under the guidance of the development of low-carbon economy has become nanchang advantage of advanced manufacturing indusy and continue to broaden the field of development, to sengthen international cooperation, organized each year by large-scale investment activities, through the provincial government support and promotion, many taiwan-funded enterprises have settled in nanchang; for the consolidation of economic development on both sides of the long-term stable and friendly cooperation, the jiangxi provincial people's government, convention approved by the office of nanchang, jiangxi science and technology department, people's government of nanchang city, jiangxi province people's government taiwan affairs office, nanchang technology bureau, the taiwan business association and the hong kong exhibition group partners joint institutions and the media indusy more than 200 co-organized in 2010 on september 26 to 28 in the fifth nanchang international .
los angeles neon signsled light intensity, light color or color temperature, to achieve illumination, the color temperature of natural light changes the simulation, in line with human circadian rhythms to light curve. sensors can also be officers, as well as with different colors of light, so lighting scenarios that match specific application needs and psychological needs of the user function, the so-called scene lighting.the fifth cenal china investment and ade expo and the 2010 cross-sait (nanchang) international led show time: 26-28 september 2010 venue: international exhibition cene, nanchang invitation organization: sponsor: nanchang, jiangxi science and technology agency people's government taiwan affairs office of jiangxi provincial people's government .
neon signs wholesalefor illusation, we assume that the led material is gaas, the material's refractive index is n1 = 3.9, the interface with the chip contacts the air, its light refractive index n0 = 1, the light from the optical communication theory to know the law of refraction, two different interface refractive index is not the same, the perpendicular to the interface of the light reflection function can be used the following equation to represent: r (l) = [(n1-n0) / (n1 + n0)] 2 & time100% for gaas and air , then there is, r (l) = [(3.9-1) / (3.9 +1)] 2 & time100% = 35.02 this means that there are 35.02% of the photons will be reflected back to the gaas material, which reflected back chip, can not escape into the air, only 64.98 percent are likely to escape into the air.
