Analysis of the current situation of the LED lighting

From the first incandescent lamp lights the world, to the LED lamp set off a new wave of green, the human exploration of lighting technology has experienced a long developing history. Today, when the different lighting requirements can be very good to meet the future direction of development, the most important lighting is clearer -- that is the "energy saving".

There is a certain gap and general lighting costs; LED topic now is very hot, the LED lighting industry, we must be objective, calmly look at the problem, because it is ultimately pay for old people. America treated LED lighting project is more rational. After all, LED lighting has short board -- most notably the cost problem.

LED lighting cost remains high, about 10 times as expensive than ordinary lighting. Experts said, the cost will certainly be lower gradually along with the development of technology progress and market. On the one hand, with the development of material, equipment depreciation / maintenance, advanced R & D cost along with the increase of output decreased gradually, on the other hand, the growth of an epitaxial structure design, process, chip manufacturing and processing technology improvement, application package after maturity is bound to make the LED chip yield enhancement, thus reducing the cost of. The question is, can be reduced to what extent? From material, process, maintain a variety of ways, LED lights to reduce close to the ordinary lighting costs, will be a very long process. Looking to the future, if the light effect reached 200 lumens / watt, costs can be reduced to 5 times the ordinary lighting, market Is it right? Will show the development of faster?

In addition, for municipal lighting and so on large system lighting engineering, LED the lamp itself cost is on the one hand, the cost of the system can be effectively reduced is also a problem, the design of LED lighting systems have a certain degree of complexity, all aspects of the understanding of the LED technology, the outdoor lighting system, familiar to circuit design knowledge and so on the knowledge and experience will influence design quality and the final effect. This put forward higher requirement for the implementation of the project, if the future of the birth of a more professional team to accomplish this task, but also the inevitable result of costs.

LED lighting device development speed is too fast, there is certain difficulty standards". In addition, standard setting and also taking into account the problem in line with international standards. Multiple reference American energy department, International Institute of lighting IES body work, learn from each other, which adapt to the situation of our country, but also with the international synchronization. Believe that local enterprises jointly Taiwan, Hongkong together to formulate the standard applicable to the Greater China region is even more desirable.

Patent is the core competitiveness. For the majority of local enterprises, R & D investment is little, the research on the application fields and market is not enough, so the patent issues need to be solved. Obtain a patent license threshold is not high. LED lighting is related to many basic disciplines of patent, patent cross, high complexity, but in general, the risk is there, but in the short term will not be an obstacle.

Focus on the maximization can achieve the overall benefit from the "system". For example, the power company, it stands to reason that it should not support LED lighting, after all, the sale of electricity more will have more money. But the government has adopted a "method of subsidies for electricity, the power company" by saving the money saved by the government paid subsidies. In particular, the peak period of electricity on the power company is a great challenge, through the use of LED lamp can alleviate the peak power consumption, the lower the peak value of power saved money, government supply electric power company. In this way, the power company is from "negative" power to drive the LED energy saving lighting "positive" force.

In such USA, LED technology has been quite mature and people into a life. LED night lamp store launched the hit "spends 2 cents" slogan, known as the power consumption is only 0.001082 watts. Compared to shout slogans, this shows that the problems of digital propaganda, is undoubtedly more attractive to consumers.

Now the market is undoubtedly a very good opportunity, promote the economic stimulus plan, the Chinese government has is a big cake for the 7/1000 of GDP for the lighting market, concentrating on the technology and application of research and development of the company will certainly be able to find their own market. But challenges also coexist. Strong background in chemical material, Nichia Osram; leading technology, extensive product line complete Cree; rich Philips, GE and almost LED semiconductor lighting market, Chinese local enterprises must overcome these technical leading enterprise by the pressure, to change a technology with the market road or stand on one's own development path according to their own situation. On the one hand, the international giants can easily eat up part of the market share, making the whole industry competition, profits diluted, those who do not have the core competitiveness of enterprises will be squeezed out. On the other hand, local enterprises of their own on the market demand grasp enough, R & D of materials and application of investment is very small, very difficult to resist the fierce market competition.

Government support can play a certain role, the fundamental solution is the work hard to the enterprise, also carried out extensive cooperation with the University, Research Institute, with the most convenient way to technology into productivity.
