Abstract (en)

[origin: EP2400206A1] An illumination device of the present invention includes: a light source (12); and an optical member (14) having an entrance surface (16) and an emission surface (18) both for controlling a light distribution property for light emitted from the light source (12). At least one of the entrance surface and the emission surface has an entrance side lens surface (16) or an emission side lens surface (18). The light source (12) has an optical axis shifted away from a geometric central axis of at least one of the entrance side lens surface (16) and the emission side lens surface (18) on the entrance surface or the emission surface. This arrangement makes it possible to control a light distribution property in two directions, and consequently produce an illumination apparatus which is superior in design and which is high in horizontal illuminance and vertical illuminance.
