Chinese Government promotes the policy that green technology popularizes to make the desired effect, the generating capacity of the wind-force and installed capacity of photovoltaic are heightened, is driving the rise of the green energy supplier of new generation.
Under the energetical support of government, wind power generation and market of photovoltaic solar energy of China reach the new height in 2009. The wind-powered electricity and photovoltaic are two Fructus Rhamni parvifoliae color industry of China. All in all, China green take action and have an effect recently, it is after the government makes a promise at Denmark Copenhagen World Conference on climate of December of 2009. At this meeting, Chinese Government promised, would cut down carbon discharge amount of China by about 45% on the basis of 2005 in 2020.
In order to realize this goal, China suggests liking to reduce the reliance on the coal, develop its new developing renewable energy industry at the ... Read more

Kindness intelligent Pu’s semiconductor (NXP Semiconductors) Claim to put out MPT612, it is only to using the solar energy photovoltaic (PV) The application of the battery or fuel cell offers some tracing (MPPT) of maximum power Low power consumption integrated circuit. MPT612 IC is being adopted in MPPT algorithm of the application for patent, when can be used solar energy battery charge control device, distributed MPPT and miniature inverter,etc. and employed extensively, realize 98% of the quantity with high capacity and efficiency is drawn.
Kindness MPT612 of Pu can dispose and used in various solar energy direct-current charging control devices to use MPPT easily intelligently, such as the portable equipment and applied battery charger of the family; Railway and traffic signal; Street, garden and lane light. MPT612 is very suitable for not storing electronic motors such as water pump and electric fan,etc. too.
Kindness Pu flexible MPT612 solution adopt low po... Read more
“Grasp key technology and enterprise made such as epitaxial wafer and chip, has occupied 70% profit of the whole link chain. ” On August 26, the semiconductor of Chinese lighting electric apparatus association lighted professional committee’s director Tang GuoQing to sketch the contours of a profit atlas of LED industry to the reporter, “even if in residual 30% profit, 20% have been got by chip package enterprises, only leave 10% for terminal application links ” .
But terminal application is most China LED enterprise’s agglomerative fields.
According to LED industry research institution - -The statistical findings of LEDinside, up to the end of 2009, there are more than 1300 enterprises engaged in LED midstream and downstream business in the triangular area of pearl alone, among them there is over 900 home in Shenzhen. Over 90% of the native LED enterprises should fight in these 10% of the profits with a weapon and fight ... Read more
The core is pointed out: The expert thinks, under the circumstances that national low-carbon policy, government’s financial subsidy, achievements of development area are led, the intersection of China and LED run firstly before leaving, get on horse street lamps, Landscape Lamps of exterior illumination on a large scale, in fact this direction is wrong.
