Description

An embodiment of the present invention relates to a lighting device for renewing an existing lighting device and a method for renewing the lighting device.

Conventionally, a configuration and a renewal method for replacing an existing light source such as a fluorescent lamp arranged in an existing lighting device with a new light source unit using an LED or the like have been proposed. In this renewal method, the existing light source is removed from between the sockets, the mounting bracket is processed and mounted on the reflector, and the light source unit is mounted on the mounting bracket.

However, it is necessary to process and mount the mounting bracket for mounting the light source unit on the reflector, and depending on the type of lighting device, even if the existing light source is replaced with the light source unit, the existing mounting structure of the reflector will be an obstacle. Therefore, it may be difficult to attach the light source unit.

Further, simply replacing the existing light source with a light source unit may impair the appearance.

Next, a renewal method of replacing the existing lighting device 10 with a lighting device 40 using the reflector 41 and the light source unit 42 will be described.

First, the existing light source 16 of the existing lighting device 10 is removed from between the sockets 17.

Subsequently, each fixture 30 is removed from the inside of the existing reflector 15, the existing reflector 15 is removed from the existing fixture main body 14, and the existing reflector 15 is removed from the embedding hole of the ceiling plate. As a result, the embedding hole of the ceiling plate is opened, and the existing appliance main body 14 arranged above the embedding hole is exposed.

The condition of the exposed existing instrument body 14 is checked, and if it is confirmed that there is no problem, the following renewal work is continued.

Subsequently, the socket 17 is removed from the socket mounting member 21. The socket mounting member 21 to which the socket 17 is mounted may be removed from the existing appliance main body 14.

Then, the power cable connected to the existing terminal block 19 of the existing appliance main body 14 is removed.

Subsequently, the removed power cable is passed under the chassis 56 through the opening 53 of the reflector 41 and the wiring hole 67 of the chassis 56, and then the upper side of the reflector 41 is inserted into the embedded hole of the ceiling plate.

Subsequently, from the inside of the reflector 41, the fixture 30 is attached to the attachment hole 28 of the fixing member 22 through the insertion hole 50 of the reflector 41. The reflector 41 is tightened to the fixing member 22 of the existing appliance main body 14 by the fixture 30, and the reflector 41 is attached in a state where the decorative frame portion 49 is in contact with the lower surface side of the ceiling plate.

Next, connect the power cable passed under the chassis 56 to the terminal block 60.

Subsequently, the mounting spring 73 of the light source unit 57 is hooked on the spring receiving metal fitting 58 of the chassis 56 fixed to the reflector 41. In this state, the light source unit 57 is suspended below the chassis 56 by the mounting spring 73, and there is a gap between the chassis 56 and the light source unit 57.

Subsequently, the output cable from the power supply unit 59 and the connection cable of the light source unit 57 are connected to the connector through the gap between the chassis 56 and the light source unit 57.

Subsequently, by pushing up the light source unit 57 toward the chassis 56, the light source unit 57 is pulled up and attached to the chassis 56 by the spring force of the mounting spring 73. This completes the renewal to the lighting device 40.

Then, in this lighting device 40, by using the existing fixture main body 14 of the existing lighting device 10 while leaving the existing fixture main body 14 at the time of renewal, the existing reflector 15 and the existing light source 16 are used as the renewal reflector 41 and the light source unit 42. It only needs to be replaced with, no special processing is required, construction can be saved, the appearance is good, and the existing lighting device 10 can be easily renewed.

Further, since the reflector 41 is thin, distortion is likely to occur. However, by fixing the chassis 56 of the light source unit 42 to the reflector 41, the rigidity of the reflector 41 is improved, and the reflection is reflected during the renewal work or after the construction. It is possible to reduce the occurrence of distortion in the plate 41. Further, since the back side of the reflector 41 is attached to the existing appliance main body 14, it is possible to reduce the distortion of the reflector 41 after construction.

Further, since the existing reflector 15 having the socket insertion hole 32 of the existing lighting device 10 is replaced with the reflector 41 for renewal, the appearance is good and the reflector 41 is arranged in a shape suitable for the light source portion 42. It is also possible to make the light etc. appropriate.

Furthermore, by using the existing equipment main body 14, it is possible to leave the existing power supply unit 18 and the existing terminal block 19 arranged in the existing equipment main body 14 as they are, so that when renewing, it is possible to leave them as they are. Only the existing reflector 15, the existing light source 16 and the socket 17 need to be recovered, and the amount of recovery is small, which is advantageous when renewing a large number of existing lighting devices 10 at a time.

Further, since the lighting fixture 55 having the chassis 56, the light source unit 57, the power supply unit 59, and the like is used for the light source unit 42, for example, an existing direct-mounted lighting fixture 55 called a base light can be used, and a reflector. It is only necessary to create a new 41, and the lighting device 40 for renewal can be configured at low cost.

Further, by arranging the power supply unit 59 in the chassis 56 of the light source unit 42, the power supply unit 59 does not interfere with the existing fixture main body 14, and the lighting device 40 using the existing fixture main body 14 can be installed. It becomes.

In addition, during the renewal work, when the existing reflector 15 was removed and the condition of the existing equipment body 14 was checked, if it was confirmed that there was a problem, the use of the existing equipment body 14 was stopped and the existing equipment was stopped. The main body 14 is removed from the hanging bolt 11, and the reflector 41 is directly attached to the hanging bolt 11 as shown in FIGS. 5 and 6.

In this case, depending on the height position of the reflector 41 arranged on the ceiling plate, the hanging bolt adjustment work is performed to extend the length of the hanging bolt 11 or replace it with a long hanging bolt 11.

After adjusting the hanging bolts, pass the power cable through the opening 53 of the reflector 41 and the wiring hole 67 of the chassis 56 under the chassis 56, insert the upper side of the reflector 41 into the embedded hole of the ceiling plate, and reflect. The suspension bolt 11 is passed through the suspension bolt mounting hole 66 of the chassis 56 through the opening 52 of the plate 41, and the washer 23 and the nut 24 are mounted on the suspension bolt 11. The reflector 41 is tightened by the nut 24 via the chassis 56, and the reflector 41 is attached so that the decorative frame portion 49 is in contact with the lower surface side of the ceiling plate.

After that, as described above, the power cable is connected to the terminal block 60, and the light source unit 57 is attached to the chassis 56.

In this way, the reflector 41 can be attached to the hanging bolt 11 by using the hanging bolt mounting hole 66 of the chassis 56 of the light source unit 42, and the reflector 41 has the hanging bolt mounting hole of the chassis 56. By providing the opening 52 with respect to 66, the suspension bolt mounting hole 66 of the chassis 56 can be effectively used.

Then, even if the existing fixture body 14 cannot be used during the renewal work, the reflector 41 and the light source portion 42 having the same shape as the reflector 41 and the light source portion 42 that use the existing fixture main body 14 can be installed. For example, the appearance of a plurality of lighting devices 40 installed on the same floor can be unified.

Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
