LED street lights advantages compared to the traditional

For road lighting lamps, known as street lighting. LED as light source lighting the road, then known as LED lights. LED street light is composed of many high-power white LED connected together via a hybrid approach. In addition to LED module LED street lamps, but also contains the power supply, optical components and cooling devices.

The foundation is intended to illuminate the road for drivers and pedestrians that supply excellent visual conditions, the guidelines they trek to advance transportation power, down nighttime traffic accidents and violations, along with the surrounding environment to help pedestrians to see, the distinction between orientation. Followed by the commencement of the socio-economic level and the continuous advancement of people’s livelihoods, everyone in the night to outdoor recreation, shopping, visits and other activities more and more, also played a distinguished road lighting lucrative livelihoods, economic prosperity, and promoted the role of the city’s image.
In accordance with the concept of lighting, the road can be divided into four categories: automotive-specific road, usually Avenue, Commercial Street and sidewalk. Often speak of the road lighting, represents the vehicle for road lighting. Many of intent on the road lighting, in order to secure a comfortable supply of motor vehicle drivers is the first one of the visual conditions.

LED street lights have a high level of design standards

Road street lighting was first, then successively presents high-pressure mercury lamp, high pressure sodium (HPS) lamps and metal halide lamps, energy efficient lamps, lamp and LED lights. In the current match seasoned road lights source, HPS lamp light-efficient, often reaching 100 ~ 120lm / W, in the current Chinese road lighting throughout the mall (has about 15 million), the high-pressure sodium occupies more than 60% ratio. In some communities and villages on the road lighting foremost is the electronic energy-saving lamps (CFL), accounting for about 20% of the mall road lighting ratio.
In road lighting, high pressure sodium because of its light efficiency can reach 120lm / W for the dominant position. However, along with the continuous progress of LED luminous efficiency, high pressure sodium lamps exclusive location at stake. Currently in use on the secondary roads 150W LED street below, has demonstrated significant energy advantage.
Direct impact on life expectancy street lighting maintenance costs throughout the journey. Current high pressure sodium lamp life expectancy is usually around 20,000 hours, high pressure sodium lighting road use life expectancy of only about 5000 hours, while the power LED’s life expectancy is usually up to 5 ~ 70,000 hours.

How to distinguish between LED and LCD

In fact, LCD always on, just put on a new layer vest, it becomes a LED. But with LCD and LED is the difference between, LED has a great advantage over LCD.
LCD = Liquid Crystal Display, LCD displays, LCD is structured on two parallel glass sideways placing the liquid crystal, two pieces of glass center has many straight and level of fine wires, or to manipulate the rod through the energized crystal molecular changes direction of the light reflecting occurred screen.

How to distinguish between LED and LCD
LED = Light Emitting Diode, light-emitting diode, is a way to convert electrical energy into visible light, solid-state semiconductor devices, which can be converted directly into electricity to light.
These two English names, explanations, and can be seen: LCD, refers to the liquid crystal display; LED, refers to the selection of LED backlit LCD display. Therefore, a direct comparison between the two is not appropriate, however, Xiao Bian also wrote the title why do compare it? This was extended talk about, LCD primary divided into two categories, one category is selected traditional CCFL backlit LCD display, and the other is an optional LED-backlit LCD monitor. Shopping on the masses, many consumers directly to the first class monitors called LCD, second display called LED.
Two kinds of backlight type, CCFL and LED, are cold-cathode fluorescent tubes and light-emitting diodes, during which of course is LED (light emitting diodes) function is very good, energy saving, environmental protection, small size, high brightness, stylish. CCFL (cold cathode fluorescent tube) will not elaborate, that is to say the people called LCD, LCD TV now use the backlight are now available throughout the LED (light emitting diode).
LED TV, strict sense should be called “LED-backlit LCD TV”, the imaging principle and there is no essential difference between CCFL method, except that the backlight varieties make changes, replaced by a cold cathode fluorescent tube light-emitting diodes, and can not technical innovation is the foundation said.
Therefore, simple speaking, LED, and the difference lies only in the LCD backlight, a liquid crystal panel itself does not require any modification. That both panels are the same, the operating principle of the biggest differences is that some of the backlight.
Conventional LCD TVs (optional CCFL backlight TV) screen brightness deficiency, face painting will be dark, today’s technology, LED TV is definitely an advantage: the screen effect is very good, significantly improved brightness, the screen reflects the enhanced shading, highlighting layering, contrast, bright colors can be useful degree of advancement; addition, the screen will not dim yellow, and energy saving and environmental protection, the screen can be made even more slim.
LED life expectancy is very long, the use of the usual life expectancy is also up to 100,000 hours, if the boot 5 hours per day accounting, a selection of LED backlighting LCD TV can use for nearly 55 years.

The rapid development of LED industry in 2020 will break the 60 billion dollars

According to market research organization estimates, in 2012 the global LED lighting mall planning approximately $ 10.4 billion, compared with 2011 growth of 183%. Primary product prices due to rapid decline (2012 LED bulbs uniform price drop compared to 2011 approximately 29 per cent), femoral artery and need to grow, particularly high compatibility, low prices, more so rapid LED lighting alternative sources to carry out. Followed LED lighting prices continue lower, the number of planned rapid expansion, in 2013 the global LED lighting mall planning to maintain 30% growth can be expected to be ups and downs, in 2020 the global LED lighting production point of $ 65.8 billion.
LED lighting in the future to carry out the main points of shopping malls, still lies in mainland China, Europe, the United States, but also necessary to pay attention to related standards, standards, energy efficiency needs, local protectionism, and so non-tariff trade hampered. The Asian region is currently the world’s premier LED lighting disposal area, but also the use of LED lighting largest area mall share in 2011 reached 40%. Government assistance is being foremost, high economic growth, frequently pushing up the construction activities.

In the meantime, Youyi Shopping in Japan to promote the use of LED lighting are most active. 2011 Japanese LED lighting alternative mall planning to reach U.S. $ 952 million, is expected in 2012 to reach 1,203 stores planned millions of dollars.
Optoelectronics Technology based on 1/24 at the “2013 LED skills and future use of forward-looking trends in the use of shopping centers on the individual point of view, the current LED lighting is used in the construction of the primary lighting, outdoor lighting, industrial lighting, hospital lighting, commercial lighting, home lighting , office lighting, etc. In the meantime, the construction of lighting is the use of LED lighting pilot stores until 2010 were once the greatest use of LED lighting shopping malls, with LED lighting penetration rate is the most rapid increase in the use of the field, in 2012 LED lighting construction of shopping malls lighting penetration rate up to 56%, but also because of shopping malls tend to sophisticated, growth resistance has slowed. increase in product categories also indicates that the development of LED products, LED spotlights, LED downlights and so on.
Outdoor lighting is to benefit from the government invented shopping needs, including street lighting, public lighting, etc. femoral artery of LED outdoor lighting mall planning growth. Department of industrial lighting is needed due to industrial high lumen output, making use of LED lighting increases slowly, in 2012 the use of LED lighting in the field of industrial lighting penetration rate of only about 6%.
LED lighting in commercial lighting application, then the function of lighting system from the early and gradually turn-based lighting use, high turnover rate due to commercial lighting, prolonged use, making LED lighting penetration rate increased simultaneously with the mall planning, 2012 LED lighting commercial lighting, shopping malls to reach 15% penetration rate.
Lighting is the world’s largest home shopping application, LED lighting system to illuminate the lamp quickly cut into the shelter malls, an alternative to traditional light bulbs, but the price sensitivity of consumers about the high, so in 2012 at home lighting LED lighting penetration rate of about 13 shopping centers %, have yet to be promoted.
Office lighting to save energy and appeal, LED lighting to replace traditional fluorescent tubes are mainly aspirations cut office lighting market, but LED tube T5 fluorescent tubes is also necessary to face price competition, which in 2012 penetration rate only about 11%, the same as there is still much room for growth.

2015 years LED market in full swing in Europe

“2011-2015 European LED lighting mall statements” that the European rapid LED lighting stores carry, in addition to energy-saving concepts for the European citizens, another important factor is the European high-energy commodity price brings incentives. High electricity prices on LED lighting is an important driving force appropriate to an alternative to the traditional 40-watt incandescent bulb 7 watt LED bulb, for example, if the point of 8 hours per day accounting, month (31 days) after a month can save Beyond 8 kWh (kilowatt hours) of electricity tariff terms of EU-27 accounted for, on behalf of an LED light bulb on electricity bills per month than traditional incandescent save about $ 2.

Looking ahead, there are about LED commercial lighting appropriately high to wait. Wave of anti-nuclear countries to follow progress in the future there will be no decline in national tariff space, making energy demand will be higher. Estimated 2012 onwards LED lighting will quickly drop the price, estimated 2015 European LED commercial lighting stores will grow to $ 1.9 billion, compared with 2011 growth of space will be sevenfold.

　　Pointed out that if a higher power consumption or commercial lighting outdoor lighting, use LED light source will be able to save more costs, not Everbright wattage into a small wattage more significant economic benefits, compared to traditional light bulb to heat Low heat dissipation can be reduced breath cycle power to reach all the power-saving effect. Thus it can be said that high electricity prices in Europe to promote the development of LED lighting also accelerated after Japan is one of the important elements.
In some indoor lighting, lighting stores in Europe has always been Philips, Osram and the United States and other world manufacturers strange effects. In the meantime, Philips and Osram LED lighting trends lead Europe, they not only continue planning the traditional lighting, path lighting design roots in traditional channels, but also to promote the program to open LED product, antennae also extends to more pathways. European LED lighting companies more cautious use of LED science, the selection is from the light source, LED module color temperature, brightness should work together, luminous viewpoint to be fixed. Query, usually in some interior lighting color temperature, the European lighting match favorite warm white yellowish color temperature, lighting color temperature is normally used for home favorite between 2500 ~ 2700K; if some places in the commercial lighting color temperature of about 3000K for the bulk, but The demand for commercial lighting, high color rendering, usually demand to 80 or more.
Usually people in the European premier supermarkets and retail shops is also very simple purchased below 10W LED bulb and candle lights. But all concerned, LED home lighting throughout the mall did not, the primary is still based on the new case and other high-end luxury mall usage is higher. LED lighting Products  prices are still much higher than traditional lighting lamps, plus LED light bulb can replace traditional light sources viewpoint constraint, so that the end consumer is still on the LED light source adopted shelter looked emotions.

Recently, China-related government tenders and planning have proposed, so most LED manufacturers on the domestic market size is estimated to be more optimistic. But in fact, there are obvious gap for many construction or government tenders, size and scale project execution, coupled with local interest disputes, So whether manufacturers can obtain the expected profits in the market remains to be seen, and it should not be too optimistic.

Even if the loss, many companies will choose struggling. Based on what industry says, LED products sell $ 25 per thousand lumens last year, when it reduced to $ 2 per thousand lumens, the market will mature, and this takes about five years. In five years, how many companies can maintain? The reshuffling in last year has been brewing and restructuring, there will be very much less competitive enterprises that have been eliminated. Many companies are still selling LED lights, but with other products’ support the development of enterprises.
GLII think in the next 3-5 years, if domestic LED lights enterprise want to continued competitiveness, it must have the following characteristics:1, except LED lamp products, other applications should have good market share, and thus there will be a good LED lights funding and technical support; 2, the upstream companies have a good reserve, including chips, packaging materials and devices supply; 3, LED enterprises should have a certain stage export capacity; 4, with good local government resources. Otherwise business is difficult to stick to it as demonstration project in the current domestic tepid, “Ten thousand ten cities” plan did not steadily situation
