Description

[Technical field]

[0001] The present disclosure relates to a lighting device. [Background technology]

[0002] Conventionally, in order to improve transportation stability, it has been considered to make the transportation state compact by making the structure disassembleable or deformable.

[0003] For example, Patent Document 1 discloses a lighting fixture including a fixture body, a reflector, and a supporting lamp socket. With this lighting fixture, packaging costs and transportation costs can be reduced. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 08-185708 Summary of the Invention [Problem to be solved by the invention]

[0005] However, if the lighting fixture in Patent Document 1 is disassembled during transportation, it must be reassembled when installing, which increases the amount of work. In some cases, tools are required for disassembly. Furthermore, the power source of the lighting device is generally thick, which causes the volume to increase when stacked during transportation. Also, the lighting device may become unstable during transportation.

[0006] In view of the above problems, the present disclosure aims to provide a lighting device that can be transported compactly and stably regardless of the thickness of the power source during transportation, and that does not require any additional assembly when installing the lighting device. [Means for solving the problem]

[0007] A lighting device according to the present disclosure is a lighting device including a rectangular housing, a light-emitting unit, and a power supply unit that supplies power to the light-emitting unit, the housing including a first surface, a second surface, a third surface, and a fourth surface each having a predetermined height from a bottom of the housing, the first surface being a surface on which the power supply unit is installed, and the second surface being a surface on which the power supply unit is not installed, the height of the power supply unit being A, the height from the bottom of the housing to the third surface or the fourth surface being B, the height from the bottom of the housing to the second surface being C, and the height from the bottom of the housing to the first surface being D, where A>(BD)+(BC) is satisfied, and when one lighting device is overlaid upside down on the other lighting device, the second surfaces of the one lighting device and the other lighting device include a cutout portion such that the other lighting device and the power supply unit of the one lighting device are engageable with each other. Effect of the Invention

[0008] As described above, according to the present disclosure, it is possible to provide a lighting device that can be transported compactly and stably regardless of the thickness of the power source during transportation, and that does not require any additional assembly when installing the lighting device.

[0010] Hereinafter, a preferred embodiment of the present disclosure will be described in detail with reference to the drawings. Note that the present embodiment described below does not unduly limit the contents of the present disclosure described in the claims, and all of the configurations described in the present embodiment are not necessarily essential as the solution means of the present disclosure. Note that in the drawings, the X axis is the width direction of the lighting device, the Y axis is the depth direction, and the Z axis is the height direction.

[0011] 1 is a diagram showing two lighting devices 100a, 100b stacked one on top of the other. The lighting device 100 according to the present disclosure is shipped with the two lighting devices 100a, 100b stacked one on top of the other.

[0012] The lighting device 100 according to the present disclosure is mainly installed in a building such as a building. The lighting device 100 according to the present disclosure is installed near an air conditioner in a building, etc. The lighting device 100 according to the present disclosure is a grid lighting device, etc.

[0013] Conventional devices may also be stacked on top of each other for transportation, but in such cases the thickness of the power supply causes an increase in volume. In addition, the device may become unstable during transportation. Furthermore, when stacking devices on top of each other, cushioning material is provided to prevent interference between the devices, but this increases the size of the packaging during transportation. Also, if the device is designed to be deformable when assembled, the strength of the device may decrease, which may cause defects. Furthermore, the area of ​​the air conditioning return is determined for each building, and whether it is large or small, it may have an adverse effect on the air conditioning equipment.

[0014] Therefore, according to the lighting device 100 of the present disclosure, the two lighting devices 100a, 100b can be stacked vertically to be transported compactly and stably, regardless of the thickness of the power source. In addition, less cushioning material is required, which reduces costs. In addition, no additional work is required when installing the lighting device, improving installation workability. In addition, the lighting device has sufficient strength. In addition, since the area of ​​the air conditioning return is not changed, the air conditioning equipment is not affected, and the stability of the packaged state is improved. The configuration of the lighting device 100 of the present disclosure will be described below.

[0015] As shown in FIG. 1, the lighting device according to the present disclosure includes housings 10a and 10b, light-emitting units 20a and 20b, and power supply units 30a and 30b.

[0016] The housings 10a and 10b are mainly rectangular. The housings 10a and 10b are made of a material that is difficult to deform. An example of a material that is difficult to deform is metal. The detailed structure of the housings 10a and 10b will be described later.

[0017] The light-emitting unit 20a is provided below the first surface 11a and the second surface 12a of the upper lighting device 100a. The light-emitting unit 20b is provided above the first surface 11b and the second surface 12b of the upper lighting device 100b. The light-emitting units 20a and 20b use LEDs or the like as light emitters.

[0018] The power supply units 30a and 30b supply power to the light emitting units 20a and 20b.

[0019] Fig. 2 is a diagram of the upper lighting device 100a of the two lighting devices 100a and 100b shown in Fig. 1. Fig. 3 is a diagram of the lower lighting device 100b of the two lighting devices 100a and 100b shown in Fig. 1. In Fig. 2, the upper lighting device 100a shown in Fig. 1 is rotated by 180° for convenience.

[0020] 2 and 3, the housings 10a and 10b include first surfaces 11a and 11b, second surfaces 12a and 12b, third surfaces 13a and 13b, and fourth surfaces 14a and 14b that are at a predetermined height from the bottoms 10c of the housings 10a and 10b. The first surfaces 11a and 11b, the second surfaces 12a and 12b, the third surfaces 13a and 13b, and the fourth surfaces 14a and 14b are approximately parallel to the plane defined by XY.

[0021] The first surfaces 11a and 11b are surfaces on which the power supply units 30a and 30b are disposed. In addition to the power supply units 30a and 30b, electronic components 31a and 31b are attached to the first surfaces 11a and 11b.

[0022] Examples of the electronic components 31a and 31b include terminals, terminal blocks, harnesses, etc. The first surfaces 11a and 11b, second surfaces 12a and 12b (described later), third surfaces 13a and 13b, and fourth surfaces 14a and 14b are flat surfaces.

[0023] The second surfaces 12a and 12b are surfaces on which the power supply units 30a and 30b are not provided. The second surfaces 12a and 12b are provided with cutout portions 40a and 40b. The cutout portions 40a and 40b will be described later.

[0024] When one (upper) lighting device 100a is inverted and stacked with the other (lower) lighting device 100b, the third surfaces 13a, 13b and the fourth surfaces 14a, 14b provided on one (upper) lighting device 100a come into contact with the third surfaces 13a, 13b and the fourth surfaces 14a, 14b provided on the other (lower) lighting device 100b. That is, when the two lighting devices 100a, 100b are inverted and stacked, the third surface 13a of one (upper) lighting device 100a comes into contact with the fourth surface 14b of the other (lower) lighting device 100b. Also, the fourth surface 14a of one (upper) lighting device 100a comes into contact with the third surface 13b of the other (lower) lighting device 100b. In this way, less cushioning material is required, which reduces costs.

[0025] The third surface 13a, 13b includes third side walls 23a, 23b extending vertically from the third surface 13a, 13b toward the bottom 10c of the housing 10a, 10b. The fourth surface 14a, 14b includes fourth side walls 24a, 24b extending vertically from the fourth surface 14a, 14b toward the bottom 10c of the housing 10a, 10b. The third side walls 23a, 23b and the fourth side walls 24a, 24b are approximately balanced in the Z direction. The heights of the third side walls 23a, 23b and the fourth side walls 24a, 24b may be the same or different.

[0026] The cutouts 40a, 40b are provided on the second surfaces 12a, 12b as shown in FIG. 3. The cutouts 40a, 40b are cutout-shaped holes. When the other (lower) lighting device 100b is inverted upside down and stacked on the one (upper) lighting device 100a, the cutouts 40a, 40b are provided on the second surfaces 12a, 12b of the one (upper) lighting device 100a and the other (lower) lighting device 100b so that the power supply units 30a, 30b of the other (lower) lighting device 100b and the one (upper) lighting device 100a can be engaged with the second surfaces 12a, 12b of the one (upper) lighting device 100a and the other (lower) lighting device 100b. The power supply unit 30a of the one (upper) lighting device 100a shown in FIG. 2 engages with the cutout 40b of the other (lower) lighting device 100b shown in FIG. 3. When they are stacked together, they become the two lighting devices 100a and 100b shown in FIG.

[0027] In this way, the tall power supply unit 30a of one (upper) lighting device 100a engages with the cutout portion 40b of the other (lower) lighting device 100b and fits within the housing 10b of the other (lower) lighting device 100b, making it possible to transport the lighting device in a compact manner regardless of the thickness of the power supply.

[0028] The area of ​​the surface formed by the XY plane of the power supply units 30a and 30b is smaller than the area of ​​the surface formed by the XY plane of the cutouts 40a and 40b so that the cutouts 40a and 40b can be engaged with the power supply units 30a and 30b. The height of the power supply units 30a and 30b themselves is smaller than the depth of the cutouts 40a and 40b. Furthermore, when the two lighting devices 100a and 100b are stacked upside down and the cutouts 40a and 40b are engaged with the power supply units 30a and 30b, there may be a small gap between the cutouts 40a and 40b and the power supply units 30a and 30b.

[0029] Fig. 4 is a front view of the lighting device 100b shown in Fig. 3. In addition, Fig. 5 is a view of the lighting device 100b shown in Fig. 4 as seen from A, Fig. 6 is a view of the lighting device 100b shown in Fig. 4 as seen from B, Fig. 7 is a view of the lighting device 100b shown in Fig. 4 as seen from C, and Fig. 8 is a view of the lighting device 100b shown in Fig. 4 as seen from D.

[0030] 4 to 8, the lighting devices 100a and 100b according to the present disclosure satisfy A>(BD)+(BC) where A is the height of the power supply units 30a and 30b (height from the first surface to the power supply unit), B is the height from the bottom 10c of the housings 10a and 10b to the third surface 13a, 13b or the fourth surface 14a, 14b, C is the height from the bottom 10c of the housings 10a and 10b to the second surface 12a, 12b, and D is the height from the bottom 10c of the housings 10a and 10b to the first surface 11a, 11b. In this way, the lighting devices can be transported compactly and stably, regardless of the thickness of the power supply during transportation.

[0031] 4 to 8, if the height of electronic components 31a and 31b is E (height from first surfaces 11a and 11b to electronic components 31a and 31b), it is preferable to satisfy E<2B-DC. In this way, the power source can be transported compactly and stably, regardless of the thickness of the power source.

[0032] 9 is a view of the lighting devices 100a and 100b shown in FIG. 1 as viewed from D. As shown in FIG. 9, the lighting devices 100a and 100b according to the present disclosure include mounting members 50a and 50b extending in the height direction for mounting to a ceiling. The mounting members 50a and 50b are attached to the third side wall and the fourth side wall. The mounting members 55a and 55b extend from the third side walls 23a and 23b near the third surfaces 13a and 13b and the fourth side walls 24a and 24b near the fourth surfaces 14a and 14b toward the bottom 10c of the housings 10a and 10b.

[0033] The mounting members 50a and 50b are provided at the center of the housings 10a and 10b in the depth direction (Y direction).

[0034] In addition, when one (upper) lighting device 100a and the other (lower) lighting device 100b are inverted and stacked on top of each other, the central axis 50am of the mounting member 50a provided on one (upper) lighting device 100a is configured to be located inside the width 50bL of the mounting member 50b provided on the other (lower) lighting device 100b.

[0035] Fig. 10 is an enlarged view of X shown in Fig. 9. Fig. 11 is a view showing a mounting member 50. As shown in Fig. 10 and Fig. 11, the ends of the mounting members 50, 50a, 50b have protrusions 52, 52a, 52b and recesses 53, 53a, 53b. The protrusion 52a of the mounting member 50a of one (upper) lighting device 100a fits into the recess 53b of the mounting member 50b of the other (lower) lighting device 100b.

[0036] In this way, when the two lighting devices 100a, 100b are stacked, they can be transported more stably. The convex parts 52, 52a, 52b are convex parts, and the concave parts 53, 53a, 53b are concave parts from the convex parts 52, 52a, 52b. The parts of the mounting members 50, 50a, 50b located on the third surfaces 13a, 13b and the fourth surfaces 14a, 14b are lower by the height of the convex parts 52, 52a, 52b of the mounting members 50, 50a, 50b, so that the third surfaces 13a, 13b and the fourth surfaces 14a, 14b can come into contact with each other.

[0037] Fig. 12 is a diagram showing modified examples of mounting members 50, 50a, and 50b. Fig. 13 is a front view of mounting members 50a and 50b shown in Fig. 12. Note that some components of lighting devices 100a and 100b shown in Fig. 12 are omitted.

[0038] The lighting devices 100a, 100b shown in Fig. 12 and Fig. 13 are provided with mounting members 50a, 50b extending in the height direction on the third side walls 23a, 23b and the fourth side walls 24a, 24b for mounting to a ceiling. The mounting members 50a, 50b shown in Fig. 12 and Fig. 13 extend in the height direction from the third side walls 23a, 23b and the fourth side walls 24a, 24b near the bottom 1c of the housings 10a, 10b on the side opposite to the third surfaces 13a, 13b.

[0039] The mounting members 50a, 50b are provided with key-shaped members 51a, 51b at their tips so that the mounting member 50a provided on the one (upper) lighting device 100a and the mounting member 50b provided on the other (lower) lighting device 100b can be engaged with each other when the other (lower) lighting device 100b is inverted upside down and stacked on top of the other (upper) lighting device 100a.

[0040] As shown in Figures 12 and 13, the key-shaped members 51a, 51b are key-shaped and made up of J-shaped portions. In detail, the key-shaped members 51a, 51b shown in Figures 12 and 13 are made up of bases 54a, 54b, key-shaped members 51a, 51b located at their tips, and connecting members 55a, 55b that extend in the Z direction from the bases 54a, 54b and connect to the key-shaped members 51a, 51b.

[0041] The lighting devices 100a, 100b according to the present disclosure include the key-shaped members 51a, 51b shown in Figs. 12 and 13, which allow the two lighting devices 100a, 100b to be fixed together, making them more stable when transported.

[0042] 14 and 15 are cross-sectional views taken along the line XIV-XIV in FIG. 4. The lighting device 100 according to the present disclosure is provided with a light-emitting unit 20 in the form of a box provided in a housing. In the device shown in FIG. 14, the end 21 of the light-emitting unit 20 is arranged so as to be positioned within the air-conditioning intake 15. That is, this indicates that one of the ends 21 of the light-emitting unit 20 is in the air-conditioning intake area 15S in the cross-sectional view. In the device shown in FIG. 14, since the end 21 of the light-emitting unit 20 is positioned within the air-conditioning intake 15, the amount of air intake increases, causing adverse effects.

[0043] 15, it is preferable that the end 21 of the light emitting unit 20 is arranged so as not to be positioned within the air conditioning intake 15. In other words, this means that one and the other ends 21 of the light emitting unit 20 are not in the air conditioning intake area 15S in a cross-sectional view. In this way, the amount of air intake can be adjusted, and the above-mentioned adverse effects can be prevented.

[0044] As described above, the lighting devices 100, 100a, and 100b according to the present disclosure can be transported compactly and stably, regardless of the thickness of the power source during transportation.

[0045] Although each embodiment and each example of the present disclosure have been described in detail above, it will be readily apparent to those skilled in the art that many modifications are possible without substantially departing from the novel features and effects of the present disclosure. Therefore, all such modifications are intended to be included within the scope of the present disclosure.

[0046] For example, a term described at least once in the specification or drawings together with a different term having a broader or similar meaning may be replaced with that different term anywhere in the specification or drawings. In addition, the configuration and operation of the high frequency multilayer board are not limited to those described in the embodiments and examples of the present disclosure, and various modifications are possible.
