 The wholesale price of green laser pointer is much lower than retail price of green laser pointer .
Under the trend of energy saving needs of the climate conference in Copenhagen in 2009 energy saving again become the focus of global concern, and to people because of rapid industrial development of the environmental pollution has become more in-depth understanding of global development has become the subject of today's . Meanwhile, after the economic crisis, China's rapid economic rebound and continued to expand domestic demand, such as automotive electronic components caused by the revitalization plan to support the policy of nationalization, home appliances, energy subsidies, trade-in, which greatly boosted the automotive electronics, energy-saving appliances, medical electronics, mobile communications industry; and vigorously promote low-carbon economy, continue to emphasize energy conservation, energy demand will continue to enhance products, energy efficient products in the subsidies will also have stimulated the rapid development of , January 2009, inverter air conditioner was officially included in the "energy-saving products in government procurement list", will allow us to air in 2010, ushering the era of high energy efficiency. The cell phone can not be used during the sleeping time because green laser pointer is on.
Thermistor devices have chip miniaturization, high precision, low power consumption, according to the temperature coefficient of resistance can be divided into negative resistance temperature coefficient (NTC) and positive resistance temperature coefficient (PTC) thermistor; the operating temperature range , resistance increased with increasing temperature is the PTC, the traditional TV and monitor applications, mainly in the degaussing circuit; resistance decreases with increasing temperature is the NTC, the temperature sensor on the main application, the accuracy can reach 0.1 ℃, thermal time can be as little as 10s or less. As high technology, thermal electronics market fundamentals for the monopoly of foreign enterprises, German, Japanese companies, the world's total output value of about 60% -80%. NTC temperature sensor as a sensor, accounting for more than 40% of total demand, NTC thermistors based on its excellent price-performance ratio the proportion of components in temperature up to 60% or more. The parameter of green laser pointer can help with the manufacture of green laser pointer .The development of electronic packaging materials, has been showing rapid growth, global market, involving the development, production of high-end liquid epoxy encapsulation materials demand in 2003 reached 700 tons, with sales of $ 350 million; 1500 tons in 2005, sales amount of $ 750,000,000; 8000-10000 tons is expected in 2010. China's market demand in 2003 is about 50-60 tons, 400-500 tons in 2005 up to 1200-1400 tons in 2010.
