Abstract:
1. A lighting apparatus comprising: a main body which includes a flat thermal conduction surface; a board which includes a front surface on which a light-emitting device is mounted, and a back surface that contacts the thermal conduction surface; an optical member which includes an annular inner edge part, a peripheral part of the board being interposed between the thermal conduction surface and the inner edge part, the optical member also including an annular inclined surface expanding outward from the inner edge part, and reflects, on the inclined surface, light emitted from the light-emitting device; and a fastening member which fastens the inner edge part of the optical member to the main body, such that the back surface of the board is pushed, in the peripheral part of the board, against the thermal conduction surface.
