Форум (онлайн-игры, travian).

last  2009 china (nanchang) international led landscape lighting and urban development in all sectors with the support of a successful conclusion. the show more than 60 exhibitors from all over the couny, but also by the philips lighting, kingsun, crystalline day lighting, shanxi guangyu technology, bronte optoeleconics, name-core technology, the source of yu, hua hin technology, maohsing technology companies such as love lide song support. most exhibitors expressed satisfaction with the effect of the show and have a song interest in participating in the next show.    main activities 1, cross-sait led and photovoltaic indusy forum 2, the cross-sait business ceo networking reception led 3, led technology across the taiwan sait forum 4, led products and promotion will highlight .   los angeles neon signs (http://www.flashingboards.com/)
the future, led lighting in the room will be widely used, its combination of technology and lighting conol can get even better results. combined with the lighting conol led lighting conol is the key to the use of computer, wireless data ansmission or power line carrier communication technology and eleconic conol technologies such as a disibuted lighting conol system, to achieve the sength of the light intensity adjustment, timing conol, to achieve lighting regionalization of the scene, personalized conol [1]. generally use the bus conol mode, requiring conolled lighting to digital dimming, and has good fast response. lighting conol is generally present form by bus, on the halogen lamp, rectifier with digital dimming digital dimming fluorescent lamps, etc., neon signs wholesale (http://www.flashingboards.com/)
in fact, led due to the exaction elecode, fixed to the upper lead frame reasons, have failed six sides out of the light, which is less than 49.6% of the entire emission region. led internal quantum efficiency is usually only about 20%, it has much room for improvement, is to sucture comprehensive led chips, packaging sucture, material refractive index and other factors to be addressed to improve the light efficiency. in recent years because of environmental protection, energy conservation, the comprehensive advantages of the semiconductor, led instead of aditional light sources for general lighting has been hard-edged, but the led luminous efficiency to a greater breakthrough can be achieved only widely used, because the luminous efficiency is applied to the data, to just like the above to improve luminous efficiency and eleco-optical efficiency of the internal quantum efficiency is closely related!business signs (http://www.flashingboards.com/)
