Abstract:
PROBLEM TO BE SOLVED: To provide built-in lighting equipment which is reduced in size.SOLUTION: Lighting equipment 1 which is built in an attachment face comprises a lighting appliance main body 10 having a light source 11, and a power supply unit 20 which supplies power to the light source. The lighting appliance main body and the power supply unit are arranged so as to be overlapped on each other in a direction orthogonal to the attachment face. The lighting appliance main body has a plate-shaped heat radiation member 12 which radiates heat emitted from the light source and/or the power supply unit. The power supply unit and the lighting appliance main body are arranged so as to be overlapped on each other in a thickness direction of the heat radiation member via the heat radiation member. The power supply unit has a box-shaped box body 21, and is arranged so as to be positioned on the lighting appliance main body at one end side of the box body. An end face 272 at one end side of the box body is inclined to a direction orthogonal to the attachment face, and forms an acute angle with respect to a face 261a which opposes the lighting appliance main body out of the box body.
