| description | An illumination device of the present invention includes: a light source (12); and an optical member (14) for controlling a light distribution property for light emitted from the light source (12). The optical member (14) has an entrance surface (16) and an emission surface (18) for the light emitted from the light source (12). The optical member (14) includes, on at least one of the entrance surface (16) and the emission surface (18), first lenses each producing a power which varies between an X axis and a Y axis. 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. |
