Description

[Detailed explanation of the idea] This invention relates to the main body of a lighting fixture.

As shown in FIGS. 1 and 2, in a conventional fluorescent lamp device, a discharge lamp ballast 2 is attached to the inner surface of one horizontal side of a groove-shaped device body 1, and a socket pedestal 3 is attached, and the lamp is attached to the socket pedestal 3. By fixing the socket 4, attaching the appliance body 1 to the ceiling 5 in this state, covering the appliance body 1 with a reflector plate 6 having a socket insertion hole, and screwing the thumbscrew 7 into the socket base 3 through the reflector plate 6. The reflector plate 6 is fixed, and then a fluorescent lamp 8 is mounted between the lamp sockets 4, 4.

In this case, the fixture body 1 can be attached to the discharge lamp ballast 2 by screwing the mounting screw 9 into the discharge lamp ballast 2 from the outside of the horizontal piece.
In order to prevent the ceiling 5 from being damaged by the heads of the mounting screws 9 when the horizontal piece is mounted on the ceiling 5, outward protrusions 1a are formed on both ends of the horizontal piece. A gap is provided between the two.

However, in such a conventional fluorescent lamp device, the end faces of both vertical pieces of the main body 1 of the device are exposed, so there is a risk that a worker may be injured by the end faces when assembling the device.

In addition, when storing the instrument body 1 after manufacturing it by press molding or transporting it to the next process, it is possible to stack a large number of them by alternating the orientation and holding two pieces together, as shown in Fig. 3. If this were done, the orientation would have to be returned to the original direction when parts were attached in the next process, making it difficult to automate the assembly work.

On the other hand, if a large number of instrument bodies 1 are to be stacked in the same direction to facilitate automation, pads 10 must be placed between each of the many instrument bodies 1, as shown in FIG. When the apparatus bodies 1 of 1 are stacked, the height becomes twice that of the case shown in FIG. 3, making transportation work difficult.

Furthermore, since the protrusions 1a are formed at only a few places on the horizontal piece of the appliance body 1, if the ceiling 5 is made of a soft material, the protrusions 1a will sink into the ceiling 5 and the ceiling 5 and the appliance body will be damaged. There were problems in that the head of the mounting screw 9 would damage the ceiling 5, and the knob 7 would not be able to reach the socket base 3, making it impossible to fix the reflector 6.

Therefore, the purpose of this invention is to provide a lighting equipment main body that can easily automate safe equipment assembly work, facilitate transportation and storage work, and securely fix the reflector without damaging the ceiling. be.

An embodiment of this invention is shown in FIGS. 5 and 6.

That is, this fluorescent light fixture uses a fixture body 11 and a socket base 3' in place of the fixture body 1 and socket base 3 shown in FIG. 2, respectively.

This instrument body 11 has a recess 12 formed in the center of the horizontal piece of the substantially groove-shaped cross-section member to an extent that the head of the component mounting screw 9 does not protrude, and the ends of both vertical pieces of the member with a substantially reverse groove-shaped cross-section. forming inward folded portions 13 and 14 on the (opening edge),
Recessed step portions 15 and 16 are formed at both corners of the member having a substantially reverse groove-shaped cross section.

In this case, the inner distance C between the two inward folded portions 13.14 is made slightly wider than the outer distance B between the vertical pieces of the double recessed step portion 15.16, and the two vertical pieces of the substantially reverse groove-shaped cross section are The height D from the lower end to the horizontal piece of the double concave stepped portion 15.16 is slightly larger than the height H from the horizontal piece of the double concave stepped portion 15.16 to the horizontal piece of the member with a generally reverse groove shape in cross section. There is.

Further, the socket stand 3' has outwardly facing both ends 3a', 3
b' is fixed to the instrument main body 11 by being held between the ends of the inward folds 13.14 of both vertical pieces and the inner surface of the recessed step 15.16.

In this way, the fluorescent lamp apparatus of this embodiment has a main body 11.
Since it has an inward folded portion 13.14 at the opening edge of the
The end faces of both vertical pieces of the instrument body 11 are not exposed, and the operator is safe without being injured.

In addition, since the inner distance C between the two inward folds 13.14 of the instrument body 11 is made wider than the outer distance B between the vertical pieces of the double concave stepped portions 15.16, one of the instrument bodies 1
The top of the other device main body 11 can be fitted into the opening edge of the other device main body 11, and therefore, a large number of device main bodies 11 can be stacked without the need for pads or the like, and the stacking height can also be reduced to that shown in FIG. This makes it possible to easily automate the instrument assembly work, and to transport the instrument body 11,
Storage work becomes easier.

Furthermore, since both sides 17 and 18 of the recess 12 in the horizontal piece of the appliance body 11 contact the ceiling 5 over the entire longitudinal direction of the appliance body 11, the appliance body 11 does not sink into the ceiling 5, and the reflector 6 is securely attached. can be fixed to,
Moreover, the head of the mounting screw 9 will not damage the ceiling 5.

In addition, if the lead wire of the instrument is passed through the cavity 19.20 formed by both vertical pieces of the instrument body 11, the horizontal pieces of the recessed step 15.16, and the inwardly turned part 13.14, the lead wire can be released. Lead wires can be protected without touching high temperature parts such as the light ballast 2.

In addition, as shown in FIG.
．． By sandwiching the lead wire 22 between the lead wire 14 and the lower surface of the horizontal piece of the recessed stepped portion 15, 16, the lead wire 22 can be prevented from sagging.

Note that the inwardly folded portions 13 of both vertical pieces of the instrument body 11.
14 and an incandescent lamp socket 23 attached to the socket stand 2
4, respectively, and the inward folded portions 13.14 are aligned with the arrows F1. The instrument body 11 is pressed in the direction of F2 and tightened.
In the case where the socket base 24 is fixed, the socket base 24 is movable in the longitudinal direction with respect to the instrument body 11, and the degree of freedom in attaching the socket base 24 is high.

Note that 25 is an incandescent lamp. Further, as shown in FIGS. 10 and 11, a tongue piece 11a is formed by partially cutting away opposing portions of both vertical pieces of the instrument body 11, and at this position, the recessed step part 15.16 is opened. On the inner surface, there is a bent piece 24a at both ends of a socket base 24' having substantially the same shape with both ends bent inward.
The socket base 24' can be fixed to the instrument main body 11 by bringing the tongues 11a into contact with each other and bending the tongue piece 11a into the hole 24b' of the socket base 24'.

As described above, the main body of the lighting device of this invention has inwardly folded portions formed at the ends of both vertical pieces of the substantially inverted groove-shaped cross-sectional member, and at both corners of the substantially inverted-grooved cross-sectional member. A main body of a lighting fixture having four stepped portions, wherein the inner distance between the two inward folded portions is wider than the outer distance between the vertical pieces of the double concave step portions, and the member has a generally reverse groove-shaped cross section. Since the height from the lower end of both vertical pieces to the horizontal piece of the double concave stepped portion is greater than the height from the horizontal piece of the double concave stepped portion to the horizontal piece of the substantially reverse groove-shaped cross-section member, the end of the vertical piece It is safe because the parts are not exposed, and when stacked, the upper part of the member with a generally reverse groove cross section gets into the lower part of the adjacent one, and the horizontal piece of the double concave stepped part becomes a contact when stacking, so it is safe to use pads etc. They can be arranged in the same direction and stacked low and stably without needing to be stacked, and when stacking, the items below will not be deformed due to weight or stick together due to friction, making it easy to automate equipment assembly work, transport and storage. It is also easy to work with.

Furthermore, since the recessed step portion is provided, parts such as a socket stand can be easily attached.
