Abstract
Provided is a light emitting device which can uniformly diffuse and radiate light from all the regions of the globe of an LED bulb without deteriorating light transmission efficiency. A light emitting device is provided with a light scattering/guiding globe and an LED which is disposed on one end of the light scattering/guiding globe. The light scattering/guiding globe is a body with no air released from the inside and is composed of a light scattering/guiding material having light scattering particles contained therein. The globe has the bottom surface on the side of the LED, and is provided with a first light incoming surface as a first hollow section, which is formed in a circular cone shape in the light outputting direction from the bottom surface.
