Abstract
Disclosed is a light emitting device to reduce the number of components and elements of a light emitting device and a lighting device having the light emitting device, and simplify and miniaturize the structures of these devices. With this light flux controlling member (), a total reflecting surface () functions like a reflecting member, light from a light emitting element (LED, for example) () that is incident from an input surface () and that arrives at the total reflecting surface () is total-reflected by the total reflecting surface () toward the output surface () side (including a first output surface () and second output surface ()), and the illuminating light from the second output surface () is superimposed upon the illuminating light from the first output surface (), so that the light from the light emitting element (LED, for example) () is used efficiently and illuminates the illumination target surface () over a wide range.
