1. A lighting apparatus, comprising:
an optical unit comprising a light emitting module that includes a light emitting element mounted on a substrate, and a lens configured to control distribution of light from the light emitting module; a unit mounting plate, formed in a flat plate shape, comprising a front surface on which the optical unit is disposed; a power supply apparatus comprising a lighting circuit configured to cause the light emitting element to light; and a body configured to comprise a case main body and a top cover being openably and closably provided with the case main body, the case main body having a coupling portion for connecting a support column to the case main body, a non-translucent portion having an irradiating opening provided at a bottom surface of the case main body through which the optical unit irradiates light, and a translucent plate formed in a flat plate shape, the flat plate-shaped translucent plate being arranged in parallel with the flat plate-shaped unit mounting plate and arranged so as to fit the irradiating opening such that the non-translucent portion surrounds an entire outer periphery of the translucent plate and such that the non-translucent portion and the translucent plate are substantially arranged in the same plane, wherein the optical units and the unit mounting plate are housed in the body such that the optical unit faces the irradiating opening.
