In other words, the load can be distributed without being concentrated on one end of the light source unit 30.

In addition, since the auxiliary function unit 31 and the auxiliary function power source 49 are disposed closer to the outer end than between the two attachment mechanisms 26, the auxiliary function unit 31 and the auxiliary function power source 49 are located at the center of the instrument body 11 in the longitudinal direction between the two attachment mechanisms 26. It can be arranged without interfering with the terminal block 22, light source power supply 24, etc. arranged in the area.

In addition, in the lighting device 10, when the auxiliary function unit 31 is a camera unit, for example, the auxiliary function power supply 49 that supplies predetermined operating power to the camera unit performs power conversion, thereby reducing noise such as switching noise. If this noise occurs, there is a concern that the images captured by the camera unit will be affected. However, in this embodiment, the auxiliary function unit 31 and the auxiliary function power source 49 are separated, and one longitudinal end of the light source unit 30 is The auxiliary function unit 31 is disposed at the auxiliary function unit 31, and the auxiliary function power supply 49 is disposed at the other longitudinal end of the instrument body 11, and the auxiliary function unit 31 and the auxiliary function power supply 49 are separated.

Connected.

In the lighting device 10, the auxiliary function unit 31 and the auxiliary function power source 49 are arranged at both ends of the light source unit 30 in the longitudinal direction, so that when the light source unit 30 is supported by the two mounting mechanisms 26, In some cases, both ends of the light source unit 30 are lowered and the central region is raised, causing the light source unit 30 to bend like a mountain. Accordingly, such deflection of the light source unit 30 can be reduced.

Moreover, since both longitudinal ends of the light source power supply 24 arranged along the longitudinal direction of the light source unit 30 are fixed to the light source unit 30 with screws, the light source unit 30 does not bend in a mountain shape. can be further reduced.

Furthermore, since the light source power source 24, the auxiliary function unit 31, and the auxiliary function power source 49 are integrally provided in the light source unit 30, the lighting device 10 can be replaced by replacing the light source unit 30 with respect to the fixture body 11.
