exhibition cene expo 2010 in cenal china across the taiwan sait (nanchang) international led exhibition area of the expo is expected to more than 20,000 square meters and over 300 exhibitors to be the audience 20,000 people. 2010 cross-sait (nanchang) international led show, meticulous organization, spirit attack, the exhibition to promote cross-sait cooperation and accomplishing the realization of economic innovation and brand image event, continuing to create "cross-sait first international exhibition of led" for technology and economic innovation and development of new ideas and new impetus for the indusy to promote quality products and provide new channels for scientific and technological achievements.
los angeles neon signsanother application is based on the dali bus wider conol mode, the mode of addressing nodes within the system, data signals and address from the insuction combination, grouping of different lighting units can be flexible and achieve a variety of combinations, and set of 16 kinds of lighting scenarios, system reliability, stability, good compatibility. each dali network node, but not more than 64, does not facilitate the application of large-scale lighting situations. in addition, dali system is slow to refresh, limit the led's artistic ability.
neon signs wholesalehowever, led light-emitting if a point when the full launch of its critical half-angle boundaries and the interface of two materials θc refractive index is related by the following formula: θc = arcsin (ndn1) for gaas and air: θc = arcsin (1/3.9) = 14.90 ° boundary critical angle for the whole firing 29.8 °, above which can not be fired into the air, it is clear that in terms of a sphere, this point is only 8.27% of the area to the whole fired, apparently the internal quantum efficiency is exemely low. led chip, of course, it is a six-sided, not a point source, excluding the elecode in the light barrier, this six-sided six light-emitting surface can have a full critical angle, a total of 49.6% of the light areas.
