Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lighting fixture.

[0002]

[Prior art]

 A conventional example is shown in FIGS. 5 and 6. That is, in this lighting fixture, the reflector 73 is attached to the fixture 71 on the lower surface of the fixture body 70 with the attachment screws 72, and the pair of lamp sockets 74 protruding from the reflector 73 are attached to both ends of the fixture body 70. A lead wire 76 exemplifying VVF, which is a power input line connected to the terminal block 75 of 0, is wired inside the reflection plate 73. 77 is a lamp.

[0003]

[Problems to be solved by the device]

However, in this luminaire, when the lead wire 76 hangs down as shown in FIG. 5 and the distance L ₁ to the lamp 77 becomes short, noise from the lamp 77 easily enters the lead wire 76, which may cause power terminal noise or There was a drawback that the power noise was large. Therefore, an object of the present invention is to provide a lighting device in which the distance between the lead wire and the lamp is increased.

[0004]

[Means for Solving the Problems]

 The luminaire of the present invention has a reflection plate which is substantially V-shaped and has an attachment rod installed between the inner slopes thereof, and an attachment spring for holding the intermediate portion of the attachment rod on the lower surface thereof, and the attachment spring described above. An instrument main body having a substantially U-shaped guide plate covering the width direction of the reflecting plate on the lower surface and having a slit formed in the center of the guide plate for allowing the mounting rod to enter, and an instrument main body that is wired on the lower surface of the instrument main body. It is provided with a lead wire penetrating the guide plate, and a pair of lamp sockets attached to both ends of the instrument body and projecting to the front side of the reflection plate.

[0005]

According to the structure of the present invention, when the mounting rod is inserted into the slit of the guide plate and pushed into the mounting spring so that the reflecting plate is placed on the instrument body, the mounting rod is clamped by the mounting spring. It is attached to the body of the device. In this case, since the lead wire is supported by the mounting rod that has passed through the guide plate and entered the slit, the lead wire does not hang down to the lamp side and the distance to the lamp can be increased, which results in power terminal noise and Power noise can be reduced. Further, since the mounting rod is installed inside the reflector, the width of the reflector, which tends to vary, can be stabilized and deformation of the reflector can be prevented. Further, the slits provided in the guide plate can absorb the variation in the position of the reflector in the longitudinal direction of the instrument body when the reflector is attached.

【Example】

 An embodiment of this invention will be described with reference to FIGS. That is, this illuminator includes a reflector 1, a fixture body 2, lead wires 3, and a pair of lamp sockets 4. The reflector 1 is substantially V-shaped, and a mounting rod 5 is installed between the slopes on the inside thereof. In the reflector 1 of the embodiment, both side portions 6 are bent inward, and the top portion forms a flat portion 7. The mounting rod 5 is formed by bending both sides 8 of the rectangular plate so as to incline inward, and attaching pieces 9 are extended at both ends. The attachment piece 9 is attached to the reflection plate 1 by joining means such as rivets or welding.

The instrument main body 2 has a mounting spring 10 for holding the intermediate portion of the mounting rod 5 on the lower surface, and also has a substantially U-shaped guide plate 12 for covering the mounting spring 10 in the width direction of the reflection plate 1. A slit 11 is formed in the center of the guide plate 12 which is provided on the lower surface and into which the mounting rod 5 is inserted. The instrument main body 2 of the embodiment has a rectangular plate shape and has hanging pieces 13 on both sides. The mounting spring 10 has a substantially Ω shape, and both end portions 10a are inclined outward so as to form a guide, and the central portion thereof is attached to the instrument body 2. Both end pieces 15 of the guide plate 12 extend horizontally in opposite directions and are attached to the lower surface of the instrument body 1 by known attachment means. The slit 11 has a width that is slightly larger than the width of the mounting rod 5 and serves as a guide when the mounting rod 5 enters.

The lead wire 3 is wired on the lower surface of the instrument body 2 and penetrates the guide plate 12. The lead wire 3 is an example of a VVF wire for power input connected to the lighting circuit from the terminal block 16. The pair of lamp sockets 4 are attached to both ends of the fixture body 2 and project to the front side of the reflector 1. In the embodiment, the lamp pin of the cap at one end of the lamp 14 is inserted into one of the pair of lamp sockets 4 and pushed in to connect the cap at the other end of the lamp 14 to the lamp socket 4.

Reference numeral 17 is an end plate. In the embodiment, a plurality of lighting fixtures are arranged in a row in the longitudinal direction of the fixture body 2. According to this embodiment, when the mounting rod 5 is inserted into the slit 11 of the guide plate 12 and pushed into the mounting spring 10 so that the reflecting plate 1 is covered with the fixture body 2, the mounting rod 5 is clamped by the mounting spring 10. The reflector 1 is attached to the instrument body 2. In this case, since the lead wire 3 is supported by the mounting rod 5 that has entered the slit 11 through the guide plate 12, the lead wire 3 does not hang down to the lamp 14 side and the distance L ₂ (Fig. 3) from the lamp 14 is maintained. Therefore, it is possible to reduce the power supply terminal noise and the power noise. Further, since the mounting rod 5 is installed inside the reflection plate 1, the mounting rod 5 is a press work of a small item, so that the dimensional accuracy is easy, but the bending process of the reflection plate 1 has a large variation. It is possible to stabilize the width dimension of the reflection plate 1 and prevent the reflection plate 1 from being deformed. Further, the slits 11 provided in the guide plate 12 can absorb variations in the position of the reflection plate 1 in the longitudinal direction of the instrument body 2 when the reflection plate 1 is attached.

[0010]

[Effect of device]

 According to the luminaire of the present invention, the lead wire is supported by the mounting rod that has passed through the guide plate and entered the slit, so that the lead wire does not hang down to the lamp side and the distance to the lamp can be increased. Power supply terminal noise and power noise can be reduced. Further, since the mounting rod is installed inside the reflector, the width of the reflector, which tends to vary, can be stabilized and deformation of the reflector can be prevented. Furthermore, the slits provided in the guide plate have the effect of absorbing variations in the position of the reflector in the longitudinal direction of the instrument body when the reflector is attached.
