Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminaire having a socket cover for covering an end of a straight tube fluorescent lamp and a lamp socket supporting the lamp.

[0002]

2. Description of the Related Art It is known that a lighting device provided with an exposed straight tube fluorescent lamp is provided with a socket cover to improve its appearance. One example is shown in FIGS. Has been done.

FIGS. 6 and 7 show a two-lamp type lighting fixture. In FIG. 1, reference numeral 1 denotes a fixture main body directly attached to the ceiling and to which electric parts such as a discharge lamp ballast (not shown) are attached. A reflecting plate 2 is fixed to the instrument body 1 via a decorative screw 3 so as to cover the device 1. In addition, reference numeral 4 in FIG. 7 denotes a reflection plate mounting member to which the decorative screw 3 is screwed. The reflection plate 2 has a pair of oblique reflection walls 2a.
Socket fittings 5 (see FIGS. 7 and 8) are attached to both ends of the instrument body 1 in the longitudinal direction.
The lamp sockets 6 penetrating the ends of the reflection walls 2a are attached to the respective lamps. The straight tube fluorescent lamp 7 provided so as to face the reflection wall 2a is mounted on a pair of lamp sockets 6 and supported at both ends.

This luminaire has a socket cover 8 for covering the end of the fluorescent lamp 7 and the lamp socket 6, and the cover 8 is made of a synthetic resin body 9 as shown in FIGS. Inside, a metal holding spring 10 is arranged and fixed by a screw 11.

Specifically, the surface of the body 9 on the instrument body 1 side and one end surface are open. Ribs 12 extending in the height direction of the body 9 are respectively provided on the inner surfaces of the side walls 9a facing each other of the body 9, and the lamp socket 6 is provided in the space between the ribs 12 and the end wall 9b of the body 9. It is supposed to be housed. A screw receiving boss 13 is integrally projectingly provided on the inner surface of the bottom wall of the body 9 at the opening surface side at one end.

The holding spring 10 has an inclined portion 10a formed by bending a strip-shaped spring plate into a substantially U shape and bending both ends thereof away from each other. By providing the inclined portions 10a arranged in the inverted C shape, the holding spring 10 is formed with a pair of opposed end bent portions 10b. In the free state of the holding spring 10, the end bent portions 10b face each other with a separation distance B narrower than the lamp diameter A (see FIG. 8) of the fluorescent lamp 7. The holding spring 10 has a central portion placed on the screw receiving boss 13 and is housed in the body 9, and is screwed into the screw receiving boss 13 through the central portion.
It is fixed to the body 9 by 1.

The socket cover 8 having such a structure is attached by making the open surface of the instrument body 1 side face the end of the fluorescent lamp 7 and the lamp socket 6 and covering them. The arrow in FIG. 7 indicates the mounting direction of the socket cover 8.

In this attachment, first the holding spring 1
Since the slanted portion 10a of 0 corresponds to the end of the fluorescent lamp 7, the holding spring 10 is pushed open with elastic deformation. And, the lower half of the end of the fluorescent lamp 7 is the end bent portion 1
Since the holding spring 10 tries to quickly return to the original free state at the same time when it crosses over 0b, the holding spring 10 causes the end portion of the fluorescent lamp 7 from both sides in the radial direction as shown in FIG. Holds elastically. As a result, the socket cover 8 accommodates the end portion of the fluorescent lamp 7 and the lamp socket 6 therein, and is attached and held to the fluorescent lamp 7. The socket cover 8 can be removed by pulling the cover 8 in the opposite direction to the mounting direction.

[0009]

The socket cover 8 provided in the luminaire having the above-mentioned structure has the screw receiving boss 13 as the necessary structure for screwing the holding spring 10 in the body 9 thereof. In addition to being projected on the head, the fluorescent lamp 7 is attached to the head of the screw 11 screwed therewith.
Since it is necessary to prevent it from hitting, the outer bottom surface of the socket cover 8 and the fluorescent lamp 7 in the mounted state.
A large clearance C (see FIG. 8) between and must be secured. That is, the step formed by the fluorescent lamp 7 and the socket cover 8 is large, which may hurt the appearance of the device.

Since the space C is ensured, the body 9 is tall and the material cost thereof is high, and the screw 11 is used. Therefore, the number of parts of the socket cover 8 and the number of assembling steps are increased. However, there is also a problem that the cost is high.

Moreover, the socket cover 8 is detached each time the lamp is replaced, but if the screw 11 is not properly tightened, the screw 11 loosens as the socket cover 8 is detached, and the socket cover 8 is not prepared. It is possible that it may fall into the area.

Further, since the slanted portion 10a which is the free end of the holding spring 10 is short and can move so as to spread outward with the screwed portion as a fulcrum, when the socket cover 8 is mounted, the slanted portion 10a is fixed to the fluorescent lamp 7. On the other hand, the action of guiding the socket cover 8 to a proper position is low. Moreover, when the socket cover 8 is attached, the position of the slanted portion 10a with respect to the fluorescent lamp 7 is difficult to determine, so that the direction of the load applied to the slanted portion 10a by contact with the fluorescent lamp 7 is constant. Instead, for example, a large amount of load is concentrated on one of the inclined portions 10a and only one side of the holding spring 10 is excessively deformed, so that the behavior of the holding spring 10 is likely to be unstable. As a result, it is conceivable that the excessively deformed side may generate excessive stress and the spring property of the holding spring 10 may be impaired.

Therefore, the first problem to be solved by the present invention is that the appearance of the device can be improved, the socket cover can be easily attached, and the attached socket cover is not likely to drop. To provide various lighting equipment.

A second problem to be solved by the present invention is to realize the first problem, so that the socket cover can be attached more easily and the side wall of the socket cover is prevented from being deformed. Another object of the present invention is to provide a lighting fixture that can be mounted in a good appearance.

Spring facing portions facing each other with a separation distance wider than the lamp diameter are provided on the facing side wall inner surfaces, and the tip ends of the pair of lamp holding portions are engaged with these spring receiving portions, respectively, and from the tip ends to the central bent portion. The inclined portion of the crossing lamp clamping portion is arranged so as to face the open surface of the body on the appliance body side, and the spring central portion is brought close to the bottom of the body, The lifting spring in which was placed in the body.

In the present invention, the socket cover for housing the end portion of the fluorescent lamp and the lamp socket holds the mounted state by elastically clamping the fluorescent lamp by the pair of lamp clamping portions of the retaining spring. . In such socket cover installation work, the slanted portion of the lamp holding portion serves as a guide for properly guiding the fluorescent lamp between the pair of lamp holding portions, and the tips of these slanted portions are provided on both side walls of the body. Since it is engaged with the spring receiving portion, its guide length can be increased. Moreover, since the holding spring is supported at both ends by the spring receiving portions as described above, only one of the lamp holding portions is not excessively deformed by the force received from the fluorescent lamp when the socket cover is attached, and the holding spring is held. The behavior of the spring can be stabilized. Further, since the holding springs are arranged inside the body by engaging the tips of the pair of lamp holding parts with the spring receiving parts of the body, the socket cover can be assembled without screwing, and the screw receiving There is no need to install a boss on the body. Thereby, the height of the body can be reduced, and the bottom of the body can be brought close to the end of the fluorescent lamp.

It has an L shape. These spring receiving portions 35 are opposed to each other in the width direction of the body 32 with a separation distance F wider than the lamp diameter E of the fluorescent lamp 26.

The holding spring 33 is formed by bending a strip-shaped plate spring. As shown in FIG. 3C, the holding spring 33 has a pair of V-shaped lamp holding portions 36 and the holding portions 36.
It is composed of a spring central portion 37 that is integrally connected to each other. The pair of lamp sandwiching portions 36 are arranged so as to face each other with the central curved portions 36a of the lamp clamping portions 36 closest to each other, and the distance G between the central curved portions 36a is set smaller than the lamp diameter E. The spring central portion 37 is bent in an arc shape according to the shape of the bottom portion of the body 32.

The holding spring 33 has a lamp holding portion 3
The tip end 36b of 6 is abutted against the inside of the corner formed by the side wall 32a and the hooking wall 35a of the spring receiving portion 35, and the arc-shaped boundary portion 33a formed by the lamp holding portion 36 and the spring central portion 37 is formed on the side wall. 32a is brought into contact with the inner surface,
It is housed and arranged in the spring housing space without being screwed. In this mounted state, the lamp holding portion 36
Is in a slightly elastically deformed state, whereby the holding spring 33 is attached to the body 32 without rattling.

Then, as shown in FIG. 3 (B), at the tip 36b side of the slanted portions 36c of both lamp holding portions 36,
The notches 38 are provided from both sides in the width direction, whereby the cross-sectional areas of the small cross-sectional area portions 39 between the notches 38 are made smaller than the cross-sectional areas of the other portions. As a means for providing such a difference in cross-sectional area, in the present invention, one or more small holes may be provided instead of the notch, and a groove extending over the entire width direction may be provided to partially reduce the thickness. Good.

The holding spring 33 held in the spring accommodating space by engaging the tip 36b of the lamp holding portion 36 with the spring receiving portion 35 as described above is provided by being inserted from the one end open surface 31a. The insertion depth is regulated by the engagement of the spring receiving portion 35 with the stopper wall 35b.
Then, the inclined portions 36c extending from the tips 36b of the pair of lamp holding portions 36 of the holding spring 33 thus mounted to the central curved portion 36a face the upper end open surface 31b, respectively, and the spring central portion 37 is It is close to the bottom of the body 32. A gap between the spring central portion 37 and the bottom portion of the body 32 is ensured to facilitate elastic deformation of the holding spring 33.

The socket cover 31 having such a structure is attached by exposing the upper end open surface 31b to the end portion of the fluorescent lamp 26 and the lamp socket 25 supporting this end portion and covering them. An arrow in FIG. 4A indicates a mounting direction of the socket cover 31.

In this attachment, first the holding spring 3
Since the slanted portions 36c of the pair of lamp clamping portions 36 of No. 3 correspond to the end portions of the fluorescent lamp 26, the lamp clamping portion 36 of the holding spring 33 is elastically deformed, and the central bent portion 36 thereof is formed.
It is pushed open by the fluorescent lamp 26 so that the space a is opened. The lower half of the end of the fluorescent lamp 26 is located at the central bent portion 36.
At the same time as overcoming a, the lamp holding portion 36 tries to rapidly restore to the original free state.
After going through the state shown in FIG.
6 elastically clamps the end portion of the fluorescent lamp 26 from both sides in the radial direction. As a result, the socket cover 31 accommodates the end portion of the fluorescent lamp 26 and the lamp socket 25 therein, and is attached and held to the fluorescent lamp 26. This mounted state is shown in FIG. To remove the socket cover 31 for lamp replacement or the like, the holding spring 33 can be elastically deformed and removed by pulling the cover 31 in the direction opposite to the mounting direction.

By the way, in the work of mounting the socket cover 31, the inclined portions 3 of the pair of lamp holding portions 36 are provided.
6c is a fluorescent lamp 26 between these lamp holding portions 36.
It is used as a guide to guide properly.

In this case, the tips 3 of these oblique portions 36c
6b is a spring receiving portion 3 provided on both side walls 32a of the body 32.
The guide length is large because it is abutted against and engaged with the lower side of the guide 5. Moreover, as described above, since the holding spring 33 is supported at both ends by the engagement with the spring receiving portion 35, one of the lamp holding portions 36 due to the force received from the fluorescent lamp 26 when the socket cover 31 is attached. It is possible to stabilize the behavior of the holding spring 33 without excessively deforming only the holding spring 33. Therefore, for these reasons, the socket cover 31 can be easily attached.

As described above, since the holding spring 33 is arranged in the body 32 by engaging the tips 36b of the pair of lamp holding portions 36 with the spring receiving portion 35 of the body 32, the holding spring 33 is screwed. The socket cover 31 can be assembled without any trouble. Accordingly, it is not necessary to provide the screw receiving boss on the inner bottom portion of the body 32. Therefore, the height of the screw receiving boss and the height of the head of the screw protruding from the screw receiving boss are larger than those of the conventional body having the screw receiving boss. Accordingly, the height of the body 32 can be reduced.

Therefore, in addition to reducing the material cost by downsizing the body 32, the number of parts of the socket cover 31 and the number of assembling steps can be reduced by not using screws. Therefore, the socket cover 31 can be obtained at low cost, and the cost of the lighting fixture including the socket cover 31 can be reduced.

Moreover, as described above, the socket cover 31
Since the height of the fluorescent lamp 26 can be lowered, the bottom of the body 32 can be covered with the fluorescent lamp 26 when the socket cover 31 is mounted.
Can be brought close to the edge of. Therefore, the end portion of the fluorescent lamp 26 and the socket cover 31 attached to the end portion
The step formed by and (the height is shown by symbol H in FIG. 2) is reduced, and the appearance of the device can be improved.

Further, as described above, the socket cover 31
Since only one of the lamp holding portions 36 is not excessively deformed by the force received from the fluorescent lamp 26 when mounting, the holding spring 33 is caused by such excessive deformation.
Does not impair the elasticity. Further, as described above, since the holding spring 33 is fixed without being screwed, there is no problem associated with loosening of the screw, and the holding spring 3
There is no risk that the connection between the body 32 and the holding spring 33 will be inadvertently released due to the engagement between the both ends 36b of 3 and the spring receiving portion 35. Therefore, for these reasons, it is possible to prevent the socket cover 31 from being accidentally dropped.

Further, since the notch 38 is provided in the slanted portion 36c, the behavior of elastic deformation of the lamp holding portion 36 when the socket cover 31 is mounted is mainly centered on the small cross-sectional area portion 39 between the notches 38. Done as. The state is shown in FIG. Therefore, although the holding spring 33 is supported at both ends, the pair of lamp holding portions 36 of the holding spring 33 can be easily elastically deformed when the socket cover 31 is mounted, so that the socket cover 31 can be more easily opened. Can be installed.

In addition, since the elastic deformation centering on the small cross-sectional area portion 39 sandwiched by the notches 38 is maintained as shown in FIG. 2 even after the socket cover 31 is attached, a pair of lamps is provided. Even when the holding portion 36 holds the fluorescent lamp 26, the holding spring 33 holds the side wall 3 of the body 32.
The force pushing 2a outward is small. Therefore, the socket cover 31 is not deformed and attached so that the one end open surface 31a side is opened. As a result, the reflector 2 on the side wall 32a of the mounted socket cover 31 is
The edges contacting 3 are the bottom wall 23a and the sloping wall 23b of the reflection plate 23.
Since it can be provided in parallel along the line of the corner 23c extending in the longitudinal direction at the boundary with, the socket cover 31 can be attached in a good appearance.

FIG. 5 shows a second embodiment of the present invention. The second embodiment is different from the first embodiment only in the structure of the tip of the lamp holding part and the structure of the spring receiving part with which the lamp holding part is engaged, and the other structures are the same as those in FIG.
1 to 4 are the same as or similar to the luminaire of the first embodiment shown in FIGS. 1 to 4 including parts not shown in FIG. The same or similar components as those described above are designated by the same reference numerals as those in the first embodiment, and the description of those components and the description of the action and effect based thereon will be omitted, but these same or similar components Also, it constitutes a part of the configuration of the lighting fixture according to the second embodiment.

In the second embodiment, the tip ends 36b of the pair of lamp holding portions 36 are bent into a substantially L shape, and the tip walls 36a of the pair of spring receiving portions 35 are pulled by the tip ends 36b. Engagement groove 3 having a substantially L-shape that is hooked and engaged
5c is provided. Then, the substantially L-shaped tip 36b
Is also engaged with a substantially L-shaped engagement groove 35c. In FIG. 5, the chain double-dashed line shows a state in which the lamp holding portion 35 is elastically deformed around the notch 38 due to the notch 38 in the socket cover mounting operation as in FIG. 4B. The configuration other than these points is the same as that of the first embodiment.

Therefore, also in the second embodiment, the same effect as that of the first embodiment can be obtained and the problem of the present invention can be solved. Further, in the second embodiment, since the tip end 36b of the lamp holding portion 36 is hooked on the engagement groove 35c of the spring receiving portion 35 to support the holding spring 33, a boundary portion of the holding spring 33 is provided. 33a
(Not shown in FIG. 5) does not necessarily have to contact the inner surface of the side wall 32a of the body 32.

[0042]

According to the present invention described in detail above, the following effects are obtained.

According to the lighting equipment of the first aspect of the present invention,
Since the body of the socket cover and the holding spring are assembled by omitting the screw receiving boss and the screw screwed to the screw receiving boss, which are conventionally required, the height of the body can be reduced and the bottom of the body can be used as the end of the fluorescent lamp. Therefore, the step formed between the end of the fluorescent lamp and the socket cover attached to the fluorescent lamp can be reduced, and the appearance of the device can be improved. Further, in combination with the downsizing of the body, a screw for fixing the holding screw is unnecessary, so that the cost of the socket cover can be reduced and the device can be obtained at low cost.
Further, since the function of guiding the lamp is improved by the inclined portions of the pair of lamp holding portions of the holding spring supported at both ends, the socket cover can be easily attached. In addition, as described above, coupled with the fact that the holding screw is not used, the behavior of the holding spring when the socket cover is attached is stable, and the elasticity of the holding spring is less likely to be impaired. You can eliminate the risk of falling easily.

According to the lighting equipment of the invention of claim 2,
Although the holding spring is supported at both ends, the holding spring is easily elastically deformed when the socket cover is attached, so that the socket cover can be attached more easily. Moreover, since the holding spring has a small force to push the side wall of the body outward while the lamp holding portion holds the fluorescent lamp, the socket cover may be deformed and attached so that the opening side thereof is opened at one end. It's gone and you can attach the socket cover in good shape.
