[Industrial applications]

 The present invention relates to a lighting fixture.

[0002]

[Prior art]

 A conventional example is shown in FIGS. 6 and 7. That is, this lighting fixture has a rectangular plate-shaped fixture main body 70, socket insertion portions 71 at both ends, and is attached to the fixture main body 70 by a thumbscrew 79 to cover the front side of the fixture main body 70. A reflector 72, a socket base 74 having base ends attached to both ends of the instrument main body 70, and a pair of socket engaging portions 73 facing each other at the distal end, which are notched, and the socket engaging portion 73. A lamp socket 76 having locking grooves 75 on both sides and protruding from the socket insertion portion 71, and end plates 77 provided at both ends of the reflection plate 72 are provided. The lamp socket 76 has a socket cover 78 in the lamp mounting portion, and the lamp 80 is pushed in one lamp socket 76 in the axial direction to mount the end portion of the lamp 80 in the other lamp socket (not shown).

[0003]

[Problems to be solved by the device]

 However, in this lighting fixture, due to the gap a between the locking groove 75 of the lamp socket 76 and the socket locking portion 73, the rattling of the mounting portion 81 of the socket base 74, the deformation of the lighting device main body 72 and the variation of each component, etc. However, when the lamp 80 is attached to the lamp socket 76, the lamp socket 76 has an inclination δ as shown by an imaginary line in the figure, and the rattling of the lamp 80 causes the accuracy of the socket interval to be deteriorated.

Therefore, an object of the present invention is to provide a lighting fixture capable of preventing the lamp socket from tilting.

[0005]

[Means for Solving the Problems]

 The lighting fixture of the present invention comprises a rectangular plate-shaped fixture body, a reflector having a substantially V-shaped cross section attached to the fixture body and covering the front side of the fixture body, and the reflector plates at both ends of the fixture body. A socket base having a base end attached to the outside and a pair of socket engaging portions facing each other at the tip end, and a socket base attached to both ends of the instrument body to cover the socket base. An end plate having a receiving step portion that engages with the inside of both ends of the reflecting plate at an edge portion and a socket insertion notch portion at a position of the edge portion that is aligned with the pair of socket locking portions; The end plate has locking grooves for locking the pair of socket locking parts on both sides, and abutting parts for engaging the insides of both ends of the reflection plate at positions penetrating the socket insertion notches. Lamp Soke protruding from It is obtained by a door.

[0006]

[Action]

 According to the structure of this invention, the socket base is attached to the fixture body, the end plate is attached, the lamp socket is attached to the socket base, and the reflector is attached to the fixture body. In this case, since both ends of the reflector are engaged with the abutting part of the lamp socket, the gap between the locking groove of the lamp socket and the socket locking part, the rattling of the mounting part of the socket base, and the fixture body Even if the lamp is deformed or there is variation in each component, the lamp socket can be prevented from tilting or rattling, and the accuracy of the socket interval can be improved. Moreover, the cost does not increase because only the contact portion that engages with the reflection plate is added.

【Example】

 An embodiment of this invention will be described with reference to FIGS. That is, this illuminator includes a fixture body 1, a reflector 2, a socket base 3, an end plate 4, and a lamp socket 5. The instrument body 1 has a rectangular plate shape, but in the embodiment, hanging pieces 6 are formed on both sides, and the instrument body 1 is attached to a ceiling (not shown). Further, in order to attach the reflection plate 2, as shown in FIG. 4, a substantially Ω-shaped holding spring 7 is attached to the inner surface.

The reflector 2 has a substantially V-shaped cross section that is attached to the instrument body 1 and covers the front side of the instrument body 1. In the embodiment, both sides 21 are bent inward as shown in FIG. The fixture 8 is installed between the inner slopes, and the fixture 8 is pushed into the clamping spring 7 to attach the reflection plate 2 to the instrument body 1. The base 3 of the socket base 3 is attached to the outside of the reflectors 2 at both ends of the instrument body 1 to form a pair of socket locking portions 9 facing each other at the tip. In the embodiment, a plate material is bent into a substantially U-shape, and its both ends are used as base end portions, and its mounting portions are attached to the hanging pieces 6 by the mounting tool 14, and the pair of socket locking portions 9 are formed at the edges by notches. ing.

The end plates 4 are attached to both ends of the instrument body 1 to cover the socket base 3, and have receiving step portions 10 that engage with the insides of both ends of the reflection plate 2 at the edges. At the same time, it has a socket insertion notch 11 at a position aligned with the pair of socket locking portions 9 on the edge thereof. In the embodiment, the mounting portion 18 of the end plate 4 is fixed to the cut portion 19 at the end of the instrument body 1 with the screw 17.

The lamp socket 5 has locking grooves 12 for locking the edges of the pair of socket locking portions 9 on both sides, and abutting portions 13 for engaging the insides of both ends of the reflection plate 2 with the socket. It has a position where it passes through the general notch 11 and projects from the end plate 4. The lamp socket 5 of the embodiment is provided with projecting portions 20 that engage with the inside of the end plate 4 on both sides of the base end portion, and has a locking groove 12 formed on the surface thereof, and the contact portion 13 has the projecting portion 20. It is shaped like a tongue on the upper side. Then, the lamp 15 is connected to the lamp socket 5 by pushing the cap at one end of the lamp 15 into one of the pair of lamp sockets 5 and mounting the cap at the other end in the other lamp socket (not shown). There is. Reference numeral 16 is a socket cover for covering the base.

According to this embodiment, the socket base 3 is attached to the fixture main body 1, the end plate 4 is attached, the lamp socket 5 is attached to the socket base 3, and the reflector 2 is attached to the fixture main body 1. In this case, since both ends of the reflection plate 2 are engaged with the contact portions 13 of the lamp socket 5, the gap between the locking groove 12 of the lamp socket 5 and the socket locking portion 9 and the mounting of the socket base 3 Even if there is rattling of the parts, deformation of the main body 1 of the fixture, variation of each component, etc., the inclination and rattling of the lamp socket 5 can be prevented, and the accuracy of the socket spacing improves. Moreover, the cost is not increased because only the contact portion 13 that engages with the reflection plate 2 is added.

Although the above-described embodiment uses one lamp, it may be a two-lamp type in which each lamp 15 faces each inclined surface of the substantially V-shaped reflector 2. Alternatively, the fixture body 1 may be provided with a fixture, and the reflector 2 may be attached to the fixture with a mounting screw.

[0013]

[Effect of device]

 According to the luminaire of the present invention, since both ends of the reflector are engaged with the abutting portions of the lamp socket, the gap between the locking groove of the lamp socket and the socket locking portion and the mounting portion of the socket base are Even if there is rattling, deformation of the main body of the fixture, or variations in each component, it is possible to prevent the lamp socket from tilting or rattling, thus improving the accuracy of the socket interval. Moreover, the cost is not increased because only the contact portion that engages with the reflection plate is added.
