  The width TW of the illuminating device 1L is calculated by adding the width WA2 (170 mm) of the width of the two LED units 10 and the width of the one power supply unit 30 to the width (30 mm = 15 mm × 2) of the two side cover units 50B. This is a value (300 mm) obtained by adding the total value (130 mm) of the widths (100 mm = 25 mm × 4) of the four width adjustment joint units 60D. Thus, the adjustment of “+130 mm” is performed by the size adjustment unit 40 (here, two side cover units 50A and four width adjustment joint units 60D).

  As described above, in each of the lighting devices 1, in the width direction (X direction), a plurality of units including at least one light emitting unit, at least one power supply unit, and at least one size adjustment unit are arranged in combination. It is constituted by. According to this, it is possible to efficiently construct the lighting devices 1 of various widths.

  In particular, each lighting device 1 includes a plurality of illuminations having different widths at predetermined unit lengths ΔW, which are constructed by different combinations of a plurality of units including the LED unit 10, the power supply unit 30, and the size adjustment unit 40. It is constructed as a lighting device of one of the devices. More specifically, an appropriate size adjustment unit 40 is selected from a combination of a plurality of types of size adjustment units 40 corresponding to a plurality of widths different in increments of the predetermined unit width ΔW, and the size adjustment unit 40 is used. The lighting device 1 is constructed.

  For example, as shown in FIGS. 11 to 14, in a plurality of lighting devices 1 in which the combination of a predetermined number (here, two) of LED units 10 and a predetermined number (here, one) of power supply units 30 is the same. An appropriate unit among the plurality of size adjustment units 40 (side cover unit 50, width adjustment joint unit 60) is selected and used. In addition, an appropriate combination of the plurality of size adjustment units 40 realizes a plurality of different adjustment amounts in increments of a predetermined unit length ΔW (here, 10 mm). The plurality of size adjustment units 40 realize a plurality of different widths (and integral multiples of the predetermined unit length ΔW) in increments of a predetermined unit length ΔW (10 mm) within a predetermined range (20 mm to 130 mm).

  According to this, it is possible to efficiently construct a plurality of lighting devices having a plurality of widths different from each other by a predetermined unit width.

  In addition, in the plurality of lighting devices 1, the R-stage is determined by a combination of three types (P = 3) of side cover units 50 </ b> A, 50 </ b> B, 50 </ b> C and two types (Q = 2) of width adjustment joint units 60 </ b> B, 60 </ b> D. (However, the value R is a natural number, and the value of the width of R> P + Q) is realized. Note that the combination of the side cover unit 50 and the width adjustment joint unit 60 includes a configuration including only the side cover unit 50 (50A), such as the lighting device 1A (see the uppermost row in FIG. 11).

  Specifically, at least a value of the width in 12 steps (R = 12) in increments of a predetermined unit length ΔW (10 mm) is realized in the range of 20 mm to 130 mm. The total width WA2 (170 mm) of the width (here, 100 mm = 50 mm × 2) of the two LED units 10 arranged in the lighting device 1 and the width (here, 70 mm) of one power supply unit 30 is the designated width. The plurality of size adjustment units 40 are divided into a plurality of types of size adjustment units 40 (50A) such that the adjustment width WJ (20 mm to 130 mm) subtracted from the WD (190 mm to 300 mm) is equal to the total width of the plurality of size adjustment units 40. To 50C, 60B, 60D, etc.). Specifically, a value obtained by subtracting the total width WA of the units 10 and 30 arranged in the lighting device 1 from the specified width WD is the total width of the two side cover units 50 and the even number of the width adjustment joint units 60 (and , The type and the number of the width adjusting joint units 60 to be arranged in the lighting device 1 and the types of the two side cover units 50 are determined so as to be equal to any one of the width values of the R stage. Is done. Therefore, it is possible to realize the R-stage width (relatively multi-stage width) with a relatively small number of component types (P + Q) as compared with the case where the R-stage adjustment units are individually prepared. .

  As a result, the lighting device 1 adds various adjustment widths WJ (20 mm to 130 mm) by the size adjustment unit 40 to the total width WA2 (170 mm) of the two LED units 10 and one power supply unit 30. May be configured as devices having a plurality of different widths. That is, it is possible to easily configure a plurality of lighting devices 1 having different widths within a predetermined range (190 mm to 300 mm) at predetermined unit length ΔW (10 mm) intervals.

  Here, an example is shown in which a combination of three types of side cover units 50A to 50C and two types of width adjustment joint units 60B and 60D realizes 12 levels of adjustment values of “20 mm to 130 mm”. I have. However, according to the combination of the three types of side cover units 50A to 50C and the two types of width adjustment joint units 60B and 60D, more multi-step adjustment values can be realized. For example, in the lighting device 1 having a width of 300 mm (see the bottom part of FIG. 14), the adjustment width WJ of “140 mm” is realized by providing the side cover unit 50C instead of the side cover unit 50B. That is, at least 13 adjustment values of “20 mm to 140 mm” can be realized. Further, by changing the number of arrangements of the width adjustment joint units 60B and 60D, it is also possible to realize an adjustment width WJ in more stages.

  In the lighting device 1 having a width of 690 mm to 740 mm, a light emitting unit joint unit 70 </ b> A having a width of 10 mm is used as each light emitting unit joint unit 70.

  In the lighting device 1 having a width of 750 mm to 800 mm, a light emitting unit joint unit 70D having a width of 25 mm is used as each light emitting unit joint unit 70.

  Here, the total value WA8 of the width of the eight LED units 10 (400 mm = 50 mm × 8) and the width of the three power supply units 30 (210 mm = 70 mm × 3) is 610 mm.

  The illumination device 1 having a width of 690 mm (see the uppermost row in FIG. 20) is configured by providing the size adjustment unit 40 of “+80 mm”. For example, in addition to the arrangement of four light emitting unit joint units 70A (total width 40 mm = width 10 mm × 4), a side cover unit 50C (width 20 mm) is arranged on the left side of the LED unit 10 on the left end side. By arranging the side cover unit 50C (width 20 mm) on the right side of the LED unit 10 on the right end side, the size adjustment of “+80 mm” is realized. As described above, for the total value WA8 (610 mm) of the widths of the eight LED units 10 and the three power supply units 30, the size adjustment unit 40 (here, two side cover units 50C and four light emitting units) are used. The adjustment of “+80 mm” is performed by the joint unit 70A), and the lighting device 1 having the width TW of 690 mm is configured.

  Similarly, each lighting device 1 having a width TW of 700 mm, 710 mm, 720 mm, 730 mm, and 740 mm is provided with a size adjustment unit 40 of “+90 mm”, “+100 mm”, “+110 mm”, “+120 mm”, and “+130 mm”. It is constituted by using each. When four light emitting unit joint units 70A (total width 40 mm) are used, the value obtained by subtracting the adjustment amount by the light emitting unit joint unit 70A from the adjustment amount by the entire size adjustment unit 40 is the side cover unit 50. And the width adjustment joint unit 60 may be used. For example, in the lighting device 1 having the width TW of 740 mm, the side of “+90 mm” obtained by subtracting “40 mm” (the amount of adjustment by the light emitting unit joint unit 70A) from “+130 mm” (the amount of adjustment by the entire size adjustment unit 40) is the side. What is necessary is just to adjust by the cover unit 50 and the width adjustment joint unit 60.

  Furthermore, similarly, each lighting device 1 having each width TW of 750 mm, 760 mm, 770 mm, 780 mm, 790 mm, and 800 mm is “+140 mm”, “+150 mm”, “+160 mm”, “+170 mm”, “+180 mm”, “+190 mm”. The size adjustment units 40 of FIG. In the case where four light emitting unit joint units 70D (total width 100 mm) are used, “+40 mm”, “+50 mm”, “+60 mm”, and “+70 mm” are used by using the side cover unit 50 and the width adjustment joint unit 60. , "+80 mm", and "+90 mm" are further adjusted, so that the size adjustment unit 40 has the sizes of "+140 mm", "+150 mm", "+160 mm", "+170 mm", "+180 mm", and "+190 mm". It is only necessary that each adjustment be made.

  Each of the lighting devices 1 as described above is constructed as follows.

  Specifically, first, according to the designated width WD of the lighting device, the length (width) of the LED unit 10 in the X direction and the number of the LED units 10 arranged in the X direction (width direction), and the length of the power supply unit 30 in the X direction (Width) and the number of arrangements in the X direction (width direction). Then, both the total width of the LED unit 10 and the total width of the power supply unit 30 are calculated, and should be adjusted by the size adjustment unit 40 based on the total value WA of the two and the designated width (WD) of the lighting device. The adjustment width WJ (= WD-WA), which is the width, is determined.

  Next, from among a plurality of types of size adjustment units 40 (50A to 50C, 60B, 60D, 70A to 70D) having different widths, at least one size adjustment unit 40 for realizing the adjustment width WJ ( For example, only the side cover unit 50A) is determined.

  Then, a plurality of units including the determined at least one size adjustment unit 40, at least one LED unit 10, and at least one power supply unit 30 are arranged in combination in the width direction.

  By such a method, each lighting device 1 corresponding to the designated width WD is manufactured.

<2-8.1. Illumination device including one LED unit and one power supply unit>
Also, by combining a single LED unit 10 and one power supply unit 30, the lighting device 1 having a relatively small width TW can be configured (see FIG. 10). Specifically, the lighting device 1 (1Z) having a width of 140 mm is configured.

  A side cover unit 50A is provided on the left side of the LED unit 10, and a side cover unit 50E (see FIG. 7D) is provided on the right side of the power supply unit 30. The side cover unit 50E has a different shape from the side cover unit 50A, but has the same width (effective width) W51 (10 mm) as the side cover unit 50A.

<2-9. Effects of Embodiment>
In the above embodiment, as described with reference to FIGS. 11 to 14, twelve types of lighting devices 1 </ b> A to 1 </ b> L having different widths are used for two types of common components (10, 30) and a size adjusting device. Of the five types (50A, 50B, 50C, 60B, 60D). More specifically, 12 different adjustment widths WJ (each adjustment width in increments of 10 mm in a range of 20 mm to 130 mm) different from each other are realized by different combinations of a total of 5 types of components (50A, 50B, 50C, 60B, 60D). Is done. If the lighting device is specially ordered, usually, components corresponding to the respective adjustment widths WJ are individually designed. For example, in order to realize 12 types of lighting devices having different widths, 12 types of dedicated components are used. Provided separately. On the other hand, in the above-described embodiment, since it is realized by a combination of a relatively small number (five types) of components, the number of component types can be reduced.

  Further, in the above-described embodiment, as described with reference to FIGS. 15 to 20, further various widths can be provided according to the change in the number of the LED units 10 and the number of the power supply units 30. The lighting device 1 having the above configuration can be configured. For example, by combining a relatively large number (for example, 8) of LED units 10 and a relatively large number of power supply units 30 (for example, 3), a relatively large width (for example, 690 mm, 700 mm, 710 mm,. Illumination device 1 having a height of 800 mm) is configured (see FIG. 20).

  In particular, since each of the LED unit 10 and the power supply unit 30 has a width that is a multiple of the predetermined unit length ΔW, the total width of the arbitrary number of LED units 10 and the arbitrary number of power supply units 30 is also the predetermined unit length. It is a multiple of ΔW. Further, as described above, the total width of the size adjustment unit 40 is also an integral multiple of the predetermined unit length ΔW. As a result, the total width TW of the various units in the lighting device 1 is also an integral multiple of the predetermined unit length ΔW. That is, the illuminating device 1 having the widths TW different from each other by the predetermined unit width ΔW can be favorably realized.

  As described above, the lighting device 1 includes one of the plurality of combinations of the LED unit 10 and the power supply unit 30 and the plurality of size adjustment units 40 (the side cover unit 50, the width adjustment joint unit 60, and the light emitting unit joint unit 70). It is composed of a combination of the units to be used. Thereby, it can be configured as any one of the plurality of lighting devices 1 having a plurality of different widths TW in units of a predetermined unit length ΔW (10 mm) over a very wide range (here, 190 mm to 800 mm).

  In each lighting device 1, the size adjustment unit 40 that realizes each adjustment width WJ is selected from a plurality of types of size adjustment units 40 (50A to 50C, 60B, 60D, 70A to 70D, and the like). . Here, each adjustment width WJ is a value obtained by subtracting the total width of the width of the LED unit 10 and the width of the power supply unit 30 arranged in each lighting device 1 from the designated width WD.

  For example, as shown in FIG. 17, the adjustment width WJ in the lighting device 1 having each width of 440 mm to 490 mm is the width of the five LED units 10 arranged in the lighting device 1 (here, 250 mm = 50 mm × 4). ) And the total width WA5 (390 mm) of the two power supply units 30 (140 mm = 70 mm × 2) is subtracted from the designated width WD (440 mm to 490 mm) (50 mm to 100 mm).

  Then, the plurality of size adjustment units 40 are combined with the plurality of types of size adjustment units 40 (50A to 50C, 60B, 60D) such that each adjustment width WJ (50 mm to 100 mm) is equal to the total width of the plurality of size adjustment units 40. , 70A to 70D). For example, in the lighting device 1 having a width of 490 mm, an adjustment width of “100 mm” is realized by using two light emitting unit joint units 70A, two side cover units 50B, and two width adjustment joint units 60D.

  At this time, the adjustment width WJ is a combination of a P type (here, P = 3) side cover unit 50 and a Q type (here, Q = 2) width adjustment joint unit 60 and a predetermined number (here, two). The two side cover units 50B and the two side cover units 50B are set to be equal to one of the width values of the R stage (here, R = 6 and R> P + Q) realized by the light emitting unit joint unit 70 of FIG. And the width adjustment joint unit 60D are selected. Therefore, compared to the case where the adjustment units of six stages are individually prepared, the width of six stages (relatively many stages) can be realized with a relatively small number of component types (P + Q = 5). It is.

  In addition, in FIG. 17, with respect to the illumination device 1 having five LED units 10 and two power supply units 30, each adjustment width WJ in six steps in a range of 50 mm to 100 mm in 10 mm increments with respect to the basic width WA5 “390 mm”. Illustrated are a plurality of lighting devices 1 having a six-step width, but are not limited thereto. For example, with respect to the total width (410 mm) of the basic width WA5 (390 mm) and the two light emitting unit joint units 70A, a combination of three types of side cover units 50 and two types of width adjustment joint units 60 is used. Any one of the realized 13-step widths of “20 mm to 140 mm” may be added to build any one of the plurality of lighting devices 1 having the 13-step widths.

  Further, in the above embodiment, the plurality of lighting devices (excluding the lighting device 1Z) have a symmetrical unit configuration, and the same type and the same number of side cover units 50 are used on both left and right sides. Therefore, the number of types of parts can be further reduced (halved) as compared with the case where different types of side cover units 50 are used for the left side and the right side, respectively. The same effect can be obtained by using the same type and the same number of width adjustment joint units 60 on both the left and right sides. The same applies to the light emitting unit joint unit 70.

  Further, in the above embodiment, the LED unit 10 and the power supply unit 30 are provided separately. Therefore, the influence of the heat of the power supply unit 37 on the LED light source can be reduced. In addition, by separating the two units 10 and 30, maintenance of the lighting device 1 can be facilitated.

  In the above embodiment, the LED unit 10 and the power supply unit 30 are provided separately, and the LED unit 10 and the power supply unit 30 are combined and provided in the lighting device 1. Therefore, compared to the case where the integrated components of the LED unit 10 and the power supply unit 30 are individually designed and constructed according to the width of the lighting device 1, the lighting devices 1 having different widths are flexibly and easily constructed. It is possible.

<3. Modifications>
The embodiments of the present invention have been described above, but the present invention is not limited to the above-described contents.

  For example, in the above embodiment, the maximum width of the lighting device 1 is 800 mm, but a lighting device having a larger width may be realized.

  Further, in the above embodiment, when a plurality of lighting devices 1 having different widths in increments of the value ΔW are constructed, the aspect in which the value ΔW is 10 mm is exemplified, but the embodiment is not limited to this. For example, the value ΔW may be any other value.

  In the above embodiment, the units are mainly joined to each other on the upper surface. For example, bonding with the power supply unit 30 is performed on the upper surface of the LED unit 10. More specifically, the power supply unit 30 and the LED unit 10 are joined to each other at a joint surface (concave portion) 11 a on the upper surface of the base member 11 and a projecting portion (convex portion) 31 a of the upper base member 31. However, the present invention is not limited to this, and the joining of the units may be performed using only the side surfaces of the units. For example, the connection with the power supply unit 30 may be performed using the side surface of the LED unit 10 (not using the upper surface of the LED unit 10).

  Further, in the above embodiment, the case where P = 3 and Q = 2 is exemplified, but the present invention is not limited to this. For example, as the plurality of types of size adjustment units 40, there are P types (where the value P is a natural number) of side cover units 50 having a width (a natural number) that is a multiple of a half of the predetermined unit width ΔW, Q-type (where the value Q is a natural number) width adjustment joint unit 60 having a width of a multiple of a half value (a natural number) may be prepared. The value P and the value Q may each be 1. In the case of Q = 1, a plurality of different widths may be realized by connecting and using a plurality of width adjustment joint units 60 of the same type (predetermined width (for example, 5 mm width)). However, at least one of the value P and the value Q is preferably 2 or more.

  Further, in the above embodiment, the lighting device using the LED (light emitting diode) as the light source is exemplified, but the present invention is not limited to this. For example, it is also possible to apply the above-described concept to a lighting device using another light source (such as a fluorescent lamp or an organic EL).
