The low-carbon economy is now the focus of attention. In the long run, sustainable low-carbon and green economy will be the general trend of future world development, which will undoubtedly bring huge opportunities for the development of energy-saving and environmental protection industries such as LED lighting. The emerging LED lighting industry with green and ecological lighting as its core is now accelerating in China. On the one hand, the government is strengthening the implementation of a strong policy to promote this industry; on the other hand, enterprises are also accelerating the layout in this area, and the synergy will obviously help China's LED lighting industry to break through barriers and take a higher step. .
   The continuous development of LED lighting, the market opportunities facing it is very big, China's first batch of national standards for LED lighting was released recently, which will become more of a hot spot in the field of LED lighting. However, at the “5th China LED Industry Theme Summit Forum†jointly organized by Gaogong LED and Tianjin Dongli District Government, many industry experts reminded that companies that want to get involved in this market should realize that there are many LED lighting fields. The challenge.
   Suzhou Najing Liang Bingwen pointed out that the challenges faced by China's LED lighting industry are mainly lack of talents, serious delays in product standard testing and supervision, lack of market transparency, lack of independent intellectual property rights, lack of high-quality capital and investors, and foreign companies investing in the mainland.
   Zong Mingcheng of Philips Global Technology Development Center believes that the challenges facing LED lighting are cost performance issues, improvement of light efficiency, quality of lighting systems, establishment of standard systems, and development of new applications by leveraging LED advantages. Zong Mingcheng pointed out that the standard should minimize the performance requirements, because solid-state lighting technology is developing rapidly.
   Dr. Zhang Xiaofei, a high-tech LED, pointed out that “Ten Cities and Ten Thousands†has made China a testing ground for global LED street lights. The success of “Ten Cities and Ten Thousand Cities†will affect the future direction of China's LED industry. According to a survey by the High-tech LED Industry Research Center, there are still many problems with the current LED street light technology. It is not recommended to launch a large-scale LED street light project.
   The market size is now large enough. If companies that are interested in this industry do not enter, they will miss the opportunity. But if the direction is wrong, it will be a waste of effort to go far. At present, many lighting companies in China have invested huge sums of money for the research and development of LED products, but in the future, not many of these companies are clear.
Fortunately, the first national standards for lighting products announced by the Ministry of Industry and Information Technology have pointed out the direction for the company's product development. High-tech LED analysis, in the broad field of LED lighting, domestic and foreign lighting companies will start a fierce competition, who wins no one is still uncertain, only in the competition to constantly improve themselves, and thus in the market's fierce battle Play a beautiful Wing Chun.

Leakage protector, also known as leakage switch, is a new type of electrical safety device, mainly used for:
(1) Prevent electric shock accidents caused by electrical equipment and electrical circuit leakage;
(2) Preventing single-phase electric shock accidents during electricity use
(3) Timely cut off single-phase grounding faults in the operation of electrical equipment to prevent fire accidents caused by leakage
(4) With the improvement of people's living standards and the continuous increase of household appliances, personal electric shock and fire accidents caused by defects, improper use, and inadequate safety measures of electrical equipment in the process of using electricity have brought undue damage to people's lives and property. The emergence of leakage protectors provides reliable and effective technical means for preventing various accidents, timely cutting off power, and protecting equipment and personal safety.
The leakage protector should meet the following technical requirements
(1) The sensitivity of electric shock protection should be correct and reasonable, and the starting current should generally be within the range of 15-30 milliamperes
(2) The action time of electric shock protection should generally not exceed 0.1 seconds
(3) The protector should be equipped with necessary monitoring equipment to prevent it from losing its protective effect when the operating state changes. For example, for voltage type electric shock protectors, a neutral grounding device should be installed.
