As a result, the tongue pieces 46a and 46b are caught by the notches 47a and 47b, and the bracket 37a is positioned in the longitudinal direction of the reflection plate 22. As a result, the bracket 37a is immovably held on the back surface 36 of the reflection plate 22.

The first and second tongue pieces 46a, 46b
If the notches 47a and 47b where the brackets 37 are caught are arranged more widely at intervals in the longitudinal direction of the reflector 22, the mounting positions of the brackets 37a and 37b can be shifted stepwise along the longitudinal direction of the reflector 22. . For this reason, the position of the stabilizer 38 can be freely adjusted according to the positions of the stabilizer 9 and the terminal block 8 of the existing chassis 3.

The stabilizer 38 includes brackets 37a and 37b.
Are arranged over the vehicle. The ballast 38 is an inverter-type electronic ballast corresponding to the fluorescent lamp 32 dedicated to high-frequency lighting, and has an elongated shape extending in the longitudinal direction of the reflector 22. The ballast 38 has both ends 38a, 38b along its longitudinal direction with brackets 37a, 3b.

Next, the procedure for updating the existing lighting fixture 1 installed on the ceiling 2 will be described.

First, after removing the fluorescent lamp 6 from the existing lighting fixture 1, the decorative screw 16 is loosened and the reflecting plate 11 is removed to expose the chassis 3. Next, the lamp socket 5 is removed from the socket fittings 4a and 4b of the chassis 3 so that the chassis 3 remains on the ceiling 2. At this time, the terminal block 8 and the ballast 9 are left without being removed from the chassis 3.

Next, a new lighting fixture 21 is installed on the ceiling 2 using the existing chassis 3. This lighting fixture 21
Prior to the installation of the ballast, the reflector 38 of the lighting fixture 21 is previously attached to the stabilizer 38 via the brackets 37a and 37b.
In addition, a terminal block 51 is mounted, and a lamp socket 29 is fitted into the socket mounting holes 28a and 28b of the reflection plate 22. Further, the output end of the terminal block 51 and the lamp socket 29 are electrically connected via a lead wire. Bracket 3 to this reflector 22
The work of assembling the 7a and 37b, the stabilizer 38, the terminal block 51, and the lamp socket 29 and the work of electrically connecting them are performed in a factory or a construction site.

And is temporarily fixed to the chassis 3. By this temporary fixing, the positional relationship between the chassis 3 and the reflection plate 22 is kept constant even when the hand is released from the reflection plate 22, so that the electrical connection between the terminal block 51 and the power supply is performed at this time.

Therefore, the troublesome work of making an electrical connection while supporting the reflection plate 22 with one hand is released.
Connection work between the terminal block 51 and the power supply can be concentrated and efficiently performed.

Next, the reflection plate 22 is pushed up toward the chassis 3 of the ceiling 2 and the through holes 33a, 33 at both ends of the reflection plate 22 are formed.
3b is aligned with the screw hole 15 of the chassis 3. And
A decorative screw 34 is passed through the through holes 33a and 33b from below, and the decorative screw 34 is screwed into the screw hole 15.
As a result, the reflection plate 22 is fixed to the existing chassis 3, and the chassis 3 is covered and hidden by the light reflection portions 23 a and 23 b and the end plate portions 24 a and 24 b of the reflection plate 22.

At this time, the old terminal block 8 and the ballast 9 are left as they are at the center along the longitudinal direction of the chassis 3, but the ballast 38 and the terminal block 51 incorporated in the new reflector 22 are left. Is installed at a position deviated to one side along the longitudinal direction from the center of the reflection plate 22. For this reason, when the reflection plate 22 is pushed up toward the chassis 3,

Finally, by installing the fluorescent lamp 32 between the lamp sockets 29, the aging existing luminaire 1 shown in FIG. 7 is replaced with a new luminaire 21 shown in FIG.

According to the lighting fixture 21 thus updated, the reflector plate 22 incorporating various electric components such as the ballast 38 is utilized by utilizing the existing chassis 3 left on the ceiling 2. Can be installed. For this reason, when updating the aging lighting fixture 1, the chassis 3 can be left as it is without removing it from the ceiling 2,
The troublesome work of removing the chassis 3 becomes unnecessary.

In addition, the new ballast 38 and terminal block 51
Is installed at a position avoiding the old ballast 9 and the terminal block 8 left on the chassis 3, so that the old ballast 9 and the terminal block 8 may not interfere with the assembly of the reflector 22. No problem occurs even if it is left on the ceiling 2 together with the chassis 3.

The ballast 38, the terminal block 51 and the lamp socket 29 are also supported by the reflection plate 22.
A dedicated component for fixing these electric components to the chassis 3 becomes unnecessary.

Therefore, when the aging lighting fixture 1 is renewed, the number of new and old parts which need to be detached and the number of man-hours required for detaching can be greatly reduced. The removal work and the work of attaching a new lighting fixture 21 to the ceiling 2 can be performed easily and easily, and the cost of updating the lighting fixture 1 to the lighting fixture 21 can be reduced.

The existing chassis 3 is reused as a support member for the reflection plate 22 and the old ballast 9 and the terminal block 8 are also left on the ceiling 2 together with the chassis 3. In comparison with the related art in which the components of (1) are disposed of, it is possible to reduce the amount of waste generated at the time of renewal. For this reason, the cost required for waste disposal can be kept low, and there is no trouble in processing this waste.

Further, the existing chassis 3, terminal block 8 and stabilizer 9 are covered from outside by a new reflector 22, so that the old chassis 3 is reused as a support member for the reflector 22. However, the appearance of the lighting fixture 21 becomes the same as a new article, and there is no problem in appearance.

In addition, the updated luminaire 21 has a fluorescent lamp 32 dedicated to high-frequency lighting, and this fluorescent lamp 32 is lit using an inverter-type ballast 38. Compared with a lighting device using a ballast, power saving can be realized while increasing the floor illuminance.

Further, according to the above configuration, the brackets 37a and 37b supporting the ballast 38 have the first and second locking pieces 43 and 44 at both ends along the width direction of the brackets 37a and 37b. By being hooked on 25b, it is immovably fixed to the reflection plate 22. For this reason, when fixing the brackets 37a and 37b to the reflection plate 22, special screws and troublesome welding work can be omitted, and these brackets 37a and 37b can be easily incorporated into the reflection plate 22. . At the same time, the reflection plate 22
The head of the screw and the welding trace are not exposed on the upper side, and the external appearance of the reflector 22 and thus the lighting fixture 21 can be favorably maintained. Also, the support portions 40 of the brackets 37a, 37b
The new ballast 38 and the screw 49 for mounting the terminal block 51 mounted thereon abut on the new reflection plate 22 and do not deform the reflection plate 22.

The second embodiment is different from the first embodiment in that the ballast 38 is slidably mounted along the longitudinal direction of the reflector 22. The configuration is the same as that of the first embodiment. Therefore, in the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIGS. 10 and 11, the support portions 40 of the brackets 37a and 37b are formed with screw insertion holes 61 through which screws 49 are passed. Screw insertion hole 61
Has a slit 62 and a large-diameter portion 63 connected to one end of the slit 62. The slit 62 is provided in the reflector 2

It has a larger diameter than b.

The screw insertion hole 6 of the bracket 37a
The large-diameter portion 63 of the bracket 1 and the screw insertion hole 61 of the bracket 37b is located on the opposite side of the slit 62.

In such a configuration, when the nut 50 is loosened and the tightening of both ends 38a and 38b of the ballast 38 is released, the ballast 3 is fixed within the length L of the slit 62.
8 can be freely slid in the longitudinal direction of the reflection plate 22. Therefore, when the terminal block 8 and the ballast 9 are left on the existing chassis 3 directly attached to the ceiling 2, the ballast 38 is slid in advance to a position where the terminal block 8 and the ballast 9 are avoided. By doing so, the existing terminal block 8 and stabilizer 9 do not hinder the assembly of the reflector 22 into the chassis 3.

Therefore, the reflection plate 22 can be incorporated into the chassis 3 without being affected by the size and position of the existing terminal block 8 and ballast 9, and the workability when updating the lighting fixture 21 is improved. be able to.

The oblique portion 114a is provided with the light reflecting portions 23a, 2a of the reflecting plate 22.
The light reflecting portions 23a and 23b are inclined so as to be substantially equal to the inclination of the light reflecting portions 3b.
In addition, the convex edge 114 b is formed by the curling portion 25 of the reflection plate 22.
a and 25b can be inserted and removed as needed, and can be used to hook and support the reflection plate 22 by the insertion.

That is, while the adapter main body 102 is hooked on the existing chassis 3 and the restricting body 103 is attached to the main body 102, one of the reflector receiving portions 1 is provided.
For example, by hooking one curling portion 25a on the 14 protruding edge 114b as shown by a two-dot chain line in FIG. 16, the reflecting plate 22 can be temporarily fixed in an open state via a pair of adapters 101. In this state, it is possible to release the hand from the reflection plate 22 and efficiently connect the power supply and the like. In addition, such a construction mode can be selectively performed instead of temporarily fixing the reflection plate 22 by the string 52.

And the screw shaft of the decorative screw 34 is formed to pass through a through hole 33 formed therethrough.

Further, a ballast 38 as a new lighting device is attached to the reflection plate 22 on the back surface 36 of one of the light reflection portions 23a so as to avoid the old ballast 9 of the existing chassis 3. A cord 117 having a connector 116 at the tip thereof to which a power supply line (not shown) is connected is drawn from the ballast 38. Therefore, this lighting fixture 21
Does not have a new power supply terminal block. The configuration other than the above is the same as that of the first embodiment.

Next, a description will be given of a procedure for updating and attaching the lighting fixture 21 of the fourth embodiment to the chassis 3 from which the reflector and the lamp socket of the existing lighting fixture 1 have been removed.

First, the adapter body 102 is hooked and attached at two longitudinal positions of the chassis 3 so as to hold the adapter body 102, respectively. In this case, as described above, the adapter body 102 can be hooked so as to be fitted by utilizing the elastic deformation thereof, or can be fitted at both ends in the longitudinal direction of the existing chassis 3 and moved in the longitudinal direction of the chassis 3. It can also be provided.
Next, each of the adapter bodies 102 is
3 and the adapter 101 is assembled. Restraint 1
03 is assembled by fitting the notch grooves 106, 111 (or 112) into each other.

Next, using the string 52 extending between the adapter main body 102 and the existing chassis 3, or using the convex edge 114 b of one of the reflector receiving portions 114 of the pair of restraining members 103.
By temporarily hooking one of the curling portions 25a of the reflection plate 22, the reflection plate 22 is temporarily fixed in an open state, and in this state, necessary electrical connection is performed using the connector 117 or the like.

Thereafter, if necessary, the engagement between the convex edge 114b and the curling portion 25a is released, and the reflection plate 22 is pushed up toward the chassis 3 of the ceiling 2 so that the both end plates 24
The through holes 33 near a and b are matched with the screw clips 104 of the adapter body 102. Then, a decorative screw 34 is passed through the through hole 33 from below, and the decorative screw 34
Is inserted between the pair of holding pieces of the screwing clip 104 with one touch, and then the decorative screw 34 is screwed in as necessary. As a result, the reflection plate 22 is fixed to the existing chassis 3, and the chassis 3 is covered and hidden by the light reflection portions 23 a and 23 b and the end plate portions 24 a and 24 b of the reflection plate 22. In this case, the decorative screw 3 required for mounting the reflector 22
4 can be pushed in with one touch, so that the work is extremely easy.

At this time, the old terminal block and the ballast 9 are left as they are in the central part along the longitudinal direction of the chassis 3, but the ballast 38 and the terminal block 51 incorporated in the new reflector 22 are The reflector 22 is provided so as to be deviated to one side in the width direction from the center of the reflector 22 and is provided at a position retracted in advance so as not to interfere with the existing stabilizer 9 or the like. Therefore, when the reflection plate 22 is pushed up toward the chassis 3, the new ballast 38 does not interfere with the existing old ballast 9 or terminal block.

Finally, by installing the fluorescent lamp 32 between the lamp sockets 29, the aging existing luminaire 1 is updated to a new luminaire 21. Therefore, also in the present embodiment, the same effect as in the first embodiment can be obtained to solve the problem of the present invention.

That is, according to the lighting fixture 21 which is updated as described above, the existing chassis 3 left on the ceiling 2 is used to incorporate various electric components such as the ballast 38 into the reflector 21. A plate 22 can be provided. For this reason, when the aging lighting fixture 1 is renewed, the chassis 3 can be left as it is without removing it from the ceiling 2, and the troublesome work of removing the chassis 3 becomes unnecessary. Moreover, since the new ballast 38 is installed at a position avoiding the old ballast 9 and the terminal block left on the chassis 3, the old ballast 9 and the terminal block 8 hinder the assembling of the reflector 22. There is no problem even if it is left on the ceiling 2 together with the chassis 3. or,
The reflection plate 22 is used for the ballast 38 and the lamp socket 29.
, There is no need for a dedicated component for fixing these electrical components to the chassis 3.

Therefore, when replacing the deteriorated lighting equipment 1, the number of new and old parts which need to be detached and the number of man-hours required for detachment can be greatly reduced. The removal work and the work of attaching a new lighting fixture 21 to the ceiling 2 can be performed easily and easily, and the cost of updating the lighting fixture 1 to the lighting fixture 21 can be reduced.

Further, the existing chassis 3 is reused as a support member for the reflection plate 22, and the old ballast 9 and the terminal block are also left on the ceiling 2 together with the chassis 3, so that all of the existing lighting fixtures 1 are provided. Compared with the related art in which components are disposed of, waste generated at the time of renewal can be reduced. For this reason, the cost required for waste disposal can be kept low, and there is no trouble in processing this waste.

Further, the existing chassis 3, terminal block 8 and stabilizer 9 are covered from outside by a new reflector 22, so that the old chassis 3 is reused as a support member for the reflector 22. However, the appearance of the lighting fixture 21 becomes the same as a new article, and there is no problem in appearance. In addition, the updated luminaire 21 includes a fluorescent lamp 32 dedicated to high-frequency lighting, and the fluorescent lamp 32 is lit using the inverter type ballast 38. Compared with the lighting equipment used, it is possible to realize power saving while increasing the floor illuminance.

In the above mounting, when the reflecting plate 22 is pushed up toward the ceiling 2, the curling portion 25
Immediately before the a and 25b contact the ceiling 2, the back surfaces of the light reflecting portions 23a and 23b of the reflecting plate 22 contact the inclined portions 114a of the two reflecting plate receiving portions 114 which are substantially equidistant from the center of the restricting body 103. . In this case, since the reflecting plate 22 is inclined in the one-sided contact state, it is easy to know that the reflecting plate 22 is not in an appropriate posture. The reflecting plate 22 can be set in an appropriate mounting posture by hitting each of the inclined portions 114a of the portion 114. Thereby, the restraint 1
Since the through holes 33 of the reflector 22 can be aligned with the screw clips 104 of the adapter body 102 through the holes 03, the decorative screws 34 can be easily inserted into the screw clips 104 to mount the reflector 22. Can be performed, and workability can be improved.

In the updated state shown in FIG. 16, the restricting body 103 is attached to the adapter main body 102, and the stopper portions 103a of the restricting body 103 respectively contact the outer surfaces of both side walls 102c of the adapter main body 102. To prevent a large opening between both side walls 102c of the adapter body 102. Therefore, even if a strong vibration is applied in the event of an earthquake or the like, it is possible to eliminate the possibility that the adapter 103 is inadvertently detached from the existing chassis 3 and the reflector 22 falls off.

Further, in the fourth embodiment, after the adapter 102 is attached to the existing chassis 3, the reflection plate 22 covering the chassis 3 is moved to the decorative screw 34 passing through the center in the width direction.
The size of the adapter 102 is selected so that it can be commonly mounted on each of the chassis 3 in the existing lighting fixtures of different models since the configuration is such that the adapter 102 is screwed to the screwing clip 104 of the adapter 102 using As a result, the screw 1
04 and the position of the through hole 33 of the reflection plate 22 which is screwed to the clip 104 and through which the decorative screw 34 passes can be standardized. Therefore, the present invention is suitable for a case where a different kind of existing lighting equipment is replaced with a new lighting equipment.

The interval A between the sockets 25a and 225b is slightly larger than the interval B between the socket fittings 4a and 4b which are attached to both ends of the old chassis 3 in the longitudinal direction so as to face each other in the width direction. Generally, the socket mounting brackets 4a and 4b are mounted with their upper ends hooked on the upper wall 3a of the chassis 3, and the socket mounting brackets 4a and 4b can be moved slightly in the direction away from the side walls 3b and 3c of the chassis 3 using the mounting portion as a fulcrum. Things. Then, the socket holder 225 is densely inserted from below so as to press against the opposing surfaces of the opposing socket mounting brackets 4a, 4b while elastically deforming the peripheral wall pieces 225a, 225b, and is released by the close contact force. It has been stopped.

The configuration other than the above is the same as that of the first embodiment. Therefore, the existing lighting fixture 1 that has been deteriorated in the same procedure as in the first embodiment can be replaced with a new lighting fixture by reusing the existing chassis 3 without discarding all the components. Therefore, in this embodiment, the same effect as in the first embodiment can be obtained, and the problem of the present invention can be solved.

Since the lamp socket 6a detached between the chassis 3 and the new reflection plate 222 is held by closely inserting the lamp socket 6a between the chassis 3 and the new reflector 222, the socket holder 225 is provided.
Thereby, the socket fixtures 4a and 4b facing each other in the width direction of the chassis 3 can be stretched from between each other. Accordingly, the socket mounting brackets 4a and 4b can be held stationary so as not to be inadvertently moved, so that there is no possibility that the socket mounting brackets 4a and 4b move and hit the chassis 3 or the like to generate noise. I can do this.

In each of the above embodiments, the cross-sectional shape of the peripheral portion of the reflector in contact with the ceiling, in particular, the curling portion of the light reflecting portion, such as a C-shape or an R-shape, becomes closer to the ceiling. A rounded shape that is gradually displaced inward can be provided. This is preferable in that the gap between the ceiling and the peripheral edge of the reflector can be hardly distinguished in appearance.
