Description

Embodiments of the present invention relate to a lighting device for renewing an existing lighting device and a method for renewing the same.

Conventionally, configurations and renewal methods have been proposed for replacing existing light sources such as fluorescent lamps arranged in existing lighting devices with new light source units using LEDs or the like. In this renewal method, the existing light source is removed from between the sockets, the mounting bracket is processed and attached to the reflector, and the light source unit is attached to the mounting bracket.

However, it is necessary to process and install mounting brackets to attach the light source unit to the reflector, and depending on the type of lighting device, even if you try to replace the existing light source with the light source unit, the existing mounting structure of the reflector may be a problem. This may make it difficult to attach the light source unit.

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

Next, a renewal method for replacing the existing lighting device 10 with a lighting device 40 that uses the reflector 41 and the light source section 42 will be described.

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

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

Note that the condition of the exposed existing appliance main body 14 is checked, and if it is confirmed that there are no defects, the following renewal work will be continued.

Subsequently, the socket 17 is removed from the socket mounting member 21. Note that the socket attachment member 21 to which the socket 17 is attached may be removed from the existing instrument body 14.

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

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

Next, the fixture 30 is attached to the attachment hole 28 of the fixing member 22 from the inside of the reflection plate 41 through the insertion hole 50 of the reflection plate 41. The reflector 41 is fastened to the fixing member 22 of the existing appliance main body 14 using the fixture 30, and the reflector 41 is attached so that the decorative frame portion 49 is in contact with the lower surface side of the ceiling board.

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

Next, the mounting spring 73 of the light source unit 57 is hooked onto the spring holder 58 of the chassis 56 fixed to the reflection plate 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 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 attachment spring 73. This completes the renewal of the lighting device 40.

In this lighting device 40, by leaving and using the existing fixture main body 14 of the existing lighting device 10, the existing reflector 15 and the existing light source 16 are replaced with the reflector 41 and light source section 42 for renewal. There is no need for special processing, construction can be reduced, the appearance is good, and the existing lighting device 10 can be easily renewed.

In addition, since the reflector plate 41 is thin, distortion easily occurs, but by fixing the chassis 56 of the light source section 42 to the reflector plate 41, the rigidity of the reflector plate 41 is improved, and the reflection plate is Distortion of the plate 41 can be reduced. Furthermore, by attaching the back side of the reflector 41 to the existing appliance main body 14, distortion of the reflector 41 after installation can be reduced.

Furthermore, 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, in addition to having a good appearance, the reflector 41 is arranged in a shape suitable for the light source part 42. It is also possible to adjust the lighting appropriately.

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

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

Furthermore, by arranging the power supply unit 59 on the chassis 56 of the light source section 42, the power supply unit 59 does not interfere with the existing fixture body 14 side, and it is possible to construct the lighting device 40 using the existing fixture body 14. becomes.

In addition, during renewal work, when the existing reflector 15 is removed and the condition of the existing fixture main body 14 is checked, if it is confirmed that there is a problem, the use of the existing fixture main body 14 is discontinued, and the existing fixture main body 14 is replaced. The main body 14 is removed from the hanging bolt 11, and the reflecting plate 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 reflecting plate 41 arranged on the ceiling board, a hanging bolt adjustment work is performed to extend the length of the hanging bolt 11 or replace it with a longer 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 below the chassis 56, insert the upper side of the reflector 41 into the hole in the ceiling plate, and then The suspension bolt 11 is passed through the suspension bolt attachment hole 66 of the chassis 56 through the opening 52 of the plate 41, and the washer 23 and nut 24 are attached to the suspension bolt 11. The reflector 41 is tightened with 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 board.

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 reflection plate 41 can be attached to the suspension bolt 11 by using the suspension bolt attachment hole 66 of the chassis 56 of the light source section 42, and the reflection plate 41 has the suspension bolt attachment hole 66 of the chassis 56. By providing the opening 52 in the chassis 56, the suspension bolt attachment hole 66 of the chassis 56 can be effectively utilized.

In addition, even if the existing fixture body 14 cannot be used during renewal work, it is possible to install a reflector 41 and light source unit 42 that have the same shape as the reflector plate 41 and light source unit 42 that use the existing fixture body 14. For example, the appearance of a plurality of lighting devices 40 installed on the same floor can be unified.
