On the 20th, many domestic experts and scholars gathered in Xiaolan Town to make suggestions for the development of Zhongshan LED industry. Among them, experts have proposed that the development of the LED industry should be gradual and gradually shift from auxiliary lighting to other lighting with high standards.
â— LED industry needs to develop to high-end
Ren Yuanhui, deputy director of the China Lighting Association and the National Lighting Lighting Standards Technical Committee, said that the LED industry is still in its infancy, and the technical level is still low. There are over 10,000 enterprises in the country that currently produce LED products on a large scale. Most of the products of the company are of low quality and cannot meet the standards of energy saving and lighting.
"Enterprises should now focus on scientific research and supporting construction to avoid blindly expanding production." Ren Yuanhui said that high-end technology is what LED companies need to master at present.
â—Auxiliary lighting is the starting point of industrial development
The LED industry has a huge roots. Where should companies start? Ren Yuanhui said that instead of competing with mainstream fluorescent lamps, it is better to adopt the strategy of “urban encircling the cityâ€, starting with auxiliary lamps and then gradually turning to other lighting fields.
Ren Yuanhui said that the fluorescent lamps currently in use have a history of 72 years of development. The technology in all aspects has been perfected, and the supporting industries are also very complete. The dominant position in the market is difficult to shake. LED lamps have not yet met with them in terms of technology and application. Therefore, the slogan of all kinds of indoor LED lamps proposed by many companies is worth considering.
In fact, the LED lamp itself has many advantages. For example, the LED lamp has a luminous angle of 120-130 degrees. When it is made into a downlight, it has the advantage that the fluorescent lamp is incomparable. At the same time, the illumination and energy saving are not comparable to those of the fluorescent lamp. In this auxiliary and functional spotlight field, it is also the weak link of fluorescent lamps, which can be a breakthrough point. After occupying these auxiliary lighting fields, with the development of technology and turning to other types of lighting, enterprises can realize reasonable expansion of enterprises, and gradually enter the market and replace the fluorescent lamp market.
 â—In 2012, LED production value is expected to increase by 9 times
Experts put forward proposals for the steady development of “hot and coldâ€, which was widely recognized by the government departments and business leaders present. Dong Cai, deputy director of the Municipal Science and Technology Bureau, believes that the experts' suggestions have pointed out the direction for the LED-related industries in the initial stage, and the facts show the current status of the LED industry, which is conducive to enterprises to better choose their own development path.
"The new energy base based on LED-related industries will achieve 100 billion output value around 2012, and the LED-related industry will become a new economic growth point with its core position." According to Dong Cai, in 2009, Zhongshan LED-related industries have achieved total With an output value of about 6.5 billion yuan, it is the foundation and core of Zhongshan's new energy base. From now until 2012, Zhongshan will have plans to establish LED-related industries, wind energy industry and solar energy industry as the three core new energy bases. It is estimated that the total output value of the base will reach 100 billion by 2012, among which LED-related industries The output value accounts for about 50%, and the total output value exceeds 50 billion yuan, which is 9 times.
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.
