Abstract: A lighting apparatus to be installed in an area adjacent to land is provided. The lighting apparatus includes a plurality of light sources disposed on a board and further includes a light shield. The light shield blocks a portion of light emitted from the light sources. The portion of light has a predetermined wavelength. The light shield is disposed on the board closer to the land than at least a light source disposed closest to the land among the light sources. The light shield has a shape which sends, to the land, first emission light included in the light emitted from the light sources. The shape avoids sending, to the land, second emission light included in the light emitted from the light sources. The first emission light passes through the light shield. The second emission light does not pass through the light shield.
