【Example】

 An illuminator according to an embodiment of the present invention will be described with reference to FIG. The lighting fixture 10 is a mounting device 4 having a power wire through hole 1 for inserting a power wire, a fixture body mounting portion 2 and a fixture insertion hole 3, and a lighting component detachably mounted on the fixture body mounting portion 2. 5 and an instrument body 7 having a fluorescent lamp 6.

The attachment device 4 is formed by bending a steel plate and has an overall length L set to 500 mm. The instrument main body mounting portion 2 has a substantially L-shape protruding on both sides. The fixture body 7 comprises a substantially V-shaped reflector plate 8, a metal fitting 9, and a lighting component 5. The lighting component 5 includes two sets of lamp sockets 12 provided on the reflection surface of the reflection plate 8 and a ballast 13 fixed to the metal fitting 9. The metal fitting 9 forms an engaging portion 11 capable of elastically engaging the instrument body mounting portion 2. The fluorescent lamp 6 has a rated power of 20W.

To mount the lighting fixture 10 on the ceiling portion 14, first, the mounting screw 15 is inserted into the mounting tool insertion hole 3 and screwed into the ceiling plate 14, and the mounting device 4 is fixed to the ceiling plate 14. A power supply line 16 for supplying electric power to the equipment main body 7 is inserted from the attic into the power supply line through hole 1 and drawn into the room to be connected to the equipment main body 7. Next, the tool body 7 is pressed against the mounting device 4 from below, and the tool body mounting portion 2 and the engaging portion 11 are elastically deformed in the directions of arrows A and B, respectively, so that the tool body mounting portion 2 and the engaging portion 11 are separated from each other. Engage each other. When removing the instrument body 7 from the attachment device 4, the instrument body 7 is pulled downward to separate the instrument body attachment part 2 and the engagement part 11 and disconnect the power supply line 16.

As described above, since the fixture body 7 can be easily attached to and detached from the attachment device 4 attached to the ceiling plate 14, it is necessary to replace the fluorescent lamp 6 with a fluorescent lamp (not shown) having a rated power of 40 W. However, it suffices to replace only the main body 7 of the fixture with a fluorescent lamp having a rated power of 40 W, without removing the attachment device 4 once attached to the ceiling plate 14. Therefore, there is little effort when replacing the fluorescent lamp with one having a different rated power, and the construction is easy. Moreover, the rated power of the fluorescent lamp can be determined after the mounting device 4 is installed in advance. In addition, regardless of whether the fluorescent lamp 6 having a rated power of 20 W or the fluorescent lamp having a rated power of 40 W is mounted on the ceiling plate 14, the mounting device 4 can be used in common, so that the variety of products can be reduced and produced. It is possible to improve the property.
