LED integration module is used widely in lighting area, lumens depreciationwill be an important factor of effecting the life of LED and is a apparent result ofrendering the lumens depreciation, hence, the research of lumens depreciation iscrucial significantly important. In fact, for the reason that the time of lumensdepreciation is so long that the data will be complex and, if it make experiment,there will be more factor which can effect result in the process. Studying bytheory and module can make convince condition for lumens depreciation andbedding affect.Primarily, in this dissertation, it researches the theory of lighting, which isdirected at characteristic of LED integration module, lighting character and factorcan analysis and introduce so that it can study the theory of lighting. It introducesthe affect of the material such as maturing of chip, fluorescent powder,encapsulation holder, rubber powder, solid crystal glue for LED integrationmodule.Secondly, it makes acceleration experiment for LED integration module andchooses suitable module in this subject and make expand and change it based onthe foundational theory. The temperature and current regard of lumensdepreciation as double stress in this module. Building the module, it is made upof two function transformation Gv j(s)and Gv i(s), which is computed by formulaLaplace, the expression of Gv j(s)and Gv i(s)can be got. Conforming thesystems, it can receive simple systems module. Based on the original data, suchas current, temperature, using time, put all data into the expression and getcertain value. It can be proved by this way. Anglicizing the temperature transformin math and physics, it can get the affect of temperature and current for lumensdepreciation.Ultimately, it can provide several methods of lighting topology structurewhich can effect lumens depreciation and analyze different lighting devices and stimulation for large LED integration module. The affect of number of array andlumens depreciation can be got. Under the condition of the room temperature, byinfrared testing, it can observe the temperature field of different arrays and makecolumn diagram.
