In light source unit 2, as shown in figure 16, power supply unit 6 and the 1st fixture 8A in power supply unit 6 and the 1st to pacify Fill between apparatus 8A there is no the mode of live part mounting plate 40 one side (the 2nd face 402) along prescribed direction (mounting plate 40 the 2nd direction) arrangement.Live part is the part being powered in luminaire 1, e.g. electric wire 200.In particular, in this reality It applies in mode, power supply unit 6 is configured at compared to the 2nd fixture 8B close to the position of the 1st fixture 8A.In more detail It says, power supply unit 6 and the 1st fixture 8A are configured in the prescribed direction (front and back in the 2nd direction of mounting plate 40, Figure 16 To) on it is adjacent.Therefore, between power supply unit 6 and the 1st fixture 8A, do not guarantee the region for configuring live part (charged area, wiring area).
In addition, in power supply unit 6, the long side direction of shell 60 is orthogonal with prescribed direction (front-rear direction).Shell 60 Long side direction need not be orthogonal with prescribed direction with stringent meaning, can also intersect.In addition, shell 60 is located at mounting plate 40 The center of left and right directions in 2nd face 402.Also, the 1st fixture 8A is located at the right and left in the 2nd face 402 of mounting plate 40 To center.The 1st fixture 8A is located at the central portion of the long side direction of the shell 60 of power supply unit 6 as a result,.Therefore, the 1st peace It is not opposed with input connector 62 and out connector 63 in prescribed direction (front-rear direction) to fill apparatus 8A, with shell 60 is opposed.
Also, the 1st fixture 8A, shell 60 and mounting plate 40 are designed to the phase of shell 60 as shown in Figure 16 For the height in 2nd faces 402 relative to mounting plate 40 of the height H1 than the 1st fixture 8A in the 2nd face 402 of mounting plate 40 H2 high.Shell 60 excessively enters utensil as hand for inhibiting operator etc. from the gap of installation component 4 and appliance body 10 as a result, Wall in main body 10 functions.
In addition, as shown in figure 16, the 1st end 201 of electric wire 200 is electrically connected with connector 62, and the 2nd end 202 is relative to power supply Unit 6 is located at the side opposite with fixture 8A.Here, electric wire 200 passes through the emulsion sheet 432 and peace of the 1st holding appliance 43 Between loading board 40 and between the emulsion sheet 442 and mounting plate 40 of the 2nd holding appliance 44, and it is fixed in mounting plate 40.As a result, 2nd end 202 of electric wire 200 is held in installation in a manner of being located at the side opposite with fixture 8A relative to power supply unit 6 Plate 40.
In above-described luminaire 1, as shown in figure 14, multiple bolt insertion holes 1101 (1101A, 1101B, 1101C, 1101D) it is arranged along the 1st straight line L10 in the plane (datum plane) orthogonal with the thickness direction of bottom wall 110.1st is straight Line L10 is orthogonal with the 2nd straight line L20 that a pair of of engaging portion 114,114 is connected to each other in datum plane.Here, a pair of combine Portion 114,114 is combined with a pair of of fixture 8,8 of light source unit 2.Therefore, a pair of of engaging portion 114,114 is connected to each other 2nd straight line L20 is consistent with the straight line that a pair of of fixture 8A, 8B are connected to each other.Thus it may also be said that the 1st straight line L10 is in base The line orthogonal being connected to each other in directrix plane and by a pair of of fixture 8A, 8B.In addition, the 1st straight line L10 is worn in datum plane Cross the center between a pair of of hook portion (engaging portion) 114,114.
In addition, in luminaire 1, as shown in figure 14, power supply unit 6 and functional unit (terminal board 13) are in datum plane The interior position for being located at opposite side each other relative to the 1st straight line L10.Therefore, it is possible to reduce power supply unit 6 and functional unit (terminal Platform 13) possibility with the interference of hanger bolt 90.Moreover, power supply unit 6 is electrically connected with terminal board 13 using electric wire 200. Electric wire 200 is held in mounting plate 40 by the 1st holding appliance 43.Here, the 1st holding appliance 43 is located at the in datum plane On 1 straight line L10.That is, on the 1st straight line L10, electric wire 200 is fixed on mounting plate 40, therefore can reduce from multiple spiral shells The possibility that some hanger bolt 90 being inserted into appliance body 10 in bolt inserting hole 1101 is contacted with electric wire 200. Also, the 1st holding appliance 43 has the emulsion sheet 432 between mounting plate 40 and bottom wall 110, in emulsion sheet 432 and installation Electric wire 200 is kept between plate 40.Therefore, electric wire 200 can be protected against the influence of hanger bolt 90 by emulsion sheet 432. In addition, the 1st holding appliance 43 is not be overlapped with any of multiple bolt insertion holes 1101 in datum plane.As a result, can Enough make electric wire 200 far from hanger bolt 90.Therefore, it is possible to further decrease the possibility that hanger bolt 90 is contacted with electric wire 200.
Also, as shown in Figure 10 and Figure 11,2 LED modules 3 (light source) be installed in mounting plate 40 with one side (the 2nd face 402) face (the 1st face 401) of opposite side.Therefore, with mounting plate 40 one side (the 2nd face 402) install light source unit 2 the case where It compares, the light source unit 2 of bigger can be used.
Then, illustrate to construct luminaire 1 in the operation of ceiling.The operator of construction operation is carried out first to bottom wall 110 inserting hole 1100 inserts power cord, (is later bolt insertion hole in Figure 5 to insert to bolt insertion hole 1101 Hanger bolt 90 1101B) tightens nut 91, and appliance body 10 is thus installed to hanger bolt 90 (with reference to Fig. 5).In addition, Appliance body 10 is disposed in top by operator by the way that the power cord introduced from inserting hole 1100 and terminal board 13 are carried out wiring Canopy.In addition, appliance body 10 makes receiving portion 11 be conducted by conducting portion 113 with reflecting member 12, therefore can save pair The trouble of receiving portion 11 and this two side progress grounding construction of reflecting member 12.
Then, operator is disposed through side wall 111D of the through hole 124 of the side plate 121D of rear side on rear side of being set to Hook portion 114B hole 1143 be inserted into rear side fixture (the 2nd fixture) 8B installation spring 80 the 1st arm 82. At this point, operator is inserted into the long side direction of the hook plate 820 of the 1st arm 82 on the 2nd tab 1142 of hook portion 114B End, it is whole from insertion hook plate 820 between piece 1140 and the 1st tab 1141 is temporarily held later.In addition, if operator is It is inserted into the hole of hook portion 114B and power upward is applied to the 1st arm 82 for installing spring 80, then the extension of the 1st arm 82 Hook tabs 820 becomes the state substantially parallel with the axis of coil part 81, therefore is easy to seek to improve workability.Then, operator will What the hook plate 820 of the 1st arm 82 hung over hook portion 114B temporarily holds piece 1140, thus enables that light source unit 2 is protected temporarily It is held in appliance body 10.Here, the 1st arm 82 at the position that abuts of limiting unit 853 of installation part 85 by limiting displacement, Therefore it is possible to realize inhibit to be plastically deformed caused by excessive displacement.
Operator carries out terminal board 13 and power supply unit in the state of so that light source unit 2 is temporarily held in appliance body 10 6 wiring operation.In particular, the 2nd end 202 of electric wire 200 relative to power supply unit 6 be located at it is opposite with the 1st fixture 8A Side, therefore relatively close to the 2nd fixture 8B.Therefore, it is easy to carry out wiring operation.In addition, temporarily holding state above-mentioned Under, it temporarily holds between piece 1140 and the 1st tab 1141 even if hook plate 820 is moved to, dashes forward since hook plate 820 hangs over the 2nd Piece 1142, therefore it is also extremely low to install the careless possibility for being detached from hook portion 114 of spring 80.
Then, the 1st arm 82 of the installation spring 80 of the fixture 8A of front side is inserted by operator is set to front side Side plate 121C hook portion 114A hole 1143.At this point, operator needs to press the installation spring 80 of the 1st fixture 8A Make its flexure.However, live part (such as electric wire 200) is not present between power supply unit 6 and the 1st fixture 8A.Therefore, Operator accidentally contacts that the possibility of live part is low.Therefore, it is possible to improve the operation that light source unit 2 is installed to appliance body 10 Safety.
Here, at the both ends of long side direction of the shell 60 of power supply unit 6, there are input connector 62 and out connectors 63, and the long side direction of shell 60 and the prescribed direction of power supply unit 6 and the 1st fixture 8A arrangements are intersected.Operator contacts The possibility of live part as input connector 62, out connector 63 is low.Therefore, it is possible to further increase light source Unit is installed to the safety of the operation of appliance body.
In particular, the 1st fixture 8A is not opposed with input connector 62 and out connector 63 in the longitudinal direction, But it is opposed with shell 60.Therefore, even if in the case where operator contacts power supply unit 6, nor contacting that input such as connects Live part as device 62, out connector 63, but contact shell 60.Therefore, it is possible to further increase light source unit 2 It is installed to the safety of the operation of appliance body 10.
Also, as shown in figure 18, the height H1 in the 2nd face 402 relative to mounting plate 40 of shell 60 is than the 1st fixture The height H2 high in the 2nd face 402 relative to mounting plate 40 of 8A.Therefore, hand for inhibiting operator by shell 60 etc. is from peace Loading board 40 and the gap of appliance body 10 excessively enter in appliance body 10.
In addition, the 2nd end 202 of electric wire 200 is located at the side opposite with the 1st fixture 8A relative to power supply unit 6, because This operator contacts that the possibility at the 2nd end 202 of electric wire 200 is low.Light source unit 2 is installed to therefore, it is possible to further increase The safety of the operation of appliance body 10.
Later, light source unit 2 is lifted and is accommodated into receiving portion 11 by operator.When receiving portion is arrived in the receiving of light source unit 2 When in 11, the 1st arm 82 of the installation spring 80 of fixture 8A, 8B hangs over hook portion 114A, 114B of side wall 111C, 111D Edge.As a result, light source unit 2 is supported on appliance body 10 by 2 spring forces for installing spring 80.That is, light Source unit 2 by by the 1st fixture 8A and the 2nd fixture 8B respectively with hook portion (the 1st engaging portion) 114A and hook portion (the 2nd engaging portion) 114B is in conjunction with being installed on appliance body 10.If here, the combination operation of fixture 8 and hook portion 114 It is carried out being then difficult to later by visual observation.Therefore, by first carrying out the combination of the 2nd fixture 8B and hook portion 114B Operation can further increase the safety for the operation that light source unit 2 is installed to appliance body 10.
Here, in luminaire 1, as shown in figure 14, multiple bolt insertion holes 1101 (1101A, 1101B, 1101C, The 1st straight line L10 1101D) arranged is orthogonal with the 2nd straight line L20 that a pair of of hook portion (engaging portion) 114,114 is connected to each other. Thereby, it is possible to far from hanger bolt 90 outstanding in appliance body 10 position into be about to each fixture 8 with it is corresponding The operation that hook portion 114 is combined.Therefore, hanger bolt 90 is not easy to interfere operation.Thereby, it is possible to be easy to carry out light source Unit 2 is installed to the operation of appliance body 10.In addition, the 1st straight line L10 is between a pair of of hook portion (engaging portion) 114,114 Center.It, can be more easily into being about to light source therefore, it is possible to make each hook portion (engaging portion) 114 be sufficiently apart from hanger bolt 90 Unit 2 is installed to the operation of appliance body 10.
By process as described above, the construction operation of luminaire 1 is completed.
When 2 LED modules 3 are lighted by the direct current power by being supplied from power supply unit 6, radiated from each LED module 3 Light is irradiated to illumination space after being spread through the bottom 50 of cover 5 and peripheral wall portion 51 and in bottom 50 and peripheral wall portion 51.Here, Peripheral wall portion 51 have receiving portion 11 outwardly projecting 1st peripheral wall portion in lower section 511 (being also sometimes referred to as front wall portion below) and The 2nd peripheral wall portion 512 (being also sometimes referred to as right wall portion below) (0, Figure 11 and Figure 13 referring to Fig.1) being housed in receiving portion 11. Through the side plate of the light member for mount 4 of the part of the close upper end of the 2nd peripheral wall portion 512 of transmission in the light of the 2nd peripheral wall portion 512 41 block, therefore are not easy to drain in receiving portion 11.In addition, through the close upper end of the 2nd peripheral wall portion 512 part light by side plate It is irradiated to illumination space after 41 side (reflecting surface) reflection.Therefore, it is possible to inhibit side plate 41 and the peripheral wall portion in light source unit 2 Gap 20 (referring to Fig.1 3) between 51 is dimmed (brightness reduction).As a result, light source unit 2 can inhibit the peripheral portion of cover 5 Brightness reduction come seek improve light the uniformity.Also, luminaire 1 will be in the peripheral wall portion 51 in light source unit 2 The upper part of 2nd peripheral wall portion 512 is received into receiving portion 11, therefore, by the way that side plate 41 to be hidden in receiving portion 11, with The situation that 2 peripheral wall portions 512 integrally expose is compared, and beautiful reduction can be inhibited.Wherein, light source unit 2 can also be configured to The outside of side plate 41 configures peripheral wall portion 51.
In addition, cover 5 is configured to the thickness direction (upper and lower relative to installation base plate 31 compared to the 1st peripheral wall portion 511 To) tilt angle theta 1 for the 2nd peripheral wall portion 512 the tilt angle theta 2 relative to upper and lower directions it is small (referring to Fig.1 3).Right In the case that crimped processing is implemented on the surface of peripheral wall portion 51, need to add pattern draft to peripheral wall portion 51.However, being pulled out in order to additional Mould gradient and the angle of inclination on the surface of peripheral wall portion 51 is bigger, then the distance between the side wall 111 of peripheral wall portion 51 and receiving portion 11 It also becomes larger.Moreover, the distance between peripheral wall portion 51 and the side wall 111 of receiving portion 11 are bigger, then appliance body 10 and light source unit 2 Between gap it is more obvious, therefore there is a possibility that the beauty of luminaire 1 is impaired.
It is preferred, therefore, that peripheral wall portion 51 is divided into the close to the side (side far from installation component 4) of bottom 50 The of 1 peripheral wall portion 511 and the side (close to the side of installation component 4) for the 1st peripheral wall portion 511 far from bottom 50 2 peripheral wall portions 512.If the tilt angle theta 1 of the 1st peripheral wall portion 511 is set as the angle needed for pattern draft and the 2nd peripheral wall portion 512 tilt angle theta 2 be set as less than the 1st peripheral wall portion 511 tilt angle theta 1 angle, then do not make appliance body 10 with It is easy to implement crimped processing to the surface of peripheral wall portion 51 while gap between light source unit 2 is obvious.
Here, forming the line expansion of metal material of the linear expansivity of the synthetic resin material of cover 5 than forming installation component 4 Rate is quite high (such as 6 times~7 times degree), therefore there is a possibility that the cover 5 of expansion is abutted with side plate 41.If the cover of expansion 5 peripheral wall portion 51 is abutted with side plate 41, it is likely that generates abnormal sound from cover 5 or cover 5 is plastically deformed.Accordingly, it is preferred that It is that light source unit 2 is provided between side plate 41 along the thickness side with mounting plate 40 in peripheral wall portion 51 (the 2nd peripheral wall portion 512) To the gap 20 in orthogonal direction (left and right directions and front-rear direction).Preferably, gap 20 is at least configured to the cover 5 of expansion Peripheral wall portion 51 do not contacted with side plate 41 or will not be from side plate 41 by excessive power peripheral wall portion 51 contacts degree Size.
Here, when light source unit 2 is contained in receiving portion 11, it is installed on the power supply unit 6 in the 2nd face 402 of mounting plate 40 And wireless communication unit 7 is abutted with the bottom wall 110 of receiving portion 11, it is possible to single to power supply unit 6 and wireless communication from bottom wall 110 Member 7 applies stress.If applying stress to power supply unit 6 and wireless communication unit 7, it is likely that be happened at power supply unit 6 Shell 60, wireless communication unit 7 shell 70 on stay the undesirable conditions such as scar.However, being arranged in appliance body 10 restricted Piece 115, therefore light source unit 2 is abutted by the 2nd face 402 of mounting plate 40 with the lower end of margining tablet 115 in receiving portion 11 Light source unit 2 position by limitation (with reference to Figure 22).Therefore, power supply unit 6 and wireless communication unit 7 are not supported with mounting plate 40 It connects, it is possible to realize reduce the stress that light source unit 2 is applied to from appliance body 10.
In addition, margining tablet 115 is formed as prominent into receiving portion 11 from the side wall 111 of receiving portion 11.Therefore, with margining tablet 115 compare the case where projecting to except receiving portion 11, and it is possible to realize the miniaturizations of receiving portion 11.Also, multiple margining tablets 115 are each Idiomorphism becomes from non-conterminous 2 side walls 111 (side wall 111 in left side and the side wall 111 on right side) in 4 side walls 111 respectively It is prominent.Thus, in the state that light source unit 2 is installed on appliance body 10, the 2nd face of multiple margining tablets 115 and mounting plate 40 402 abut, and thus, it is possible to seek reduction and inclined inhibition of the light source unit 2 relative to the shaking of appliance body 10.In addition, Each side wall 111 is configured with margining tablet 115 in the position close to the corner of bottom wall 110, therefore can further seek light source unit 2 reductions relative to the shaking of appliance body 10 and inclined inhibition.In addition, not having hook portion in 4 side walls 111 114 2 side walls 111 (side wall 111 of the left and right sides) are provided with multiple margining tablets 115.Thus, multiple margining tablets 115 and peace Left and right ends in 2nd face 402 of loading board 40 abut, and thus, it is possible to inhibit the light source unit 2 with 2 fixtures 8 for fulcrum Swing (shaking).
Here, the installation spring 80 of light source unit 2 is in the state that light source unit 2 is installed on appliance body 10, across setting The hole of the hook portion 114 for the side wall 111 for being placed in receiving portion 11 and project to except receiving portion 11 (with reference to Fig. 2).That is, according to Funerary objects tool 1 multiple respective arms of fixed spring will not more up be protruded as previous example than the top surface of appliance body, therefore Need not the space for making the 1st arm 82 of installation spring 80 keep out of the way be set in the top of appliance body 10.As a result, illumination Utensil 1 is easy the workability for seeking to improve construction operation.
In addition, the 1st arm 82 is formed as installing structure with along from 4 direction outstanding (front-rear direction) of installation component is separate Part 4 and be bent to direction (downward) of the direction of insertion (upper and lower directions) along light source unit 2 far from bottom wall 110.Therefore, energy It enough avoids due to occurring from the 1st arm 82 of the installation spring 80 outstanding of side wall 111 with the component more against the top than appliance body 10 Interference and the workability of construction operation reduce the case where.
Also, light source unit 2 has multiple (such as 2) and installs spring 80.This 2 installation springs 80 are in installation component 4 Opposed 2 while (front side while and rear side side) respectively respectively be configured at least one.Thus, operator is from appliance body 10 when unloading light source unit 2, as long as extracting each installation bullet from the hole of hook portion 114 after pulling down light source unit 2 downwards Spring 80, therefore be easy to seek to improve workability when unloading light source unit 2 from appliance body 10.In addition, installation component 4 2nd face 402 of mounting plate 40 is abutted with the lower end of the margining tablet 115 of receiving portion 11, thus light source unit 2 in receiving portion 11 Position is by limitation (with reference to Fig. 7).Therefore, in luminaire 1, power supply unit 6 is not abutted with mounting plate 40, and it is possible to realize reductions The stress of light source unit 2 is applied to from appliance body 10.
Here, the appliance body 10 of luminaire 1 has receiving portion 11 and reflecting member 12 this 2 components.Moreover, illumination Utensil 1 is configured to that light source unit 2 is made to be supported on the receiving portion 11 for being installed on hanger bolt 90.Therefore, receiving portion 11 is required to use In the mechanical strength of device for supporting main body 10 and light source unit 2, and this mechanical strength is not required to reflecting member 12.Thus, The plate thickness that metallic plate of the plate thickness of the metallic plate of reflecting member 12 than forming receiving portion 11 can be made to be formed is thin.As a result, shining In funerary objects tool 1, compared with the case where receiving portion 11 and reflecting member 12 are formed by the metallic plate of identical plate thickness, shape is being compared by plate thickness In the case of forming reflecting member 12 at the thin metallic plate of the metallic plate of receiving portion 11, it is possible to realize the systems for cutting down appliance body 10 Cause this.
In addition, the side plate 121 of reflecting member 12 has the through hole 124 that the installation spring 80 for light source unit 2 is inserted.Cause And even if the locking for generating the fastener 112 due to seismic strong swing disengages, since installation spring 80 hangs over side plate The upper limb of through hole 124 in 121, therefore the possibility that reflecting member 12 is fallen down is also low.
In addition, 2 fixtures 8 (the 1st fixture 8A, the 2nd fixture 8B) that light source unit 2 has are not necessarily Same structure.It, can also unilateral like that (the 2nd peace of fixture 8 as shown in figure 23 for example, the variation as light source unit 2 Fill apparatus 8B) in replace installation spring 80 and with hook-type hook component 86.Hook component 86 is formed as hook-type and from light source The end of the installation component 4 of unit 2 protrudes outward.Hook component 86 hangs over the hook portion 114B of the side wall 111D of appliance body 10, Light source unit 2 can be made to temporarily hold in appliance body 10.Moreover, light source unit 2 hangs over the side of rear side by hook component 86 The installation spring 80 of the hook portion 114B, the 1st fixture 8A of wall 111C hang over the hook portion 114A of the side wall 111C of front side, by This is supported in the receiving portion 11 of appliance body 10.
In the above-described embodiment, appliance body 10 has a pair of of engaging portion 114,114, but appliance body 10 can also With multipair engaging portion 114,114.For example, front side side wall 111C and rear side side wall 111D respectively can also have 2 with On hook portion (engaging portion) 114.For example, side wall 111C, 111D respectively in, hook portion 114 that can also be 2 or more along The long side direction of side wall is arranged.In this case, light source unit 2 can also have and distinguish with multipair engaging portion 114,114 In conjunction with multipair fixture 8,8.In this way, in luminaire 1, as long as light source unit 2 is by will at least a pair of of fixture 8,8 at least a pair of of engaging portion 114,114 of appliance body 10 respectively in connection with to be installed to appliance body 10.
In addition, installation spring 80 be only with 1 coil part 81 basic configuration a torsion coil spring, therefore, it is difficult to Rotate the 1st arm 82 in the state of so that hook plate 820 is in parallel with the axis of coil part 81.Therefore, the installation of fixture 8 Part 85 has：1st supporting part 851 supports coil part 81 in a manner of it can be rotated about their axes；And the 2nd supporting part 852, by the 1st arm 82 can be supported in such a way that its end is rotated as fulcrum.Moreover, the 2nd supporting part 852 is configured to The fulcrum of the rotation of 1 arm 82 is configured at the position of the close installation component 4 (mounting plate 40) of the axis of coil part 81.Therefore, The flexure of hook plate 820 and the 2nd arm pieces 822 when 1st arm 82 is applied in power and rotates is eliminated, therefore can make hook plate 820 become the state substantially parallel with the axis of coil part 81.If hook plate 820 becomes substantially parallel with the axis of coil part 81 State, then operator be easy for hook plate 820 to be inserted into the hole of hook portion 114.
In the following, enumerating several variations.In the following, above-mentioned embodiment is known as " basic example ".Deformation described below Example also can suitably be combined to apply with above-mentioned basic example.
In basic example, the quantity of mounting hole 420 is 4, the number with 4 mounting holes 420 respectively correspondingly snap-latch piece 521 Amount is also 4.But as long as mounting hole 420 and 521 respective quantity of snap-latch piece 1 or more, not special to their quantity It does not limit.For example, mounting hole 420 and 521 respective quantity of snap-latch piece may also be only 1.In this case, cover 5 can also It only is fixed by caulking to installation component 4 at a position, for other positions, is threadably secured etc. to be fixed.
