  Next, the assembly procedure of the light source unit 3 will be described. However, the attachment of the second power connector 56 and the signal cable 503 to the second end 82 of the first end member 8A, and the first power line 52 and the signal cable 504 to the second end 82 of the second end member 8B. The installation of is completed in advance.

  First, the worker performing the assembly operation inserts the end of the LED board 41 between the one end (for example, the left end) of the cover 7 and the pair of projecting pieces 720 of the holding portion 72, thereby the holding portion 72 of the cover 7. Hold the LED module 4 (see FIGS. 7 and 8). Furthermore, the worker inserts the left end of the cover 7 between the pair of side surface portions 831 and the projection 86 in the first end member 8A.

  Subsequently, the worker connects the plug connector 45 of the LED module 4 to the output connector 500 of the lighting device 5. Further, the worker connects the second power supply line 55 connected to the second power supply connector 56 to the second terminal block 54 of the lighting device 5, and controls the signal cable 503 connected to the first signal connector 505.

It is connected to the control connector 502 of the device 5.

  Next, the worker accommodates the lighting device 5 and the cover 7 holding the LED module 4 in the housing 6. First, the operator inserts the hooking portion 73 of the cover 7 from the left end of the housing 6, engages the hooking portion 73 with the engagement projection 64 of the housing 6, and attaches the cover 7 to the housing 6. Further, the operator causes the pair of projections 841 of the first end member 8A to be engaged from behind with the pair of engagement holes 507 provided at the left end of the circuit board 50. The operator inserts the upper and lower ends of the circuit board 50 of the lighting device 5 into the engagement grooves 63 of the housing 6 from the left end of the housing 6 and ends the circuit board 50 in the engagement grooves 63 of the housing 6 Parts are attached and the lighting device 5 is attached to the housing 6 (see FIGS. 7 and 8). Further, the worker inserts the engagement protrusion 850 provided on the outer side surface of the pair of side plate portions 85 of the first end member 8A into the engagement groove 63 of the housing 6, and the engagement groove of the housing 6 The first end member 8A is attached to the left end of the housing 6 by engaging the engaging protrusion 850 of the first end member 8A with the third member 63 (see FIG. 11). In addition, the worker inserts the front end portions of the side walls 61 of the housing 6 into the space generated between the pair of protrusions 86 of the first end member 8A and the pair of leg portions 71 of the cover 7. In addition, since the movement range of the second power supply line 55 is regulated by the pair of side plate portions 85 of the first end member 8A, when the operator attaches the first end member 8A to the left end of the housing 6, The dual power supply line 55 is prevented from being sandwiched between the housing 6 and the first end member 8A.

  Subsequently, the worker inserts the right end of the cover 7 between the pair of side surface portions 831 and the projection 86 in the second end member 8B. Further, the worker inserts the engagement protrusion 850 provided on the outer side surface of the pair of side plate portions 85 of the second end member 8B into the engagement groove 63 of the housing 6, and the engagement groove of the housing 6 The engagement protrusion 850 of the second end member 8B is engaged with the third end member 63 to attach the second end member 8B to the right end of the housing 6.

  Finally, the operator screws the end member 8 to the housing 6. Specifically, the worker inserts the fixing screw 800 which is a tapping screw into the screw insertion hole 600 provided at the left end of the bottom wall 60 of the housing 6. Then, the operator screws the first end member 8A into the housing 6 by screwing the fixing screw 800 inserted into the screw insertion hole 600 into the screwing portion 840 of the first end member 8A (see FIG. 7). Similarly, the worker inserts a fixing screw 800 which is a tapping screw into a screw insertion hole 600 provided at the right end of the bottom wall 60 of the housing 6. Then, the operator screws the second end member 8B into the housing 6 by screwing the fixing screw 800 inserted into the screw insertion hole 600 into the screwing portion 840 of the second end member 8B (see FIG. 7).

  The assembly operation of the light source unit 3 is completed by the above-described procedure. However, the above-described assembly procedure is an example, and it is also possible to change the order of some procedures.

  In the light source unit 3, corresponding projections 841 of the two projections 841 provided on the bottom plate portion 84 of the end member 8 are provided in each of two engagement holes 507 provided on the circuit board 50 of the lighting device 5. One by one. Therefore, the light source unit 3 can improve the bonding strength between the circuit board 50 and the end member 8 as compared to the case where one protrusion 841 and one interlocking hole 507 are engaged.

  By the way, the plurality of engagement portions and the plurality of engagement portions are not limited to the plurality of protrusions 841 and the plurality of engagement holes 507. For example, at one end (left end) in the longitudinal direction of the circuit board 50, a plurality of grooves whose one end side is opened is provided, and a plurality of protrusions protruding from the bottom plate portion 84 of the end member 8 along the longitudinal direction of the circuit board 50 May be provided. The light source unit 3 causes displacement of the lighting device 5 along the longitudinal direction of the circuit board 50 by engaging the plurality of protrusions and the plurality of grooves in one-to-one correspondence along the longitudinal direction of the circuit board 50. May be regulated. However, the structure in which two protrusions 841 and two interlocking holes 507 are interlocked along the direction (thickness direction) intersecting the longitudinal direction of the circuit board 50 is the interlocking between the projections 841 and the interlocking holes 507. It is possible to improve the strength of the case (the degree of difficulty in disengagement).

  Further, the plurality of engagement portions are not limited to the protrusions, and the plurality of engagement portions are not limited to the holes. For example, the plurality of engagement portions may be a plurality of holes penetrating the bottom plate portion 84 in the thickness direction, and the plurality of engagement portions may be projections projecting from the front surface or the back surface of the circuit board 50. However, providing the plurality of projections 841 in the bottom plate portion 84 is relatively easy as compared to providing the plurality of projections on the circuit board 50, and an increase in the manufacturing cost of the circuit board 50 and the end member 8 can be suppressed .

  Furthermore, since the two projections 841 are provided on the end member 8 (the first end member 8A), the components of the light source unit 3 are compared to the case where the two projections 841 are provided separately from the first end member 8A. The number of points can be reduced to reduce the manufacturing cost. In addition, since the first end member 8A and the housing 6 are screwed by the fixing screw 800, the light source unit 3 has a joint strength between the bottom plate portion 84 supporting the two protrusions 841 and the housing 6 It can improve.

  In the light source unit 3, the lighting device 5 and the first end member 8 </ b> A are inserted into the housing 6 along the longitudinal direction of the housing 6 and accommodated in the housing 6. Therefore, the light source unit 3 can collectively accommodate the lighting device 5 and the first end member 8A in the housing 6, and can improve the workability of the assembly operation. Moreover, since the light source unit 3 combines the pair of engagement grooves 63 with the attachment of the first end member 8A and the attachment of the lighting device 5, the structure of the housing 6 is simplified to reduce the manufacturing cost. be able to.

  Here, in the light source unit 3, the material (polycarbonate resin) forming the cover 7 and the material (PBT resin) forming the end member 8 are different, and the dimension in the longitudinal direction of the cover 7 is the longitudinal direction of the end member 8 It is considerably larger (longer) than the size of. Therefore, in the light source unit 3, the expansion amount of the cover 7 during the lighting of the LED module 4 is considered to be larger than the expansion amount of the end member 8. Therefore, if the first end portion 81 and the end of the cover 7 are in contact with each other in a state in which the LED module 4 is turned off, the cover 7 and the first end are expanded when the cover 7 expands while the LED module 4 is lit. Excessive stress may occur in the end portion 81.

  Therefore, in the light source unit 3, the dimensions and the like of the cover 7 are designed such that a slight gap (for example, 1 mm to 2 mm) is left between the first end 81 and the end of the cover 7 at normal temperature. Therefore, even if the cover 7 thermally expands during lighting of the LED module 4, the end portion of the cover 7 hardly contacts the first end portion 81, so excessive stress may occur in the cover 7 and the first end portion 81 The sex can be greatly reduced. However, if there is a gap between the end of the cover 7 and the first end portion 81, foreign matter such as dust or insects penetrates the gap into the light source unit 3 (in the space surrounded by the cover 7 and the LED module 4). There is a risk of

  Therefore, in the light source unit 3, the seal portions 30 are respectively disposed between the first end portions 81 of the end members 8A and 8B and the both end portions of the cover 7 (FIGS. 7 and 10). The seal portion 30 is formed in, for example, a substantially semicircular ring shape by silicone rubber (see FIG. 10). The seal portion 30 seals the gap between the first end portion 81 and the cover 7 by bringing the seal into close contact with the first end portion 81 and the cover 7 (see FIG. 7). The seal portion 30 seals the gap between the first end portion 81 and the cover 7, thereby suppressing the entry of foreign matter into the light source unit 3 and stress generated in the end portion of the cover 7 and the first end portion 81 at the time of thermal expansion. Can be reduced.

  Next, the construction procedure of the lighting fixture 1 will be described.

  A worker who performs construction work first attaches the tool body 2 to a construction material (for example, a wall). The operator inserts a mounting screw such as a wood screw into the pair of mounting holes 206 of the main body 20 to screw the main body 20 to the wall.

  Subsequently, the worker inserts the housing 6 of the light source unit 3 into the main body 20 from the front. The operator bends the pair of displacement portions 211 of the support member 21 outward by pushing the engaging portions 210 of the support member 21 at the upper and lower end portions of the rear end of the housing 6. Then, the second displacement piece 211 B of the displacement portion 211 and the engagement portion 210 pass through the opening 203 of the side portion 201 and are displaced out of the side portion 201. However, the displacement of the second displacement piece 211B and the engagement portion 210 is regulated by the regulation portion 204 (the regulation piece 2040).

  The worker resists the spring force (pressing force) of the spring portion 212 even after the pressing surface 2120 of the spring portion 212 of the support member 21 comes in contact with the rear surface of the housing 6 of the light source unit 3. Insert 6 Then, when the engaging portion 210 of the support member 21 reaches the recess 610 of the side wall 61, the displaced displacement portion 211 returns to the original state. Then, when the worker releases the light source unit 3, the housing 6 pressed by the spring portion 212 moves forward, and the engaging portion 210 of the support member 21 engages with the engaged portion 62 of the housing 6. Match. In this manner, the worker causes the casing 6 to be supported by the pair of support members 21 and attaches the light source unit 3 to the main body portion 20.

  As described above, the worker can attach the light source unit 3 to the instrument body 2 without using a tool such as a driver. Therefore, the lighting fixture 1 can aim at shortening of the working time which an installation requires.

  Here, the engaged portion 62 is provided over the entire length of the side wall 61 in the longitudinal direction, and is formed wider than the engaging portion 210 in the longitudinal direction of the housing 6. Therefore, the engaging portion 210 and the engaged portion 62 are movably engaged with each other along the longitudinal direction of the side wall 61. That is, the housing 6 of the light source unit 3 is supported by the support member 21 so as to be movable in the longitudinal direction of the main body portion 20 of the tool main body 2 with respect to the tool main body 2. As described above, since the housing 6 is supported by the support member 21 so as to be movable along the longitudinal direction of the main body portion 20, excessive stress is applied to the housing 6 from the support member 21 when the housing 6 is thermally expanded. It can be prevented from being applied. However, the movement range of the casing 6 of the light source unit 3 (the movement range of the engaging portion 210 with respect to the engaged portion 62) is limited to the range in which the engaging portion 210 does not contact the second end portion 82 of the end member 8. . That is, in the lighting fixture 1 of the present embodiment, the second end portion 82 of the end member 8 corresponds to a restricting portion that restricts the moving range of the engaging portion 210.

  Next, the illumination system 10 of the present embodiment will be described. The lighting system 10 comprises a plurality of lighting fixtures 1. However, the plurality of lighting fixtures 1 included in the lighting system 10 includes several types of lighting fixtures 1 having different longitudinal sizes (total lengths). For example, as shown in FIG. 14, the lighting system 10 includes a lighting fixture 1 (1A) of a standard length and a lighting fixture 1 (1B) having a length twice as long as the standard length. However, the two luminaires 1A and 1B have substantially the same configuration except that the size (total length) in the longitudinal direction is different.

  The two luminaires 1A and 1B are arranged in a line along the longitudinal direction. Here, the device body 2 of the lighting device 1A and the device body 2 of the lighting device 1B are connected by the connecting portion 205 provided on the main body portion 20 of each device body 2. The connecting portions 205 provided at both ends in the longitudinal direction of the main body portion 20 are symmetrical with respect to a center line along the longitudinal direction of the main body portion 20. Therefore, when the connecting portions 205 of the respective main body portions 20 engage with each other in the vertical direction and the left and right direction, the two main body portions 20 can be mechanically connected to each other in a line along the longitudinal direction. .

  And each light source unit 3 of lighting fixtures 1A and 1B is attached to each main-body part 20 fixed to the wall. In this case, the second power supply connector 56 of the lighting fixture 1A and the first power supply connector 53 of the lighting fixture 1B are electrically connected (FIG. 16). That is, alternating current power is supplied to the two lighting fixtures 1A and 1B by the feed wiring of the power supply line. Further, the first signal connector 505 of the lighting fixture 1A and the second signal connector 506 of the lighting fixture 1B are electrically connected. That is, the control signal is transmitted to the two lighting devices 1A and 1B by the feed wiring of the signal line.

  Here, at both ends in the longitudinal direction of the light source unit 3, the end of the cover 7 and a part of the end member 8 protrude outside the housing 6. Furthermore, the side portions 201 of the main body portion 20 are disposed outside the both ends in the longitudinal direction of the housing 6. That is, the moving ranges of the first power connector 53 and the second power connector 56 electrically connected to each other, and the first signal connector 505 electrically connected to each other and the second signal connector 506 in the vertical direction Regulated by a pair of sides 201. Therefore, when viewed from the front, the first power connector 53, the second power connector 56, the first signal connector 505, and the second signal connector 506 do not protrude outside the fixture body 2, and the appearance quality of the lighting system 10 is improved. It can improve. Moreover, in the luminaire 1 (1A; 1B), a component for restricting the movement range of the first power supply connector 53 and the like is not necessary, so components other than the device body 2 and the light source unit 3 are required. The workability of the construction work can be improved as compared with the case.

  The lighting system 10 also has an input fitting 11 and a termination fitting 12.
