| Detailed Product Description: | The three main problems typical near-infrared sensing system need to be addressed are: light source and optical transmission systems, and in some places it is called a radiator or radiator, mainly based on infrared LED or laser; · target object of interest objects which are subjected to radiation source subsystem; · light detector or light sensor (mainly based on a camera or a photodiode, etc.), measuring the amount of reflected light of the target object. To be successful, such as simulation and ultimately achieve light intensity sensor, you need to understand from the light to the sensor this entire optical path on each link. Generally need to answer three key questions. For a given system, a light source, the number of optical power or luminous flux reaches the target object? How much is reflected to the sensor, or sensor captures? Is eventually captured luminance of light to meet the requirements to obtain reliable information? After years of development, China's LED industry chain has been maturing, companies throughout the LED substrate, LED epitaxy, LED chips, LED packaging and LED applications for each industry segment. Throughout the whole industry chain, because of upstream technical and financial requirements for the higher cause of domestic enterprises rarely get involved in a bar LED, so the industry exists a small number of enterprises, small-scale features. In contrast bar LED distribution, because the downstream packaging and application of the enterprise proposed financial and technical requirements are relatively low, and this is precisely the domestic enterprise funds less technology to match the characteristics of the weak, so that domestic enterprises in these two sectors a larger number. This corporate structure of the situation leads to uneven distribution of China's LED industry mostly low-end products, companies face serious long-term price pressure. With the significant decline in the last two years the cost of LED upstream epitaxial chip wholesale bar LED, epitaxial silicon upstream, midstream package, downstream applications has formed a 1: 9 ratio of market size: 4. Judging from the entire upstream investment, wafer investment growth fell from 46% in 2011 to 10 percent in 2012 Bar LED, and downstream applications investment growth in 2011 was 21%, in 2012 it rose to 53 percent, So LED industry investment focus from upstream to downstream.
