Automatic measuring system for the parameters of LED light

Liu Jinqing Huang Yusheng(School of Physics and Optoelectronics Technology,Fujian Normal University,Fuzhou 350007 )  
LED light is a kind of new light now.Measurement of the parameters of LED light is very important.The application of personal computer control technique for automatic measurement of LED light was introduced.By using the interfacing technique of personal computer and optical-electric conversion technology,controlling step motor,which is used to drive monochromator,to scan light in the scope of visible light (380~780 nm)point to point,the distribution value of luminous intensity in correspondence with each wavelength location can be obtained.Then the color temperature and color rendering index of LED light are measured automatically by computer.
