An illumination apparatus (12) of the present invention is an illumination apparatus for irradiating a plant with light. The illumination apparatus (12) includes a light-emitting diodes (23) serving as light sources; an LED substrate (22) on which the light-emitting diodes (23) are provided; a lens (25) (an optical member) provided between the LED substrate (22) and the plant to be irradiated, the lens (25) changing the paths of light emitted from the light-emitting diodes (23); and a lens holding plate (24) (an optical member) to hold the lens (25). The lens (25) is removably attached to the apparatus. With this configuration, it is possible to provide an illumination apparatus for cultivating plants, which illumination apparatus has been improved from the viewpoint of control of heat generated by an LED and control of light distribution of the LED. |
