In this embodiment, as shown in FIG. 1A, there are two pairs of sockets 10 for detachably holding two straight tube fluorescent lamps 4 and a lighting device 11 for lighting each fluorescent lamp 4. The instrument body 1 is disposed so as to face the wall surface A, the light shielding plate 2 is disposed on the opposite side of the wall surface A with the instrument body 1 sandwiched between the instrument body 1 and the wall surface A. The light shielding plate 2 and the pair of support portions 3 that support the instrument main body 1 so as to leave a predetermined space between the wall surface A and the light shielding plate 2.

  The instrument main body 1 is formed in a box whose length in the longitudinal direction substantially coincides with the length in the longitudinal direction of the fluorescent lamp 4, and 2 at each end in the longitudinal direction of the mounting surface 12 facing the wall surface A. Sockets 10 are provided one by one. The socket 10 is juxtaposed along the vertical direction at each end, and thus each fluorescent lamp 4 is attached to the mounting surface of the appliance body 1 so that the direction substantially perpendicular to the longitudinal direction coincides with the vertical direction. 12 is attached. A lighting device 11 for lighting the fluorescent lamp 4 through a socket 10 is provided inside the appliance body 1, and an external power source (not shown) is connected to a power supply terminal block 13 provided in the lighting device 11. ) Is connected, the power is supplied to the lighting device 11 and the fluorescent lamp 4 is lit.

  The light shielding plate 2 is made of a substantially rectangular long metal plate, and the length in the short direction and the length in the long direction are both longer than the length in the short direction and the length in the long direction of the instrument body 1. Is formed. Further, at both ends in the longitudinal direction of the light shielding plate 2, as shown in FIG. 1 (c), substantially rectangular parallelepiped support portions 3 that protrude toward the wall surface A are integrally formed. 3 is attached to the wall surface A by attachment means (not shown), so that the instrument body 1 and the light shielding plate 2 are supported with a predetermined distance from the wall surface A.

  Here, when the instrument body 1 is attached to the wall surface A as in the prior art, as shown in FIG. 2 (b), most of the instrument body 1 enters the field of view when viewed from the lower side, that is, the floor side. A feeling of pressure is felt and the design is impaired. On the other hand, in the present embodiment, as shown in FIG. 2A, even when looking up from the floor side, the instrument main body 1 is hidden by the light shielding plate 2, so that the feeling of pressure is reduced and the design is impaired. Absent. Further, since the two fluorescent lamps 4 are arranged on the mounting surface 12 of the instrument body 1 so that the direction substantially perpendicular to the longitudinal direction and the vertical direction coincide with each other, the upper fluorescent lamp 4 from the upper side, that is, the ceiling side. Since the irradiated light is blocked by the fluorescent lamp 4 on the floor side, it is possible to suppress dazzling by irradiating the floor side with more light than necessary. Furthermore, since the appliance main body 1 is installed away from the wall surface A, the heat dissipation of the lighting device 11 can be improved, and therefore it is not necessary to enlarge the appliance main body 1 in order to improve the heat dissipation. Further, when the appliance body 1 is attached to the wall surface A as in the prior art, the wall surface A may be discolored by the heat generated by the fluorescent lamp 4 and the lighting device 11 by being installed for a long period of time. Thus, discoloration can be prevented by installing the instrument body 1 away from the wall surface A.

  By the way, in order to turn on the fluorescent lamp 4, it is necessary to route the power line 13a from an external power source and connect it to the power terminal block 13 provided in the lighting device 11. The signal line 14 a needs to be routed from an external dimmer (not shown) and connected to the dimming terminal block 14 provided in the lighting device 11. When connecting the power supply line 13a and the signal line 14a to the terminal blocks 13 and 14, it is necessary to route the power supply line 13a and the signal line 14a so as not to be close to each other so that noise is not generated in the signal line 14a.

  Therefore, as shown in FIG. 4, an insertion hole (not shown) for inserting the power supply line 13a is provided through one support portion 3 (right side in FIG. 4), and the other (left side in FIG. 4). By inserting an insertion hole (not shown) through which the signal line 14a is inserted into the support part 3, the power supply line 13a and the signal line 14a are passed through the insertion holes of the support parts 3 different from each other. It can be connected to the bases 13 and 14. For this reason, the power supply line 13a and the signal line 14a can be routed so as not to be close to each other, and noise can be prevented from occurring in the signal line 14a.
