A lighting apparatus (110, 110a, 110b, 110c, 111) includes a base unit (20) and a light emitting unit (10E). The light emitting unit (10E) includes a substrate (10), a light emitting device (11a) and a reflective layer (12a). The substrate (10) is provided around a first axis which is along a direction from the base unit (20) toward the light emitting unit (10E). The substrate (10) includes a portion having a tubular configuration opening downward from above. The tubular portion includes a plurality of light emission side surfaces (11) disposed alternately around the first axis with a plurality of reflection side surfaces (12). The light emitting device (11a) is provided on each of the plurality of light emission side surfaces (11). The reflective layer (12a) is provided on each of the plurality of reflection side surfaces (12). The reflective layers (12a) are configured to reflect at least a portion of light emitted from the light emitting devices (11a), |
