Green LED lighting brings the output value of 2010 billion

March 27 20:30 ~ 21:30 the night, "Earth Hour", the global number of landmark buildings outside landscape lighting will be extinguished. From the Sydney Opera House to the Palace Museum in Beijing from Hong Kong's Victoria Harbour to Dubai's seven star Burj Al Arab Hotel, from Westminster Abbey in London to New York the Empire State Building, world's 24 time zones of people passing by darkness, so that ordinary people stopped in the dark, spend 60 minutes to pay attention to and understanding of environmental protection, environmental protection into every ordinary way of thinking, way of life.
"Earth Hour" is just a fashion show and relaxing environment. We can not always turn off the lights, we can not do without lighting, we need to find more green light, LED (Lighting Emitting Diode), can make our lighting more green.
More environmentally friendly: 90% energy saving, long life times
LED is a solid state semiconductor light emitting devices. It uses solid-state semiconductor chip as the light-emitting materials in the semiconductor by carrier compound, releasing excess energy, sparking photon emission, the light of various colors directly issued. The chip color of light depends on the semiconductor material used. And computer chips, LED can be very small, even as small as a fingernail.
In 1955, the first U.S. wireless company Rubin found the gallium arsenide (GaAs) and other semiconductor alloys in the infrared radiation effect. In 1962, Nick General Electric Company developed the first practical application of visible light-emitting diodes. LED has been used only for radio or stereo power light in recent years, expanding its scope.
Now known as the fourth generation of LED light source, or green light, with energy saving, environmental protection, small size, long life and other characteristics, can be widely applied in various directions, display, decoration, backlight, general lighting and night lighting, and other areas of the city .
Philips CEO Gerard Kleisterlee said: "In technology, driven by solid-state conduction, the transistor radio, vacuum tubes were replaced by liquid crystal display TV picture tube replaced, eventually, such a change into the lighting field."
LED drivers are current, with ultra-low power consumption, single tubes can reach 0.03 to 0.06 watts, electro-optical energy conversion efficiency of close to 100%, the same lighting effects, energy-saving than traditional light sources over 90% energy saving than normal energy saving lights 50 %, and life expectancy 10 times longer than traditional light sources.
LED light source more environmentally friendly. LED lighting is not ultraviolet and infrared, there is no heat, no radiation, no glare effect. LED light source in the manufacturing process, does not involve mercury and other heavy metals, the process used on the sound, after which waste can be recycled. LED is a solid-state cold light source, no heat generation, safe touch, typical of the green light.
Wide application: the output value of tens of billions of 2010
Multi-color changes. LED light source using red, green, blue trichromatic theory, under the control of the computer technology, three colors with 256 levels of gray, and can be mixed, that can produce more than 1600 million colors.
LED combined with a variety of new technologies to achieve a more rich feature set. Traditional light sources emitting only a single effect, but LED lighting is low voltage microelectronic products, with the computer, network communications, image processing, embedded information technology, a digital and multimedia products.
Manufacturers in the progress of material and workmanship, make light-emitting chips continue to lower the cost, performance improved. U.S. LED industry market research firm Strategies Unlimited analyst Robert Steele, said: LED will be turned on and innovative new ideas for our lighting.
Currently, LED area is the most widely used for the LCD display and phone keypad backlighting, followed by building lighting, new traffic lights, car dashboard, in 2010, LED lighting products, global sales will reach 100 billion U.S. dollars.
June 2007, Apple introduced the use of mercury-free LED backlit screen Macbook Pro laptops, LED technology not only cut off by heavy metals in the manufacture and use of potential harm people, but the backlight makes the screen more uniform, reducing display power consumption.
Ford Mustang car used LED instrument panel, a total of 100 different colors for customers to choose from. Boeing's new 787 Dreamliner passenger aircraft interior also used LED, LED for lighting to create a favorable atmosphere for cross-border long-haul flight to help passengers who better to adjust the time difference.
China: LED is within reach
Beijing Olympic Games opening ceremony is not only a sports event, but also the largest ever in a LED light show. In Beijing, many traffic lights, no longer follow the traditional order of red, green and blue bulbs flashing pattern, but rather by an LED device in different colors depending on the circumstances change. In Shanghai, the lanterns, the Huangpu River are many great LED advertising screen scrolling the theme "Better City Better Life" slogan.
LED has been embedded in our lives. March 28, 2010, the reporter learned Ikea in Beijing, where have you can buy LED chandeliers and lamps. Reporter to a price of 199 yuan, and sales staff consulted LED lamp, the staff member said: This is a solar lamp work lights, do not connect the power. Of solar panels in direct sunlight sunny day 4 to 5 hours, to be 3 to 4 hours at night to ensure that the lighting needs, if cloudy, you need 8 to 9 hours.
March 29, 2010, the first solar wall in Hubei Province LED lighting system in Wuhan Building, the torch run. This is a high-tech, low energy consumption of office space, the use of transparent solar glass curtain wall, the solar energy into electrical energy, both play a common wall decoration, lighting, sound and heat insulation effect, but also for the building of the public corridors, underground parking field, outdoor road, landscape lighting to provide power. LED lighting is the incandescent light bulb power consumption is 1 / 8, the average life expectancy of 10 million hours. This system can reduce annual carbon dioxide, sulfur dioxide emissions of 9936 kg of hazardous substances.
In China, electricity for lighting the entire society is about 12% of total electricity consumption, and if all the existing incandescent lamps replaced with energy-saving, saving more than 600 billion kilowatt-hours a year, equivalent to annual power generation of Three Gorges power station . "Eleventh Five-Year" period, China will promote the 150 million energy-saving lamps, saving 29 billion kwh, reduce carbon dioxide emissions 29 million tons.
Now the worries of a global energy shortage in the context of ever-increasing, we need energy-saving environmental protection has become the most important issue face to face, LED lighting application products to attract people's attention. As a new green LED light source, will lead the future development trend of the lighting industry. LED lighting revolution in the lead, but also for environmental protection, energy conservation has made a great contribution.
