As shown in FIGS. 33 to 35, the connection unit 700d of the lighting device 1d has a back frame 720db, a front frame 720da, and a frame bracket portion 710d. The back frame 720db is a member to be attached to the attached portion 10, and has an L-shaped cross section. A mounting hole 720dd into which a screw or the like is inserted is formed in the back frame 720db. The back frame 720db is fixed to the mounted portion 10 by inserting a screw or the like into the mounting hole 720dd. The front frame 720da is a member attached to the back frame 720db and accommodating the lighting fixture 100 and the light source unit 200 between the front frame 720da and the back frame 720db. The front frame 720da has an L-shaped cross section, and a front opening 720dc is formed. The light emitted from the light source unit 200 travels to the irradiation target space through the front opening 720 dc. The frame bracket portion 710d is attached to the surface of the back frame 720db where the mounting hole 720dd is not formed. The lighting fixture 100 is placed on the frame bracket portion 710d. As a result, the heights of the luminaire 100 and the light source unit 200 are adjusted.

According to the fifth embodiment, even if the attached portion 10 is a wall, the lighting device 1 can be easily attached to the attached portion 10.

In the first to fifth embodiments, the case where one light source unit 200 is installed has been illustrated, but by increasing the length of the bracket main body 711 in the width direction (Y-axis direction), the light source unit 200 can be reduced to two. More than one may be installed. Further, by appropriately changing the length of the bracket main body 711, it is possible to obtain a new lighting device according to the size of the existing lighting device when the lighting device is renewed or the like.
