LED lighting has become the focus of many exhibitors in the display of the main application results of the 12th Shenzhen High-Tech Fair energy conservation and environmental protection industry. BYD, Dongguan Qinshang Optoelectronics, Shenzhen Xuguang Lighting and other Chinese mainland led lighting companies have launched their own LED lighting products.
It is reported that since the launch of the semiconductor lighting project in 2003, thanks to the decline in product prices brought about by industrial policies and technological breakthroughs, the LED lighting industry in mainland China has grown rapidly, initially forming upstream materials, midstream chips, downstream device packaging and applications. R&D and industrial systems. By the end of 2009, more than 3,000 companies had entered the LED industry, including more than 40 upstream epitaxial and chip manufacturers, more than 1,000 midstream packaging companies and 2,000 downstream application products manufacturers. In 2009, the output of LED lighting increased from 94 billion in 2008 to 106.5 billion, and the industrial scale increased to 82.7 billion yuan (RMB, the same below), an increase of nearly 20%.
Shenzhen Jufei Optoelectronics said that the price of indoor LED lighting has dropped from 200 yuan per year last year to 160-170 yuan, which has become the main driving force for the growth of LED lamps.
Although mainland China has become the world's largest LED street lamp market, the popularity of LED street lamps still takes time. The reasons are as follows: First, under the energy-saving and emission reduction policies, LEDs are mostly used in street lighting and landscape lighting projects. The market share of the entire LED lighting market in the Chinese mainland lighting market is not high? 莶t solution, no one company's market share exceeds 2%, and the entire LED industry in the mainland lighting market market share of less than 10%.
Secondly, the public can not accept the current high price of LED lighting, so LED lighting is limited to large factories and supermarkets, and can not really enter the family, which greatly affects the promotion and development of the LED market.
In addition, the quality of LED products is uneven, the heat dissipation technology is not perfect, and the long service life of the power supply also affects the acceptance of consumers and restricts the development of the entire industry.
Therefore, if mainland China wants to become a conqueror in the global LED street lamp market, it is urgent to improve the current industrial situation.
The AC power meters are applicable to the measurement of single-phase or three-phase
voltage and current parameters of distribution system. The transformation ratio of this series of meters is programmable. They supports digital input, relay output, analog output and communication functions. They provide a variety of different installation sizes and can directly replace the analog pointer ammeter.
