Demands for developing lightings and lamps which can meet eco-friendly needs for dealing with global warming problems are increasing. Consequently, R&D for so-called green lightings like OLED lamps is rapidly progressing. New devices having flat-panel-shape require different measuring method from conventional lightings such as measuring point source and line source lightings. So, four different methods are analyzed for finding appropriate method for flat lightings. The analysis will be helpful to evaluate and standardize luminous flux measuring method for flat lightings. Besides, evaluating uniformity for flat lighting is dealt with in this paper.
