From the infrared remote control to the phone display, from traffic lights to household appliances monitor, LED (light emitting diode) is "silent" changing our city and life. Semiconductor technology, following the lead to a revolution in microelectronics industry, began to brew a new bright green "revolution" over the global. Shanghai Oriental Pearl Tower, wujiaochang "egg", Donghai Bridge ... These famous buildings have a common new light source - LED. They lit up the multicolored Shanghai, exudes a charming light at night, bright but not luxury. On August 22 -24, 2011 at the Fourth China International Semiconductor Lighting Exhibition, these new LED light source was shining. LED, light-emitting diodes, use solid semiconductor chip to release energy,it can emit red, yellow, blue, green, blue, orange, purple, and white colorful light. Small, luminous body, has been used only for electronic devices embedded on-chip power indicator. With the increasing requirements of energy saving and environmental protection, LED has been expanding the scope of application of the new light source in addition to the field of special lighting, large-size LCD TV backlighting, automotive, commercial and industrial lighting has gradually become the main application areas of LED. In 2006, the global turnover of the LED trade market is more than 7 billion U.S. dollars, with an average annual growth rate of more than 20%. LED is changing the pattern of the global lighting industry cents and brought a revolutionary impact which exert a profounder influence than the Second World War neon and other inflatable bulb invention. Power consumption is 1/10 of the ordinary light bulbs If "1/4 of our lighting lights replaced with LED, year savings equivalent to a generating capacity of the Three Gorges Power Station, from Shanghai Semiconductor Lighting Engineering Research Center Li Shu-chi said. Undoubtedly, energy saving and environmental protection is the biggest breakthrough of the light source. Relevant experts describe the LED light-emitting principle "like thunder and lightning, the traditional lamp is put a power-filament in a vacuum, and the LED is a semiconductor chip, it is illuminated by electronic mobile light,its conversion efficiency is up to 68%. In contrast, ordinary of electric light bulbs convert electrical energy to light energy,but most is converted into heat, the conversion efficiency is only 12%. Because of this, LED has energy saving and environmental protection advantages unmatched by other light sources. Under the same lighting effects, LED's power consumption is only equivalent to 1/10 of the ordinary light bulbs. In the field of special lighting, landscape lighting (neon replacement) has 70% energy saving, traffic lights (to replace incandescent)have 80% energy saving. In addition, the service life of the LED especially LED flood light used in decorative lighting in outdoor is 100 times longer than ordinary light bulbs, light has high quality and stability feature. Because LED use cold light source so that its light has less glare, no radiation, the use of it does not produce harmful substances, and recyclable waste, no pollution. Landscape Lighting "building integrated" Seen Shanghai wujiaochang the eggs will be impressed by its gorgeous bright lights at night. It is a clear picture, colorful, lifelike, computer-controlled image is constantly changing. This is the LED credit. 1,420,000 LED spot, the Wujiaochang "egg" lighting source, the light connect the dots can be connected into 14 km. The LED strip is set in the seam of the steel frame of the "egg", which does not destroy its original appearance and daytime landscape, it becomes a colorful stage lighting in the evening. It is reported that the "egg" lighting power consumption is only 80.3 kW / h, the maximum peak power consumption is 7.8 watts per square meter, if the same area is lighted by ??the other lamps display, the power consumption is more than 10 times. LED light source has advantage of structure lightweight, compact, and can adapt to a variety of geometric dimensions and space. Therefore, lighting can be designed to be made very compact appearance, suitable for installation in any building structure without affecting its overall appearance beauty. According to the the Yangpu District cityscape Authority deputy director Wang Weiping, LED display technology is applied to the urban landscape so that it can be done "building integrated", that is, the LED light source can perfectly joint the city building, so we can see the light but not light, at which time not only the big screen emits flashing lights, and more building exudes the charm of light. LED is not only colorful and rich, but the response time is short, extremely easy to be controlled. The use of the timing control circuit can achieve a variety of dynamic color change, the instantaneous change of color. In addition, it has a strong directional and hasn’t visual pollution, it can adopt cells, solar, wind, or many other energy for its power, so favored in the landscape lighting engineering. Being developed lighting display lights in the Bohai Bay Cross-sea Bridge, power supply, cables and poles and other facilities will no longer be needed, leaving the "wind, solar LED street lighting, LED landscape as one. LED industry development prospects "If we replace traditional lighting with semiconductor lighting in Shanghai landmarks, landscape lighting and public lighting, electricity for lighting of the city will be able to save 10 billion kilowatt-hours." We can predict that LED in Shanghai will be the potential. Shanghai has a unique development of LED industry market research strengths, industrialization has begun to take shape, and searching for a new round of breakthrough is to seize the commanding heights of this innovative of LED industry development. Up to 2006, Shanghai has 105 LED-related patents, and access to a number of scientific and technological achievements Award; also developed 100 national standards, industry standards and internal standard of optical industry. Shanghai 2010 World Expo bid is successful, which has promoted the construction of a new round of large-scale development of Shanghai City, Shanghai semiconductor lighting industry will also provide a vast market space for development. I believe that in the near over the city, the LED light will make the world more beautiful. With the popularity of the LED market, more and more companies are engaged in the LED lighting industry , especially the Pearl River Delta, China, our company www.lead-lighting.com with more professional LED technology and excellent quality, is unanimously committed to creating the perfect LED floodlights, LED tunnel lights and other LED lighting, relative to other industries we have more affordable price, timely delivery and perfect after-sales service is our protection, our wish is to let low-carbon green LED into the general public warm and cozy home! Together with us create a more comfortable Earth.
