A drive circuit as a whole life, especially in the key devices such as capacitor life at high temperatures directly affect the power of life;

2.LED drive to challenge the higher conversion efficiency, especially in the drive of high power LED, because all is not as light output power as heat dissipation, the power conversion efficiency is too low, the impact of the LED energy-saving effect play;

(3) major light is high efficiency LED dimming, while ensuring constant high and low brightness, color characteristics;

Lower costs, less power (1-5W) applications, the proportion of constant current drive power cost has been nearly one-third of the cost of the light source has been close to a certain extent, affected the marketing.

       With the development of the domestic LED industry, the concern of the national policy level, the LED industry gradually increased in the country "to stimulate domestic demand and promote consumption" policy driven infrastructure projects were launched, the gradual recognition of the market for LED products, I believe that LED share in the domestic lighting market will be growing LED industry in the 2011 market outlook will be more extensive.
 

According to the relevant bodies 2011-2015 European lighting market report shows that traditional lighting manufacturers in Europe, although more than

In recent years, with the cause of the rapid development of domestic construction, sand mining can not meet people\\ s development and construction of the required amount of sand, building sand the amount of a sharp rise, but the collection of natural sand by nature river washed sand limit the growth of river sand for the safety of the normal flow of the river and the river has caused some safety hazards. For the safety of the river, across the country have issued a ban on logging to make provisions can sand mining in some time, and the amount of sand mining has been limited. The development of the building resulting in a sharp rise in the amount of sand, so that the sand price began to rise year after year, but the lack of natural sand resulted We must find a good way to solve the contradiction between the gravel shortage and building production. Market demand, and the contradiction between supply and demand, artificial sand.

Artificial sand, also known as the mechanism of sand, rocks and river pebbles from the river digging through the impact crusher (also called sand making machine) processing into the sand used for construction. After the 1990s, the province has been large-scale use of the Sand, and to develop the relevant local standards, Yunnan, Beijing has also introduced a mechanism sand relevant standards and the use of procedures. One after another, Beijing, Chongqing, Hunan and other places have sand production line. Can be said that, as the construction of the basic materials such as concrete, mortar sand, sand application is successful is an indisputable fact, a large number of engineering practice (including the remarkable Three Gorges water conservancy) has been fully proved, the possibility and necessity of the Sand .

The inevitable dry production line

Artificial sand by definition, is the use of machinery and equipment artificial sand stone in the sand making machine inside a stone at the stone, the stone blacksmith such a process, the stone turned into sand. Artificial sand particle surface roughness, the combination of multi-angular, aggregate and cement, aggregate, mechanical bite force than artificial sand concrete with natural sand concrete strength. But in the process of stone, due to fierce collision, and the stone itself containing soil amount, so make artificial sand inside a certain amount of powder and clay powder. The presence of mud powder will seriously affect the gradation of the sand. The presence of the powder can make up the gap caused by the artificial sand in concrete, water demand, the mobility of defects and poor. In order to solve the problem of artificial sand with the amount of powder to learn the principle of river sand to create sand washing machine, sand washing machine of washing to get rid of the sand inside the mud powder, so that the artificial sand to reach the sand used in construction standards, this method is called the wet process production lines.

Artificial sand appears, are mainly concentrated in the river or water-rich, sand washing machine, washing powder wash, inside the artificial sand so that sand production lines around the abundant water resources, Otherwise, manufactured sand to reach the construction sand standards, it\\ s still waste a bunch of.

In recent years, studies have found that artificial sand inside the powder in the sand inside and reasonable in accordance with a certain proportion of presence can improve the concrete strength and workability. And engineering geologists Mr. Chen Jialong \"reasonable use of the powder in the artificial sand\" the article clearly stated the importance of the powder in artificial sand. But in the wet sand production line in the sand washing machine cleaning sand, mud powder also powder sand washed. During the washing when wet production line will not only wash away the particles of 75 microns or less, but also wash away, including the 150 micron, 300 micron, or even 600 microns. So that the advantages of the artificial sand will be wet production line cover. And such traditional ways and means of wet sand by the water resources in the areas of water scarcity, and the cold northern winter, artificial sand is still not universal and implementation, building sand contradiction between supply and demand still exists. The same time, the water-rich region due to the way of wet sand, the hazards of water resources is more serious. Waste water on the one hand, a certain amount of pollution of water resources, and another for the flushing of powder in artificial sand is also a waste of mineral resources, and the powder washed away and destroyed a reasonable grading of the artificial sand, is not conducive to the concrete workability. So in the case of multiple contradictions, we must have a new artificial sand and address the needs of the market to solve environmental pressures.

Do you believe, the color is actually a living: they have the Smart, can make all kinds of space, color affect our mood. However, in most people\\ s living space, pale or warm light, we are generally accustomed to. The new LED lights change color, that is, LED lamps with dimming, color mechanisms can produce the effect of altered space atmosphere.

        LED lights change color by the capacitor buck regulator circuit can make red, green, and blue LED lights, a separate light and three color LED lit, issued in seven different colors of light. Outer bulb must be milky white. In order to better blending, non-transparent materials.

        LED lights change color for the family birthday party, holiday parties, festive New Year to add a festive atmosphere to the festival: it can also be used for entertainment and advertising lamp, etc.. For example, blue light halo off the 6:00 in the morning, fresh and soft, warm yellow, cute pink, light green, applied to the comfortable scene. Romantic lilac people to think of wonderful memories, home or commercial space in accordance with need to match the color of the atmosphere, you do not need to change the interior decoration or lighting.

        However, these lamps have a troublesome shortcomings is to control the color change of the circuit of the cost is high, the life of the drive circuit will be a problem, the industry, there are many kinds of solutions to cope with the expected in 2009 class of applications will be more and more, LED mood lighting market take-off of state in 2010.

See a lot of injuries are also a lot of forklift use of improper lead, the company is now a simple introduction to how to properly use the forklift.
