Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a mounting structure for a lighting fixture in which a socket for mounting a straight tube-shaped lamp having connection portions at both ends is disposed on both sides.

[Background technology]

Figure 6 shows a conventional socket mounting structure, in which a pair of socket bases 7' and 7' are mounted on the main body case.
8' are arranged facing each other, and sockets 3 and 4 to which the connecting parts (sealing parts) 2 on both sides of the straight tube-shaped lamp 1 are connected are mounted facing each other. One socket 3 is on the fixed side, and movement in the opposite direction is regulated by a claw piece 9 bent upward from the edge of the upper piece of the socket base 7', and the screw 10 is fixed on the socket 3.
By screwing onto the socket base 7' through the long hole 12, the fixed side socket 3 is fixed onto the socket base 7'. The other socket 4 is movable,
A screw 11 is screwed into the socket base 8' through the elongated hole 13, and the sockets 3 and 4 are tightened by the length of the elongated hole 13.
It is possible to slide in the opposite direction. In other words,
In order to absorb variations in the length of the lamp 1, the sockets 3 and 4 are fixed and movable.
Therefore, as described above, the claw piece 9 is raised only on the fixed side socket 7' to regulate positioning, and the other socket 4 is left free. FIG. 7 is a diagram showing a state in which the lamp 1 is attached.

However, in such a conventional example, since the movable side socket 4 only has the screw 11 inserted through the elongated hole 13, the screw 11 is inserted through the elongated hole 13, as shown in FIG.
The clearance between the lamp 1 and the elongated hole 13 may cause looseness, which may damage the lamp 1 when severe vibration is applied to the fixture. 1 was installed, there was a risk that the lamp 1 would be damaged if the lamp 1 was forced in. There was also the problem that when the socket 4 slid, it rattled and did not move smoothly. Furthermore, socket 3,
Since the sockets 4 are simply placed on the socket bases 7' and 8', there is a problem in that the heat dissipation of the sockets 3 and 4 is not good.

[Purpose of invention]

The present invention has been proposed in view of the above-mentioned points, and provides a lighting fixture mounting structure for the purpose of smooth sliding of the movable side socket, positioning of the fixed side socket, and further heat radiation from the socket. It is.

[Disclosure of the invention] Hereinafter, embodiments of the invention will be described in detail with reference to the drawings.
In FIG. 1, sockets 3 and 4 are arranged oppositely on socket bases 7 and 8, as in the prior art, so that socket 4 can slide in opposite directions. The upper part of the socket 3 on the fixed side is rectangular.
The flat portions on both sides of the main body 14 are held between U-shaped guide fittings 5, and the center piece of the guide fittings 5 is screwed to the side wall of the main body 14. At the tips of the side pieces of the guide fitting 5, claw pieces 15, which serve as positioning means for positioning the socket 3, are formed by folding back.
The flat part of the other socket 4 is also held between the U-shaped guide fittings 6, and the center piece thereof is connected to the main body 14.
is screwed to the side wall of the The socket 4 is guided by a guide fitting 6 so that the sockets 3 and 4 can slide in opposite directions. FIG. 2 shows a state in which the lamp 1 is installed, and the socket 4 is slid along the lamp shaft by the guide fitting 6 and fixed to the socket base 8 by the screw 11. FIG. 3 shows the state of heat dissipation by the guide fittings 5 and 6. Since the guide fittings 5 and 6 are in close contact with the flat parts of the sockets 3 and 4, the connection part (sealed part) of the lamp 1 The heat from 2 is transferred to the main body 14 via the guide fittings 5 and 6, and further to the main body 14.
Heat will be radiated from 4. Note that the guide fittings 5 and 6 are made of aluminum plates.

FIG. 4 shows a fixed side guide fitting and a socket base integrally formed, and a positioning claw piece 15 is formed from the bottom plate of the guide fitting 5. In FIG. Similarly, in FIG. 5, a claw piece 15 is cut and raised from the center of the bottom plate of the guide fitting 5.

[Effects of the invention] As described above, the present invention arranges a pair of sockets, to which the connecting parts on both sides of a straight tube-shaped lamp are attached, on a socket base so as to be slidable in opposite directions. A first guide fitting is formed that guides the socket in the sliding direction by holding the flat part of one socket in a direction perpendicular to the direction of the sliding direction, and is provided with a positioning means for positioning the socket. Since the second guide fitting is formed to guide the socket in the sliding direction by sandwiching the flat part of the other socket in the direction perpendicular to the direction, the flat part of the socket can be fixed by the first and second guide fittings. By sandwiching the two parts, the heat dissipation effect of the lamp connection part is great, and the other movable socket is guided in the sliding direction by the second guide fitting, so the socket can slide smoothly. Since the lamp axis of the movable socket does not change even when the socket is slid, the lamp will not be installed out of alignment with the lamp axis, and since the socket is held between both guide fittings, Even if vibrations are applied to the fixture, the socket will not shift from the lamp axis, so the lamp has the advantage that there is no risk of damage.
