Abstract: The present disclosure discloses a lighting apparatus and relates to a lighting field. The lighting apparatus includes an outer housing, an inner housing, a face ring, a functional module and a first conductive wire. A portion of the inner housing is arranged inside an accommodating cavity and separates the accommodating cavity of the housing into a light source cavity and a via cavity; the face ring is located outside the accommodating cavity and connected with the inner housing, and encloses to form an installation cavity; the installation cavity is sequentially in communication with the via cavity and the first via hole, so that the functional module mounted in the installation cavity may be electrically connected with the first conductive wire; and the first conductive wire sequentially passes through the via cavity and the first via hole to extend out of the housing.
