that is did not take out the new products, new technology. This creates a more lost technology.

Lost the direction of the technology causes # 2: the downstream reverse guide?

The customer will decide the allocation of resources of the company. Because companies need to maintain the product profit is the limited resources into can have more output of products, to buy this kind of products for the company customers in virtually made the allocation of resources. Downstream of the lighting factory determines the product of the assembly house investment and technology direction. Most of the products due to the LED lighting factory is still replace traditional lamps and lanterns, LED to the LED lighting products and traditional lamps and lanterns PK value directly. Traditional lamps and lanterns from glass to metal processing after decades, nearly hundred years of development has reached the technical optimization, cost optimization and formed a relatively stable price. The popularity of LED lighting products is less than 10 years, a lot of technology is still worth discussing, insufficient part technology industrialization leads to higher cost. Lighting factory in traditional and lamps and lanterns is in the process of the enterprise competition of LED encapsulation device request: luminous efficacy, color quality, heat conduction performance and price. These factors will determine the resources of the LED assembly house: cost reduction or improve quality? General assembly house to see the first price, think that as long as the price is low can better develop the customer. To find it and assembly house chips, stents, glue, phosphor and other raw materials manufacturers to lower prices. Stents reduced to a few dollars from dozens of yuan/K/K, will be finished in just two years. Chip plant in an effort to increase equipment, expanding factory to diluted high equipment investment. Phosphor enterprises more competitive, some companies yellow phosphor already free (match pretty in sales), still remember that year grand yellow phosphor selling more than 20 pieces of a gram. Interacting, another reason may be: the formation of the industry chain research and development personnel qualification. Dr Extension developers mostly famous university and ast form (except Beijing hukou), chip developers generally degree is master degree, encapsulation enterprise r&d engineers consist mostly of undergraduate course graduate, lighting factory is given priority to with undergraduate course and specialized subject, buy light most of the staff is graduate of nine-year compulsory education. (the above part is not to say that low degree of discrimination, but the technical details and the direction of the charged with different educational background, there is a difference between also has a lot of vocational and technical college staff than Dr Severe). Doctoral hope undergraduate request, undergraduate students need to find a junior high school students ask technical feedback. The feedback mechanism can find the right technical problems point (in addition to the price)?

Lost the direction of the technology causes # 3: rising curve become slow?

The development of any technology can't always serious in running the same article 45 ° Angle curve, but slowly slow upward trend. The progress of LED technology and chip structure by the extension institutions and packaging design decision. The blue white LED chip is heterogeneous substrate (GaN on sapphire substrate production) Droop effect is always present, quantum well structure basic finalize the design. Using graphical substrate, the optimization of buffer layer, surface roughening, transparent conductive layer, current extension and so on methods for improving the overall performance of products is more and more small, will surely improve, just small amplitude). Packaging materials of resistance to yellowing, refractive index, reflectivity, solid crystal at the bottom of the glue to optimize these effects is also smaller and smaller. Formed a relatively smooth curve, can lead to the development of enterprises are waiting to see the next step.

How to break the technical direction?

1, adhere to the spirit, to find good quality (not high profit margins) customers. Technology development direction is not terrible, terrible is that we lost the originality. Only high quality customers can put forward positive feedback rather than blindly to the price of persecution. Positive feedback to better looking for product direction, matching technology direction.

2, pay attention to product research and development, technology research and development. Product research and development system to maintain existing customers, ensure that the next generation of product development technology research and development platform. Need to do technology, focused practice into engineers rather than technicians.

3, niche market cautious investment. Infrared, ultraviolet, the concept is very hot, recommend careful investment. Everyone see illusion, niche market is ChengGongHai after the baby.

4, challenges have threshold of products. It is good to have technical threshold, the enterprises to overcome the need to cross obstacle, competitors also need.
