Recently, the development prospects of LED light sources have been questioned again, "energy saving is not saving money", "neither energy saving nor saving money", "revelation of the sequelae of the carnival", "following the mistakes of the photovoltaic industry," the full application of public lighting is dangerous ", etc. Frequently said, LED light source is in a deadlock, and it is urgent for industry professionals to answer their questions.
LED light source is in a deadlock
Yesterday, "Taichung Broadcasting" reported that the Taichung City Council of Taiwan, after reviewing the budget, decided to delete the 79 million LED subsidy from the central government. The news attracted a lot of attention. It is understood that the city councilman Li Zhong said that the Led Street Light has insufficient illumination and the failure rate is very high. High, the central government subsidizes the installation, and has to pay maintenance fees in the future, which does not really achieve the purpose of saving money.
Coincidentally, Guangdong ’s efforts to promote public lighting in the past three years have been strongly questioned again. Industry insiders believe that regional mandatory replacement of LED lighting products with immature technology and low technology content makes people unavoidable. More importantly, the products need to consume a lot of non-ferrous metal resources, which is not in line with the national environmental protection concept of energy saving and low carbon. Therefore, the application of LED to public lighting has certain risks.
In addition, after the media broke out again in the past few years, the sequelae of the LED industry continue to show up. I am afraid that the shuffling period of the LED industry will continue until mid-2014. If the LED companies do not see the market environment in time, they may even repeat The photovoltaic industry is wrong.
For a while, the LED light source that has been optimistic about the government and the industry has fallen into a deadlock. At the same time, from another perspective, after the crazy chaos, the industry began to calmly think about the future development direction of LED light sources.
The government is wary of "doing bad things kindly"
A few days ago, the reporter went to Shanghai to investigate the development of the LED light source market. According to people familiar with the matter, LED lighting used to be the “sweet meat†in the eyes of the government in Shanghai. Most of the LED upstream chip companies have been given huge subsidies. However, since this year, the subsidized companies have not achieved any results, the person said that Shanghai began to suppress the development of LED lighting. In 2009, the Yangzhou City Government of Jiangsu Province introduced the MOCVD subsidy policy, which made other local governments in China follow suit. However, as early as last year, Yangzhou suspended the MOCVD subsidy policy, and MOCVD subsidies gradually ceased everywhere. Obviously, if Shanghai disclosed by the insider will start to inhibit the development of LED light sources, then this is most likely a microcosm of the development of LED light sources in the country, and the development plans of LED light sources in various local governments may also gradually return to rationality.
Since the development of LED, policy subsidies have been issued one by one, from upstream equipment to downstream application procurement. However, how many companies are really going for R & D, expanding production, and contributing to the development of the industry, rather than spending it as "pocket money"? If the subsidies are in place, but the development of the enterprise has no effect, what measures should the government take to rescue? Do we need to go through legal procedures? Or does it mean that the people's hard-earned money is lost and can't be investigated? In addition, after the termination of the huge financial subsidy policy, what kind of situation will the subsidized enterprises face? What impact will this have on the industry?
From a coup to a "bamboo basket draws water", government subsidies are understandable, but the path chosen should obviously be rethought, and vigilance evolved into "good intentions to do bad things."
The overall production of LED lights is contrary to the purpose of energy saving?
As we all know, LED lamps only need to consume a small amount of energy to produce the same amount of light as incandescent bulbs, but this is only a small part of what most people know. In March last year, a research report by Carnegie Mellon University pointed out that LED lights can indeed save energy, but the researchers also pointed out that they did not take into account all aspects of the production process. The overall production process of LED lights It may be quite energy consuming, not far from the energy efficiency of general energy saving bulbs. According to foreign media reports, the energy consumption of LED lamps, which are always known for energy saving, is higher than that of ordinary light bulbs in the production and recycling process. Obviously, the "energy saving" function cannot be achieved.
During the visit of the reporter in the past two years, many people in the industry said that the higher the chip requirements, the higher the waste caused in the production process, and the energy consumption is terrible. Assuming that the energy consumption of the entire production process of LED lamps is much greater than the overall energy consumption of incandescent lamps or compact fluorescent lamps, how can the emphasized energy-saving effect of LEDs be achieved?
In addition, the small size and easy control of LED light sources will lead to a diversified design of future lamps and lanterns, rather than a single appearance such as incandescent lamps or compact fluorescent lamps. In this case, it will definitely consume more energy and materials. To achieve the needs of diversified design, from the perspective of life, LED light sources in the future will definitely bring a more colorful visual experience to the world, but industry insiders also say that it is unquestionable to pursue a better life experience, but is it true Need to spend more resources to achieve this goal has yet to be considered, after all, LED light source has always been the most emphasized "energy-saving and environmental protection" effect.
In summary, whether the overall production of LED lights is contrary to the purpose of energy conservation, and more authoritative research experts, production enterprises and related institutions are required to jointly investigate and analyze the total energy consumed by each link in the production process, for uninformed industry professionals Even mass consumers answer questions.
