Taiwan: LED lighting into trillion industry needs to break through

The rise of the global trend of energy saving and environmental protection, Taiwan's "Ministry of economy" before the date of announcement will be fully out of incandescent lamps in 5 years, and in 2008 will grant 130 million yuan NT, in the "city" of 8 meters below the non Road, with more than 4 thousand and 300 LED lights. At present, governments around the world have developed a number of energy saving policies, as the protagonist of the LED lighting source, providing a specific period of development, but also depicts a bright future of green energy industry.

At present, the market is still in the general lighting incandescent lamp and halogen lamp, fluorescent lamp, the mainstream lighting has become one of the important sources of global energy consumption, and the lighting energy consumption rate of increase rate of increase is greater than the overall energy consumption, the rise of LED lighting, become the current required. The Ministry of economic estimates, after the overall elimination of incandescent lamps, it is estimated that Taiwan can save about 800 million kwh of electricity per year, reducing emissions of nearly 500 thousand tons of carbon dioxide, carbon equivalent benefits of afforestation of the 27 million 840 thousand trees.

The luminous efficiency of development speed subsequent growth

The support of strong government background, is to protect the LED all the way through the smooth stage, or in the process of generational accident come to grief, it is the key factor, the application of LED growth must enhance the speed advantages and complement each other, Nichia announced in 1993 a new milepost blue LED, 3 years after the addition of yellow phosphor excitation into white LED, white LED from opening era.

From the white LED luminous efficiency, the industry in more than 1 years ago the commercialization of production specifications can reach 50 lm/w can be considered a good result, in 2008 further increased to 70 lm/w, the level to replace traditional light bulbs or halogen lamps, and LED manufacturers to Nichia luminous efficiency of 150 lm/w in the laboratory, than in the United States Optoelectronics Industry Development Association (OIDA) set in 2012 to reach 150 lm/w, reaching about 6 years earlier.

LED lighting applications market into the ultimate dream is not accessible, but in addition to LED street in 2007 small trial and emerging commercial decorative lamps, 2008~2010 years will be an important period of growth of LED lighting. According to the Optoelectronics Industry Association (PIDA) estimates, in the absence of light, 2008 LED light source will grow 13% in 2007, reaching $98 million, in 2009 will officially exceed $100 million. IEK also believes that with the continuous improvement of LED technology and a wide range of applications, is expected in 2010 LED lighting market size will reach $771 million, 2006~2010 compound growth rate of 39%.

LED from the semiconductor process started, now enter into the lighting industry, must be integrated through various technical aspects of light, electricity, heat, etc., to enhance the technology, market maturity, whether with the Taiwan LED factory will be how to cut to create high added value, following the discussion.

The global environmental awareness incandescent lamp will go down in history

With energy saving and carbon reduction issues continue to strengthen, the development of LED lighting in North America, Europe, Japan, and other regional development the most active, including the European Union called for the elimination of the traditional incandescent lamp, the United States passed a bill to vigorously promote LED lighting, incandescent lamp, Australia that will disable the "11th Five-Year plan" will be put forward, solid state lighting declared a national focus on the development of the column in 2008, the government of Japan, is expected within 3 years will gradually stop in the domestic production and sales of incandescent lamp etc.. Before the success of the LED into the general lighting, LED street lamps become the most visible indicators of energy saving policy, the government's policy will be the first to promote LED street cut.

Comparison of energy saving policies in the world

LED has the advantages of long service life, small volume and low energy consumption advantages, is regarded as the next generation of lighting in the main, but LED is also facing high cost performance, high uncertainty and difficulty in the development bottleneck of replacement, the current global lighting opportunities up to tens of billions of dollars in LED high price limit, prompting LED will gradually penetrate from the niche market, commercial lighting and special lighting will be the first to show the effect.

Leading application of LED street lamp for outdoor lighting

The current global up to more than 100 million lights, road lighting with mercury lamp and high pressure sodium lamp as the main source, but because of the traditional street light hazardous substances containing mercury components will be gradually eliminated, LED Street buyers are mostly from the government public project, in 2005 the world's first LED street in Holland officially on 2007 lighting, countries have entered the demonstration in nature, after half a year ~1 year test period, the estimated 2008~2012 years will enter the high growth period.

LED street lamp with a height of 8 metres high pressure sodium lamp compared to LED power consumption of 60 watts, and the power consumption of 250 watts of high-pressure sodium lamp source, although the 2 are more than 3 times the price difference, but the LED lamp life up to 50 thousand hours, the use of high-pressure sodium lamp life of 4000 hours, LED lamp used in electric power consumption 2 the year is about 530 degrees, high pressure sodium lamp is required 2200 kwh of electricity consumption, after 2 years in use, if the total cost and maintenance cost, and the cost is almost the same LED high pressure sodium lamp.

LED warm white street lamp is suitable for fog Road, park landscape road can use cold white LED street lamp

Professor Huang Bingjun pointed out that, compared to the 400 Watt mercury lamp 100 watt LED lamp brightness and equal, continuous use in 12 hours a day, 1 days LED lamps can save 10 yuan electricity, calculated in accordance with the Taiwan 1 million 350 thousand street, 1 years can save 4 billion 500 million yuan in electricity.

However, the driver of the street lamp device is the government, but the plight of the LED street lamp is also a problem of different countries, coupled with LED street lighting and wind resistance design can be applied to different regions and the climate is still in doubt
