LED lighting indoor lighting energy saving at least 75%

According to the survey: LED lighting indoor lighting can make savings of at least 75%, LED lighting became public business and the user’s choice.

LED lighting is the use of high-brightness white LED light source to emit light, and its high luminous efficiency, low power consumption, long life, easy to control, maintenance and safety and environmental protection features, making it a new generation can replace traditional light sources star product. Especially its outstanding performance in energy efficiency, it is amazing: It is understood that it is only the energy consumption of traditional incandescent lamp 1/10, energy saving lamp 1/4. This means that if you replaced all traditional lighting LED lighting, the annual electricity savings of 60% -75%. Some LED companies started from LED lighting design aspects, experts said, “If the country the traditional lighting sources, all replaced with LED lights, can save a year of electricity is 2.5 total power generation of Three Gorges Dam.”
LED energy-saving is also reflected in its higher luminous efficiency ratio. Traditional incandescent at work, there is 80-90% of the energy is converted into heat, only 10% of the energy is converted to light energy. The LED lights at work, LED electro-optical conversion efficiency of 30% to 50%, which is three to five times that of traditional incandescent. That is to say, to achieve the same brightness effects, LED 60% energy than traditional incandescent or more. From the brightness speaking, LED and incandescent same in the case of energy, LED lamp brightness higher.

In addition to energy savings, this new type of lighting is also more environmentally friendly. “A waste of traditional energy-saving lamps, with an average of about 0.5 milligrams of mercury, enough to contaminate 180 tons water and the surrounding soil, but LED lights have no problems in this regard.” Said Ren see. In addition, LED lights also has a long life, cost-effective, convenient transportation and installation characteristics, by virtue of these advantages, LED lighting has become the urban landscape lighting of the “main force”, meanwhile, will be more and more integrated into the lives of ordinary people , the development prospects were bright.
Experts said: generally optimistic about the current LED lights, for example, in the next 10 years, is expected to further enhance the brightness can be 20 times, while the cost will be reduced to the existing 1/10. “While industry experts predict that as incandescent eliminated accelerated worldwide LED lights will usher in a favorable investment market is expected in 2015 China LED lighting output value will reach 500 billion yuan, accounting for 30% of the mainland than the general lighting market .

2013 will usher in the LED lighting industry boom

“With the LED backlight, lighting market demand, chip, package, and application vendors orders full, in 2013 the market gradually opened since the second quarter, the LED industry will usher in the next 7-8 years period of prosperity.”The led company Guangzhou Guangya Messe Frankfurt Exhibition Director Dr. Pan Wenbo at the 18th Guangzhou International Lighting Exhibition news conference, said, “the next eight years, there will be about 80% of lighting products LED products to replace the entire Chinese market demand growth is more impressive.

As technology continues to mature and product prices, the market will break out in 2013, and will usher in a “replace” period.
February 6 this year, ministries jointly issued the “semiconductor lighting energy industry planning,” pointed out that by 2020 the global lighting market will more than 150 billion U.S. dollars, LED lighting market is expected to reach 75 billion U.S. dollars, accounting for the global lighting market share of 50%. As the market continues to expand, when the LED “replacement” of the past, the companies how to survive? “When the real LED lighting products comes, at least half of the companies will go bankrupt, the fight is finally enterprise business model will not only reflect light LED light function is to provide more added value.”
Low trade barriers, high government subsidies and preferential tax policies, many companies come crush, low excess capacity situation is more serious. To be able to fierce “battle” to win the victory, the enterprise will “tentacles” reach out to the segments. In the home market, LED products, price issue has not entered the field of the “obstacles”, LED has gradually infiltrated the domestic industry, the future will be towards energy conservation, aesthetics and other aspects of development. The current development momentum strong field of electronic business, has also been testing the water companies. LED enterprises to enter the field of electronic business, firstly the need to strengthen the brand culture guide, build corporate brand; Secondly, for the online and offline products need to be differentiated development, the establishment of a good profit-sharing mechanism. “Electricity supplier has a great feature is the big data, the data can be analyzed using the user’s buying psychology, buying behavior, etc. For large data utilization, companies need a clear positioning, market segments breakthrough vertical electric providers also refine market in a process. “

High quality LED tube are inevitable trend of development

　　Slow growth in recent years, LED lighting, but beginning in 2012, as governments continue to pursue policies to ban incandescent, LED lighting industry outlook established. Topology view, after the incandescent period has come from the outdoor lighting applications market development priorities, commercial lighting, industrial lighting, automotive lighting subordination, and finally penetrate into the domestic market in the next four years for the LED lighting market last key layout period.

professional led lighting in South America market — quality led tube

Experts pointed out that because the LED light source with a high color rendering, high plasticity and other characteristics, and is currently in the outdoor architectural lighting and outdoor display screen penetration has reached 90%, plus subsidies lights, LED outdoor lighting is also ahead of the growth rate other types of lighting.

Unlike the rapid development of outdoor lighting, LED home lighting Topology think the biggest obstacle, expensive, lack of brightness will be the biggest factor in development of the market disruption, so the overall LED lighting penetration rate of 20% will be the first face bottlenecks, once after the break will have explosive growth.
However, experts warn, because LED lighting products for up to 20,000 hours life, about 8 to 10 years before they need to be replaced, so when the LED lighting penetration rate of 40%, the market will once again face the replacement cycle is too long, and makes weak demand growth dilemma, estimated to be in 2016 will gradually enter the market after maturity.
LED lighting fixture is undoubtedly the future direction of development, but how to reduce the cost of LED lamps LED whether the popularity of the market has become an important part. In fact, at this time there a few years, LED lighting prices are at an annual rate of 35% -50% down, I believe that in the near time, LED lamps prices will drop to every household acceptable range, that time is LED lighting era has arrived.

Energy-saving lamps and LED tube set

Have a short life because incandescent, energy consumption, coupled with the rising cost of energy for many reasons, incandescent launch stage of history is an inevitable thing, then replace it with the energy-saving lamps and LED lights, that could do better? Before that the true successors of incandescent? we might look, energy-saving lamps and LED tube set.

One: the status of energy-saving lamps
In recent years, our country has been through a lot of manpower, material and financial resources to promote the use of energy-saving lamps. With the phase-out of incandescent lamps is ‘Proton’ out of the market for energy-saving lamps brings a huge space for development, more and more companies have introduced energy-saving lamps lighting products, to seize the remaining market.

Currently, energy-saving lamps are the most widely used everyday consumers incandescent replacement product. Its efficiency is more than five times of incandescent bulbs, the average life of about 8000 hours, mature technology, and lighting, lamps matching, and is a simple and relatively low-cost replacement option. However, energy saving and environmental protection should complement each other in this, but in the energy-saving lamp body, but both went to the opposite, the problem is bound mercury will eventually be replaced with energy-saving lamps fate: a common energy-saving lamps average mercury content 0.5 mg, The mercury dipped underground about 180 tons of water may cause pollution. If the improper disposal of waste energy-saving lamps, is likely to become “eco-killer”, and waste energy-saving lamps have also been mishandled ‘good years’, and even today is still no appropriate policies and measures introduced.
Two:LED tube set
Longer life LED light source, high efficiency, energy saving, environmental protection and other “theoretical advantage” has passed the test of practice, LED light source of the performance parameters have not always used to say, “improving”, but “further improvement” LED industry’s overall development prospects are generally good.

With the phasing out of incandescent and state subsidies for energy-saving lighting products, LED lighting market has been accelerating. Even in 2012 the industry hopes to popularize the first year of LED interior lighting, LED is gradually tentacles deep into the home lighting market. But now LED lighting products, price issue is still hindered LED home lighting market inroads into the most important factor. In terms of price, the market is 1.2 m long, 21 watt LED lamp normal retail price of 200 yuan, while the same length and wattage of traditional fluorescent tubes basic price less than $ 10; incandescent replacement cost, LED bulbs with the traditional energy-saving lamps in normal circumstances, there are at least eight times higher than the price difference. This price gap is naturally LED lighting into the home environment, the biggest obstacle. Many dealers also said lamps, LED home lighting is still in the promotion phase, more consumers still tend to buy relatively low price energy-saving lamps; in the home market, energy-saving lamps LED lighting products remains the biggest rival, And it is always home lighting energy-saving lamps areas of expertise.

LED tube set fixture is undoubtedly the future direction of development, but how to reduce the cost of LED lamps LED whether the popularity of the market has become an important part. In fact, at this time there a few years, LED lighting prices are at an annual rate of 35% -50% down, I believe that in the near time, LED lamps prices will drop to every household acceptable range, that time is LED lighting era has arrived.

Mainstream LED lights for lighting trends

LED is a low-voltage semiconductor and punctuate cold led light with longer life, high efficiency, energy saving, environmental protection and other “theoretical advantage”, which has passed the test of practice. The performance parameters of LED light source are not used to say “improving” or “further improvement “, The overall development prospects in LED industry’s were generally optimistic.
With the phasing out of incandescent lamps and the energy-saving lighting products, and services, led lighting market has been accelerating. LED is gradually entering into the home lighting market, but the price issue of LED lighting industry product is still hindered in LED home lighting market, which is the most important factor. In terms of price, the market retail price for 1.2 m long, 21 watt led lamp is 200 yuan, while the same length and wattage of traditional fluorescent tubes’ price is less than $ 10; In normal circumstances, the price difference between incandescent replacement cost and LED bulbs with the traditional energy-saving lamps are at least eight times higher. This price gap is naturally the biggest obstacle for LED lighting into the home environment. Many dealers also said lamps, LED home lighting is still in the promotion phase, more consumers still tend to buy relatively low price energy-saving lamps; in the home market, energy-saving lamps is the biggest rival for LED lighting products, And it is always a new areas of expertise for home lighting energy-saving lamps.

LED lighting fixture is undoubtedly the future direction of development. It is worth pondering, and with policy support. LED industry maintains the doubled growth rate for many years, but they did not start the LED lighting civilian market. In addition to higher prices, instability quality, not high cost is the main reason. In fact, at this time of few years, LED lighting prices are at an annual rate of 35% -50% down, I believe that in the near future, LED lighting prices will drop to a reasonable range that every household can be acceptable, at that time, it is the LED lighting era.
LED lights for energy-saving lamps prevailing trend
In the wave of restructuring traditional lighting to LED lighting, some manufacturers in the market competition are inevitably eliminated, but some steady development based on technological, after emerging industries must withstand any test of the market to mature, this is the process for any kind of conventional light sources, traditional lighting and LED lighting are representative of different stages of development. LED industry’s rapid development, the government’s promotion efforts, All this does not mean that LED lighting is the traditional nemesis.
Insiders recently put forward in the micro-Bo: “Do not be seen with the traditional lighting and LED are simpler alternative relationship, not separated, if do so, it would ruin the LED lighting industry. LED lighting is the traditional relationship between inheritance and development, we should use this way of thinking starting from the LED light source combined flexible features to find the most suitable arena to shine. Only from the “alternative” perspective, LED light and lighting is naive and superficial performance. “

How to apply high-quality LED lighting

In the early 1990s, LED for cars and trucks brake lights. Some LED design soon emerged inconsistencies performance indicators, and quickly burned down, the reason may be due to the LED quality problems, perhaps the design of the product itself is entirely the problem. Until recently, in respect traffic lights, when the LED light source to become more appropriate, this phenomenon was only seriously. Design covered with a diameter of 8 inches or LED 12-inch PCB companies must choose the LED and improve the design and other aspects to consider environmental and application needs.

Any of the above circumstances, if the pressure test or accelerated life cycle tests have been done, it can be considered high-quality LED or LED assembly is qualified, it can be applied to a longer life and higher reliability occasions it.
Not every application requires high quality LED assembly technology. If the LED assembly does not meet the requirements of harsh environments, the application will not necessarily a larger security risk, or, if the final product is not very high maintenance costs, the use of some poor assembly techniques may be more appropriate.
The most fundamental point is the LED must be able to afford. Therefore, within the limits of the cost requirements, we must consider the level of vendor product packaging, assembly and testing of design experience and other factors. Meet the application and market demand is designed to serve the end user the most effective means. If the application requires high-end solution, then the chip vendor selection, design experience, and testing are all factors to be considered. If you do not consider the high-end product sales price, you should carefully consider the difference between good and bad LED and other relevant factors. Have the ability to classify the packaging level LED suppliers, and the ability to carry out reliability, accelerated life cycle testing vendors be able to conduct long-term cooperation, which helps manufacturers to adopt a more reliable LED develop high-end products.

How to ensure high-quality LED lighting equipment

Most designers think all LED lighting product quality is the same. However, LED manufacturers and suppliers many Asian manufacturers to global supply cost of the LED. Surprisingly, in these manufacturers, only a few can produce high-quality LED. For indicative only as a simple application, low-quality LED is sufficient to meet the requirements. However, in many of the requirements consistency, reliability, solid-state lighting and other areas of instruction or must use high-quality LED, especially in harsh environments, such as highways, military / aerospace, and industrial applications.
In the New York subway station environment, security requirements are very demanding, LED must meet the quality requirements of fundamental factors.
Distinguish between high and low quality LED factor is what? How to tell the difference between two kinds of LED? In fact, the selection of high quality LED chip can begin until assembly is complete, during which there are many factors to consider. Tier-One LED manufacturing company to produce good, consistent indicators wafer is manufactured from high-quality LED material humble beginnings, in turn, can produce excellent chip. LED performance in determining the conditions of all, the wafer used in the production process is a very important chemical material factor.
A 2 in. wafers can be cut out of more than 6000 LED chips, there is only the individual and the overall chip performance indicators are different. And an excellent chip makers manufacture chips in color, brightness, and other aspects of the voltage drop difference is very small. When the LED chip package is complete, the performance of many of their great differences may exist, such as the viewing angle. In addition, the impact of packaging materials is quite large, for example, than the epoxy silicone performance.
Classification ability
LED manufacturers excellent quality can be manufactured not only of the chip, and also has a color based on the LED luminance, voltage drop and angle to classify the different packaging capabilities. High quality LED vendors to provide customers with consistent product performance characteristics, while lower-quality LED suppliers can only offer similar to the “mixed” of the LED.
For the high-end, quality demanding applications, such as runway edge lights, must meet FAA specifications color and brightness level, to ensure performance and safety, LED packaging consistency and it was strictly limited. Packing LED is used in less demanding applications will lead to premature failure of a series of non-conformance issues, is likely to lead to a major accident. To avoid equipment downtime and ensure that the design requirements of the LED with a reliable operating characteristics, and the strict quality requirements of high-end applications avoid the use of “mixed” product is very important.

Products supporting capacity
In addition to discrete LED, LED assembly and power supply for its performance, brightness and color indicators have a very significant impact. The ambient temperature, the operating current, the circuit structure, so the voltage spikes and environmental factors can influence the performance of LED, proper circuit design and assembly is to protect the LED and ensure the performance of the key. LED manufacturers can use a variety of techniques and different materials to design the circuit structure and assembly, in most cases, LED assembly difference in the experience of the level of the same application will cause the LED in the overall performance and reliability differences.
With the rapid growth in demand for LED, serve the global market manufacturers and assembly plants also increased rapidly. Unfortunately, the surge in support for manufacturers not only a large number of low-quality LED, their packaging and LED design engineers relative lack of experience. Therefore, in addition to the existing experience and accurate screening through LED suppliers outside, OEM manufacturers must also examine their circuit design and assembly techniques to ensure that it meets design specifications, and design provides adequate cooling capacity, because causes the LED failure and performance The main factor is inconsistent overheating.
To ensure that it meets the design requirements, OEM must detect the LED assembly and circuit structure.

Advantages and disadvantages of LED lamps

LED lamps outstanding advantages are:
1, energy saving, LED luminous light efficiency, incandescent light efficiency is 15-20LM / W, LED lamps with high luminous efficiency can reach 60-100LM / W; That traditional 60W incandescent lamp with a 10W or so LED lamps can be replaced; LED fluorescent lamps are also compared with about 20% energy saving.
2, environmental protection, LED is a semiconductor device, do not contain mercury and other heavy metals materials; traditional energy-saving lamp manufacturing process and the use of waste mercury pollution, LED lighting energy saving lamp manufacturing process and use of process does not produce mercury pollution.

3, long life, LED theoretical life of 100,000 hours, and is currently better quality life of 25,000 hours LED lamp warranty, incandescent lamp life of 1,000 hours, the fluorescent lifetime is more than 7000 hours.
4, high color rendering index, which is the color reproduction and high.
5, LED is a DC-driven, more suitable for solar lamps, solar panel life of 10-15 years, with a fairly long life of the LED general lighting maintenance costs will come down a lot; avoid the frequent replacement of light caused by maintenance costs.
Disadvantages of LED lamps
1 high cost, the current LED lighting gradually into the field of commercial lighting, LED lamps for general lighting manufacturing cost reasons in the field of large-scale application needs time.
2 LED constant current drive power required, the power of life affect the overall lamp life is one, if the LED power supply replacement is more convenient, you can overcome the power of the overall impact of lamp life.
