The Need of LED Backlight Technology
Seven Advantages of LED Backlight Technology
The technology of led backlight has become the mainstream, and led backlight is recognized for its no mercury, low energy consumption, excellent color and long working life. Firstly, the expressive force of backlight color is stronger than CCFL backlight, which can make up the lacking of display color for liquid-crystal technology. Secondly, wholesale LED lights can be used for more than 27 years, even it has been used for 10 years, which prolong the using life of liquid crystal display television, and it can achieve great advance in technology. Thirdly, it is easy to achieve the control of led power, therefore, user can easily adjust the brightness of equipment to the best condition. Fourthly, traditional CCFL tube owns low spangle frequency which will make pictures jump in showing dynamic scene. Led backlight can adjust light frequency flexibly, and its frequency is higher than CCFL. Fifthly, because red, green and blue light flash independently, it is easy to control its display color characteristics
Shortages of LED Backlight
As we know, led backlight is in 10.4 inch, even less than 15 inch, for led use direct current, and it is easy to drive without transverter, and the efficiency can be improved greatly. White led is not really white color, but in fact, it is blue led which is added yellow phosphorus to produce white light. There is gap between green parts and red parts in spectral curve. No matter the size of screen, most screens need more than one led to achieve the brightness, and it is difficult to make the brightness well-distributed. Especially when the problem of led ageing becomes more seriously, then efficiency of power should be considered carefully.
Conclusion
Modern world requires portable products which needs the reduction of cost, weight and consumption on one hand, while on the other hand the multimedia function needs to be added. In addition, the excellent appearance should also be put in the first place. And we should try our best to combine the functions and appearance. Led industry definitely will become leading industry in our life for it plays an important role in our daily life.

Promotion of the Positive Development of LED Industry
Existing Problems of LED Industry<br>
<br>
The key issue of the current domestic LED industry is the lack of core technology, the demand side is not effectively opened, and the policy should be more to be forceful. These can all be solved through facing their own shortcomings and efforts. But in terms of the reality LED lighting products, such as high-power and high-brightness LED chip products are still dominated by foreignled light manufacturer. The one hand, the domestic LED upstream companies have to be actively involved in this "cake" and make efforts to increase the upgrading skills; On the other hand, the government's industrial policy should change from the project subsidies mode before to the level of technological encouragement. Multi-market allows the industry to get into the orderly development under the guidance of the government.<br>
<br>
Current Situation of LED Industry<br>
<br>
Led industry is a typical industry which grows rapidly on the background of transformation and upgrading in the last two years. Objectively, the current downturn of industry is the result of the combined effects of many reasons, such as the impact of the economic environment, the concentrated release of industry capacity, the decline in the market such as the market of inground led light and the terminal growth in demand is lower than expected resulting in the long corporate investment recovery period and the tense funds chain. The rapid capacity expansion cannot be supported only by the market, and it is the boost of policies and funding at a large extent. Similar to the photovoltaic industry, LED industry model is also put in generous investment upfront, purchase off-the-shelf equipment from abroad with basic team and technology at the same time, and then you can become an LED enterprise. The "low threshold" entry in this industry is the important reason for local governments and enterprises of all types to invest.But in front of the market, companies eventually have to face the reality of the problems of cost, technology, human resources, patents, market demand, and the follow-on funding. The chaotic period of industry expansion doomed to face the dilemma. From the positive point of view, this is not a bad thing to take into account the opportunities and risks of the market, and an industry is able to survive.<br>
<br>
Industry Consolidation of LED Industry<br>
<br>
Despite the promising stage, industry consolidation is still inevitable. The thriving and chaos exist together in LED industry, only after a deep integration can make it enter the orderly and healthy development track. Insiders pointed out that, despite the industry is experiencing growing pains, for prominent companies who have brands, channels, talent, technology and operations management capabilities, it means more opportunity, these enterprises can develop in large scale.<br>

Maintenance and Selection of Outdoor Furniture
Importance of Outdoor Furniture
With the increasing of outdoor travel and widening of people's living room, people tend to leisure life in countryside, therefore, outdoor furniture will become more and more popular, and more and more garden furniture manufacturerare designed and produced. Furthermore, antiseptic treatment plays an extremely important role in outdoor furniture. In general, the surface of wood is printed with china wood oil, sprayed with preservative.
Selection of Outdoor Furniture
The material of outdoor furniture plays an extremely important role in the maintenance in days to come. Therefore, we should not only judge it by appearance but some important factors. The first one is weather and climate. You had better take weather into account, because the rain and sun will affect the using of outdoor furniture. The direct sunlight will make the furniture crack, while the metal material will heat under the sunlight, which will make it uncomfortable to use. What's more, if you live in the places with frequent tropical storm, severe convection or near the sea, the sudden wind may throw mesh outdoor furniture and plastic furniture. Secondly, leave some space around furniture. It is different from house furniture, there is no special function for outdoor furniture, and hence tables and chairs are not needed. In addition, appropriate furniture should be matched according to the size of space. Thirdly, deciding style and material depends on position. Is there sunshade in your outdoor activity area? Is the furniture put in soft lawn or hard floor? Keep in minds that do not use the furniture with cork framework on the lawn, because soft wood absorb water causing the damage of framework, so we should choose plastic and steel framework. And sunshade is needed to protect our skin from damaging by direct sunlight. Fourthly, material is more important than appearance, for it decides the condition of maintenance in the future.
Basic Common Sense of Maintenance
Aluminum and resin are easy to clean, and wicker or wooden furniture should be maintained in regular time, and it can be used in outdoor in a long time. You should pay attention to the sharp materials and cigarette end which will break the rattan. The other series is wooden leisure desk and chair. Place them on the stable ground or lawn in case of the shake. Usage of furniture should avoid long time exposure and rain, and we should cover the outdoor furniture by furniture coverings or other coverings. Or it will age at high speed and its painting will fall down. It is recommended to maintain it every 3-6 months.

Different Types of LED Lights
The Development of LED Lights
In recently, LED lights have come into thousands of households, however LED lighting market at the present stage is not mature enough. Especially the market of led spot lights China is not mature. Different manufacturers have different standards toward LED Lights. And no national LED lighting standard has been published, so it should also limit the healthy development of LED lighting market.
Large Power Chip LED
There are many types of LED lights. The first type is made of large power chip LED by LED energy-saving lights. The power generally adopts constant current circuit, which has a constant current, such as 5W LED, usually adopts 5 1 watt LED chip, 300mA series, with constant current source power supply, wide voltage power supply, so that the power fluctuations. The luminous flux to maintain a constant luminance with 5 patch of LED welding on aluminum substrate, and the aluminum plate combined on the radiator, the use of heat can be quickly dispersed to ensure LED chip temperature of less than LED allowable junction temperature, so as to ensure the LED energy-saving lights in the real life. Some manufacturers by virtue of its good quality, producing recessed led ceiling lights, become led underwater light suppliers. This type of LED lights is in high prices, good quality, but also the development direction of LED energy saving lights. It is a straw hat type small LED efficient light made from LED energy-saving lights, power supply using a resistance-capacity pressure reducing circuit.
3528 or 5050 Patch Power LED
Second category is the 5050 patch, from 3528 or 5050 patch in the power LED made from LED energy-saving lights, power supply is also generally use a resistance-capacity pressure reducing circuit. Some manufacturers use a constant current circuit compared with straw hat type LED, patch LED cooling slightly better as it has a heat conducting substrate. In conjunction with aluminum substrate, there can be part of heat. But as a result of or ignored LED heat, a lot of power chip LED lights have no radiator, they still use plastic shell. By means of resistance and capacitance voltage to have low power, due to voltage instability, current fluctuations, brightness is also fluctuating. A lot of LED lawn Lights are the same as these types. The third type is Straw hat type LED used indicator LED's form of encapsulation, epoxy resin package, makes the LED chip to heat dissipation. A lot of white LED, after being used for a period of time, the color temperature will become higher and then become the color of bluish and dim. There are also manufacturers committed to the development of low light straw hat type LED, but with no any change in encapsulated form, the light still did not change much. This type of LED energy-saving lights products is a transitional product whose price is low, and the quality is also poorer.
